Specific embodiment
The application is described in further detail below by specific embodiment combination attached drawing.
Present applicant proposes the methods that a kind of pair of battery carries out automatic combo, please refer to Fig. 1 comprising and step S01~
S15 is specifically described below.
Discharge data acquisition step S01, it is adopted by being equipped with one to each battery for carrying out the discharge data of battery
The module of collection, to carry out to the battery timing of combo and simultaneously discharge data acquisition, the electric discharge every time to multiple circuits
Data include current acquisition time, electric current and voltage.It should be noted that for the battery that same batch is produced, generally
The battery of same model can be probabilistically assigned into several circuits, and each circuit includes the concatenated battery of equal amount.On
Face is used for the module of discharge data acquisition, can be and is just installed in each battery in cell production process, is also possible in electricity
Before pond carries out combo, it is just installed in each battery.Traditional discharge data acquisition method is usually manually periodically acquired,
Such as it is primary every acquisition in 10 minutes, the discharge data of each battery on the same circuit is all acquired in 1 minute finish every time,
It is contemplated that the discharge data collected in this way, first is that data volume is smaller, for example discharge process continues 8 hours, then in total
Only acquire 48 data；Second is that manual measurement time difference bring error, i.e., with the data of one acquisition, some of them are not
It is, the intermediate time difference that has a manual measurement collected in synchronization.And the application is by being equipped with each battery
The module of one discharge data acquisition for carrying out battery can accomplish to multiple circuits to the battery timing of combo and every
The secondary module for all carrying out the discharge data acquisition in discharge data acquisition, such as each battery simultaneously is configured to same every 3 seconds
When acquire a discharge data and if discharge process continues 8 hours in this way 9600 data acquired in total, than manually acquiring
The data arrived are much more, while the data acquired every time have no time yet difference, this discharge count for each battery of the same circuit
According to being even more important.And traditional scheme can not then acquire so big data volume.
Discharge data saves step S03, discharge data collected is saved in the table of specified data library.
In order to make the discharge data in database table have more reference significance, in one embodiment, abnormal number can also be carried out
According to filtration step S05, the abnormal data in database table is deleted.For example, in a battery a certain acquisition time electric current number
According to for 65535A, hence it is evident that be far longer than the collected current data of its front and back acquisition time institute, then it can be by this electric current number
According to, or the collected whole discharge datas of this acquisition time institute are deleted from database table.
Data fit procedure S07, for each battery, discharge characteristic curve fitting is carried out according to its discharge data, with
Point, end time point and discharge capacity at the beginning of being discharged.Due to all having collected data to each battery in step S01
The very big discharge data of density, therefore point, end time point at the beginning of each battery discharge can be precisely determined, and
The discharge capacity of each battery can be precisely calculated.And traditional artificial acquisition method, it is put since each battery institute is collected
The density very little of electric data, therefore point, end time point at the beginning of each battery discharge can not be precisely determined, while
The discharge capacity of each battery can not be precisely calculated, i.e., due to the density very little of discharge data, so very according to these density
Point, end time point and discharge capacity, can not really reflect the feelings of battery at the beginning of the electric discharge that small discharge data obtains
Condition, reference significance is little, therefore traditional method for group matching never considered to carry out combo using discharge capacity relationship, and is
Combo is carried out using discharge voltage relationship, but since the voltage data acquired every time also has the time difference, this also can
When causing to acquire every time, the voltage of more collected battery, voltage data degree less than normal is deeper, this is but also traditional combo
Method combo inaccuracy.
Service life and performance in order to make next to be made into one group of battery are more preferable, more meet the requirements, and implement one
In example, battery screening step S09 can also be carried out, qualified and/or underproof electricity is filtered out according to preset screening conditions
Pond, correspondingly, later the step of ((such as the same circuit preferential combo step S11 and different circuit combo step S13)) carry out
It is all to carry out combo using qualified battery when combo.In one embodiment, specifically, preset screening conditions in step S09
Are as follows: qualified and/or underproof battery is filtered out according to a preset tail portion electric discharge duration threshold value and discharge capacity threshold value, when
When the tail portion electric discharge duration of battery is greater than tail portion electric discharge duration threshold value and discharge capacity greater than discharge capacity threshold value, battery is determined
For qualified battery, otherwise, battery is judged as underproof battery.Here tail portion electric discharge duration refers to the first electricity of setting
Pressure and second voltage, battery from first voltage be put into second voltage needed for the time be known as tail portion electric discharge duration, first voltage and
Can occurrence be arranged according to demand in the size of second voltage.
The preferential combo step S11 of the same circuit, for each battery in every primary Ioops, will be each in the same circuit
Battery carries out combo according to preset combo condition, wherein preset combo condition includes the relationship of discharge capacity between battery.?
When carrying out battery combo, combo preferentially is carried out to the battery in the same circuit, this is because the battery in the same circuit is due to being
Series relationship, therefore electric current is identical, when the discharge data between them is compared in this way, just has more comparativity.
In a preferred embodiment, referring to figure 2., the process of above-mentioned preset combo condition include step P01~
P15 is specifically described below.
P01, every group of battery quantity be set as N, N is the integer greater than 1.N can be arranged specifically according to actual needs
Value, for example, then 4 can be set by N, including 4 batteries by every group of battery if sharing 16 batteries in each circuit.
P03, battery is ranked up from high to low according to discharge capacity.
P05, the combo since the highest battery of discharge capacity carry out step P07, judge behind this current battery whether
There are also N-1 batteries, if not having, carry out step P09, determine that this current battery and its subsequent battery all combos fail；
If so, carrying out step P11, the discharge capacity of current this battery and next N-1 battery is compared two-by-two.
When the difference of the discharge capacity of any two battery in this N number of battery is both less than a preset discharge capacity difference threshold value
When, step P13 is carried out, this N number of battery combo success is determined, is configured to one group.And combo is not carried out from remaining
Battery in the highest battery of discharge capacity restart combo, i.e., the electric discharge in the remaining battery for not carrying out combo is held
Highest battery is measured, carries out combo since step P07 again, certainly, if the remaining battery for not carrying out combo is not present,
Directly terminate.
When the difference of the discharge capacity of any two battery in this N number of battery is not that the both less than described preset discharge capacity is poor
When threshold value, step P15 is carried out, determines above-mentioned this current battery combo failure, then from the next of this current battery
Battery restarts combo, i.e., starts to next battery of this current battery, carry out combo since step P07 again.
For example, referring to figure 3., 16 batteries are shared in each circuit, it is assumed that for primary Ioops, in this 16 batteries
Having 6 batteries is unqualified battery, it is therefore desirable to the combo first carrying out the same circuit to 10 batteries in this primary Ioops.No
Harm enables N be arranged to 4, is ranked up 10 qualified batteries from high to low according to discharge capacity in figure, wherein marked as 1
Battery, discharge capacity highest, the battery marked as 10, discharge capacity are minimum.
Since the battery marked as 1, judge whether there be 4-1=3 battery behind it, show, there are 3 electricity behind it
Pond, the i.e. battery marked as 2,3,4.Marked as 1~4, this discharge capacity of 4 batteries two-by-two is compared, when this 4 batteries
When the difference of the discharge capacity of middle any two battery is both less than preset discharge capacity difference threshold value, then this 4 batteries are with composition
Function, i.e., marked as 1~4, this 4 batteries are configured to one group.Next with regard to again from putting in the remaining battery for not carrying out combo
The highest battery of capacitance restarts combo, i.e., since the battery marked as 5, matches according to the battery marked as 1 before
The method of group carries out combo, i.e., first judges either with or without 3 batteries behind the battery marked as 5, compare again if having marked as 5~
The discharge capacity of 8 battery between any two is to carry out combo.Assuming that the battery combo success again marked as 5~8, is configured to one
Group, then again since the battery marked as 9, combo is carried out according to above-mentioned battery grouping method, at this time because of label
For after 9 battery without 3 batteries, only this battery marked as 10, therefore, it is determined that battery that current index is 9 and it
All battery combos failure afterwards, i.e., marked as 9,10, the two battery combos fail.So here it is the situation one in Fig. 3,
Battery marked as 1~4 is made into one group, and the battery marked as 5~8 is made into one group, the battery combo failure marked as 9,10.
Alternatively possible situation has first judged there is 3 batteries, i.e. label behind it since the battery marked as 1
For 2,3,4 battery.Marked as 1~4, this discharge capacity of 4 batteries two-by-two is compared, if at this time when in this 4 batteries
Anticipate two batteries discharge capacity difference be not both less than preset discharge capacity difference threshold value when, it means that marked as 1~4 this
4 batteries cannot be made into one group, determine this current battery at this time, i.e., the battery combo failure marked as 1, then from it is current this
Next battery of a battery is that the battery marked as 2 restarts combo, that is, first judges that the battery marked as 2 is followed by
It is no to have 3 batteries, it is judged as 2 battery also this 8 batteries marked as 3~10 in example, it is evident that, the electricity marked as 2
There are 3 batteries behind pond, then judges the battery marked as 2 with 3 batteries thereafter, the i.e. battery marked as 2~5 two-by-two again
Between discharge capacity, if to be both less than preset discharge capacity poor for the difference of the discharge capacity of any two battery in this 4 batteries
When threshold value, then this 4 battery combos success, i.e., marked as 2~5, this 4 batteries are configured to one group, with that from marked as
6 battery starts and carries out combo, if next combo success again, i.e., the battery combo success marked as 6~9, are configured as
One group, next, the combo since the battery marked as 10 again, at this time thereafter without 3 batteries, then the battery quilt marked as 10
It is determined as that combo fails.So here it is the situation two in Fig. 3, the battery marked as 2~5 is made into one group, marked as 6~9
Battery is made into one group, the battery combo failure marked as 1,10.Actually there are many combo situations for this certain 10 batteries, above
Two kinds of situations be intended merely to cooperation explanation and understand step P01~P15 in the process of the preset combo condition in Fig. 2.
Different circuit combo step S13, the battery for failing in each circuit according to preset combo condition combo, by this
A little batteries carry out combo according to above-mentioned preset combo condition.The application first carries out combo to the battery in the same circuit, this
Sample has some circuits to might have the battery of combo failure, then again from each other to the battery of combo failure in each circuit
Carry out combo, that is, across circuit combo.Combo is carried out from each other to the battery of combo failure in each circuit in step S13
In used combo condition and method, with step S11.For example, combo fails in each circuit after step S11
A total of 12, battery, then with regard to first carry out step P03, the discharge capacity of this 12 batteries is ranked up from high to low,
Combo just is carried out according to step P05~P15 later.Certainly, combo in step s 13, every group of number of batteries are and step
Every group of number of batteries being arranged in S11 is the same.
After battery of the different circuit combo step S13 to combo failure in each circuit carries out combo, it is also possible to meeting
There is the battery of some combo failures, therefore, in one embodiment, after different circuit combo step S13, also carries out different
This batch is produced the battery of combo failure in the different circuit combo step S13 in cell process by batch combo step S15,
Combo is carried out in the different circuit combo step S13 being put into lower batch production cell process again.Therefore, in fact, this batch
Different circuit combo step S13, in addition to receive have this batch in step s 11 the same circuit combo failure battery, also
The last batch battery of combo failure namely difference of this batch in different circuit combo step S13 may be also had received to return
Road combo step S13 is in one embodiment the electricity of the combo failure in the preferential combo step S11 of the same circuit to this batch
Pond and the last batch battery of combo failure in different circuit combo step S13 carry out combo, for example, this batch is at same time
The battery of combo failure shares 12 in the preferential combo step S11 in road, last batch combo in different circuit combo step S13
The battery of failure has 3, then this batch is exactly to match in different circuit combo step S13 to this 12+3=15 battery
Group.
The method for carrying out automatic combo to battery of the application can not only carry out combo to the battery in the same circuit,
Combo can also be carried out to the battery in different circuit or different batches, the reason is that: because in discharge data acquisition step S01
The sufficiently large discharge data of density can be all collected to each battery, thus calculated discharge capacity is also just very smart later
Really, the true discharge capacity of battery can be truly reflected out very much, and the battery of different circuit or batch, even if discharging in acquisition
Electric current when data is different, but since the discharge capacity of different batteries still has very high comparativity in this case,
Therefore combo can be carried out according to the discharge capacity relationship of different batteries, certainly, since each battery in the same circuit is being adopted
Electric current when collecting discharge data is the same, in this case, the discharge capacity of each battery in calculated the same circuit, and just more
It is comparable, should preferentially be matched between battery each in the same circuit according to the discharge capacity relationship of different batteries first
Group, the battery again by combo failure in the same circuit is carried out across circuit or across batch carry out combo later.And in traditional scheme, it is first
It is very inaccurate according to the calculated discharge capacity of such data first since the very low discharge data of density can only be collected
Really, it can not reflect the true discharge capacity of battery, or even have very big deviation, therefore traditional scheme never considered basis
Discharge capacity carries out combo, but carries out combo according to discharge voltage, in this case, the battery of the same circuit due to
Electric current is the same, therefore discharge voltage from each other just has certain comparativity, can carry out combo according to discharge voltage,
The battery of different circuit is since electric current is different, then the comparativity of discharge voltage is also just very low, so between different circuit
Battery can not carry out combo according to discharge voltage.
Referring to figure 4., the application also proposed the device that a kind of pair of battery carries out automatic combo comprising multiple discharge counts
According to acquisition module 01, discharge data preserving module 03, data fitting module 07, the preferential combo module 11 of the same circuit, different times
