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.

Claims

1. 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.

2. The system of claim 1, wherein when a plurality of separate other coils is provided in one set, one of the plurality of coils is selected, thereby enabling the wireless charging mode to is selected.

3. The system of claim 1, wherein when the lead wire is provided in the middle of the one coil, both end terminals of the one coil are selected or one of the both end terminals and a lead wire are selected, thereby enabling the wireless charging mode to be selected.

4. The system of claim 1, wherein when the coil set is provided in plural number, each of the plurality of coil sets is provided with the coil having the different charging modes.

5. The system of claim 1, wherein the coil having the different charging modes is provided only in a transmitter coil or only in a receiver coil.

6. The system of claim 1, wherein the coil having the different charging modes is provided in both the transmitter coil and the receiver coil.
