Wherein, C represents the rated capacity of battery, 0.1,0.2,0.3...... is discharge coefficient, 0.1C, 0.2C, 0.3C...... represent the discharge current of battery when discharging, 50.2V, 49.6V, 49.0V...... represent battery when using different discharge currents to discharge, the value of the theoretical voltage during through different time.
Need to prove, the data that measure in the table 1, the battery of use should be the battery that does not ideally have natural wastage, and the rated capacity C of battery is the real account constant volume.
For example, suppose that the rated capacity of battery reality is 100AH, 0.1C, 50.2V, 60 (Min) expression of the 2nd row is discharged after 60 minutes when battery discharges with the electric current of 0.1 * 100=10A in the table 1, and the voltage of battery drops to 50.2V.
Need to prove, in the present embodiment, because the rated capacity of battery reality is 100AH, and discharge current is 10A, when battery discharges, the battery controller actual measurement obtain at the electric current that uses 10A during through different discharge time, the measurement result of virtual voltage should coming to the same thing as the 2nd row in the table.
Step 202, battery controller obtain under the rated capacity of current discharge current and current configuration, through the theoretical voltage of different discharge times.
Further, battery controller obtains under the rated capacity of current discharge current and current configuration, theoretical voltage through different discharge times, specifically comprise: battery controller reads in the above-mentioned mapping, and battery is pairing through the theoretical voltage of difference during discharge time under the rated capacity of using current discharge current and current configuration.
Concrete in the present embodiment is, since the rated capacity of current battery in battery controller by the artificial 50AH that is configured to, therefore battery is under the discharge current of the rated capacity of current configuration and 10A, theoretical voltage is shown in the 3rd column data in the table 1 after passing through the difference discharge of discharge times, after the discharge time through 10min, 35min, 60min, 90min......, the theoretical voltage of battery is 50.2V, 49.6V, 49.0V, 48.4V.......
Step 203, judge battery through identical discharge time the time theoretical voltage and the absolute value error of virtual voltage whether meet default rule, if, the rated capacity mistake of the current configuration of battery then, execution in step 204, if not, then the rated capacity of the current configuration of battery is correct;
Further, default regular concrete be: | theoretical voltage-virtual voltage |＞preset value, and along with continuing of discharge time, | theoretical voltage-virtual voltage | increase, wherein, preset value is determined according to the accuracy requirement that battery rated capacity configuration error is detected, accuracy requirement is big more, and preset value is more little, and accuracy requirement is more little, preset value is big more, | theoretical voltage-virtual voltage | the absolute value error of=theoretical voltage and virtual voltage.
Correspondingly, judge battery through identical discharge time the time theoretical voltage and the absolute value error of virtual voltage whether meet default rule, be specially: theoretical voltage and the virtual voltage of battery when passing through identical discharge time subtracted each other, obtain difference, and above-mentioned difference taken absolute value obtain absolute value error, judge that whether this absolute value error is greater than preset value, and along with continuing of discharge time, it is big whether above-mentioned absolute value error becomes, if, then above-mentioned absolute value error meets default rule, if not, then above-mentioned absolute value error does not meet default rule.
For example, in the present embodiment, the setting preset value is 0.1V, when the rated capacity with the current configuration of battery is 50AH, after discharge 60 minutes, the virtual voltage of battery drops to 50.2V, and dispose under the correct situation in rated capacity according to battery in the table 1, after discharge in 60 minutes, the theoretical voltage of battery should drop to 49.0V, above-mentioned theory voltage and virtual voltage is subtracted each other and take absolute value obtain absolute value error 1.2V, absolute value error 1.2V is greater than preset value 0.1V, satisfy the condition of " | theoretical voltage-virtual voltage |＞preset value ", after discharge 120 minutes, the virtual voltage of battery drops to 49.6V, and according to battery in the table 1 under the correct situation of capacity configuration, after discharge in 120 minutes, the theoretical voltage of battery should drop to 47.8V, uses said method to calculate absolute value error and is 1.6V, continuing along with discharge time as can be known, absolute value error increases, therefore, and the capacity mistake of the current configuration of battery.
Further, draw after absolute value error do not meet default rule in judgement, this method can also comprise:
Judge that whether the current discharge time of above-mentioned battery is greater than default discharge time N;
If not, the rated capacity configuration error of battery then;
If, judge then whether the absolute value error when N-1 time before the N time discharge of this battery discharged all meets default rule, if all meet default rule, then described battery is nature consumption, otherwise, judge the rated capacity mistake of the current configuration of described battery.
Need to prove, the computing method of the absolute value error when discharging for N-1 time before above-mentioned repeat no more, wherein here with the method described in the step 201-203, N is default discharge time, can be by obtaining in the empirical data to the measurement of consumption naturally of battery.
Step 204, the rated capacity of the current configuration of battery is revised.
Further, capacity configuration to battery is revised, specifically comprise: obtain in above-mentioned mapping, during through identical discharge time and the rated capacity of the pairing battery of the immediate theoretical voltage of virtual voltage of battery, during discharge time that above-mentioned process is identical and the rated capacity of the pairing battery of the immediate theoretical voltage of virtual voltage of battery reconfigure as the rated capacity of current battery.
The embodiment of the invention is by when battery carries out discharge operation, measure and write down battery at the virtual voltage of difference during discharge time, and compare with the theoretical voltage during through different discharge time under the rated capacity of current configuration and discharge current, draw absolute value error, whether the rated capacity of judging the current configuration of battery according to absolute value error mistake, use this method that the rated capacity configuration of battery is detected, can prevent because of the rated capacity configuration error with battery produces the residual capacity of battery is detected and the calculating of the life prediction of battery produces problem than large deviation, prevention because of the rated capacity configuration error of battery produce to discharging and recharging the problem of controlling and then influencing the life-span of battery.
