Detecting test-gas leaks in EV battery production

A leading battery manufacturer for the automotive industry is using test-gas leak-detection systems from Zeltwanger Leak Testing & Automation, which is equipped with complete solutions from Pfeiffer Vacuum.

In electric vehicles (EVs), lithium-ion batteries are used almost exclusively as accumulators and vacuum technology is indispensable for their production.

The proper functioning, quality and safety of lithium-ion batteries depends on their integrity and impermeability to external influences, such as moisture ingress. For this reason, leak-detection systems are used in battery production to check the batteries.

Even the smallest leaks can be quantified and localised with Zeltwanger’s testing systems, making it possible to eliminate them quickly, and make any necessary changes to geometries and production processes.

Together with Zeltwanger, Pfeiffer Vacuum’s team of experts designed solutions tailored to customer requirements.

Pfeiffer Vacuum supplies vacuum solutions from a single source. It offers helium leak detectors from the ASI 35 series, as well as valves, vacuum gauges, DuoLine, Hena and Pascal backing pumps.

“Since our entry into leak testing with helium a few years ago, we have acquired extensive expertise through intensive development work and close cooperation with leading suppliers of key components,” says Markus Mattauch, project manager at Zeltwanger.

“When a customer from the automotive industry enquired about the supply of test-gas leak-detection systems, Pfeiffer Vacuum was our first choice.”
