[0001] This utility model relates to the field of new energy power battery packs, specifically to a device suitable for cell testing. Background Technology

[0002] With the development of the new energy electric vehicle market, the testing requirements for new energy battery cells are gradually increasing. Typical battery cell tests include compression and needle penetration tests. During these tests, smoke may be emitted. When smoke appears, the testing personnel may be unable to monitor changes in the battery cell due to obstructed vision, indicating uncontrolled changes. Furthermore, it is necessary to collect and analyze the substances in the smoke when the battery cell is out of control. Therefore, to address this situation, a battery cell testing device is needed that can both collect and analyze the smoke and allow for unobstructed observation of the battery cell's uncontrolled state.

[0003] At present, a device suitable for battery cell testing is proposed to solve the problems mentioned in the background. Utility Model Content
