Abstract
An electric vehicle incorporates a ground fault detecting system and has first and second ungrounded power supplies. The ground fault detecting system includes a first insulation resistance detector for detecting a first insulation resistance of the first ungrounded power supply with respect to a grounded region of the electric vehicle, and a second insulation resistance detector for detecting a second insulation resistance of the second ungrounded power supply with respect to the grounded region. The first insulation resistance detector and the second insulation resistance detector detect the first insulation resistance and the second insulation resistance at different times, respectively.
