Abstract
A motor-driven vehicle includes a system main relay that is attached to a running electric power line connecting a power storage device to a drive circuit, a capacitor that is attached to the running electric power line between the system main relay and the drive circuit, and a charging relay that is attached to a charging electric power line connecting a vehicle-side connector to the running electric power line between the system main relay and the drive circuit. When a stand-side connector is disconnected from the vehicle-side connector while the power storage device is being charged with electric power from a direct-current charging stand, the charging relay and the system main relay are turned off, a two-pole welding abnormality of the charging relay is diagnosed using a voltage of the capacitor, and then the capacitor is discharged.
