054362 - HYBRID AND ELECTRIC VEHICLE
The course gives the students an overview of the hybrid/electric powertrain used in the automotive sector. The main objective is to analyze the hybrid/electric vehicle at system level, therefore analyzing how different solutions in the powertrain component sizing affects the whole vehicle performances. Scenarios and perspectives for the electrification will be discussed considering especially the European market before detailing the main important technical aspects: vehicle architecture, electrical motor/converter, on board storage system, energy management algorithms and charging infrastructures.
Risultati di apprendimento attesi
Lectures will provide the basis for basic knowledge to understand all the key aspect involved in the design of a hybrid / electric powertrain (Knowledge and understanding). Furthermore, in order to give the student an industrial picture of electrification, seminars given by engineers from automotive companies will be organized. In this way students will understand both the research and the industrial approach to the electric/hybrid vehicle.
Some practical exercises will be proposed in order to let the student to acquire the knowlodge to face some engineering problem as the sizing of hybrid powertrain, of battery or hybrid storage system. At last students will be asked to prepare a work project during the course in small group (3-4 person) in order to apply the acquired knowledge on a specific vehicle to be analyzed, proposing a hybridization/electrification solution. During the course the project development will be discussed with the lecturer/tutors. This project will be presented during the final exam.
The main topics of the course are listed in the following bullets.
Scenarios and perspectives for the electrification in road transport: market prenetration of hybrid and electric vehicles, requirements for mass production, forecasts especially considering the European market;
Hybrid and electric vehicles’ architectures: overview of the different mechanical layouts of hybrid and electric powertrains, influence on the powertrain performance and complexity, evaluation of the overall efficiency and the related pollutant emissions;
Electric motors and power converters: basic working principles and fundamental equations of the principal electric machines (Permanent Magnet brushless DC, PM brushless AC, axial flux synchronous motors, …) used in battery/hybrid electric vehicles, sizing and thermal issues, overview on power electronic technologies used for on board power converters (Mosfets, IGBTs, ...);
On board storage systems: different battery chemistries and technologies, overview of other on board storage systems, forecast of future battery performances, Battery Management System, hybrid storage systems, battery testing;
