Embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and do not have to
It is of the invention in limiting.
Fig. 1 is referred to, Fig. 1 is the flow chart of the preferred embodiment of mobile terminal charging control method of the present invention.Such as Fig. 1 institutes
Show, mobile terminal charging control method described in the embodiment of the present invention, comprise the following steps：
Step S100, when mobile terminal detects connection charger, charger is waited to be provided with output voltage and output electricity
Stream.
In the embodiment of the present invention, when mobile terminal detects connection charger, charger is waited to be provided with output electricity
Pressure and output current.For example, the rising edge for pre-setting the charger tie point of mobile terminal interrupts；When detecting the charging
When the rising edge of device tie point interrupts generation, then it is assumed that mobile terminal detects connection charger.
Usually, the charger tie point of mobile terminal is low level in no connection charger（0 volt of voltage）, because
Charger output voltage is usually higher, such as 4 volts, 5 volts, 7 volts etc., specific voltage swing is because of charger and different；Therefore work as
The charger tie point of mobile terminal, which will be pulled high to charger output voltage, when mobile terminal connects charger turns into high level,
Produced so as to which the rising edge of the charger tie point of mobile terminal interrupts, therefore, mobile terminal is upper according to charger tie point
Rise along whether interruption is produced to judge whether charger inserts.
Specifically：
The wait charger, which is provided with output voltage and output current, to be included：
Mobile terminal judges whether the output voltage changes with output current every the time of setting；The time of the setting,
Preferably 2 seconds；
Detect that the output voltage does not change with output current continuous ten times when mobile terminal, charger is provided with
Output voltage and output current.
Typically, after mobile terminal links with charger, charger needs continuous its output voltage of active accommodation and output electricity
Stream, this adjustment process are usually that regulation in 1 second is once, in the present invention to increase certain redundancy to be arranged to 2 seconds, convenient buffering
Reduce the infringement to mobile terminal.
Step S200, mobile terminal judges whether the output voltage is more than pre-determined threshold with output current, if being more than pre- gating
Limit is then to charger feedback signal；
, it is necessary to which mobile terminal judges whether the output voltage is more than pre-determined threshold with output current in the embodiment of the present invention, if
More than pre-determined threshold then to charger feedback signal.It is specific as follows：
Judge whether the output voltage is more than predeterminated voltage thresholding, to charger feedback first if predeterminated voltage thresholding is more than
Signal；It is preferred that the predeterminated voltage thresholding is 9 volts.
If being less than or equal to the predeterminated voltage thresholding, judge whether the output current is more than predetermined current door again
Limit；If being more than secondary signal is fed back to charger；It is preferred that the predetermined current thresholding is 2 peaces.
In the embodiment of the present invention, the first signal of feedback and the feedback secondary signal signal that only need to be two different, than
The generation for such as feeding back the first signal is to comprise the following steps：
S101 acquisition for mobile terminal present input voltage is V1；
S102 mobile terminals limitation input voltage is that V1/2 lies prostrate (V1 divided by 2);
S103 mobile terminals limitation input voltage is that V1/3 lies prostrate (V1 divided by 3)；
So, the energy variation of acquisition for mobile terminal, charger end can detect that output work takes the lead in becoming original 0.5 times, then
Become 0.333 times, this variable signal charger is considered to feed back the first signal.
For example the generation of feedback secondary signal is to comprise the following steps：
S201 acquisition for mobile terminal present input voltage is V1；
S202 mobile terminals limit input voltage and lied prostrate for V1/3；
S203 mobile terminals limit input voltage and lied prostrate for V1/2；
So, the energy variation of acquisition for mobile terminal, charger end can detect that output work takes the lead in becoming original 0.333 times,
Become 0.5 times again, this variable signal charger is considered to feed back secondary signal.
Step S300, when charger receives, the feedback signal then automatically adjusts the output voltage or regulation is described defeated
Go out electric current, control charger end output predetermined voltage or scheduled current.
In the embodiment of the present invention, the output voltage will be reduced when charger receives the first signal of the feedback；Then drop
The output voltage of the low charger is to predetermined voltage；
The output current will be reduced when charger receives the feedback secondary signal, then reduces the output electricity of the charger
It flow to scheduled current.
Wherein, the predetermined voltage of above-described embodiment is the reasonable voltage that mobile terminal can receive charging, will not be to mobile whole
End surpasses into the voltage of infringement, such as 8V, and the scheduled current is the reasonable electric current that mobile terminal can receive charging, will not be to movement
Terminal surpasses into the electric current of infringement, such as 1.8A.
Therefore the method for the invention is by when mobile terminal detects connection charger, waiting charger to set
Put and complete output voltage and output current；Mobile terminal judges whether the output voltage is more than the door pre-seted with output current
Limit, to charger feedback signal if being more than；The output voltage or institute will be reduced when charger receives the feedback signal
State output current.Make, when mobile terminal is connected with charger and charged, charger end can be controlled in time by mobile terminal
The more rational voltage of output and electric current, accordingly even when leak or limitation function to be present not timely in the restriction scheme of mobile terminal
Play a role or can also ensure the charging safety of mobile terminal during the temporary failure of limitation function.
Certainly, one of ordinary skill in the art will appreciate that realizing all or part of flow in above-described embodiment method,
It is that related hardware can be instructed by charging control program（Such as processor, controller etc.）To complete, described charge control
Program can be stored in a computer-readable storage medium, and the program may include such as above-mentioned each method embodiment upon execution
Flow.Wherein described storage medium can be memory, magnetic disc, CD etc..
