The processing answered.The refinement maintenance of battery is reached, extends the service life of battery, cost is saved.
Brief description of the drawings
Fig. 1 is the flow chart of the detection method of accumulator failure of the present invention.
Embodiment
Below by drawings and Examples, technical scheme is described in further detail.
Fig. 1 is the detection method of accumulator failure of the present invention, as illustrated, the present invention specifically includes following steps：
Step 101, collection battery operational data in continuous and long under working long hours；
Specifically, can every Fixed Time Interval gather battery working long hours under it is long when operational data.
Collate the minutes battery related data to " tables of data ", include but is not limited to：Battery brand, the networking time limit, stop
The electric frequency, power failure duration, load of base station, visual condition etc..
Step 102, according to it is long when operational data obtain the working curve of the battery；
Battery is run after the long-term data acquisition tracking of progress and collection, can be shown by the method for visualization
Go out the data and curves of various required dimensions.For example stored by suitable time interval (collection in such as every 8 minutes is once) acquisition and recording
The service data of battery, with the corresponding time of the record gathered data of cloth.
The battery data of collection includes but is not limited to：Voltage, electric current, temperature.Focusing on for the collection of data is long-term
The data of each dimension are kept track of, vertical analysis data improve the trackability of data.Power failure number can be recorded from different dimensions
According to being recorded as " data and curves ", the dimension of curve includes but is not limited to, by area record, record by month, long by power off time
Short record, power failure data etc..
Step 103, data analysis is carried out according to the working curve, obtains the fault message of battery.
Specifically, data analysis can be carried out according to the working curves of different dimensions, so as to export different results letters
Breath.
For example, when working curve is voltage-time curve, the current performance of initial analysis battery；The original of institute's foundation
It it is then the voltage stabilization stage during being discharged in voltage _ time graph.
When the voltage-time curve is slowly reduced, illustrating accumulator property preferably, output battery fault-free is believed
Breath；
When the voltage-time curve is parabola, judgement may export battery with the presence of backward cell batteries
In have backward cell batteries information；
When having flex point in the voltage-time curve, judgement has backward cell batteries, it may be possible to have partial monosomy
Battery, which has been discharged in electricity, output battery, partial monosomy battery discharge off information；
For example, when working curve is current versus time curve, during electric discharge, two group storage batteries and alliance electric discharge.
When the current versus time curve leading portion has electric current bifurcated, judgement is probably because in one of which battery
Resistance is larger, there is backward cell batteries, the big information of one group storage battery internal resistance of output, and the letter with backward cell batteries
Breath；
When the current versus time curve back segment has electric current bifurcated, judge that two group storage battery performances are unbalanced, there is one group
Storage battery practical capacity is smaller, and two group storage battery performances of output are unbalanced, there is the less information of group storage battery actual capacity.
Again as shown in figure 1, the present embodiment also comprises the following steps：
Step 104, according to the backwardness cell batteries information of output, the area inquired about where the backward cell batteries
Information, the battery of the regional information location is detected using discharge instrument, specific lagging batteries are obtained；
Fall behind monomer electric power storage specifically, being inquired about according to the performance information of the battery of the output of data processed result above
The base station of pond location, further does discharge test to the battery of the base station, finds specific backward cell batteries,
And discharge examination is carried out to the backwardness cell batteries and information is gathered.
Further, when doing discharge test, the battery of different capabilities can be discharged by different hour rates.For example lead to
Normal 500AH battery discharges by 5 hour rates.Discharge instrument can filter out backward monomer by discharge data, and can calculate every
The capacity of individual monomer and internal resistance.Under normal circumstances, the time used is 2 when the battery discharging of nominal capacity is to 1.8 volts
Hour or so.
Step 105, the lagging batteries are detected, processing information is exported.
The tables of data for the data formation that above-mentioned basis is collected, data and curves, discharge test information carry out data analysis and obtained
To information the reason for accumulator failure.Concrete foundation principle can be：
Internal resistance increase, capacity decline battery, be the reason for possible because be chronically at discharge condition, not in time charge,
The charge less that undercharge, float charge voltage are too low, frequent deep discharge etc. is caused；Long-term floating charge；Temperature is low.
The reason for internal resistance is small, capacity declines is probably that temperature is high.
The reason for leakage is probably electrolyte rich solution, large current charge, temperature height etc..
Can be reduced with reference to the result that the related data and the above that are counted in tables of data are analyzed cause battery decline because
Plain scope, so as to export processing result information.
It is probably specifically following information：
Change monomer：Suitable for by safeguarding expendable battery.
Plus electrolyte liquid：Suitable for because of the withered battery of dehydration.
Adjust Switching Power Supply parameter：The battery that can be recovered by management of charging and discharging suitable for battery performance.It is adjustable
Parameter is：Even charging voltage, float charge voltage fills the time, fills the cycle, cut-off current, principal voltage, second voltage etc.
Deng.
It is limited in year 1 year for example, certain battery networks, the moon power failure frequency is 53 times/month, loads 50A, voltage-time curve
, there is obvious flex point in the voltage stabilization stage in figure, after discharge the phase decline rapidly, current versus time curve figure, during discharging
There is obvious bifurcated.It is being exported after data analysis as a result, by voltage-time curve and current versus time curve figure, can be true
Determine there are backward cell batteries in battery；The i.e. exportable preliminary judgement information of the power failure frequency is analyzed again, and battery is due to frequent
Discharge and recharge result in battery charge less, vulcanization is serious, occurs in that backward cell batteries；Discharge test is done to whole group based on this,
Test out all specific backward cell batteries；According to the service life information of battery, output battery can be opened by adjustment
Close power parameter to repair the information of battery, even charging voltage should be improved after now handling, the time is filled in extension, as far as possible with small electricity
Stream charges farthest to weaken sulfation for a long time.
The detection method of accumulator failure of the present invention according to the historical data and current data of the battery collected, according to
The data can be obtained by the current state output fault message of battery, battery be carried out according to the fault message relative
The processing answered.The refinement maintenance of battery is reached, extends the service life of battery, cost is saved.
