Brill Power has developed a lithium-ion battery pack which can combine cells from different chemistries and allows the replacement of individual cells within it.
(1) Together with Delta Motorsport, Aston Martin Lagonda and Imperial College London, as part of an InnovateUK project, Brill Power is designing, building and testing a hybrid battery system for high-performance vehicles. The Brill Power BMS enables the combination of high energy-density and high power-density devices in a single energy storage system, without a separate DC/DC converter. Another innovation developed as part of this project will be a software toolkit for optimal hybrid energy storage system design and simulation. (2) Brill Power's Pozibot project aims to develop a novel, dynamic warranty insurance product for batteries which, with the help of AI, goes beyond traditional risk calculation and forecasting and enables the insurance provider to conduct prescriptive analytics based on real-time battery health and usage data. Brill Power's contribution to the project includes a BMS solution for both stationary energy storage and electric vehicles, which communicates the low-level battery data necessary for such a dynamic warranty insurance approach. (3) In 2021, Brill Power launched their new BrillMS B62 battery management system which can increased battery pack lifetime up to 60% and improve reliability and storage capacity by up to 129%. The technology has been independently accredited by DNV GL.

Brill Power is conducting a feasibility study for developing its novel Battery Management System (BMS) technology for application in a 49.9MW grid-scale solar plus Energy Storage System (ESS) deployed by Narec Distributed Energy (Narec DE). Solar plus storage combines clean, renewable, but variable solar energy generation with a means to store that energy...
1 Oct 2020 to 30 Apr 2021
Brill Power and AMTE Power have identified a market opportunity for a modular, long-life battery system to electrify commercial vehicles with internal combustion engines, particularly medium and heavy goods vehicles. Commercial vehicles typically have high utilisation rates, which can cause lithium-ion batteries to lose more than 20% of their driving rang...

"The Hybrid Battery Optimisation (HBO) project will develop a novel type of high-performance hybrid energy storage system (HESS) with higher power and energy storage capability per weight than existing alternatives. Existing energy storage systems for hybrid electric vehicles (HEV) are typically based on a single type of electrochemical energy storage dev...

"The growth in the electrification of transport, including electric vehicles (EVs), has been driven by lithium-ion batteries. However, to make the next-generation of vehicles cheaper and more efficient, we need to be able to monitor, diagnose and respond to batteries in real-time. This project aims to combine new types of sensors to feed data into a batte...

"This project presents a unique opportunity for a young British start-up, Brill Power, to prove the business case for its pioneering battery management control system technology, through partnering with E-Car, the UK's leading electric vehicle (EV) sharing club. Currently EV batteries degrade at an unnecessarily quick rate (which will be worsened by the i...
1 Jan 2018 to 30 Sep 2018
This project will make a critical step towards a clean energy future by improving battery intelligence. Brill Power's innovative technology will not only mean that battery packs will last 60% longer, they will perform better over their lifetime, and reduce the cost to make batteries since fewer cells are required for a given battery performance. The appli...
