4. INTRODUCTION
The eco-friendly vehicle is the global trend in the automobile industry.
The electrical vehicle (EV) is the most suitable alternative of petroleum vehicles.
The large capacity, weight, expensive price, short life time, and charging time of battery obstruct the
commercialization of EV.
To solve these problems, wireless charging of electric vehicle is introduceded.
5. WHAT ARE EVS (ELECTRIC VEHICLES) ?
An electric vehicle (EV) uses one or more electric motors for propulsion.
An electric vehicle may be powered through a collector system by electricity from
off- vehicle sources, or may be self-contained with a battery or generator to
convert fuel to electricity.
EVs include road and rail vehicles, surface and underwater vessels, electric aircraft
and electric spacecraft.
6. NEED FOR EVS
Global Warming/Climate Change
Rising Prices
Acid Rain
Effect on Human Health
Impact on Aquatic Life by Oil Spills.
7. TYPES OF CHARGING SYSTEMS
Conductive Charging
It utilizes connector between the
Electric power source and vehicle
battery.
This type of charging is utilized in
Residential areas.
Inductive Charging
Wireless charging coupled
with magnetic resonance
to transfer power from a
transmitting pad to a
receiving pad.
Battery Switching
Depleted EV battery pack
is switched with a fully
charged battery pack in
the switching station.
8. WHAT IS WIRELESS CHARGING?
Wireless charging uses an
electromagnetic field to transfer
energy between two objects
through electromagnetic
induction.
Energy is sent through an
inductive coupling to an electrical
device, which can then use that
energy to charge batteries or run
the device.
9. Why not wires???
As per studies, most electrical energy transfer is through wires.
Most of the energy loss is during transmission
On an average, more than 30%
In India, it exceeds 40%
11. Working
In wireless charging there are transmitter and receiver.
Wireless charging uses an electromagnetic field to transfer energy between two
objects through electromagnetic induction.
Wireless Charging Electric Vehicles are built with an on-board pick up device that
allows an electric vehicle to be powered by an underground power transmitter.
It works on the principal of ELECTROMAGNETIC INDUCTION.
The magnetic field is present around the transmitter and receiver coils. It helps to
transfer the energy.
13. ADVANTAGES
80% reduced operating cost than equivalent gas powered vehicles.
Lower maintenance costs than gas powered vehicles.
Pollution free.
Zero recharging time and unlimited range (when operating on an grid road).
Light weight vehicles.
A number of Evs can be charged at a time.
Electrically safe.
Charging is convenient.
14. DISADVANTAGES
Initial installation cost is very high.
Working area is limited.
Currently the speed is limited to 40 miles per hour.
power outage might cause the EVS to run out of charge.
Heat generation is more than traditional charging.
Complex design.
Construction of wireless charging road is required
15. FUTURE SCOPE OF WORK
Due to Global Warming/Climate Change and Rising Prices Of fuels as well as
availability of fuel the EV is perfect solution for stable lifestyle.
Already world is taken huge step towards EV and wireless charging system.
16. CONCLUSION
Charging electric vehicles wirelessly- a reality
Low maintenance cost but high initial cost.
Better then conventional wired system.
Energy crisis can be decreased.
Low power loss
In the future world will be completely wireless
