This project report summarizes the development of a solar-based wireless EV charger using inductive coupling. The system uses a solar panel to charge a battery bank, which provides DC power to a transmitting coil. Through electromagnetic induction, this transfers power wirelessly to a receiving coil connected to an electric vehicle battery. Testing showed the system could efficiently charge an EV over short distances. While the initial cost is high, wireless charging could help expand electric vehicle use in remote areas without transmission lines and reduce pollution by eliminating the need for large onboard batteries. Future work will aim to improve efficiency over longer transfer distances.

3. INTRODUCTION
WHY DO WE NEED FOR WIRELESS POWER
TRANSFER ?
The transmission of energy from one place to other
without cables.
WPT MAINLY FALLS INTO TWO PARTS :
Radiative WPT : This is basically for longer
distances transmission.
Non-Radiative WPT : This is basically for short
distances transmission.

4. Non-radiative WPT
Inductive coupling refers to the phenomenon that exists when a magnetic
field created by an electrical current induces an effect on something
else. When this happens, the two then become mutually reactive, or
coupled, by the inductive effects of the magnetic field. For example,
when an electrical current passes through a wire, the electromagnetic
field created can induce an electrical current in another wire, causing
the two to be inductively coupled. Power is transferred by magnetic
fields using inductive coupling between coils of wire.
In this project we use Inductive coupling.

5. NEED OF THIS TECHNOLOGY
The use electric vehicle even in remote areas where transmission
line are not present, as it is solar driven.
Reduce the need of large and heavy battery for electric vehicle.
No need to stop for charging as it can charge continuously when
in operation.
This also contribute in reducing pollution.

6. LITERATURE REVIEW
The development of wireless power transfer is traceable to the
work done by late Nikolas Tesla, who discovered
and demonstrated the principles behind this phenomenon.
The basic working principle of wireless power transfer
by induction is, the power is transferred by the process
of electromagnetic induction two objects which are having same
resonant frequency and in magnetic resonance at powerfully
coupled rule tends to exchange the energy.

10. WORKING
The solar panel is get charge from sunlight.
Then this power is supply to battery
Then the DC supply is given as input through switch to
transistor from battery(3.7v).
After this the goes to circular coil and current will induced
in receiving coil and induced current will charge the
vehicle

11. WORKING
By induction power is transfer from transmitting coil
to receiving coil.

12. EFFICIENCY
Research presents a wireless DC-to-DC power transfer over
a short distance. In short distance is approx. 90%
As the distance increases efficiency decreases.
