This paper is all about Design of Electric Vehicle. The growing development in the field of Electric vehicle in the need of the hour. In effort to save the environment and reduce our dependence on foreign oil, we planned of designing an Electric vehicle which can be used in conversion of any basic IC engine vehicle. Rapid climatic change, advances in renewable energy, rapid urbanization, battery chemistry and energy security are the result of developing an electric vehicle. In this paper we have consider most of the design aspect of electric vehicle and checked the results using a simulation software named modelica. This software enables us to have various drive trains, load dynamics and torque analysis. The Electric vehicles are environmental friendly, less expensive low maintenance, tend to be quiet, potential for tax credits and benefits to the utilities. IC engines automobiles emit harmful gases which are dangerous to health on other hand the electric vehicles emit hardly any harmful gases. NOMENCLATURE
