Objectives

The course of Electric Vehicles aims to provide students with knowledge of electric vehicles and electric mobility. It is important to acquire an awareness of the motivations, objectives and opportunities characterizing electric vehicles, electric mobility and the growing transition of the transport sector towards the electric carrier. Therefore, the electric and hybrid electric road vehicles are analysed, with the aim of acquiring the appropriate knowledge on the configurations and technologies used, their operation, and relative performances. Finally, the potential effects of the spread of hybrid electric and electric vehicles and the appropriate planning strategies are assessed, with particular attention to Vehicle-to-Grid technology.

More in detail, the educational objectives of the course can be expressed according to the following five descriptors:
- Knowledge and understanding: Knowledge and understanding of (1) the energy issues related to the transport sector and the relative opportunities offered by electric mobility, (2) the principles of vehicle dynamics and (3) the electric and hybrid electric vehicle structures, focusing on their configurations and their operation. Knowledge of (4) the characteristics of the charging systems and the basic principles of the planning of charging infrastructures.
- Applying knowledge and understanding: Ability to (1) analyse and model electric vehicles, (2) implement their models in Matlab / Simulink, (3) evaluate their performance and (4) accomplish a preliminary design of the propulsion system.
- Making judgements: Ability to correctly assess the presences of the various types of energy systems. Ability to accurately evaluate the performance of the different types of electric vehicles based on their technical characteristics.
- Communication skills: Ability to discuss, with specialist interlocutors, problems and solutions associated with the use and rational production of energy. Ability to discuss the issues and solutions concerning electric vehicles and electric mobility with specialists and non-specialists.
- Learning skills: Ability to continuous learning, through the correct interpretation of technical documents and scientific bibliography.

Prerequisites

To profitably attend the course, knowledge and competences in mathematical analysis, physics, electrical engineering and thermodynamics are fundamental. Basic knowledge of power electronic converters and electrical drives is useful. Basic Matlab-Simulink skills are strongly recommended.

Contents

The course of Electric Vehicles is divided into 30 hours of theoretical frontal lessons and 20 hours of exercises, for a total of 50 hours.

The course program is as follows:
- Introduction to electric vehicles: motivations, objectives, opportunities (2 hours theory + 1 hour tutorial)
- Principles of vehicle dynamics: longitudinal model, resistant forces; vehicle performance, propulsion system characteristics; operating mode; driving cycles, consumption estimation (6 hours theory + 4 hours exercises)
- Electric vehicles: configurations; main components, energy storage systems, power electronic converters, electrical machines, transmission systems; functioning (8 hours theory + 6 hours exercises)
- Hybrid electric vehicles: notes on thermal propulsion systems; configurations, architectures, management and control strategies (6 hours theory + 2 hours exercise)
- Regenerative braking: principles of braking and regeneration (4 hours theory + 2 hours exercise)
- Planning the electric mobility: charging systems, problems and opportunities, vehicle-to-grid (4 hours theory)
- Final exercise (5 hours exercise)

Teaching Methods

The Electric Vehicles course includes 30 hours of lectures, mainly delivered in person, appropriately integrated and with online lessons, in order to guarantee its fruition in an innovative and inclusive way. During the lectures, the student acquires knowledge on vehicle modelling, on the architecture of electric vehicles and hybrid electric vehicles, on management and control strategies of electric and hybrid electric vehicles, and on planning electric mobility. Lectures consist of explanations on the blackboard that are appropriately accompanied by suitable slide shows. Furthermore, the lectures are complemented by 20 hours of exercises that allow the student to develop the ability to apply the knowledge acquired during the lectures, to simulate the functioning of an electric vehicle and estimate its energy consumption. The exercises are carried out using the Matlab-Simulink software and will be supervised by the professor.

Verification of learning

The student's assessment includes an oral exam. The student is asked to discuss some topics covered during the course, both from a theoretical and practical point of view. Particularly, the oral exam consists of three questions: the first question regards the exercises, whereas the second and the third questions focus on the theoretical topics discussed during the classes.

The student has to demonstrate the acquisition of sufficient knowledge and understanding regarding the configurations and operation of electric and hybrid electric vehicles. The student is also required to have enough capacity to apply this knowledge; in particular, some of the questions will concern the general dimensioning of the propulsion system and simulation of the electric vehicles addressed during the course exercises.

A mark expressed in thirtieths gives the exam test score. To pass the exam and, therefore, report a grade of not less than 18/30, the student must demonstrate to have acquired sufficient knowledge and understanding of the main topics developed during the teaching. To achieve a score of 30/30 cum laude, the student must instead demonstrate to have acquired excellent knowledge and understanding of the topics covered during the course.
