Brill Power raises $10.5m in latest funding round

The company will use the funding to support team growth, new product development, and to expand its presence in static energy storage and the automotive sectors.

The round was led by new investors - Legal & General Capital and Barclays Sustainable Impact Capital Programme and supported by Brill’s existing investors including Oxford Science Enterprises, Oxford Investment Consultants and Oxford University. Shell Ventures and Climate KIC have also become shareholders.

Battery management systems (BMS) ensure batteries operate safely and effectively and are characterised as being active or passive.

According to Brill, active balancing battery management systems are costly and not a scalable proposition for mass application, whereas more affordable passive balancing solutions introduce operating inefficiencies and safety considerations into battery control.

Brill Power’s Active Loading method uses proprietary algorithms that determine the state of health and power capability of every parallel-connected cell block in the battery with novel control circuitry to regulate current. Stronger cell blocks are exposed to higher currents and weaker ones to lower currents to ensure maximum energy extraction from each individual cell during discharge cycles. Consequently, no single cell becomes the limiting factor in energy storage capacity, power capability or lifetime of the battery.
