A methodology to derive a computational efficient electro-thermal battery pack model is showed. It is taken the accuracy of 3D modeling from finite element method with an automatic technique of model order reduction. Approximation errors are under 2 % for a solution speed-up of three orders of magnitude for the thermal part. The electrical battery model is implemented and the electro-thermal coupling is done at the system level. This idea is demonstrated with a 10 cells battery pack.
