vehicle system charging

1. SOLAR BASED WIRELESS
CHARGING OF DYNAMIC
ELECTRIC VEHICLE

2. 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.

3. Non-radiative WPT
▶ Power is transferred by magnetic fields using inductive
coupling between coils of wire.
▶ In this project we use Inductive coupling.

4. OBJECTIVE
1. T
o develop a system in which we use “RENEWABLE
SOURCE” so we use SOLAR ENERGY.
2. To charge electric vehicle wirelessly when running.

5. NEED OF THIS TECHNOLOGY
▶ As it will encourage 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.

13. WORKING
▶ The solar panel is get charge from sunlight.
▶ Then this power is supply to battery through boost
converter .
▶ Then the DC supply is given as input to inverter from
battery(12v).
▶ After this the inverter convert this 12v(DC) to 220v(AC).
▶ Now this AC supply is fed to transmitting coil.

14. WORKING
▶ By induction power is transfer from transmitting coil to
receiving coil.
▶ As we know that our load is DC so rectifier is used to
convert ac supply to DC and then this power is used by our
load.

15. RESULT

17. EFFICIENCY
▶ FROM ABOVE RESULT WE ARE GETTING EFFICIENCY OF
ABOUT 38.56% AT 2 CM DISTANCE

18. ADVANTAGES
▶ Pollution free
▶ Efficient
▶ Low maintenance cost
▶ Required smaller battery size.
▶ Hassle free
▶ Reliable

19. DISADVANTAGES
▶ High initial cost
▶ Inefficient for longer distances

20. ▶ The dynamic EVs charging are foundational for many future
technology so used for other systems as given :-
1) Traffic lights,
2) Roadside lights
3) Indicators
If it happens, energy can be made available anywhere
without wires running from pole to pole.
