Abstract
A vehicle power supply control method includes switching, when a constant voltage is required of a power supply circuit in generating electric power by a power generator, the power supply circuit being connected to a primary storage battery and configured to be connected to a secondary storage battery that has a lower internal resistance than that of the primary storage battery, between connection of the secondary storage battery to the power supply circuit and disconnection of the secondary storage battery from the power supply circuit depending on the required constant voltage, current output to the power supply circuit by the power generator, and a state of charge of the secondary storage battery.
