Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically a lithium battery testing device. Background Technology

[0002] As battery technology advances, batteries are becoming thinner and thinner, which reduces their rigidity and makes them more prone to softening. Therefore, it is necessary to test whether the battery cells are softening before they leave the factory. In addition, the positive and negative terminals of the battery are easily scratched, so it is also necessary to test the positive and negative terminals of the battery.

[0003] A search revealed that patent application CN213134061U discloses a lithium battery testing device, including an operating platform with a belt drive device. The belt drive device is equipped with belts A, B, and C. A support plate is mounted on belt B, and a lithium battery clamp is fixedly mounted on the support plate. The operating platform is equipped with a testing device bracket, and a testing device is mounted on the testing device bracket. The testing device includes a pressure tester and a telescopic test rod. The testing device is aligned with the lithium battery clamp. The operation process is simple and improves work efficiency.

[0004] However, because the battery clamp is cylindrical, it can only clamp and fix the positive and negative terminals of the battery, which can easily damage the positive and negative terminals and result in poor performance. At the same time, the telescopic test rod can only detect whether the battery cell is soft, but cannot detect the positive and negative terminals, which reduces its functionality and practicality.

[0005] Therefore, we propose a lithium battery testing device. Utility Model Content
