Based on above-mentioned mobile terminal hardware configuration and communications network system, each embodiment of the inventive method is proposed.
The present invention provides a kind of mobile terminal staged charging method, implements in mobile terminal staged charging method first
In example, reference picture 3, the mobile terminal staged charging method includes：
Step S10, the real-time voltage of battery, real-time current and resistance are counted in preset time is based on mobile terminal
Calculate, to obtain the open-circuit voltage of battery；, to obtain the open-circuit voltage of battery；
When mobile terminal is in charged state, the battery of mobile terminal can connect charge circuit, and charge circuit is general
By applying charging voltage, charging current etc. to battery, the electricity supplement of battery is realized.Flow through the size of the charging current of battery
The charge efficiency of battery is influenced whether, and the size of charging current be not different in the same time, because battery was charging
Cheng Zhong, electricity and voltage can change, and the real-time change of electricity voltage also influences whether the real-time change of charging current
Change.In addition, in whole charging circuit, the presence of resistance can also influence the charge efficiency of charging current, and present in battery
Resistance mostlys come from the internal resistance of cell.
Staged charging refers to battery in charging process, is charged by battery of larger current, and will be filled in battery
During Full Charge Capacity, charging current is adjusted back so that battery can quickly realize the charging scheme that electricity is full of.Staged charging scheme pair
The quality of materials of battery and stability requirement are high, and because the change of electric current is cataclysm in a short time, can to a certain degree
Damage battery.
Because battery can produce open-circuit voltage in charge circuit, electricity voltage is present in the change of open-circuit voltage and battery
Certain incidence relation.The open-circuit voltage refers to terminal voltage of the battery under open-circuit condition.The open-circuit voltage of battery is equal to
The difference of battery electrode potential of the anode electrode potential of battery and negative pole (during without electric current by the two poles of the earth) in open circuit.Electricity
Voltage is interrelated with charging current, therefore the present embodiment can influence the change of charging current indirectly by open-circuit voltage, with
The charging current that battery is most adapted to is supplied to, so as to be not used in changing charging current suddenly in staged charging scheme.
To ensure gradually changing for charging current, mobile terminal is detected every preset time to battery.When default
Between be usually terminal the time interval that pre-sets of production business men, detected every preset time, can be more accurate
Ground obtains the Parameters variation of battery, is got at interval of preset time detection in the real-time voltage, real-time current and battery of battery
Resistance.Real-time voltage refers to the current voltage swing of battery, can reflect the electricity that battery is supplemented, and real-time current is referred to
By the size of current of battery.Exist between real-time voltage, real-time current and the internal resistance of cell and open-circuit voltage and certain associate pass
System, can be influenced each other each other, and its logical relation can be determined by actual charging circuit, and the logical relation meaning determined
Taste, which mobile terminal, to solve to get open-circuit voltage by real-time voltage, real-time current and resistance.
It will be explained below by a specific example：
Reference picture 10, mobile terminal can get the voltage V of charging circuit by the electrical potential difference at battery a, b two ends, fill
Internal resistance of cell R in circuit can be directly obtained by the supplemental characteristic in battery, and battery can get and flow through battery
Charging current I.So, in Figure 10 charging circuit, open-circuit voltage OCV can obtain its logical relation according to circuit rule and be
OCV=V-IR.I.e. the value of open-circuit voltage can be calculated by circuit voltage, resistance and battery current and obtained.
Step S20, the default grading current in default battery specifications table is obtained based on open-circuit voltage；
Production firm preset the specifications parameter form of battery in the terminal, and represent production firm will look after and guide
The corresponding various adaptation datas of specifications parameter together it is built-in in the terminal.After open-circuit voltage is got, mobile terminal
Default grading current corresponding with open-circuit voltage can be directly obtained according to the numerical value of open-circuit voltage.Different open-circuit voltage correspondences
Different charging currents, the balanced balanced current number that charge efficiency and charging safety are ensured under the open-circuit voltage is represent respectively
Value.The default grading current refers to that the unified charging of use is electric when the numerical value of open-circuit voltage is in specific scope
Stream.The default grading current is the optimal charging current for weighing charging safety and charge efficiency, and charging peace is ensured to greatest extent
Entirely, while not violating the essence of staged charging technique scheme.
As described above, default grading current shows different numerical value under different open-circuit voltages, i.e. in mobile terminal
It is also different based on the default grading current accessed by different open-circuit voltages in charging process, there are multiple default grading currents
It is for selection.Under different open-circuit voltages, acquisition for mobile terminal to the charging current for being best suited for present battery charged state,
Substantially to avoid battery from being caused battery damage by current-jump is excessive.The situation of battery damage can include following feelings
Condition：Battery material is denatured, battery electrolyte loss increase, battery plus-negative plate passivation etc..Damage situations described above will be very big
Stability in ground influence battery charging process, and stabilization of the battery in charging process is used, and can ensure mobile terminal
Normal operation.Therefore, the default grading current of gradual change can ensure that battery can better adapt to electricity in charging process in proper order
Stream slight saltus step so that battery in charging process hold mode relatively stablize.
Step S30, default grading current is adjusted to by the current charging current of battery.
Reference picture 11, if being fallen back in the charging circuit of mobile terminal only with a kind of charging current in charging current
During the charging coda stage of low current, battery subjects larger electric current cataclysm.And utilize stepped electric current graded scheme, then
This negative effect can be avoided.Because in the present embodiment, open-circuit voltage is detection calculating acquisition after each preset time, because
This, open-circuit voltage is in variation, then the default grading current got according to open-circuit voltage is also that certain change is presented
Dynamic trend.Reference picture 12, charging current is successively decreased step by step, after the adjustment by repeatedly presetting grading current, charging current
Variation tendency becomes smooth gentle.Certainly, set default grading current is more, and the change curve of its electric current will be more smooth.
And the current curve more seamlessly transitted, it is meant that battery in charging process institute by battery life matter caused by electric current cataclysm
The loss of amount will become lower.
Specifically, the present embodiment is in the real-time voltage in charging circuit is detected after one section of preset time, real-time current
And the internal resistance of cell, calculate the real-time open-circuit voltage of present battery, and the default battery specifications table looked after and guided according to production firm,
Mobile terminal inquires the default grading current of Corresponding matching by open-circuit voltage, by mobile terminal use default grading current for
Battery charges.
Alternatively, it is assumed that the differentiation precision of open-circuit voltage is higher in battery specifications table, then the default ladder electricity classified
Stream is more.And it is higher to distinguish precision, then battery is in charging process, and open-circuit voltage is corresponding default when changing by a small margin
Grading current will also change by a small margin, then battery can be more easily transitioned into new during charging current changes
In the charged state of default grading current, cell safety of the battery in charging process is further ensured.
In technical scheme, the real-time electricity of mobile terminal battery first in preset time is based on mobile terminal
Pressure, real-time current and resistance are calculated, to obtain the open-circuit voltage of battery；It is then based on open-circuit voltage and obtains default battery
Default grading current in specification table；The current charging current of battery is finally adjusted to default grading current.Basis of the present invention
The battery specifications of battery, offer charge efficiency highest is filled under battery different tolerance degree situation by way of progressively adjusting
Electric current, it is to avoid the difference between current of rapid jumping greatly extends the service life of battery, kept away to the impact damage of battery material
Exempt to charge unstable and cause battery the potential safety hazards such as short circuit.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole
Staged charging method second embodiment is held, reference picture 4, the difference between the second embodiment and first embodiment is,
It is described obtained based on open-circuit voltage in default battery specifications table default grading current the step of include：
Step S21, is that battery specifications table sets the voltage ladder of default ladder level interval, and in each voltage ladder area
Between corresponding default grading current is set；
Step S22, gets the voltage ladder interval based on open-circuit voltage, and get correspondence based on voltage ladder interval
Default grading current.
The numerical values recited of open-circuit voltage affects the value of default grading current, because the change of open-circuit voltage reflects electricity
The floating voltage compensation ability that pond can be born.Therefore the size of open-circuit voltage is when changing, what battery currently can bear
Charging current also changes therewith.Assuming that not being adjusted to charging current now, charged with the electric current for adapting to battery, that
Situation will occurs in battery：
1st, real-time current is less than the maximum charging current that can bear, and charge efficiency can not be maximized；
2nd, real-time current is more than the maximum charging current that institute can be ripe, and battery there may be certain stability threat.
The core of the present embodiment is that the charging current that can bear battery under different open-circuit voltages carries out ladder
Formula is distinguished.The voltage ladder that battery specifications table is set into default ladder level is interval, and each voltage ladder is interval each
From correspond to the shared default grading current in the interval, i.e., when the numerical value of open-circuit voltage falls in voltage ladder is interval, then only use
One default grading current is charged for mobile terminal, and the stabilization of charging current so can be stably ensured relatively.
For example, open-circuit voltage is divided into three default ladder levels, the first ladder, the second ladder and the 3rd rank by the present embodiment
Ladder.Different ladders represent open-circuit voltage in different intervals, and are made with first voltage value, second voltage value and third voltage value
For the line of demarcation of each ladder, according to first voltage value, second voltage value and third voltage value, ladder where open-circuit voltage is determined,
And corresponding grading current is got according to place ladder.
Open-circuit voltage is bigger, then proves that the upper limit for the maximum current that battery can be born is bigger.Therefore in the present embodiment,
Third voltage value>Second voltage value>First voltage value, corresponding, the 3rd grading current>Second grading current>First ladder electricity
Stream, according to the value of open-circuit voltage, in value and the first voltage value of open-circuit voltage, second voltage value and third voltage value progress pair
Than, you can get the grading current value being most adapted in default battery specifications table.
Specifically, it is assumed that first voltage value is 5V, second voltage value is 10V, and third voltage value is 15V, if open-circuit voltage
For 8V, due to 5V<8V<10V, i.e. open-circuit voltage are in the interval of first voltage value and second voltage value, and now mobile terminal is obtained
Take the first grading current；If open-circuit voltage is 13V, the grading current of acquisition for mobile terminal second；Similarly, if open-circuit voltage is
20V, the then grading current of acquisition for mobile terminal the 3rd.
The ladder of the open-circuit voltage specification is divided into three or more than three.
It should be noted that in the present embodiment, open-circuit voltage specification is not only only set to three specifications, can be with root
According to actual conditions be set to it is multiple more refine more accurate ladder specification so that the interval judgement of open-circuit voltage is finer,
And then improve the charging current that battery is adjusted.
Further, on the basis of mobile terminal staged charging method second embodiment of the present invention, propose mobile whole
Staged charging method 3rd embodiment is held, reference picture 5, the difference between the 3rd embodiment and second embodiment is,
It is described to set the voltage ladder of default ladder level interval for battery specifications table, and set corresponding in each voltage ladder interval
Also include before the step of default grading current：
Step S23, the predetermined registration operation inputted based on user gets the interval default ladder level of voltage ladder.
The voltage ladder predetermined registration operation that can be inputted by User Defined of interval is divided, so as to need of the user according to oneself
The realistic existing assurance to charging process and charge efficiency.Predetermined registration operation refers to that user sets voltage ladder on mobile terminals
Interval delamination criterion, for example, user can be 12V, 9V, 6V, 3V as threshold value by setting using open-circuit voltage, so that by 3V
Open-circuit voltage to 6V is interval as a ladder level, similarly, can regard 6V to 9V open-circuit voltage interval as a ladder
Level, regard 9V to 12V open-circuit voltage interval as a default ladder level of ladder level three.Certainly, user can be set
Other threshold values so that voltage ladder interval other forms are divided into different ladder levels.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole
Staged charging method fourth embodiment is held, the difference between the fourth embodiment and first embodiment is, the battery
Specification table also includes ladder efficient current, the default grading current obtained based on open-circuit voltage in default battery specifications table
The step of also include：
When open-circuit voltage is less than preset voltage value, default ladder efficient current is obtained；
The step of charging current that battery is current is adjusted to default grading current includes：
The current charging current of battery is adjusted to ladder efficient current.
Assuming that the open-circuit voltage of current battery is not within the scope of ladder specification, i.e., open-circuit voltage is less than or equal to the
One magnitude of voltage, now end cell can be directly obtained default ladder efficient current.The ladder efficient current was referred at end
End-cell most efficient charging current in the range of can bearing.If open-circuit voltage is less than preset voltage value, according to original
Charging current for charging, then the end cell time at full charge will greatly increase.The ladder efficient current is mobile terminal
The efficient current that production firm is got by looking after and guiding repeatedly, therefore when open-circuit voltage is less than or equal to first voltage value, move
Dynamic terminal obtains default ladder efficient current, and is charged by battery of ladder efficient current.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole
The embodiment of staged charging method the 5th is held, reference picture 6, the difference between the 5th embodiment and first embodiment is,
Real-time voltage, real-time current and the resistance of the battery in preset time is based on mobile terminal are calculated, to obtain electricity
The step of open-circuit voltage in pond, includes：
Step S11, the real time temperature of battery is obtained every preset time, and based on real time temperature and default battery specifications
Table obtains the real time resistance of battery；
Step S12, real-time voltage, real-time current and real time resistance based on battery are calculated, to obtain present battery
Open-circuit voltage.
In the battery, resistance can change with the change of battery temperature, and the change of resistance can cause open circuit electricity
The change of pressure.Assuming that acquisition open-circuit voltage is calculated with fixed resistance always, then open-circuit voltage will not be accurate.Therefore, move
Dynamic terminal needs to get the real time temperature of battery every preset time.Because the material of battery is certain, its real time temperature
Influence to resistance can be also directly obtained by battery specifications table, therefore can inquire electricity under present case by real time temperature
The real time resistance in pond.
Get after real time resistance, mobile terminal can directly be counted according to real-time voltage real-time current and real time resistance
Calculate, obtain the real-time open-circuit voltage of battery.The step is consistent with first embodiment principle, and therefore not to repeat here.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole
Staged charging method sixth embodiment is held, reference picture 7, the difference between the sixth embodiment and first embodiment is,

Electric current and resistance are calculated, the step of open-circuit voltage to obtain battery after also include：
Step S40, judges whether the difference of the electromotive force of open-circuit voltage and battery is more than first threshold；
Step S50, when the difference of open-circuit voltage and the electromotive force of battery is more than first threshold, performs and obtains default ladder
The step of electric current；
The present embodiment introduces the incidence relation of the electromotive force of open-circuit voltage and battery.The open-circuit voltage of battery is less than electronic
Gesture, and electromotive force refers to that positive charge is transported to positive pole ability by battery from negative pole, electromotive force is numerically equal to battery two ends electricity
The voltage sum that pressure and battery internal resistance are consumed.Because the portion voltage accounting that internal resistance is consumed is few, therefore when open circuit
Voltage when leveling off to electromotive force, that is, prove battery be will be at full charge, to prevent over-charging of battery, described overcharge refers to battery
In charging, after full state is reached, continue to charge.Such way may cause inner pressure of battery rise, cell deformation, leakage
Situations such as liquid, occurs, and the performance of battery also can be significantly reduced and damaged.Prevent from overcharging using between open-circuit voltage and electromotive force
Difference, its difference is mainly the voltage that the internal resistance of cell is consumed, the internal resistance of cell may variation with temperature and change,
Therefore reserved part is judged in the form of numerical intervals.
When the difference of open-circuit voltage and the electromotive force of battery is more than first threshold, that is, prove that present battery fills apart from electricity
Full state also has a stage, then battery remains able to can perform with the high current form charging of grading current, mobile terminal
The step of obtaining grading current.
Step S60, when the difference of open-circuit voltage and the electromotive force of battery is less than or equal to first threshold, is obtained default
Pre-set buffer electric current in battery specifications table, and the current charging current of battery is adjusted to pre-set buffer electric current.
When the difference of open-circuit voltage and the electromotive force of battery is less than first threshold, that is, prove that present battery comes into electricity
In the coda stage of pond charging, battery electric quantity is that will be filled with, it is assumed that now still charged with default grading current before, then battery
Easily produce and overcharge, easily cause certain potential safety hazard.Therefore, now need to make using a comparatively safe buffer current
Enter row buffering for the low current of battery.The pre-set buffer electric current can refer to the specification of battery, be filled using trickle the most stable
Power mode, the first threshold should not use larger numerical value, prevent that the charging interval of follow-up pre-set buffer electric current is long,
Too small numerical value should not be used, it is to avoid appearance causes current switching to cause showing for battery fast heating not in time because gap is too small
As.Get after pre-set buffer electric current, charging current can be adjusted to pre-set buffer electric current by battery.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole

Step S70, obtains the real time temperature of battery, and judges whether real time temperature is more than Second Threshold；
The real time temperature of battery is the embodiment of battery present charge state.The real time temperature of acquisition for mobile terminal battery, it is real
Shi Wendu is too high, it was demonstrated that the charging current in battery charging process is excessive, causes caloric value to increase considerably.Accordingly, it would be desirable to first
The real time temperature of battery is got, and the real time temperature is judged.
Step S80, when real time temperature is more than Second Threshold, preset security electric current is obtained based on open-circuit voltage, and by electricity
The current charging current in pond is adjusted to preset security electric current.
If real time temperature is more than Second Threshold, proves that current battery needs cooling, otherwise can not ensure the peace of battery
Entirely.Therefore, compared to the lifting of charge efficiency, charging safety with greater need for overriding concern.
Be preset with preset security electric current in battery specifications list, the preset security electric current refer to battery temperature compared with
Allow the charging current used in the case of height.The preset security electric current is the production business men of mobile terminal according to the electricity of battery
The reference data that pond specification has been looked after and guided in advance.The electric current of battery is excessive to cause temperature to rise to a certain extent, therefore to battery
Cooling processing is carried out, it is necessary to adjust the charging current of battery.Charging current is adjusted to preset security electric current, can significantly be dropped
The real time temperature of low battery.
Further, on the basis of mobile terminal staged charging method first embodiment of the present invention, propose mobile whole
The embodiment of staged charging method the 8th is held, the difference between the 8th embodiment and first embodiment is, the battery
Resistance include the internal resistance of cell and line resistance.
The resistance of battery is except the resistance of inside battery, in addition to the line resistance that connection line material is produced.Line electricity
Hinder same open-circuit voltage and produce certain influence.Therefore, when calculating the open-circuit voltage of battery, it is necessary to which line resistance is also same
Sample is counted, to avoid causing open-circuit voltage calculating incorrect because ignoring line resistance.For example, circuit resistance in itself and
Cause the change of line resistance after temperature rise, while having influence on the change of open-circuit voltage.Line resistance can pass through mobile terminal
It is parameter-embedded be determined, be included in the resistance value of battery；Can also as resistance float value, what it was calculated opens
