New Energy Battery Vacuum Leak Detection Solutions

Request a Quote

In new energy battery production — from prismatic and pouch cells to complete EV battery packs — even microscopic leaks lead to moisture ingress, electrolyte dry‑out, and eventual thermal runaway. AIMRSE delivers high‑speed helium mass spectrometer leak detection systems engineered specifically for battery production lines. Our dual‑chamber alternating stations achieve up to 120 units per hour while maintaining 1×10⁻⁹ Pa·m³/s detection sensitivity. The optimized sniffer probe geometry and adaptive helium pressure control reduce tracer gas consumption by 30%, directly lowering operational costs. Each system includes automated pass/fail stamping, barcode traceability, and full data logging to MES. Systems are available for cell‑level testing (cylindrical, pouch, prismatic) and complete pack testing, with tooling designed for rapid changeover. UL/CE certified and SEMI S2 compliant for factory integration.

EV Battery Manufacturing Success Cases

Real throughput and cost improvements from leading US battery plants.

120 UPH Throughput
Prismatic 100Ah Dual chamber

Prismatic Cell Production Line

Michigan, USA

A major EV battery manufacturer needed to increase leak test throughput for their 100Ah prismatic cell line. The existing single‑chamber tester was a bottleneck at 60 units per hour. AIMRSE installed a dual‑chamber alternating helium sniffer system. While one chamber tests, the other is unloaded/loaded, eliminating idle time. The optimized probe geometry reduced helium consumption by 32% while maintaining 1×10⁻⁹ Pa·m³/s sensitivity.

85 UPH Module Throughput
Pouch cells Flexible fixture

Pouch Cell & Module Assembly

Texas, USA

A battery startup producing high‑energy pouch cells for electric aviation needed a leak tester that could handle multiple cell sizes with quick changeover. AIMRSE delivered a flexible sniffer station with adjustable fixturing and programmable test recipes. The system tests individual pouch cells (1×10⁻⁹ Pa·m³/s) and complete 12‑cell modules. Changeover between formats takes under 5 minutes.

60 packs/hr Pack Test Rate
400V pack Helium spray

EV Battery Pack Leak Testing

Nevada, USA

A gigafactory producing battery packs for heavy‑duty electric trucks required a high‑speed helium spray test for each assembled pack. AIMRSE integrated a six‑axis robot that automatically sniffs weld seams, cooling line fittings, and vent valves. Cycle time is 60 seconds per pack with automated pass/fail reporting. The system reduced false rejects by 80% compared to their previous manual spray test.

"We've used the AIMRSE portable helium leak detector for buried pipeline leak testing across Texas. It quickly located a pinhole leak in a 3 km pipeline within four hours, avoiding full excavation and huge costs. The IP54 rugged design and real‑time background compensation work flawlessly in harsh outdoor conditions."

"Our cold storage facility cut annual refrigerant loss from 15% to under 1% thanks to this detector. It found six micro‑leaks among hundreds of fittings, valves and joints. The long‑life hot‑swappable battery, intuitive touchscreen and integrated dry pump make field inspections fast and efficient for our whole team."

"We maintain vacuum furnaces in Ohio and rely on AIMRSE's portable unit daily. It survived drops, rain and 10‑hour shifts without failure. Switching between sniffer and vacuum modes with no recalibration saves hours per job, and built‑in data logging simplifies our reports. It's the best field tool investment we've ever made."

Technical FAQ

What is the typical cycle time for testing a prismatic battery cell?
With our dual‑chamber alternating sniffer system, the total cycle time (including loading, evacuation, sniffing, and unloading) is 30–45 seconds per cell, depending on cell volume and required sensitivity. The evacuation time dominates; for a typical 100Ah prismatic cell, we achieve 1×10⁻⁹ Pa·m³/s sensitivity in 35 seconds. The dual‑chamber design eliminates idle time — one chamber tests while the operator loads/unloads the other, achieving up to 120 units per hour. For pouch cells with smaller internal volume, cycle time can be as low as 20 seconds.
How much helium do your systems consume per cell, and can we reduce it further?
Our standard sniffer systems consume 0.5–1.0 liter of helium per cell at 10% concentration (i.e., 0.05–0.1 liter of pure helium). The optimized probe geometry and adaptive pressure‑of‑helium control reduce consumption by 30% compared to conventional sniffers. For high‑volume lines (e.g., 1 million cells/year), helium cost savings typically exceed $50,000 annually. Further reduction is possible by using helium‑nitrogen mixtures as low as 5% He, though sensitivity decreases logarithmically. We recommend a 10% He mix for best balance of cost and detection limit.
Can your system detect leaks in assembled battery packs with coolant lines?
Yes. For pack‑level testing, we use a combination of vacuum decay and helium spray methods. The pack is evacuated through the service vent, then helium is sprayed externally while a sniffer probe scans weld seams, coolant fittings, and the vent valve. For packs with integrated cooling plates, we can also pressurize the coolant circuit with helium and sniff for external leaks. Our robotic sniffer systems automate the scan pattern, ensuring consistent coverage. Detection limit for pack testing is typically 1×10⁻⁵ mbar·L/s (1×10⁻⁶ Pa·m³/s) due to longer response times from large volumes.
Do you offer integration with battery formation and aging equipment?
Absolutely. Our leak test systems can be integrated into your battery assembly line upstream of formation. We provide a REST API, SQL database export, or SECS/GEM communication to pass test results to your MES. The leak test data can be linked to cell barcodes and used to sort cells before formation. We also offer custom conveyor integration and rejection mechanisms for failed cells. Many customers combine our leak tester with their existing formation racks; we supply the PLC logic to trigger the pass/fail signal.
