Abstract
When the amount of charge of a temporary battery exceeds a predetermined amount of charge, a solar ECU31 constitutes a charge controller pumps up and boosts power stored in the battery collaborating with a solar charger of a power supply portion, and carries out pumping charge in a main electric storage. While the solar ECU31 carries out the pumping charge, the power supply portion solar charger supplies the generated power from an in-vehicle solar cell to solar ECU31 when the power generated by the in-vehicle solar cell is a predetermined power or less, and supplies the generated power from an in-vehicle solar cell to solar ECU31 and main battery when the power generated by the in-vehicle solar cell is larger than the predetermined power. Even where the pumping charge is being carried out, the power which the in-vehicle solar cell is continuously generating can be used without being discarded futilely.
