高速高严重性碰撞条件下纯电动汽车火灾危险性分析及应急救援研究

Study on Fire Hazard Analysis and Emergency Rescue of Battery Electric Vehicles under High-speed and High-severity Collision Conditions

结合国内外对锂离子电动汽车火灾危险性与应急救援的研究情况,重点分析了高速高严重性碰撞后锂离子电动汽车火灾危险性。针对热失控、触电风险和滞留能量三个突出风险点,对电动汽车火灾应急救援处置要点进行了讨论,为此类事故救援研究提供参考。

Based on the research on the fire hazard and emergency rescue of lithium-ion electric vehicles at home and abroad,the fire hazard of lithium-ion electric vehicles after high-speed and high-severity collision is mainly analyzed.Aiming at the three prominent risk points of electric vehicle fire:thermal runaway,electric shock risk and stranded energy,the key points related to the emergency rescue of electric vehicle fires were discussed,providing a reference for the rescue research of such accidents.
