AI Customer ServiceIn this study, we counted the known combustion accidents of new energy vehicles, analyzed the cause of a NEV combustion accident, and proposed a method to warn abnormal vehicles. The main conclusions are as follows: Thermal runaway of the power battery was usually the root cause of combustion accident.
The results from their study revealed that the lack of a reactive environment outside the battery could effectively inhibit the combustion process of TR. The absence of combustion could avoid damage to the battery shell and reduce the possibility of uncontrolled TR propagation.
Every year, many waste batteries are thrown away without treatment, which is damaging to the environment. The commonly used new energy vehicle batteries are lithium cobalt acid battery, lithium iron phosphate (LIP) battery, NiMH battery, and ternary lithium battery.
The statistics of combustion accidents of new energy vehicles in China from 2017 to 2021 are shown in Fig. 1. As customer acquisition continues to increase, new energy vehicle combustion accidents are also on the rise, with electric vehicles accounting for more than 90 % of accident vehicles.
Compared to the electrical energy stored in the battery, the thermochemical energy released from the battery fire, including both the thermal runaway heat inside the battery (i.e., the internal heat) and flame sustained by the flammable gases injected from the battery (i.e., the flame heat), is much higher [18,39,40].
Once the onboard battery involved in fire, there is a greater difficulty in suppressing EV fires, because the burning battery pack inside is inaccessible to externally applied suppressant and can re-ignite without sufficient cooling.
