Abstract

The invention provides a clamp for a battery charge-discharge test. The clamp is provided with a pedestal and an upper cover. A plurality of positioning grooves are arranged in the pedestal. Negative pole connecting sheets are arranged at the bottom ends of the positioning grooves. A plurality of positive pole contacts are arranged on the lower surface of the upper cover. When using, batteries are inserted into the positioning grooves vertically and the negative poles of the batteries press against the negative pole connecting sheets. Then the upper cover is arranged above the positioning grooves and the positive pole contacts press against the positive poles of the batteries inserted in the positioning grooves. In this way, performance parameters such as voltage characteristics and the like of the batteries can be tested. Since the batteries are inserted in the positioning grooves when the clamp provided by the invention is in use, battery inclination is avoided during the testing process, so that problems of battery inclination and pole short circuit due to insecure clamping of the batteries in the prior art are avoided.

Description

technical field [0001] The invention belongs to the field of battery testing devices, and in particular relates to a fixture for battery charging and discharging testing. Background technique [0002] In the prior art, wire welding or probe test fixtures are generally used for testing cylindrical batteries. Among them, the wire welding method is relatively simple to operate, just use the electric soldering iron and tin wire to weld the positive and negative electrodes of the battery and the wires together. But its disadvantage is that since the shell of the cylindrical battery is generally charged, and the soldering iron and tin wire used for welding are both conductors, a little carelessness when welding the positive lead will lead to the connection between the shell and the positive electrode. , so that the positive and negative poles of the battery are short-circuited, and there is a great potential safety hazard. [0003] Probe test fixture is a kind of battery test de...
