In a preferred embodiment, a kind of charge control method is provided, as shown in Figure 1, process can be such that
101, it obtains battery and is in constant voltage values required when the constant voltage charging stage.
With reference to Fig. 2, the stage to charge the battery in the present embodiment may include: pre-charging stage, constant current charging rank
Section, constant voltage charging stage etc..
Wherein, pre-charging stage, also referred to as trickle charge stage, trickle charge are used to first carry out the battery to discharge completely
Preliminary filling (restorative charging).Trickle charge is generally used when cell voltage is lower than some voltage value such as when 3V or so, trickle fills
Electric current is that 1/10th i.e. 0.1c of constant-current charge electric current (is illustrated with constant charge current for 1A, then trickle-charge current is
100mA)。
Constant current charging phase namely constant-current charging phase, when cell voltage rises to trickle charge threshold value or more,
It improves charging current and carries out constant-current charge.The electric current of constant-current charge is in 0.2C between 1.0C.Cell voltage is with constant-current charge
Process is stepped up, this voltage that general single battery is set is 3.0-4.2V.
Constant voltage charging stage, i.e. constant-voltage charge --- when cell voltage rises to 4.2V, constant-current charge terminates, and opens
Beginning constant voltage charging phase.Electric current according to the degree of saturation of battery core, with the continuation charging current of charging process by maximum value slowly
It reduces, when being reduced to 0.01C, it is believed that charging termination.(C is with a kind of representation method of battery nominal capacity control electric current, such as
Battery is the capacity of 1000mAh, and 1C is exactly charging current 1000mA.).
The present embodiment, in charging, constant voltage values needed for available battery is in the constant voltage charging stage, such as
4.2V.Wherein, constant voltage values needed for the constant voltage charging stage can be set according to actual needs, such as 4.3V.
102, corresponding fixed voltage value is obtained according to the constant voltage.
Wherein, fixed voltage value is greater than constant voltage values, for example, constant voltage values are 4.2V value, which can
Think 5v etc..
The fixed voltage value is that module to be charged needs charging voltage to be loaded.Therefore, which can be based on
The resistance value of adjustable resistance obtains in module to be charged, which can be the maximum or minimum resistance value of adjustable resistance.Namely step
Suddenly " obtaining corresponding fixed voltage value according to the constant voltage " may include:
Obtain the maximum value of adjustable resistance or minimum resistance value in module to be charged；
According to the constant voltage values and (maximum value of adjustable resistance or minimum resistance value), fixed voltage value is calculated.
For example, for save electric energy, the fixed voltage value be not easy to be arranged it is excessive, therefore, the minimum internal resistance of available battery
R passes through constant voltage values VIt is constantWith minimum internal resistance R, the maximum charging current Imax of battery, the Imax=V are calculatedIt is constant/ R, so
Afterwards, the maximum voltage Vmax of adjustable resistance during the charging process is calculated, the Vmax=Imax*Rmax, the Rmax are adjustable resistance
Maximum resistance value, then, fixed voltage value VIt is fixed=VIt is constant+Vmax。
103, the corresponding charging voltage of module loading to be charged is given according to the fixed voltage value, which includes phase
Mutual concatenated battery and adjustable resistance.
With reference to Fig. 3, the present embodiment module to be charged may include battery and adjustable resistance, and the battery and adjustable resistance are mutual
Series connection.Battery charge controller can record corresponding electricity at the module both ends to be charged according to the fixed voltage value in the present embodiment
V is pressed, to charge the battery.
Wherein, adjustable resistance can be single adjustable resistance, or the adjustable resistance being made of multiple adjustable resistances
Unit etc. can specifically be set according to actual needs.
104, in the process of charging the battery, the resistance value of the adjustable resistance is adjusted, so that the battery is worked as
Preceding charging parameter value meets the parameter value requirement of locating charging stage.
For example, in the process of charging the battery, battery charge controller sends resistance value regulating command to adjustable resistance, so as to
Current resistance value is adjusted to corresponding target resistance value according to the order by adjustable resistance.
The current charging parameter value of battery may include charging voltage value, charging current value etc..
Since in order to ensure charging safety, battery charging was needed by multiple charging stages, such as precharge, constant-current charge rank
Section etc., requirement of each charging stage to charge parameter such as voltage, electric current be not identical, for example, the charging electricity of pre-charging stage
Stream is 100mA, the charging current of constant-current charging phase is 1000mA, the charging voltage of constant voltage charging phase is 4.2V, therefore,
The different charging stages needs to carry out different adjustings to the resistance value of adjustable resistance, so that current charge parameter reaches corresponding
Charge parameter requirement.Specifically, step " resistance value of the adjustable resistance is adjusted " may include:
Determine the charging stage that the battery is presently in；
It obtains the current resistance value of the battery and the battery is presently in charging stage corresponding preset charged parameter
Value；
According to the current resistance value of battery and the preset charged parameter value, the resistance value of the adjustable resistance is adjusted, with
So that current charging parameter value is equal to the preset charged parameter value.
Wherein, preset charged parameter value may include preset charged electric current, preset charge voltage etc..For example, being pre-charged
In the stage, which is the first preset charged current value, in constant current charging phase, the preset charged parameter value
It can be the second preset charged current value (wherein, the second preset charged electric current is greater than the first preset charged current value), constant
The voltage charging stage, the preset charged parameter value can be preset charge voltage value, etc..
The present embodiment can real-time monitoring battery during the charging process voltage, determine that battery is presently according to the voltage
Charging stage, for example, when the voltage of battery be greater than pre-charge voltage threshold value when then determine be in constant current charging phase, when
When the voltage of voltage is greater than constant-voltage charge voltage threshold, it is determined that be in the constant voltage charging stage.The present embodiment can be with root
The charging stage that battery is presently in is determined according to the duration of charging.Specifically, step " determines the charging that the battery is presently in
Stage " may include:
Obtain the current accumulative charging duration of the battery；
Add up the charging stage that charging duration determines that the battery is presently according to this.
Optionally, it is contemplated that the internal resistance of battery constantly becomes smaller with the duration of charging, therefore, it is also desirable to can be changed
The resistance change rate of resistance can be equal to the resistance change rate of the internal resistance of cell.Namely step " according to the current resistance value of battery and
The preset charged parameter value, is adjusted the resistance value of the adjustable resistance, so that current charging parameter value is preset equal to this and filled
Electrical parameter values " may include:
The target resistance value of adjustable resistance is determined according to the current resistance value of battery and the preset charged parameter value；
The resistance value of the adjustable resistance is adjusted to target resistance value, and keeps the resistance change rate of variable resistance in the positive direction
Equal to the resistance change rate of the internal resistance of cell in a negative direction, so that the current charging parameter value is equal to preset charged parameter value.
Wherein, which is the variable quantity of resistance in the unit time.The positive direction is the side that resistance value becomes larger
To negative direction is the direction that resistance value becomes smaller.
The resistance adjustment process of different phase is described below:
(1), when preset charged parameter value includes preset charged current value.
Step " according to the current resistance value of battery and the preset charged parameter value, is adjusted the resistance value of the adjustable resistance
Save, so that current charging parameter value is equal to the preset charged parameter value " may include:
First resistor value is obtained according to the fixed voltage value and the preset charged current value；
According to the first resistor value and the current resistance value of the battery, second resistance value needed for obtaining the adjustable resistance；
The resistance value of the adjustable resistance is adjusted to the second resistance value, so that the present charging current value is equal to preset charged
Current value.
For example, obtaining the locating precharge of battery current resistance value R0 and battery when battery is in pre-charging stage
The first preset charged current value I ' in stage, then, according to the current resistance value R0 of battery and the first preset charged electric current
The resistance value of adjustable resistance is adjusted in value I ', so that present charging current value I is equal to the first preset charged current value
I'.Specifically, first resistor value R1 is obtained according to fixed voltage value V and preset charged current value I ', i.e., module to be charged it is total
Resistance value, the R1=V/I ', then, needed for calculating adjustable resistance according to first resistor value R1 and battery current resistance value R
Second resistance value R2=R1-R, later adjusts the resistance value of adjustable resistance to R2.
The internal resistance of general battery is as charging duration is ever-reduced, therefore in order to guarantee to protect in the corresponding charging stage
It holds under preset charged levels of current, it is also necessary to which the resistance for allowing the resistance change rate of variable resistance to be equal to the internal resistance of cell becomes
Rate.That is, the resistance value of the adjustable resistance " is adjusted to the second resistance value, so that the present charging current value is equal to by step
Preset charged current value " may include:
The resistance value of the adjustable resistance is adjusted to the second resistance value, and keeps the resistance of variable resistance in the positive direction
Change rate is equal to the resistance change rate of the internal resistance of cell in a negative direction, so that the present charging current value is equal to preset charged electric current
Value.Wherein, which is the variable quantity of resistance in the unit time.The positive direction is the direction that resistance value becomes larger, and is born
Direction is the direction that resistance value becomes smaller.
For example, generally in pre-charging stage, that is, initial charging phase, the internal resistance of cell is larger, and the preset charged electricity in the stage
Flow valuve is smaller, and in pre-charging stage, which will from large to small, therefore, in order to guarantee that charging current maintains the rank
In the preset charged levels of current of Duan Yaoqiu, the resistance value of adjustable resistance, the resistance change rate of variable resistance can be constantly increasing
The resistance change rate of the internal resistance of cell can be equal to, can guarantee that being equal to first in the current charging current of pre-charging stage presets in this way
Charging current value.
Equally, for example, when battery is in constant current charging phase, the resistance value and electricity of available present battery
Second preset charged current value of constant current charging phase locating for pond, then, according to the current resistance value of battery and this
Two preset charged current values, are adjusted the resistance value of adjustable resistance, so as to be equal to this second default for present charging current value
Charging current value.
Specifically, first resistor value R1, i.e., module to be charged are obtained according to fixed voltage value V and preset charged current value I '
Total resistance value, then which calculates adjustable resistance institute according to the current resistance value R of first resistor value R1 and battery
The second resistance value R2=R1-R needed, later adjusts the resistance value of adjustable resistance to R2.
Since the charging current value of constant current charging phase is greater than the charging current value of pre-charging stage, in electricity
When pond enters constant current charging phase by pre-charging stage, the resistance value of adjustable resistance can be reduced, so that the current charging
Electric current be equal to constant current charging phase require the second preset charged current value, and due to internal resistance to negative direction change (i.e.
The direction that resistance value becomes smaller), therefore, after the resistance value for reducing adjustable resistance, it is also necessary to control the resistance value of adjustable resistance to pros
It is adjusted to variation (i.e. resistance value become larger direction), and the resistance change rate of variable resistance in the positive direction can be equal to the internal resistance of cell
Resistance change rate in negative direction.
(2), preset charged parameter value includes preset charge voltage value.
Step " according to the current resistance value of battery and the preset charged parameter value, is adjusted the resistance value of the adjustable resistance
Save, so that current charging parameter value is equal to the preset charged parameter value " may include:
According to the fixed voltage value, the preset charge voltage value and the current resistance value of battery, the adjustable resistance is obtained
Required target resistance value；
The resistance value of the adjustable resistance is adjusted to the target resistance values, so that current charging voltage value is equal to preset charged
Voltage value.
For example, when battery is in the constant voltage charging stage, due to needing to keep battery two in constant voltage charging section
The charging voltage at end is preset charge voltage value, it is therefore desirable to the resistance of variable resistance is adjusted, so that present battery
The charging voltage at both ends is equal to preset charge voltage.Specifically, locating for the resistance value R0 and battery of available present battery
The preset charge voltage value V1 in constant voltage charging stage, then, according to the current resistance value R0 of fixed voltage value V, battery with
And preset charge voltage value V1, the resistance value of adjustable resistance is adjusted, is filled so that current charging voltage value is preset equal to this
Piezoelectric voltage value.
For example, charging current I=V1/ can be obtained according to battery current resistance value R0 and preset charge voltage value V1
Then R0 the target resistance value R2 of adjustable resistance is calculated by formula R2=(V-V1)/I, finally by the resistance value of adjustable resistance
It is adjusted to R2.
The internal resistance of general battery is as charging duration is ever-reduced, therefore in order to guarantee to protect in the corresponding charging stage
It holds in the case where preset charge voltage is horizontal, it is also necessary to which the resistance for allowing the resistance change rate of variable resistance to be equal to the internal resistance of cell becomes
Rate.Namely the resistance value of the adjustable resistance " is adjusted to the target resistance values, so that current charging voltage value is equal in advance by step
If charging voltage value " may include:
The resistance value of the adjustable resistance is adjusted to the target resistance values, and keeps the resistance of variable resistance in the positive direction
Change rate is equal to the resistance change rate of the internal resistance of cell in a negative direction, so that the present charging current value is equal to preset charge voltage
Value.
The charging voltage for needing to keep battery both ends in constant voltage charging section is preset charge voltage value, is entered in battery
The resistance value of adjustable resistance is adjusted to after target resistance value by the battery stage, it is also necessary to keep the resistance of variable resistance in the positive direction
Change rate is equal to the resistance change rate of the internal resistance of cell in a negative direction, so that the charging voltage at battery both ends is consistently equal to pre-
If charging voltage value.
With reference to Fig. 4, for correspondence charging stage shown in Fig. 2, the change in resistance schematic diagram of variable resistance.In precharge rank
Section, resistance value slowly rises, when cell voltage is equal to pre-charge voltage threshold value, resistance value at this time when into constant current charging phase
Become smaller, so that charging current needed for currently charging current is equal to constant current charging, then, in constant current charging phase
The resistance value is gradually increasing to offset becoming larger for the internal resistance of cell.
When cell voltage is equal to the voltage threshold of constant voltage phase, when into the constant voltage charging stage, the resistance value
It is gradually increasing to offset becoming larger for the internal resistance of cell.When charging current is equal to and terminates charging current threshold value, resistance value, which becomes larger, to be dragged down
Charging current, so that charging current is equal to preset termination charging current, the internal resistance of cell is basicly stable at this time, and therefore, resistance value exists
Termination phase can remain unchanged.When cell voltage later is lower than recharge phase is entered if recharging voltage threshold, this
When can increase resistance value and draw high charging current so that charging current is equal to the charging current of constant current charging phase, due to electricity
Pond internal resistance is basicly stable, and therefore, resistance value can be remained unchanged in termination phase.It, can also be again in some other embodiments
Resistance value can also be increased in charging stage, to offset becoming larger for the internal resistance of cell.
From the foregoing, it will be observed that the embodiment of the present invention is in constant voltage required when the constant voltage charging stage using battery is obtained
Then value obtains corresponding fixed voltage value according to the constant voltage values, give module loading to be charged according to the fixed voltage value
Corresponding charging voltage, the module to be charged include the battery and adjustable resistance being serially connected, in the process of charging the battery,
The resistance value of the adjustable resistance is adjusted, so that the current charging parameter value of the battery meets the parameter of locating charging stage
Value requires.The program can give end cell charging can be with without continuously adjusting the input voltage with fixed input voltage
Improve the charging rate of terminal.
It in a preferred embodiment, will be by taking battery charge controller be integrated in the terminal as an example, to introduce charging of the invention
Control method.The terminal can be PC (personal computer, personal computer), laptop, smart phone etc..

204, terminal in the process of charging the battery, monitors the current cell voltage of battery.
205, terminal determines charging stage that battery is presently according to the cell voltage.
It is in constant current charging phase for example, then determining when the voltage of battery is greater than pre-charge voltage threshold value, works as electricity
When the voltage of pressure is greater than constant-voltage charge voltage threshold, it is determined that be in the constant voltage charging stage.
206, terminal obtains the current resistance value of the battery and the battery is presently in charging stage corresponding preset and fills
Electrical parameter values.
Wherein, preset charged parameter value may include preset charged electric current, preset charge voltage etc..For example, being pre-charged
In the stage, which is the first preset charged current value, in constant current charging phase, the preset charged parameter value
It can be the second preset charged current value (wherein, the second preset charged electric current is greater than the first preset charged current value), constant
The voltage charging stage, the preset charged parameter value can be preset charge voltage value, etc..
207, terminal carries out the resistance value of the adjustable resistance according to the current resistance value of battery and the preset charged parameter value
