Fig. 1 shows the flow chart of some embodiments of the condition detecting of storage-battery according to the disclosure.
As shown in Figure 1, condition detecting of storage-battery includes: step 110, the group end voltage of battery group to be measured is obtained；
Step 120, voltage-time curve is established；With step 130, the property of battery group to be measured is judged according to voltage-time curve
Energy.
The performance detection of battery group carries out in the discharged condition.Fig. 6 shows mesuring battary group and electricity in detection process
Press the connection relationship of detection device.As shown in fig. 6, battery group 60 to be measured includes N number of subgroup in parallel, each subgroup is by multiple
Single battery is in series.The number of the single battery of each subgroup can be it is identical, be also possible to it is different, such as the 1st
Subgroup is in series by k single battery, and i-th subgroup is in series by l single battery, and i-th subgroup is by m monomer electricity
Pond is in series.Voltage check device 61 is connected in parallel on the both ends of battery group 60 to be measured, is used for measurement group end voltage.
In step 110, in the discharged condition, acquisition detects within the predetermined time (alternatively referred to as " during detection ")
The group end voltage of battery group to be measured under discharge condition.The performance of usually detection battery group needs to discharge nearly 10 in the related technology
A hour, and in some embodiments of the present disclosure, the predetermined time is no more than the 5% of entire discharge time, such as 30 minutes left sides
It is right.It, can be with the group end voltage of preset frequency (such as 1Hz) real-time detection battery group to be measured in during the test.
In the step 120, according to the group end Voltage Establishment voltage-time curve of acquisition.
In step 130, the performance of battery group to be measured is judged according to voltage-time curve.
Since each single battery has lower voltage limit, entire battery group also has lower voltage limit (to can be described as " the first threshold
Value "), it is lower voltage limit × single battery quantity of single battery.Once the voltage of a certain section single battery in discharge process
Lower than its lower voltage limit, then it will lead to the group end voltage of battery group lower than its lower voltage limit, this just illustrates to deposit in this group of battery
In problematic or poor performance battery.In some embodiments, lower voltage limit can be the predetermined percentage of nominal voltage.Example
Such as, when discharge current is not more than 0.25C10, predetermined percentage can take 90%, and when discharge current is greater than 0.25C10,
Predetermined percentage can take 87.5%.
That is, in during the test, when corresponding group of end voltage of any point is lower than the first threshold on voltage-time curve
When value, it can be determined that the performance of the battery group is poor.
In addition to above-mentioned voltage-time curve, according to the difference of battery performance, it is also possible to other kinds of voltage-occur
Time graph.For example, Fig. 2 shows the schematic diagrames of another kind of voltage-time curve.
It can be seen that the progress with electric discharge from voltage-time curve shown in Fig. 2, the group end voltage of battery group is first
Decline reaches minimum point A quickly, that is, first point that tangent slope is zero occurs, the corresponding voltage value of this point is defined as the bottom of a pan
Voltage Vg；And then, group end voltage starts quickly to go up to reach a high point B, that is, the second point that tangent slope is zero occurs, this
A little corresponding voltage value is defined as hump voltage Vt；Group end voltage held stationary decline later.
Inventor has found during battery group discharge test: the bottom of a pan voltage Vg and hump voltage Vt are accumulator properties
Important Characteristic Points, the bottom of a pan voltage Vg can characterize whether internal storage battery chemical substance has corresponding respond, and hunchbacked
Peak voltage Vt can characterize rise ability of the battery during electric discharge starts.If not occurring the bottom of a pan on voltage-time curve
Voltage and hump voltage then show that the performance of the battery group is poor.
Do not occur the bottom of a pan when the tangent slope of every bit on voltage-time curve is all not zero according to above-mentioned discovery
Voltage and hump voltage then may determine that the performance of the battery group is poor.
Inventor shows it is also found that: difference between obtained the bottom of a pan voltage Vg and its standard value Vb is smaller during detection
The performance of battery group is better；And hump voltage Vt always occurs in pairs with the bottom of a pan voltage Vg, and difference between the two is bigger,
Show that the performance of battery group is better.
According to above-mentioned discovery, if the difference between the bottom of a pan voltage Vg on voltage-time curve and its standard value Vb is big
In preset threshold value (can be described as " second threshold "), then it may determine that the performance of the battery group is poor.In some embodiments,
Vb is tangent slope on voltage-time curve that the battery group discharge test of voltage class good (for example, 100% capacity) obtains
First point of corresponding standard voltage value for being zero, second threshold can be the predetermined percentage of standard value Vb.
Above-mentioned relation can be characterized with performance parameter S, that is, S=(Vb-Vg)/Vb-a, wherein a is depending on different storages
The parameter of battery, generally much smaller than 1, for example, 0.2%.Work as S > 0, i.e. when Vb-Vg > Vb × a, i.e. the bottom of a pan voltage Vg and its standard
When difference between value Vb is greater than second threshold, it can be determined that the performance of the battery group is poor.And work as S≤0, then it can pass through
Another performance parameter Q further judges the performance of battery group.
Q depends on the difference of the bottom of a pan voltage and hump voltage.Relationship between Q and its standard value Qb can reflect battery
The performance of group.Standard value Qb is parameter depending on accumulator capacity etc., value in a certain range, for example, [Qb1,
Qb2].In Q < Qb1, show that the performance of battery group is poor；And when Q is in standard value range, i.e. when Q ∈ [Qb1, Qb2], Q
It is bigger, show that the performance of battery group is better.
In some embodiments, Q=(Vt-Vg)/I, wherein I indicates the rated capacity of battery group in predetermined time (example
Such as 10 hours) electric current needed for interior discharge off.That is, when the difference between hump voltage Vt and the bottom of a pan voltage Vg is less than
When preset threshold value (can be described as " third threshold value "), it can be determined that the performance of the battery group is poor.As it appears from the above, third threshold value
It is determined by rated capacity electric current needed for interior discharge off of battery group to be measured, such as Qb1 × I can be expressed as.
It should be appreciated that above-mentioned performance parameter S and Q is all based on same voltage class (- 48V, 220V, 380V, 480V system
System etc.) it is compared.For same voltage class, performance parameter S < 0, the Q value of battery group to be measured is bigger, then proves storage to be measured
The performance of battery pack is better.
Judgment mode through the foregoing embodiment can quickly judge the performance of battery group to be measured, so as to
First quickly check out problematic battery group.It is then possible to be directed to problematic battery pack fast lock by similar mode
Fixed problematic single battery, and abnormality alarming prompt can be issued.Targetedly effective measures, energy are taken on this basis
It is enough fast and effeciently to prevent existing security risk, guarantee the normal operation of electric system；The work of detection can be greatly reduced
Amount improves working efficiency.
Problematic battery group is checked, can also be judged by the current balance of the subgroup included by it.Or
Person can be asked after checking out problematic battery group by the current detecting of each subgroup come quick lock in performance
The single battery of topic.

In the step 310, the group end electric current of each subgroup of mesuring battary group is obtained.Detection is shown with reference to Fig. 6, Fig. 6
The connection relationship of mesuring battary group and current detection means in the process.As shown in fig. 6, each subgroup and an electric current electric probe device
Series connection: the 1st subgroup is connected with current detection means 631, and i-th subgroup is connected with current detection means 63I, and n-th is sub
Group is connected with current detection means 63N, and so on.In some embodiments, each subgroup can detecte during the test
Multiple groups of end current values.
Then, in step 320, the average value of the group end electric current of each subgroup is calculated.
The difference of the average value of the group end electric current of each subgroup reflects the harmony of battery group.Next, in step
330, according to the difference between each average value, judge the harmony of battery group to be measured.It in some embodiments, can be by each son
Maximum value in the average value of the group end electric current of group is denoted as imax, and minimum value is denoted as imin, and average value is denoted as iavg, then electric current
Otherness can indicate with parameter D, i.e. D=(imax-imin)/iavg.The D the big, show battery group harmony more
Difference, and it is poorer to organize the smaller subgroup performance of end electric current.
As an example it is supposed that battery group has 3 subgroups, measurement obtains the electric current of each subgroup during the detection of electric discharge
Average value is respectively 30A, 31A and 35A, then imax is 35A, imin 30A, iavg 32A, be calculated D=(35-31)/
32=1/8.For the battery of different voltages grade, from the available different judgement of the calculated result.For example, for 48V
Battery group, D value are greater than 5% and show that harmony is bad.That is, the 1/8 current difference opposite sex carrys out 48V battery group
Say that expression is harmonious bad.However, it should be understood that 1/8 current difference is anisotropic for the battery group of other voltage class
It may also indicate harmonious good.
