FIELD OF INVENTION
The present invention relates to energy generating apparatus for vehicle. Specifically, the present invention relates to an apparatus which generates electricity using Wind Energy. More particularly the present invention relates to diffuser augmented wind turbine installed in the vehicle. The said wind turbine is installed at front portion of the said vehicle.
BACKGROUND
Electrical vehicles, from completely electrical vehicles to internal combustion engines and combinations thereof, invariably require some form of electrical power. Generally this electrical power is supplied by rechargeable batteries that are carried on the vehicle. The problem is the batteries must be kept in a highly charged state. Further the said electrical cars are not capable of travelling long distance as the battery use to drain quickly.
A diffuser-augmented wind turbine (DAWT) is a wind turbine modified with a cone-shaped wind diffuser that is used to increase the efficiency of converting wind power to electrical power. The increased efficiency is possible due to the increased wind speeds the diffuser can provide. In traditional bare turbines, the rotor blades are vertically mounted at the top of a support tower or shaft. In a DAWT, the rotor blades are mounted within the diffuser, which is then placed on the top of the support tower. Additional modifications can be made to the diffuser in order to further increase efficiency.
The present invention provides a sustainable renewable energy generation for an electric vehicle using an diffuser with wind turbine, and regenerative braking system. This gives the running vehicle a consistent energy supply for increasing the range of the electrical vehicle.

DETAILED DESCRIPTION OF THE PRESENT INVENTION WITH REFERENCE TO ACCOMPANYING DRAWINGS
The present invention relates to an apparatus for energy generation in vehicles, wherein the said vehicle comprises of front portion 1, rear portion 2, DC generator 3, wind turbine 4 and diffuser 5. The said turbine comprises of turbine blades 6, shaft 7 attached between blades and vehicle chassis and pole 8 for fixing the turbine.
One embodiment of the present invention is diffuser 5 augmented wind turbine 4, wherein the said wind turbine 4 is mounted on the chassis of the vehicle, whereas the said turbine is fixed such that the front portion 1 of the diffuser faces front portion of-the vehicle and rear portion 2 of diffuser faces rear portion of the vehicle. The said diffuser is connected to chassis by means fasteners or welding. The said wind turbine having atleast three blades 6 made up of light weight material selected from aluminum, glass fiber, carbon fiber or plastic. The said blades 6 are aerofoil shape and are mounted on the wind turbine hub. The blades can be rotated on its axis or be fixed depending on complexity of the wind turbine design. The hub of the wind turbine is mounted on bearings and can freely rotate. The bearing assembly in turn connected to pole of the wind turbine. The pole 8 is attached to chassis of the vehicle using fasteners. The said turbine motor recovers the energy when vehicle is in motion.

Another embodiment of the present invention is multiple generator system that consists of atleast four small DC generators 3 which are fixed on the metal plate around its circumference, whereas the said metal plate 12 is fixed to the pole 8 of wind turbine near the wind turbine shaft • 7 end. A spur gear is attached to the wind turbine shaft 7 end. The energy from rotating wind turbine is transmitted to the generators using gears. A small sized gears 13 is fixed to the generators shaft to increase the speed of the generators in order to get sufficient charging voltage. An intermediate gears can also be used to still increase the speed of rotation of generators.
The Vehicle is propelled using brushless DC motor or three phase induction motor powered by lithium ion batteries, wherein atleast one battery is used for charging the vehicle even at motion. The energy for the present invention is further gained from three sources such as solar energy from panels, by means of regenerative braking system and diffuser augmented wind turbine.
In the present invention, separate DC generators are mounted at each wheel at the chassis arm 15. A DC generator is fixed at the chassis near wheels 10. The rotational motion of wheels 10 is transmitted to the generators using clutch 14 and gears 11. The clutch 14 is disconnected when vehicle is in motion. When brake pedal is pressed clutch is connected and the kinetic energy of the vehicle is transferred to the generators via clutch and gears. A gearing system is used to increase the rotational speed of the generators to get sufficient charging voltage. A disc brake or drum brake is also used in the vehicle and works tandem with regenerative braking system. If Brake pedal is pressed slowly then regenerative system takes place and slows down vehicle and takes long distance to stop but regains energy. If brake pedal is pressed harder then disc or drum brake comes into action to sudden stop of the vehicle. This system uses Permanent Magnet DC generators which is more efficient. The generator system is installed for both front and rear wheels.
The present invention comprises of buck boost converter system which allows smoothing out fluctuations due to variations in speed of the wind turbine. The buck boost converter system also allows maintaining constant voltage required for charging batteries by varying current according to availability of the energy. The said system is used in both Wind turbine DC generator and regenerating braking system.
In the preferred design of the present invention, a monitoring system is connected to monitor energy generated from solar, wind andregenerative braking system, further it also monitors the energy consumption for propelling , battery level and range of the vehicle.
In another preferred design of the present invention, wind energy is circulated by the turbine attached at the front portion of the vehicle and gets exits at back of the vehicle. The said diffuser allows air to get directional flow 9 and due to pressure difference between front and back end of the vehicle more air is sucked by the motor and thus increases efficiency of wind turbine. The multiple DC generator system allows energy to be captured from wind even at low speeds ie quick starting of wind turbine.

In the existing vehicle air flows over the body causing drag. But use of wind turbine allows air to flow easily and reducing drag to the vehicle. An experimental results show that there is increase in range upto 20 to 30%.
Advantages:
• fn the present invention the emission of carbon di oxide is controlled because of the use
of renewable energy.
© The present invention increases the normal range of the electric vehicle by 40 - 50%.
• Use of diffuser for wind turbine increases efficiency of wind turbine, thus recovering
more energy.
