8th Converence Hybrid and Energy-efficient Drives for Mobile Machines

Karlsruhe

23. February 2021

On February 23rd, the 8th conference"Hybrid and energy-efficient drives for mobile machines" took place, for the first time as a digital event due to the Covid-19 pandemic. Prof. Dr.-Ing. Marcus Geimer welcomed around 130 experts from industry and science to the online conference platform.

The conference was organized by the Mobile Machinery Division of the Karlsruhe Institute of Technology (KIT) and the German Engineering Federation (VDMA) in cooperation with the Scientific Association for Mobile Machinery.

While the focus in 2019 was on the integration of electric and hybrid drives, as well as their operation and energy storage, this conference presented and discussed various development methods in addition to innovative control and driving strategies.

The symposium opened with a presentation by the Forschungsvereinigung Antriebstechnik e.V. on the effects of the fuel cell strategy on mechanical and plant engineering, followed by a presentation on the networking of drive systems by DEUTZ AG.

In the following session, which focused on smart machine control and driving strategies, the companies ZF Friedrichshafen AG, RWTH Aachen, Danfoss Power Solutions GmbH & Co. OHG and TU Braunschweig presented new driving strategies, hydraulic multi-pressure systems, electrified wheel loaders and flushing and feeding systems.

After the lunch break, Greening GmbH & Co KG, Ravensburg-Weingarten University of Applied Sciences, stoba e-Systems GmbH and RWTH Aachen University presented the current status of implementing and using electric drives in terms of battery systems, cooling, integrated drives and metrological testing.

The final session dealt with the topic of development methodologies. TU Dresden, FLUIDON Gesellschaft für Fluidtechnik mbH and Aalen University reported on sensor-controlled tool systems, digital twins for Industry 4.0 and application-adapted driving profiles.

Prof. Geimer concluded the 8th symposium with his closing remarks on the positive outcome of the current format and the outlook for the next symposium.

The 13 papers presented showed the great importance and the expected change in the field of hybrid and energy-efficient drives for mobile machinery in industry and science. New impetus can be expected that will bring both a reduction in emissions and added value in the form of increased efficiency and improved cost-effectiveness. We can look forward to the announced continuation in 2023.

During the breaks, participants were able to find out about current projects at the poster session accompanying the conference or discuss further questions with the speakers in the Speakers' Corner. 13 participants took the opportunity to present their posters in the poster session.

The conference proceedings produced to accompany the conference can be obtained from KIT Scientific Publishing (ISBN 9783731510710). The presentation documents released by the speakers are available for download on the homepage (Mobima) of the Mobile Machinery Institute, KIT.
