Description

Battery test fixture and battery test frame Technical Field The application relates to the technical field of battery testing, in particular to a battery testing clamp and a battery testing frame. Background In the related art, a clamp commonly used for testing the battery performance is a four-wire ejector pin type, but when the ejector pin type clamp tests high-rate charge and discharge, the clamp has the problems of large heating value, low charge and discharge efficiency, large measurement error and the like due to large contact resistance. In order to solve the problem of larger contact resistance between the ejector pin and the battery, a mode of welding palladium plates at the positive electrode and the negative electrode of the battery is adopted at present, and then the palladium plates are connected with OT terminals of the power line for testing, namely the battery to be tested is directly borne by the power line. It can be understood that although the problem of overlarge contact resistance is solved by the test mode, in the test process, the power lines are easy to generate various irregular bends, so that the arrangement positions of the battery to be tested and the power lines are disordered, the wiring of the whole test operation table is disordered, and even the problem of short circuit with the power lines tested by other groups is caused.
