WIRELESS CHARGING COIL WINDING METHOD, ELECTRONIC DEVICE, AND COMMUNICATION SYSTEM

This application discloses a wireless charging coil winding method, an electronic device, and a communication system. In the wireless charging coil winding method, based on specifications (for example, a coil thickness and a coil winding width) of a coil to be designed, a coil of any quantity of layers and any quantity of turns can be obtained through combination in any one or more of the following manners: an N-layer 1-turn coil whose N layers of wires are wound in parallel, an N-layer N-turn coil whose N layers of wires are wound in series, an N-layer M-turn coil (N>M) whose N layers of wires are series-parallel-wound and a part of wires are wound in series, and the like. In this way, in a case in which a size of the coil is limited, a multi-layer multi-turn wound coil is designed, and limited coil thickness space, a limited coil winding width, and the like can be fully used, to obtain an optimal impedance and Q value, reduce coil loss, and improve wireless charging efficiency.
