Abstract

Environmental pollution problems are increased and utilization of renewable sources is important. Moreover, the fossil fuels make the environment weaken and this will encourage providing an alternate energy resources. Wind energy is one of the popular renewable energy resource and this paper deals with a novel charging mechanism utilizing this resource for automatically charging the battery packs of electric vehicles (EVs). In this study, the wind speed is determined for Chennai city in India for four different seasons. The hourly average wind speed for one day has been estimated by Weibull distribution and it is compared with three different methods for the hourly averaged wind data. The results show that the power density method outperforms and the Weibull distribution fit with the wind data. The energy and power density for each season are calculated and the performance of four different small scale turbines has been evaluated. Automatic recharging can reduce the requirement of fossil fuels to generate electricity, as a result CO2 related emissions are reduced tremendously and increase of the traveling distance is minimized. Hence it is not necessary to wait for recharging in various stations and the vehicle can move long distance after one full charge by this method. The simulation result shows that the performance of small scale turbine is satisfactory and the batteries are recharged without using recharging stations.
