\"LEAK<\/p>\n

Leak testing of battery cells<\/h2>\n
\n

Whether cylindrical, prismatic or in pouch form, we offer suitable solutions for reliable leak testing of battery cells<\/strong>. Depending on the requirements, various test methods such as helium vacuum leak testing or the electrolyte detection method are used.<\/p>\n

Renowned battery cell manufacturers rely on ZELTWANGER\u2018s leak testing technology \u2013 from prototype testing to mass production.<\/p>\n<\/div>\n

Leak testing of battery modules<\/div>\n
and components<\/div>\n<\/h2>\n
\n

A battery system, consists of many individual components and assemblies that have to be checked for leaks. This includes battery modules<\/strong>, the cooling system, high-voltage connectors, pressure compensation elements (DAE), and enclosure components such as the battery tray, the battery cover, and other attachments. We also offer the appropriate leak testing solutions using air and tracer gases for these components.<\/p>\n<\/div>\n

Leak testing of battery packs<\/h2>\n
\n

Mounted battery packs<\/strong> must meet the highest requirements for leakage. The end-of-line test ensures that no leaks remain undetected before the pack is installed in a vehicle. Depending on the size of the component, the required cycle time, and the leak rate, different testing methods are used, such as the mass flow method, as well as accumulation or sniffing tests with helium. With the sniffing test, leaks can be pinpointed precisely using a manually or robotically guided probe.<\/p>\n<\/div>\n
