BATTERY LEAK TESTING
EV BATTERY LEAK TESTING
Leak Detection Equipment for EV Batteries
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 with an F620.
For battery leak testing of the cell, ATEQ presents the new patented B28 testing method which offers a safe low ionization voltage to ionize oxygen molecules in the air around the battery cell. If there is a leak in the battery insulation, ionized oxygen molecules will be able to flow through the hole and the ions will connect to the inside of the battery cell, without igniting it.
Efficient Leak Testing for Battery Production
The B28 can be integrated into production lines for fast pass/fail cell testing, with faulty cells sent to a rework bench where the Ioniq wand pinpoints leak locations. After cells pass ionization tests, they are assembled into modules, packs, and trays—each requiring specific leak tests.
ATEQ’s F620 uses differential pressure decay to test battery packaging by sealing openings, injecting compressed air, and measuring pressure drops to identify leaks. For more on our battery leak testing solutions, refer to our Battery Brochure or contact us to speak with an expert.
