ABSTRACT
Generally wind energy systems can convert the kinetic energy to more useful forms of power.
Wind blades transform the energy in the wind into mechanical power, which can then be used to
generate electricity and it can be used to charge large batteries. But for initial stage we have tried
it in miniature level of charging a 12v lead acid battery since it is easily available to us. So This
paper deals with implementation of wind driven generator technology to produce electricity
in charging of mobile phone in two wheeler. We are generating electrical energy with help of
wind energy when the vehicle is running. The generated electrical energy will be stored in the
lead acid battery which can be used for charging purpose.

INTRODUCTION
With the population explosion, exploitation of natural resources is heading towards its peak.
Some projections indicate that the global energy demand will almost triple by 2050 and oil can
only supply the world for up to 150 years. Keeping these facts in mind, science has started
emphasising upon sustainable development and has come up with advanced methods of energy
conservation. We have developed different technologies for utilization of renewable resources of
energy and these technologies are also being implemented in almost all sectors. Whether it is
power generation by hydro projects or use of large scale solar panels, these technologies are
being used at an extensive scale.
WIND ENERGY
Wind energy is the kinetic energy associated with the movement of atmospheric air. It has been
used for hundreds of years for sailing and for irrigation. Wind energy systems convert this
kinetic energy to more useful forms of power. Wind blades transform the energy in the wind
into mechanical power, which can then be used directly for sailing etc. or further converting to
electric power to generate electricity. Small wind turbines called aero-generators can be used to
charge large batteries. Five nations – Germany, USA, Denmark, Spain and India – account for
80% of the world’s installed wind energy capacity. Wind energy continues to be the fastest
growing renewable energy source with worldwide wind power installed capacity reaching 14,000
MW.Realizing the growing importance of wind energy, manufacturers have steadily been
increasing the unit size of the wind electric generators since the late 1980s.
DC GENERATOR
An electrical Generator is a machine which converts mechanical energy (or power) into electrical
energy (or power).
Principle of DC GENERATOR:
It is based on the principle of production of dynamically (or motionally) induced e.m.f
(Electromotive Force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f. is
9
produced in it according to Faraday's Laws of Electromagnetic Induction. This e.m.f. causes a
current to flow if the conductor circuit is closed.
Hence, the basic essential parts of an electric generator are :
1)A magnetic field and
2)A conductor or conductors which can so move as to cut the flux.
Construction :
A single-turn rectangular copper coil abcd moving about its own axis in a magnetic field
provided by either permanent magnets or electromagnets. The two ends of the coil are joined to
two split-rings which are insulated from each other and from the central shaft. Two collecting
brushes (of carbon or copper) press against the slip rings.

ANALYSIS OF FAN (USING CATIA SOFTWARE)
WHY PLASTIC FAN?
There are some reasons to chosen the plastic fan. They are following,
Less weight
Can produce more rotations
Can produce high mechanical energy
Easily available.
The different views of the fan with the above dimensions are,
14
The properties of the fan used are shown below,
So due to the above properties, the fan can withstand for long time.

WORKING:
Since the required properties for the rotation has obtained in the above fan it is finalized and used
in our project.
Here in our project we used TVS XL HEAVY DUTY vehicle for testing.
1.The generator coupled with the fan is fixed in the front side of the vehicle (below the head
light)
2.Then it is connected with the battery (lead acid battery) and dc charger.
3.As the dc charger having the capacity to convert 6/12 v to 4v (required for charge the mobile
phone) it is used here.
4.So then the dc charger output is given as input to the mobile phone to charge it.
5.The charging will start when the vehicle reaches the speed of 30km/hr.
6.Before reaches the above speed it will produce some electric charge and stored in the battery.

2 - it is the place where battery is kept.

RESULTS AND DISCUSSIONS:
By the above method it produced the current required for charge the mobile phone.
If it reaches the maximum speed also it will produce charge up to its maximum.
since that vehicle used is 67cc we planned to use this method in some other
vehicles which having higher capacity than this.
The following results were obtained while checking with the 12v Dc Generator.

Battery Efficiency
Lead acid batteries typically have coulombic efficiencies of 85% and energy efficiencies in the
order of 70%.
Battery stand by time
Since Lead acid batteries having the above efficiencies it dissipates very negligible amount of
charge only if we don’t use it for some days .

TASKS OVERCOME:
First we checked how much voltage is generating for different speeds in the
vehicle.
While checking that with 12v dc generator it produced the minimum voltage
of 2.5v for 10km/hr and maximum voltage of 8.9v for 60 km/hr.
After then we fixed the setup in back of the vehicle (below the danger light)
there it is not efficient (i.e the air required for rotation of fan is very low)
So again we changed the location to front side of the vehicle.
In front side the above observations were obtained.
Then the fan with two blades are coupled with generator and tested
After then, for getting more number of rotations of fan we changed the fan
with three blades.
Its efficiency is more compared to the two blade fan since its self weight is
more.

Conclusions:
In this mini project electricity is produced from wind energy. By using this we can
charge the mobile in two wheeler while riding. In this project we made use of
generator coupled with the blades of fan in order to produce electricity. If the
vehicle is running at the speed up to the maximum of 60 km/hr it is producing
electric charge of (8-9)v. so it is an additional energy producing system for a two
wheeler. We can use the charge produced from this system for some other
purposes (head light, indicators, horn, etc.,). This method is very simple and
compact in size. Therefore it is appropriate for the vehicles which are less than 100
cc.

Future scope of this project:
In future, This project will be implement in the bikes which is more than
100cc by using the high voltage generators (120v, 230v, etc.,) and some
recent techniques.
In future, by this technique the power produced from that may be used to run
the electric bike is also possible.
In future the blades in the fan will be increased in numbers to get more
power will be tested.
