Abstract
Provided is a wireless charging system having different wireless modes, the system comprising: a method of providing a coil having different charging modes in one set, which is performed by providing separate coils or providing a lead wire in the middle of one coil, when the coil having at least two different charging modes is provided in the one set in a receiver for the wireless charging system using non-contact magnetic induction, wherein when one charging mode is selected for one coil set, a status value of the coil for transmitting and receiving wireless power energy is detected, thereby enabling the one charging mode to be selected, and different charging modes is mounted in one wireless charging system so that a charging mode appropriate for optimum conditions can be selected according to states and charging conditions wireless power transmitting and receiving devices.
