Example IV, the battery with capacity as 2560mAh, the charging charged using the charging adapter of 900mA
Journey is further described for specific embodiment.
Fig. 2 is a kind of charging adapter Automatic adjusument charging interval system specific embodiment lithium cell charging mistake of the invention
Journey voltage-time curve figure, as shown in Fig. 2 when battery charge is 900mA, cell voltage is charged to 3.84V the from 3.7V
The charging in one stage is similar to linear-charging, and the charging that cell voltage is charged to 4.0V second stage from 3.9V is similar to linearly fill
Electricity, the charging that cell voltage is charged to the 4.1V phase IIIs from 4.0V is similar to the voltage change Δ U of linear-charging, i.e. battery and fills
Electric time Δ t is directly proportional.According to the charging interval Δ t and voltage change Δ U of battery, the speed v of charging is drawn.
Charging rate v=cell voltage differences Δ U/ charging interval Δs t (1)
The battery of 2500mAh is filled according to the charging adapter that formula (1) can calculate first stage 900mA
The charging rate of electricity
v900=(Ue-Us)/(t1-t0)=(3840-3700)/(33.5-18)=9.03mV/min.
Similarly, can be gone out by experiment test and 1300mA, 1200mA, 1100mA, 1000mA are used in the first stage,
The corresponding charging rate v of 900mA, 800mA, 700mA, 600mA, 500mA, 400mA, 300mA charging adapter charging1300,
v1200, v1100, v1000, v900, v800, v700, v600, v500, v400, v300.Test simultaneously draws 1300mA, 1200mA, 1100mA,
The corresponding time-out time of 1000mA, 900mA, 800mA, 700mA, 600mA, 500mA, 400mA, 300mA charging adapter charging

It is the battery of 2560mAh to use capacity, is charged using different charging currents respectively, draws each charging stage
Test data of experiment, it is as shown in the table：
The charging rate and charging current of different charging stages can be drawn according to upper table.
Fig. 3 is a kind of charging adapter Automatic adjusument charging interval system specific embodiment charging rate detection of the invention
Flow chart, as shown in figure 3, MCU control unit constantly detects the charged state of charging IC and the magnitude of voltage of battery, starts timing
Device, it is 2 hours to preset time-out time, when charging beginning is detected and cell voltage is less than 3.7V, starts to detect charging rate,
When cell voltage is more than 3.7V, start timing, cycle detection cell voltage is more than 3.84V until cell voltage, stop charging
Velocity measuring；Then charging rate v is calculated using above-mentioned formula (1), an immediate charging rate value is matched according to v values
vxIf, vx=45Mv/min, then vxIt is approximately equal to v900, then the charging current of charging adapter can be determined for 900mA,
The charger charging time-out of 900mA should correspond to T900=227min total time, i.e., time-out should be set to 227 points total time
Clock, because being the charging rate for detecting in the first stage, it should be T=T900-T1-T0 to reset time-out time,
Wherein T0=18min, T1=15.83min, then T=227-18-15.83=193.17min.
It is above the implementation of the first detection-phase, but actual user might not can wait battery electric quantity all to use
It is complete to recharge, charged when cell voltage is initially inserted into dispatch from foreign news agency more than 3.7V and when less than 3.9V, will now perform second and examine
The flow in survey stage, it is also possible to dispatch from foreign news agency is initially inserted into more than 3.9V and during less than 4.0V in cell voltage and is charged, will now perform
The flow of the 3rd detection-phase.
In the second detection-phase, MCU control unit constantly detects the charged state of charging IC and the magnitude of voltage of battery, starts
Timer, it is 2 hours to preset time-out time, when charging beginning is detected and cell voltage is higher than 3.9V, starts detection and charges
Speed, starts timing, and cycle detection cell voltage is more than 4.18V until cell voltage, stops charging rate detection；Then use
Above-mentioned formula (1) calculates charging rate v, and an immediate charging rate value v is matched according to v valuesxIf, vx=45Mv/min,
Then vxIt is approximately equal to v900, then the charging current of charging adapter can be determined for 900mA, the charger of 900mA charges time-out always
Time should correspond to T900=227min, i.e., time-out should be set to 227 minutes total time, because being in phase III detection
The charging rate for arriving, so reset time-out time should be
T=T900-T0-T1-T11-T2,
Wherein T0=18min, T1=15.83min, T11=21.17min, T2=47.07min,
Then T=227-18-15.83-21.17-47.07=124.93min.
In the 3rd detection-phase, MCU control unit constantly detects the charged state of charging IC and the magnitude of voltage of battery, starts
Timer, it is 2 hours to preset time-out time, when charging beginning is detected and cell voltage is higher than 4.0V, starts detection and charges
Speed, starts timing, and cycle detection cell voltage is more than 4.0V until cell voltage, stops charging rate detection；Then use
Above-mentioned formula (1) calculates charging rate v, and an immediate charging rate value v is matched according to v valuesxIf, vx=45Mv/min,
Then vxIt is approximately equal to v900, then the charging current of charging adapter can be determined for 900mA, the charger of 900mA charges time-out always
Time should correspond to T900=227min, i.e., time-out should be set to 227 minutes total time, because being in second stage detection
The charging rate for arriving, so reset time-out time should be:
T=T900-T0-T1-T11-T2-T3,
Wherein T0=18min, T1=15.83min, T11=21.17min, T2=47.07min, T3=42.33mim, then
T=227-47.07=82.6min.
Started to charge up in the case that user is more than 4.0V in cell voltage, be unsatisfactory for three conditions of detection-phase,
Time-out time cannot be accurately calculated, so using 2 hours time-out times of default setting.It was verified that during 2 hours overtime
Between will not cause over-charging of battery and trigger deflagration accident.
It 2 hours is 3 different inspections in order to ensure in the case where the minimum current of 300mA charges that default time-out time is
The survey stage can efficiently accomplish detection.
Above is preferable implementation of the invention is illustrated, but the invention is not limited to the implementation
