The Hybrid Energy Storage Station (HEROES) project is now in month 20 and production of high-power cells (figure 1) for LiC modules and development of components for the system is ongoing. Cells are tested at the Institute of Energy Technology (IFE) in Norway (figure 2), Aalborg University (AAU) in Denmark, and at ElringKlinger (EK) in Germany.

IFE has developed an initial cell characterization analysis, and AAU initial parameters for the SoX algorithms (state-of-charge, state-of-health, and state-of-power algorithm) for the Battery Management System (BMS) for LiC. Lithium Balance (LBA) has completed the hard-ware design and finalized testing of the LiC BMS (figure 3). For the software, a mock-up integration of a Matlab/simulink autogenerated code has been executed and guidelines for integrating the SOX algorithms from AAU has been derived. LBA has also built a HIL setup and a battery test setup.

Beyonder is currently producing cells to ElringKlinger for development of LiC modules. ElringKlinger is currently developing LiC module design (figure 4) and will perform module testing in December-January 2022/2023. In April-May, they will produce LiC modules for the LiC rack that will be shipped to Siemens to be tested at Siemens's laboratory prior to be shipped for installation at a location defined by be.storaged.

At Siemens, development of the DC/DC converter is ongoing, basic design is performed. Be.storaged has identified two relevant locations for installation of the HEROES system. Clarification of permission from local authorities for installation has started.
Sustainable Innovation has developed the first version of exploitation strategy including an initial market assessment with relevant trends about widespread EV adoption and identified key exploitable results that HEROES partners are aiming to achieve throughout the project. An Intellectual Property Rights (IPR) strategy has also been outlined to showcase the different methods that partners can choose to protect their solutions.
The European Association for Storage of Energy (EASE) is responsible for communication and dissemination and has together with subcontractor developed a video illustrating the HEROES project and the benefit of the hybrid energy storage system. EASE has also published interviews of project partners and presented HEROES at several European conferences. HEROES was also presented at the Global Clean Energy Forum/Minister meeting in Pittsburgh in September by Beyonder and ElringKlinger.
Finally, ENSO is responsible for Life Cycle Analysis (LCA) and has developed questionnaire for input by Beyonder initially. ENSO is also working on defining the reference to compare the HEROES system to. This is a challenge as it is difficult to define what to compare the Hybrid Energy Storage Station developed in this project to.
