Abstract

The application provides a wireless charging receiving device, a wireless charging method and system, and a terminal device, and relates to the technical field of terminals for reducing energy loss ofa transmitting coil and a receiving coil. The device comprises: a control unit, a receiving coil, a rectifying and filtering unit, a first voltage converting unit and a battery cell module; wherein the control unit is configured to transmit a first control signal to a wireless charging transmitting device and output a second control signal to the first voltage converting unit when the type of thewireless charging transmitting device belongs to a first preset type set and the output voltage of the battery cell module is within a preset range; the receiving coil is configured to sense a firstelectromagnetic wave to generate the first alternating current; the rectifying and filtering unit is configured to convert the first alternating current into the first direct current; the first voltage converting unit is configured to convert the first direct current into second direct current under the control of the second control signal; and the battery cell module is configured to be charged by the second direct current. The wireless charging receiving device is used for wireless charging.

Description

technical field [0001] The present application relates to the field of terminal technology, and in particular to a wireless charging receiver device, a wireless charging method, system, and terminal device. Background technique [0002] Wireless charging technology (Wireless Charging Technology) refers to the charging method in which the charger inputs electric energy into the electric device in a non-contact manner. Since wireless charging technology has many advantages such as avoiding the exposure of the conductive contacts of the charger and the electric device, simplifying the operation of the user when charging, and reducing the wear and tear between the charger and the electric device, the application prospect of the wireless charging technology is very broad. [0003] In general, the process of wireless charging includes: the wireless charging transmitter device converts the electrical energy of the grid power supply into high-frequency alternating current (Alternati...
