Jig for battery charging and discharging test

A jig for a battery charging and discharging test includes a first frame and a second frame which are disposed in parallel to each other so as to be spaced apart from each other. Two mounting rails are installed to protrude forward to connect the first and second frames, and have slit grooves open in directions facing each other. Each have an open side, such that the battery pack is mounted on the mounting rails through a rail-type structure. An anode unit and a cathode unit are arranged on either side of the mounting rails, and brought into contact with a first terminal and a second terminal of the battery pack coupled to the mounting rails, respectively. The jig can fix a battery at various angles to flexibly cope with various test environments, in order to perform a battery charging and discharging test.
