Failure mode and effects analysis of LFP battery module

Abstract

The analysis of the charge/discharge curve helps judge the quality of cells and figure out some strange behaviors of the battery module. Especially, many unusual behaviors won’t exhibit on the appearance. It’s important to establish the charge/discharge profile database for effective manufacturing and troubleshooting. In this talk, the basic charge/discharge method of Li-ion battery, simple equivalent circuit model of battery, general charge/discharge curve of LFP battery will be introduced. Then a case-by-case failure mode and effects analysis will be presented. Up to ten cases are discussed in the slides. Dr. Hsien-Ching Chung was invited by Dr. Jim Lee (the chairman of Taiwan Battery Association) to give a talk about "Failure mode and effects analysis of LFP battery module" in the conference, "2018 Taiwan-Japan exchange conference on battery materials and battery manufacturing technologies." The conference was held in Center for Space and Remote Sensing Research, National Central University, Taoyuan, Taiwan on Dec. 18, 2018. There were about 20 keynote speakers and 150 participants. It's a good opportunity to realize new technologies in the battery industry and the future of the energy industry.
