How does wireless cell phone charger for car work?

Any wired charger transfers electricity to the battery of mobile device via an electric cable. Charger receives electricity from the network, with the help of a step-down transformer, lowers the voltage to the desired value, using a small electronic circuit, the electric current is rectified and supplied to the battery of the mobile device. Wireless charging also receives electricity, but from the vehicle’s on-board network, and converts it using induction coils. These coils are able to create an electromagnetic field, and within boundaries of this field to transmit electricity at a distance. The wave energy directly in the battery goes into electrical energy, and thus the battery is charged.

Wireless car chargers work on the same principle, but they take electricity not from 220 Volt network, but from the car's on-board network.
