Abstract

Abstract:

At present, China is the largest market of new energy vehicle in the world. In recent years, the vehicle fire accidents which are frequently reported have become the "roadblocks" for the large-scale popularization and application of new energy vehicles. Most of the accidents are closely related to the power battery. It is of great significance to carry out in-depth and systematic analysis on the safety failure of power battery for locating the cause of the accident and further reducing the fire accidents of new energy vehicles. Based on the fire accident analysis of new energy vehicles, this paper systematically analyzes the potential causes of failure from materials, cell design, production and manufacturing, battery pack system integration and management of power battery, so as to guide the improvement of safety quality of battery products.

Key words: new energy vehicle, fire accident, power battery, spontaneous combustion incentives, full life cycle
