Procedure for Bubble Leak Integrity Testing: The objective of this study is to reduce the heat seal leak rejection in the lead-acid battery assembly process using Six Sigma's DMAIC (Define, Measure, Analyze, Improve and Control) methodology.
Additionally, we established a comprehensive thermal analysis capability that enables us to identify and measure exothermic and endothermic reactions within a lithium-ion battery cell. Testing to battery module and pack testing standards and local country marks. We test and certify battery modules and packs to diverse standards. “A select few are using tracer gas to test their battery packs,” explains Hagyard. “The type of leak test equipment necessary is also dependent upon the size of the battery pack, its flexible nature and the leak rate.” In-Process vs. End-of-Line Testing. Manufacturers use both in-process and end-of-line leak testing.
leak test for battery cells With HEV/EV technology comes new leak test requirements for the automotive industry: each single battery cell must be protected, reliably, against any penetration of humidity and air.
