Abstract

The invention provides a wireless charging control method and circuit, and a terminal device. The wireless charging control method is applied to a wireless charging control circuit in a terminal device. The wireless charging control circuit includes a wireless charging receiving coil which has at least two operating states, and the inductance value of the wireless charging receiving coil in each operating state is distinctly different. The wireless charging control method includes the steps: acquiring an induced voltage of the wireless charging receiving coil; and according to the induced voltage, controlling the wireless charging receiving coil to operate according to the corresponding operating state. Therefore, in the wireless charging control method and circuit, and the terminal device, the charging state of the terminal device is not fixed, and the charging state of the terminal device can be flexibly adjusted according to the induced voltage of the wireless charging receiving coil, thereby ensuring the wireless charging performance of the terminal device, so as to preferably satisfy the demand of users and achieve a good user charging experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless charging, and in particular, to a wireless charging control method, circuit and terminal equipment. Background technique [0002] With the rapid development of the wireless charging technology, the use of the wireless charging function in terminal devices (such as mobile phones, tablet computers, etc.) is becoming more and more common, and the terminal devices with the wireless charging function are favored by many users. [0003] At present, when the wireless charging function is used, the charging state of the terminal device is generally fixed. In this way, the wireless charging performance of the terminal device is poor and cannot better meet user needs. Contents of the invention [0004] Embodiments of the present invention provide a wireless charging control method, a circuit, and a terminal device, so as to solve the problem of poor wireless charging performance of ...
