How can future electric drivetrains be optimally designed – from power electronics to tribology?
This question was at the heart of discussions during the 4th consortium meeting of the BMWK-funded joint research project Opt4E (Multi-criteria Synthesis and Optimization of Drivetrains for Electric Vehicles), held on October 7–8, 2025, and jointly hosted by IMKT and the Institute of Drive Systems and Power Electronics (IAL) at Leibniz University Hannover.
The two-day event focused on sharing the latest project progress and coordinating the upcoming work packages. Discussions centered on new approaches for the holistic optimization of electric drivetrains, in which aspects such as efficiency, NVH behavior, thermal management, manufacturing tolerances, and tribological losses are considered in an integrated manner. The project aims to develop methods and tools for fully integrated drivetrain design, covering all stages from concept development to system-level validation.
In addition to technical presentations, the meeting provided an excellent platform for in-depth discussions between academic and industrial partners. The hosts thank all participants for their valuable contributions and stimulating ideas for the next project phase.
