How do you test a battery with air?

Testing 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.

Is the battery packaging airtight?

If the leak rate is within testing specifications, the battery packaging is airtight. ATEQ accompanies its customers in their production and assembly process of batteries for electric vehicles. We manufacture and supply the equipment that allows you to perform all the tests you need, such as : Battery charging.

How do you conduct a battery leak test?

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.

Why is a battery leak test important?

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.

Why is battery leak testing so difficult?

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.

How does ATEQ test a battery?

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.
