Background With the rapid development of electric automobiles, the power battery industry is fully excavated and rapidly grown. In order to improve the battery density of the power battery, the state of the art is developing soft-pack power lithium batteries. All the battery monomers are subjected to strict technological processes such as testing, aging, screening and the like before leaving the factory, and the battery testing clamp is used as an indispensable component in the technological process. When designing and producing batteries, it is often necessary to detect various parameters of the produced batteries by using battery test equipment so as to understand the electrical properties of the batteries. In the process of testing the electrical performance of the battery, the contact between the positive electrode lug and the negative electrode lug of the battery to be tested and the test point of the test equipment is very important, and if the contact is not good, the contact resistance can be increased, the accuracy of the test result is affected, and therefore, higher requirements are put forward on the connection between the battery to be tested and the battery test equipment. During testing, the battery to be tested is connected with the battery testing equipment mainly through the clamp, so that information of the battery to be tested is accurately transferred to the battery testing equipment.
