Abstract
An ECU operates a charging unit such that a power storage device is charged by an electric power from a power supply. When a vehicle moves while charging the unit charges the power storage device, the ECU stops charging the unit to discontinue the charging of the power storage device. The ECU diagnoses a state of the charging unit after the charging of the power storage device is stopped. The ECU determines whether the charging of the power storage device is able to be resumed based on the diagnostic result. When determining that the charging of the power storage device is able to be resumed, the ECU resumes the charging of the power storage device by resuming the operation of the charging unit.
