Abstract
An electrified vehicle includes a system main relay attached to an electric power line for motive power and a charging relay attached to a charging electric power line through which a portion of the electric power line for motive power positioned between the system main relay and a drive circuit and a vehicle-side connection portion connected to a station-side connection portion of a direct current charging station are connected to each other. When the vehicle-side connection portion and the station-side connection portion are disconnected from each other while an electric storage device is being charged with electric power from the direct current charging station, diagnosis about double-pole welding abnormality of the charging relay is performed after the charging relay is turned off with the system main relay being in a turned-on state and the system main relay is turned off after the diagnosis.
