Description

Technical Field

[0001] The utility model relates to the technical field of insulation testing, in particular to an automatic insulation testing tool for a battery core. Background Art

[0002] The insulation withstand voltage tester is a device that performs insulation strength tests on various high-voltage electrical equipment, electrical components, and insulating materials under power frequency or DC high voltage. The insulation withstand voltage tester is a general-purpose AC safety tester suitable for safety tests of household appliances and low-voltage electrical appliances. The leakage current value is adjusted by the coarse and fine adjustment knobs. When the leakage current exceeds the tolerance, the test voltage is automatically cut off and an audible and visual alarm signal is issued.

[0003] In the manufacturing process of lithium-ion batteries, after the production of the pole pieces is completed, the positive and negative pole pieces and the diaphragm are assembled together by winding or stacking, and the diaphragm separates the positive and negative pole pieces. During the battery charging and discharging process, the diaphragm isolates the electron conduction between the positive and negative pole pieces, while allowing lithium ions to pass through. After winding, the pole piece and the diaphragm are more closely fitted to reduce the resistance to lithium ion transmission. The battery cell is often subjected to an insulation withstand voltage test, which is mainly used to determine whether there are foreign particles inside the battery cell that cause a short circuit. The existing test tooling requires testing one by one, which is slow, cumbersome and inefficient. Utility Model Content
