Abstract

Abstract: In view of the burning and explosion accidents of new energy vehicles,the paper was aimed at studying the prevention measures by using the FFMEA method.Based on the statistical accidents data of new energy vehicles in China,the causes of the accidents were analyzed.Then the vehicles are divided into five subsystems through the FFMEA assessment of the various subsystems.It is found that the power subsystem is the largest risk source followed by the infrastructure subsystem,that the battery pack short circuit,battery thermal runaway,and charging pile without overload are also the main failure modes with a high risk,and that prevention and control measures such as optimizing the battery structure,installing collision automatically cut off power sensors and constructing overcharge detection devices will be effective in decreasing the risk.

Key words: new energy vehicle, burning and explosion, risk analysis of accident, fuzzy failure mode and effect analysis (FFMEA), fuzzy risk priority number (FRPN)
