The present invention relates to a charging/discharging device for a secondary battery, which is capable of charging a plurality of batteries at the same time by using tray, whereas a plurality of batteries is mounted. The charging/discharging device according to an embodiment of the present invention comprises: a charge/discharge unit to charge and discharge while gripping electrode leads of the secondary battery (rechargeable battery lead surface) with first and second grippers arranged side by side, wherein a first electrode lead and a second electrode lead are formed on one end of the secondary battery; a tray unit including a socket wherein a first electrode lead of the secondary battery lead is fitted on, a connection bridge wherein multiple sockets are electronically connected, at least one extension terminal electrically connected to the sockets electrically connected by the connecting bridge, in order to hold a secondary battery (double-sided lead battery) having one end with the first electrode lead and the other end with the second electrode lead. The first electrode leads respectively provided on the plurality of double sided lead secondary batteries are all fitted to each of the sockets, the second electrode leads respectively provided on the plurality of double-sided lead secondary batteries are gripped by the second grippers respectively, so that charging and discharging all the double sided lead secondary batteries can be performed while at least one extension terminal is gripped by the first gripper. |
