Driving Innovation in EV Battery Design with Multiphysics Simulation Tools

Modeling and simulation (M&S) has become an important tool in the study of the design and operation of battery systems. The COMSOL software and its add-on Battery Design Module provide user-friendly yet powerful and versatile capabilities for describing batteries and electrochemical cells. The software also features multiphysics capabilities for coupling the electrochemistry within a battery with structural stress effects due to intercalation, heat generation, heat transfer, and computational fluid dynamics (CFD). Multiphysics models can be utilized to investigate thermal management and thermal runaway in individual cells as well as in battery modules and packs consisting of hundreds of cells.
