Electric vehicle drive trains: From the specification sheet to the drive-train concept

Within the last years, the research for electric vehicles has significantly increased. Thereby the development of the drive train can be considered as a main challenge. The developers have to face the difficulty of identifying suitable drive trains out of many variants. This paper will show up a procedure to identify and evaluate appropriate drive train configurations for an underlying drive train concept. As the electric motor is one of the main components, with high influence on the overall efficiency, particular attention will be paid to it.
