In the Circuit Network and the MSMD solution methods, the electric aspect of a battery is solved in Ansys Fluent. The following electro-chemical submodels are available in Ansys Fluent:
NTGK/DCIR Model
ECM Model
Newman's P2D Model
The NTGK/DCIR and ECM models are semi-empirical, while the Newman's P2D model is physics-based.
Details about these models are presented in the following sections:
