WIPO Patent Application WO/2023/134341
Kind Code:
A1
Abstract:
Provided is a wireless charging device. The wireless charging device comprises: a first coil, which is used for receiving electromagnetic energy and converting the electromagnetic energy into electric energy, so as to wirelessly charge the wireless charging device; and a second coil, which is used for transmitting electromagnetic energy, so as to wirelessly charge an electronic device that receives the electromagnetic energy, wherein the size of the second coil is different from the size of the first coil. When an electronic device is wirelessly charged by means of the wireless charging device, the size of a second coil can be adapted to the size of a receiving coil in the charged electronic device, and the charging efficiency of the wireless charging device itself is also not affected, thereby avoiding the problem in the relevant art of a low charging efficiency caused by using a first coil to wireless charge another electronic device.
