PROBLEM TO BE SOLVED: To provide a power supply system that suppresses deterioration of a storage battery in the case of being used at the time of low temperature.SOLUTION: A power supply system according to one embodiment comprises: a first power storage device and second power storage device that store power to be supplied to a load; a power conversion circuit connected between the first power storage device and second power storage device; and a control circuit for controlling charge/discharge of the first power storage device and second power storage device by controlling the power conversion circuit. The control circuit comprises: a drive control unit that when a temperature of the first power storage device is equal to or higher than a threshold temperature, supplies power of the first power storage device to the load and, when the temperature of the first power storage device is lower than the threshold temperature, supplies power of the second power storage device to the load; and a temperature rising control unit that when the temperature of the first power storage device is lower than the threshold temperature, executes temperature rising processing of alternately executing charging from the first power storage device to the second power storage device and charging from the second power storage device to the first power storage device.SELECTED DRAWING: Figure 1
