Wireless power transmission (WPT) allows for wirelessly transmitting electrical energy, reducing the reliance on disposable batteries and associated e-waste. The document highlights the application of WPT in wireless charging and the Online Electric Vehicle (OLEV) system, which offers benefits like zero emissions and lower operating costs but faces challenges such as high installation costs and limitations in power grid capabilities. Overall, WPT offers a promising solution for powering electronic devices and modern transport systems.

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.

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.
