CHARGING-DISCHARGING SYSTEM FOR BATTERY

PROBLEM TO BE SOLVED: To provide a charging-discharging system for a battery, which can enhance productivity of the battery by enabling it to house a lot of battery pouches in a limited space to the maximum, and by making the electrical contact between an electrode and an electrode contact part stably maintained. SOLUTION: This includes a battery insertion part 33, where many battery insertion ports 30 are formed to get the battery pouches 17 inserted and where holes through which electrodes 20 of the battery pouches 17 can pass are formed at the bottom, and includes a tray 25 equipped with a frame 26 which surrounds the ends of the battery insertion part 33. This is further equipped with clips 60 for electrode contact, which has leaf springs 55 facing each other so as to hold the electrodes 20 protruding through the bottom face hole of the battery insertion part 33 and supportings 56 to support the leaf springs 55.
