Being implemented in the form of software for choosing, can also be implemented, within that scope of the present invention on hardware certainly.
Concrete analysis explanation is carried out below.
In the present embodiment, it will be described from the angle of battery charge controller, which can specifically collect
At in terminal, such as mobile phone, tablet computer, palm PC (PDA, Personal Digital Assistant) etc..
Referring to Fig. 1, Fig. 1 is the flow diagram of charge control method provided in an embodiment of the present invention.Specifically, should
Method includes:
In step s101, when detecting that terminal is charged, the electrical parameter in preset time period is obtained.
It should be noted that user by universal serial bus (Universal serial Bus, USB) by terminal with
When charging end connects, as detect that terminal is in charging.
Wherein, which may include that the changing value of residual power percentage and terminal are electric within a preset period of time
The charge value that pond obtains.The value of the residual power percentage is terminal power show value, generally hundred-mark system, and 100 be full electric shape
State, 0 are no state of charge.The value of the residual power percentage generally passes through the voltage value for obtaining end cell, each voltage value
The value of corresponding residual power percentage, then extrapolates the value of corresponding residual power percentage according to voltage value, when will be default
Between section end point residual power percentage value subtract preset time period start time point residual power percentage value, obtain
Out in preset time period residual power percentage changing value.The charge value that the end cell obtains can be obtained by charging chip
It takes, for the charge value for flowing through end cell, unit is milliampere hour (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 battery.Anode (cathode) is by non-
The lithium compound of metalline is constituted, and is connected with the cathode (anode) consisting of carbon.When charging, lithium ion (or charge atom)
It is forced to move to anode from cathode under external voltage effect, is then stored in anode.When electric discharge, these storage lithiums from
Son flows back into cathode again and forms electric current, provides energy for terminal.And as the cathode of end cell is in thousands of changes
Learn process gradually rotten in variation.The lithium compound for constituting cathode constantly absorbs and releases lithium ion in chemical reaction,
Change also occurs for the structure of itself simultaneously, causes the exchange of ion to become difficult, at this moment the actual capacity of end cell is also got over
Come lower.
Wherein, which includes actual capacity and rated capacity (i.e. factory capacitance), which is eventually
When the voltage of end cell reaches highest blanking voltage under the battery current environment of end, i.e. capacitance of mobile phone when fully charged should
Actual capacity can be reduced with the aging of battery and the variation of environment temperature.And the predetermined capacitance is end cell factory
When, that is, optimum state under it is fully charged when capacitance.The rated capacity value of every piece of end cell is all determining when leaving the factory.
For example, when one piece of intact end cell is charged to a hundred percent from 0 percent under normal circumstances, what end cell obtained
Charge value is actual capacity, and actual capacity is equal to rated capacity at this time；When the end cell of one piece of aging is from percent
Zero when being charged to a hundred percent, and charge value, that is, actual capacity that end cell obtains can be less than rated capacity.
In certain possible embodiment, it is assumed that the electricity percentage of preset time period starting point is D1, preset time
The electricity percentage of section end point is D0, and the charge value that end cell obtains 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 obtains in preset time period is divided by electricity remaining in preset time period
The ratio for measuring the changing value of percentage is actual capacity.
Based on this, the existing mode main lift charging current for promoting charging rate, so that the electricity of end cell
Quickly promoted, and in the case where end cell has certain aging or too low environment temperature, the internal resistance meeting of end cell
Becoming very big, can become very big along with the internal resistance of end cell, the actual capacity of terminal can become very little, and in end cell
Actual capacity when becoming very little, still charged using high current, end cell can fast heating, accelerating terminal battery it is old
Change, even results in battery explosion, bring great loss 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 (factory capacitance) can be calculated
Value, obtains capacitance percentage.The capacitance percentage is higher, then reflects that the performance of end cell is better, the capacitance percentage
Than lower, then reflect that the temperature for the environment that the performance of end cell is poorer, or currently charges is lower.It at this time can be by default
Charging current table corresponds to different charging currents according to capacitance percentage, it is contemplated that capacitance percentage is higher i.e.
The performance of battery is better, indicates that the ability for the charging current value that end cell can receive is stronger, corresponding charging current value
It is 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, indicates terminal
The ability for the charging current value that battery can receive is weaker, and corresponding charging current value is also lower.Based on the charging current table
Matching relationship, matches the current corresponding charging current value of capacitance percentage, which is to be suitble to present terminal
The charging current value of cell safety charging.
Illustrate current end cell when obtaining the capacitance percentage lower than certain secure threshold based on this
Degree of aging already exceed secure threshold or current environment temperature lower than safe temperature, then directly disconnect and terminal filled
Electricity, to guarantee 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, it can directly pass through the charging current value obtained in step S103 to terminal
Charging current is adjusted, and into after crossing and adjust, the charging current value of terminal is the charging current of most suitable present case, can be with
It reduces the aging of end cell and guarantees the safety of end cell.In alternatively possible embodiment, transmission can be passed through
Charge prompting information charges to end cell using the charging current value to prompt the user whether, user can be flexible
Selection still charges to end cell with maximum charging current, in urgent need in use, can need not adjust to reach quick
The purpose of charging.
It can be seen from the above, a kind of charge control method provided in this embodiment, when being preset by obtaining in terminal charge
Between electrical parameter in section calculate the actual capacity of end cell, suitable charging current value is matched according to the actual capacity
It charges to end cell, the aging speed of end cell can be reduced, and promote the safety in utilization of end cell.
Citing, is described in further detail by the method according to described in above-described embodiment below.
Referring to Fig. 2, Fig. 2 is another flow diagram of charge control method provided in an embodiment of the present invention.
Specifically, this method comprises:
In step s 201, when detecting that terminal is charged, the residual power percentage in preset time period is obtained
Changing value and end cell obtain charge value.
Wherein, the value of the residual power percentage is terminal power show value, generally hundred-mark system, 100 be full power state,
0 is no state of charge.The value of the residual power percentage generally passes through the voltage value for first obtaining end cell, the end cell
Each voltage value corresponds to the value of residual power percentage.
1 terminal battery voltage counterpart terminal voltameter of table
| Residual power percentage | Cell voltage V |
| 100 | 4.2 |
| 90 | 4.08 |
| 80 | 4 |
| 70 | 3.93 |
| 60 | 3.87 |
| 50 | 3.82 |
| 40 | 3.79 |
| 30 | 3.77 |
| 20 | 3.73 |
| 10 | 3.68 |
| 0 | 2.5 |
As shown in table 1, the corresponding residual power percentage of each cell voltage has corresponding relationship, can be when will be default
Between section end point residual power percentage value subtract preset time period start time point residual power percentage value, obtain
Out in preset time period residual power percentage changing value.For example, be 2.5V in preset time period starting point cell voltage, it is right
The value for the residual power percentage answered is 0, is 2.95V, corresponding remaining capacity hundred in preset time period end point cell voltage
The value for dividing ratio is 5, then show that the changing value of residual power percentage in preset time period is 5, the electricity which obtains
Magnitude can be obtained by charging chip, and for the charge value for flowing through end cell, unit is milliampere hour (mAh).
In step S202, the ratio of the charge value of end cell acquisition and the changing value of the residual power percentage is calculated
Value, obtains calculated result, and the calculated result is determined as to the actual capacity of end cell.
Wherein, according to the charge value for flowing through end cell that charging chip is got in preset time period in step S201,
With the ratio of the changing value of the residual power percentage in preset time period, the actual capacity of end cell is found out.For example, when stream
The charge value for crossing end cell is 100mAh, and the changing value of residual power percentage is 5 in preset time period, then with 100mAh
Determine that the actual capacity of end cell is 2000mAh divided by 5 percent.
It should be noted that the actual capacity is different from rated capacity (factory capacitance), which goes out for producer
In the optimal attainable maximum capacitance of terminal under environment battery when factory's end cell, actual capacity is with rated capacity at this time
It is consistent, but with the Reusability of end cell, the lithium compound of cathode constantly absorbs and releases in chemical reaction
Lithium ion, while change also occurs for the structure of itself, cause the exchange of ion become difficult or electrolyte it is fewer and fewer,
Cause the actual capacity of end cell that can become lower and lower.
In step S203, according to the ratio of the rated capacity of actual capacity and end cell, current capacitance is obtained
Percentage.
Wherein, the actual capacity obtained in step S202 is obtained divided by the rated capacity (factory capacitance) of end cell
Current capacitance percentage out.The capacitance percentage is higher, then reflects that the performance of end cell is better, the capacitance percentage
Than lower, then reflect that the temperature for the environment that the performance of end cell is poorer, or currently charges is lower.It is contemplated that electric
The performance of the higher i.e. battery of volume percent is better, indicates that the ability for the charging current value that end cell can receive is stronger, phase
The charging current value answered 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, indicates that the ability for the charging current value that end cell can receive is weaker, corresponding charging current value is also lower.
Based on this, the existing mode main lift charging current for promoting charging rate, so that the electricity of end cell
Quickly promoted, and in the case where end cell has certain aging or too low environment temperature, the internal resistance meeting of end cell
Becoming very big, can become very big along with the internal resistance of end cell, the actual capacity of terminal can become very little, and in end cell
Actual capacity when becoming very little, still charged at this time using high current, end cell can fast heating, will lead to acceleration eventually
The aging for holding battery, even results in battery explosion, brings great loss to user.
In step S204, whether detection capacitance percentage is lower than default secure threshold.
Wherein, if it is detected that capacitance percentage is lower than default secure threshold, illustrate the aging of current end cell
Very serious or current environment temperature is too low for degree, executes step S205；If it is detected that capacitance percentage is not less than
Default secure threshold, thens follow the steps S206.
In step S205, stopping charges to terminal.
In certain possible embodiment, when detecting that capacitance percentage is lower than default secure threshold, explanation is worked as
The internal resistance of preceding end cell is very big, at this point, will lead to end cell if continuing to charge to end cell and generate a large amount of heat
Amount, or even explode, certain threat is brought to user security, presets secure threshold when detecting that capacitance percentage is lower than
When, terminal executes at once stops charging operations, and can also send safety instruction information, to prompt 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 obtained.
It wherein, may include the corresponding charging current value of capacitance percentage in the preset charged ammeter.
2 capacity ratio of table corresponds to charging current value table
| Capacitance percentage | Charging current value |
| 90-100 | 4A |
| 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, be easy it is found out that, capacitor
It measures that percentage-proportion interval is lower, and corresponding charging current value is smaller, when capacitance percentage is less than 40, then illustrates the Terminal Capacitance amount
Percentage terminates charging already below default secure threshold.
For example, the rated capacity of the battery of terminal is 2500mAh when actual capacity is 2000mAh, at this point, obtain
Capacitance percentage is 80, according to table 2, show that the corresponding charging current value for being most suitable for the charging is 3.5A.
In step S207, according to charging current value, the current charging current of terminal is adjusted.
It should be noted that usually in the night's rest time of user, such as between 12 points to 7 points of morning of morning, it uses
Family is in resting state, and terminal will do it screen locking, then terminal need not just use high current to carry out fast charge mode, to avoid height
Electric current damages end cell.
In certain possible embodiment, this is adjusted the current charging current of terminal according to charging current value
Whether the current time that the terminal can also be detected before is in default evening hours section, if it is detected that at the current time of terminal
In default evening hours section, then enters night charge mode, obtain pre-set current value under the night charge mode, it is pre- according to this
If current value is adjusted the current charging current of terminal；If it is detected that when the current time of the terminal is not at default night
Between section, then trigger execution send charge prompting information the step of.
For example, the default evening hours section can be set to 00:00 to 07:00, it can also be customized by the user input, if
It detects that the current time of terminal is in default evening hours section, illustrates that terminal need not currently use high current to carry out fast mold filling
Formula then enters night charge mode, pre-set current value is obtained under the night charge mode, according to the pre-set current value to terminal
Current charging current the step of being adjusted, which is low current value, which is at least more than terminal
The current value of system electricity consumption value；If it is detected that the current time of the terminal is not at default evening hours section, sends charging and mention
Show information, which charges to end cell with the charging current value to prompt the user whether.User exists
After receiving the charge prompting information, if can choose and determine using charging electricity in the case where not being badly in need of the scene of terminal charge
Flow valuve charges to end cell, if under the scene for being badly in need of terminal charge, if user needs quick charge to go out, then
It can refuse to reduce the charging current value.
In certain possible embodiment, adjustment charging current can be terminal transmission regulating command to charger, by
Charger adjusts the charging current value to regulating command instruction to charge to terminal.
In order to preferably describe the embodiment of the present invention, it is described in detail with terminal charge shown in Fig. 3 prompt schematic diagram:

Amount show value is that testing mobile phone battery current voltage obtains, the corresponding mobile phone electricity show value of each voltage is fixed.And
The charge value that Mobile phone battery chip obtains in preset time period is 100mAh, then can be by charge value 100mAh divided by surplus
The changing value 0.05 of remaining electricity percentage obtains current actual capacity 2000mAh.
Wherein, battery of mobile phone further includes rated capacity (factory capacitance), which is changeless, and is only had
Battery of mobile phone it is intact and just in use, the actual capacity just can be equal to the rated capacity, battery of mobile phone can with use by
The internal resistance of gradually aging, terminal can become larger, lower and lower so as to cause the actual capacity of battery of mobile phone, by the actual capacity divided by volume
Constant volume, the capacity ratio of available battery of mobile phone, and the capacity ratio can measure battery performance, when the capacity ratio is higher, then
Illustrate that the performance of battery is better, when the capacity ratio is lower, then illustrates that the performance of battery is lower, degree of aging is bigger, the electricity of charging
Flow valuve is not answered excessive.Assuming that show that the capacity ratio is 0.8 when the rated capacity of mobile phone is 2500mAh, it can be according to capacity ratio
With preset charged ammeter, the charging current value such as 3A that corresponding suitable battery of mobile phone currently charges is obtained.It sends as shown in Figure 3
Prompt information is prompted the user whether to adjust to adaptation electric current and be charged to terminal, and when the user clicks when "Yes", mobile phone can will fill
The charging current value at electric end is adjusted to 3A, when the user clicks when "No", is still charged with former charging current value to mobile phone.If figure
After prompt information shown in 3 occurs 10 seconds, the operational order of user is not received yet, then directly executing the charging of charging end
Current value is adjusted to 3A.
In certain possible embodiment, when the capacity ratio got is lower than certain secure threshold, illustrate mobile phone
Cell degradation degree is very serious, stops immediately to the charging of battery of mobile phone.
For the detailed description embodiment of the present invention, it is described in detail with terminal night shown in Fig. 4 charging schematic diagram:
At night, in 00:00 to the period between 07:00, user is in resting state, and terminal will do it screen locking, then terminal
Need not just high current be used to carry out fast charge mode.As shown in figure 4, it is 00:48 that terminal, which gets current display time, in pre-
If evening hours section 00:00 is between 07:00, user is in resting state at this time, if terminal is carried out fastly using high current always
Mold filling formula, then can increasing terminal battery aging, in order to avoid such case, terminal can enter night charge mode, at this
Pre-set current value is obtained under night charge mode and obtains pre-set current value, this pre-set current value is the height electricity relative to fast charge mode
Small current value for stream charges to terminal with this low current value, then the old of end cell can preferably be prevented
