BattMo.jlFast open-source battery simulation

1D, 2D and 3D open-source P2D/PXD Lithium-Ion battery simulation

Accurate and open

Validated on standard benchmarks. Automatic differentiation and Julia syntax means that the code is easy to read and edit. Based on proven computational core for other multiphysics domains.

⚡

Fast and flexible

Written in Julia, simulate with scripting syntax without sacrificing performance. Extensible with new features.

BattMo Web App

A BattMo web application is available to run the simulation online without any further installation steps.

1D, 2D and 3D

One code handles both 1D models and complex 3D grids, with support for high-performance linear solvers for bigger models.

The Battery Modelling Toolbox (BattMo) is a resource for continuum modelling of electrochemical devices in MATLAB. The code features a pseudo X-dimensional (PXD) framework for the Doyle-Fuller-Newman model of lithium-ion battery cells. The code implements a subset of features from the MATLAB version of BattMo with improved numerical performance. BattMo.jl is based on Jutul.jl and uses finite-volume discretizations and automatic differentiation to simulate models in 1D, 2D and 3D.

The current implementation has many options for setting up simulation cases:

Set up 1D, 2D and 3D grids using scripting syntax
Templates for different types of battery chemistry parameters in JSON format
Support for a variety of open formats
Read in input data prepared in the MATLAB version of BattMo (coin-cell, jellyroll, pouch)
Make use of common BattMo JSON format to run cases
