Abstract
A power supply system includes power circuit which connects first and second batteries with a drive motor, and a management ECU which controls transfer of power between the batteries and the drive motor. The management ECU limits the output power of the second battery to no more than a second output upper limit, during combined output travel which drives the drive motor by way of the combined output of the first and second batteries. In addition, the management ECU sets the second output upper limit to a second maximum output of the second battery in the case of the first SOC of the first batter being greater than a remaining amount warning threshold, and sets the second output upper limit to a range extending upper limit which is smaller than the second maximum output, in the case of the first SOC being less than the remaining amount warning threshold.
