Wireless charging
has been around since the 1990’s. It has been used in mobile phones, consumer
gadgets and medical devices. Recently, this kind of technology is being
introduced in electric vehicles as well.
Wireless charging is also called inductive charging. It makes use of two pads: a transmitter of electromagnetic fields and a receiver which converts them back to electricity which charges the battery. This technology reduces the risk of electric shocks because the pads can be entirely covered but it is also less efficient in transmitting electricity.

This technology reduces the risk of electric shocks because the pads can be entirely covered but it is also less efficient in transmitting electricity.
The developments being made in inductive charging are focused mainly on more efficient or almost lossless methods of delivering electricity from one pad to the other. Tests are also being made whether it is feasible to lay down wires and charging stations in parking areas and along roads to minimize the charging time for electric vehicles.
Universities who
have made news and developments about inductive charging include the Utah State
University (Energy Dynamics Laboratory), Massachusetts Institute of Technology
(Professor Marin Soljačić) and the Korea Advanced Institute of Science
and Technology.
