摘要
分析纯电动车高压部件与车身之间存在高电压的原因,阐述用万用表检测高压部件对车身的电压存在干扰的原因,指出通过双万用表法测量可消除这种干扰,并对这种现象进行实物模型验证。
This paper analyzes the reason of high voltage existed between the high voltage components and the vehicle body of a pure electric vehicle,expounds the principle of interference existed when the voltage is detected between the high voltage components and the vehicle body by using the multimeter,points out that the interference can be eliminated through the measurement by using dual multimeters,and verifies the phenomenon by the physical model.
