Abstract
A charging/discharging device performs charging and discharging on a plurality of secondary cells concurrently in parallel, without adopting a power source having an extremely high current supply capacity. A plurality of switching units controlled by a switching control unit are interposed respectively between the secondary cells and each of a plurality of charging power lines and discharging power lines. A power unit applies voltages having mutually-different voltage values and the switching control unit controls switching so that the respective secondary cells are connected cyclically in predetermined order to the charging and discharge power lines.
