[0002] At present, the application of lithium batteries has become more and more extensive. Compared with traditional batteries, they have the advantages of large capacity, high operating voltage, fast charging speed, wide operating temperature range, long cycle life, small size and light weight. Because soft-pack batteries have a greater capacity advantage than cylindrical and square batteries, more and more soft-pack lithium batteries are used as energy storage devices and power devices. In the production and testing process of soft-pack batteries, it is necessary to perform insulation testing between the top sealing edge and the pole ear of the soft-pack battery, that is, edge voltage detection.
