As in order to ensure the safety that charges, battery charges and needs through 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 is differed, such as, the charging electricity of pre-charging stage
Flow for 100mA, constant-current charging phase charging current be 1000mA, constant voltage charging phase charging voltage be 4.2V, therefore,
The different charging stages needs the resistance to adjustable resistance to carry out different regulations, so that current charge parameter reaches accordingly
Charge parameter is required.Specifically, step " being adjusted to the resistance of the adjustable resistance " can include：
Determine the charging stage that the battery is presently in；
Obtain 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 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 can include preset charged electric current, preset charge voltage etc..Such as, in precharge
Stage, the preset charged parameter value are the first preset charged current value, in constant current charging phase, the preset charged parameter value
Can be the second preset charged current value (wherein, the second preset charged electric current is more than the first preset charged current value), constant
The voltage charging stage preset charged parameter value can be preset charge voltage value, etc..
The present embodiment can in charging process real-time monitoring battery voltage, determine that battery is presently according to the voltage
Charging stage, such as, when battery voltage be more than pre-charge voltage threshold value when then determine in constant current charging phase, when
When the voltage of voltage is more than constant-voltage charge voltage threshold, it is determined that in the constant-potential charge stage.The present embodiment can be with root
The charging stage that battery is presently in is determined according to the duration for charging.Specifically, step " determines the charging that the battery is presently in
Stage " can include：
Obtain the current accumulative charging duration of the battery；
The charging stage that the battery is presently in is determined according to the accumulative charging duration.
Such as, when accumulative charging duration is more than the first duration T1, it is determined that pre-charging stage is in, when accumulative charging duration
During more than the second duration T2, it is determined that constant current charging phase is in, when the 3rd duration T3 is more than in the accumulative charging interval, it is determined that
In constant voltage charging phase ....The T1 ＜ T2 ＜ T3.
Alternatively, it is contemplated that the internal resistance of battery constantly diminishes with the duration for charging, therefore, it is also desirable to so that variable
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 to the resistance of the adjustable resistance, so that current charging parameter value is equal to this and presets filling
Electrical parameter values " can include：
The target resistance of adjustable resistance is determined according to the current resistance value of battery and the preset charged parameter value；
The resistance of the adjustable resistance is adjusted to into target resistance, and keeps variable resistance resistance change rate in the positive direction
Equal to internal resistance of cell resistance change rate in a negative direction, so that the current charging parameter value is equal to preset charged parameter value.
Wherein, variable quantity of the resistance change rate for unit time internal resistance resistance.The positive direction is that resistance becomes big side
To the direction that negative direction diminishes for resistance.
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 to the resistance of the adjustable resistance
Section, so that current charging parameter value is equal to the preset charged parameter value " can 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, the second resistance value needed for the adjustable resistance is obtained；
The resistance of the adjustable resistance is adjusted to into the second resistance value, so that the present charging current value is equal to preset charged
Current value.
Such as, when battery is in pre-charging stage, current resistance value R0 of battery and the residing precharge of battery are obtained
The first preset charged current value I ' in stage, then, according to current resistance value R0 of battery and the first preset charged electric current
Value I ', the resistance of adjustable resistance is adjusted, 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, according to needed for current resistance value R of first resistor value R1 and battery calculates adjustable resistance
Second resistance value R2=R1-R, adjusts the resistance of adjustable resistance to R2 afterwards.
The internal resistance of general battery is as charging duration is ever-reduced, therefore in order to ensure to protect in the corresponding charging stage
Hold under preset charged levels of current, in addition it is also necessary to which the resistance that variable-resistance resistance change rate is equal to the internal resistance of cell is become
Rate.That is, the resistance 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 " can include：
The resistance of the adjustable resistance is adjusted to into the second resistance value, and keeps variable resistance resistance in the positive direction
Rate of change is equal to internal resistance of cell resistance change rate in a negative direction, so that the present charging current value is equal to preset charged electric current
Value.Wherein, variable quantity of the resistance change rate for unit time internal resistance resistance.The positive direction is that resistance becomes big direction, is born
The direction that direction diminishes for resistance.
For example, it is initial charging phase typically in pre-charging stage, the internal resistance of cell is larger, and the preset charged electricity in the stage
Flow valuve is less, in pre-charging stage, the internal resistance of cell will from large to small, therefore, in order to ensure that charging current maintains the rank
In the preset charged levels of current of Duan Yaoqiu, the resistance of adjustable resistance, variable-resistance resistance change rate can be constantly increasing
The resistance change rate of the internal resistance of cell can be equal to, so be can ensure that default equal to first in the current charging current of pre-charging stage
Charging current value.
Equally, such as, when battery is in constant current charging phase, the resistance value and electricity of present battery can be obtained
Second preset charged current value of constant current charging phase residing for pond, then, according to the current resistance value of battery and this
Two preset charged current values, are adjusted to the resistance of adjustable resistance so that present charging current value be equal to this second preset
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, the R1=V/I ' then, calculates adjustable resistance institute according to current resistance value R of first resistor value R1 and battery
Second resistance value R2=R1-R for needing, adjusts the resistance of adjustable resistance to R2 afterwards.
As the charging current value of constant current charging phase is more than the charging current value of pre-charging stage, therefore, in electricity
When pond enters constant current charging phase by pre-charging stage, the resistance of adjustable resistance can be reduced, so that the current charging
Electric current is equal to the second preset charged current value that constant current charging phase is required, and as internal resistance changes (i.e. to negative direction
The direction that resistance diminishes), therefore, after the resistance for reducing adjustable resistance, in addition it is also necessary to control the resistance of adjustable resistance to pros
Adjust to change (i.e. resistance becomes big direction), and variable resistance resistance change rate in the positive direction can be equal to the internal resistance of cell
To the 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 to the resistance of the adjustable resistance
Section, so that current charging parameter value is equal to the preset charged parameter value " can include：
According to the current resistance value of the fixed voltage value, preset charge voltage value and the battery, the adjustable resistance is obtained
Required target resistance；
The resistance of the adjustable resistance is adjusted to into the target resistance values, so that current charging voltage value is equal to preset charged
Magnitude of voltage.
Such as, when battery is in the constant-potential charge stage, due to needing to keep battery two in constant-potential charge section
The charging voltage at end is preset charge voltage value, it is therefore desirable to variable-resistance resistance is adjusted, so that present battery
The charging voltage at two ends is equal to preset charge voltage.Specifically, can obtain residing for resistance value R0 and battery of present battery
Preset charge voltage value V1 in constant-potential charge stage, then, according to current resistance value R0 of fixed voltage value V, battery with
And preset charge voltage value V1, the resistance of adjustable resistance is adjusted, so that current charging voltage value is equal to this and presets filling
Piezoelectric voltage value.
Such as, charging current I=V1/ can be obtained according to current resistance value R0 of battery and preset charge voltage value V1
R0, then, is calculated target resistance R2 of adjustable resistance by formula R2=(V-V1)/I, finally by the resistance 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 ensure to protect in the corresponding charging stage
Hold under preset charge voltage level, in addition it is also necessary to which the resistance that variable-resistance resistance change rate is equal to the internal resistance of cell is become
Rate.Namely the resistance 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 " can include：
The resistance of the adjustable resistance is adjusted to into the target resistance values, and keeps variable resistance resistance in the positive direction
Rate of change is equal to internal resistance of cell resistance change rate 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 two ends in constant-potential charge section is preset charge voltage value, is entered in battery
The battery stage adjusts the resistance of adjustable resistance to target resistance, in addition it is also necessary to keep variable resistance resistance in the positive direction
Rate of change is equal to internal resistance of cell resistance change rate in a negative direction, so that the charging voltage at battery two ends is consistently equal to pre-
If charging voltage value.
With reference to Fig. 4, it is to correspond to the charging stage shown in Fig. 2, variable-resistance change in resistance schematic diagram.With in precharge rank
Section, resistance slowly rises, when cell voltage is equal to pre-charge voltage threshold value, into now resistance during constant current charging phase
Diminish, so that current charging current is equal to the charging current needed for constant current charge, then, in constant current charging phase
The resistance is gradually increasing big to offset the change of the internal resistance of cell.
When cell voltage is equal to the voltage threshold of constant voltage phase, during into the constant-potential charge stage, the resistance
It is gradually increasing big to offset the change of the internal resistance of cell.When charging current is equal to termination charging current threshold value, resistance change is dragged down greatly
Charging current, so that charging current is equal to preset termination charging current, now the internal resistance of cell is basicly stable, therefore, resistance exists
Termination phase can keep constant.When cell voltage afterwards is less than recharge phase is entered if recharging voltage threshold, this
When can increase resistance 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, therefore, resistance can keep constant in termination phase.In some other embodiments, can be with again
Resistance can also be increased in charging stage, it is big with the change for offsetting the internal resistance of cell.
From the foregoing, it will be observed that the embodiment of the present invention adopts acquisition battery to be in constant voltage required during the constant-potential charge stage
Value, then, obtains corresponding fixed voltage value according to the constant voltage values, gives module loading to be charged according to the fixed voltage value
Corresponding charging voltage, the module to be charged includes battery and the adjustable resistance being serially connected, during charging to battery,
The resistance of the adjustable resistance is adjusted, so that the current charging parameter value of the battery meets the parameter of residing charging stage
Value is required.The program can charge to end cell with fixed input voltage, without the need for constantly adjusting the input voltage, can be with
