A vehicle (1) includes a plurality of chargeable and dischargeable batteries (B1, B2), a load device, a bus for supplying electric power to the load device, a plurality of voltage step-up converters (12-1, 12-2) provided in association with a plurality of batteries (B1, B2) respectively, a charging line (PCL) for supplying electric power provided from outside the vehicle to a connection point of the first battery (B1) and the first voltage step-up converter (12-1), and a control device (30). When charging from an external source is started, the control device (30) causes the first voltage step-up converter (12-1) to perform a rectifying operation for supplying electric current from the charging line to the bus in a case where a voltage of the bus is lower than a voltage of the charging line, and causes the first voltage step-up converter (12-2) to connect the bus and the second battery (B2).
