Since the power battery pack or system is in a sealed state and has a large size, there is a certain resistance and buoyancy during the falling process after entering the water, and the uneven stress will cause the falling speed of the power battery pack or system to be uncontrollable, and the horizontal position to be uncontrollable and inclined, so a certain counterweight is needed during the test. However, due to the particularity of the battery pack shell, the counterweight directly pressed on the shell may cause deformation of the shell.

[0004] Due to the large weight of the power battery pack or system, it needs to be hoisted during the test. Directly hoisting the mounting screw holes at the four corners of the power battery pack or system will cause the lifting rope to deviate during the lifting process, and the uneven stress on the lifting eye of the power battery pack or system at the four corners will cause the deformation of the hoisting position and lead to the risk of water leakage. In addition, due to the diversification of the size of the power battery pack or system, different sizes of tooling and reasonable counterweight need to be processed according to different sizes and weights of the power battery pack or system, which not only increases the cost, but also increases the workload.

[0005] Therefore, it is necessary to develop and design a battery immersion test tooling that not only meets the requirements of power battery pack or system immersion test, but also adjusts the counterweight, installation size and meets the hoisting requirements. Invention content
