WIPO Patent Application WO/2024/050706
Kind Code:
A1
Abstract:
The present application provides a wireless charging device and a wireless charging system, capable of avoiding damage of near-field communication (NFC) circuits. A surface of the wireless charging device serves as a charging surface and allows for placement of at least one electronic device; the at least one electronic device comprises one or two of an NFC circuit or a wireless charging receiving circuit; the wireless charging device comprises a detection coil array; the detection coil array comprises a plurality of detection areas; the plurality of detection areas respectively correspond to a plurality of charging areas of the charging surface; each detection area has the capability of detecting the signal type of a signal sent by the electronic device, so as to detect whether the electronic device on the charging surface comprises an NFC circuit or a wireless charging receiving circuit. Depending on whether the electronic device on the charging surface comprises an NFC circuit or a wireless charging receiving circuit, the wireless charging device can adjust the power of wireless charging for the electronic device, such that damage of the NFC circuit can be avoided.
