[0002]
After the battery pack is assembled, it needs to be tested offline, including: safety test, high and low voltage electrical isolation performance test, charge and discharge performance test, and also test battery pack DCR, cell DCR, dynamic pressure difference, temperature rise test, etc. , EOL test, including cell voltage, temperature, and insulation resistance reported by BMS. These test items are required by customers. There are many items and the beat is long.
[0003] The above test items are tested one by one to determine whether the test specifications are reasonable. The entire set of battery pack test items is reported through the BMS DBC. After the equipment is collected, the test specifications are compared and the current test items are qualified. Packages are mistakenly intercepted or flowed out to customers, causing serious security incidents or quality risks
Therefore, it is proposed that a new test method is needed to improve the test cycle, but at the same time, the test can cover all test items
