Abstract

The embodiment of the invention discloses a wireless charging method and device. The wireless charging method comprises the following steps: receiving a charging signal transmitted by wireless charging equipment, and charging a battery of a terminal according to the charging signal, obtaining the current electric parameters of the battery in the battery charging process, then obtaining the charging parameters of the battery according to the electric parameters, and sending the charging parameters to the wireless charging equipment so that the charging signal transmitted by the wireless charging equipment is correspondingly adjusted by the wireless charging equipment according to the charging parameters. Through the scheme, the terminal can be controlled for charging through the wireless charging equipment, and compared with the prior art, the charging signal does not need to be adjusted on the side of the terminal, so that the problem of high heat loss caused by an existing wireless charging manner is solved, and the utilization efficiency of energy sources is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a wireless charging method and device. Background technique [0002] With the development of the Internet and mobile communication networks, as well as the rapid development of terminal processing and storage capabilities, a large number of applications have been rapidly spread and used; commonly used applications are convenient for users to work and live. , There is no shortage of newly developed applications that have also entered the daily life of users, improving the quality of life of users, the frequency of using terminals, and the sense of entertainment in use. [0003] The existing lithium battery charging, due to the characteristics of lithium batteries, the charging current requirements are different when the power is different. When the voltage is low, it can only be charged with a trickle. In the constant current charging stage, it can be charged with...
