PROBLEM TO BE SOLVED: To provide a power storing device for effectively utilization by compensating for the characteristic difference in secondary batteries. SOLUTION: In a power storing device where a plurality of modules 100a and 100b with secondary batteries 110a and 110b are connected in parallel, control means 300a and 300b for calculating the reference values of charging or discharging from charge depth or discharge depth for each of the modules 100a and 100b, and converter means 200a and 200b for adjusting the charged power or the discharged power of the modules 100a and 100b according to the charge depth and discharge depth of the modules 100a and 100b and the difference in the reference values, are controlled by the controllers 300a and 300b, respectively, thus controlling the charged power or discharged power of each secondary battery module. |
