The present invention relates to an electric power conversion system for a vehicle, which comprises: an AC-DC conversion circuit which converts AC charging power into DC power; a motor whose one end includes a plurality of coils mutually connected at a neutral point; a first switching apparatus which selectively supplies or blocks the output of an AC-DC conversion circuit to or from the neutral point; an inverter which includes a plurality of switching devices which have a plurality of motor connection ends, which are respectively connected to the other end of the coil in the motor, and DC connection ends, which include a positive terminal and a negative terminal, and which form electric connection relation between the DC connection ends and the plurality of motor connection ends; a battery connected to the DC connection end of the inverter; and a controller which controls the operation of the AC-DC conversion circuit, the first switching apparatus, and the inverter based on whether the battery is charged or not. The present invention is able to make a lighter and smaller electric power conversion system.
