Aluminum alloy is currently an ideal lightweight material for automobiles. It shines in the field of automobile manufacturing due to its low density, high strength and excellent processability.

New energy vehicles use lithium batteries as their power source, and lithium batteries are the core components of new energy vehicles.A battery module generally includes multiple batteries and an outer frame for placing the batteries.

The stamped aluminum plate around the battery pack serves as sealing protection.

Today I want to share a case about air tightness testing of battery pack stamped aluminum plates.

Testing equipment: HC classic series air tightness tester

Detection method: Use direct detection method, with molds and tooling customized according to customer needs.

Inflate 20Kpa, time 10s, stabilize pressure 30s, test 60s.During this process, if the leakage exceeds the upper limit of 50pa, the program triggers an alarm or an NG signal appears, which means that the air tightness of the aluminum plate is unqualified and it is a defective product.
