Internal combustion engines are still most commonly used for driving mobile machinery. Electric drive units win because of their high efficiency, their possible recuperation and operation with renewable energies is becoming increasingly important. From a customer perspective, however, affects the limitation of labor input by the portable energy supply.
By including a second power source, however, the possible energy expenditure on a mobile machine can be increased significantly. At the Chair of Mobile Machines at the Karlsruhe Institute of Technology, the model-based development of electric hybrid drive systems and their operational strategies for mobile machinery is explored using extended XiL methods therefor.
