3. WHAT IS WIRELESS
CHARGING?
 IT IS ONE OF THE METHOD USED TO
CHARGE THE BATTERIES WITHOUT
CABLES OR ADAPTORS.
 THESE ARE USED IN WIDE RANGE OF
DEVICES SUCH AS CELL PHONES
,LAPTOPS , COMPUTERS , MP3 PLAYERS ,
AND OTHER LARGER DEVICES SUCH AS
ROBOTS , ELECTRIC CARS ETC.....

4. WORKING
 THE MAIN COMPONENTS ARE :
 TRANSMITTER.
 ANTENNA .
 RECIEVER.

5. BLOCK DIAGRAM OF WIRELESS TRANSMISSION

6. TYPES OF WIRELESS
CHARGING
 RESONANCE CHARGING.
 INDUCTIVE CHARGING.
 RADIO CHARGING.

7. RESOSNANCE CHARGING
 IT USES THE PHENOMENON OF RESONANCE
WHICH CAUSES THE OBJECT TO VIBRATE
WHEN ENERGY OF CERTAIN FREQUENCY IS
APPLIED.
 TWO COPPER WIRES ARE USED TO
TRANSMIT ONE AT THE TRANSMITTER AND
ONE AT THE RECEIVER.
 WHEN THESE COILS ARE PLACED CLOSE TO
ONE ANOTHER POWER IS TRANSFERRED
 EX: CARS,ROBOTS,VACCUM
CLEANERS,LAPTOP AND OTHER DEVICES
WHICH REQUIRE MORE POWER…

8. RESONANCE CHARGING IN
ELECTRIC CARS

9. INDUCTIVE CHARGING
 IT IS A KIND OF SHORT DISTANCE WIRELESS
CHARGING IT USES THE CONCEPT OF
ELCTROMAGNETIC INDUCTION .
 WHERE THE CHARGER AND THE DEVICE WILL BE
HAVING AN INSULATED COPPER WIRE ONE AT THE
DEVICE AND ANOTHER AT THE CHARGER.
 THE CHARGER CREATES ELECTROMAGNETIC
WAVES USING COIL AND THIS WAVE IS SENT TO
THE COIL OF THE PHONE OR DEVICE AND
CONVERTS TO ELECTRICITY AND HENCE
CHARGES THE BATTERY.
 EX:MP3 PLAYERS , ELECTRIC TOOTHBRUSH,
TRIMMERS ETC….

10. INDUCTIVE CHARGING IN
PHONE

11. RADIO CHARGING
 IT USES RADIO WAVES.
 A TRANSMITTER PLUGGED TO SOCKET
GENERATES RADIO WAVES AND
RECIEVER IS ATTACHED TO THE DEVICE
WITH SAME FREQUENCY AND THE
BATTERY STARTS TO CHARGE.
 EX:WATCHES , HEARING AIDS, WIRELESS
KEYBOARDS AND MOUSE….

12. ADVANTAGES
 PROVIDE CONVENIENCE TO
CONSUMERS.
 EASY TO MAINTAIN.
 CHARGING OF MULTIPLE DEVICE AT A
TIME.
 AS IT IS WIRELESS IT IS ECONOMIC .
 BETTER PORTABILITY.
 ELECTRONIC WASTES WILL BE REDUCED
COMPARED TO WIRELESS .

13. DISADVANTAGE
 APPLICABLE ONLY FOR SMALL
DISTANCES.
 IT IS LESS EFFICIENT.
 MORE POWER LOSS.
 FOR LARGER DEVICES SUCH AS CARS
,STATIONS MAY BE LIMITED.
