Fraunhofer Institute for Solar Energy Systems ISEFor applications with continuous demand, electric storage systems are required for all autonomous power supply systems. This applies to mobile devices (mobile phones, laptops), stationary technical devices (lights, signals), autonomous power systems for homes (Solar Home Systems, alpine huts), remote village and town power supply based on renewables and increasingly also for grid-connected applications (PV home storage). Battery systems play a key role in renewable energy systems, especially for PV and wind, due to their modularity and high energy efficiency. In addition, battery systems are also important for zero-emission and efficient mobility.
At Fraunhofer ISE, we focus on optimizing the battery system along the entire value chain from the cell through to the complete system. Depending on the application and user profile, the requirements on the battery system can be high. Batteries are required to operate safely. They may be exposed to extreme variations in temperature and are expected to have a long operating and cycle life. Further, batteries shall be fast charging and cost-effective.
With our comprehensive and long-term experience, innovative ideas and our state-of-the-art laboratory facilities, we have the competence to support our clients in developing competitive products. We can assist them in selecting the suitable technology from the cell level up to the system level, including the development of the complete system and its integration into the application.
What is the ideal operating temperature for electric cars? At what temperature do they perform best? The participants of the European research project JOSPEL are addressing just these questions by assessing the optimization potential of electric vehicles. The project aim is to increase the energy efficiency and range of electric vehicles by applying efficient and cost-effective climate control solutions especially developed for battery electric vehicles. Experts at Fraunhofer ISE are working with industry partners on optimizing battery operation, with the goal of increasing battery lifetime through improved thermal management.
