Abstract: Electric drive transmissions for passenger cars and light commercial vehicles

The presentation starts with an analysis of the most important global markets, e.g. with regard to the share between conventional powertrain, hybrid drivetrain and battery electric drivetrain. The most important markets develop differently. The simulation results show the advantages and disadvantages of the different transmission solutions presented, e.g. single speed vs. multi speed of the battery electric powertrain. Multi-speed, powershifting transmissions for battery electric vehicles are a rather new technology. Are multi-speed transmissions for battery electric vehicles really useful? This question is answered for different vehicle segments. Both technical solutions, countershaft vs. planetary gear design, will also be presented.
