When a charge state of an auxiliary battery transitions to a first charge state, a charge/discharge controller executes a first process in which a first voltage is applied to an in-vehicle power supply unit to charge the in-vehicle power supply unit with a constant voltage. When the charge state of the auxiliary battery transitions to a second charge state, the charge/discharge controller executes a second process in which a second voltage is applied to the in-vehicle power supply unit, charging of the auxiliary battery is stopped, and the auxiliary battery is caused to discharge electricity to an electrical component load or the like. The charge/discharge controller repeats the first process and the second process until a charge state of a lead storage battery transitions to a third charge state.
