An electric system of an electric vehicle, in which an AC voltage is applied from an external AC power source to the inverter (4) via windings (51, 52 and 53) of an AC motor during the charging operation of a secondary battery (1). The inverter has a regenerative function enabling reverse conversion, and the motor windings operate as reactors. A contactor (6) whose first terminals are connected to terminals of the windings and whose second terminals are shortcircuited is provided. The first terminals of the contactor are connected via connecting lines (66) to a charging connector (210a) which is to be connected to the external power source. A portion of the vehicle body (110) is connected to the charging connector via a ground line (67), and is grounded. The contactor is opened when the secondary battery is charged, and is closed when the electric vehicle is driven. <IMAGE> |
