Fraunhofer-Institut für Integrierte Schaltungen IIS

For integrated energy supplies, issues relating to energy harvesting, battery management and power management are addressed. Furthermore, battery management systems are developed and optimized especially for complex battery and fuel cell systems, such as those used in hybrid and electric vehicles. These systems determine not only the exact state of charge (SOC) but also aging and remaining operating and service life. For the realization of vehicle-to-grid, connections for smart demand and billing of mobile consumers are developed from system architecture to prototypical implementation. Special embedded and highly integrated systems are the basis of many applications. Work focuses on the selection and adaptation of real-time operating systems as well as the design and implementation of configurable and extensible software. In addition, energy-efficient, adapted hardware is developed.

The Fraunhofer Institute for Integrated Circuits IIS conducts applied research and development on behalf of industrial companies and public institutions. It offers competence for intelligent information and communication technology for battery management, energy management, connection to smart grids with smart metering and smart demand, energy harvesting, embedded system software, energy-efficient circuit technology, localization and navigation.
