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.

Why is battery leak testing important?

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.

What happens after a battery ionization leak test?

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.

How do ATEQ differential pressure decay leak testers work?

ATEQ differential pressure decay leak testers, like the F620, can test the battery packaging by sealing off the packaging openings and injecting the package with compressed air, measuring the pressure and measuring how much the pressure drops, which would signify a leaking battery pack.

How does DNC improve the accuracy and reliability of leak testing systems?

DNC is designed to enhance the accuracy and reliability of leak testing systems by minimizing the impact of background noise and external factors on test results. In leak testing applications, background noise, such as atmospheric air movement, machinery, or ambient environmental conditions, can interfere with the accuracy of the test results.

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.
