Using the car in motion relative wind power for charging the car batteries

This paper explores the possibility of using the power of the wind created by a car-in-motion for charging the car batteries. When a vehicle is moving even in a still atmosphere, a wind will act on a turbine mounted on the vehicle, this wind is called further relative wind. We study the possibility of using only the power of relative wind. The main disadvantage of electric and hybrid cars is the limited capacity of their storage batteries which impedes them from covering long distances. The obvious advantages of electric cars are canceled by the limited amount of energy stored in their batteries. Also, it is known that the conversion of an energy into another always comes with losses; therefore, a perpetuum mobile is not possible. We do not try to violate this principle, but we try to increase the efficiency of a wind turbine mounted on a car in motion. The wind turbine must be mounted on the vehicle chassis in a way to satisfy the aerodynamic and aesthetic criterions. So, the turbine system shall charge the car propulsion battery without creating supplementary friction. Results regarding the impact of the relative wind on the car conduct are analyzed using software named ANSYS and experimental tests and they are exposed in present paper. The base of this research is to demonstrate if the relative wind is sustainable to charge the battery in motion even for small improve.
