Theoretical And Experimental Research Of The Propulsion System For An Electric Vehicle

This work proposes a theoretical study, modelling, experimental implementation and testing of an electric propulsion system, a system used in an electric vehicle. The main objective of the paper is to determine the existing problems within such a system and to propose some solutions, which will increase the efficiency of the entire system, a reduction in dimensions and costs. All these lead to the development of a compact, low-cost system that would encourage users to purchase such a vehicle.
The main objective was divided into three other objectives:

• making an electric machine control system
• creating an energy storage system
• connect the two subsystems, to build a complete electric propulsion system.
  The electric motor and the energy storage system are the main elements of an electric propulsion system. The most efficient implementation of these two elements leads to the efficient implementation of the entire system.

Personal Contributions:

Each element of the propulsion system was studied, analysed, and then implementations were carried out at the simulation level, but also practical implementations of the elements. The operation of the electric machine and its control was the first topic covered. The induction machine and the permanent magnet synchronous machine were studied, respectively, the methods to implement Field-Oriented control for each type of motor. The second topic was the energy storage system, more specifically the battery pack and its management system.
