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.
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.
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.
ATEQ has a variety of methods to leak test batteries throughout the production process. Leak testing electrical vehicle battery cells, for example, begins with an ionic leak test of the battery cell pouch and ends with pressure leak testing the entire battery tray.
After the battery cells pass the ionization leak test, the next phases are putting several cells together to create a battery module, combining the modules into a battery pack then putting several battery packs together into a battery tray. Each of these battery packages requires leak testing.
Leak testing battery cells and housings requires specialized methods and adaptation to individual requirements. Despite the lack of standardization in the industry, the mentioned approaches and techniques are crucial to ensuring the safety and reliability of electric vehicles.
