Description of the drawings
Fig. 1 is that the flow process of the mobile terminal charging current adjustment control method preferred embodiment in the present invention based on temperature is shown
It is intended to.
The functional schematic block diagram of mobile terminal preferred embodiment during Fig. 2 is of the invention.
Specific embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously referring to the drawings embodiment pair
The present invention is further described.It should be appreciated that specific embodiment described herein is only to explain the present invention, and without
It is of the invention in limiting.
As shown in figure 1, the invention provides a kind of mobile terminal charging current adjustment control method based on temperature, its bag
Include：
S100, pre-set for when mobile terminal charges, at regular intervals detect one-shot battery temperature time interval
Value, the charging current corresponding with detected battery temperature, and for when charging current is higher than predetermined current, by the electricity that charges
Stream is gradually reduced to the electric current adjusted value of predetermined current.
In present pre-ferred embodiments, the charging current corresponding with detected battery temperature is referred to through calculating or real
Relation of the mobile terminal obtained by testing when charging, corresponding to its battery temperature and charging current.Such as detect battery temperature
For 45 °, then the charging current that charging current that can be according to corresponding to pre-setting with battery temperature is obtained now be 2A or
Between 1.9A to 2.1A.
Pre-set the corresponding relation between battery temperature and charging current be in order to, according to electric current adjusted value adjustment filling
During electric current, battery temperature can be clearly set to be reduced to the total adjustment magnitude of current required for preset temperature；Why it is not provided with straight
Connect according to detected battery temperature adjustment charging current, be because when mobile terminal charges, even if charging current is reduced to
Predetermined current, the temperature of battery also will not at once be reduced to the reduction of preset temperature, i.e. battery temperature compared to charging current
Reduction has certain retardance；And why be not provided with direct detection charging current, be because that direct detection charging current consumes energy
It is larger and be possible to by rush of current damage detecting element.It will be apparent that arranging the corresponding relation, it is only necessary to mobile whole obtaining
Search the charging current corresponding to it after end-cell temperature, it is extremely convenient, quick, and the action takes mobile terminal resource
Less, consumed energy is few.
Pre-setting time interval value can ensure mobile terminal when charging, and battery temperature is maintained at normal temperature range
It is interior；Why real-time detection is not configured to, if being because detecting battery temperature not in normal temperature range and to the electricity that charges
Stream is adjusted, is needed certain hour, real-time detection to cause the unnecessary energy of mobile terminal with final adjustment battery temperature
Consume and resource occupation；And why be not configured to only detection once, then it is the need to ensure that the flat of charge efficiency and battery temperature
Weighing apparatus, i.e., reduce in time charging current to prevent cell damage when battery temperature is higher than preset temperature, and is less than in battery temperature
Charging current is improved during preset temperature in time to ensure charge efficiency.
By arranging electric current adjusted value, then charging current is adjusted to predetermined current according to electric current adjusted value, can be by original
This needs the charged electrical flow for rapidly changing to change into successively decrease, avoided damaging battery and mobile terminal.
S200, when mobile terminal charges, according to set time interval value, detection battery temperature.
The step refers to timing when being started to charge up by mobile terminal, at regular intervals such as 5S, detects one-shot battery temperature,
To ensure when mobile terminal charges, its battery most of the time be in normal temperature range, will not be due to the too high damage of temperature
Battery.
S300, corresponding charging current is searched according to detected battery temperature.
S400, judge charging current whether higher than predetermined current, and judged result for after being, perform S500.
S500, according to default electric current adjusted value, gradually reduce charging current until its reach predetermined current.
Mobile terminal charging current adjustment control method based on temperature provided by the present invention, as a result of pre- first
If the time interval value charging current corresponding with detected battery temperature, and electric current adjusted value；Secondly fill in mobile terminal
When electric, according to set time interval value, detection battery temperature；Secondly, searched in contrast according to detected battery temperature
The charging current answered；Again, judge charging current whether higher than predetermined current, and judged result for after being, execution step E；
Finally according to default electric current adjusted value, charging current is gradually reduced until it reaches predetermined current；So that so that mobile whole
End can gradually reduce charging current when its charging causes battery temperature too high, reduce battery of mobile terminal and its this body temperature
On the basis of degree, it is to avoid because the change of super-high-current damages battery, affect the service life of battery.
Further, the mobile terminal charging current adjustment control method based on temperature can also include：Work as detection
Enter after charged state to mobile terminal, user can be charged the setting of time.Such as, when mobile terminal detects charging wire
Insertion or after being charged using other modes, ejecting the charging interval arranges window, and user is charged the write or selection of time,
Mobile terminal can be input into the rational charging scheme of charging interval planning according to user.The step is completed by set of time module.
Can also wherein include that step detects mobile terminal current electric quantity, the step is completed by electric power detection module.
After the detection of current electric quantity, the setting in charging interval is carried out, programme planning is carried out, filling as set by user
It is based on the mobile terminal current electric quantity for detecting, mobile terminal electricity filling time is abundant in the electric time, then can arrange
Default electricity and predetermined current are normal value；And within the charging interval set by user, it is current with the mobile terminal for detecting
Based on electricity, it is not enough to be full of mobile terminal electricity, then the maximum that default electricity is battery normal temperature range can be set
Value, predetermined current is corresponding.
Charging interval setting window can stay in display screen certain hour after ejection and await orders in backstage, also sustainable to stop
Stay or disappear after directly reminding, preferred version of the present invention both ensure that user can receive in time to await orders after staying for some time
Information to the setting window will not persistently be stopped when user is reluctant and arranges to carry out set of time in time, again and disappeared
Consumption excessive power.
Further, the electric current adjusted value is additionally operable to when charging current is less than predetermined current, by charging current progressively
Improve to predetermined current.
Further improve the function of electric current adjusted value so that the present invention can not only ensure the service life of battery, it is to avoid fill
High temperature injury when electric, ensures that the charge efficiency of mobile terminal.
Further, the S400 also includes：
Judge charging current whether less than predetermined current, and judged result for after being, perform S500；
