| Abstract: | High voltage insulation performance of electric vehicles is directly related to the personal safety of driv-ers and passengers.Since the traditional passive insulation resistance detection method has poor anti-jamming perform-ance and can not be measured under specific conditions,it has its use limitation in some cases.Based on the depth analysis of passive insulation resistance detection method,a new insulation detection method is proposed.The new method,which is used to detect the insulation resistance by... |
