A power supply system including: a driving motor capable of outputting power for driving a driving wheel; a main battery that stores electricity to be supplied to the driving motor; an engine capable of outputting power for driving the driving wheel; a starter motor that starts the engine; an auxiliary battery that stores electricity to be supplied to the starter motor and auxiliaries; a switch of capable of making or breaking an electric coupling between the auxiliary battery and the starter motor, and the auxiliaries and the main battery; and a control apparatus that diagnoses an abnormality in the auxiliary battery. The main battery is coupled to the auxiliaries via a DC-DC converter capable of stepping down a voltage of electricity stored in the main battery. The auxiliary battery is coupled to the auxiliaries via the switch. The controller diagnoses an abnormality in the auxiliary battery with the switch open.
