AVL has developed 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with various geometries using Abaqus. In these models, the Li-ion battery system is simplified and modeled as heterogeneous solid medium consisting of a single or multiple equivalent battery layers with composite electrical and thermal conductivities for the equivalent anode, cathode and separator. Thermal behaviors of cylindrical, prismatic and pouch Li-ion battery cells and modules were analyzed under different electrical loads and cooling conditions. Simulation results were compared with available battery temperature measurements (covering cylindrical-cell and pouch-cell modules) and good agreements were observed. This indicates that the 3D electro-thermal model employed in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.
