In case of collision, which is more likely to explode, a pure electric vehicle or a fuel vehicle? To answer this question, we must first know the difference between the two modes. I believe that everyone is familiar with traditional fuel vehicles, while pure electric vehicles are new models that have been continuously developed in recent years. From the structural point of view, pure electric vehicles are equipped with battery packs, which are matched with motor-driven vehicles, and there are no fuel engines, gearboxes, fuel tanks and other accessories. At present, the batteries carried by pure electric vehicles mainly use ternary lithium batteries, and some models use lithium iron phosphate batteries, both of which belong to liquid lithium ion batteries.

As a liquid lithium-ion battery, if the battery is deformed during collision, it will easily lead to short circuit and the temperature will rise rapidly. In order to improve the cruising range of pure electric vehicles, the battery energy density is relatively high, so the speed of spontaneous combustion will be faster. In addition, the battery is an energy storage device with high internal voltage, which makes the pure electric vehicle easy to explode.

Traditional fuel vehicles are equipped with fuel engines, gearboxes and fuel tanks that match the driving vehicles. Although there is a fuel tank, it may explode, but the fire of traditional fuel vehicles is generally caused by circuit failure or fuel leakage, and the proportion of circuit failure is higher. In addition, traditional fuel vehicles have fewer lines than pure electric vehicles, so the possibility of spontaneous combustion and explosion is reduced.

Therefore, it is not difficult to see that pure electric vehicles are more prone to spontaneous combustion and explosion than traditional fuel vehicles, so many car companies have begun to improve the stability of power batteries, such as developing solid-state batteries and studying BMS battery management systems. So as to reduce the spontaneous combustion of pure electric vehicles in the use process to a certain extent, and improve the use safety of pure electric vehicles.
