In embodiments of the present invention, according to online battery duration efficiency, the matching with the discharge performance of actual battery,
It can intuitively judge that situation is lost in battery efficiency, because electric discharge is the actual discharge that is obtained according to actual existing network load testing
Duration, therefore our station electric discharge standby duration ability has also directly been reacted, it is to have very strong data convincingness.
Now with the online discharge test data instance of base station storage batteries, apply the technical scheme of the present invention and made a concrete analysis of,
As shown in Figure 2.
The specification of base station storage batteries is 150AH/48V, and the average current of test is 10.54A, discharges into the 47V electricity of setting
Pressure, take 667 minutes (11.1 hours), therefore a length of 11.1 hours during the actual discharge of current base station battery.Due to current
For a certain certain base station battery, environment temperature corresponding to base station storage batteries is 25 DEG C, then t value is 25 DEG C, and η takes
It is set to 1, α and takes fixed 0.006, Q 150AH, be calculated during theoretical discharge a length of 11.38 hours, then base station storage batteries efficiency value
=actual discharge duration (11.1h) ÷ theoretical discharges duration (11.38h), it is 0.9766 to draw base station storage batteries efficiency value.
Technical solution of the present invention, based on existing network Internet resources and monitoring system, on the premise of network operation safety is met,
By implementing remote auto discharge test to battery, by the data collection and analysis of science, output really exists in net battery
Line duration efficiency, endurance of storage battery assessment is obtained, battery can be made full use of, and then improve network stabilization, reduced
Operation cost, preferably serve project management and commodity network operation.
In the such scheme of the embodiment of the present invention, base station storage batteries efficiency value can truly reflect the loss feelings of battery
Condition, but this is based on the parameter for battery draw after deep discharge in 47V, in the real work of battery asset management
Middle manager only may only wonder whether this battery pack efficiency situation is less than some given critical condition, rather than accurately
Some numerical value, quickly to judge whether that needs scrap replacement.Therefore the method for the embodiment of the present invention also includes：

Discharge-rate corresponding to first electric discharge sample curve, by the magnitude of voltage at each testing time point of acquisition with first electric discharge mark
In this curve at corresponding testing time point corresponding to magnitude of voltage be compared, battery to be assessed and critical report can be judged quickly
The magnitude of voltage height difference of useless condition curve sample, by the evaluation to magnitude of voltage corresponding at these testing time points, no
Need when battery discharging is completed, it is possible to evaluate base station storage batteries and scrap condition curve sample battery efficiency height with critical
Low correction data, and then the more critical evaluation for scrapping state sample battery efficiency height is made to battery.
Wherein, the magnitude of voltage at each testing time point is compared with corresponding magnitude of voltage in the first electric discharge sample curve
Compared with when obtaining the assessment result of base station storage batteries according to comparative result：In each testing time point, when corresponding magnitude of voltage is small
The quantity of the testing time point of corresponding magnitude of voltage and the ratio of number of total testing time point are big in the first electric discharge sample curve
When 1/2, determine that the efficiency value of base station storage batteries is less than the first efficiency value corresponding to critical condition；In each testing time point
In, when corresponding magnitude of voltage is more than the quantity of the testing time point of corresponding magnitude of voltage and total test in the first electric discharge sample curve
When the ratio of number at time point is more than 1/2, determine that the efficiency value of base station storage batteries is more than the first efficiency value corresponding to critical condition.
Specifically, in each testing time point of battery to be assessed, it is corresponding at the testing time point more than half
Magnitude of voltage when being all higher than corresponding magnitude of voltage in the first electric discharge sample curve, it may be determined that the efficiency value of base station storage batteries is more than
First efficiency value corresponding to critical condition, now the state of base station storage batteries scrap state better than critical.In battery to be assessed
Each testing time point in, magnitude of voltage corresponding at the testing time point more than half is respectively less than the first electric discharge sample curve
In corresponding magnitude of voltage when, it may be determined that the efficiency value of base station storage batteries is less than the first efficiency value corresponding to critical condition, now
The state of base station storage batteries is inferior to critical scrap state.
As shown in figure 3, it is that the critical battery for scrapping state is imitated to set discharge-rate as the 52% of 0.03C efficiency battery
Can curve, the discharge-rate of tested batteries is also 0.03C, often by 30 minutes we compare once with target curve
Difference, as shown in table 2, it can be found that the voltage at 6 test points is below target curve, then can be determined that the batteries
Efficiency is the object that innovation is needed in our engineerings under 52%.
