Commercial battery energy storage systems – ranging from few to hundreds kW - provide peak shaving, load shifting, emergency backup and frequency regulation to a grid helping improve power quality and are often integrated with renewable energy sources – including wind and solar - to smooth-out their varying and intermittent outputs. They usually comprise bi-directional dc-ac inverters interfacing to the grid and bi-directional dc-dc converters that control energy flow to and from each battery rack independently, ensuring they are kept in their optimal operating conditions and helping minimize battery imbalance to improve efficiency, capacity, lifetime and maintenance of the system.

We can provide a range of power discretes including silicon-carbide (SiC) and silicon power MOSFETs – including ACEpack power modules - and diodes and isolated gate drivers as well as high-performance STM32 microcontrollers and energy metering ICs to help develop high-efficiency commercial battery storage systems.
