<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 (1), a switch (60) connecting an inverter (4) to an AC motor (5) is opened, and then, the AC voltage from an external distribution network (500) is supplied to the AC side of the inverter (4). The inverter (4) rectifies the AC voltage to a DC voltage under the control of a control circuit (4A) so that the secondary battery (1) is charged by the DC voltage. In another example, the windings of the AC motor (5) may be connected between the distribution network (500) and the inverter (4) by the switching operation of a three-pole contactor so that the windings function as AC reactors. <IMAGE></p> |
