Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Present applicant proposes a kind of method that battery is carried out automatic combo, refer to Fig. 1, it include step S01~ S15, is specifically described below.
Discharge data acquisition step S01, adopt for carrying out the discharge data of battery by each battery is equipped with one Multiple loops are treated the battery timing of combo and carry out discharge data collection, described electric discharge the most simultaneously by the module of collection Data include current acquisition time, electric current and voltage.It should be noted that the battery that same batch is produced, typically The battery of same model can be probabilistically assigned into several loops, and each loop includes the battery of the series connection of equal amount.On The module that face gathers for discharge data, can be just to be installed in each battery in cell production process, it is also possible to be at electricity Before pond carries out combo, just it is installed in each battery.Traditional discharge data acquisition method, is usually artificial timing and is acquired, Such as gathered once every 10 minutes, in 1 minute, the discharge data of each battery on the same circuit all gathered complete every time, It is contemplated that the discharge data so collected, one is that data volume is less, and such as discharge process continues 8 hours, then altogether Only acquire 48 secondary data;Two is the error that manual measurement time difference is brought, and i.e. with the data once gathered, some of them are not Collecting at synchronization, there is the time difference of a manual measurement centre.And the application is by being equipped with each battery For carrying out the module that the discharge data of battery gathers, can accomplish multiple loops are treated the battery timing of combo and every for one Secondary carry out discharge data collection the most simultaneously, the module of the discharge data collection on the most each battery be configured to every 3 seconds with Time gather a discharge data, if so discharge process continues 8 hours, the most altogether acquire 9600 secondary data, the artificial collection of ratio The data arrived are much more, and the data the most every time gathered have not timed out difference, and this is for the discharge count of each battery of the same circuit According to being even more important.Traditional scheme then cannot gather the biggest data volume.
Discharge data preserves step S03, the discharge data gathered is saved in the database table specified.
In order to make the discharge data more reference significance in database table, in one embodiment, it is also possible to carry out abnormal number According to filtration step S05, the abnormal data in database table is deleted.Such as, the electric current number of a certain acquisition time in a battery According to for 65535A, hence it is evident that be far longer than the current data that acquisition time before and after it collected, then can be by this electric current number According to, or the whole discharge data collected this acquisition time delete from database table.
Data fit procedure S07, for each battery, carry out discharge characteristic curve matching according to its discharge data, with Obtain the sart point in time of electric discharge, end time point and discharge capacity.Owing to step S01 all having collected data to each battery The discharge data that density is the biggest, therefore can be precisely determined the sart point in time of each battery discharge, end time point, and The discharge capacity of each battery can be precisely calculated.And traditional artificial acquisition method, due to putting that each battery is collected The density of electricity data is the least, and the sart point in time of each battery discharge, end time point therefore cannot be precisely determined, the most also The discharge capacity of each battery cannot be precisely calculated, i.e. the least due to the density of discharge data, so according to these density very The sart point in time of the electric discharge that little discharge data obtains, end time point and discharge capacity, it is impossible to the true feelings reflecting battery Condition, reference significance is little, and the most traditional method for group matching never considered that use discharge capacity relation, to carry out combo, and was Using discharge voltage relation to carry out combo, but the voltage data owing to gathering every time also has time difference, therefore this also can When causing gathering, the voltage of rear collected battery, voltage data degree less than normal is the deepest, and this also makes traditional combo every time Method combo is inaccurate.
In order to make next to be made into the service life of the battery of a group and performance more preferably, more meet the requirements, implement one In example, it is also possible to carry out battery screening step S09, filter out qualified and/or underproof electricity according to default screening conditions Pond, correspondingly, step ((such as the same circuit preferential combo step S11 and different circuit combo step S13)) afterwards is carried out It is all to use qualified battery to carry out combo during combo.In one embodiment, specifically, the screening conditions preset in step S09 For: filter out qualified and/or underproof battery according to an afterbody electric discharge duration threshold value preset and discharge capacity threshold value, when When the afterbody electric discharge duration of battery is more than discharge capacity threshold value more than afterbody electric discharge duration threshold value and discharge capacity, battery is determined For qualified battery, otherwise, battery is judged as underproof battery.Here afterbody electric discharge duration, refers to arrange the first electricity Pressure and the second voltage, the battery time needed for the first voltage is put into the second voltage be referred to as afterbody electric discharge duration, the first voltage and The size of the second voltage can arrange occurrence according to demand.
The same circuit preferential combo step S11, for each battery in every primary Ioops, by be in the same circuit each Battery carries out combo according to default combo condition, and the combo condition wherein preset includes the relation of discharge capacity between battery.? When carrying out battery combo, preferentially the battery in the same circuit is carried out combo, this is because the battery in the same circuit is owing to being Series relationship, therefore electric current is identical, when so the discharge data between them compares, just has more comparability.
In a preferred embodiment, refer to Fig. 2, the flow process of the above-mentioned combo condition preset include step P01~ P15, is specifically described below.
It is the integer more than 1 that P01, the quantity of every Battery pack are set to N, N.N can be arranged specifically according to the actual requirements Value, such as, if having 16 batteries, then N can be set to 4, every Battery pack includes 4 batteries in each loop.
P03, battery is ranked up from high to low according to discharge capacity.
P05, start combo from the battery that discharge capacity is the highest, carry out step P07, it is judged that currently after this battery whether Also having N-1 battery, if not having, then carrying out step P09, it is determined that currently this battery and the failure of all combos of battery behind; If having, carry out step P11, the discharge capacity of this battery current with ensuing N-1 battery is compared two-by-two.
When in this N number of battery, the difference of the discharge capacity of any two battery is both less than a discharge capacity difference limen value preset Time, carry out step P13, it is determined that this N number of battery combo success, be configured to one group.And do not carry out combo from remaining Battery in the highest battery of discharge capacity restart combo, i.e. the electric discharge in the remaining battery not carrying out combo is held Measure the highest battery, again proceed by combo from step P07, certainly, if the remaining battery not carrying out combo does not exists, then Directly terminate.
When in this N number of battery, the difference of the discharge capacity of any two battery is not that the most described default discharge capacity is poor During threshold value, carry out step P15, it is determined that above-mentioned this battery combo failure current, then from the next one of this battery current Battery restarts combo, i.e. starts the next battery of this battery current, again proceeds by combo from step P07.
Give an example, refer to Fig. 3, each loop has 16 batteries, it is assumed that for primary Ioops, in these 16 batteries Having 6 batteries is defective battery, it is therefore desirable to 10 batteries in this primary Ioops are first carried out the combo between the same circuit.No Harm makes N be arranged to 4, is ranked up from high to low according to discharge capacity by the battery that 10 qualified, is wherein numbered 1 in figure Battery, its discharge capacity is the highest, is numbered the battery of 10, and its discharge capacity is minimum.
From the beginning of the battery being numbered 1, it is judged that whether have 4-1=3 battery after it, display, there are 3 electricity after it Pond, is i.e. numbered the battery of 2,3,4.It is numbered 1~4 these 4 batteries discharge capacities two-by-two to compare, when these 4 batteries During the discharge capacity difference limen value that the difference of the discharge capacity of middle any two battery is both less than preset, then these 4 battery combos become Merit, is i.e. numbered 1~4 these 4 batteries and is configured to one group.Next with regard to putting from the remaining battery not carrying out combo again The battery that capacitance is the highest restarts combo, i.e. from the beginning of the battery being numbered 5, joins according to the battery being numbered 1 before The method of group carries out combo, the most first judges to be numbered after the battery of 5 either with or without 3 batteries, if having, then compare be numbered 5~ The battery of 8 discharge capacity between any two is to carry out combo.Assume to be numbered the battery combo again success of 5~8, be configured to one Group, then start from the battery being numbered 9 again, carries out combo according to above-mentioned battery grouping method, now because of label Be there is no 3 batteries after the battery of 9, be only numbered 10 these batteries, therefore, it is determined that the battery that current index is 9 and it After all battery combos failure, be i.e. numbered 9,10 the two battery combos failure.So here it is situation one in Fig. 3, The battery being numbered 1~4 is made into one group, and the battery being numbered 5~8 is made into one group, is numbered the battery combo failure of 9,10.
Alternatively possible situation, from the beginning of the battery being numbered 1, has first judged have 3 batteries, i.e. labels after it It it is the battery of 2,3,4.It is numbered 1~4 these 4 batteries discharge capacities two-by-two to compare, if now when these 4 batteries are appointed When the difference of discharge capacity of two batteries of meaning is not the discharge capacity difference limen value both less than preset, it means that be numbered 1~4 this 4 batteries can not be made into one group, now judges this battery current, is i.e. numbered the battery combo failure of 1, then from current this The next battery of individual battery is i.e. numbered the battery of 2 and restarts combo, the most first judges that the battery being numbered 2 is followed by No have 3 batteries, is judged as that the battery of 2 is also numbered 3~10 these 8 batteries in example, then obviously, is numbered the electricity of 2 There are 3 batteries after pond, judge the battery being numbered 2 and 3 batteries thereafter the most again, be i.e. numbered the battery of 2~5 two-by-two Between discharge capacity, if the discharge capacity that in these 4 batteries, the difference of the discharge capacity of any two battery is both less than preset is poor During threshold value, then these 4 battery combo successes, i.e. it is numbered 2~5 these 4 batteries and is configured to one group, with that from being numbered The battery of 6 starts and carries out combo, if combo success the most again, is i.e. numbered the battery combo success of 6~9, is configured to One group, it follows that start combo from the battery being numbered 10 again, there is no the most thereafter 3 batteries, be then numbered the battery quilt of 10 It is judged to combo failure.So here it is situation two in Fig. 3, the battery being numbered 2~5 is made into one group, is numbered 6~9 Battery is made into one group, is numbered the battery combo failure of 1,10.Certainly these 10 batteries actually have multiple combo situation, above Two kinds of situations be intended merely to coordinate explanation understand in Fig. 2 preset combo condition flow process in step P01~P15.
Different circuit combo step S13, in each loop according to the battery that default combo condition combo is failed, by this A little batteries carry out combo according to above-mentioned default combo condition.The application first carries out combo to the battery being in the same circuit, this Sample, has some loops to there may be the battery that combo is failed, then again to the failed battery of combo in each loop from each other Carry out combo, namely across loop combo.Step S13 carries out combo from each other to the battery that combo in each loop is failed The combo condition used and method, as step S11.Such as, after step S11, combo failure in each loop A total of 12 of battery, then with regard to first carrying out step P03, the discharge capacity of these 12 batteries is ranked up from high to low, The most just carry out combo according to step P05~P15.Certainly, combo in step s 13, the number of batteries often organized is and step The number of batteries often organized arranged in S11 is the same.
After the battery that combo is failed in different circuit combo step S13 is to each loop carries out combo, it is also possible to meeting The battery that some combos are failed occurs, therefore, in one embodiment, after different circuit combo step S13, also carries out difference Batch combo step S15, produces, by this batch, the battery that in different circuit combo step S13 in cell process, combo is failed, It is put into again in different circuit combo step S13 in lower batch production cell process and carries out combo.Therefore, it practice, this batch Different circuit combo step S13, have this batch battery that the same circuit combo is failed in step s 11 except receiving, also May also have received the last batch battery that combo is failed in different circuit combo step S13, namely the difference of this batch is returned Road combo step S13, in one embodiment, is to this batch electricity that combo is failed in the same circuit preferential combo step S11 Pond and the last batch battery that combo is failed in different circuit combo step S13 carry out combo, and such as, this batch is at same time The battery that in preferential combo step S11 of road, combo is failed has 12, and last batch is combo in different circuit combo step S13 Failed battery has 3, then this 12+3=15 battery is joined in different circuit combo step S13 by this batch exactly Group.
The method that battery is carried out automatic combo of the application, can not only carry out combo to the battery being in the same circuit, The battery being in different circuit or different batches can also be carried out combo, reason is: because in discharge data acquisition step S01 Each battery all can be collected the discharge data that density is sufficiently large, thus the discharge capacity calculated afterwards is the most smart Really, the true discharge capacity of battery can be reflected the most truly, and different circuit or the battery of batch, even if gathering electric discharge Electric current during data is different, but owing to the discharge capacity of different batteries the most still has the highest comparability, Therefore combo can be carried out, certainly, owing to each battery in the same circuit is being adopted according to the discharge capacity relation of different batteries Electric current during collection discharge data is the same, in this case, and the discharge capacity of each battery in the same circuit calculated, the most more There is comparability, first preferentially should close according to the discharge capacity of different batteries in tying up to the same circuit and join between each battery Group, carries out battery failed for combo in the same circuit carrying out combo across loop or across batch the most again.And in traditional scheme, first The discharge data the lowest owing to can only collect density, the discharge capacity therefore calculated according to such data is the most inaccurate Really, it is impossible to reflect the true discharge capacity of battery, even having the biggest 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, and discharge voltage the most from each other just has certain comparability, can carry out combo according to discharge voltage, The battery of different circuit is different due to electric current, then the comparability of discharge voltage is the lowest, so between different circuit Battery cannot carry out combo according to discharge voltage.
Refer to Fig. 4, the application also proposed a kind of device that battery carries out automatic combo, and it includes multiple discharge count Module 03, data fitting module 07, the same circuit preferential combo module 11, difference time is preserved according to acquisition module 01, discharge data Road combo module 13 and combo condition configuration module 17, in one embodiment, it is also possible to include abnormal data filtering module 05, electricity At least one module in pond screening module 09 and different batches combo module 15, is specifically described below.
