CHARGING CONTROL DEVICE USING IN-VEHICLE SOLAR CELL

摘要

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.

主权项

1. A charging control device configured to use an in-vehicle solar cell installed in a vehicle, which is to be applied to the vehicle,
the vehicle comprising:
a motor generator configured to generate a driving force and to generate regenerative electric power; a main battery electrically connected to the motor generator, the main battery being configured to supply electric power to the motor generator and to store the regenerative electric power; and a sub-battery configured to supply electric power to various accessory devices mounted on the vehicle, the vehicle being capable of traveling using at least the driving force generated by the motor generator, the charging control device comprising: an electric power supply unit comprising the in-vehicle solar cell, which is configured to supply electric power generated by the in-vehicle solar cell to at least one of the main battery and the sub-battery; and a charging control unit configured to control charging of at least one of the main battery and the sub-battery using the electric power generated by the in-vehicle solar cell and supplied from the electric power supply unit, the charging control unit being configured to, when the vehicle is traveling, prevent the electric power generated by the in-vehicle solar cell from being supplied from the electric power electric power unit to the main battery.
