Integrated Electric Drives for Light Duty Electric Vehicles–Challenges & Opportunities

Date: 16/10/2025
Time: 9:00 am
Presenter: Shajjad Chowdhury and Vandana Rallabandi
Abstract: (Sponsored by PELS TC 3) Over the years, electric vehicle (EV) manufacturers have explored a wide range of innovative drive technologies to develop high-performance electric propulsion systems. Recognizing the challenges that remain, the U.S. Department of Energy (DOE), in collaboration with the U.S. automotive industry through the U.S. DRIVE partnership, has established ambitious technical targets for light-duty electric drives. Meeting these targets is critical not only for enhancing vehicle performance but also for accelerating the widespread adoption of electric vehicles in the mass market. In this seminar, the speakers will present recent research efforts at Oak Ridge National Laboratory (ORNL) focused on advancing electric drive systems for light-duty vehicles. The discussion will highlight progress toward meeting DOE targets, particularly in the development of high-power-density electric drives and will address the technical challenges and innovations required to achieve these goals.
