Cycle times for the battery pack test are in the 15 to 500 second range, depending upon the size of the battery and the leak rate. "The in-process test is essential, because a leak in the coolant circuit will not be caught while the cover leak test is being performed," explains Hagyard.
Leak testing plays a critical role in the assembly of battery cells, modules and packs. Batteries need to be leak-free and protected from humidity, water and other liquids for 10 years or more. Reliable leak …
After the test, we can disassemble the battery pack to see if there is water in the battery pack. The insulation resistance value of the water is measured. Air tightness testing. For the battery pack that is off the production line or has been repaired, we can''t do a water immersion test on such a battery pack to test the tightness.
