Claim:
1. A charging/discharging device which causes a plurality of charge/discharge members to perform, concurrently in parallel, charge operation and discharge operation, comprising: a power unit; a plurality of power lines for charging to provide, to the plurality of charge/discharge members, electric power supplied from the power unit; a plurality of power lines for discharging to provide, to the power unit, electric power discharged from the plurality of charge/discharge members, the power unit applying voltages having a plurality of mutually-different voltage values via the plurality of power lines for charging and the plurality of power lines for discharging; a plurality of connection switching units which switch connection of the plurality of charge/discharge members with the power lines for charging and the power lines for discharging as being interposed respectively between the plurality of charge/discharge members and each of the power lines for charging and the power lines for discharging; and a switching control unit which controls switching of connection of the plurality of connection switching units so that the respective charge/discharge members are connected cyclically in predetermined order to the plurality of power lines for charging and the plurality of power lines for discharging; and wherein the switching control unit switches connection of the plurality of connection switching units at timings defined by dividing one cycle time for cyclic connection with the plurality of power lines for charging and the plurality of power lines for discharging by a total number of the charge/discharge members.
