Brill Power brings together world-class leaders in Battery Intelligence.


Created in Oxford
Our story
Established in 2016, Brill Power is a founder-run start-up with roots in the Engineering Department at the University of Oxford. Our first product for the stationary storage market launched in 2021 and we are expanding into new markets such as electric vehicles.
Brill Power successfully achieved a Series A round raising of $10.5m in 2022 to support their mission to make batteries smarter, cleaner, safer and longer-lasting as a critical element of the shift to zero emissions energy. The funding supports team growth and new product development to expand presence in both static energy storage and the automotive sectors.
The round was led by two new blue-chip investors – Legal & General Capital and Barclays Sustainable Impact Capital Programme and supported by all of Brill’s existing investors including Oxford Science Enterprises, Oxford Investment Consultants and Oxford University. Shell Ventures and Climate KIC have also become shareholders.
