Powerpoint Presentation on Wireless power Transmission with emphasis on Wireless Charging & OLEV technologies

1. Wireless Charging & OLEV Technologies

2. OVERVIEW
 WPT : Wirelessly transmitting
electrical energy by means of
Electromagnetic Fields.

3. Why WPT?
 To power our electronic devices we
need 40 million disposable
batteries per year which causes
battery waste.
 Fast.
 Reliable.

4. Why WPT?
 Low maintenance cost.
 30-40% energy is lost during
transmission through wires.
 No wires & hence no e-waste.

5. Why WPT?

6. HISTORY
 Ampere’s Circuital law & Faraday’s
laws of Induction.
 Nikola Tesla inventing Tesla Coil.

7. CLASSIFICATION
WPT
Near Field
Inductive
Coupling
Capacitive
Coupling
Far Field
Microwaves Lasers

8. APPLICATIONS
 Near-Field Energy Transfer
 Electric automobile charging.
 Consumer electronics.
 Far-Field Energy Transfer
 Solar Power satellites.
 Energy to remote areas.

9. WIRELESS
CHARGING
Near Field
Technique.
Inductive
Coupling.

10. Working of Wireless
Charging

11. OLEV
 OnLine Electric Vehicle(OLEV).
 OLEV is the first public transport
system that used a "recharging"
road and was first launched by The
Korea Advanced Institute of
Science and Technology(KAIST).
 Charges wirelessly while moving
using Electromagnetic Induction.

12. Working of OLEV

13. Benefits
 Zero emissions.
 31% operating costs compared to
gas powered counterparts.
 Lower maintenance and
manufacturing costs.
 No charging station necessary.
 Can be stored like regular vehicles.

14. Issues
 Modern power grids cannot handle
OLEV's on a large scale.
 Installation is costly.
 Can run out of power in heavy
traffic.
 40 mph speed limit.
 Cannot operate during power
outages.
