Overview of the research project EEBatt

The Research Project EEBatt “Distributed stationary battery storage systems for the efficient use of renewable energies and support of grid stability” is a multidisciplinary project run by the TUM’s Munich School of Engineering (MSE).

Combining the strength of 13 chairs and departments of the Technische Universität München, the industry partner VARTA Storage GmbH and the Bavarian Center for Applied Energy Research (ZAE Bayern), a multidisciplinary team of researchers works together on a wide range of issues concerning stationary storage of electrical energy. Driven by the actual evolution in the energy market, the main goal of the project is to investigate, develop and produce a decentralized energy storage device, which ensures that locally generated electrical power can be consumed locally. Based on the actual and expected results for lithium-ion technologies, EEBatt uses Lithium Iron Phosphate (LFP) and Lithium Titanate Oxide (LTO) chemistry for the setup. Together with the KWH Netz GmbH, a regional power supplier company in Haag/Upper Bavaria, the obtained results of the research project will be evaluated and implemented. 

The energy turnaround implicates not only a change in the technologies used for energy production, it also means a structural change towards a large number of decentralized time-dependent production facilities. The resulting fluctuations in the power production and imbalanced charging of the power grid make the use of storage technologies essential. The Bavarian Ministry of Economic Affairs and Media, Media and Technology initiated and finances the EEBatt research project to identify and explore possible storage solutions. 

The research project EEBatt pursues in the period from 01/01/2013 to 31/12/2016  the following objectives: 

  1. Development of an innovative decentralized stationary energy storage system
  2. Increase and secure the system security
  3. Optimization and advancement of the „Battery Management Systems“
  4. Increase battery lifetime and cycle stability
  5. Cost optimization, modular and scalable product design
  6. Reduction of the production costs
  7. Increase the overall efficiency 
  8. Development of an optimally adapted energy management system
  9. Cost-effective and intelligent integration

Field test Energy Neighbor

One result of the research project EEBatt is the stationary battery storage system ENERGY NEIGHBOR , which is going to be tested in Moosham (corporation Kirchdorf/Oberbayern). ENERGY NEIGHBOR  as a community energy storage system has a storage capacity of 200 kWh, which allows to consume local generated energy locally. Therefore ENERGY NEIGHBOR helps to integrate electricity produced from renewable energy sources better and to relieve the grid. This is a contribution to a sustainable and decentralized energy system.
