[0002] In recent years, the new energy vehicle industry has developed rapidly. The battery system is the core component of new energy vehicles, and the battery pack is the main carrier of the battery system. Its working environment requirements are relatively harsh. The complex driving environment brings challenges to the battery system, which in turn affects the key indicators of the vehicle such as cruising range and safety. In order to ensure the reliability of the battery system, mandatory testing is required before the battery pack is finalized.

[0003] Battery safety testing is mainly carried out through overcharging, short circuiting, extrusion and other methods. As long as the battery does not catch fire or explode during the test, it is fine. The extrusion test is to place the fully charged battery on a flat surface and squeeze it. Once the extrusion pressure reaches the maximum, the extrusion is stopped. The battery does not explode or catch fire during this process.

[0004] During the extrusion test of the battery, the battery needs to be clamped by a clamping mechanism to prevent the battery from shaking during the test. During the test, it basically relies on manual fixation, which is not flexible enough and cannot be fixed quickly, thus reducing the efficiency and effect of the clamping mechanism, resulting in poor practicality.
