Problems solved by technology

[0004] The purpose of the present invention is to provide a fast charging method and charging device to solve the problem that the existing technology provides the charging adapter with a constant, single large charging current to forcibly charge the battery cell of the mobile terminal. The control of charging with a large current and the failure to control the charging current may easily cause the problem of overcharging the battery cell

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0026] In the embodiment of the present invention, "first" in "first charging interface", "first power line", "first ground line" and "first controller" all refer to each other. "Second" in "second charging interface", "second power line", "second ground line" and "second controller" are also referred to.

[0027] It should be noted that the charging adapter in the embodiment of the present invention includes: a power adapter, a charger, an IPAD, a smart phone, and other termina...

Abstract

The invention is suitable for the field of a mobile terminal and provides a quick charge method and system. A second controller sends a quick charge request to a first controller; the first controller feeds back a quick charge permission instruction to the second controller; the second controller sends a notification request for obtaining voltage value of a battery core to the first controller; the first controller obtains the voltage value of the battery core through a battery core connector and sends the obtained voltage value of the battery core to the second controller; the second controller finds out a current regulation instruction matched with a threshold value range where the voltage value of the battery core locates from a threshold value range table, and sends the current regulation instruction to a regulator circuit; and the regulator circuit carries out current regulation according to the current regulation instruction, and outputs a power supply signal after current regulation. Therefore, before the battery core of the mobile terminal is subjected to quick charge, the mobile terminal is asked whether to accept quick charge; and in the charging process, the charging current is controlled, thereby effectively preventing the battery core from being charged excessively.

Description

technical field [0001] The invention belongs to the field of mobile terminals, in particular to a fast charging method and system. Background technique [0002] With the progress of the times, the Internet and mobile communication networks provide a large number of functional applications. Users can not only use mobile terminals for traditional applications, such as: use smart phones to answer or make calls; at the same time, users can not only use mobile terminals for web browsing, picture transmission, games, etc. [0003] With the increase in the frequency of use of mobile terminals, mobile terminals need to be charged frequently; in addition, as users demand for charging speed, there are many mobile terminals that do not monitor the charging current and can accept relatively large current charging (for example, the charging current is 2 amps ( A)). At the same time, many charging adapters have also been born, through which charging adapters can be used for constant cha...
