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.

Vehicle power supply control system to control power from a solar panel and an auxiliary battery, vehicle comprising the power supply control system, and method of controlling power supply from a solar panel and an auxiliary battery

A solar charging system mounted on a vehicle includes a power generation module using a solar panel, an auxiliary system including an auxiliary machine battery for storing electric power generated by the power generation module and an auxiliary machine load to which electric power is supplied from the auxiliary machine battery, a high-voltage battery used for driving the vehicle, and a control unit provided between the high-voltage battery and the auxiliary system and controlling power transfer between the high-voltage battery and the auxiliary system. In a case where power transfer from the high-voltage battery to the auxiliary system is requested, when the power generated by the power generation module is not supplied to the auxiliary system, the control unit supplies power of the high-voltage battery to the auxiliary system.

Solar charging system

The control device scans the output voltage of the first converter within a predetermined range to search for a maximum-efficiency voltage. At that time, the control device controls the output voltage of the first converter to the first voltage and acquires the output power of the first converter at that time as the first power, controls the output voltage of the first converter to the second voltage changed by the first change width from the first voltage and acquires the output power of the first converter at that time as the second power, and controls the output voltage of the first converter to the third voltage changed by the second change width from the second voltage in order, and sets the second change width to a value larger than the first change width when the second power is smaller than the first power.

Control device of solar power generation system

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.

Vehicle control device, vehicle control method, non-transitory storage medium, and vehicle

An in-vehicle solar charge control system includes a path switching unit provided in parallel with the first DC-to-DC converter on an electrical circuit that connects a solar DC-to-DC converter and a first battery and through which electricity having output power flows, and a switching unit controller which switches the path switching unit between a first state in which the output power is supplied to the first battery without being input to the first DC-to-DC converter, and a second state in which the output power is allowed to be input to the first DC-to-DC converter that is switched to the first operating state by a converter control unit.

In-vehicle solar charge control system, in-vehicle solar charge control method, and program

A vehicle control device configured to control supply of electric power generated by a solar panel mounted on a vehicle includes a supply destination setting unit configured to set, based on a condition of the vehicle, a target device that is a destination for the supply of the electric power generated by the solar panel, a target setting unit configured to set, depending on the target device set by the supply destination setting unit, target output electric power to be output from the solar panel to the target device, and a power controller configured to control the electric power to be supplied from the solar panel to the target device based on the target output electric power set by the target setting unit.

Vehicle control device, control method, non-transitory storage medium, and vehicle

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.
