Leak test
in battery technology
The lithium-ion battery is the powerhouse behind electromobility and therefore not only forms the heart of the drive system in battery electric vehicles (BEV) and plug-in hybrids (PHEV), but is also an integral component of fuel cell vehicles. The buffer battery stores the electrical energy from the fuel cell and uses it to supply the electric motor. The battery is therefore also of great importance in fuel cell electric vehicles (FCEV).
Maximum tightness for safe, long-lasting batteries
Mandatory leak test: for every cell shape and every application
Test methods at a glance: Helium vacuum, sniff test & more
Various methods of leak testing are available, such as helium vacuum leak testing for battery cells or cooling units and thermal management components. The tightness of battery housings (battery packs) can also be tested using a fully automated helium sniffer test.
Safe end-of-line testing: leak testing without helium
During the production process, a battery cell filled with electrolyte and finally sealed can no longer be tested for leaks using the helium-vacuum method. This risk is reduced to a minimum by a final inspection (EOL = end-of-line test). Here, the battery cell is checked for leaks in a vacuum chamber, without helium, but by detecting escaping solvent in the event of a possible leak in the battery cell.
Application examples
- Fully automatic helium vacuum leak test of assembled battery cells
- Fully automatic and semi-automatic helium vacuum leak testing of battery cell components
- Fully automatic helium sniffing of battery housings
- Worker-independent and
fully automatic gas bubble detection in the water bath using ultrasound from battery housings - Helium testing of the thermal management cooling element

Application examples From practice
In the age of e-mobility, battery electric drives are becoming increasingly important on our roads and almost all well-known car manufacturers offer hybrid or fully electric vehicles. And many new suppliers of battery electric vehicles are entering the market.
The battery plays the central role in electromobility, but also in stationary applications, and requires special quality standards.
