INTEGRATED CHARGER AND CHARGING METHOD FOR ELECTRIC VEHICLES

Abstract: an integrated charger for electric vehicles employs a multi-phase auxiliary motor on the vehicle to charge the traction battery. the stator of the electric motor includes first windings and second windings that are phase-staggered. one of the sets of windings is put into connection with an external ac power source via a switching unit, which also isolates the vehicle's traction battery from the external source. the ac current excites an alternating current in the second windings, which is rectified and used for charging the traction battery.
