<p>PROBLEM TO BE SOLVED: To provide a power storage system capable of improving efficiency of charge or discharge by simultaneously charging or discharging a plurality of cartridges, while preventing occurrence of cross flow between respective cartridges.SOLUTION: A power storage system 6 comprises: a plurality of cartridges 100_1 to 100_4 which are connected in parallel and are composed of a plurality of connected cells; and cross current prevention circuits 65_1 to 65_4 for restricting current through each of the cartridges 100_1 to 100_4 in one direction. The power storage system 6 simultaneously charges the plurality of cartridges 100_1 to 100_4 connected in parallel by converting commercial voltage to direct voltage, or simultaneously discharges the plurality of cartridges 100_1 to 100_4 connected in parallel to output the commercial voltage.</p> |
