Abstract

The invention relates to a wireless charging method and device and a storage medium, and belongs to the technical field of wireless charging. The method comprises the following steps: power transmitting equipment charges power receiving equipment by adopting first transmitting power; in the process of charging by adopting the first transmitting power, obtaining a first power loss; and if the firstpower loss is greater than a first threshold value, charging the power receiving equipment by adopting second transmitting power, wherein the second transmitting power is smaller than the first transmitting power. In the embodiment of the invention, when the power transmitting equipment detects that the power loss is greater than a certain threshold value, the transmitting power is reduced, so that the potential safety hazard caused by overheating of foreign matters in a short time due to overlarge transmitting power can be avoided, and the safety and reliability of wireless charging are improved; moreover, the power receiving equipment can be continuously charged, charging interruption is avoided, and the continuity of wireless charging is improved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of wireless charging, and in particular, to a wireless charging method, device, and storage medium. Background technique [0002] At present, for the wireless charging solution based on the principle of electromagnetic induction, foreign object detection (Foreigner Objects Debris, FOD) must be carried out during the charging process to ensure safety. [0003] Alternating electromagnetic induction will cause metal foreign objects (such as coins, metal sheets, bank card chips, etc.) in the electromagnetic field to generate eddy current effects, which will cause the metal foreign objects to generate heat and pose a threat to charging safety. In related technologies, the charger detects foreign objects during wireless charging, and stops charging when it is determined that there are foreign objects. [0004] The processing method provided by the related technology is relatively simple. ...
