From System Model to Operational Environment: Testing H2-Hybrid Drives for Mobile Machinery

To date, mobile machinery has mostly been powered by combustion engines and contributes significantly to environmental impact in Germany [1]. Increasing environmental awareness is reflected in legislation aimed at making European mobile machinery the cleanest in the world [2]. Hybrid H2 drives with battery and fuel cell promise zero well-to-wheel emissions and therefore offer the potential to meet future climate targets. However, integrating hybrid H2 FC drives into mobile machinery presents a notable challenge due to the complex mechatronic nature of these systems.

Electric Drive Design for Off-Highway Applications

Alternative Powertrain on Agricultural Tractors

The energy efficiency and reducing CO2 emissions is essential to promote sustainable agriculture. The main research areas are automation of tractors and implements, as well as the development and use of new technologies and alternative fuels such as methane, biofuels and synthetic fuels, hydrogen, and battery electric vehicles (BEV). It is becoming clear that advances in energy efficiency and propulsion technology are critical to meeting energy needs while minimizing environmental impact.
