CPU 21 timing acquiring cell voltage Va0 and time Ta0 first, then interval time Δ T, acquires cell voltage
Then Vb0 and time Tb0, subsequent calculating difference Δ V0=Va0-Vb0 are found immediate with Va value from discharge curve data
Voltage value Va1 and time Ta1 and next data Vb1 and Tb1, and calculating difference Δ V1=Va1-Vb1, then select Δ
Difference minimum curve between V0 and Δ V1, as remaining capacity calculate reference curve, then calculate remaining capacity=curve it is total when
M- Ta0, remaining capacity ratio=remaining capacity/curve total time, the subsequent show percent on display screen 7, or press score
It is shown than segmentation, when remaining capacity is lower than 10%, provides low capacity prompt user, then system repeats the above steps step, adopts
Collection calculates and shows electricity.When battery reaches " minimum voltage ", (note: battery cannot make power management chip export burning voltage
Minimum, depend on power management chip) when, the battery voltage information of record and working time are stored as new battery and put
Electric curve A0 forms a curve A0 ' to the secondary derivation of the voltage of new curve and all numerical value after derivation is all subtracted derivation
The average value of all data afterwards forms a new curve A0 〞, then all data are averaged by curve A0 〞, then
It is compared one by one with the calculated average value of the same method of other curves, if difference is less than or equal to 5, original song will be deleted
Line saves new curve, and when difference is greater than 5, original curve is constant, increases new curve newly, to complete the storage to new curve, realizes
The detection of battery capacity acts on.
Working principle: work ahead, S1 use disposable battery 3, when product works normally, timing Δ T collection voltages
Signal V0；
S2, continuous recording voltage signal and working time form the curve of cell voltage and working time, i.e. battery discharge
Voltage/time curve；
S3 repeats the above steps the battery of common different brands in the market, forms cell voltage and working time
Curve；
S4 summarizes above-mentioned a plurality of battery discharge curve, forms a discharge curve database, is integrated into memory 23
In.
Work is detected, S1, after product powers on, control CPU 21 detects pressure at interface 5 by pressure sensor 26, adjusts
25 control 4 startings of negative pressure pump/stoppings or air pump speed of air pump driving make pressure at interface 5 reach the stationary value of setting；
21 timing of S2, CPU by 22 acquisition battery terminal voltage values and working time of AD acquisition, by collected one group or
Multi-group data carries out calculating analysis, compares with the battery discharge curve in memory 23, selects an immediate curve, root
The ratio of remaining capacity is conversed according to the curve, then passes through display screen 7 for remaining capacity percentage or the situation indications of segmentation
Out, if electricity is lower than the 10% of total electricity, low capacity prompt is provided by display screen 7, CPU 21 repeats aforesaid operations, continues
Detection battery capacity is simultaneously shown, when battery reaches " minimum voltage ", the battery voltage information of record and working time are stored
New discharge curve is retained into new curve according to similarity degree with legacy data library curve comparison for new battery discharge curve,
Or old curve is deleted, system cut-off shutdown；
Calculation, CPU 21 timing acquiring cell voltage Va0 and time Ta0, then interval time Δ T, acquires battery
Voltage Vb0 and time Tb0, subsequent calculating difference Δ V0=Va0-Vb0, then finds from discharge curve data and most connects with Va value
Voltage value Va1 and time Ta1 and next data Vb1 and Tb1, and calculating difference Δ V1=Va1-Vb1 then selects
Difference minimum curve between Δ V0 and Δ V1, as the reference curve that remaining capacity calculates, then to calculate remaining capacity=curve total
When m- Ta0, remaining capacity ratio=remaining capacity/curve total time, the subsequent show percent on display screen 7, or by than
Point than segmentation display, when remaining capacity is lower than 10%, low capacity prompt user is provided, then system repeats the above steps step,
Acquisition calculates and shows electricity, and when battery reaches " minimum voltage ", the battery voltage information of record and working time are stored
For new battery discharge curve A0, a curve A0 ' is formed to the secondary derivation of the voltage of new curve, by all numbers after derivation
Value all subtracts the average value of all data after derivation, forms a new curve A0 〞, then all data by curve A0 〞
It is averaged, is then compared one by one with the calculated average value of the same method of other curves, if difference is less than or equal to
5, original curve will be deleted, new curve is saved；When difference is greater than 5, original curve is constant, increases new curve newly, to complete to new
The detection effect of battery capacity is realized in the storage of curve.
It can to sum up obtain, there is the negative pressure drainage instrument of electric quantity detection function to be capable of providing stable negative pressure for this, and can be suitble to difference
The disposable battery of brand or producer can accurately calculate battery dump energy, provide capacity prompt, remind user's replacement in time
Battery, while battery capacity can be more fully utilized, and avoid the case where not prompting and power off in advance, to guarantee that product continues
It is used with effective.
