Concrete analysis explanation is below carried out.
In the present embodiment, will be described from the angle of battery charge controller, the battery charge controller can specifically collect Into in terminal, such as mobile phone, panel computer, palm PC (PDA, Personal Digital Assistant) etc..
Fig. 1 is referred to, Fig. 1 is the schematic flow sheet of charge control method provided in an embodiment of the present invention.Specifically, should Method includes:
In step S101, when detecting terminal and being charged, the electrical parameter in preset time period is obtained.
It should be noted that user by USB (Universal serial Bus, USB) by terminal with When charging end connects, terminal is as detected in charging.
Wherein, the electrical parameter can be included in the changing value of dump energy percentage and terminal electricity in preset time period The charge value that pond obtains.The value of the dump energy percentage is terminal power show value, generally hundred-mark system, and 100 are full electricity shape State, 0 are without state of charge.The value of the dump energy percentage is typically by the magnitude of voltage of acquisition end cell, each magnitude of voltage The value of corresponding dump energy percentage, then extrapolates the value of corresponding dump energy percentage, when will be default according to magnitude of voltage Between section end point dump energy percentage value deduct preset time period start time point dump energy percentage value, obtain Go out the changing value of dump energy percentage in preset time period.The charge value that the end cell is obtained can be obtained by charging chip Take, for flowing through the charge value of end cell, unit is MAH (mAh).
In step s 102, the actual capacity of end cell is calculated based on the electrical parameter.
It should be noted that the end cell can refer to lithium battery or other similar batteries.Anode (negative pole) is by non- The lithium compound of metalline is constituted, and is connected with the negative electrode (positive pole) being made up of carbon.During charging, lithium ion (or charge atom) Under external voltage effect be forced positive pole to be moved to from negative pole, then store in positive pole.During electric discharge, these storage lithium from Son is back to negative pole again and forms electric current, provides energy for terminal.And as the negative pole of end cell is in thousands of secondary changes Learn the process gradually gone bad in change.The lithium compound for constituting negative pole constantly absorbs in chemical reaction and discharges lithium ion, The structure of itself also occurs to change simultaneously, causes the exchange of ion to become difficult, and at this moment the actual capacity of end cell is also got over Come lower.
Wherein, the end cell includes actual capacity and rated capacity (capacitance of dispatching from the factory), and the actual capacity is for eventually When under end-cell current environment, the voltage of end cell reaches highest blanking voltage, i.e. capacitance of mobile phone when fully charged should Actual capacity can reduce with the change of the aging and environment temperature of battery.And the predetermined capacitance is dispatched from the factory for end cell When capacitance when being fully charged under optimum state.The rated capacity value of every piece of end cell is all to determine when dispatching from the factory. Such as, when one piece of intact end cell is charged to a hundred per cent from 0 percent under normal circumstances, end cell is obtained Charge value is actual capacity, and now actual capacity is equal to rated capacity;When one piece of aging end cell is from percent Zero when being charged to a hundred per cent, and the charge value that end cell is obtained is that actual capacity can be less than rated capacity.
In certain possible embodiment, it is assumed that the electricity percentage of preset time period starting point be D1, Preset Time The electricity percentage of section end point is D0, and the charge value that end cell is obtained in the preset time period is CC, and actual capacity is FCC, then the electricity percentage D0=D1+CC/FCC of preset time period end point, carries out being derived from reality according to the formula Capacity FCC=CC/ (D0-D1), i.e., the charge value that end cell is obtained in preset time period is divided by remaining electricity in preset time period The ratio of the changing value of amount percentage is actual capacity.
This is based on, the existing mode main lift charging current for lifting charging rate, so that the electricity of end cell Quickly lifted, and had in the case that necessarily aging or environment temperature is too low in end cell, the internal resistance meeting of end cell Become very big, the internal resistance along with end cell can become very big, and the actual capacity of terminal can become very little, and in end cell Actual capacity when becoming very little, be still charged using high current, end cell can fast heating, accelerating terminal battery old Change, even result in battery explosion, greatly loss is brought to user.
In step s 103, according to the actual capacity, corresponding charging current value is matched.
In certain possible embodiment, the ratio of the actual capacity and rated capacity (capacitance of dispatching from the factory) can be calculated Value, draws capacitance percentage.The capacitance percentage is higher, then the performance of reflection end cell is better, the capacitance percentage Than lower, then reflect that the performance of end cell is poorer, or the temperature of the current environment for charging is lower.Can now pass through default Charging current table, according to the corresponding different charging current of capacitance percentage, it is contemplated that capacitance percentage is higher i.e. The performance of battery is better, represents that the ability of the charging current value that end cell can be received is stronger, corresponding charging current value Higher.The charging ambient temperature that the degree of aging of the lower i.e. battery of capacitance percentage is stronger or current is lower, represents terminal The ability of the charging current value that battery can be received is weaker, and corresponding charging current value is also lower.Based on the charging current table Matching relationship, matches the corresponding charging current value of current capacitance percentage, and the charging current value is suitable present terminal The charging current value that cell safety charges.
This is based on, when showing that the capacitance percentage is less than certain secure threshold, that is, current end cell is described Degree of aging already exceed secure threshold or current environment temperature less than safe temperature, then directly disconnect and terminal filled Electricity, to ensure the safety of user.
In step S104, according to the charging current value, the current charging current of terminal is adjusted.
In a kind of possible embodiment, can directly pass through the charging current value drawn in step S103 to terminal Charging current is adjusted, and after adjustment was entered, the charging current value of terminal is the charging current of most suitable present case, can be with Reduce the aging of end cell and ensure the safety of end cell.In alternatively possible embodiment, can pass through to send Charge prompting information, in order to prompt the user whether to be charged end cell using the charging current value, user can be flexible Select, when being badly in need of using, it may not be necessary to adjust, still end cell is charged with maximum charging current, quick to reach The purpose of charging.
From the foregoing, a kind of charge control method that the present embodiment is provided, when being preset by terminal charge, obtaining Between electrical parameter in section calculate the actual capacity of end cell, suitable charging current value is matched according to the actual capacity End cell is charged, the aging speed of end cell, and the safety in utilization for lifting end cell can be reduced.
Citing is described in further detail by method according to described by above-described embodiment below.
Fig. 2 is referred to, Fig. 2 is another schematic flow sheet of charge control method provided in an embodiment of the present invention.
Specifically, the method includes:
In step s 201, when detecting terminal and being charged, the dump energy percentage in preset time period is obtained Changing value and end cell obtain charge value.
Wherein, the value of the dump energy percentage is terminal power show value, generally hundred-mark system, 100 be full power state, 0 is without state of charge.The value of the dump energy percentage typically passes through the magnitude of voltage for first obtaining end cell, the end cell The value of the corresponding dump energy percentage of each magnitude of voltage.

As shown in table 1, the corresponding dump energy percentage of each cell voltage has corresponding relation, can be when will be default Between section end point dump energy percentage value deduct preset time period start time point dump energy percentage value, obtain Go out the changing value of dump energy percentage in preset time period.Such as, preset time period starting point cell voltage be 2.5V, right The value of the dump energy percentage that answers be 0, preset time period end point cell voltage be 2.95V, corresponding dump energy hundred The value of point ratio is 5, then the changing value for drawing dump energy percentage in preset time period is 5, the electricity that the end cell is obtained Value can be obtained by charging chip, and for flowing through the charge value of end cell, unit is MAH (mAh).
In step S202, the charge value of end cell acquisition and the ratio of the changing value of the dump energy percentage is calculated Value, obtains result of calculation, and the result of calculation is defined as the actual capacity of end cell.
Wherein, the charge value for flowing through end cell for being got according to charging chip in preset time period in step S201, With the ratio of the changing value of the dump energy percentage in preset time period, the actual capacity of end cell is obtained.Such as, work as stream The charge value for crossing end cell is 100mAh, and in preset time period, the changing value of dump energy percentage is 5, then with 100mAh Divided by 5 percent determine end cell actual capacity be 2000mAh.
It should be noted that the actual capacity is different from rated capacity (capacitance of dispatching from the factory), the rated capacity goes out for producer The maximum capacitance that end cell can reach under optimal environment during factory's end cell, now actual capacity with rated capacity be Consistent, but the Reusability with end cell, lithium compound constantly absorption and release in chemical reaction of negative pole Lithium ion, while the structure of itself also occurs to change, causes the exchange of ion to become the fewer and feweri of difficult or electrolyte, Cause the actual capacity of end cell become more and more lower.
In step S203, according to actual capacity and the ratio of the rated capacity of end cell, current capacitance is drawn Percentage.
Wherein, the actual capacity drawn in step S202 is obtained divided by the rated capacity (capacitance of dispatching from the factory) of end cell Go out current capacitance percentage.The capacitance percentage is higher, then the performance of reflection end cell is better, the capacitance percentage Than lower, then reflect that the performance of end cell is poorer, or the temperature of the current environment for charging is lower.It is contemplated that electric The performance of the higher i.e. battery of volume percent is better, represents that the ability of the charging current value that end cell can be received is stronger, phase The charging current value that answers is also higher.The stronger or current charging environment temperature of the degree of aging of the lower i.e. battery of capacitance percentage Degree is lower, represents that the ability of the charging current value that end cell can be received is weaker, and corresponding charging current value is also lower.
This is based on, the existing mode main lift charging current for lifting charging rate, so that the electricity of end cell Quickly lifted, and had in the case that necessarily aging or environment temperature is too low in end cell, the internal resistance meeting of end cell Become very big, the internal resistance along with end cell can become very big, and the actual capacity of terminal can become very little, and in end cell Actual capacity when becoming very little, be now still charged using high current, end cell can fast heating, will cause to accelerate eventually End-cell aging, even result in battery explosion, bring greatly loss to user.
In step S204, whether detection capacitance percentage is less than preset security threshold value.
Wherein, if detecting, capacitance percentage, less than preset security threshold value, illustrates the aging of current end cell The temperature of degree very serious or current environment is too low, execution step S205;If detecting, capacitance percentage is not less than Preset security threshold value, then execution step S206.
In step S205, stop being charged terminal.
In certain possible embodiment, when detecting that capacitance percentage is less than preset security threshold value, illustrate to work as The internal resistance of front end cell is very big, now, if continuing to charge to end cell, end cell can be caused to produce substantial amounts of heat Amount, or even explodes, and brings certain threat to user security, when detecting capacitance percentage less than preset security threshold value When, terminal is executed at once and stops charging operations, and can also send safety instruction information, to point out the current charging operations of user to deposit In danger.
In step S206, by capacitance percentage match preset charged ammeter, corresponding charging current value is drawn.
Wherein, the corresponding charging current value of capacitance percentage can be included in the preset charged ammeter.
The corresponding charging current value table of 2 capacity ratio of table
Capacitance percentage Charging current value

80-90 3.5A
70-80 3A
60-70 2.5A
50-60 2A
40-50 1.5A
As shown in table 2, each capacitance percentage-proportion interval has corresponding charging current value, easily it is found out that, electric capacity Amount percentage-proportion interval is lower, and corresponding charging current value is less, when capacitance percentage is less than 40, then the Terminal Capacitance amount is described Percentage is already below preset security threshold value, complete charge.
Such as, when actual capacity is 2000mAh, the rated capacity of the battery of terminal is 2500mAh, now, draws Capacitance percentage is 80, according to table 2, show that the charging current value for being correspondingly best suitable for the charging is 3.5A.
In step S207, according to charging current value, the current charging current of terminal is adjusted.
