摘　　要：根据电动车静止非充电状态下失火自燃的可能性进行研究,分析了电动车失火自燃的必要条件,得出了电动车电池连接线短路是发生电动车火灾的主要原因。根据事故树分析法构建出电动车火灾的事故树模型,计算出结构重要度系数和临界重要度系数,并得出电动车静置非充电状态下存在失火自燃的概率。Based on the study of the possibility of electric vehicle fire and spontaneous combustion in a stationary non charging state,the necessary conditions for electric vehicle fire and spontaneous combustion were analyzed,and it was concluded that the short circuit of the electric vehicle battery connection line is the main cause of electric vehicle fire.Based on the fault tree analysis method,a fault tree model for electric vehicle fires is constructed,and the structural importance coefficient and critical importance coefficient are calculated.The probability of fire and spontaneous combustion of electric vehicles in a non charging state is also determined.
