Is the frequent fire of new energy vehicles related to the battery?

According to investigations, these types of vehicles that caught fire included passenger cars and passenger cars. From the perspective of the supporting batteries, there were ternary batteries and lithium iron phosphate batteries. Maybe everyone does not know much about batteries, but the general consensus reached in the battery industry is that ternary batteries are relatively safe for lithium iron phosphate batteries. However, in recent years, because of the natural advantages of high energy density, ternary batteries have gradually become the mainstream power lithium batteries used in new energy vehicles. Why do they still use them if they know that they are low in safety? This is related to the mileage of the battery. The popular point is that the ternary battery has a stronger endurance. It is necessary to understand that most of the customers who buy a car care about the endurance. Under the pressure of competition between various brands, the endurance is A very big selling point, but also related to sales issues, so if you want to travel farther with a single charge, you must increase the energy density per unit weight of the battery. In fact, the stability of the battery itself has been done well by major battery manufacturers, but the reason for frequent safety problems is the complex environment in actual use. According to public statistics, May and June are the peak periods for electric vehicle fires. It is not difficult to find that with the advent of summer, weather such as high temperature and heavy rain will affect the safety of electric vehicles. It can also be seen from another aspect. , It’s not doing a good job in battery temperature control. In addition, because most of the batteries of new energy vehicles are located at the bottom, once heavy rain comes, the battery will leak, which will cause the battery to leak. Generally speaking, as a closed energy system, lithium-ion batteries are difficult to be compatible with high energy density and safety in principle. The higher the energy density of the battery, the higher the probability of a combustion explosion. With the development of new energy, the country also attaches great importance to safety issues. Many unqualified automobile companies have been punished and audits have become more and more stringent.
