摘要/Abstract

摘要： 为研究新能源汽车燃爆问题,采用模糊故障模式与影响分析(FFMEA)法对新能源汽车燃爆事故风险和防控对策开展研究。根据我国新能源汽车燃爆事件的统计数据,分析其致因机制,并将新能源汽车划分为整车控制系统、驱动电机系统、辅助系统、电源系统和基础设施系统等5个子系统,对其开展FFMEA分析;最后基于分析结果提出针对性防控对策。结果表明:电源系统是最大的风险源,其次是基础设施系统,电池组短路、电芯热失控和充电桩无过载、短路保护等故障为风险较大的故障模式;提出优化电池结构、安装碰撞自动切断电力传感器、建设过充故障检测装置等防控对策。

关键词: 新能源汽车, 燃爆, 事故风险分析, 模糊故障模式与影响分析(FFMEA), 模糊风险优先数(FRPN)

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)
