The invention provides a power supply system for a vehicle (100), which comprises: a main battery (MB); an auxiliary battery (AB); a DC-DC convertor (31); and a control device (50). The DC-DC convertor (31) can perform bidirectional power conversion between the main battery (MB) and the auxiliary battery (AB). When a preliminarily determined period has passed after a stop command is input to the power supply system, the control device (50) performs charging and discharging control for charging either one of the main battery (MB) and the auxiliary battery (AB) while discharging the other of the main battery (MB) and the auxiliary battery (AB) using the DC-DC convertor (31) on the basis of the results of comparing the charging state of the main battery (MB) with the charging state of the auxiliary battery (AB).
