VITO/EnergyVille is building interfaces between storage units and the system they form part of. These interfaces are the hardware and software components of battery management systems that safeguard efficient, flexible, secure and cost-effective integration of the storage units. These battery management systems are developed in a technology-independent manner using various topologies, so that the necessary flexibility can be provided depending on the application. VITO/EnergyVille also provides tools that are compatible with energy management systems and ensure that the right control strategy is chosen at any time depending on the ultimate objective and the exact status of the storage unit.
