The course aims at providing the students with an in-depth knowledge of all-electric and hybrid electric vehicle propulsion systems, specifically focusing on the application of power electronics and electric drives to improve energy efficiency and fuel consumption, extend the driving range, and achieve adequate performance. At the end of the course, students will know the main components and architectures of both conventional and electric drivetrains and comprehend their operating principles, they will be able to chose between modern electric motor and power electronic converter technologies the most suited for electric propulsion systems applications. Furthermore, students will learn the general criteria for the design of an electric drivetrain and the implementation of the drive control strategy. They will also be able to analyse and critically evaluate its performance in relation to the traction application requirements.
