In this paper it will be discussed about the scope, feasibility and implementation of conversion of conventional passenger car into an electric car. Vehicles driven purely on electric power are the next step in the direction in which the industry for transport is already headed. There is a lot of reasons for using this type of drive for propulsion of a car: higher efficiency, reduced noise level, they are environmentally friendly, higher reliability and better driveability. Till recently, a major problem of these vehicles was a small driving range and the problem to efficiently store electricity, with the development of new technologies in the fields of chemistry, physics, mechanical engineering and electrical engineering, have enabled the development of better batteries with higher capacity, paving the way towards a more general application of the electric drive motor in passenger cars. Due to the scope of this topic, the limited time for preparation and the amount of funds needed for the actual implementation of the conversion, the emphasis of this work is solely on the theoretical side of the analysis how to convert conventional passenger cars with internal combustion engines to electric driven cars. This work is accomplished through several sections, starting with an overview of the development of electric cars through history, examination of specific components that make an electric car, through calculations examinated components for the conditions that were self presumed for the realization of this work, and finally with a conclusion that summarizes all
