Title:
WIRELESS CHARGING APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/123788
Kind Code:
A1
Abstract:
The present application relates to the field of wireless charging. Disclosed are a wireless charging apparatus and method. The wireless charging apparatus comprises: a receiving coil, wherein the inductance of the receiving coil is less than the inductance of a transmitting coil; a receiving converter, which is connected to the receiving coil and is used for converting an alternating voltage of the receiving coil into an output voltage of the receiving converter, wherein the output voltage is a direct-current voltage; a charging converter, which is connected to the receiving converter and is used for converting the output voltage into a target voltage and then charging a battery; and a controller, which is connected to the receiving converter and the charging converter and is used for adjusting the output voltage of the receiving converter when the battery is charged in a second charging mode, such that the charging converter meets working requirements, wherein the second charging mode is a quick charging mode which satisfies a target private charging protocol.
