Development Trends in the Electric Mobility

The goal of the German Government is to bring one million electrical vehicles on German street until 2020. For this reason in Dortmund the center of excellence TIE-IN (Technology platform for interoperable electro mobility, Infrastructure and Grids) is founded. In this paper concepts for the development of electrical driver chains are described. One research approach for testing electrical vehicles is the use of a special power absorption roller, which is able to emulate up and downhill drives for testing the vehicle dynamics and the recuperation ability. Another concept for testing electrical drives is the use of a test stadion for the automotive drive chain. With this test bench the behavior of single components like the electric al machine or power electronics and their coaction are analyzed. Simultaneously a simulation library for electrical vehicles is developed. With this library it is possible to simulate single components, the electric al drive chain or the whole electric car in advance. The comparison with the test station allows defining high er grades of simulation models.
