In the context of european H2020 research and development projects, our client and project partner is responsible of implementing a pilot site to prove the advantages of adding flexibility to the electric distribution grid. This pilot takes place in a secondary substation, which supplies 158 users.

A 210 kWh lithium battery was specially developed to provide top-class performance and interface with a custom built 100 kW Power Electronics. Both systems will help proving that a shared energy storage is a safe, reliable and emission-free alternative to gensets for critical loads.

The battery system consists of 22 Cell Modules connected in series, each with its self-developed BMS electronics, protections, cooling and digital interface. A Central Control Unit is also responsible of Power Electronics interface, network connection and data logging and monitoring of safety critical parameters.
