We cover a wide range of lithium-ion battery testing standards in our battery testing laboratories. We are able to conduct battery tests for the United Nations requirements (UN 38.3) as well as several safety standards such as IEC 62133, IEC 62619 and UL 1642 and performance standards like IEC 61960-3.
The complete battery modules are assembled in a housing and tested for leak rates within the range of 10-3 scc/s. Helium vacuum test or electrolyte tracing for individual battery cells Helium leak detection or decay/ flow test on battery packs components (e.g. on cooling tubes & hoses).
In addition to UN 38.3, there are safety standards such as IEC 62133, IEC 62619 and UL 1642 as well as performance standards, for example IEC 61960-3. WHY IS TESTING FOR BATTERY TRANSPORTATION IMPORTANT? Lithium-ion batteries are now used across a vast range of battery-powered equipment.
3.1 Air tightness test The main method for airtightness testing for EVS batteries is to use a gas pressurization system, connect the product to the airtightness tester by using a quick connector, and then charge the gas into the battery box to be tested. After the air pressure stabilizes, observe the change in internal pressure over time.
If the individual cells are to be combined into larger battery modules – or into battery packs – the tightness of the cooling circuit must be ensured in production. Leak rates within the range of 10-3 scc/s are used when cooling with a water glycol mixture and 10-5 scc/s when cooling with gas.
TÜV SÜD's international network of accredited laboratories offers a wide variety of lithium-ion battery tests and certifications, including: UN 38.3 tests for shipping and battery transportation. More specifically, we offer: For more information about battery transportation testing, please contact us today.
