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.
