A wireless power transfer (WPT) method for an electric vehicle (EV) may include a vehicle controller or a vehicle assembly (VA) controller connected to the vehicle controller performing communications, for charging of a battery of the EV, with a ground assembly (GA) controller of a charger connected to a primary coil or a primary pad located outside the EV; and connecting the battery to a field winding of a driving motor of the EV before starting the WPT. The battery is charged by a power magnetically induced at the field winding from the primary coil.
