Abstract

A three-dimensional multiphysics-based thermal model of a battery pack is presented. The model is intended to demonstrate the cooling mechanism inside the battery pack. Heat transfer (HT) and computational fluid dynamics (CFD) physics are coupled for both time-dependent and steady-state simulation. Inside the battery cells in the pack a lumped value of heat generation (HG), that works as a volumetric heat source, is used. The measured HG stems from the cell level isothermal calorimeter experiment. The batteries inside the pack stay in the same initial thermal state in the simulation case. The pack is simulated to find the temperature gradient over the pack surfaces. Moreover, the temperature evolution results are simulated. It is demonstrated that the developed pack model can provide the thermal spatio-temporal behaviour with great detail. The result helps to understand the thermal behavior of the cells inside a battery pack.
