Fraunhofer is a key research partner in HAVEN, leading the development of novel cognitive power electronics while also contributing to diagnostics, modeling, integration, and sustainability. With its expertise in system design, impedance measurement, and edge platforms, Fraunhofer ensures that hybrid energy storage systems (HESS) are not only innovative but also reliable, scalable, and aligned with Europe’s sustainability goals.
What’s the main role of Fraunhofer in HAVEN?
Fraunhofer leads Work Package 3 on cognitive power electronics, designing high‑efficiency converters and developing edge platforms that host BMS and EMS functionalities. This includes embedding diagnostic intelligence into the system, such as impedance‑based methods to estimate State of Health (SoH) and State of Charge (SoC).
But its role goes beyond WP3. Fraunhofer also contributes to standardized measurement techniques in WP1, supports the evaluation of power electronics in WP2, and provides system‑level impedance models. In WP4, it develops battery state estimators and requirements for BMS integration, while in WP6 it helps validate HAVEN’s hybrid energy storage systems in real demonstrators—from EV charging to building power balancing and renewable‑based power plants. Finally, Fraunhofer contributes to WP7 by helping define eco‑design strategies to reduce the use of critical raw materials. In short, Fraunhofer connects advanced research with practical deployment across multiple layers of HAVEN.
What are the main challenges Fraunhofer may face in the project?
One of the main challenges for Fraunhofer is ensuring that its diagnostic and control methods work reliably across a wide variety of battery chemistries, configurations, and use cases. Hybrid systems are complex and creating universal solutions that remain accurate and efficient is demanding.
Another challenge lies in embedding these advanced functions into edge devices and converters that must operate in real time under industrial conditions. At the same time, Fraunhofer must validate its solutions in demonstrators, proving that they are scalable and aligned with sustainability goals such as reducing the use of critical raw materials. Balancing innovation, robustness, and eco‑design is not easy, but it is exactly where Fraunhofer’s expertise makes the difference in HAVEN.
