With the improvement of new energy vehicle range and the widespread adoption of high-voltage platforms, battery pack protection levels have been upgraded to IP68. Within a 10-year lifecycle, moisture ingress, internal gas generation, and weld leakage can all trigger thermal runaway risks. Leading automakers have now abandoned the single airtightness sampling inspection model and adopted a triple inspection combination: first, differential pressure airtightness pre-screening to batch-remove major leak defects; second, helium mass spectrometry precision re-inspection to pinpoint micro-leak locations; third, 3D vision scanning for weld and shell assembly appearance defects. The entire inspection data set is connected to the vehicle traceability platform to meet national power battery full-lifecycle regulatory requirements. Testing solution providers also supply high-low temperature cycle retest fixtures to simulate extreme vehicle operating conditions and verify sealing reliability.
We tailor-make power battery PACK airtightness, helium leak, and visual triple inspection solutions, adapting to automakers' high-standard quality control requirements, supporting operating condition simulation testing and full-process data traceability, and ensuring safe and stable operation of battery packs.
