INTRODUCTION
Electric vehicles have become increasingly popular in recent years as consumers become more
environmentally conscious and look for ways to reduce their carbon footprint. However, one
of the biggest challenges facing electric vehicles is the issue of charging. While electric vehicles
can be charged using external power sources such as charging stations or home charging units,
the need for these external sources limits the range and flexibility of electric vehicles. However,
researchers and engineers have been exploring new and innovative ways to address this
challenge, including the development of a self-charging system for electric vehicles using wind
energy turbine mounted on the vehicle itself.
The idea of using wind energy to power electric vehicles is not new. Wind turbines have been
used for decades to generate electricity, and electric vehicles have been around for over a
century. However, mounting a wind turbine directly on the vehicle itself is a relatively new
concept that has the potential to revolutionize the way we think about electric vehicle charging.
The basic idea behind a self-charging system for electric vehicles using wind energy turbine
mounted on the vehicle itself is that the wind turbine would generate electricity while the
vehicle is in motion, and this electricity would be used to charge the battery of the electric
vehicle. This means that the vehicle could be charged while it is being driven, without the need
for an external power source or the need to stop and plug in to charge.
There are several potential benefits to a self-charging system for electric vehicles using wind
energy turbine mounted on the vehicle itself. One of the most significant benefits is the
potential to increase the range and flexibility of electric vehicles. Currently, one of the main
limitations of electric vehicles is their range, as they can only travel a certain distance before
needing to be recharged. With a self-charging system, electric vehicles could potentially travel
indefinitely, as long as there is sufficient wind to generate electricity.
Another potential benefit of a self-charging system for electric vehicles using wind energy
turbine mounted on the vehicle itself is that it could help to reduce the cost of charging. With a
self-charging system, electric vehicle owners would not need to pay for external charging
sources, as the wind turbine would generate electricity for free. This could make electric
vehicles more affordable and accessible for consumers.
Despite these potential benefits, there are also some challenges associated with a self-charging
system for electric vehicles using wind energy turbine mounted on the vehicle itself. One of
1
the main challenges is the need to design and engineer a wind turbine that is efficient, durable,
and safe to mount on a vehicle. Wind turbines are typically large and heavy, and mounting one
on a vehicle would require significant engineering expertise.
Additionally, there may be concerns around the safety and stability of a wind turbine mounted
on a moving vehicle. Wind turbines are typically designed to be mounted on stationary
structures such as wind towers, and the vibration and movement of a vehicle could potentially
compromise the stability and efficiency of the turbine.
Despite these challenges, there has been significant progress in the development of a self-
charging system for electric vehicles using wind energy turbine mounted on the vehicle itself.
Researchers and engineers are exploring ways to improve the efficiency and reliability of these
systems, as well as ensuring their safety and durability.

ADVANTAGES
Here are some potential advantages of a self-charging system for electric vehicles using wind
energy turbine mounted on the vehicle itself:
1. Increased range and flexibility: A self-charging system can potentially extend the range of
an electric vehicle by generating power while the vehicle is in motion, as long as there is
sufficient wind to generate electricity. This could also provide greater flexibility in terms
of where and when an electric vehicle can be driven, as there would be less need to plan
trips around available charging stations.
2. Reduced charging costs: With a self-charging system, electric vehicle owners can generate
their own electricity for free, reducing or even eliminating the cost of charging their
vehicles at external charging stations.
3. Environmental benefits: Wind energy is a clean and renewable energy source, so a self-
charging system using wind energy can significantly reduce carbon emissions and
minimize environmental impact.
4. Energy independence: By generating their own electricity, electric vehicle owners can
become less reliant on external sources of energy, providing greater energy independence
and potentially reducing vulnerability to power outages.
7. Improved battery life: With a self-charging system, the electric vehicle's battery may
experience less strain, as the wind turbine can generate electricity to charge the battery
while the vehicle is in motion. This could extend the life of the battery and reduce the need
for battery replacement.

8. Reduced carbon footprint: By using wind energy to power electric vehicles, a self-charging
system can significantly reduce carbon emissions and contribute to mitigating climate
change.
9. Increased resilience: A self-charging system can potentially increase the resilience of the
electric grid by reducing the demand for external power sources during peak usage times.
10. Sustainable transportation: A self-charging system using wind energy can contribute to
making transportation more sustainable and reducing the dependence on fossil fuels,
particularly in areas where there are abundant wind resources. This can improve air quality
and promote sustainable development.

The prime concern with this model is that whether this design will create any additional
resistive force components opposite to the direction of the propulsion. It has been found by the
simulation that a drag will be induced due to addition of turbine. Overall simulation result will
suggest that the overall effect will be same which means the modified design will experience
almost same amount of drag compare to the conventional one. But the addition of turbines may
give the provision of capturing some energy which will offer some benefits for the vehicle as
discussed earlier. A physical structure of the design should be used to carry out wind tunnel
tests which are yet to be done. At first the system may resembles with perpetual motion. But a
careful observation may indicate that the system is trying to recover some of the energy spend
to overcome the aerodynamic drag. The concept of placing symmetrical turbines is presented
for the very first time by us. We believe it requires more research and elaborate analysis which
we expect to continue in future.
In his study he concluded the wind turbine is appropriately designed to extract maximum
amount of energy from the wind to power the electric car. Through the theoretical calculation
on the power generated from the wind, a significant amount of electrical power (about 3.26
kW) is restored to the batteries when the car is moving at a speed of 120 km/h.
The project was successfully achieved by developing a wind energy harvesting system for
portable charger by integrating several components and Supercapacitor as the power storage
unit. The working principle of the system was based on four objectives as derived at the
beginning of this project. Several calculations and testing were performed to identify the most
ideal turbine to be used with the system to perform at its maximum efficiency. The wind
harvesting mechanism was assembled in a waterproof casing since it is to be implemented on
a motorcycle. A universal bracket was constructed with the wind harvesting mechanism which
5
gives an upper hand to the system since it can be mounted on any type of motorcycle with the
aid of bolt and nut. The voltage produced from the DC generator was stepped down to 5.3V
using the DC-DC buck converter. The Supercapacitors were connected in series which was
able to store and produce voltage up to 5.4V being sufficient to power up the Arduino
microcontroller as well as to charge a powerbank simultaneously.
In the proposed project work a mobile battery charger has been investigated with a PWM
charging unit for automobile industry. The hardware realisation as external unit may bring a
new technology to utilise renewable sources and can replace petrol /diesel driven automobile
completely. Further integration of the system directly with the converter unit driving the wheel
not only will save the cost but reduce the extra weight added to automobile and thus will be
able to increase the efficiency.
In this paper, various control strategies and convertor topologies have been investigated and
compared. During the investigation ,among the control strategies used, direct torque control
has many advantages like simple structure ,minimum number of transformation ,efficient
decoupled torque and speed control .Among the convertor topologies investigated SVPWM
has many advantages such as improved power factor, less THD ,and less switching losses.
When the switching frequency is high SVPWM gives improved result. After scrutinizing all
the citied papers, it is found that DTC with SVPWM is a potential candidate for analyzing the
performance and better efficiency of wind electric generators.

PROBLEM IDENTIFICATION
After conducting an extensive review of the existing literature on self-charging systems for
electric vehicles using wind energy, I have identified two critical issues that have been
hampering the overall efficiency of these systems. These issues are the aerodynamic drag and
blade design of the wind turbine, which have led to a meager efficiency rate of only 10%.
To address these problems, I delved further into my research and explored various possible
solutions that could improve the design and efficiency of wind turbines in self-charging
systems. I discovered that the problem of aerodynamic drag could be tackled by redesigning
the shape of the wind turbine blades to minimize the resistance caused by airflow. At the same
time, a more advanced blade design could be implemented to optimize the capture and
conversion of wind energy into electricity.
In addition to improving the aerodynamic drag and blade design, I also found that the
positioning of the wind turbine on the electric vehicle could play a crucial role in increasing
the overall efficiency of the self-charging system. By positioning the wind turbine in a way that
maximizes the exposure to wind flow, electric vehicles can generate more energy while
traveling at higher speeds.
By overcoming the challenges of aerodynamic drag and blade design, we can unlock the full
potential of wind energy and create a more sustainable and efficient transportation system for
the future.
SOLUTION:-
We are designing a new kind of blade that can operate efficiently in high-velocity winds with
negligible loss from aerodynamic drag. By implementing this blade in the self-charging system
for electric vehicles using wind energy, the overall efficiency can be increased by 40% to 70%.
The blade will be connected to a generator that will generate electricity, and this generator will
be mounted on the electric vehicle. The electricity generated by the system will be stored in the
battery of the electric vehicle. The electric motor of the vehicle will draw power from the
battery to move the vehicle.

This new blade design will have an innovative structure that reduces drag and improves the
efficiency of energy capture. The design incorporates unique airfoil shapes, angles, and
curvature that work together to harness the maximum amount of energy from the wind while
minimizing the drag.
Furthermore, the blade will be constructed with lightweight, high-strength materials to ensure
that it can operate in high wind speeds without damage or failure.
Overall, this new blade design holds great potential for increasing the efficiency of self-
charging systems for electric vehicles using wind energy. By harnessing more energy from the
wind with minimal loss due to drag, we can create a more sustainable and efficient mode of
transportation for the future.

prototype design of the self-charging electric vehicle using wind energy and put it to the test in
practical applications. Our team is dedicated to ensuring that the system operates as efficiently

to the design features or materials used. This will allow us to optimize the system's overall
performance and efficiency, bringing us one step closer to a sustainable future.
To achieve this, we will be conducting rigorous testing to assess the turbine blade's performance
under a variety of wind conditions, ranging from low to high wind speeds. We will also be
evaluating the efficiency of the charging system by measuring the amount of electricity
generated and stored in the vehicle's battery. Through careful analysis of the practical data, we
will be able to make informed decisions about any necessary modifications to the design or
materials used in order to optimize the system's overall efficiency.
Our ultimate goal is to create a self-charging electric vehicle using wind energy that is capable
of reducing our dependence on non-renewable sources of energy, while also providing a
sustainable and efficient mode of transportation. With the help of our dedicated team and the
practical data we gather in the upcoming phase of the project, we are confident that we can
achieve this goal and contribute to a more sustainable future for all.

research and development, we can create more sustainable and efficient modes of
transportation that will benefit the environment and society as a whole.
Overall, the self-charging system for electric vehicles using wind energy holds great potential
for creating a more sustainable and efficient mode of transportation for the future. We must
continue to invest in renewable energy research and development to make this technology more
accessible and affordable for everyone. By embracing sustainable practices and reducing our
dependence on non-renewable sources of energy, we can create a better world for future
generations.
