Abstract
In this work a three dimensional impedance-based electric battery model is coupled with a thermal model. Both parts are verified by comparing measurement and simulation. Subsequently the model is used to simulate a locally limited internal short-circuit inside a cell and inside a battery pack. Based on the simulations, suggestions for improvements of passive safety are made.
