Analysis of propulsion systems in electric vehicles

At the present time due to the environmental problems and to the problem of conservation of energy, the development of electrical vehicles (EVs) and hybrid vehicles (HEVs) have taken a great importance at world-wide level. Because of this problem the present paper describes the main parts of a EV propulsion system. The above mentioned is focusing mainly in the electrical parts, which are: the motor, the power converter, the electronic control and the batteries. This article was made with the intention of to analyze each one of the basic characteristics of EV with the goal of designing and construct an scaled EV.
