摘要： A vehicle power supply control system includes a solar panel, a drive battery, an auxiliary battery, an auxiliary system that is powered by the solar panel and the auxiliary battery, an acquisition unit, and a controller. The acquisition unit is configured to acquire power generated by the solar panel and power consumption of the auxiliary system. The controller is configured to control power supply from the solar panel to the drive battery based on the power generated by the solar panel and the power consumption of the auxiliary system when the power supply from the solar panel to the drive battery is possible.

摘要： A solar charging system includes a solar panel, a power conversion unit configured to output electric power generated by the solar panel, a battery configured to be directly charged via the power conversion unit with electric power generated by the solar panel, and one or more processors. The one or more processors are configured to transmit, to the power conversion unit via a communication line, a signal that controls a charge enable or disable status of charging from the solar panel to the battery, and determine whether an abnormality in the communication line is present based on the electric power generated by the solar panel, and a voltage at a middle point between the solar panel and the battery.

摘要： A vehicle includes a solar panel and a vehicle control device. The vehicle control device is configured to control supply of electric power generated by the solar panel, configured to count the number of power supply operations in which the electric power is supplied from the solar panel to a target device that is a power supply destination, configured to determine whether the number of power supply operations satisfies a first condition, to configured execute power supply from the solar panel to the target device when determination is made that the number of power supply operations satisfies the first condition. The vehicle control device is configured not to execute the power supply from the solar panel to the target device when determination is made that the number of power supply operations does not satisfy the first condition.

摘要： The solar charging system according to the present embodiment includes a solar panel, a drive battery, an auxiliary system including one or more devices, and a controller that controls where to supply power generated by the solar panel. The controller determines whether the solar panel can generate power, and, upon determining that the solar panel can generate power, supplies the power from the solar panel to the auxiliary system to derive the power generated by the solar panel. Upon detecting a fact that the power generated by the solar panel is equal to or greater than a first power, the controller further supplies the power from the solar panel to the drive battery to charge the drive battery.
