Ensuring leak-tight lithium battery packs is critical for electric vehicle safety, battery longevity, and manufacturing quality. HeJin's High-Sensitivity Helium Leak Testing Machine is specifically engineered for precision leak localization of lithium battery PACK assemblies using helium as the tracer gas.
Unlike conventional pressure decay methods that only indicate whether leakage exists, this system accurately identifies the exact leak position through an advanced helium accumulation chamber and helium mass spectrometer probe. Manufacturers can quickly locate leakage points, reduce rework time, and improve production yield.
Designed and manufactured by HeJin, a professional source manufacturer of leak testing equipment, this solution combines reliable engineering, user-friendly operation, and stable long-term performance for modern battery production lines.
The HeJin Lithium Battery Pack Helium Leak Testing Machine adopts the Accumulation Chamber + Helium Probe Detection Method.
During testing, helium is filled into the battery pack under controlled pressure. If leakage exists, helium escapes into the accumulation chamber and mixes evenly with the surrounding air. A highly sensitive helium mass spectrometer probe then scans the chamber, accurately detecting and locating the leakage point.
Compared with conventional air leak testing methods, helium leak testing offers significantly higher sensitivity, making it ideal for new energy battery manufacturing, automotive components, refrigeration systems, electronic products, and precision sealed assemblies.
Its compact structure, flexible parameter settings, and reliable detection capability enable manufacturers to establish a standardized leak testing process while reducing false judgments and improving product consistency.
Capable of detecting leak rates as low as 1E-3 mbar·L/s, allowing manufacturers to identify extremely small leakage paths before products leave the factory.
Instead of only determining pass or fail, the helium probe accurately pinpoints the leakage location, making repair faster and more efficient.
Helium charging pressure and concentration can be configured according to different battery pack designs and production requirements.
Compact footprint allows easy integration into existing production lines or laboratory environments.
Noise level remains below 70 dB, creating a comfortable working environment.
