Haid-Power: Development and testing center for batteries and energy storage systems

The first results and successes in the Haid-Power project have been achieved. The results include the successful specification, design and the procurement of the majority of the equipment for the planned test facilities. Furthermore, the energy requirements of the new laboratories in Haidhaus for the first stage of expansion have been determined and an analysis of the existing power supply has been carried out. Further works include the design and simulation-based validation of the expected power requirements for the planned further expansion of the new site. Based on these results, a call for tenders for a hybrid battery storage system was issued. In parallel with the tender for the battery storage, the load management system was successfully developed. Once the hybrid storage system will be delivered, it can be validated in the real system.

The integration of the hybrid battery storage system with a capacity and output of 840 kWh and 600 kW is a key element of the innovative power supply infrastructure and is progressing rapidly. With the commissioning planned in Q3 2022, the energy storage system is expected to be put in operation together with the existing rooftop photovoltaic system and the developed comprehensive load management system that will measure and control non-critical building infrastructure devices.

Thanks to the funding provided for the Haid-Power project by the federal and state ministries, the participating Fraunhofer Institutes ISE and EMI could expand their existing portfolios regarding the electrical, mechanical, and thermal testing of battery cells and systems, which is essential for consistent quality assurance of battery systems as central elements of the automotive industry of the future.
