The most ubiquitous cell-level modelling framework for LiBs is the Doyle–Fuller–Newman (DFN) model, called ''Dualfoil'' by its authors, but typically named ''the Newman model'' in the wider literature, or sometimes the ''pseudo-two-dimensional'' (P2D) model, owing to its consideration of physics on both macroscopic and microscopic scales.

In this work, a Julia-based framework (Jubat) has been developed for Newman's battery model. This framework benefits from the high execution efficiency of Julia language, so the mean computational time is lower than its counterpart PyBaMM written in Python. Governing equations are solved by the finite element method, and good accuracy is obtained.
The modelling of any battery pack will cover the electrical-thermal performance attributes of the cells. This mathematical modelling is likely to initially be a simple spreadsheet based model, then over time as the data and requirements mature so will the model.
In the present work, formal volume averaging of reformulated generalized Poisson–Nernst–Planck (PNP) equations in the form of concentration and electrochemical potential, or in the form of equivalent circuit on a representative porous microstructure, lead to “upscaled” equations similar to those in Newman's model.
These equations are similar to those established in Newman's model but they are not identical. First, electrochemical potentials of charge carriers are used throughout of the work instead of the physically less intuitive electrical potentials in Newman's model.
