We design systems and develop diagnostics and control algorithms for electrochemical energy devices such as batteries and supercapacitors, in applications from electric cars to grid power systems.

The group is led by Associate Professor David Howey at the Department of Engineering Science in the University of Oxford.

Our aim is to improve performance and cost by predicting dynamics and lifetime, estimating temperatures and faults, and measuring how and why devices perform in the real world. This requires us to address fundamental issues in modelling, instrumentation and data processing.

Autumn update 2020 5 November 2020

We were delighted that Luis and Antti’s paper on battery parameter estimation won a best paper award at the recent ASME DSCC! Also, check out Antti’s other DSCC paper, on extracting battery SOH from live data, as well as work by Jie on thermal models given at ECS Prime (‘virtually’ Hawaii!). A very warm welcome to Dr Nicola Courtier and to Adam Lewis-Douglas, a new DPhil (doctoral) student in the group, both of them are affiliated with the Faraday Institution. Sad goodbyes to Dr Jorn Reniers (now at Brill Power) and Dr Pedro Ascencio (who has moved back to Chile to work in industry); they will be very sorely missed.

Building a sustainable community around battery modelling 2 July 2020

After a last minute change of plan due to the spread of Covid, we successfully ran OBMS this year as an online event, welcoming 150 attendees. This was so well received that a weekly webinar series has also begun, building on the momentum from OBMS. Read more about all of it in this ACS Article. We hope OBMS will be back in 2021.

Congrats to Jorn Reniers on passing his viva! 1 May 2020

Many congratulations to Jorn Reniers who earlier this year successfully defended his doctoral thesis on optimisation of batteries for grid storage using physically realistic degradation models. (Interested in this topic? Get in touch or check out this paper.)

STFC Futures Early Career Award 18 November 2019

Congratulations to Jie Lin, who has been awarded an early career award from the STFC Global Challenge Network in Batteries & Electrochemical Energy Devices. Jie will be collaborating with Imperial College to look at the thermal characterisation of Li-ion pouch cells.

Welcome, Luis! 1 October 2019

We are very pleased to welcome Dr Luis Couto to the group as a visitor. Luis joins us for a year having won a prestigious Wiener-Anspach Foundation Fellowship, and will work on battery fault diagnosis.
