Abstract:
In order to study the fire problem of new energy vehicle caused by the thermal runaway of power batteries,some fire incidents of new energy vehicle in 2023 and 2024 were statistically analyzed,and the failure modes of battery thermal runaway,caused by mechanical abuse,electrical abuse and thermal abuse,were specifically analyzed from the perspective of whole vehicle.The characteristic parameters of battery thermal runaway were reviewed,and a real vehicle case of fire caused by battery thermal runaway was analyzed based on the characteristic data and field investigation.Finally,the methods to improve the safety of power battery were described.The results show that the main reason for the fire of new energy vehicle caused by power battery failure is the thermal runaway of battery.The multi-parameter collaborative analysis of temperature and voltage can achieve the accurate judgment of battery thermal runaway,help locate the fault modules and monomers,and provide key investigation directions.The research results can provide reference for the operation safety of power battery for new energy vehicle.
