In recent years, vehicle safety has become a key concern of consumers, especially new energy products. Due to the frequent occurrence of accidents such as spontaneous combustion and broken axles of electric vehicles, consumers are more suspicious of the safety of new energy products.
Just a few days ago, BYD Chairman Wang Chuanfu said at the new car launch conference: “Safety is the greatest luxury of electric vehicles.” He also announced that BYD’s all-electric models have begun to switch the blade batteries and start acupuncture testing. As a corporate standard. From this point, we can see that BYD’s determination to build safety products and its confidence in blade batteries.
In addition to the active and passive safety of the vehicle itself, the health and safety indicators of the vehicle are also important, because there may also be colorless, odorless and invisible “killers” in the vehicle. The indicators of volatile organic compounds (VOC), odor intensity (VOI), and electromagnetic radiation (EMR) of vehicles should also arouse our attention.
In fact, BYD paid attention to these early and has already taken action. It is worth mentioning that BYD’s flagship sedan Han won the five-star evaluation of the “China Automobile Health Index” and the honor of the recommended model in 2020. BYDhan’s three indicators of VOC, VOI, and EMR have reached the industry’s excellent level. It is very difficult to control each indicator. How does BYD do it?
Everyone knows that carcinogens such as formaldehyde and benzene are called “invisible killers.” Due to the use of PVC materials and asphalt, these volatile organic compounds will exist in the car. The concentration of these substances exceeds the standard and poses a threat to people’s health.
BYD has been doing research on volatile organic compounds (VOC) since 2009 and established a fully equipped VOC vehicle test room in 2012. Han adopted a new “baby-grade” coating and cleaning process, replacing all PVC materials with PU materials, and using water-based LASD spray-type damping materials to replace traditional asphalt damping materials for body sound insulation materials to reduce air pollution in the car.
At the same time, in the vehicle VOC laboratory and auto parts VOC laboratory, BYD increases the ambient temperature, increases the volatilization rate of organic substances, and detects the concentration of harmful substances to ensure that various parts and vehicles can meet the standards.
Of course, most products on the market can guarantee that volatile organic compounds are within the standard, but the smell in the car is unacceptable. Although smelling does not mean it is harmful, too much smell makes people in the car feel uncomfortable. Therefore, BYD has set up a special odor identification team to strictly control the comfort of the odor in the car through sniffing. There is no doubt that Han has set the interior odour index in the early stage of development.
In fact, BYD’s odor identification team has gone through a complicated training process, and the employment standards are very strict. Team members must have good living habits, do not smoke, do not drink, have a good work and rest, etc., and are sensitive to smells. Through six months to one year of training on odor sensitivity and memory, team members have exercised a “golden nose” and rated the tested components.
In addition to VOC and VOI, BYD is also very concerned about electromagnetic radiation (EMR) from vehicles. Have you heard of these rumors, such as “5G base stations have high radiation and are harmful to health”, “riding a high-speed train is equivalent to taking X-rays”, “flighting on a plane is equivalent to having 10 chest X-rays”, etc. These rumors have no scientific basis. As a new energy product, electric vehicles will also produce electromagnetic radiation. Although there is no evidence that the electromagnetic radiation of automobiles can cause harm to the human body, BYD will still reduce the level of electromagnetic radiation in the car, so that consumers can rest assured.
Through a large number of scientific experiments in leading laboratories, BYD has controlled the electromagnetic radiation level in the car to be lower than that of air conditioners and LED lights. Han’s vehicle system has been optimized and designed to ensure that the electromagnetic radiation of the vehicle is at a low level under high-speed, rapid acceleration and deceleration conditions. Moreover, in the field of automotive electromagnetic compatibility, BYD has invested a lot of energy and money, and conducted a large number of exploratory tests to ensure that its products can reach higher standards.
Consumers are paying more and more attention to the health and safety of vehicles, as Wang Chuanfu said: “Safety is the greatest luxury of electric vehicles.” For car companies, what they have to do now is to do more research, because the more research, the greater the gain. If you want to stay ahead, you have to explore a lot of things on your own.
