Safety analysis and forecast of new energy vehicle fire accident

Abstract

In recent years, due to the aggravation of air pollution and the exhaustion of coal and oil resources, new energy vehicles have achieved rapid development. However, new energy vehicles have many hidden dangers. Spontaneous combustion, explosion and other accidents often occur all over the world, which restrict the development of new energy vehicles. In this paper, the fault tree analysis method is used to qualitatively analyse the new energy vehicle, the accident diagram is obtained, the importance of each basic event is analysed, and the fuzzy decision method is used to predict the fire accident of new energy vehicle.
