The power battery system (battery pack) is the core energy source that provides driving power for new energy vehicles and is one of the most critical components of new energy vehicles.

The main function of the battery pack shell is to carry the battery pack, electrical module, cooling module and other power battery system components, while protecting the battery and electrical system from damage when the vehicle is subject to external collision, impact and extrusion.

Therefore, the pressure resistance and sealing performance of the battery pack shell must meet relevant requirements.

Today we are sharing aboutBattery pack shell air tightness testingIn this case, the air tightness can be tested not only for its pressure resistance but also for its sealing.

Testing instrument: HC classic seriesAir tightness detector

Detection method: Customize dual-channel jigs and tooling according to the structure of the battery pack shell and customer needs.

Using the direct pressure air tightness test method, put the product to be tested into the mold, press the start button of the tooling, and start the test.The negative pressure is -30Kpa, the inflation time is 15s, the pressure is stabilized for 15s, the test time is 20s, and the upper limit of leakage is 50pa.During the test, if the leakage value exceeds the set leakage value, the product to be tested is a defective product, otherwise it is a qualified product.

Hai RuisiAir tightness testing equipmentincome:
