Further, when the vehicle (100) is traveling, a battery ECU (32) included in the charging controller (30) is configured to maintain a charging relay (27) in an open state (disconnected state) so that the electric power temporarily stored in the low-voltage battery (22) is not supplied to a main battery (18). On the other hand, when the vehicle (100) is traveling, the solar ECU (31) supplies the electric power temporarily stored in the low-voltage battery (22) to a sub-battery (19).",
