<p>An electric system for an electric vehicle enabling a secondary battery to be charged easily without using a large capacity and bulky charging system. The system can maintain integrity of power on a distribution network during charging. When charging the secondary battery, a switch connecting an inverter to an AC motor is opened, and then, the AC voltage from an external distribution network is supplied to the AC side of the inverter. The inverter rectifies the AC voltage to a DC voltage under the control of a control circuit so that the secondary battery is charged by the DC voltage. In another example, the windings of the AC motor may be connected between the distribution network and the inverter by the switching operation of a three-pole contactor so that the windings function as AC reactors.</p> |
