Abstract

The embodiment of the invention provides a wireless charging detection method and device, a mobile terminal and a wireless charging system. The method comprises the steps of determining the first transmission loss of a charging terminal at the first frequency according to the first wireless charging output power when the charging terminal works at the first frequency and the first wireless charging input power of the mobile terminal; determining the second transmission loss of the charging terminal at the second frequency according to the relation between the first transmission loss and the change of the transmission loss along with the working frequency; and determining a wireless charging detection result according to the second wireless charging output power when the charging terminal works at the second frequency, the second wireless charging input power and the second transmission loss. Whether foreign matters exist in the charging terminal and the mobile terminal can be comprehensively determined by referring to the wireless charge output power at least two frequencies and the wireless charge input power, so that the accuracy of foreign matter detection is improved, the misjudgment probability is reduced, and unnecessary troubles brought to a user are reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging detection method, device, mobile terminal, and wireless charging system. Background technique [0002] At present, with the rapid development of communication technology, mobile terminals (such as mobile phones) are used more and more frequently, and users often use mobile terminals in various occasions and places. At the same time, as the functions of the mobile terminal become more and more powerful, the standby time of the mobile terminal becomes shorter and shorter. Due to the inconvenience of using the traditional wired charging method to charge the rechargeable battery of the mobile terminal, taking mobile phones as an example, different types of mobile phones require different adapters, and the charging ports of the charging cables equipped with different types of mobile phones are also different. There are certain differences and are...
