[0002] Similar to the fuel tank in traditional cars, the power battery is the power source for new energy vehicles and a core component that directly affects the safety of the entire vehicle. The development of battery packs requires careful consideration of various factors, such as the airtightness requirements of the battery box. If the battery box is not properly sealed, external liquids can easily seep in, contaminating the battery's operating environment. It can also lead to acid leakage, causing circuit burnout and affecting driving safety. Therefore, airtightness safety monitoring of the battery box is necessary during production.

[0003] Currently, some airtightness testing devices for battery box covers have insufficient airtightness with the battery box cover, which may prevent the detection of some small cracks, resulting in incomplete airtightness testing of the cover and affecting the safety of battery use.
