Original Abstract Submitted

Electrified vehicle includes a first motor, a battery for supplying power to the first motor, a first inverter for converting DC power from the battery into AC power supplied to the first motor, a charging inlet for receiving charging power for charging the battery, a charging circuit for connecting the charging inlet to the first inverter via a neutral point of the first motor, and a control device for controlling the operation of the first inverter. The charging circuit includes a charging smoothing capacitor provided between the charging inlet and the first motor. After the charging of the battery by the charging device is completed, the control device causes the first inverter to perform the boosting operation to discharge the charge accumulated in the charging smoothing capacitor from the first inverter to the battery side.
