Abstract: When a microcomputer does not charge an electric storage device, the microcomputer activates at an interval set based on a timer set value and determines whether an electric power voltage generated by a solar cell is equal to or higher than an electric power generation determination threshold. When the generated electric power voltage is lower than the electric power generation determination threshold, the microcomputer turns to a sleep state after increasing the timer set value by an addition set value while prohibiting charging the electric storage device. When the generated electric power voltage is equal to or higher than the electric power generation determination threshold and a generated electric power amount is equal to or larger than an electric power generation determination threshold, the microcomputer starts charging the electric storage device so the electric power device can be appropriately charged with an electric power generated by the solar cell.

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.

Abstract: 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.

Abstract: To increase electric power generation efficiency of a solar panel while effectively using heat accumulated in the solar panel, a panel-side pipe is installed on a rear surface of the solar panel. The panel-side pipe is connected to an engine coolant passage. When a power switch is in an OFF state, and an exchange condition for a coolant is satisfied, an engine ECU drives a water pump to circulate the coolant to the panel-side pipe. Consequently, the cool coolant accumulated in the engine coolant passage and the warmed coolant accumulated in the panel-side pipe are exchanged with each other. As a result, the solar panel is cooled, and the engine is warmed.
