Abstract
A car representing an electrical power source includes a car body and a steering wheel, and the steering wheel can recharge the battery of a portable electronic device within close proximity. The steering wheel includes a rim and an emitting module. The emitting module includes an emitting coil and a shielding layer covering the emitting coil. The emitting coil is electrically powered from the car and configured to convert AC power to electromagnetic waves of specific frequency and emit the electromagnetic waves to the receiving module of the electronic device, such that the receiving module receives and converts the electromagnetic waves to electrical power to charge the battery of the electronic device. The present disclosure further provides a car and a wireless charging system.
