Hyper-high-speed for electric vehicles to achieve maximum ranges

Period: 2018 – 2021

Cooperation: TU München (FZG), Leibniz Universität Hannover (IAL, IMKT), ATE, AVL, BMW, Fuchs, Lenze, Magna, Schaeffler

Speed4E is the follow-up project to the successfully completed research project Speed2E. As with in Speed2E, a purely electric drive train with two high-speed electric machines is to be designed and developed. The maximum speed should be raised from 30,000 to 50,000 rpm to further increase the power density. Another special feature is the multispeed sub transmission, which is realized by positive locking elements (dog clutches). For this purpose, a dedicated shift actuator and an innovative transmission control is developed. The integration of the drivetrain into a vehicle will enable the evaluation and optimization of shifting and driving comfort.
