Summary

Around the world the legislative requirements on battery safety and customer demands are currently strengthened due to the increasing market share of battery electric vehicles. In this context, the biggest safety challenge is avoiding thermal propagation, i.e. avoiding a “cascading wildfire” in the battery system caused by a thermal event of a single cell. China set standards in the regulation of thermal propagation (TP) requirements a few years ago, but battery requirements are currently being revised worldwide, particularly with regard to TP. Apart from the safety of battery systems, long battery lifetime is of high interest for customers. 

This article first provides an overview of the currently applicable and future expected regulatory requirements regarding TP. Secondly, statistical evaluations of the "TP performance" of current battery systems based on FEV`s project experience with a large number of TP tests are shown. A general overview on new chemistries (e.g NCMA, LFMP, Solid State, Natrium Ion) and their specifics is given.
