description

With the increasing number of sold electric vehicles, the diagnosis of lithium ion traction batteries will become an important topic. For the development of diagnostic concepts, it is of high importance to have a good overview and knowledge of the internal aging mechanisms which happen inside a single cell. This paper presents a review of existing literature on this topic and summarizes the known aging mechanisms using the FMEA method (Failure Mode and Effects Analysis) in order to categorize them and establish the relationship between failure effects and causes. Based on the summarized information, new diagnostic concepts can be developed.
