In the “Center for Energy Storage Technologies and Systems”, Fraunhofer ISE is focussing particularly on battery technology. We are working with novel materials and developing innovative production processes for battery cells and pursue new approaches for battery systems technology – from the cell, through the module, up to the complete battery pack including battery and thermal management. We optimize procedures to determine the state of charge and state of health as well as to predict the lifetime. In addition, we work on optimized charging and operation management strategies as well as battery system prototypes for widely varying application areas.
Our activities also include the modelling and simulation of batteries. We work with electrical, electrochemical and thermal models at the materials, on cell and system level. We carry out comprehensive testing and checking of batteries, including performance and aging investigations (calendaric, cyclic), thermal investigations, abuse tests and post mortem analyses. Furthermore, we have the competence to test different PV storage systems such as pico PV systems, Solar Home Systems, PV hybrid systems, grid-connected PV battery systems and storage system components (charge controllers, energy management systems, etc.).
We specialize in the comprehensive quality assurance of electrical and thermal storage systems. Our methods range from simulation-based system layout and optimization, through system tests in the laboratory and in the field up to system monitoring. In the area of thermal storage this includes both heat and cold storage.
