High Precision Vacuum Helium Mass Spectrometry Leak Tester For EV Power Battery Housing | Professional Auto Parts Test Equipment

Safety is the core lifeblood of new energy electric vehicles. HeJin independently develops and manufactures high-precision EV power battery housing helium leak detection equipment, which is the most reliable sealing quality inspection solution for EV battery safety production. As a genuine original source factory of Auto Parts Test Equipment, we provide stable ultra-fine micro-leak detection, fully automatic production line matching, thoughtful pre-sales technical planning and lifelong reliable after-sales service. Our equipment effectively avoids electrolyte leakage, moisture intrusion and thermal runaway hidden dangers, fully complies with global automotive safety standards, and escorts the long-term stable operation of global EV power battery products.

Tiny invisible leaks on power battery shells will directly lead to battery capacity attenuation, accelerated aging, short circuit faults and even serious safety accidents. Traditional water immersion testing and differential pressure testing cannot capture micron-level micro leakage, which cannot meet the strict sealing requirements of modern new energy vehicle power batteries.

HeJin EV power battery housing helium leak detection machine adopts internationally mainstream vacuum chamber helium mass spectrometry detection technology. Using inert helium with small molecular diameter as tracer gas, it accurately captures extremely small leakage points that conventional equipment cannot detect. The whole process is intelligent and automatic, with stable test repeatability, support MES data interconnection and full product quality traceability.

As a professional R&D and manufacturing enterprise focusing on Auto Parts Test Equipment, HeJin provides customized fixtures, parameter optimization and automatic production line linkage one-stop services. Our machines are widely used in EV battery PACK factories, battery shell processing plants and global auto parts testing institutions, helping customers improve production quality, reduce defective product rates and smoothly pass international export certification.
