Under-vehicle wind turbine system

In this paper we have proposed to introduce wind turbines on an EV, connected with a suitable generator to generate electricity utilizing the wind flow/power it experiences during the vehicle movement. Efficient design and implementation of wind turbines are crucial on the vehicles to obtain maximum energy output.

P. W. Ripley designed a system for harnessing wind energy to charge the battery of an electric motor vehicle. His invented system is capable of charging the vehicle's battery while it is parked or in motion. A roof-mounted, internal wind turbine is used to harness wind power, while the vehicle is in motion.

Abstract: Wine turbine applications such as battery charging for auxiliary power for boats or to power traffic warning signs. Wind turbines are becoming an increasingly important source. A wind turbine is a device that converts kinetic energy from the wind into electrical power.

In order to investigate energy-saving efficiency, a wind turbine of 400w was mounted to the front bumper of vehicle. In the experiment, there are two choices of charge types for vehicle. An electromagnetic clutch was designed for cutting charge system by wind turbine with a button in the car. Fuel consumption can be reduced using wind turbine.

While wine turbine system will self-stop when wind speed is too high at car speed more than 120 kilometers for safety. The road experiment results revealed that proposed vehicle wind turbine system saved about 15% fuel consumption when car speed is higher than 80 kilometers.

For example, in the year 2008, a team of students from the University of Stuttgart in Germany created Ventomobile, the first vehicle run solely by a two-meter twin blade wind turbine .
