A synthesized diagnosis approach for the lithium-ion battery is proposed with fully understanding of the internal failure mechanism, which is suitable for dynamic conditions such as hybrid electric vehicles. In order to detect and distinguish different fault modes and bridge external electrical parameters with internal chemical mechanisms, a serial of abusive experiments, including overcharge, over-discharge, and low-temperature operation, which commonly occur during battery applications, are arranged. Fault symptoms in the form of electrical parameter variation are extracted with reference performance tests, which consist of hybrid pulse power characteristic test, federal urban driving schedule test, and incremental capacity analysis. The proposed diagnosis approach not only indicates the occurrence of fault but provides a detailed description of symptoms and physical meaning for internal mechanisms as well.
