Abstract: A wireless charging method and apparatus are provided. Identification information is transmitted, through a near field communication antenna, to a wireless power transmitter for an authentication process of the electronic device, if the electronic device is put on the wireless power transmitter for wireless charging and a near field communication controller is in an initial or idle state. Wireless power is received through a wireless power receiving antenna from the wireless power transmitter after the authentication process. Wireless charging is performed through a wireless charging controller by using the received wireless power. It is determined whether the wireless charging is complete. A charging completion signal is transmitted, through the near field communication antenna, to the wireless power transmitter based on the determining.

Abstract: A wireless charger for an electronic device is provided, which includes one or more charge cells formed by one or more structures of transmitting inductance coils, each of the charge cells receiving an electronic device, and an electric power supply circuit of transmitting coils. The transmitting coils surround the charge cells on at least two sides, respectively, and generate a uniformly distributed magnetic field such that the magnetic fields, generated by currents in parts of the structure of the transmitting coils, are mutually subtracted out of the charge cells and summarized inside the charge cell in an area in which the electronic device for reception of energy is located.
