Abstract: Electrical vehicle (EV) is based on electric propulsion system. No internal combustion engine is used in it. All the power is based on electric power as the energy source. The main advantage is the high efficiency in power conversion through its offer system of electric motor. The operation, performance and efficiency of motor-driven electric vehicles are much better than engine-driven vehicles. The main drawback of Electric Vehicle is that it lacks the capability to run the vehicle for a long time due to insufficient energy storage in batteries. The energy storage capacity of the battery used in an electric vehicle is very low compared to conventional fuels used in modern automobiles. At the same time, electric vehicles are very environment friendly. Still, electric vehicles are falling behind in the automobile industries due to the problem of storage of energy. This paper proposes the concept of using dual battery system which is charged using wind energy when the vehicle is in motion or propelling. Charging the battery using wind energy may be done by using the energy of wind which is caused by the relative motion between the vehicle and the wind surrounding it. Wind turbines can be housed on the body structure of the vehicle to generate electricity in such a way that it must not create any additional drag force (rather than the existing drag force due to frontal area and skin friction) upon the vehicle. An aerodynamic analysis of the structure of the vehicle along with the flow pattern and wind turbine is presented in the paper. Optimum values of different design parameters and rated velocity of the vehicle are of prime concern. The idea behind the usage of two batteries (dual battery system) is to increase the reliability of the system and also to increase the run time. In future, we can charge the battery of electric vehicle by harvesting energy from other renewable energy sources like solar energy.
