PROBLEM TO BE SOLVED: To provide a charge/discharge device capable of sufficiently preventing another secondary battery from generating heat by stopping the application of a current when one secondary battery is generating heat.SOLUTION: In a charge/discharge device 1, a charge/discharge unit 20 is attached to a charge/discharge jig 2 by being linked thereto with a return spring 15 so as to be able to slide in the lamination direction of a secondary battery 5. The charge/discharge unit 20 is provided with a profiling tooth 23 inserted between spacers 35 for positioning relative to the secondary battery 5 and formed with low incombustibility material, the profiling tooth 23 being inserted between the spacers 35, and the charge/discharge unit 20 is displaced leftward relative to the charge/discharge jig 2, thereby causing the return spring 15 to elongate. Then, charging/discharging to and from the secondary battery 5 is performed while the leftward elongation of the return spring 15 is maintained to be larger than a distance between the right-side end part on contact face of a terminal 6 and the left-side end part at charge time of a charge/discharge probe 24. |
