Brill Power is an Oxford University spin-off that just launched a new battery management systems (BMS) that promises to revolutionise the performance of stationary energy-storage systems. The technology increases battery life by up to 60%, storage capacity by up to 129%, increasing systems uptime and driving down the lifetime operating costs for energy storage systems. Typically, energy-storage solutions require either passive balancing or more-costly active balancing topologies for efficient and safe operation. Brill Power’s new battery management system assesses the state of health and power capability of every parallel-connected cell block in the battery, then with its control circuitry regulates the electric current accordingly. Stronger cell blocks are exposed to higher currents and weaker ones to lower currents to ensure that each Joule of energy is extracted from each individual cell during every discharge cycle. As a result, no single cell limits the energy storage capacity, power capability or lifetime of the battery system. This way battery life is extended, but also reliability and uptime are improved, since faulty battery cells and modules can be bypassed and replaced whilst the entire system remains fully operational. Also, with regulated battery output voltage, the battery can be directly connected to other power sources or loads in the system, such as solar photovoltaic arrays or electric vehicle chargers for example, without using costly DC/DC converters or charge controllers. Brill Power also ensures system safety through cell-level protection that prevents currents exceeding safe limits, and any cell approaching hazardous conditions can be isolated. BrillMS B62 Premium is the first in a series of product launches from the spin-off intended to transform both the stationary energy storage market as well as the motive application of battery cells in electric vehicles. The BrillMS B62 Premium is particularly suitable for applications where the battery is a mission-critical component, such as uninterruptible power supplies (UPS), telecoms, medical and defence.
