1. A vehicle power supply control system comprising:
a solar panel;
a drive battery;
an auxiliary battery;
an auxiliary system configured to be powered by the solar panel and the auxiliary battery; and
an electronic control unit configured to
acquire an amount of power generated by the solar panel and an amount of power consumption of the auxiliary system, and
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 in a drive battery charge mode, wherein power supply from the solar panel to the drive battery is possible in the drive battery charge mode,
wherein the electronic control unit is configured to supply power from the solar panel to the drive battery in a case that the power generated by the solar panel becomes equal to or greater than a sum of a previous power consumption of the auxiliary system and a predetermined first power before a first time elapses after start of power supply control for the drive battery, the previous power consumption of the auxiliary system being power consumed by the auxiliary system in a last drive battery charge mode.
