Brill Power was invited to present a poster about how battery pack capacities are determined by cell-to-cell variation and deterministic pack effects

Adrien Bizeray, Chief Data Scientist and co-founder, Jorn Reniers, Principal Engineer in Battery Modelling, and Martin Rogall, Senior Battery Modeller attended the Oxford Battery Modelling Symposium (OBMS) at the Mathematical Institute in Oxford to present a poster about how battery pack capacities are determined by cell-to-cell variation and deterministic pack effects.

In the publication, the team explored the impact of “static offsets” such as thermal gradients or inhomogeneous current on cell-to-cell variations in batteries. By fitting degradation models for cell degradation and cell-to-cell variation to the cell degradation data sets, the team was then able to simulate many pack designs with these degradation models.

The Oxford Battery Modelling Symposium (OBMS) is a unique event for the battery community bringing together mathematicians, chemists, physicists and engineers from academia and industry to discuss the latest modelling research and applications.

The event invites a small number of outstanding speakers spanning a range of topics from atomistic to continuum modelling, controls and beyond, giving broad and inspiring presentations and open discussions. The first event in 2019 was attended by 170 people with leading experts including John Newman speaking.

Adrien Bizeray commented: “We were delighted to be back in-person at the OBMS. It’s always such a great opportunity to meet with peers in the battery world. Collaboration is key to research and the event is a unique gathering of academic and industry minds who are moving the needle further in battery technology and development.”
