More and more electric cars Boom for Battery manufacturer

Status: 06/17/2021 10:13 a.m.

The growing number of e-cars on the streets is causing the battery market to grow strongly. One EU country in particular can catch up significantly with its Asian competition.

From Oliver Feldforth, MR

For years it was talked about, now the boom in electric mobility really seems to be there. Electric cars are very popular at a leading Frankfurt dealership. One seller says that what is delivered to him can also be easily sold.

The electric cars have contributed to the fact that the corona pandemic could not harm the battery market in Germany. Last year there was an increase of 35 percent. “Above all, the volume of the market for lithium-ion batteries has increased enormously,” says Christian Eckert from the Central Association of Electrical Engineering and Electronics Industry ZVEI. Overall, this segment grew by 63 percent. And that is mainly due to electromobility.

The recycling rate should increase

A battery is only as green as the material and the electricity used to make it. Even the electric car is only as green as the electricity with which it is charged. When it comes to battery recycling, German industry is on the right track, said Christian Rosenkranz, Chairman of the ZVEI Batteries Association. The recycling rate for classic batteries is 80 to 90 percent, while it looks worse for lithium-ion batteries, which are in increasing demand. The industry wants to achieve a rate of 65 percent in four years.

Environmentalists see a need for action. “It is not only in Germany that we have to set high social and ecological standards for the production of batteries,” says Benjamin Stephan from Greenpeace. “The car manufacturers are responsible for this, but politics must set clear rules for all companies.”

Poland leads the way in Europe

Germany imports batteries. The manufacturers from Europe overtook the Asian competition for the first time last year. In Europe, Poland is the leading producer, in Asia it is China, according to Christian Eckert from the ZVEI.

And electromobility will continue to grow. Volkswagen sees it that way too. The car manufacturer plans to set up six battery cell plants of its own in the next few years. According to Ralf Brandstätter, head of the Volkswagen brand, by 2030 at least 70 percent of all new Volkswagens in Europe should be electric vehicles, in North America and China more than half.

Solid-state batteries as the technology of the future

The decision as to which drive for cars comes after the classic combustion engine seems to have been decided for the time being. “The battery-electric drive is the most efficient and significantly more economical than fuel cells and combustion engines,” said Benjamin Stephan from Greenpeace. “With the same amount of renewable electricity, a car with a fuel cell can only go half as far as a battery-electric one.”

In the case of car batteries, solid-state batteries are to replace lithium-ion technology. It does not require cobalt, which under questionable circumstances is mainly extracted in Africa. For environmentalists, electromobility is only part of the necessary turnaround in traffic. And so Greenpeace is also calling for a change in mobility towards an intelligent transport system in which bicycles, buses and trains play a bigger role

Around the world, unsafe recycling of lead batteries (mainly from cars) is widespread. Perry Gottesfeld of Occupational Knowledge International (a San Francisco-based organization that campaigns worldwide against industrial pollution) called lead pollution “the most serious health threat to children”. In Senegal, 18 children died within three months of cerebral palsy caused by lead poisoning from a battery recycling plant on the outskirts of Dakar. In addition to those 18 children, hundreds more children in the residential area were poisoned. A person cooks lead manually in the Pesarean (Indonesia). Image source: Pure Earth On the other side of California, a giant lead smelter is located in the city of Torreon (Mexico), which has a history of childhood blood poisoning in the neighborhood and stretches back half a century. Air, soil and water pollution has long been documented around small and large lead smelting and recycling plants. Doctors all know that lead can be easily inhaled or swallowed, and when it enters the bloodstream, lead dust will immediately travel from the digestive tract to the brain. On the other hand, it should be known that lead is a potent neurotoxin and at no level has ever been deemed safe. Besides causing fever and affecting the gastrointestinal tract, lead poisoning also damages intellectual development in young children even at a low dose, reduces intelligence quotient (IQ), loss of attention. , and emotional disorders. Workers disintegrate car batteries in preparation for lead recycling in Patna, India. Image source: Pure Earth Lead poisoning is also believed to be the cause of outbreaks of violent behavior in communities in the United States and around the world. The UNICEF report noted: Lead wreaks havoc on the body in a silent way. One-third of children worldwide are suffering from lead poisoning from recycled batteries and other sources. Fatty profits but a danger to human health An estimated 85% of the lead used today is in batteries, mainly used in cars. And when the battery runs out, 99% of the expired battery will be recycled to create a new battery. The recycling battery business is very lucrative, this is a money-making business. Tens of thousands of people breaking batteries and smelters around the world are looking for ways to monetize it, collecting an abundance of used batteries and turning them into brand-new products. According to the International Lead Association, in London: “More than 6 million tons of lead are collected each year. Lead batteries are the most recycled consumer product in the world, thanks to recycling they no longer have to be mined.” Because of very little regulation, in many countries around the world, small-scale operators compete with the legal battery industry. “Total half of all batteries are in the informal economy, where unregulated and often illegal recycling processes have broken battery cases, spilling lead acid and dust into the ground. Lead smelting in open-air furnaces has spewed toxic fumes and dust around residential areas,” according to a report published in June 2020 by Pure Earth and UNICEF. With the rapid development of African economies, more than 800,000 tons of lead leach out of batteries each year on the subcontinent. And the consequences for human health and the environment have already begun to emerge. Two years ago, Mr. Gottesfeld completed research showing that lead poisoning had spread to the land around battery recycling plants in crowded slums or near schools in cities such as Dar es. Salaam (Tanzania), Lagos (Nigeria) and the port of Tema (Ghana). Lead contaminated soil is excavated in Dong Mai ward (Hanoi, Vietnam). Image source: Pure Earth In addition to Africa facing serious lead poisoning problems, Southeast Asia is also facing a similar crisis. Mr. Bill Daniell (School of Public Health, University of Washington) is the lead author of a 2015 study on lead exposure around Dong Mai ward (Ha Dong district, Hanoi), where many households are engaged in recycling. battery processing. More than 100 children in Dong Mai were tested and all showed high blood lead levels of more than ¼/45 micrograms/decilit, which is nine times the safe limit in the US. In India, a study published in 2019 by Toxics Link (an NGO based in New Delhi) announced that 90% of lead batteries in India in recycling plants are in the informal sector. awake. The study mapped residential areas in major cities like New Delhi, where lead-battery recycling plants operate without any official supervision. Nguyen Thanh Hai ( According to e360.yale.edu )

VinFast electric bus during test run Not only buses, coaches should also be encouraged to use trams Air pollution and fine dust threaten people’s quality of life. Every year, Vietnam has to pay a large amount of money, about 8-10 billion USD to import gasoline. Part of this is spent on operating traditional fossil fuel-powered vehicles. In addition to the proposed inner-city electric buses for application in Hanoi and Ho Chi Minh City. In Ho Chi Minh City, it is thought that the government should consider the early policy of putting electric-powered intercity passenger cars into operation in order to both exploit the superiority of electric vehicle technology, while protecting the environment and bringing a a new look for public passenger transport in the new era. The world’s two major problems, which are environmental pollution due to emissions and energy security due to the finiteness of fossil energy sources (coal, oil, gas) have gradually become urgent. Air pollution, fine dust in Vietnam has become serious with big cities like Hanoi, Ho Chi Minh City, etc. Ho Chi Minh. Here, it is recorded that there are maximum number of days in a year with the most dramatic air quality index – the most polluted air in the world. In the past two years, authorities at all levels have met to discuss and direct long-term radical solutions to further strengthen the control of air pollution, including the control of carbon emissions and fine dust from the air. means of transport. And fossil energy sources are not available in all countries. Vietnam is one of the importing countries, still heavily dependent on the world’s oil (although it is also partly domestic), it is estimated that it still has to import about 8-10 billion USD per year. With zero emissions and using electricity instead of petrol, electric vehicles are said to be a breakthrough solution for Vietnam in the context of the need to strengthen air pollution control, ensure energy security and suitability. with the development trend of the world’s means of transport. Simple structure of electric vehicles compared to vehicles using internal combustion engines “Electric vehicle” (EV) is often understood as a vehicle with an electric motor drive system. From the outside, an electric car looks like a car with an internal combustion engine (petroleum car). However, except for some parts and components for sharing, about 70% of the components of the two vehicles are different. The significant difference between electric vehicles and vehicles using internal combustion engines is the number of moving parts. Electric vehicles have only one moving part, which is the electric motor (motor), while cars using internal combustion engines have tens of thousands of different parts. Important components of electric vehicles include: battery, electric motor control system, regenerative braking system and powertrain. The number of spare parts for moving parts is less than in electric cars, which leads to another important difference, which is that electric cars require less maintenance (more economical to operate) and safer. safer, in addition to the advantages of environmental protection, civilized and modern technology. Why electric cars are becoming more and more popular At the United Nations Climate Change Conference 2015 (COP 21) held in Paris (France), the participants reaffirmed their efforts to strengthen the response to climate change. The Paris Agreement announced in December 2015 has set a target to limit global temperature rise to below 2 degrees Celsius. This goal can only be achieved when the energy and other sectors significantly reduce emissions. greenhouse gas emissions. The transport sector accounts for about a quarter of emissions from energy-related industries. The goal of reducing greenhouse gas emissions to contribute to achieving the goal of reducing global warming below 02 degrees Celsius can only be achieved with a strong commitment of the transport sector. The Sustainable Development Report of the International Energy Agency (IEA) has shown that, to achieve this goal, by 2050, the world’s transport sector must contribute at least one-fifth of total greenhouse gas emissions. cuts from energy use activities. Electric cars are identified as a key factor contributing to reducing greenhouse gas emissions in the transport sector, increasing energy efficiency, reducing greenhouse gas emissions in general, encouraging the development of new energy sources and recycled energy. In the context of rapid urbanization, the development of electric cars also contributes to reducing air pollution and noise pollution in big cities. The main obstacles to the development of electric cars are the initial cost of the car and the time available between two charges of the battery. However, the recent rapid development of science and technology has shown positive signs. According to a recent report by the US electric car company Proterra, a single charge for the bus can be up and running for 650 km and the price is becoming more and more relevant to the market to ensure more competitive exploitation than traditional gasoline-powered vehicles. Level of use of electric vehicles in countries around the world To date, China is the leading country in production, domestic consumption and export, with the famous electric car manufacturer BYD. In China, according to the data at the end of 2018, the total number of electric buses put into operation is over 421,000 units, Shenzhen city uses 100% of electric vehicles in public passenger transport, while Beijing and Shanghai , the utilization rate of electric buses has reached over 80%. Electric buses are increasingly popular in provinces and cities in China. Europe ranks 2nd among countries using electric vehicles with 2,250 units, the number of electric vehicles used will increase as some European countries such as the Netherlands set a target to convert and use 100% electric vehicles. (including buses, coaches plus and private cars) by 2024. The United States is also the country that is starting to shift towards using more electric vehicles. Although there are only over 300 electric buses in the United States, the number of electric buses is increasing in the near future, with the city of Los Ageles having just decided to buy 155 electric buses to serve all passenger transport activities. in this city. With the new energy policy (Green New Deal), led by many famous electric vehicle manufacturers such as Telsla, Proterra and even Apple recently announced the new Apple car electric car model, there is sure to be a boom in usage. electric vehicles in the United States under the new administration are clearly visible. For electric vehicles, environmental protection is always a top priority Why use an electric car? As mentioned above, electric vehicles are vehicles without chimneys, do not emit CO2, greenhouse gases into the environment. Therefore, the exploitation of electric vehicles in passenger transport is completely environmentally friendly, which is not controversial. Many researchers, policy makers still argue. The first is the traceable environmental issue of electric vehicles, that is, the source of electricity that electric vehicles use is clean electricity, that is, electricity using renewable energy such as solar power, wind power … or electricity from heat. Obviously, over the past time, the Government has called on businesses to invest in the production of solar power, rooftop voltage and wind power…, this electricity has been purchased by the state and connected to the national grid. Only the current supply has not met the demand and more clean electricity is needed to connect to the network. The second is the problem that the production of batteries for electric vehicles is still energy-intensive and emits a significant amount of CO2. As stated, today’s technology is evolving like crazy. As the demand for electric vehicles and batteries increases, mass production of large capacity batteries will result in better environmental control and lower loss and emissions. Here, it is a matter of deciding for the electric vehicle industry to have a direction in which to invest, cooperate and develop. When domestic manufacturers have been proactive in technology, it is possible to produce and recycle used batteries, thereby closing the production and exploitation process effectively and ensuring the problem. environment. What are the implications for passenger transport in Vietnam in the new period? Facing the environmental context, the challenge of air pollution as well as ensuring national energy security, Vietnam should consider the development of electric cars as a breakthrough policy for technology development, domestic auto industry. The introduction of electric vehicles into transport operation has really been a push to change for the progress to serve the travel needs of people and socio-economic development in the new period. The use of electric vehicles for public passenger transport is not only in the inner city as the project of electric buses in Hanoi and Ho Chi Minh City. Ho Chi Minh City as the media recently mentioned, but also hereby recommended that the State should have a policy to encourage the development of electric vehicles for inter-provincial passenger transport (both for fixed and non-fixed routes). To do this, the state has policies to socialize and encourage transport business owners to use electric vehicles in transport business activities; encourage businesses to invest in charging station infrastructure at rest stops, bus stations and other concentrated stops for re-energized vehicles to serve well for transport activities. In short, the policy to encourage the use of electric vehicles is a right one, in terms of both environmental protection as well as energy security. In addition to electric buses as currently proposed to be applied in the inner city of Hanoi, Ho Chi Minh City. Ho Chi Minh City is also considering the application of intercity buses running on electricity. With a national electric passenger transport network being formed, improving user experience, increasing the quality of transport services, electric cars will have a good future in Vietnam, gradually replacing the traditional means of transport. fossil fuel-powered transportation.

VinFast is building electric car charging stations The Ministry of Finance has just sent a document to the Ministry of Industry and Trade, the Ministry of Justice, the Ministry of Natural Resources and Environment and the Ministry of Transport, to respond to tax incentives for battery electric cars. Proposals for tax incentives only mention battery electric vehicles (BEVs). Currently, according to statistics, battery electric vehicles account for about 1% of electrified vehicles in Vietnam. Electric vehicles include many types of vehicles. In addition to gasoline-powered vehicles combined with electric energy (including HEV, PHEV) and Hydrogen-fueled cars (FCEV), there are currently BEV (pure electric) battery electric cars. Completely electrically charged from an external source. The two types of hybrid vehicles move mainly with internal combustion engines, in parallel taking advantage of the benefits of an electric powertrain consisting of an electric motor with a battery. FCEVs have an advantage over BEVs when the charging time is short, but the production of water makes hydrogen fuel-powered electric vehicles only suitable for island nations, arid areas, and unsuitable for urban areas. big. Meanwhile, BEV battery electric vehicles have a minimalist structure, run short distances, can consume electricity everywhere, have great advantages in urban areas. With three types of vehicles HEV, PHEV and FCEV all use gasoline and gas, so they have more impact on the environment than BEV models. Electric cars are becoming an advantageous choice to replace vehicles using internal combustion engines, especially battery electric cars (BEVs). Many countries around the world have had preferential policies and tax support to prioritize the development and production of battery electric vehicles. According to the Ministry of Finance, Vietnam has a number of preferential policies for electric vehicles. Accordingly, electric cars carrying passengers with less than 9 seats are entitled to the special consumption tax rate of 15% (ie 10% reduction compared to cars of the same type using fossil fuels; 10-16 seats are allowed to be used for cars of the same type using fossil fuels. tax rate of 10% (5% reduction compared to cars of the same type running on gasoline) and the tax rate of 16 to less than 24 seats is applied at the tax rate of 5% (5% reduction compared to cars of the same type running on petrol). At the same time, the Law on Special Consumption Tax No. 27/2008/QH12 also stipulates the special consumption tax rate for environmentally friendly vehicles. Specifically, vehicles running on gasoline combined with electric energy and bioenergy, in which the proportion of gasoline used does not exceed 70% of the energy used by the vehicle, is entitled to a tax rate of 70% for vehicles of the same capacity. species. For cars running on bio-energy, the special consumption tax rate is only 50% compared to cars of the same type. Meanwhile, about the current registration fee, there are only preferential rates for buses using clean energy while there is no policy applicable to other environmentally friendly vehicles. To encourage production and stimulate consumers to use BEVs, contributing to reducing the emissions released into the environment by vehicles, contributing to the protection of the ecological environment and based on the outstanding advantages of vehicles. BEV, the Ministry of Finance is planning to propose new incentives for this model. An electric vehicle charging station in Ho Chi Minh City Specifically, incentives related to excise tax fall under the jurisdiction of the National Assembly. Therefore, the National Assembly must amend the excise tax law. The Government has also assigned the Ministry of Finance to preside over the overall assessment of the implementation of the excise tax policy on automobiles in the past time to study and amend the excise tax law accordingly. Regarding the registration fee under the authority of the Government, when there is a need to change, it will amend and supplement Decree No. 14/20216/ND-CP on registration fee. The Ministry of Finance said that in the past time, it has also received recommendations from a number of associations on adjusting registration fee rates to remove difficulties for businesses. Therefore, the Ministry of Finance is also evaluating the overall policy on registration fees and is expected to submit it to the Government in October. The Ministry of Finance also asked agencies to propose specific content on special consumption tax incentives and registration fees related to battery electric vehicles to summarize and report to the Government. Battery-powered electric vehicles currently account for a very small percentage in Vietnam. According to data from the Vietnam Automobile Manufacturers Association (VAMA), the number of electrified vehicles registered in Vietnam is still very modest, accumulating just over 1,000 units by the end of 2020. of which BEVs only account for about 1%, the rest are HEV and PHEV models. According to the Ministry of Finance, currently only VinFast invests in producing electric vehicles, according to reports, VinFast has now launched the first battery-powered electric car model. The factory has a capacity of 250,000 vehicles per year and the brand is focusing on battery electric vehicles with 9 seats or less and electric buses with 24 seats or more. Also according to the Ministry of Finance’s assessment, the biggest obstacle facing Vietnam today is the lack of charging station infrastructure, the main source of power for power supply is using fuel sources with high CO2 emissions, accounting for nearly half of the total mobilized electricity output, while the electricity generated from renewable energy accounts for a small proportion, about 4.3% and this is considered an unstable power source.

Apple hires former BMW CEO for electric car project. The iPhone maker’s car-making efforts, known as Project Titan, have progressed unsatisfactorily since 2014. At this point, Apple began designing its own vehicles for the first time. In December 2020, Reuters reports that Apple is working on self-driving car technology and aims to produce a passenger vehicle, including breakthrough PIN technology, by 2024. Previously, in 2018, the tech giant Apple hired former Tesla design chief Andrew Kim, sparking speculation that Apple was once again trying to develop its own car. The timing of Apple’s hire of Andrew Kim seems to coincide with Doug Field’s return to Apple as well. Looking at the profile of Andrew Kim, this designer has contributed to Tesla’s hit models Model 3, Model S, Model X, Model Y as well as Roadster V2 and Semi. Before taking on a major role at Tesla, Kim spent three and a half years at Microsoft, where he developed user interfaces and Windows 10 products such as HoloLens and Xbox One S.

This tablet has an enlarged screen size of 8.7 inches, Dolby Atmos multi-dimensional sound technology, 8mm thin and 371g light. Galaxy Tab A7 Lite owns an 8.7-inch screen Galaxy Tab A7 Lite owns a large screen with a display size of 8.7 inches with a screen ratio of 1340×800 pixels, a thin screen border that helps the screen body ratio (screen body ratio) up to 81%. Solid metal frame design. Despite using metal edges and owning a large screen size, Galaxy Tab A7 Lite has a light weight of 371g, making it easy for users to hold. Up to 81% screen-to-body ratio The machine has a unibody metal frame design The sound on the Galaxy Tab A7 Lite is also improved thanks to a dual speaker system that supports Dolby Atmos technology to create surround sound effects to optimize the audio-visual experience. Galaxy Tab A7 Lite is equipped with Helio P22T processor (MT8768T, Quad 2.3Ghz & 1.8Ghz) with multi-application and graphics performance scores increased by 75% and 92% respectively compared to Samsung Tab A8. RAM capacity is also upgraded to 3GB. Galaxy Tab A7 Lite equipped with Helio P22T processor, 3GB Ram The battery of the device is 5,100mAh with 15W fast charging technology and Type-C connection port Samsung has integrated a battery capacity of up to 5,100mAh with 15W fast charging technology and Type-C port for Galaxy Tab A7 Lite, to give users a seamless experience.

Referring to the Galaxy M, we will probably immediately think of a very popular Samsung product in the past few years, but the boldest is probably just the extremely large battery capacity left. The machine is quite clumsy, the performance has to be reduced to save battery, the screen and the camera are only enough to use. But this will change on the latest Galaxy M12. The first 90Hz monitor in its segment Today’s high-frequency screen seems like a common device, but it is for smartphones priced above 5 million VND or more, so not everyone has the opportunity to experience high frequency scanning. With the Galaxy M12, Samsung is determined to bring this device down and popularize the high-frequency screen for everyone. Although other parameters such as resolution, color display ability, brightness are all very normal in the price range, it is undeniable that the 90Hz screen is too valuable equipment on this machine. The swipe and touch experience is very smooth, different from Samsung’s previous smartphones of this price range. Thought that the Exynos 805 chip would not be able to bear a 90Hz screen, but on the contrary, the machine performed very smoothly, even more than some machines costing more than a few million. And the scan frequency here is also self-adapting, meaning that depending on the content and user operation, the screen will automatically adjust the scan frequency up or down to make it easier to monitor and save power. If you’ve used Samsung’s AMOLED screen before, you’ll find colors a bit pale, but when you upgrade from another TFT or LCD phone, you’ll be pleased with the color reproduction on the M12. Exynos 850 is “tailored” One of the reasons why the screen on the Galaxy M12 is so smooth is because there is a solid foundation behind it. Specifically here is the Exynos 850 chip as “measured” for this machine. If last year’s Galaxy A21s used this chip but still had a bit of lag, then to the Galaxy M12, Samsung has optimized its software according to the M12’s hardware, overcoming that situation. When playing simple games like last year’s Galaxy A21s, Temple Run 2, … the device can play fine, and games that require strong configuration like Call of Duty or Asphalt 9, you must install at the lowest graphics level. 5000mAh battery with fast charging With a sufficient configuration, not too high resolution screen but with adaptive scanning frequency feature, Samsung confidently equips the Galaxy M12 with a 5000mAh battery that can be used comfortably for two days without plugging in a charger. Unless listening to calls and surfing social networks like Facebook, Tik Tok continuously, it is still more than a day. Galaxy M12 also has Samsung built-in 15W fast charging technology, which is anyway better than the 10W or 5W charger that some smartphone manufacturers provide for popular phones in the segment. Fully charging the device takes about 2 hours. Young appearance Previously, the Galaxy M often had a rather clumsy appearance, mainly coming from the thickness of the device, the colors were also not many accents. Coming to the Galaxy M12, you will have a machine with a thickness of 9.7mm and a weight of 214g, numbers that cannot be said to be thin and light but convincing enough for a machine with a large 5,000mAh battery. Samsung is also quite smart when it mainly uses soft curves to reduce the more awkward and angular parts. Galaxy M12 sold in Vietnam will have 3 colors including Attractive Black, Elegant Blue, and Trendy Emerald Green, all colors that are not too ‘hard’, still youthful enough and I especially like the vertical lines. The body combines tiny diagonal lines, making it feel better to hold, more friction, without leaving stains, scratch-resistant, these are all essential details for a machine. geared towards mobile usage as much as the Galaxy M. Camera is quite in the 3 million segment Galaxy M12 is fully equipped with all the most popular lenses today, including, wide angle, super wide angle, macro and depth. Experience fast, the image quality of the M12 is quite good from detail, contrast, focus speed, or color quality. Compared to competitors in the M12 segment, it will be marginally better in super wide-angle and macro image quality. Enough for you to use on long trips. Some photos taken from Galaxy M12: Photo: Quang Dong

The notable points of the device include: 8-core processor, 90Hz refresh rate screen, 5,000mAh high-capacity battery, 48MP quad-camera set, reasonable price. However, due to the high capacity battery in the mid-range price segment, the device will be a bit thick and heavy (9.7mm, 214g). Besides, the screen border is also a bit thick. The device has a large screen, 6.7 inches, HD + resolution. This screen is large enough for surfing the web, social networking, watching videos. The 90Hz refresh rate is rare in the segment, making screen surfing smoother. Most machines in the 3-4 million dong segment have a 6.5-inch screen, so this size of the M12 is large. Only two models Vsmart Active 3 and Joy 4, which were heavily discounted after VinSmart decided to withdraw from the market, have a FullHD + screen, higher than the HD + level of the M12. Despite being at a low price, the device is equipped with a 4-camera cluster, enough for most basic shooting needs. In which the main camera has a resolution of 48MP, a large aperture of f / 2.0. The 5MP ultra-wide camera has a 123-degree shooting angle. The 2MP macro camera allows users to focus at a short distance of only 3-5cm. In this segment, only Xiaomi Redmi 9T has the same 48MP camera as the M12. Other devices have lower resolutions. Meanwhile, the M12’s font removal camera with a 2MP sensor helps to measure the depth of field, creating photos that clarify the subject, blurring the scene behind. Besides, the camera also has a professional shooting mode, allowing deep intervention in the photography features. In addition, this camera has additional features to capture panorama, capture food. The selfie camera with 8MP sensor supports portraiture, focuses on the subject, blurs the background. This camera has additional beautifying functions, creating stickers, or adding color filters. Most of the M12’s competitors have 5-8MP selfie cameras, but a few Vsmart models as mentioned have superior configurations. The back of the device is made from a plastic shell, with a textured design to help eliminate the possibility of fingerprints. The rounded corners make it more comfortable to hold. The machine is quite thick, so some people will feel like holding it quite firmly. M12 has 3 colors black, blue, turquoise. One of the strengths of the device is a 5,000mAh battery, integrated with 15W fast charging technology. With this battery level, the device can be used comfortably for 1 day, or lasts for two days if used lightly. According to the manufacturer, with a full battery will help the device surf the web for 1 day, talk for 2 days and listen to music continuously for 3 days. The battery capacity of the M12 is at a high level compared to many competitors, but some devices like Redmi 9T, Realme C15 have a 6,000mAh battery. The device uses an 8-core Exynos 850 processor, clocked at 2GHz, 3GB or 4GB RAM, 32/64GB internal memory (card slot reaches 1TB). This configuration can hardly install too many applications or games, so users need to select the necessary applications and games to install. In general, at a price of nearly 4 million VND, the M12 is a reasonable choice when compared to many competitors. However, because it is aimed at new users, it will be difficult for the device to meet heavy games, or have too high requirements for image quality. M12 is priced at 3.49 million for the 3GB RAM / 32GB ROM version. The 4GB/64GB model alone costs VND 3.89 million.

Strength of Tesla electric car is the ability to upgrade the vehicle’s software over a network connection, similar to what today’s smartphone models do. However, not every software upgrade that the US automaker has released also brings benefits to users. Recently, a court in Norway has declared Tesla brand penalty due to the limitation of the vehicle’s charging current as well as the vehicle battery capacity. Accordingly, the US electric vehicle brand must compensate 16,000 USD (365 million VND) for each customer affected by this software upgrade. It is known that most Tesla models with limited charging current and battery capacity are Model S and Model X vehicles equipped with high-capacity 85 kWh battery packs. Currently this battery pack has been discontinued in 2016. Tesla electric vehicle models equipped with 85kWh battery packs have been affected by the software update Over the past few years, many Tesla car users have complained about the car having a shorter range after a major software update rolled out in 2019. In connection with this incident, many users have created many Hot topics and discussions on the Reddit platform and Tesla car user forums. Some users said that after the Tesla electric car was upgraded with software, the vehicle’s travel range was reduced by about 20 km compared to before. Also because of the above incident, many people have filed a lawsuit in the California court. In this indictment, the user accuses the Tesla car brand of using the car battery capacity limit feature through a software update. As such, it appears that Tesla’s software update affects not only users in the US but also a lot of people in other markets, including Norway, where the courts have sided with users. A representative of the US electric car company said that the software upgrades that users complain about are important, in order to “protect the battery pack as well as improve its usage life”. It is known that after the court ruling in Norway, Tesla will have a few weeks to appeal. A representative of the US electric car company said that the software upgrades that users complain about are important, in order to “protect the battery pack as well as improve its usage life”. The class-action lawsuit against Tesla in the US is still pending.

At the same time, the iPhone 13 and iPhone 13 Pro will have 3,065 mAh batteries, up from the current 2,815 mAh. The lowest priced phone in the series is the iPhone 13 mini which is expected to have a 2,406 mAh battery compared to the 2,227 mAh battery of the iPhone 12 mini. Photo: MacRumors With the iPhone, battery size is only part of the story. Another important part comes from how efficiently the phone’s chip and other components are optimized to work. The Apple A15 chip in the new iPhone is expected to have significant improvements in power management efficiency. Photo: MacRumors iPhone 12 mini, the phone with the smallest battery in the iPhone 12 series, had sales that fell short of expectations because of poor battery life. However, Apple A15 will probably solve this problem, according to MacRumors. Photo: MacRumors The larger battery could also be Apple’s solution to include some new more “battery-hungry” upgrades, such as the 120Hz ProMotion display. Compared to the current 60Hz screen, the 120Hz screen will definitely consume more battery. The 120Hz screen will most likely only be available on some high-end iPhone lines.

“After updating yesterday, my device only has 2% battery left, the case is 15%. Normally after 15 hours of not plugging in the charger, the battery in the phone is still 100%, the charging case can be low. 20%”, this user said the maximum battery capacity currently in the setting is still 100% after more than a year of use, will have to measure again. Many iPhone users report battery drain after updating to iOS 14.6. Illustration: 9to5mac. “I had the same problem on my iPhone 11. After updating to iOS 14.6, I woke up every morning and always found my iPhone drained. Yesterday, I turned off Wi-Fi, Bluetooth on my device, closed all apps and nothing The phone is fully charged at 6 pm, and the battery is exhausted at 10 am this morning even when not in use”, member userid42 reflect. On the forum MacRumors , member BR4DOKYBrazil said that not only does the battery drain faster, this person’s iPhone 12 Pro also heats up when browsing the web with Safari. Another member also reported the same situation on iPhone 12 mini after updating to iOS 14.6. “I made the mistake of not checking the Internet feedback about battery life before updating to the new iOS,” this member shared. iOS 14.6 was released about a month after iOS 14.5. On iOS 14.5, Apple has added a battery capacity re-measurement feature to the iPhone 11 series, helping the device measure the maximum battery capacity more accurately, overcoming unwanted battery drain. In some cases, re-measured results even allow a free battery replacement. Short-term battery drain after updating iOS is normal because the device needs to update Spotlight searches and clean up the system. However, iPhone users with iOS 14.6 are still constantly reporting battery drain even though this version has been released for more than a week. Currently, Apple has not yet responded to the battery drain on iOS 14.6. The company is testing iOS 14.7 with some improvements, but may release iOS 14.6.1 if it finds the cause of the battery drain and needs to be fixed soon. Users can restore factory settings to check if the device is still draining the battery. Why does Apple name Apple Watch instead of iWatch? Apple has many products such as iMac, iPod, iPhone, iPad. However, when it came to smartwatches, they broke the rules and named this product line Apple Watch.

Buy outright battery – expensive solution for invisible benefits The biggest benefit of buying outright batteries is not in the material value but in the spiritual value. It’s a feeling of ownership. But to get that intangible benefit, customers will have to trade it with a relatively large financial burden. The battery is by far the most expensive component of an electric vehicle, accounting for about 30-40% of the cost, according to UK-based research and consulting firm GlobalData. In the foggy country, most electric cars are still at least $13,000 more expensive than a comparable internal combustion engine car. “The biggest barrier to owning an electric car is cost,” Rod Dennis of RAC, the UK’s leading car service, told The Guardian. Although there has been a “revolution” in battery production costs, falling from $1,000/kWh in 2010 to about $150-200/kWh in 2020, according to James Frith, head of Energy Finance column. New Energy (NEF) of Bloomberg news agency, “for electric vehicles to be as cheap as internal combustion engine cars, the battery price must be brought back to the threshold of $100/kWh”. However, according to Bloomberg, the increase in raw material prices on a global scale can create a “bottleneck” that makes the goal of lowering the price of the “energy heart” of electric vehicles more difficult. “It is not a wise choice to spend thousands of dollars more just for the ‘feel of ownership’. Not to mention, the user will be responsible for all risks with the battery block if any, “said an automotive expert. Swap batteries – more risks, more costs To reduce costs for customers, some electric car manufacturers offer a battery swap policy to separate the battery from the price of the car. Specifically, instead of buying outright, customers will rent the battery pack from the manufacturer or a 3rd party. When the battery is almost depleted, the customer will bring the car to the service workshop to replace the fully charged battery. In August 2020, NIO launched a BaaS (Battery as a Service) battery exchange service with a subscription fee from 980 yuan / month (150 USD). According to “Tesla of China”, the BaaS service helps the company reduce the price of cars by about 70,000 yuan (more than $10,000). For customers, refueling the car also becomes as quick as refueling. However, every coin has two sides, the battery swap policy also shows many inadequacies. Before NIO, the battery swap model was tested in the French and Taiwanese markets, but was not really successful. In 2019, French car company Renault had to stop this policy. “Battery swapping will be more suitable for two and three-wheeled vehicles, using low voltage, usually 48V, and small battery capacity, from 1.5kWh to up to 4kWh”, said CV Raman – Head of Engineering of the company. Maruti Suzuki India, analysis. Raman also said that this is the reason why Maruti Suzuki did not enter the electric car battery swap business. “Car batteries use high voltage, are integrated with many technologies and involve the cooling system. Frequent swapping compromises integrity, creates insecurity and increases the risks associated with electrical contact,” he said. On the other hand, Omprakash Upadhyay, an electric vehicle expert at TATA AutoComp (India), said that swapping batteries does not completely reduce the cost burden for customers. This model requires large, complex and expensive infrastructure as service shops have to keep a large stock of pre-charged batteries at all times. “Invisible medium, each car must have at least two sets of batteries – one set inside the vehicle and one available in the battery replacement station. This increases the cost of the car a lot, given the fact that the battery is the most expensive component in an electric vehicle,” Upadhyay said. Battery subscription – optimal for economy, maximum for safety The battery subscription policy that some companies like VinFast apply can be considered a perfect solution, helping to balance both the advantages and limitations of the two forms of outright purchase and swap. In economic terms, instead of having to spend “a lump” of thousands of dollars to buy batteries, customers will be leased batteries by manufacturers. The monthly subscription fee is offered by the company based on the calculation of the average distance traveled. With the VF e34 model, VinFast applies a subscription fee of 1.45 million VND/month for a distance of 1,400km, meeting the average travel demand well. “Operating costs, including battery rental and electric charging, are equal to the cost of gasoline consumption, and the price and features are superior to gasoline cars,” said Ms. Thai Thi Thanh Hai – General Director of VinFast. . According to estimates by GlobalData, the cost of buying a battery pack is equivalent to the total subscription fee for more than 8 years. The form of “split” cost over time is currently quite popular with technology products and services such as phone, television or Internet packages. In particular, the indispensable advantage of the subscription form is that the manufacturer will be responsible for the battery throughout the product life cycle, even to the recycling stage, bringing absolute peace of mind and peace to customers. row. Like VinFast, the company is committed to replacing customers with a new battery pack when the battery’s ability to receive charge drops below 70%. This is a “super benefit” that customers who buy the battery outright do not get. “Battery rental helps car owners benefit more when the battery is checked, maintained and serviced in a timely manner by the manufacturer. This model will be the key for electric vehicles to develop on a large scale, “said GlobalData.

Using the bracelet to manage people in Covid-19 isolation. Emphasizing that the need for isolation monitoring in Vietnam is very large and urgent, the Ministry of Information and Communications pointed out that it is necessary to soon introduce digital technology solutions to implement automatic monitoring, improve monitoring efficiency, and reduce the load on staff. isolation areas and functional forces. In the world, there are a number of countries that have exported solutions to monitor quarantined subjects. But the Ministry of Information and Communications believes that using available foreign solutions will lead to many limitations in mastering and customizing to suit the Vietnamese context. Buying foreign solutions is also dependent on the production capacity of partners, which can significantly affect Vietnam’s Covid-19 prevention and control plan. Through the survey, Vietnamese enterprises now also have solutions (owning technology and data stored in Vietnam) and sufficient production capacity, ready to deploy on a large scale in a short time. Proposing an option to apply a dedicated bracelet to manage people, the Ministry of Information and Communications said that this device uses GPS technology to record locations, the battery runs for 30 days, has Can send an alert if vandalism is detected or out of the quarantine area. The Ministry of Information and Communications proposed that the National Steering Committee on Covid-19 Prevention and Control assign the Ministry to assume the prime responsibility for, and direct a number of domestic enterprises to research, produce and test using the socialization budget. It is expected that the time to research and customize the product to suit the requirements and mass production in large quantities is about 4 weeks after the technical plan and policy is approved. Currently, the solution of using specialized bracelets in the prevention of Covid-19 has been applied by a number of countries and territories around the world. The two main functions of the dedicated bracelet are: Proximity detection based on Bluetooth low energy technology (with the same operating mechanism as tracing applications); Compliance checking of subjects undergoing mandatory medical isolation based on GPS positioning technology. The use of a dedicated bracelet will overcome some disadvantages such as: Users do not have or cannot use smartphones, users actively turn off Bluetooth or GPS, users do not carry smartphones with them or turn off smartphones. Depending on the needs and methods of epidemic prevention and control of each country and territory, the use of bracelets with either or both of the above technologies is prescribed. For example, Singapore has put into use both close contact detection equipment and equipment to support mandatory isolation monitoring.

Founder and CEO of Dat Bike – Nguyen Ba Canh Son. To realize his start-up plan, Son spent a year in the US learning about manufacturing, from mechanics, electronics, to circuit design, industrial design, supply chain… Also in the same period of time. During this time, Son gathered a team of like-minded young engineers, learning how to make an electric motorcycle in the US. This is an important stepping stone for Son’s project formation and development in Vietnam. Founder and CEO of Dat Bike – Nguyen Ba Canh Son, said: “This capital will be used to improve the quality of the bike, perfect the sales team and expand the market.” In particular, improving the quality of the battery and controller will be put on top by Dat Bike. It is known that Dat Bike was established in 2018 with the ambition to become the largest electric motorcycle company in Southeast Asia. In the Vietnamese market, Dat Bike is having an estimated growth rate of 30%. Dat Bike’s first motorcycle model was launched in Vietnam in 2019 from the factory located in Binh Duong, called Weaver. The advantage of this model, which is also the difference with electric cars currently on the market, lies in its long travel time and fast battery charging. The battery installed in the Weaver uses LG’s technology, similar to the battery system installed in Tesla electric cars. In particular, the battery life is up to 10 years in conditions of regular use and is easy to recycle, with no adverse impact on the environment. Compared to other competitors, Dat Bike has the advantage of using domestic materials, instead of importing from other markets. This helps the company reduce transportation costs, increase production efficiency and receive tax support. Currently, Dat Bike has a shop in Ho Chi Minh City. Ho Chi Minh. Currently, Dat Bike has a shop in Ho Chi Minh City. Ho Chi Minh City and a factory in Binh Duong with a capacity of about 1,000 vehicles/month. The company has only focused on developing online sales channels in the Vietnamese market. In addition, another advantage of Dat Bike is that the company’s vehicles are manufactured in the country, most of the component suppliers are local manufacturers. Therefore, the Company can be proactive in logistics and supply chain services. In just a short time, Son and his team of associates have increased the production capacity of Dat Bike from 1 motorcycle shipped per week in the early days to hundreds of units per month. At the end of 2020, Dat Bike opened its first store in Ho Chi Minh City and currently, Dat Bike’s growth rate is 35%/month. In particular, in 2020, the Ministry of Transport has recognized Dat Bike Weaver as the first electric motorcycle originating in Vietnam. This is also the only model on the market today that has the same performance as a traditional petrol motorbike. Jungle Ventures is a Singapore-based venture capital firm that focuses on investing in early-to-growth businesses and start-ups in Southeast Asia and India. With a focus on building sustainable businesses, Jungle Ventures has been working with the region’s most ambitious founders to build high-growth technology businesses, using capital-efficient, with the potential to scale into leading regional or global companies. The $2.6 million capital “poured” from Jungle Ventures and investment funds allows Son and his associates to continue to create and develop the most complete electric motorcycles for users in the Southeast region. Asia and the world through investment in expanding production of Electric Vehicle Factory in Binh Duong. CEO Dat Bike calculates, with more than 80% of households in Indonesia, Malaysia, Thailand and Vietnam owning two-wheeled motorbikes, a total of about 250 million gasoline motorbikes, the size of the motorcycle industry in Southeast Asia. up to $25 billion. These potential numbers are the motivation for Son and Dat Bike team to continue firmly on the chosen path, contributing to promoting wider use of sustainable transportation solutions. Soon, Dat Bike will release the next version of Weaver. This version is capable of running 200 km, fully charged in 2 hours. In the further future, Dat Bike will develop more new models to suit a wide range of customers.

The images on the patent show a phone with a triple camera module at the back, with the top camera able to rotate between front and back positions. When in selfie mode, the camera will turn inward and the display area around the camera will be disabled so that light can reach the sensor. A magnetic or mechanical mechanism will help rotate the camera. Realme launched a smartphone with 5,000 mAh battery, 33W charging, 90Hz screen, 6 GB RAM, priced at more than 4 million VND This design will bring a number of advantages over the product. The first thing to know is that it will enhance the quality of selfies. The selfie camera is rarely on par with the rear camera when it comes to imaging performance, not to mention that the under-display camera can be at an even greater disadvantage than the traditional selfie camera. By rotating the main camera from the rear module, Xiaomi can improve the performance of the selfie camera without paying extra for a better selfie camera. Taking advantage of the rear camera not only saves money on buying a high-end camera sensor, but it can also help utilize the space inside to increase battery capacity. Waterproof smartphone, S888 chip, 12 GB RAM, 240Hz screen, 2,000 nits brightness However, it also leads to a few downsides. A rotating camera will also need additional components for it to rotate, so it will lead to a waste of battery space. Rotating the lens inside the phone can have an additional side effect that the camera part may have to be even thicker to be able to rotate the lens – which was already thick. Detailed photos of Asus ZenFone 8 Flip: ‘super terrible’ configuration, 5,000 mAh battery, 90Hz screen, rotating camera, priced at more than 22 million Xiaomi’s invention idea. Finally, some glitches with the rotating camera can also occur. A flip camera with moving parts can always be damaged and that is the main concern when sliding camera systems in the past have always had certain problems. As everything happens inside the phone, it means that if there is debris happening inside the mechanism, it will force deep intervention into the hardware. See the waterproof smartphone, the world’s best screen, S888 chip, 12 GB RAM, ‘super big’ camera Like other patented technologies, it is unclear if Xiaomi will put this technology into actual products. In fact, Apple has also researched a mirror system that illuminates from the front and rear cameras into the same sensor through a patent in 2015, but this mechanism has not been implemented by Apple so far. on its products.

This time started in the summer, the demand for cooling devices increased, leading to a dizzying increase in electricity bills, so solar fan models were sold on the market. They are advertised, instead of running on electricity like conventional types, this type of fan operates entirely on solar power. Specifically, each solar fan will come with a solar panel to help absorb sunlight and produce electricity to maintain operation. Depending on the type of panel, when placed in the sun, the fan controller will charge the battery, which takes 4-6 hours. After the battery is fully charged, the fan will work for 6-10 hours continuously, even on rainy days without sunshine. In addition, users can use grid electricity to charge the battery for storage and use. Solar fans are causing fever in the market this summer Currently, on the market, these fans come from many places such as: China, Korea, Vietnam, … with very diverse prices, depending on size and function. In which, the lowest price is about 200,000-300,000 VND (mini fan), tree fan costs 800,000-2 million VND. Many fan lines are being discounted by 20-50% to attract buyers. For example, the 20W mini solar fan line is being discounted by up to 50%, from VND 830,000 to VND 417,000; mini fan 3.5W X9E is 40% off, from 510,000 VND to 306,000 VND; The Sunisi FT-30 fan model is priced at 1 million VND, 50% less than the original price of 2.1 million VND; Korichi KRC 6300 fan model reduced from 1.2 million VND to 890,000 VND; Jenpect 220V fan model has the original price of 1.3 million VND, down 34%, now only 850,000 VND,… According to the advertisement of the staff of household electrical stores, compared to traditional fans, solar fans have many advantages such as: no electricity costs, no fear of sudden power outages in hot summer days. Not only that, they are also very convenient when going on a picnic or camping trip; can directly charge other mobile devices such as phones, flashlights, … via USB port, which is very convenient. Moreover, long battery life 3-5 years of use, battery capacity up to 12,000 mAh, using time up to 8-12 hours. With “divine” functions, especially without consuming electricity, this type of solar fan immediately caused a fever in the market and was sought after by many people. Mr. Nguyen Hung – an employee of an electronics store in Ho Chi Minh City – said that at this point, the demand for cooling fans has begun to increase sharply, in which the solar fan line is the best-selling model. . As at the beginning of summer, his shop sold about 300 solar fans, at the peak of last year’s heat, he sold up to 800 units. Many fan models are having super cheap prices to attract buyers Similarly, Mr. Hoang Van Binh – an employee of an electrical appliance store in Thanh Xuan (Hanoi) – also said that in recent years, the price of electricity has tended to increase, people have the need to buy and use electricity. Use energy-saving appliances and take advantage of natural energy sources. Therefore, from May, customers looking to buy solar fans are busier. Currently, he only has 15 more fans to sell out. According to him, this type of fan is often suitable for low-rise houses, level 4 houses rather than high-rise buildings and apartments like in the city. Because the fan and solar panels are separate, it is necessary to choose a location to mount the panels to catch the sun (roof, rooftop, balcony, front yard, …) then connect to the fan set. Therefore, with high-rise buildings, moving equipment is quite difficult. But Binh also admitted, when it rains, the charging capacity of the fan will be poor, so in the prolonged rainy season solar fans will not be able to promote their full benefits. At that time, the fan can still be used by the grid as usual. Talk to PV. VietNamNet, Mr. Le Van Kien – a technical staff member of an electrical appliance store in Khuat Duy Tien (Thanh Xuan, Hanoi) – shared, when buying a solar fan, it is necessary to pay attention to the lifespan of the panels. The origin of the battery is unclear, poor quality will make the fan’s performance worse, the fan runs erratically, the lifespan is reduced, and it pollutes the environment. Moreover, the life of the battery is usually only 2-3 years, then it has to be replaced at a considerable cost. In addition, the capacity of the battery will determine the operating time of the fan, the battery is designed with a high capacity, the better the charge will be and vice versa. Limit the selection of multi-function rechargeable fans that are equipped with lights, alarms or clocks… because these features consume power from large batteries, making it easier for the battery to fail faster. Users should not be greedy, but buying low-quality fans will have many potential risks, so consider when choosing and need to choose to buy products of reputable brands and addresses.

I’m a pretty neat person. Furniture when going home like backpack, glasses, keys or wallet are stored in the correct tray in a box next to the door. Thanks to that, I rarely have to look for things that are important to me before going to work. However, no matter how neat I am, there are times when I lose my belongings. I dropped the wallet on an acquaintance’s car, and because the wallet fell into the slot under the seat, my friend couldn’t find it. Had it not been found by the car washer, I might have had to go over and over again. These are situations where a misplaced device like the AirTag comes in very handy. I was very excited when Apple introduced the AirTag, but it still has many inconveniences when it comes to real-world experience. Accessories “cheap” in the Apple way Excluding EarPods or chargers, AirTags is Apple’s cheapest standalone product. This accessory has a genuine price of about 800,000 VND, and if you buy a set of 4, the price is a bit lower. However, for many this will not be the final price to be able to use AirTag. The device has a round design and two sides are not flat, meaning it is difficult to secure in the compartment of a handbag. Leaving AirTag in your wallet just makes your wallet look good, while lowering your device’s notification volume. AirTag is also quite thick, so placing it inside thin wallets will make the wallet look up quite a lot. In addition, if the AirTag is placed in the wallet or compartment too thin, the efficiency will also decrease. The solution now is to buy a leather pouch. Although there are no prices in Vietnam, the genuine bags that Apple sells are priced equal to or several times higher than the AirTag itself (from 29-449 USD). Leather cases of craft units in Vietnam also cost about 200,000 VND or more. If you buy this accessory, the price of AirTag will be nearly 1 million dong. AirTag pairs very quickly with iPhone. Due to not being able to buy a holster in time, I used the “bare” AirTag, and immediately understood why a holster was needed. In less than a day of use, leaving this accessory in the backpack and wallet compartment, both the aluminum and plastic sides of AirTag have had scratches. Actually scratches will not affect the function of the device, but for those who require high looks, these are still the points to pay attention to. Well done the main function Connecting AirTag to iPhone is very simple. Just bring the accessory close, the machine will automatically recognize and the set-up takes only about 30 seconds. This is a big plus compared to other finder devices. To find items attached to AirTag, users have 3 ways. First, they can go to the Find My app, choose to show up on the map to see the last recorded location. If you are in the same apartment, you can press the speaker button to let the AirTag play the sound. The third method only applies to iPhone 11 onwards, allowing the display of the direction and distance to the nearby AirTag. The “exact find” function worked quite well, but still occasionally lost the signal. The Find My network with billions of devices running iOS is a huge advantage of AirTag. No need GPS or network connection, users can still find the AirTag when it is near any iOS device. Testing in city conditions, I found the position of AirTag on the map was quite accurate. The challenge will come when you want to find the AirTag nearby. The AirTag’s “speaker” is in fact the white plastic side of this device. When you select a sound feature, the plastic face vibrates to create sound. This sound is only enough to be heard in an apartment, when the background noise is quite small. If you search inside a multi-storey house, or assume your family member has the TV turned on quite loudly, you will be hard pressed to hear AirTag’s sound. This is why you should not leave AirTag inside your wallet too tight. At that time, the volume of AirTag emitted will be much smaller, reducing the efficiency when searching. The search when the AirTag is lost is quite effective, the address is accurate. The UWB wave precision search is also useful, but efficiency depends on the environment. When I tried to leave AirTag in the living room of a 2 bedroom apartment, the iPhone frequently reported “weak signal” when I went into one of the bedrooms. Only when the distance is less than 4 m, and there is no barrier between the iPhone and the AirTag, can the device be able to accurately indicate the distance and direction. Combining all 3 of these features, the ability to find lost items will increase significantly when attached to AirTag. However, there are still environments where AirTag is not very efficient, like in a large apartment, or in the middle of a crowded shopping mall. It is also not suitable if you want to leave it on your motorbike to look in the parking lot, as cheaper and louder accessories are available on the market. It would be disastrous if used the wrong way At launch, Apple stated that the AirTag was an accessory “to track things, not to track people”. The company also integrates a number of features so that users know when someone else’s AirTag comes with them. However, in practice these features all have vulnerabilities. The current AirTag can still be used to spy on others. The first way AirTag notices is sound. According to Apple, after “a while”, if an AirTag is separated from its host device, it will squeal to get attention. The company did not specify how long that period was. Just squeeze or stick the tape around the AirTag and the sound will be very soft. According to the Washington Post , it took three days since the last time away from the owner, the AirTag cried for about 15 seconds, and then rang every few hours. The 3-day period is quite a long time for AirTag owners to keep track of the places the victims visit. Besides, reducing the sound of an AirTag is not difficult. If you detect an AirTag that is not with the same account but has been nearby for a long time, the user’s iOS device will also pop up a message saying there is a strange AirTag. The victim can press play to find the strange AirTag, but cannot access the map or find the exact same as the official AirTag. However, in my hands-on experience carrying the strange AirTag all day, I never get a notification on my iPhone. Also, if the victim uses an Android phone, they won’t receive any notifications. AirTag uses the familiar CR2032 battery, sold in every watch shop. AirTag still has many vulnerabilities to be misused. That’s not to mention if the AirTag owner is spying on a relative and knows their iPhone’s password, that person can go into the Find My app and turn off notification when it detects a strange AirTag. Although Apple promises very well, AirTag can still be used as a tracking device for others. In the future, the company may update to reduce the alarm interval or adjust the notification feature. At present, AirTag still has many major vulnerabilities that can be exploited for the wrong purpose. Should I buy AirTag? If you are an iPhone user and forgetful, AirTag will be a very useful accessory, especially with important objects. The price of nearly 1 million is not high compared to the effort of redoing papers in your wallet, or hitting a car key. AirTag can be said to be a huge reason iPhone users continue to stick with Apple’s ecosystem. However, if you do not use an iPhone, there are many other options on the market, with prices as low as half the Samsung SmartTag or Baseus Intelligent T3.

Wallpaper set has 6 different designs, sold on the author’s website for about 6 USD for 2 designs. The wallpaper above is inspired by the Apple Face ID icon. When the battery is full, the wallpaper will be a smiling face with blue rings around. Conversely, tired face with red ring will appear when the battery is below 20%. In the charge state, the wallpaper becomes an unexpected face with golden rays of electricity. The first set of wallpapers with 3 shades designed by Ben Vessey. Ben Vessey also designed an apple-shaped wallpaper. Wallpaper will show apple (intact, not bitten in half) when full battery and apple core shape when battery is depleted, simple smiley face is between 20% – 100% battery and a frown face with battery short. All designs are very simple and easy to understand. Ben Vessey shared, the design of 6 smart wallpapers helps solve two main problems. One is that in case the user plugs the charger cord incorrectly so the phone will not recognize the battery, then with smart wallpaper, users will easily detect it. The second problem is that smart wallpapers will report low battery status. “When using the phone, our subconscious mind often ignores the low battery warning of the device. My designs will help users avoid that situation, ”shared Ben Vessey. The second set of backgrounds are highlighted with apples. Previously, according to predictions from some technology experts, the new-generation iPhone products can be equipped with Pro Motion technology, 120 Hz refresh rate and 15-20% lower power consumption than iPhone 12. Specifically, the iPhone 13 Pro and 13 Pro Max models will be equipped with LTPO energy-saving screen technology. This screen technology has appeared on the Galaxy S21 Ultra and Oppo Find X3 Pro. The LTPO display can automatically adjust the scan frequency based on the content being played. For example, when the user is playing games or watching action movies, the screen will increase the refresh rate to 120 Hz. When the user is not in use, the screen of the machine will automatically reduce the scanning frequency to lower, helping to save battery power. According to some leaked sources, Samsung and LG Display are in the process of converting production from LTPS to LTPO screens, which could be completed in the first half of 2021. However, there are opinions that capacity to make LTPO screens lower than LTPS because companies have to add some manufacturing processes.

According to Apple’s release notes, the update provides an important security patch, which fixes two major vulnerabilities in the WebKit suite of apps that could allow hackers to break into a user’s iPhone. Apple recommends that users update immediately to iOS 14.5.1 as soon as possible. (Photo: iOS News And More) However, the recent version of iOS 14.5.1 that Apple released recently seems to continue to bring other troubles for iPhone users. Specifically, in a thread created by Reddit user LHG_93, this person complained about the battery life on his iPhone getting worse after updating iOS 14.5.1, even installing Resetting the device also couldn’t help. “Has anyone noticed that the battery life of the device is very poor after the iOS 14.5.1 update. Even reinstalling is not helping,” said LHG_93. (Screenshots) Below the thread created by LHG_93, many members on Reddit also said they are experiencing the same situation after updating to iOS 14.5.1. “I have, too, the iOS 14.5 update is better than iOS 14.5.1”, said member DRS-MICKY. “I also noticed the same thing. I’m using an iPhone 12 Pro”, according to member zangielv. “Using an iPhone 7 and also the same as the OP,” shared member PaulF1959. (Photo: iPadizate) “It’s hard to understand how, after 8 beta versions of 14.5 and then 14.5.1, battery drain continues to be an issue on iOS 14 … I also saw a lot of battery drain on iOS 14.5. first. I don’t understand why Apple didn’t fix this. My device isn’t even that old, it’s the iPhone XR. IOS versions 13.5-13.7 are better in terms of battery retention on the iPhone XR. After 8 beta versions, iOS 14.5 should have been much better, “said member xxGon. (Photo: ThinkApple) Not only was it complaining about battery drain, iOS 14.5.1 is also said to cause some iPhone models to have performance issues. Notably, this error seems to occur not only with older iPhone models such as iPhone 7, iPhone 11, … but also iPhone 12 Pro, iPhone 12 are also believed to have a similar situation.

Squeezing on top of a decommissioned volcano in northern Nevada, workers are preparing to blast and dig holes to mine the first large-scale lithium mine in the United States in more than a decade. According to the New York Times, Lithium is an essential ingredient in the manufacture of electric car batteries and renewable energy. This lithium mine was built on federal rental land and promises to address current US dependence on international lithium supplies. However, this Lithium Americas project was strongly opposed by members of the Native American tribe, the owner of the farm and the environmental groups. The project plans to use billions of gallons of groundwater in the area. In addition, the lithium mine has the potential to pollute for up to 300 years and leave severe consequences and huge waste of waste. The conflict surrounding the Nevada mine represents a new tense problem: Electric cars and renewables may not be as green as they seem. “Blowing a mountain is not environmentally friendly, no matter how much economic expectations people put on it,” said Max Wilbert, who lives at the proposed mine. Demand soared In addition to Nevada, private businesses are proposing other lithium mining sites in California, Oregon, Tennessee, Arkansas and North Carolina. According to the Bloomberg In the first three months of 2021 alone, lithium miners in the US raised nearly $ 3.5 billion from Wall Street, seven times the amount raised in the previous 36 months. This shows that a lithium boom is exploding as the electric car industry is becoming a new trend. Lithium is used in electric car batteries because it is light, stores a lot of energy and can be recharged many times. Analysts estimate demand for lithium will increase tenfold as Tesla, Volkswagen, General Motors and other automakers launch a series of new electric cars. Blasting a mountain is not environmentally friendly, no matter how much economic expectations people place on it. Max Wilbert, a resident of the Lithium Americans mining area. Therefore, the US needs to quickly find sources of lithium when electric car manufacturers accelerate production. Although the United States has the largest lithium reserves in the world, the country has only one large-scale lithium mine, the Silver Peak mine in Nevada. Mining started in the 1960s and produces only 5,000 tons / year – less than 2% of the world’s annual supply. Most of the raw lithium used in the United States comes from Latin America or Australia, which is then processed and manufactured into batteries in China and other Asian countries. The Lithium Americas mine under construction in Nevada is estimated to have a lithium value worth $ 3.9 billion. The operator is expected to start mining operations next year. The largest shareholder of the mine is Chinese company Ganfeng Lithium. However, traditional mining is one of the most “dirty” businesses today. For electric car manufacturers and renewable energy companies, this situation has not improved much. “While its intentions are good, the need for clean energy can do harm,” said Aimee Boulanger, executive director at mining services for BMW and Ford Motor. bigger”. “Dirty” industry On a hillside, Edward Bartell and the ranchers often go out early in the morning to make sure that 500 cows roam the 50,000-acre (202 km2) desert with enough food. Faced with a lithium mining project in the area, his family has never faced such a great threat. Not far from Bartell’s farm, the largest lithium Americans project in the United States is on the horizon. Mining ore will have helipads, chemical treatment plants and waste yards with the depth of the mine up to 112 m. Traditional mines are potentially dangerous to the environment, animals and people living in the area. Photo: NYT. Producing raw materials such as lithium, cobalt and nickel often harm the soil, water resources, wildlife and people in the area. Like the competition for gold and oil in the past, governments are taking advantage of minerals to gain future economic and technological dominance. However, in the economic and technological race between great powers, environmental issues are often forgotten. What Barbell was most worried about was that the mine would consume all the water of the cattle. The mining company said the mine would consume 3,224 gallons of water per minute (equivalent to 12,204 liters / min). Thus, the groundwater level in the land where Mr. Bartell is breeding could decrease by about 3.5m. In addition, if the mine targets to produce 66,000 tons of lithium carbonate per year, this mine could cause groundwater to be contaminated with antimony metals and arsenic. Lithium is extracted by mixing clay dug from a mountain slope with 5,800 tons of sulfuric acid per day. The documents show that the entire process produces 354 million cubic meters of waste extracted from sulfuric acid treatment and can contain radioactive uranium. A December assessment by the Ministry of the Interior found that over its 41-year lifespan, the lithium mine would damage nearly 20 square kilometers of antelope and wildfowl habitat. In addition, the mine will destroy the nesting area of ​​a breed of golden eagle and other wildlife. “It was disappointing that the lithium mine was introduced as an environmentally friendly project, when in fact it was just a giant industrial park,” said Mr. Bartell. He filed a lawsuit demanding to stop mining activities. “The war is not fair” So far, the Joe Biden administration has not moved to promote more eco-friendly strategies such as extracting lithium from sea salt water instead of opencast mining. People of ethnic minorities protest outside the land management office to protest against the Lithium Americans mining project. Photo: NYT. Mining companies, meanwhile, want to speed up domestic lithium production and push the government to include a $ 10 billion funding program in the infrastructure bill. “If China severs relations with us, the US will face many difficulties,” said Ben Steinberg, an official in the Obama administration, threatened. This war is inherently unfair. After all, the mining units are just capitalists. Maxine Redstar, the leader of Fort McDermitt Paiute and the Shoshone tribe. At the Fort McDermitt Indian Reserve, controversy over the project was even more acute and led to more conflicts. The Lithium Americas mine proposes to hire tribal members as workers with an average salary of $ 62,675 / year. This salary is double the per capita income in the region, but indigenous Indians will pay a huge price for the environment and nature. “After you pollute the water here, what will we drink in the next 300 years? You’re lying!” Said Deland Hinkey, a member of the indignant tribe. Mr. Tim Crowley, vice president of Lithium Americas, pledged that the company will operate responsibly with the local environment, planning to use steam from burning molten sulfur to generate electricity, for example. However, people here still do not trust and fear that mining activities will cause serious environmental consequences. “This war is inherently unfair. After all, the mining units are just big capitalist corporations,” said Maxine Redstar, leader of Fort McDermitt Paiute and the Shoshone tribe.

Initially Leafy house The activity was planned to be carried out in two weekends (April 17-18), but the battery collected in just 2 days has exceeded expectations and still many people have yet to participate. Therefore, the project is extended by young people from April 19 to 25. Young people bring used batteries to the Leafy House in exchange for green trees Hoang Ai Nghi (in charge of the program “Exchanging batteries for trees”) said, as of the afternoon of April 24 (on the 8th day – PV), the program has received a series of batteries, including: primary batteries , phone battery, laptop, rechargeable battery … For every 5 pieces / battery given away, you will receive 1 green tree, a small stone lotus or cactus. “Over the past few days, we have welcomed many people to send batteries and take back trees. Tracking and knowing about the program through fanpage or sharing from friends, students, employees, parents or even children bring batteries to support the program ”, Ai Nghi shared. The activity of “exchanging batteries for trees” actively contributes to the transmission of the message of green living and environmental protection You volunteers join hands in the program In addition to the activity of “exchanging batteries for trees”, Many Leaf Houses also sell green products and recycled products By the end of April 24, the program had received more than 120,000 broken batteries and electronic equipment; donating 6,000 trees. The collected batteries will be sent to the gathering point of Vietnam for recycling to be disposed of most thoroughly. It is known that each battery thrown into the environment or improperly disposed of will contaminate 1 cubic meter of soil and 500 liters of water within 50 years. Once received, these batteries will be volunteered by volunteers Leafy house bring to the gathering point of the Vietnam recycling program for the most thorough treatment. On the same occasion (April 24 and 25), Leafy house also organized the activity “Exchange plastic bottles for recycling socks” to receive more recyclable materials. “Many Leaf Houses” known as a chain of social activities in terms of culture, education and environment, has been deployed in Hanoi City and recently Ho Chi Minh City. Next to the activity “Change batteries for trees”, Leafy house also received plastic bottles and paper, implemented a free book library in the form of “lending books by trust”, sold trees to raise funds …

Term 2: Solve the quality management problem, electric vehicle regulations Electric vehicle charging station at AEON Ha Dong Shopping Center (Hanoi) – photo by Thanh Tung With more than 1 million electric scooters in circulation and thousands of electric cars handed over to customers by VinFast by the end of this year, the problem of quality management, registration, and charging station standards comes from The legal regulations in the circulation of vehicles for electric vehicles are in urgent need. Register like a traditional car At the end of March 2021, VinFast’s electric bus model was completed by the Vietnam Registry Department to verify design documents, vehicle safety testing and met the conditions of current automotive technical regulations. onions for mass production. Recently, VinFast has also announced to receive orders, produce an electric car model under 9 seats under the brand name VF e34, expected to hand over the car to customers in November 2021. In fact, electric cars have appeared in the country a few years ago and now there are 14 cars (all imported complete units, the Tesla brand). With the above trend, in the near future, the domestic market will have both imported CBU electric cars and domestically produced cars. Mr. Nguyen Van Phuong, Deputy Department of Motor Vehicle Quality – VAQ (Vietnam Registry Department), said that electric vehicles are quality controlled from the evaluation of vehicle design, safety testing to issue type certificates. and sample production. After the car is released, the circulation process, electric cars must be periodically registered as traditional cars. According to Mr. Dang Tran Khanh, Deputy Department of Motor Vehicle Inspection – VAR (Vietnam Registry Department), the biggest difference between electric cars and gasoline and oil cars is the energy source for the vehicle’s engine to operate. Therefore, the registry will apply the inspection of technical safety items according to the current national automotive technical regulations, except for the exhaust gas test, which will not be the same as gasoline or oil vehicles. “Currently, some countries like Singapore also test electric cars like conventional cars. However, the Vietnam Registry Department is consulting the experiences of countries and international automobile registration associations to take steps to research and prepare for the process of supplementing and completing the standards of cars, including cars. electricity ”, said Mr. Khanh. Which standard charging station? According to a recent study by the Research Group of the German International Cooperation Organization (GIZ), it is currently the beginning stage of the development of electric transportation in Vietnam. Imported electric vehicles including bicycles, electric scooters and four-wheeled passenger electric vehicles currently have more than 1 million vehicles. It is expected that by the end of 2021, there will be only electric cars produced domestically. About the current regulations applicable to electric cars, the representative of the Motor Vehicle Testing Center (Vietnam Registry Department) said that in-depth techniques for electric cars are electrical elements. There are a number of different research and development trends in the world. ” Electric car is still a manned car like a conventional internal combustion engine, so when the car is put into operation at present, there are no legal problems. Electric vehicle drivers, while participating in traffic in Vietnam, still comply with the current Decree 100 and the Law on Road Traffic
Decree 100 deals with the driver’s behavior more than the vehicle. And the current Law on Road Vehicle has regulations on vehicles, but in road motor vehicles, there is no regulation on engines. Therefore, the legal basis for electric vehicles is basically the same as conventional gasoline and oil vehicles, including procedures for vehicle registration and vehicle registration.
Mr. Khuat Viet Hung, Specialized Vice President of National Traffic Safety Committee ” Such as the standard of charging. Therefore, in this early stage, mainly based on the National Technical Regulation on technical safety quality and environmental protection for cars (QVN 09: 2015 / BGTVT) to test and evaluate. vehicle safety prices. At the same time, there is research to build appropriate standards for the development of electric cars in the country in the future. According to Mr. Nguyen Van Khoi, Director of the Department of Standards (General Department of Standards, Metrology and Quality), Vietnam currently has the standard TCVN 12241-3: 2018 on the secondary lithium-ion battery used for power transmission. for electric road vehicles. This International Standard specifies test procedures and acceptance criteria for the safety performance of batteries and masses of secondary lithium-ion batteries used to power road vehicles (EV). including battery electric vehicles (BEV) and hybrid electric vehicles (HEV). “However, we do not have a set of standards (required to apply) on charging stations and charging terminals. This is not even available in advanced countries. Just like the plug of household electrical appliances has not been agreed, where the power supply is 110V, where 220V, the device has a 3-pin or 2-pin plug, but the 2-pin plug is also each style. In addition, the structure of the electric vehicle charging station is also a technology secret issue, so no company wants to share it, so it has not been agreed to set which one is the standard. For example, the phone charger, until now it has been agreed, to buy any device, use the charger cord, the charger of that company, basically according to the original equipment manufacturer “, Mr. Khoi said. Just as a car powered by an internal combustion engine needs multiple gas stations, an electric vehicle (EV) also needs multiple public charging stations. The question is which technology standard charging station will Vietnam follow in order to be able to meet the maximum number of electric vehicles with different charging standards? According to Mr. Dao Cong Quyet, Head of the Public Relations Subcommittee of VAMA, there are currently 3 international charging standards for cars, including: Europe (CCS), Japan (CHAdeMO) and China (GB / T). ). If there are many electric car manufacturers, it is also necessary to have a common standard for the car manufacturers to plan to manufacture and import this type of vehicle for sale in Vietnam. Mr. Tran Quang Ha, Deputy Director of the Department of Science and Technology (Ministry of Transport), said that the charging standards of many basic companies according to Europe, but most of them do not have the uniformity of the common charging standard between the companies. Currently, road motor vehicles in Vietnam are basically all according to European standards. On the issue of waste disposal for electric vehicles, Mr. Ha informed that most countries have strict and strict regulations on waste product management. As for the discarded products containing harmful substances such as batteries and batteries, Vietnam has also had regulations but there are no sanctions. “When electric vehicles thrive, the problem of completing regulations on waste management and treatment such as batteries, batteries will be very hot. There should be clear sanctions “, Mr. Ha suggested.

People are excited to buy clean agricultural products. On April 25, in Da Nang, many people and tourists were excited to visit and shop at The Good Market – an event organized by HealthyFarm – a social enterprise in Da Nang.

Professional solar battery cleaning worker for a project in the city. Ho Chi Minh Meanwhile, according to engineer Thanh, the current method of cleaning the panels is mostly done by investors, most of them are using water, available facilities and using a hose to wash them, this method is not technically correct. in terms of maintenance, because many areas have water contaminated with alum, hard water, there is a lot of organic matter, more dissolved metals… leading to further damage to the panels. “The effectiveness of the project apart from equipment, materials, installation techniques, the operation and maintaining the efficiency of the system is related to the cleaning of the panels. Keeping the panels clean is the key to maximizing output, increasing economic efficiency for investors, ”Thanh said. Solar power is booming in Vietnam, especially household investment packages, concentrated in remote and island areas in the South. According to the Vietnam Electricity (EVN), by the end of 2020, the total capacity of renewable energy sources will be 17,430 MW (up 11,780 MW compared to 2019) and accounting for 25.3%. . In which, there are about 8,000 MW of rooftop solar power and more than 8,400 MW of large farm solar power. Thus, according to investors’ calculations, the whole country currently has no less than 30 million solar panels operating in the whole system and will increase when many projects are under construction and about to be operational. Seeing this potential, a number of businesses in the South have added new services, which are professional cleaning of solar panels and package maintenance for solar power systems. the investors. Mr. Le Tran Khanh Vy – General Director of Nhat Hung Environmental Technology Co., Ltd. (Thu Duc City) – said that in the face of more and more investors installing solar equipment, the company opened more professional solar battery cleaning service, currently hundreds of customers across the country have signed contracts to participate in cleaning and maintaining solar power systems with this package. To meet the needs of customers, especially solar power investment packages in industrial form, the company is forced to professionalize by producing standard cleaning solutions, investing in specialized cleaning equipment. and has a team of professional staff in charge. “The solution that the company offers is to keep batteries clean by cleaning them regularly and properly; Check the water source, if the water source is contaminated with alum, hard water, contains a lot of organic matter, lots of dissolved metals, it must be handled; choosing a cleaning solution specialized for cleaning panels, because now there are domestically produced products with appropriate and safe prices, ”said Mr. Vy. On the market, there are specialized solutions for cleaning solar cells According to electricity experts, at present, many solar power projects are invested billions of dong, even more money, but the stage of battery cleaning and system maintenance is less concerned by investors properly. This leads to a reduced lifespan of the building, especially the heat collection efficiency of the panels is low, while if cleaned and maintained properly, the economic efficiency is not small. Mr. Huynh Duc Tien, living in Hoc Mon district, city. Ho Chi Minh has just signed a package contract with a company specializing in solar battery cleaning and maintenance of the solar power system with an investment of more than 1.2 billion VND nearly 2 years ago. Mr. Tien said that the cleaning company has specialized solutions, tools and techniques, so it is handed over to them for management because the cost is not much and it saves time.

Apple AirTag is actually quite small and its size is only close to the bottle cap. This product has a simple front in case you didn’t choose emoji engraving for free and comes with the Apple logo on the back. “Apple Apples” has equipped AirTag with IP67 water and dust resistance so you can attach it to your pocket or even your pet without worrying about the accessory being damaged in bad weather. . Apple AirTag even has a small speaker inside so it can alert you in case you can’t find your stuff. This accessory comes with a battery life of “over a year” and users can replace it easily. The back of the AirTag is designed to be slightly protruding, where you can replace its standard coin cell battery. As Apple describes it, the AirTag setup is “miraculous”. This accessory will automatically detect your iPhone and display the same setup screen as the AirPods. You just need to name it or set a default like “Key” or “Jacket” and the AirTag tag will start showing up in the “item” section of the Find My app. Tracking accuracy AirTag uses Apple’s U1 chip, found in the iPhone 11 and iPhone 12 series, to determine the exact location. Using the Ultra WideBand technology and the U1 chip, the AirTag can accurately measure their distance from the iPhone and return the exact location. When you tap the AirTag in the Find My app, it uses input from the camera, ARKit, accelerometer, and gyroscope, then guides the user to the AirTag using a negative feedback combination. bar, touch and image. Apple has also added support for accessibility features to AirTag. For people who are blind or have low vision, the VoiceOver feature can be used, which will provide directions such as “AirTag is 9 feet left from you”. Find My Network Apple introduced its Find My Network to third-party accessory manufacturers earlier this month, and it now says “is approaching one billion of Apple’s Find My Network devices”. It is known that AirTag relies on Bluetooth and U1 chip to return location to the user. Therefore, if the accessory is detached from the user, it sends an anonymous signal to surrounding Apple devices. AirTag will then forward its own location, via the nearest Apple device, to its owner in the background, privately. Lost mode If you lose your AirTag and cannot find its location, you can put AirTag in “Lost Mode”. This will create a trigger in Apple’s Find My Network, and in the event an Apple device gets close to your AirTag, it will forward the location of this accessory (private) to your iPhone. If an AirTag is in “Lost Mode” and is found by someone, a user can simply touch the AirTag on an NFC-enabled device (not necessarily an iPhone) and it will automatically open a web page, where details will be shown such as phone number of the lost person. Accessories Apple also released a number of accessories for AirTag. This product does not have a magnetic back or designed to attach to the user’s object, so it will depend on accessories to do that. Apple says users can ditch the AirTag for a bag or purse, and it still works fine. But for objects like keys, it must be kept in a special kind of lock. Apple has released a number of first-party accessories for the device, including Polyurethane Loop, Leather Loop, Leather Key, and some special edition Hermès accessories. The Polyurethane ring costs $ 29 (around 670K), the leather key ring costs $ 35 (around 800K), and the leather bracelet costs $ 39 (about 900K). Third-party accessory manufacturers will also roll out a number of accessories for AirTag in the coming months. Easy to replace battery AirTag comes with a battery that can be easily replaced. Apple says that the AirTag will perform well for “more than a year,” after which users will have to replace its batteries. This accessory uses a standard CR2032 coin cell battery, which can be easily replaced by removing its back cover. Privacy AirTag does not store location data on the device. It only forwards a signal to the nearest Apple device, which is then used to locate the AirTag. Apple says that data is kept confidential and communication with Find My Network is end-to-end encrypted. AirTag also comes with a host of other security features.

Instead of riding his 1967 Corvette Sting Ray, US President Joe Biden took the time to take an online tour of the electric bus factory and the electric vehicle battery factory on April 20. . This is considered an important activity in his plan to boost production of electric vehicles in the future. Mr. Biden visited the electric bus factory online. (Photo: Hot Cars) From working in the White House, Mr. Biden had a live view of the production of electric buses at the Proterra factory in Greenville, South Carolina. President Biden is particularly interested in how the buses are assembled and tested and is impressed with the progress here. “Right now, we (the United States) are behind China and there is much more work to be done. But we will become the most important supplier of electric buses and electric cars in the world with different things,” General said the US governor Joe Biden. Mr. Biden’s factory visit is done online, but experts consider it a very serious move and is part of the Government’s plan to promote the production of public transport powered by green energy. America. According to Hot Cars page, the US President’s declaration of “join the game” means that America must surpass China, which currently dominates the electric bus market. According to Biden’s roadmap, all US-made buses will be “completely green” by 2030. Proterra also estimates that half of the buses will be electrified by 2025. Students in the US mainly use the bus to get to school. (Photo: Hot Cars) Spend $ 20 billion to exchange electric buses for schools The aforementioned American bus electrification roadmap is not without foundation. Earlier, in early April, Mr. Biden announced the Huge Infrastructure Bill with a financial plan worth more than $ 2 trillion. This budget proposal includes items with many different packages. Worth noting is the $ 174 billion electric vehicle development package. In which the Government allocated 20 billion dollars to convert at least 20% of school buses in the United States to electric power. The rest of the buses will have to be changed by the schools through tightened policies. At least $ 20 billion will be spent by the US on converting to electric buses by 2030. (Image: Hot Cars) Additionally, an additional $ 25 billion will be spent converting public transport from internal combustion engines to electric. At the same time the US will spend up to 100 billion dollars on the policy to reduce prices to pull customers to buy more electric cars. With strong determination from the electrification of public transport, Mr. Biden has demonstrated a commitment to cutting greenhouse gas emissions. This also brings health benefits for people, especially students who regularly use buses to go to school. And most of all, Mr. Biden wants to reaffirm America’s position in the production of electric cars, including electric buses. Outstanding and behind China is difficult to accept.

Solar power is being encouraged to use, contributing to creating more clean energy sources, towards the goal of green and sustainable electricity development. Immediately after the Politburo issued Resolution 55-NQ / TW, on February 11, 2020 on the national energy development strategic orientation, the provincial People’s Committee directed the Department of Industry and Trade to coordinate with related agencies and units. research, advise and propose rooftop power development. Department of Industry and Trade proposed the Ministry of Industry and Trade to supplement the planning for 2 solar power plants in Viet Yen and Yen The; solar power projects in industrial zones and clusters with a total capacity of 2,320 MVA. Households in Luc Ngan district install solar power system on the roof. Photo provided by CTV. Mr. Nguyen Duc Hoan, Deputy Director of the Department of Industry and Trade, informed that although power companies stopped connecting and purchased solar power in the case of installation after December 31, 2020, it is only temporary. In general, the State has a mechanism to develop solar power with many attractive policies such as: Buying solar power at high prices, purchasing time lasts 20 years, commercial banks facilitate maximum loans from 70 -80% value of solar power projects in a period of 5-8 years. With the above advantages, many individuals, businesses (DN) and units have been encouraged to take advantage of this energy source. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system with a total installed capacity of 15,936.46 kWp. In which, 10 are enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units. It is known that since 2017, the province has implemented rooftop solar power development programs in a number of different forms, but mainly supported the installation of pilot models, demonstrations for the purpose of evaluation and replication. power saving; At the same time, it will support 10 state agencies to participate in the use of solar power in the near future. At this time, the Department is assigning the Center for Industrial Promotion and Trade Promotion to assist the People’s Committee of Luc Ngan district to install solar bulbs in the district People’s Committee square. The results and orientations of the province show that the development of solar power in the locality is increasing in both quantity and scale, especially in enterprises. This policy, in the immediate future, has brought about a clear effect, contributing to reducing the pressure, saving costs of developing transmission lines and using clean energy sources. Solve the expired solar battery problem The electricity obtained from the sun is clean energy, but when the solar panels expire, they become garbage, which is very dangerous. According to specialized agencies, the average service life of solar panels ranges from 10 to 20 years, depending on the location and the environment where it is installed. However, the handling of expired panels so far has not had a specific direction. A representative of the leadership of the Department of Industry and Trade – a permanent unit to advise on this content, said that in a written consultation with the Provincial People’s Committee on the development of rooftop power projects, the unit has not yet proposed specific measures for Dispose of the panels when the battery expires. By the end of December 31, 2020, the whole province had 607 customers installing rooftop solar power system, total installed capacity was 15,936.46 kWp. In which, 10 enterprises with a total installed capacity of more than 100 kWp or more, the rest are households and non-business units “. Mr. Nguyen Duc Hoan, Deputy Director of Department of Industry and Trade Discussing this issue with Mr. Nguyen Ba Trinh, an expert from the Department of Environmental Protection (Department of Natural Resources and Environment), it is known that the solar cell when its expiry date is hazardous waste. The disposal of this waste is very difficult, if not handled properly but burying in the wrong regulations, it will pollute the soil and water environment due to generation of heavy metals or toxic emissions. In the event of a fire the battery is capable of harming human health. There is only one unit in the province, Hoa Binh Industrial Waste Treatment and Recycling Joint Stock Company (Yen Dung) that is eligible to handle this type of waste, but the scale of treatment of the enterprise is small. Mr. Trinh also added that, according to Article 68 of the Law on Environmental Protection, the environmental protection responsibilities of owners of production, business and service establishments must “collect, classify, store, treat and dispose of. disposal of solid waste in accordance with the law ”, that is, the investor is responsible for handling the battery when it expires. Therefore, it may be worrisome that, after the expiration of its use term, households dispose of solar panels with domestic waste, do not hire the unit to collect, transport and dispose of it. Unattended authorities. Or the owner of the panel is not able to handle or dispose of the panel into the environment. Thus, solar power development associated with environmental sustainability has not been paid attention. New authorities focus on planning and encouraging expansion to reduce pressure on the national grid without giving specific solutions to handle solar cells when they expire. Some comments said that the functional agencies, especially the Department of Industry and Trade, the standing unit to advise on this content, should soon offer solutions to handle solar batteries after the expiration of use.

The price is easy to access, the maintenance cost is only 1/3 of a gasoline car Launched on March 24, VinFast VF e34 has an official selling price of VND 690 million, but for customers who ordered before June 30, 2021, the Vietnamese car company offers a special preferential price of only VND 590 million. Includes one-year free battery subscription. This is considered an accessible price for first-time car buyers, young families in big cities in Vietnam. Mr. Tuan Phong (30 years old) ordered VinFast VF e34 just one day after the car was introduced. He said, with outstanding technology such as electric motors, smart features and attractive pre-set price of only 590 million VND and extremely “open” pre-order policy, VF e34 persuaded him to “down money”. without any hesitation. “The battery rental policy that makes the car price more accessible is the first reasonable one. The second is an immediate incentive of 100 million dong for early booking, and the third one is a deposit of only 10 million dong and can be freely refunded / canceled / transferred without penalty, so I have no reason. to hesitate “, Mr. Phong said. According to Mr. Phong, young people often like “delicious-nutritious-cheap” cars because their financial resources are not abundant. With the same amount of VND 590 million, in addition to the VF e34, customers cannot even buy a standard B-class SUV, only a few high-end versions of B-class sedans. Meanwhile, VF e34 Being a model in the higher-end C-segment is clearly a bargain. For young people who buy a car for the first time, owning a car is still vague when it comes to solving some concerns such as the cost of buying a car, maintenance, repair, fuel and parking. Mr. Tuan Phong admitted this, thinking that he was no exception, so he decided to buy an electric car. According to him, VinFast VF e34 not only has the most competitive price in the market, but also has a much more optimal cost-effectiveness than traditional cars. “The cost of electric fuel is cheaper than gasoline, of course. Worth mentioning here is that the maintenance cost of VinFast VF e34 is only 25% -30% of gasoline cars due to its simpler structure, ”said Phong. According to calculations, the total maintenance cost for electric cars after the first 40,000 km is only about 4.4 million VND, and only costs about 12.7 million VND for 120,000 km. Not only that, with VF e34, early customers who order early are also free 17.4 million dong of battery subscription fee in the first year. Overflowing with technology Attractive price does not mean VinFast VF e34 has reduced features, but instead, the car is fully equipped with “toys” and is connected to a smart management application. Through the application, users can update vehicle software, perform many tasks such as checking battery status, travel schedule, maintenance schedule, call for rescue, warning of theft risk, vehicle positioning, error diagnosis … Young customers will also be pleased with the cabin compartment equipped with a 10-inch touch screen, Apple CarPlay and Android Auto connectivity, 6 audio speakers and 2 driver-row USB ports to connect or charge electrical devices. death. The air-conditioning system integrates the air quality control function with the fine dust filter HEPA PM2.5 which is also an advantage for the current air pollution. In addition, the voice control feature to support Vietnamese for multi-regional adaptation is also expected. List of long-term safety technologies, including ABS anti-lock braking, BA emergency brake assist, EBD electronic brake force distribution, ESC electronic balance, HSA horizontal start assist, 360 surveillance camera , lane departure warning, blind spot warning, traffic flow warning until door opening, vehicle warning when reversing, front and rear sensor, tire pressure monitoring, automatic throttle, 6 airbags … Help VinFast VF e34 achieve the highest safety standards. Environmental friendliness Growing up with the Internet, Generation Y and Z (Gen Y – Gen Z) are well aware of the urgency of protecting the environment. Many young people are gradually changing to choose means of using electric energy to limit the impact on the living environment. In the opinion that electric cars are not actually too good for the environment compared to traditional cars, due to the generation of electricity and batteries emitting a lot of CO2, the leading renewable energy company in the UK EDF Energy protested. Accordingly, even with more emissions in the current production process, electric cars are still a “greener” option than traditional cars when taking into account the vehicle lifecycle. That is not to mention that it will be easier and more efficient to treat the waste from the centralized battery production / recycling process in a closed process than to worry about a series of internal combustion engine vehicles discharging every day. . Technology to produce electricity and batteries is also developing and changing day by day, so emissions from manufacturing will be improved positively in the near future. According to EDF Energy, the biggest benefit of electric cars is improved air quality in large cities. Without exhaust pipes, electric cars have absolutely no NOx, HC, CO, CO2 emissions – a combination of exhaust gases that seriously affects human health and living environment. Simply put, electric cars are the foundation for cleaner and cleaner cities and roads. Another fairly common myth is that lithium-ion batteries are as toxic as lead batteries. In fact, lithium-ion batteries are safer, causing less harm to the environment or human health. At the same time, lithium-ion batteries are also of high economic value, so they will be collected, recycled and reused instead of being disposed of as lead batteries, so the risk of environmental pollution is also minimized. In particular, the solution to renting batteries instead of “selling off” cars with batteries to customers will help manufacturers like VinFast better manage the amount of batteries circulating in the market, ensuring that they will not be disposed of indiscriminately, causing harmful to the environment.
