Document Type and Number:
WIPO Patent Application WO/2023/221702
Kind Code:
A1
Abstract:
The present application discloses a wireless charging coil winding method, an electronic device, and a communication system. In the wireless charging coil winding method, according to the specification of a coil to be designed (such as the thickness of the coil and the winding width of the coil), coils each having any number of layers and any number of turns comprising any one or more of the following coils can be used: a coil having N layers and one turn wound by connecting N layers of wires in parallel, a coil having N layers and N turns wound by connecting N layers of wires in series, a coil having N layers and M turns (N>M) wound by connecting N layers of wires in series and in parallel and wound by connecting some wires in series and the like. Therefore, when the coil size is limited, a wound coil having a plurality of layers and a plurality of turns can be designed, such that the limited coil thickness space, the coil winding width and the like can be fully used, thereby obtaining optimal impedance and Q value, coil loss is reduced, and the wireless charging efficiency is improved.
