Global Helium Leak Detector for Power Battery Market Strategic Research Report

Scope of the Report

The global Helium Leak Detector for Power Battery market size is predicted to grow from US$ 60.46 million in 2025 to US$ 97 million in 2032; it is expected to grow at a CAGR of 7.1% from 2026 to 2032.

A helium leak detector for power battery is a precision testing instrument used to detect micro-leaks in EV power battery cells, modules, packs, covers, weld seams, safety valves, cooling plates, and sealing structures by using helium as a tracer gas. It is mainly applied to lithium-ion power batteries, including prismatic, cylindrical, pouch, and blade-type cells. Power battery sealing quality is critical because leakage may cause electrolyte loss, moisture ingress, corrosion, capacity degradation, swelling, or safety risks. Helium leak detection is widely used in cell production, laser welding inspection, module assembly, pack sealing, and end-of-line quality control.

Global production capacity is approximately 8 thousand units.

In 2025, global sales reached approximately 3 thousand units, with an average price of around KUS$ 20.6 per unit, gross margin around 48%.

The helium leak detectors for power batteries represent a high-growth application within the leak detection equipment market. Their demand is strongly supported by EV production expansion, battery safety standards, and the need for reliable, traceable quality control. Compared with pressure decay or visual inspection methods, helium leak detection offers higher sensitivity and better ability to identify micro-leaks in cells and battery components. Although helium cost, equipment investment, and system integration complexity remain challenges, the technology remains important for high-end power battery manufacturing. Future growth will focus on faster testing, lower helium consumption, automation, helium recovery, and integration with smart battery production lines.

Market Trend

The power battery helium leak detector market is developing toward automation, high-speed testing, dry-pump systems, helium recovery, and production-line integration. Battery manufacturers increasingly require customized leak detection systems for different cell formats, large battery packs, cooling plates, and thermal management components. Demand is rising for vacuum chamber testing, accumulation testing, automatic loading and unloading, robotic handling, data traceability, and MES connection. As EV battery factories expand, leak detection equipment is shifting from standalone instruments to complete automated testing stations. Future products will emphasize faster cycle time, stable sensitivity, lower helium consumption, clean operation, and flexible compatibility with multiple battery designs.

Market Drive

The main drivers of helium leak detectors for power batteries are the rapid growth of electric vehicles, stricter battery safety requirements, and increasing demand for high-reliability sealing inspection. Power batteries operate under complex thermal, vibration, and charging conditions, so small leaks may lead to moisture ingress, electrolyte leakage, internal corrosion, reduced service life, or thermal safety risks. Higher energy density battery designs also raise the importance of precise leak testing. In addition, large-scale battery production requires fast, repeatable, and traceable quality inspection. This supports demand for automated helium leak detection systems in cell manufacturing, module assembly, and battery pack production.

Upstream and Downstream

The upstream supply chain includes helium mass spectrometer modules, dry vacuum pumps, turbomolecular pumps, valves, pressure gauges, helium sensors, vacuum chambers, sealing fixtures, automation modules, PLC systems, robotic handling systems, software, hoses, fittings, and helium gas suppliers. Key upstream companies include vacuum equipment suppliers, sensor manufacturers, precision machining firms, automation equipment providers, and industrial gas companies. Downstream customers mainly include power battery cell manufacturers, EV battery pack producers, automotive OEMs, energy storage companies, battery equipment integrators, cooling plate manufacturers, and R&D laboratories. These users apply helium leak detectors for cell sealing inspection, weld quality validation, pack airtightness testing, and failure analysis.
