PROBLEM TO BE SOLVED: To provide a charge/discharge inspection system allowing reduction in contact resistance between a probe unit and a secondary battery.SOLUTION: A charge/discharge inspection system 2 charging and discharging a secondary battery 1 for inspection includes a power unit 3 and a battery inspection unit 4. The power unit 3 includes: a control section 25; a calculation section 26; a master controller 8 controlling the charge/discharge inspection system 2; and a power source 7. The battery inspection unit 4 includes: a probe 11 supplying power from the power source 7 to the secondary battery 1; and connection means establishing and breaking electrical connection between the secondary battery 1 and the probe 11. The calculation section 26 calculates contact resistance between an electrode of the secondary battery 1 and the probe 11. The control section 25 breaks electrical connection between the secondary battery 1 and the probe 11 with the secondary battery 1 being fed with power, when the contact resistance is greater than a predetermined threshold. |
