3 FAQs about [Battery cabinet housing air tightness]
How to test a sample battery housing?
The leak test of the sample battery housing is carried out using two different measuring methods. First, the pressure decay test is also performed here. The integral limiting leakage rate for the sample battery housing is set at 6 ml/min. It is based on a series battery housing with a known leakage rate.
What is the limiting leakage rate of a battery housing?
Since the joints for the battery housing must be tight against the entrance of water or water vapor, the limiting leakage rate for the laboratory-scale test sample is set at 10-3 mbar*l/s or 0.06 ml/min [ 8, 22 ]. The leak test of the sample battery housing is carried out using two different measuring methods.
How much does a test battery pressure fluctuate?
Due to the mechanical load, the internal pressure in the housing of the test battery fluctuates by a few mbar. However, if the test specimen meets the requirements for leak-tightness (time point 1), the pressure fluctuates constantly around the test pressure of 100 mbar. At test time 2, no pressure drop can yet be seen in the black line.
