Title:
WIRELESS CHARGING PANEL, OFFSET DETECTION METHOD FOR WIRELESS CHARGING PANEL, AND WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/035175
Kind Code:
A1
Abstract:
Provided in the present application are a wireless charging panel, an offset detection method for a wireless charging panel, and a wireless charging system. The wireless charging panel comprises a power transmission coil, a detection circuit, a plurality of metal induction coils and a processor. Each metal induction coil arranged on a second flat surface in the wireless charging panel senses whether there is metal directly above the metal induction coil itself, and generates a electrical sensing signal. The processor determines a first detection matrix according to the electrical sensing signal generated by the metal induction coils, and determines, according to the first detection matrix and in a chassis metal detection matrix of a target vehicle, the position of the wireless charging panel relative to a chassis of the target vehicle, so as to further determine charging position offset information of the wireless charging panel according to the position of the wireless charging panel relative to the chassis of the target vehicle. By using the present application, an adjustable range for the alignment of a target charging working area with a wireless charging panel can be enlarged, thereby ensuring that enough adjustment space is reserved for a driver; and the present application has a high applicability.
