Below are two of the key challenges you are likely to encounter with battery pack leak testing and strategies to overcome them. Any kind of test that builds pressure (with air) inside the pack can cause the volume to expand like a balloon, which will increase the measured leak rate.
Testing battery packs for leaks is a critical safety step for automakers. Due to material instability, any test that uses air to build pressure inside the pack can cause the volume to expand like a balloon, increasing the measured leak rate.
Leak testing electric vehicle battery packs is often more challenging than any tests performed at the component or subassembly level, due to the myriad of factors at play. In this blog post, Chuck Hagyard discusses these challenges and how to overcome them for an effective leak test.
For this new market, battery leak testing is essential for electric vehicles, for battery packs any leakage can compromise safety, performance, and longevity of the system.
Manufacturers must also determine if they are going to test with a positive or negative (vacuum) pressure within the pack. Without question, leak testing an EV battery is one of the most challenging applications that any leak test company will tackle.
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.
