Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment one
A kind of open Address Recognition method of the present embodiment one, the method is for carrying out Address Recognition to the set of cells in battery bag, and described battery bag includes M set of cells, and M is the natural number not less than 1.
With reference to Fig. 1, described method includes:
S101: according to address wire order set in advance, obtains the level state of each address wire in set of cells address wire wire harness, obtains level state sequence, wherein, the corresponding group address line wire harness of each set of cells.
As in figure 2 it is shown, set of cells 1 corresponding address line wire harness 1, set of cells 2 corresponding address line wire harness 2 ..., set of cells M corresponding address line wire harness M, every group address line wire harness includes N bar address wire.The most corresponding unique numbering of each bar address wire, in Fig. 2, address wire wire harness 1, address wire wire harness 2 ... the N bar address wire that address wire wire harness n each includes distinguishes reference numeral A0, A1, A2 from right to left ... An.
Described level state includes high level and low level.
The value of the address number of lines N comprised in every group address line wire harness depends on the size of the set of cells number M comprised in battery bag, specifically, the value of N realizes carrying out M set of cells respectively address mark can be put in order by the difference using N bar address wire low and high level state, enable each set of cells to have unique ID (Identity, identity) address to be as the criterion.
Such as, assume that battery bag includes 4 set of cells altogether: set of cells 1, set of cells 2 ... set of cells 4, then the value of N is: N >=2, with N=2, as a example by the most every group address line wire harness includes two address wires A0, A1, then A1, A0 can pass through 4 groups of level states: high-low, low-high, high-high and low-low 4 set of cells are carried out address differentiation.
This step specifically obtains the level state of each address wire in set of cells address wire wire harness according to the order of address wire numbering descending, obtain the level state sequence of set of cells, such as, for the N bar wire harness of set of cells in Fig. 21, this step presses An, A (n-1) ... the order of A1 obtains the level state of each address wire.
S102: based on the corresponding relation between level state set in advance and data encoding, each level state in described level state sequence is converted to corresponding data encoding.
The present embodiment has pre-established high and low two kinds of corresponding relations between level state and data encoding, and wherein, the data encoding that high level is corresponding is numeral " 1 ", and data encoding corresponding to low level is digital " 0 ".
On this basis, each address wire level state that previous step is obtained by this step is changed, and is converted to " 1 " by corresponding high level, and low transition is " 0 ".Such as, assume a group address line wire harness includes A4, A3, A2, A1, A0 these 5 address wires altogether, its level state is respectively as follows: high and low, high, high and low, then this step transfers high level corresponding to A4, A2, A1 to " 1 " respectively, is " 0 " by low transition corresponding to A3, A0.
S103: based on the relative rank of each level state in described level state sequence, obtains the encoded data sequence being made up of data encoding each described, and is identified as the address of described set of cells by described encoded data sequence.
After the level state of address wire each in address wire wire harness is converted into corresponding data encoding, this step is specifically according to the relative rank of each level state in corresponding level state sequence, obtain corresponding encoded data sequence, and use described encoded data sequence as the ID address of respective battery group, described set of cells is identified.
Such as, the low and high level status switch that in above example, these 5 address wires of A4, A3, A2, A1, A0 are corresponding is: high-low-high-height-low, then the encoded data sequence of its correspondence is 10110, thus the ID address of described set of cells is: 10110.
In detail below as a example by the application to the present invention of the battery management controller assembly, describe the present invention.
As shown in Figure 2, battery bag includes M set of cells: set of cells 1-set of cells M, and it is respectively configured address wire wire harness 1-address wire wire harness M for each set of cells, each address wire wire harness includes An-A0 N bar address wire altogether, and each address wire wire harness is by forming set of cells and the geocoding of corresponding point of plate thereof different connection of its address wire.
Correspondingly, battery management controller assembly includes a mainboard, and M point plate, each point of plate is by CAN (Controller Area Network, controller local area network) bus realize and mainboard between data communication, each point of plate configuration one is integrated with the present invention and processes the single-chip microcomputer of logic, plate is divided to map one by one with set of cells, specifically, plate is divided to be connected with address wire wire harness and each battery cell of set of cells by connector, and the N bar address wire in address wire wire harness is drawn to N number of pin of described single-chip microcomputer, divide intralaminar part that by pull-up resistor, each bar address wire is pulled to high level, when the address wire being used for encoding in set of cells wire harness is connected to the minimum voltage end of this set of cells, the level of appropriate address line is low；In set of cells wire harness when address wire unsettled (being not connected to) of coding, the level of appropriate address line is high.
Single-chip microcomputer gathers the low and high level state alignment order of each bar address wire An-A0 by its pin identification, and utilizing its process logic being internally integrated that the low and high level sequence of collection is converted to corresponding binary address coding, this binary address is encoded as its unique CAN communication ID by point plate.
On this basis, each point of plate gathers in respective battery group the data such as the running voltage of each monomer, operating current, temperature, and the data of collection are uploaded to mainboard by CAN, the detection data that follow-up mainboard utilizes point plate to upload calculate the dump energy of battery in respective battery group, the achievement datas such as battery health degree, with ensure electrokinetic cell wrap in its regulation characteristic range in properly functioning.Once detect that abnormal information, battery management controller assembly can be cut off electrokinetic cell bag and be connected with the high pressure of electric automobile, to ensure the personal safety of passenger.
The present invention program can realize the exchange between point plate, after changing point plate, address wire is unchanged, the ID address of set of cells is unchanged, and point plate after replacing is capable of identify that the address wire coding of the new set of cells being connected, and as unique ID of point plate CAN communication, do not result in CAN data entanglement.
From above scheme, Address Recognition method disclosed by the invention, by identifying the level state sequence of address wire in set of cells address wire wire harness, and by level state sequence is converted to corresponding encoded data sequence, obtain the address mark of described set of cells.Visible, during the concrete application present invention, directly the process logic of the inventive method is integrated in each point of plate, each point of plate reads the address wire level state sequence of respective battery group, and the encoded data sequence corresponding to the level state sequence that will read is as its point of plate address, so that it is identified by mainboard, without each point of plate being carried out difference design, the state of each point of plate is identical, it is easy to produce and management, and can be interchangeable between each point of plate, improve the flexibility ratio of system, reduce maintenance difficulties and the maintenance cost of battery bag simultaneously.
Embodiment two
The present embodiment two continues to expand the scheme of embodiment one, and with reference to Fig. 3, described method also includes:
S104: described address mark is carried out abnormity diagnosis.
Wherein, with reference to Fig. 4, described step S104 specifically includes following steps:
S401: obtain the different address mark corresponding to M set of cells of battery bag.
Specifically, the abnormity diagnosis work of address mark is carried out by mainboard.Mainboard, by carrying out CAN communication between M point plate, receives M the CAN data dividing plate to send and records its different ID number.
S402: judging whether invalid address mark, if the determination result is YES, the most described invalid set of cells address wire corresponding to the mark of address is abnormal, and otherwise, if judged result is no, the address wire of the most each set of cells is normal.
This step increases the validation checking function to point plate ID.Specifically, encoding the number of " 0 " in the prespecified effective ID address of the present embodiment, whether follow-up mainboard meets prespecified number by the number encoding " 0 " in detection point plate ID address, and the ID address sentencing section board is the most effective.
Specifically, in the present embodiment, effective ID address of regulation is as follows:
When the address number of lines N of set of cells is even number, the ID address that number is N/2 of coding " 0 "；
When the address number of lines N of set of cells is odd number, the ID address that number is (N-1)/2 of coding " 0 ".
Based on the above-mentioned regulation that effective ID is made, mainboard judges in each point of plate ID obtained, whether the low level number i.e. number of " 0 " is N/2 (N is even number) or (N-1)/2 (N is odd number), if the number of " 0 " is N/2 or (N-1)/2, then dividing plate ID to meet regulation, corresponding set of cells address wire is without exception；Otherwise, address wire is abnormal, need to overhaul the address wire of respective battery group, it is ensured that its ID address is effective.
Such as, if point plate ID that mainboard obtains is 00001, then this point of plate ID is that invalid ID is (when address number of lines is 5, the number of 0 should be 2), thus need technical staff that the address wire of respective battery group is overhauled, the level state of its address wire is reset so that it is in corresponding geocoding, the number of 0 is 2.
Based on the above-mentioned regulation being made effective ID, address number of lines N included in the address wire wire harness of each set of cells needs to meet following condition, to realize carrying out M set of cells unique address mark:
When N is even number,
When N is odd number,
S403: judge whether total number of different address marks is less than M, if the determination result is YES, then corresponding different set of cells address wire wire harness states are overlapping；Otherwise, if judged result is no, the address wire wire harness state of each set of cells is normal, non-overlapping.
In this step, the communication id of each point of plate is collected by mainboard, and judge that whether the ID number of different ID is less than M, if obtaining M different ID altogether, then characterize the situation that each point of plate ID does not duplicates, the each point of all corresponding unique ID of plate, thus the address wire wire harness state of each set of cells is normal, non-overlapping.
If total number of different ID is not up to M, then characterize and there is the situation that point plate ID repeats, and then there is the situation that respective battery group wire harness state is overlapping, such as, if the ID of point plate 1 and point plate 2 is 10110, then corresponding set of cells 1 is identical with the level state of set of cells 2 address wire wire harness, thus corresponding set of cells wire harness need to be overhauled, the situation overlapping to get rid of set of cells wire harness state, the geocoding different from other set of cells wire harness can be realized, such as when set of cells 1 is identical with the level state of set of cells 2 address wire wire harness, the address wire wire harness of maintenance set of cells 2, change putting in order of its address wire low and high level, it is made to put in order different from the address wire level of set of cells 1, ensure that the address wire level of each set of cells of itself and other puts in order different simultaneously.
It follows that provide a concrete application example of the present invention.
As it is shown in figure 5, the system of this example includes battery bag, mainboard, 10 points of plates and 10 Battery pack group wire harness (i.e. address wire wire harness), battery bag includes 10 set of cells, according to formulaOrCalculate and every Battery pack group wire harness at least needs to comprise 5 address wires, wherein, have 2 address wires need to be connected to the minimum voltage end of respective battery group to produce low level.
The set of cells in advance 10 set of cells being carried out code Design, specific coding and correspondence sees table 1.
Table 1
Afterwards, according to the code Design of table 1, the address wire of each set of cells is carried out corresponding low and high level configuration.Wherein, by 2 minimum voltage ends being connected to respective battery group corresponding in 5 address wire A4 to A0, such as, as shown in Figure 5, the set of cells wire harness that No. 1 set of cells is corresponding, two address wires of its A4, A3 are connected to the minimum voltage end of No. 1 set of cells, and three address wires of A2 to A0 are unsettled not to be connect；No. 2 set of cells corresponding set of cells wire harness, two address wires of its A4, A2 are connected to the minimum voltage end of No. 2 set of cells, and tri-address wires of A3, A1, A0 are unsettled not to be connect；The rest may be inferred.
When the address wire dividing plate to read is encoded to 00111, the address wire low level number of this point of plate is 2, and the fault diagnosis result of mainboard is that address wire is normal, thus CAN communication ID of this point of plate is 0x07, corresponding No. 1 point of plate；Point plate reads address wire when being encoded to 01011, and low level number corresponding to its address wire is 2, and the fault diagnosis result of mainboard is that address wire is normal, and CAN communication ID of this point of plate is 0x0B, is No. 2 points of plates；The rest may be inferred.
When the address wire low level number that point plate reads not is 2, the fault diagnosis result of mainboard is address wire exception and reports fault.
When mainboard detects different ID numbers less than 10, the wire harness state of corresponding different set of cells repeats, mainboard report fault.
