基于新能源汽车“三电”系统功能安全技术的探讨

Discussion on Functional Safety Technology Based on New Energy Vehicle"Three Power"System

相较于传统燃油车,新能源汽车掌握着电池、电机和电控这“三电”部分的核心技术。然而近年来,随着一系列电动汽车自燃事件的发生,新能源汽车的“三电”系统功能安全问题日益受到关注。本文对ISO 26262标准下汽车电子电气系统的开发流程加以分析,并对新能源汽车“三电”系统的功能安全技术展开探讨。

Compared with traditional fuel-powered vehicles,new energy vehicles have the core technologies of the"three electrics"part of batteries,motors and electronic controls.However,in recent years,with the occurrence of a series of spontaneous combustion of electric vehicles,the functional safety of the"three power"system of new energy vehicles has attracted increasing attention.This paper analyzes the development process of automotive electronic and electrical systems under the ISO 26262 standard,and discusses the functional safety technology of the"three power"systems for new energy vehicles.
