Markus Orner presents a methodology that enables the targeted design of the drivetrain and vehicle range of electric vehicles for specific application scenarios. The two-step method utilizes real usage data and is applicable to all areas with homogeneous usage. The author varies parameters such as charging infrastructure and battery costs. He illustrates this approach using the example of "Free-Floating Car-Sharing." This study thus aids in adapting electric drivetrains to new mobility forms such as car-sharing. Author Markus Orner earned his doctorate at the Institute of Internal Combustion Engines and Automotive Engineering at the University of Stuttgart and currently works in the field of design and testing of electric drivetrains.
