1. A jig for a battery charging and discharging test, comprising:
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 installed to protrude forward, configured to connect the first and second frames, and having slit grooves which are open in directions facing each other and each have an open side, such that the battery pack is mounted on the mounting rails through a rail-type structure; and
an anode unit and a cathode unit which are symmetrically arranged to face each other with the mounting rails in between, such that the pairs of anode and cathode units are placed in parallel to each other, and brought into contact with a first terminal and a second terminal of the battery pack coupled to the mounting rails, respectively,
wherein the anode units and the cathode units are cross-arranged to face each other with the mounting rails in between, and also face each other in a direction parallel to the mounting rails, and the pairs of anode unit and cathode unit facing each other with the mounting rails in between can be moved individually in a direction away from or closer to the neighboring the cathode unit and the anode unit, respectively.
