Embodiment 1

[0026] refer to figure 1 , shows a flowchart of steps of a charging method according to Embodiment 1 of the present invention.

[0027] The charging method of the embodiment of the present invention includes the following steps:

[0028] Step S101: When using the charging adapter to charge the mobile terminal, determine the charging voltage currently output by the charging adapter.

[0029] The mobile terminal is equipped with a charging voltage detection module, a sampling resistor, and a charging processing module. The charging voltage module is directly connected in parallel on the charging path between the charging adapter and the charging processing module. The charging voltage detection module can read and calculate through the internal ADC module. output voltage of the charging adapter.

[0030] Step S102: Determine whether the charging voltage is within the first preset range; if yes, perform step S103; if not, perform a setting operation.

[0031] Wherein, the sett...

Embodiment 2

[0040] refer to figure 2 , shows a flow chart of steps of a charging method according to Embodiment 2 of the present invention.

[0041] The charging method of the embodiment of the present invention includes the following steps:

[0042] Step S201: When using a charging adapter to charge the mobile terminal, determine the charging voltage currently output by the charging adapter.

[0043] When charging, one end of the charging adapter is connected to the charging interface of the mobile terminal, and the other end is connected to the charging power supply. When the mobile terminal detects that a charging adapter is connected, the charging process starts.

[0044] The mobile terminal is equipped with a charging voltage detection module, a sampling resistor, and a charging processing module. The charging voltage module is directly connected in parallel on the charging path between the charging adapter and the charging processing module. The charging voltage detection module ...

Embodiment 3

[0073] refer to image 3 , shows a structural block diagram of a charging device according to Embodiment 3 of the present invention.

[0074] The charging device in the embodiment of the present invention includes: a determining voltage module 301, used to determine the charging voltage currently output by the charging adapter when the charging adapter is used to charge the mobile terminal; a judging module 302, used to judge whether the charging voltage is the first Within a preset range; the first charging module 303 is used to, if the judging result of the judging module is that the charging voltage is within the first preset range, and the charging adapter is a standard charging adapter, use the first preset current value to increase the steps value, increasing the output charging current of the charging adapter step by step; the detection module 304 is used to monitor the output voltage of the charging adapter in real time; the determination module 305 is used to determin...

Abstract

The invention provides a charging method. The charging method comprises the steps of determining a currently-output charging voltage of a charging adaptor when the charging adaptor is used for charging a mobile terminal; judging whether the charging voltage is within a first preset range or not; gradually increasing an output charging current of the charging adaptor by taking a first preset current value as an incremental step value if the charging voltage is within the first preset range and when the charging adaptor is a standard charging adaptor; and monitoring an output voltage of the charging adaptor in real time, determining a rule according to the output voltage and a preset current, determining an upper limit value of the charging current, and charging the mobile terminal. The mobile terminal can be used for determining the upper limit value of the charging current with regard to the charging adaptor, and the charging current output from the charging adaptor is self-adapted; and since the charging current output from the charging adaptor can be self-adapted, the problem that the mobile terminal is repeatedly started all the way or charging is stopped when charging is not completed can be prevented.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a charging method and device. Background technique [0002] At present, with the development of science and technology in recent years and the rapid development of mobile terminals, more and more people can use smart mobile terminals, and the popularization and popularization of mobile terminals will become a development trend. [0003] At present, the charging interface of mobile terminals has good compatibility and can be compatible with different types of charging adapters. The power, rated voltage, and rated current of various types of charging adapters are largely different. For convenience, users bring their own charging adapters in mobile terminals. When lost or forgotten to carry, use the non-standard charging adapter to charge the mobile terminal. [0004] In particular, various fast charging adapters have appeared recently, which makes the market of chargin...
