In-depth analysis of the battery pack air tightness testing standards, an article to read the principles and methods
This paper describes in detail the importance, principles and methods of airtightness testing of new energy battery packs. The article describes the main application areas of battery packs and emphasizes the key role of airtightness testing in ensuring the safety of battery packs. The national testing standard GB 38031-2020 is introduced, and the three testing methods of pressure decay method, helium leakage detection method and water immersion method are explained in detail. Finally, the new energy testing equipment provided by JCGK was introduced, emphasizing the importance of ensuring the quality and safety of battery packs through strict testing.
