How Does Wireless Charging Work?

Wireless charging, also known as inductive charging, uses electromagnetic fields to transfer energy between two coils—one located in the charging station (or charging pad) and the other in the electric vehicle. The process begins when an electric current is passed through the charging pad, creating a magnetic field. This magnetic field is then detected by the receiver coil in the vehicle, which converts the magnetic energy back into electrical energy to charge the vehicle’s battery.

While wireless charging systems for electric vehicles are similar in concept to wireless charging technologies already used for smartphones and other devices, the scale and power required for EV charging are significantly greater. For this reason, the development of wireless EV charging systems has required advancements in magnetic resonance technology, which allows for the transfer of energy over a greater distance and with greater efficiency.

There are two main types of wireless charging technologies currently under development:
