7. Wireless charging is a method of charging batteries without the use of cable or Physical connection
with the device specific AC adaptors. Essentially wireless charging (wireless power transfer or Inductive
Charging or Cord-less Charging) uses electromagnetic fields to safely transfer power from a
transmitting source to a receiving device for the purposes of wirelessly charging (or recharging) a
battery. As the name suggests, it does so without the use of a physical connection.

Inductive charging is based on the possibility of transferring power
through the space between two objects, a transmitting source and a
receiving device in order to charge or recharge a battery without any
physical connection.

11. Benefits of wireless EV charging:
11M.TECH. AUTOMOTIVE ELECTRONICS
Eliminates the need for a charging cable which is prone to damage,
vandalism and potential safety concerns
Improves user comfort and convenience as there is no need to manually
plug in a cable – just park the vehicle over the charging pad and charging
begins
It will Really make a Make Vehicle Autonomous.
Protected connections
Durability
Inductive charging systems can be operated automatically without
dependence on people to plug and unplug. This results in higher reliability.

Inductive charging of electric vehicles at high power levels enables
charging of electric vehicles while in motion (also known as dynamic
charging).

Long distances a challenge for electric vehicles to overcome. Now scientists from Stanford
University have made a significant step towards getting round this problem – by successfully
transferring electricity wirelessly to a moving object. If a car was able to be charged while it
was being driven, then this would solve the problem of limited range and enable vehicles to
travel for potentially unlimited distances. The idea is that a coil on the bottom of a car could
receive electricity from coils that are connected to an electric current that is embedded in
the road.
