Customer ServiceTesting Methods with Air: Mass Flow Method: The mass flow method is based on measuring the volume of flowing air (the mass flow) instead of a pressure drop and is a proven method for leak testing battery trays, covers and complete assemblies.
Fundamental Approach to Contacting: Selecting appropriate contact methods is crucial for conducting leak testing effectively and accurately. Utilizing the Later Electrical Interfaces: A proven approach is to use the existing electrical interfaces of the batteries for testing. This minimizes the effort and increases efficiency.
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).
Battery Housings: Battery housings typically need to have a substantial volume to achieve the required energy density as well as the capacity for the demands of electric vehicles. This means that the volumes of battery housings can be considerable, making leak testing more complex.
In summary, leak testing individual components of a battery system, and complete battery assemblies and housings is a critical step in the development of electric vehicles. It contributes to ensuring the reliability and safety of these vehicles, enabling consumers to fully realize the benefits of electromobility.
