COMSOL is a global provider of simulation software for product design and research to technical enterprises, research labs and universities. Its COMSOL Multiphysics® product is an integrated software environment for creating physics-based models and simulation applications. A particular strength is its ability to account for coupled or multiphysics phenomena.
Modelling batteries require different levels of detail depending on the purpose of the simulations. COMSOL’s battery modelling capabilities allow engineers and researchers to optimise battery design in 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 the 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.
