The present invention relates to a charging/discharging probe capable of correctly determining whether or not charging and discharging of a secondary battery are stably performed. According to the present invention, the charging/discharging probe comprises: a tubular body having a vertically penetrated unit in the inside; a charging/discharging body which includes a penetrated unit formed to be vertically penetrated in the inside, a charging/discharging connector coupling unit installed in an upper part and connecting to a current line to apply current, and a sensing connector coupling unit connecting to a sensing line to measure a contact resistance of a charged/discharged unit, is inserted into the penetrated unit of the tubular body, and makes contact with an electrode of a secondary battery; an elastic support body installed between the tubular body and the charging/discharging body; a voltage measure tool separating an outer surface from an inner surface of the penetrated body of the charging/discharging body while being inserted into the penetrated body of the charging/discharging body and making contact with the electrode of the secondary battery; a charging/discharging connector which includes a fixing nut installed to be vertically movable in the charging/discharging connector coupling unit of the charging/discharging body, and a connection nut installed to be vertically movable in the charging/discharging connector coupling unit of the charging/discharging body and placed in an upper part of the fixing nut; and a sensing connector detachably coupled with the sensing connector coupling unit of the charging/discharging body to couple the sensing line with the charging/discharging body. |
