The authors of Ho Chi Minh City University of Technology have applied blockchain technology to build a system for issuing and managing diplomas and certificates. To issue a certificate, the training institution registers an account and logs in to the system to create embryos. After filling in the student’s information, the course, etc., the training institution can print it to issue a certificate or issue a digital certificate. Each certificate is issued with a QR code, which can be looked up and verified on the student’s information and the certificate on the mobile application. The system helps to reduce time and costs for training institutions and quickly detect cases of tampering. The glue that helps regenerate nerve cells Researchers at the University of Georgia (USA) have studied a special glue in the form of hydrogel to aid in the recovery of brain cells. The researchers implanted the hydrogel into mice with traumatic brain injury. After 20 weeks, the mouse’s cell repair process was enhanced, motor function improved. The results showed that this glue not only protects tissues from damage, but also regenerates functional neurons at the affected site. The results of the study hold promise for the medical profession to prevent cognitive decline or tissue loss in patients with traumatic brain injury. New battery development Russian scientists have developed a new type of battery that can be charged about 10 times faster than commonly used lithium-ion batteries. Tests show that the new battery can work well in emergency charging situations and in low-temperature environments. The new battery is also safer for the environment.

Wiibike electric bicycles can quickly turn an ordinary bicycle into an electric bike by installing a kit made by the company itself. In the recent broadcast of “Silver billion deal”, the Wiibike electric bicycle project brought by CEO Nguyen Thi Thu Hang has received the investment of Shark Phu with 1.5 billion VND for 10% of the stock. part. And committed if the payback this year will increase the investment by 10 times. Wiibike is a science and technology startup in the green transport sector with the main product of complete electric bicycle, using lithium batteries. Notably, Wiibike’s chassis is made from a variety of materials, including one that uses bamboo, an environmentally friendly renewable material. In addition, Wiibike also offers a Wiibike kit to turn a regular bike into an electric power bike within 15 minutes. According to Mr. Lai Thai Phong – product development specialist of Wiibike, these are Make in Vietnam kits manufactured by the company. This kit comes with a sizing mechanism that can be mounted on any bike, including models with different wheel sizes. “The most important thing about the kit is how the battery is in it. To achieve high performance, the kit must use high capacity cells and good connectivity. This idea is researched and learned from technologies available in the world. ”, Mr. Phong shared. However, this enterprise is only in the consulting process to register for invention copyrights. The Wiibike electric power bicycle project received an investment of 1.5 billion VND for a 10% stake from Shark Phu According to Ms. Nguyen Thi Thu Hang – co-founder and operator of Wiibike, this start-up has a trial product since 2017. Currently, Wiibike is at 51% gross profit with revenue of 2.3 billion VND in 9 months, starting from July last year. “Although not yet implemented any traditional promotional campaigns, the project has attracted 300 customers to buy this car”, the project’s CEO shared. However, according to Shark Hung, this is not a new business model, it is difficult to approve that this is an invention that only stops at industrial designs or useful solutions. Vehicle design is not beautiful, does not show style, the numbers are not convincing. Therefore, the “real estate shark” has decided to ignore this deal. However, CEO Nguyen Thi Thu Hang maintains her stance when asserting that what she does will contribute to the value and make a great impact on the lifestyle and living environment of the Vietnamese people. Whether or not the capital is successfully raised, Thu Hang affirms that she will continue to fulfill this dream. “Wiibike’s orientation is not only at the product, but also to offer green transport solutions to really contribute to the transport system in Vietnam”, said founder of Wiibike. Finally, this start-up successfully raised capital from Shark Phu with an investment of 1.5 billion VND for a 10% stake.

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.

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.

The number of car charging stations is increasing globally and also in Vietnam.

The energy provided for electric vehicles is increasingly clean

The REN21 Global Renewable Energy (GSR) Report of 2020 (Global Multilateral Renewable Energy Policy Network) shows that, over the past 5 years, the renewable energy sector has reached its speed. 3 times higher than electricity produced from nuclear and fossil fuels.

“When the grid becomes ‘greener’, using electric vehicles will be more perfect ”, Gordon Bauer – electric vehicle researcher at the International Council for Clean Transport in San Francisco (USA) said. According to expert Gordon Bauer, the current innovative grid model will help improve the environmental efficiency of electric vehicles around the world.

The evidence is a study by scientists at the Lawrence Berkeley National Laboratory in California (USA) that if all personal vehicles in the US are powered by electricity, each year, the country will lose 46%. greenhouse gas (0.5 gigatons CO2 equivalent) compared to conventional fossil fuel cars.

This is what environmental activists expect. Anne Laurent, president of the All-European Environmental Union, admits the members “have no doubts” about the positive impact this vehicle can have on the planet.

“We do not expect a perfect solution. Therefore, we are delighted that electric vehicles deliver positive environmental indicators“Ms. Laurent said in a report released at the end of 2020.

In Vietnam, green vehicles are also developing with the launch of private cars and VinFast electric buses. And look at “National energy development strategy to 2030, vision to 2045” – with the goal that the renewable energy in the total primary energy supply will reach 15 – 20% by 2030 and increase to 25-30% by 2045 we have the right to hope for a “green future, clean air” when clean cars are powered by clean electricity.

Electric vehicle batteries are too expensive to be … garbage

In addition to generating electricity, environmental activists have been concerned about the fate of electric vehicle battery blocks after they have run out of “trumps”. Elon Musk was the “victim” of this wave of protest. But in fact, electric car batteries can not be thrown away because … too expensive, even after the expiry date.

The reason is that the prices of cobalt, lithium, nickel and the metals used in lithium-ion batteries have skyrocketed as the electric car race intensifies between manufacturers across Asia to Europe and the US. Therefore, all electric car manufacturers are researching and announcing solutions to handle expired batteries with battery recycling technology.

“To meet electric vehicle battery demand in the next 10 years, the industry will need 1.5 million tons of lithium, 1.5 million tons of graphite, 1 million tons of nickel and 500,000 tons of manganese. Today, the world produces less than a third of that material ”Sam Jaffe, CEO of Cairn ERA, an energy consulting firm in the US, told CNBC.

Some studies show that recycling can recover between 95 and 98 percent of the nickel, cobalt, copper, aluminum, and more than 80 percent of the battery’s lithium. Ms. Celina Mikolajczak, Vice President of Battery Technology and Technology at Panasonic Energy North America, said that the battery recycling industry will be a billion-dollar land with the development of electric vehicles.

“There are so many benefits to recycling and it would be really stupid if we didn’t take advantage of the old battery cells’ ability to make the next generation.”Ms. Celina Mikolajczak confirmed.

This excellent solution not only eliminates the worry of running out of production materials, but also removes electric vehicle batteries from the burden of the environment.

There are more than 50 companies around the world engaged in the recycling of lithium-ion batteries of varying sizes, most of them concentrated in China (more than 20 companies), followed by Korea (6 companies), followed by the EU, Japan, Canada and the US. Even global tech giant Amazon hasn’t overlooked this potential by investing $ 2 billion in Redwood Materials, a battery recycling startup founded by former Tesla chief JB Straubel. Redwood Materials is also responsible for recycling electric vehicle batteries for Tesla.

In addition to recycling batteries for reuse for electric vehicles themselves, a series of projects to utilize old batteries have been implemented recently by car manufacturers. Toyota has a project to connect old electric vehicle batteries with solar panels to power 7-Eleven stores in Japan; Nissan is using old batteries to power the small robots; Renault is working with its partners to introduce static energy storage systems made of old electric vehicle batteries … Other car manufacturers such as Audi, BMW, Lucid Motors or Proterra … are also incorporating reusable principles into their designs. the battery.

“We believe that the ‘second life’ battery will become an independent business and cannot be disposed of as trash.”, Weiland Bruch, BMW spokesman forecasts.

When the final concern was that electric vehicle batteries turned into environmental waste were completely eliminated – it’s easy to understand why green cars are supported by environmental activists around the world. And that will also be the green future that we need to move towards to escape the country’s “scandal” of the “two-wheeled gas factories” that international indicators set for Vietnam.
