A power supply system for a vehicle includes: a first battery (50); a second battery (60) having a capacity and an internal resistance larger than those of the first battery (50); a charging device (450) receiving electric power from outside the vehicle and charging the second battery (60); an auxiliary machinery driving device (800) using electric power of the first battery (50); a converter (10) configured to be capable of supplying, to the first battery (50), a part of the electric power with which the charging device (450) charges the second battery (60); and a control device (100) controlling the charging device (450) and the converter (10) such that a state of charge of the first battery (50) is maintained at a target value, when the auxiliary machinery driving device (800) is operated in a case where the charging device (450) charges the second battery (60). As a result, there can be provided a power supply system for a vehicle capable of appropriately performing charging of the power storage devices and driving of the auxiliary load. |
