Battery Design Module

Modeling batteries requires different levels of detail depending on the purpose of the simulations. The Battery Design Module is an add-on to the COMSOL Multiphysics® software that encompasses descriptions over a large range of scales, from the detailed structures in the battery's porous electrode to the battery pack scale including thermal management systems.

The descriptions involve physics phenomena such as transport of charged and neutral species, charge balances, chemical and electrochemical reactions, Joule heating and thermal effects due to electrochemical reactions, heat transfer, fluid flow, and other physical phenomena that are important for the understanding of a battery system.
