Battery System Technology

In the topic of Battery System Technology, our fields of work include:

Development of battery systems

Battery Interconnections

Battery Management Systems (BMS) and State Estimation

PV Home Storage and Commercial Storage

Modeling and Optimization of Batteries

For 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.

Die »Thermal Comfort for Electric Vehicles – Longer driving range for electric vehicles through optimized battery management

Blog post by Maximilian Bruch

Maximilian BruchWhat 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.

In our Center for Energy Storage Technologies and Systems we offer facilities for testing and characerization of battery systems:

  • Battery Testing
    • Tests and Characterization 
      In our laboratory facilities covering an area of 400 m², we test battery and systems based on, e.g., Li-ion, lead-acid, NiMH battery cells as well as high temperature batteries and double layer capacitors. Our laboratory equipment includes battery test systems, impedance spectrometers, calorimeters, etc. We use these systems to perform tests in the climate chamber or in a water bath based on accredited standards or customized to our client’s needs.
    • Aging Investigations
      To investigate aging and perform lifetime analyses of batteries and battery systems, we offer long-time tests carried out over several months and more. These tests contain both an investigation of the cyclic lifetime as well as calendar aging. For this purpose, we have about 180 test circuits for the button cell up to large storage systems.
