About PyBaMM

Star Fork

PyBaMM (Python Battery Mathematical Modelling) is an open-source battery simulation package written in Python. Our mission is to accelerate battery modelling research by providing open-source tools for multi-institutional, interdisciplinary collaboration.

Broadly, PyBaMM consists of

  1. A framework for writing and solving systems of differential equations
  2. A library of battery models and parameters, and
  3. Specialized tools for simulating battery-specific experiments and visualizing the results.

Together, these enable flexible model definitions and fast battery simulations, allowing users to explore the effect of different battery designs and modeling assumptions under a variety of operating scenarios.

If you like PyBaMM, please consider starring us on GitHub and spreading the word! You can also fork the repository to add your own models. For information about donations and how you can support, please see the Donate page.

Institutional Partners#


Ionworks is a company founded by members of the PyBaMM core development team to ensure PyBaMM’s long-term success. Ionworks provides support and custom feature development for PyBaMM, as well as software to make modeling easier and faster. For companies who want to leverage the power, flexibility, and openness of the Python ecosystem for their battery simulation needs, Ionworks is the go-to partner. Contact Ionworks to find out more.
