Electric Performance and Efficiency of Wind Turbines in Electric Vehicles

Abstract

Recently, mankind's need for more amount of energy has been increasing day by day, though there is a trend to reduce the usage of the traditional energy source to an energy carrier (or fuel) that results in emitting harmful gases to the environment that is separated in the air and water. Researchers have conducted researches to increase projects that will generate clean and renewable energy. Usage of renewable energy via mankind is in continuous progress such as solar energy, bioenergy, ocean energy and wind energy. Wind energy waste while the car moved was used to produce electric energy. The term "electric vehicle" refers to any vehicle using electric propulsion motors. The maximum speed of travel on public roads and city streets varies by country. Electric cars need to charge their batteries every 300 km or 400 km, we propose to add wind turbines to an electric car for using wind energy neglected during the movement of the vehicle to produce electricity. In this research, the usage of unused wind energy in vehicles was developed so that additional power for vehicles is made possible and that is via converting wind power into electric one. The wind turbine was assembled from a fan and transducer. Indoor test showed generation of different electric voltages when varying the ambient temperature and has inverse proportionality with the ambient temperature. The main experiment was carried out so that the wind turbine was installed above the car and connect it with a battery; values of voltages and currents in various speeds of the car were recorded. When two transducers and five fans were used with different specification, the consequence was a direct proportionality instead was recorded power, between voltages, currents and power car's speeds. A comparison between the five fans with two transducer showed that: the light weighted fan with big blade dimensions was the best one to generate voltages. Finally, These results offer a solution that we can avail from wind energy to supply batteries or operate the vehicle directly as long as vehicles move along the way.
