Embodiment Construction

[0111] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0112] figure 1 It is an example diagram of the fast charging process of the embodiment of the present invention.

[0113] Such as figure 1 As shown, the communication process of fast charging can be roughly divided into the following five stages:

[0114] Phase 1:

[0115] The mobile terminal can detect the type of the adapter through D+ and D-, and when it is detected that the adapter is a non-USB charging device, the current absorbed by the mobile te...

Abstract

In the embodiment of the invention, a mobile terminal identifies the type of an adapter and actively starts a quick charging request, so the mobile terminal can shake hands with the adapter so as to determine charging parameters; the adapter can use a segmented constant current mode to charge the battery of the mobile terminal, thus ensuring the quick charging process to be safe and reliable.

Description

technical field [0001] Embodiments of the present invention relate to the charging field, and more specifically, relate to a fast charging method, a mobile terminal and an adapter. Background technique [0002] At present, mobile terminals (such as smart phones) are more and more favored by consumers, but the mobile terminals consume a lot of power and usually need to be charged frequently. As the battery capacity of the mobile terminal becomes higher and higher, the charging time becomes correspondingly longer. How to realize fast charging needs to be solved urgently. [0003] In the prior art, in order to achieve the purpose of fast charging, the output current of the adapter is directly increased without considering the capacity of the mobile terminal, which will cause the mobile terminal to overheat or even burn out, and reduce the service life of the mobile terminal. Contents of the invention [0004] The present application provides a fast charging method, an adapt...
