摘要
以两起由锂电池故障引发的火灾为例,对火灾事故调查进行剖析,并比对锂电池热失控的模拟实验,总结出动力锂电池发生火灾有其不同于常见火灾的起火特征。通过机理分析做出验证,认为动力锂电池火灾在起火初期的本质是气体火灾,具有爆炸起火的特征。研究成果可供火灾事故调查参考。
Two fires caused by lithium battery failures are taken as an example to analyze the fire accident investigation, and compared with the simulation experiment of lithium battery thermal runaway.It is concluded that the fire of the power lithium battery has different ignition characteristics than the common fire. It is verified by mechanism analysis that the essence of the power lithium battery fire in the initial stage of the fire is gas fire, which has the characteristics of explosion and fire. The study results can be used fire accident investigation.
