Abstract :
This system was developed to monitor on-line insulation resistance of electric vehicle via insulation voltage measurement. The influence of detection error and battery voltage fluctuation on the result precision was analyzed in detail, and measures were put forward to get better accuracy. System was designed and put into practical use. And some experimental data were acquired and presented to validate its applicability for electric vehicles.
