Managing Complexity in Battery Pack Production
Detecting Hidden Risks Early to Protect Quality, Safety, and Throughput

Battery pack production brings together cells, electrical connections, cooling systems, and mechanical structures into a safety critical system. Increasing energy density, higher system voltages, and growing design diversity add complexity at every stage. At the same time, manufacturers face strong pressure to scale output, reduce cost, and ensure consistent quality across high volumes.
Small process deviations can lead to leaks, electrical faults, or thermal management issues that are often difficult to detect once the pack is fully assembled. Identifying risks early and maintaining process control is therefore essential.

Rigorous leak testing at every joining and sealing interface—catching defects before full integration, when they're cheapest to fix.
Leak-tight cooling circuits, tested below conventional detection limits so nothing surfaces later, when fixes cost the most.
Leak-tight housings keep moisture out from the start, protecting against corrosion and electrical faults before units leave the line.
Flexible, fast leak testing that adapts to growing pack variants, and targeted testing to fill gaps where automation can't reach.
Leak detection as an enabler for stable pack production
Leak detection supports battery pack production by making hidden defects visible early. When leaks are identified before final assembly or system integration, corrective actions can be taken with significantly lower cost and risk. This improves yield, protects downstream processes, and increases transparency across production data.
Rather than acting only as a final quality gate, leak detection can be integrated as a process control element at critical assembly and integration steps.

Detect electrolyte leaks in battery modules and packs early, before they impact safety, yield, or downstream value. ELT Vmax supports fast, inline leak testing with high sensitivity, helping you stabilize battery pack production without slowing down throughput.

Micro-defects can slip past initial leak testing. BES4000 localizes electrolyte leaks down to the cell level, so you fix the exact problem, fast.

IP67 defines water ingress resistance, but it does not specify which helium leak rates ensure compliance in production. This application note shows how water ingress behavior correlates with measurable helium leak rates, helping you define practical test limits for reliable IP67 verification.

Helium costs and availability are putting increasing pressure on leak testing operations. This article shows how you can significantly reduce helium consumption without sacrificing sensitivity or throughput, by adapting tracer gas concentration, calibration strategy, and recovery methods.

Setting the right leak rate specification is critical to protecting your product, your users, and your compliance targets. This article helps you translate real application risks, operating conditions, and failure scenarios into practical leak rate limits, so you can test with confidence and avoid costly over- or under-testing.
