4. Introduction to Wireless Charging
Basically it means charger that don’t need wire
It consists of transmitting circuit & receiving
circuit
Transfers energy using radio frequency, mutual
induction or magnetic resonance

5. History of Wireless Charging
Invention of electromagnetic induction in 1831
Invention of radio waves in 1888
First experiments in wireless power transfer
by Nicola Tesla
Moving of wireless transmission research to
Colorado Springs in 1899

7. Why Inductive Charging?
Radio charging : Short range, low level power transmission
Resonance charging: not established yet ,large level power
transmission
Inductive charging: portable, safe for household activities, mid
range power transmission, light weight

8. What is Inductive Charging?
Uses an electromagnetic field to transfer energy
between two objects
Energy is sent through an inductive coupling to
an electrical device, which can then use that energy
to charge batteries or run the device.
This is usually done with a charging station.

9. Principle of Inductive Charging
Circuit mainly works on the
principle of mutual inductance
Power is transferred from
transmitter to the receiver
wirelessly based on the principle
of inductive coupling

15. Advantages of Inductive Charging
Convenience
Integration
Multiple device wirelessly charging
Portable
Slimmer electronic gadgets
Protected connections
No need of different types of chargers

16. Drawbacks of Inductive Charging
Lower efficiency
Less flexibility
Slow performance
Waste heating

17. Safety Considerations regarding Induced Charging
Non-ionizing radiation from EM field is deemed to be
harmless
Radiation from wireless chargers may be seen as
harmless because they do not transmit intelligence
Huang used a particular magnetic structure to
constrain the leakage flux outside of the pad to lower
the fields

18. Applications of Inductive Charging
 Industrial Usage
 Not Only Mobile Phones
 Hybrid Car Charging
 Usage in Hazardous Environment
 Near Field Charging

19. Future Prospects of Inductive Charging
Charging of electrical vehicles
Long distance charging
Speedy charging
Providing power to medical appliances

20. Standard of Inductive Charging
Qi is an interface standard developed by the Wireless Power
Consortium for inductive electrical power transfer over distances of
up to 4 cm (1.6 inches)
Mobile device manufacturers that are working with the standard
include Asus, HTC, Huawei, LG Electronics, Motorola Mobility,
Samsung, BlackBerry, and Sony
Under the Qi specification, "low power" for inductive transfers
denotes power deliveries below 5 W
