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.

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 to test EVs battery?

3.1 Air tightness test The main method for airtightness testing for EVS batteries is to use a gas pressurization system, connect the product to the airtightness tester by using a quick connector, and then charge the gas into the battery box to be tested. After the air pressure stabilizes, observe the change in internal pressure over time.

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 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.
