PROBLEM TO BE SOLVED: To provide a power supply system and power supply control device capable of supplying power to a load in the case that a commercial power source is interrupted.SOLUTION: A power supply system 1 comprises a first power storage unit 21, a second power storage unit 22, a voltage conversion unit 23, and a control unit 27. The first power storage unit 21 discharges to supply power to a load, when a commercial power source is interrupted. The voltage conversion unit 23's input side is connected to the second power storage unit 22. The voltage conversion unit 23 supplies power stored in the second power storage unit 22 to the load, when the commercial power source is interrupted. The control unit 27 controls the voltage conversion unit 23 so as to adjust voltage, in order that adjustment of voltage output from the voltage conversion unit 23 makes the ratio of a value of current supplied from the first power storage unit 21 to the load to a value of current supplied from the voltage conversion unit 23 to the load be a predetermined ratio. |
