Embodiment
For making the object, technical solutions and advantages of the present invention clearly understand, hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Can perform in the computer system of such as one group of computer executable instructions in the step shown in the flow chart of accompanying drawing.Further, although show logical order in flow charts, in some cases, can be different from the step shown or described by order execution herein.
Fig. 1 is the flow chart of charging method of the present invention, as shown in Figure 1, comprises the steps:
Step 101: when terminal is connected with charging end, terminal detects the output current of charging end.
Before this step, it is the charging current threshold value pre-set that the inventive method pre-sets charging current adjusted value.
Wherein, how to detect the output current of charging end, be the conventional techniques means of those skilled in the art, repeat no more herein.
Step 102: judge whether the output current value detected is less than charging current threshold value, if judged result is for being less than, calculate the product of the output current value detected and the scale parameter pre-set, the product value of gained is first threshold; Adjustment charging current adjusted value is the first threshold calculated.
Wherein, scale parameter be less than 1 percentage.In an embodiment of the invention, scale parameter can be 80%.
The output current value of charging end is less than the charging current threshold value of terminal, illustrates that charging end is transshipped.It is clear to the skilled person that, during the overload of charging end, the output current of charging end be usually in the output-current rating of charging end 100% ~ 120% between, therefore during the overload of charging end this step using output current value be less than the product of scale parameter of 1 as first threshold, and to adjust charging current adjusted value be the first threshold calculated.Like this, when scale parameter be set to desired value as 80% time, ensure that charging current adjusted value is less than the output-current rating of charging end.

Step 104: the prompting output current of charging end does not mate with the charging current threshold value of terminal, and whether inquiry sets charging current.
Can by well known to a person skilled in the art that the mode of man-machine interaction realizes prompting and inquiry in this step.
Step 105: if the external command that terminal receives is for arranging, then obtains the 3rd threshold value of carrying in external command, and judge whether the 3rd threshold value is less than charging current adjusted value; If judged result is less than, then adjusting charging current adjusted value is the 3rd threshold value; Adjustment charging current is charging current adjusted value.Wherein, external command can be the selection of user.
If the 3rd threshold value is less than Second Threshold, known by analysis above, the 3rd threshold value is less than the output current of charging end, and like this, the charging current adjusted value of terminal to take charging current as numerical value be the 3rd threshold value charges, and ensure that charging end safe charging.
By the step 104 and 105 increased further, make user that the charging current of terminal can be set according to the specification of charging end, like this, add the flexibility of the inventive method and the controlling of user.
Before step 105, if namely external command does not set for abandoning, then skip step 105.In this case, the charging current of terminal notifying setting is invalid, and charges according to the charging current adjusted value of charging current to be numerical value be Second Threshold.
