The power supply unit includes a lead secondary battery (first battery) that is capable of being charged with power generated by an alternator (power generator); a lithium secondary battery (second battery) that is electrically connected in parallel to the lead secondary battery, capable of being charged with power generated by the alternator (power generator), and has higher output density or higher energy density than the lead secondary battery; and a switching means that is electrically connected between the alternator and the lead secondary battery, and the lithium secondary battery, and switches between conduction and blocking. The switching means is configured by a plurality of MOS-FETs (semiconductor switches) being connected in series such that respective parasitic diodes present in the semiconductor switches face opposite directions.
