Abstract

See full text

A solar ECU included in a charging controller is configured to temporarily store electric power generated by an in-vehicle solar cell of an electric power supply unit in a low-voltage battery when a vehicle is traveling. Further, when the vehicle is traveling, a battery ECU included in the charging controller is configured to maintain a charging relay in an open state (disconnected state) so that the electric power temporarily stored in the low-voltage battery is not supplied to a main battery. On the other hand, when the vehicle is traveling, the solar ECU supplies the electric power temporarily stored in the low-voltage battery to a sub-battery.
