Abstract
An electric vehicle incorporates a ground fault detecting system for preventing a ground fault detector from detecting a ground fault in error. First and second ground fault detectors are associated respectively with first and second ungrounded power supplies which generate respective different voltages. Since the first and second ground fault detectors are activated in different periods, the ground fault detecting system prevents a ground fault from being detected in error.
