PROBLEM TO BE SOLVED: To provide an inexpensive power storage system capable of mounting a used power storage device. SOLUTION: A plurality of power storage devices 10A to 10C that communicate using an identifier, a conversion device 20 that converts identifiers of the plurality of power storage devices 10A to 10C, and a conversion device that uses the identifier converted by the conversion device 20. 20 communicates with the plurality of power storage devices 10A to 10C through the power supply 20, converts the DC power output from the plurality of power storage devices 10A to 10C into a predetermined size, outputs the power, and stores the DC power with a predetermined amount of DC power. Charge / discharge control device 30 for charging devices 10A to 10C and DC power output from charge / discharge control device 30 are converted to AC power, and AC power supplied from the distribution system is converted to DC power for charging / discharging. An accumulator comprising an AC / DC converter 40 supplied to the control device 30 and a control device 50 for controlling the charge / discharge control device 30 and the AC / DC converter 40. Electric system. [Selection] Figure 1 |
