Description

TECHNICAL FIELD

[0002] In the field of battery cell production and manufacturing, the insulation voltage performance of the battery cell is a key indicator that determines its quality and safety. There are various types of battery cell insulation voltage test mechanisms on the market, which have played a certain role in ensuring the quality of the battery cell. However, they are generally only capable of performing partial detection tasks and are difficult to meet the needs of comprehensive and high-precision detection.

[0003] Some test mechanisms focus on detecting the insulation performance between the battery cell and the shell by applying a specific voltage between the battery cell and the shell and measuring parameters such as leakage current to determine the insulation condition. However, the internal structure of the battery cell is complex, and in addition to the insulation between the battery cell and the shell, the battery cell itself also needs to be tested for insulation voltage. Detecting only the battery cell and the shell is difficult to find potential insulation problems inside the battery cell, which may cause short circuit failures in subsequent use.

[0004] In particular, many current test mechanisms lack sensitivity to subtle insulation defects on the battery cell body during the detection process. For example, small scratches, pinholes, or partial tightness of the insulation film on the surface of the battery cell, etc. The existing detection means may not be able to accurately identify these seemingly small defects. These seemingly small defects may gradually expand during the long-term charging and discharging of the battery cell, and under mechanical vibration, etc., eventually causing serious insulation failure problems, affecting the service life and safety of the battery cell.
