In recent years, a considerable number of mandatory policies and regulations on the safety of new energy vehicles have been introduced, which has resulted in an increase in the technical requirements for the safety of new energy vehicle products and a slight improvement in the safety situation.
New energy vehicle fires were developing rapidly. Once a fire occurs in the lithium-ion battery in the vehicle, the high-temperature smoke and CO, etc. seriously endangered the safety of people inside the vehicle and the tunnel. It would reach a very dangerous situation in a short time.
As one of the core technologies of NEVs, power battery accounts for over 30% of the cost of NEVs, directly determines the development level and direction of NEVs. In 2020, the installed capacity of NEV batteries in China reached 63.3 GWh, and the market size reached 61.184 billion RMB, gaining support from many governments.
Due to the high-temperature smoke generated by battery thermal runaway, the plume temperature of new energy vehicle fires was significantly higher than that of fuel vehicles, and the maximum temperature of the ceiling in new energy vehicle fires reached about 220 °C. Fig. 9. Temperature slices with HRR was 3 MW in the tunnel (Z=7.8 m).
In 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.
It is worth pointing out that fault diagnosis and warning are crucial to the operational safety of the power batteries as well. In terms of safe running of new energy vehicles, attention should also be paid to advanced alert research based on running data for failure scenarios such as thermal runaway, power interruption and sudden speed-up. 5.
