3. 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 introduced

4. WHAT ARE Evs?
 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.

8. MODES OF CHARGING

9. CONSTRUCTION OF ROAD FOR EVs

10. ADVANTAGES
 Lack of wires
 No overheating
 Electric cars are energy efficient
 Electric cars reduce emissions
 Electric cars require lower maintenance

11. DISADVANTAGES
 Electric cars can’t travel as far
 Work area is limited
 Electric cars are sometimes more expensive

12. APPLICATIONS
Public Transportations
Military
Spaceflight
Aviation

13. CONCLUSION
Wireless charging operates within a narrow band of efficiency of 88-93%
Its efficiency is about 97% so it will minimize the heat losses during charging
and battery life and efficiency will get increased. Size of the battery will also get
Reduced and as a result of it cost will get also get decrease
