A control method is performed to control first and second storage devices that are connected in parallel to an electric generator in which the second storage device has a lower internal resistance than that of the first storage device. In a case where a driver has requested automated driving during charging of the first storage device (e.g., a lead-acid battery) in a state in which a generator and the second storage device (e.g., a lithium-ion battery) are disconnected, the generator and the second storage device are electrically connected even when a charge ratio of the lead-acid battery is less than a prescribed percentage. In a case where the driver has not requested the automated driving, the generator and the second storage device are electrically connected after the charge ratio of the first storage device has reached the prescribed percentage.
