Research and analysis of electric vehicle fire accidents and review of lithium-ion battery thermal runaway mechanism

Abstract

: The rapid development of electric vehicles is accompanied by numerous security issue, which has caused people great concern. This paper counts the electric vehicle fire accidents in the past six years, and from three different perspectives: the time of the accident, the type of vehicle involved and the type of vehicle power to discuss these accidents. Then analyzed the various causes of electric vehicle fire accidents, such as spontaneous combustion, crash fire, etc. Explaining the three major causes of thermal runaway and the mechanism of thermal runaway in batteries. Proposing some measures and suggestions to solve the thermal runaway of electric vehicles. Through the conclusion and analysis of these accidents, this paper hopes that the new energy electric vehicles can be developed more safely and better.
