[0002] As the only power source for pure electric vehicles, the performance of the power battery directly affects the performance of the entire vehicle. The power battery is composed of cells connected in series and parallel. The performance of the entire vehicle still depends on the performance of the cells, so the battery management system needs to monitor the cell voltage at all times. When a string or several strings of cells are abnormal, an alarm signal needs to be issued to remind the user that maintenance is required.
[0003] During the product development process, it is often encountered that the cell serial number displayed by the battery management system is inconsistent with the actual monitored cell serial number, which interferes with troubleshooting. At present, during the product development stage, it is necessary to verify whether the cell serial number displayed by the battery management system is consistent with the actual monitored cell serial number. There are two commonly used methods:
[0004] A terminal withdrawal method, which requires the terminal of each single acquisition loop to be withdrawn from the connector, is very troublesome to operate and requires the use of special tools and professional personnel, which is inefficient, and after the test is completed, the wiring harness is also damaged and cannot be used;
[0005] Another method is to design a terminal block, crimp OT terminals at both ends of the wiring harness, use bolts to fix the OT terminals to the terminal block, and disconnect the single-cell collection circuit by removing the OT terminals.
[0006] The above two methods are both complicated to operate and have low efficiency. Utility Model Content

[0035] In order to achieve connection with the battery cell 12, the battery system cell serial number consistency detection tool of this embodiment also includes a battery system 11, the battery system 11 includes a plurality of cells 12, each of which is connected to a second module connector, the first module connector 3 is connected to the second module connector, and the first module connector 3 corresponds to the second module connector model. In this way, the plurality of battery cells 12 can be connected to the first tool 1 using the first module connector 3 and the second module connector.
[0036] It also includes a BMS13, on which a plurality of second BMS connectors are arranged, the first BMS connector 6 is connected to the second BMS13 connector, and the first BMS connector 6 corresponds to the second BMS13 connector model.

[0037] In order to facilitate the limiting and releasing of the first single-hole connector 5 and the second single-hole connector 8, the first single-hole connector 5 and the second single-hole connector 8 are plugged and fixed to each other. In this embodiment, the first single-hole connector 5 is a male plug connector, and the second single-hole connector 8 is a female plug connector, which can achieve fast plug-in, thereby achieving fast and safe switching of the single-cell 12 acquisition circuit.
[0038] In this embodiment, a plurality of first module connectors 3 constitute a module connector assembly 19; a first single-hole connector 5 and a second single-hole connector 8 that are plugged and fixed to each other constitute a single-hole plug-in connector assembly 20; and a plurality of first BMS connectors 6 constitute a BMS connector assembly 21.

[0039] like Figure 4 As shown, the connection circuit formed is specifically described as follows:
[0040] Assume that a plurality of cells 12 are numbered C1, C2 ... Cn-1, Cn, and C1, C2 ... Cn-1, Cn are connected in series to form a battery system 11:
[0041] Each cell Cn is connected from the positive terminal to the first module connector 3, and the first module connector 3 is connected to the first single-hole connector 5 through the first wire 4;
[0042] Each second BMS connector of the BMS 13 is connected to a corresponding first BMS connector 6, and the first BMS connector 6 is connected to the second single-hole connector 8 via a second wire 7;
[0043] Each corresponding first single-hole connector 5 and second single-hole connector 8 is equivalent to a switch, that is, Figure 4 Kn in;
[0044] A voltmeter 18 is connected in series between every two adjacent second BMS connectors on the BMS 13 .
[0045] The first tooling 1 and the second tooling 2 are connected through the first single-hole connector 5 and the second single-hole connector 8 to connect the monomer 12 collection circuit; by plugging and unplugging the first single-hole connector 5 and the second single-hole connector 8, the monomer 12 collection circuit is quickly and safely turned on and off, and the battery management system BMS13 determines whether the monomer 12 number displayed by the battery management system BMS13 is consistent with the actual collected monomer 12 number based on the voltage collected by the voltmeter 18.
[0046] like Figure 2 As shown, a first code tube 14 is provided on the first wire 4 , and a first wire marker 15 is provided on the first code tube 14 .
[0047] like Figure 3 As shown, a second code tube 16 is provided on the second wire 7 , and a second wire marker 17 is provided on the second code tube 16 .
[0048] In this embodiment, the first wire identifier 15 is printed on the first code tube 14, and the first wire identifier 15 is used to define the function of each first wire 4, and the first wire 4 connects the first module connector 3 with the first single-hole connector 5; the second wire identifier 17 is printed on the second code tube 16, and the second wire 7 connects the second BMS13 connector with the first BMS connector 6.
[0049] Working principle:
[0050] like Figure 4 As shown, the H1 male connector in the first single-hole connector 5 and the H1 female connector in the second single-hole connector 8 are a pair of inter-plug connectors. The corresponding working principle of this pair of connectors is Figure 4 The middle switch K1, H1 male connector and H1 female connector are on the first string of monomer 12 collection circuit. When the H1 male connector is separated from the H1 female connector, the switch K1 is disconnected. At this time, the voltage of the first string of monomers 12 and the voltage of the second string of monomers 12 corresponding to the battery management system are abnormal, indicating that the monomer 12 number displayed by the battery management system is consistent with the actual collected monomer 12 number, otherwise it is inconsistent;
[0051] The H2 male connector and the H2 female connector are on the second string of monomer 12 collection loop. When the H2 male connector and the H2 female connector are separated, the switch K2 is disconnected. At this time, the voltage of the second string of monomers 12 and the voltage of the third string of monomers 12 corresponding to the battery management system are abnormal, indicating that the monomer 12 number displayed by the battery management system is consistent with the actual collected monomer 12 number, otherwise they are inconsistent;
[0052] Similarly, the male connector in the first single-hole connector 5 and the female connector in the second single-hole connector 8 are separated in turn, and the abnormal string number of the single cell 12 is observed to be consistent with the separation circuit, and it is determined whether the single cell 12 number displayed by the entire battery management system is consistent with the actual collected single cell 12 number.
[0053] At the same time, each hole of the first module connector 3 in the first tooling 1 and the first BMS connector 6 in the second tooling 2 is matched with a wire when the tooling is designed. Even if different projects use the same type of connector, the tooling can be used with different definitions of the single 12 collection pins. You only need to change the wire identification according to the actual collection situation of the project, for example Figure 5 The tooling connection method shown is similar to Figure 6 The tooling connection method shown.
[0054] The tooling in this embodiment uses a single-hole connector to quickly and safely connect and disconnect the monomer 12 collection circuit, and diagnose whether the monomer 12 number displayed by the battery management system is consistent with the actual collected monomer 12 number. At the same time, this tooling can be designed in a simple form, only adapted to one project, or in a more complex form, adapted to more projects, and this tooling can be reused.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
