WIRELESS CHARGING DEVICE, TO-BE-CHARGED DEVICE, AND CHARGING

A to-be-charged device includes at least two receiving branches, a charging control module, and a battery. Each receiving branch is separately connected to the charging control module and the battery. Each receiving branch is respectively coupled to a transmitting branch in a wireless charging apparatus, an electromagnetic signal transmitted by the coupled transmitting branch is received, and the received electromagnetic signal is converted into charging voltage and charging current of the battery of said device. The charging control module generates, according to at least one of the charging voltage of the battery, the charging current of the battery, the voltage of each receiving branch, and the current of each receiving branch, feedback information instructing the wireless charging apparatus to adjust the transmitted power of the transmitting branch, and feeds back to the wireless charging apparatus.
