Electric mobility is a key focus of research at the Institute of Electrical Energy Conversion (Institut für Elektrische Energiewandlung, IEW) at the University of Stuttgart. Research is split into two areas: electrical machines and inductive energy transfer. The scientists research the design of electric motors with extremely high torque densities and position-tolerant inductive charging stations. Their goal is the development of highly efficient components for the electric vehicles of the future. Due to their good controllability, their wide spectrum of use and their excellent efficiency, electric motors are perfectly suited for reducing primary energy consumption. Electric mobility requirements have shown that it is not sufficient to just adapt standard technologies to new fields of use. Drive systems optimised for use in electric vehicles, particularly wheel hub and direct drives, are the research focus of the IEW. It is essential to make a widespread charging infrastructure available first to be able to increase the number of electric vehicles in use. Inductive charging systems allow the wireless charging of electric vehicles and, at the same time, automate the charging operations so that, for example, cars can be charged on inner-city parking lots. This measure is definitely suited to increasing the range of electric vehicles. In this regard, IEW currently researches position-tolerant charging systems with an effi ciency factor of more than 90 per cent.
