DNV has acted as technical consultant through the testing and verification of Brill Power’s new battery management system (BMS) technology. This testing confirms that Brill Power’s novel BMS concept brings advantages for a number of key battery characteristics like higher utilized pack capacity, that potentially result in lower lifetime cost.

DNV tested Brill Power’s new battery management system technology in its Battery Laboratory in Arnhem, the Netherlands, using innovative testing methods which verified safety functionalities and balancing capabilities. Control hardware-in-the-loop (CHIL) testing was used to validate the safety functionalities of the battery management system by simulating battery data within and outside of safe operational limits. The response of the battery management system to these simulated data were monitored and compared with their intended behaviour. DNV then conducted power hardware-in-the-loop (PHIL) testing on real battery cells to validate the functional safety and comparison of Brill Powers’ battery management system capabilities against other publicly available energy storage systems.

Hari Vamadevan, regional director UK & Ireland, senior vice president with DNV’s Energy Systems business area said: “We are excited to have qualified Brill Power’s new battery management system in our Battery Laboratory. Energy storage will play an increasingly important role in the future of power systems owing to a higher penetration of variable renewables generation. At DNV, we are keen to support the energy transition in a safe and robust way. Independent testing is a crucial element to verify any technology to ensure that it meets safety and performance requirements.”

Christoph Birkl, CEO and co-founder at Brill Power commented: “At Brill Power we develop innovative battery management system technology to enable batteries to reach their full potential for energy storage and electric vehicles. We approached DNV to test, appraise and ultimately verify our latest battery management system. Their exemplary work is an essential part of our wider mission to not only demonstrate our ability to increase the lifetime and sustainability of lithium-ion battery packs but to also reinforce our commitment to safety for this new technology within the power, renewables and electric vehicle industries.”
