Brill Power, an Oxford University spin-out company, announce the conclusion of its Series A round raising $10.5m today 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 will support team growth and new product development to expand presence in both static energy storage and the automotive sectors.




Brill Power’s technology is a key enabler for battery systems in applications including commercial & industrial buildings, on and off grid energy storage, residential homes an electric vehicles in a market estimated to be worth $400 billion by 20301. Brill’s solutions are consistent with their new investor interests in partnering with enablers of clean energy generation, including intermittent renewables, as part of the wider shift to clean infrastructure, businesses and technologies.


Brill Power’s plans following investment round are threefold. The company will double its team size across both engineering and commercial operations, while expanding its product range for both static energy storage and for the world’s largest battery market – electric vehicles – based on successful projects completed with Aston Martin, AMTE Power and Delta Cosworth. Finally, the funding will support the next phase in the development of the company’s data platform (BrillAnalytics) to help customers monitor and predict battery safety, health and performance data remotely.
