[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0039] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In the description of this application, unless otherwise specified, "plurality" refers to two or more. "and / or" describes an association relationship between associated objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In addition, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0040] Those skilled in the art will appreciate that the drawings are merely schematic diagrams of exemplary embodiments and may not be to scale. The modules or processes in the drawings are not necessarily required to implement the present application and therefore cannot be used to limit the scope of protection of the present application.

[0041] It should be noted that in the drawings of the embodiments of the present application, an arrow marked X represents a first direction X, an arrow marked Y represents a second direction Y, and an arrow marked Z represents a third direction Z. The description of the present application introduces the first direction X, the second direction Y and the third direction Z for more clearly describing the structure and relative position relationship of the components in the sampling harness connecting device. In actual application, the first direction X, the second direction Y and the third direction Z can point to any direction in space. In some embodiments, in the sampling harness connecting device, the first direction X corresponds to the length direction of the shell 10, the second direction Y and the third direction Z intersect, the second direction Y is the width direction of the shell 10, and the third direction Z is the height direction of the shell 10. Optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0042] Generally, each project has different requirements and specific battery sampling channels and quantities. Therefore, a set of sampling harness can only be used in the project and cannot be applied to other sampling harnesses. This means that when using the same BMS mainboard to collect different AFE electrode assemblies, an independent sampling environment needs to be built for each project to meet their respective needs. In this case, for each project, the corresponding sampling harness needs to be customized according to the specific battery sampling channels and quantities, which not only requires more equipment, but also makes it more troublesome to arrange the harness during construction.

[0043] AFE sampling means that there are multiple sampling lines for one AFE, which can be 14, 16, 18, etc. The reference voltage of the AFE sampling line uses the voltage of the previous sampling line. For example, the reference voltage of the 1st electrode assembly sampling is the negative electrode of the 1st electrode assembly, the reference voltage of the 2nd electrode assembly sampling is the positive electrode of the 1st electrode assembly, and the reference voltage of the 3rd electrode assembly sampling is the positive electrode of the 2nd electrode assembly. However, not all AFE sampling lines are used, such as the 4th electrode assembly sampling line connected to the copper bar or not used, which is connected to the 3rd electrode assembly sampling line (the positive electrode of the 3rd electrode assembly). Because the reference voltage of the 5th electrode assembly sampling line is the 3rd electrode assembly sampling line (the positive electrode of the 3rd electrode assembly).

[0044] Suppose that the BMS electrode assemblies of three different types of vehicles need to be sampled, and the mainboards of the vehicles are all the same, but the configurations of the AFE sampling lines and the number of samples are different. For example, the first type of vehicle needs to collect 14 channels of the first AFE, so the battery simulation system has No. 1 electrode assembly, No. 2 electrode assembly, No. 3 electrode assembly, …, No. 14 electrode assembly, and the AFE sampling line has the sampling line of No. 1 electrode assembly, the sampling line of No. 2 electrode assembly, the sampling line of No. 3 electrode assembly, …, the sampling line of No. 14 electrode assembly. Among them, the sampling line of No. 3 electrode assembly, the sampling line of No. 4 electrode assembly, and the sampling line of No. 5 electrode assembly need to be connected in parallel to No. 3 electrode assembly of the battery simulation system, the sampling line of No. 6 electrode assembly is connected to No. 4 electrode assembly of the battery simulation system, and so on, and the sampling line of No. 14 electrode assembly is connected to No. 12 electrode assembly of the battery simulation system. The second type of vehicle needs to collect 14 channels of the first AFE, so the battery simulation system has No. 1 electrode assembly, No. 2 electrode assembly, No. 3 electrode assembly, …, No. 14 electrode assembly, and the AFE sampling line has the sampling line of No. 1 electrode assembly, the sampling line of No. 2 electrode assembly, the sampling line of No. 3 electrode assembly, …, the sampling line of No. 14 electrode assembly. Among them, the sampling line of No. 5 electrode assembly and the sampling line of No. 6 electrode assembly need to be connected in parallel to No. 5 electrode assembly of the battery simulation system, the sampling line of No. 7 electrode assembly is connected to No. 6 electrode assembly of the battery simulation system, and so on, and the sampling line of No. 14 electrode assembly is connected to No. 13 electrode assembly of the battery simulation system. The third type of vehicle needs to collect 14 channels of the first AFE, so the battery simulation system has No. 1 electrode assembly, No. 2 electrode assembly, No. 3 electrode assembly, …, No. 14 electrode assembly, and the AFE sampling line has the sampling line of No. 1 electrode assembly, the sampling line of No. 2 electrode assembly, the sampling line of No. 3 electrode assembly, …, the sampling line of No. 14 electrode assembly. The sampling line of the electrode assembly corresponds to the electrode assembly one by one, and there is no sampling line to be connected together; similarly, the sampling configurations of other AFEs are also different (generally, a BMS has 6 to 9 AFEs), at this time, 3 different sampling harnesses are needed to meet the development needs of the project. In order to save the development cycle and facilitate the maintenance of the environment and facilitate the problem checking, it is urgently needed to have a set of sampling harnesses that can meet different sampling needs.

[0045] Therefore, the embodiment of the present application provides a sampling harness connection device, which can quickly adjust the connection between the sampling line in the sampling harness and the corresponding electrode assembly, so that a set of sampling harnesses can meet different sampling needs, thereby solving at least part of the above technical problems.

[0046] Please refer to Figure 1 , Figure 1The schematic diagram of the overall structure of a sampling harness connection device provided in an embodiment of the present application includes a shell 10, a plurality of sampling harness guide rails 20, a plurality of first conductors 30, and a slider 40. The shell 10 has a accommodating cavity 12, and the shell 10 has a first direction X, a second direction Y, and a third direction Z that intersect with each other. It should be noted that the shell 10 can be a box structure with an open surface formed by four side panels enclosed on a bottom plate, and the interior of the box structure is the accommodating cavity 12. A plurality of sampling harness guide rails 20 are connected to the shell 10 and arranged along the second direction Y. It should be noted that a plurality of sampling harness guide rails 20 are arranged on the open surface of the box structure, so as to ensure that the positive projection of each sampling harness guide rail 20 covers each first conductor 30; there is a gap between adjacent sampling harness guide rails 20. The plurality of first conductors 30 are located within the accommodating cavity 12, so that the housing 10 can protect the plurality of first conductors 30 and prevent the plurality of first conductors 30 from being affected by external factors such as impact, vibration, and temperature change. The plurality of first conductors 30 are connected to the housing 10 and arranged in parallel along the first direction X, so that the housing 10 has a certain guiding effect on the arrangement of the plurality of first conductors 30. The first conductors 30 and the sampling harness guide rail 20 are spaced apart in the third direction Z, that is, the first conductors 30 and the sampling harness guide rail 20 are not in direct contact. The slider 40 is connected to the sampling harness guide rail 20 and is located between the first conductors 30 and the sampling harness guide rail 20. The slider 40 can move relative to the sampling harness guide rail 20 along the first direction X, and the sampling harness guide rail 20 is connected to any one of the plurality of first conductors 30 through the slider 40.

[0047] In light of this, this embodiment makes the connection of the sampling line more flexible and adjustable, capable of adapting to the battery sampling channel and quantity requirements of different projects. By moving the slider 40 along the first direction X relative to the sampling harness guide 20, the sampling line can be quickly switched to connect to different first conductors 30, thereby meeting the sampling requirements of different environments. This flexibility and adjustability eliminates the need to set up multiple sampling environments when sampling different AFE cells using the same BMS motherboard, eliminating the need to organize the wiring harness.

[0048] In some embodiments, see Figure 2 , Figure 2This is an exploded schematic diagram of the overall structure of a sampling harness connection device provided in an embodiment of the present application. A plurality of harness holes 11 are provided on the shell 10 along the first direction X, and each harness hole 11 corresponds to a first conductor 30. It should be noted that each first conductor 30 is connected to an electrode assembly at one end close to the harness hole 11. Assuming that voltage sampling is required for 14 electrode assemblies, there are 14 harness holes 11, and the electrode assembly is connected to the first conductor 30 by passing a wire through the corresponding harness hole 11, that is, each first conductor 30 corresponds to an electrode assembly. The sampling line in the sampling harness is connected to the corresponding first conductor 30 to sample the voltage of the corresponding electrode assembly.

[0049] In view of this, the harness hole 11 of this embodiment facilitates the connection between the first conductor 30 and the electrode assembly. By passing the wire through the harness hole 11, the electrode assembly can be connected to the corresponding first conductor 30 to achieve the purpose of voltage sampling. This embodiment makes the connection of the sampling line more flexible and adjustable, and can adapt to the battery sampling channel and quantity requirements of different projects. By moving the slider 40 along the first direction X relative to the sampling harness guide 20, the sampling line can be quickly switched to connect with different first conductors 30, thereby meeting the sampling needs in different environments. This flexibility and adjustability makes it no longer necessary to build multiple sets of sampling environments separately when using the same BMS motherboard to collect different AFE batteries, avoiding the need to organize the harness.

[0050] In some embodiments, see Figure 3 , Figure 3 A schematic diagram of the overall structure of a slider provided in an embodiment of the present application. Slider 40 includes a mounting hole 41, which is provided through sampling harness rail 20. Slider 40 is mounted on sampling harness rail 20 through mounting hole 41, connecting slider 40 to sampling harness rail 20 while enabling slider 40 to slide on sampling harness rail 20.

[0051] In view of this, in this embodiment, a physical connection is established between the slider 40 and the sampling harness guide rail 20 through the mounting hole 41. The design of the mounting hole 41 enables the slider 40 to slide along the sampling harness guide rail 20 in the first direction X. This design provides flexibility and adjustability, allowing the slider 40 to move freely on the sampling harness guide rail 20 to adapt to different sampling requirements. By sliding the slider 40 on the sampling harness guide rail 20, the connection between the sampling line and different electrode assemblies can be quickly adjusted. The position of the slider 40 determines which electrode assembly the sampling harness is connected to, thereby enabling sampling of different electrode assemblies. This adjustability allows a set of sampling harnesses to adapt to different sampling configurations without having to replace the harness or rewire. Therefore, through the connection between the mounting hole 41 of the slider 40 and the sampling harness guide rail 20, the slider 40 can slide on the sampling harness guide rail 20, thereby achieving flexible adjustment of the sampling harness and the ability to adapt to different sampling requirements. This design simplifies the adjustment process of the sampling harness and improves sampling efficiency.

[0052] In some embodiments, the sampling wire harness connection device further includes a pogo pin probe 50, which is disposed on the side of the slider 40 facing the first conductor 30, is connected to the slider 40, and contacts the first conductor 30. The slider 40 is connected to the first conductor 30 via the pogo pin probe 50, and the pogo pin probe 50 also enables electrical connection between the sampling wire and the electrode assembly.

[0053] In view of this, the spring needle probe 50 of this embodiment can provide a stable electrical connection through its elastic design. When the slider 40 contacts the first conductor 30, the spring needle probe 50 will be compressed, so that its needle tip is in close contact with the first conductor 30, ensuring the transmission quality of the electrical signal. Through the connection of the spring needle probe 50, the slider 40 can achieve a reliable electrical connection with the first conductor 30. In this way, the sampling line in the sampling harness can establish an electrical connection with the corresponding electrode assembly through the slider 40, the spring needle probe 50 and the first conductor 30, achieving the purpose of voltage sampling. The function of the spring needle probe 50 is to ensure stable electrical connection and signal transmission quality. It can adapt to the movement and vibration of the slider 40 and can be in close contact with the first conductor 30, thereby ensuring a stable and reliable electrical connection between the sampling line and the electrode assembly. The design of the spring needle probe 50 enables the sampling harness connection device to provide accurate voltage sampling under different sampling conditions, ensuring the accuracy and reliability of the data.

[0054] In some embodiments, see Figure 4 , Figure 4This is a schematic diagram of the overall structure of the first conductor provided in an embodiment of the present application. The first conductor 30 has multiple connection slots 31 defined along a first direction X, and the pogo pin probes 50 are positioned within the connection slots 31. It is noteworthy that the number of connection slots 31 matches the number of sliders 40, that is, the number provided on the sampling harness rail 20. When the slider 40 moves until the pogo pin probes 50 contact the connection slots 31, the slider 40 establishes a connection with the first conductor 30.

[0055] In light of this, this embodiment provides multiple connection slots 31 on the first conductor 30 to establish corresponding connection points with the slider 40. The connection slots 31 connect to the pogo pin probes 50, ensuring a stable electrical connection. When the slider 40 moves to contact a connection slot 31, the pogo pin probe 50 inserts into that slot, establishing an electrical connection between the slider 40 and the first conductor 30. This design enables the slider 40 to move along the sampling harness rail 20 in the first direction X and connect to different connection slots 31 of the first conductor 30. The movement of the slider 40 allows for rapid switching of the connection between the sampling line and different electrode assemblies to meet diverse sampling requirements. When the pogo pin probes 50 on the slider 40 contact a connection slot 31, electrical connection is established between the slider 40 and the first conductor 30, enabling voltage sampling of the corresponding electrode assembly. Therefore, the design of the connection slots 31 and pogo pin probes 50 on the first conductor 30 achieves a reliable electrical connection between the slider 40 and the first conductor 30. This design makes the sampling harness connector flexible and adjustable to accommodate different sampling configurations and requirements. It also simplifies the sampling harness adjustment process, improves sampling efficiency, and enhances system scalability.

[0056] In some embodiments, the pogo pin probe 50 includes a body 51, which is disposed on the side of the slider 40 facing the first conductor 30 and is connected to the slider 40. The pogo pin probe 50 also has a first curved surface 52, which is located on the side of the body 51 facing away from the slider 40. The provision of the first curved surface 52 facilitates smoother movement of the slider 40 as it passes over the edge of the first conductor 30. The first curved surface 52 can be hemispherical or parabolic in shape to achieve this smooth movement. In fact, as long as the shape of the first curved surface 52 enables smoother movement of the slider 40 as it passes over the edge of the first conductor 30, any curved shape can be used, not limited to hemispherical or parabolic shapes.

[0057] In view of this, the spring needle probe 50 of this embodiment having a first curved surface 52 has the following advantages. First, the first curved surface 52 can reduce the friction between the slider 40 and the first conductor 30, making the slider 40 smoother during movement. Second, the first curved surface 52 can provide a larger contact area, increasing the contact surface between the slider 40 and the first conductor 30, thereby improving the stability and reliability of the electrical connection. In addition, the first curved surface 52 can also reduce wear between the slider 40 and the first conductor 30, extending the service life of the sampling harness connection device. The first curved surface 52 of the spring needle probe 50 allows the slider 40 to pass the edge of the first conductor 30 more smoothly during movement. This design reduces friction and wear, improving the performance and reliability of the sampling harness connection device. Therefore, the first curved surface 52 of the spring needle probe 50 provides better smoothness and reliability for the movement of the slider 40 in the sampling harness connection device.

[0058] In some embodiments, see Figure 3 and Figure 5 , Figure 3 This is a schematic diagram of the overall structure of the slider provided in the embodiment of the present application. Figure 5 Schematic diagram of the cross-sectional structure of the first conductor provided in an embodiment of the present application. The side of the first conductor 30 facing the spring needle probe 50 is a first surface 32; the connecting groove 31 has an opening 311 and a second curved surface 312 opposite to the opening 311, the opening 311 passes through the first surface 32, and the second curved surface 312 is adapted to the first curved surface 52. Specifically, when the first curved surface 52 is hemispherical, the second curved surface 312 is also hemispherical; when the first curved surface 52 is parabolic, the second curved surface 312 is also parabolic. Such a design allows the second curved surface 312 to contact the first curved surface 52 smoothly, and allows the spring needle probe 50 to easily detach from the connecting groove 31.

[0059] In view of this, this embodiment achieves the following advantages by designing the second curved surface 312 of the connecting slot 31 as an arc-shaped groove that matches the first curved surface 52 of the pogo pin probe 50. First, the shape of the arc-shaped groove allows the pogo pin probe 50 to be smoothly inserted into the connecting slot 31, ensuring a stable electrical connection. Second, the arc-shaped groove design allows the pogo pin probe 50 to easily disengage from the connecting slot 31, thereby achieving rapid connection and disconnection between the slider 40 and the first conductor 30. This design of the arc-shaped groove that matches the first curved surface 52 of the pogo pin probe 50 allows the slider 40 to smoothly pass over the edge of the first conductor 30 during movement. When the slider 40 moves into contact with the connecting slot 31, the pogo pin probe 50 can be smoothly inserted into the connecting slot 31, ensuring the quality of electrical signal transmission. When the slider 40 moves away from the connecting slot 31, the pogo pin probe 50 can easily disengage from the connecting slot 31, achieving a disconnection of the electrical connection. Therefore, by adapting the second curved surface 312 of the connection groove 31 to the first curved surface 52 of the pogo pin probe 50, a stable electrical connection is achieved between the slider 40 and the first conductor 30, and the slider 40 can smoothly pass the edge of the first conductor 30 during movement. This design improves the reliability and operability of the sampling harness connection device, making the voltage sampling process smoother and more efficient.

[0060] In some embodiments, in order to prevent short circuits between adjacent first conductors 30, the sampling harness connection device further includes a plurality of insulating partitions 60. These insulating partitions 60 are disposed between two adjacent first conductors 30 to provide isolation and insulation.

[0061] In view of this, the presence of the insulating spacers 60 in this embodiment offers the following advantages. First, they effectively prevent short circuits between adjacent first conductors 30, ensuring the proper operation of the sampling harness connection device. By placing the insulating spacers 60 between the first conductors 30, they effectively isolate adjacent first conductors 30, preventing accidental short circuits between them. Second, the insulating spacers 60 provide additional insulation protection, reducing the possibility of current leakage and interference. They form an insulating barrier between adjacent first conductors 30, preventing current transconductance, thereby improving the stability and reliability of voltage sampling. Furthermore, the insulating spacers 60 provide mechanical support and fixation, ensuring the stable layout and position of the first conductors 30. They can be fixed to the sampling harness rail 20, maintaining the spacing and relative position of the first conductors 30, thereby ensuring accurate alignment of the connection slots 31 with the pogo pin probes 50. By introducing the insulating spacers 60, the sampling harness connection device effectively prevents short circuits between adjacent first conductors 30 and provides additional insulation protection and mechanical support. This design enhances the safety and stability of the sampling harness connection device and ensures the reliable operation of the sampling harness connection device.

[0062] In some embodiments, the design of the sampling harness connection device can meet the connection requirements with 14 battery cells (Cell 1 to Cell 14 ) in the battery simulation system. Figure 1 A specific example is shown in which a single AFE (analog front end) with 14 sampling channels is used. Each sampling channel needs to be connected to the corresponding battery cell. To achieve this connection, each sampling line in the sampling harness is connected to a sampling harness rail 20. Each sampling harness rail 20 has a unique connection to a battery cell (Cell1 to Cell14) in the battery simulation system. The number of sliders 40 matches the number of battery cells, that is, there are 14 sliders 40, corresponding to the first slider, the second slider, the third slider, and so on, until the fourteenth slider. By pushing the 14 sliders 40, the connection status of the sampling harness rail 20 connected to the sampling line and the battery cell can be changed. For example, if the project requirement does not use sampling line No. 5 of the AFE, but the reference voltage of sampling line No. 6 is sampling line No. 5, then both sampling line No. 4 and sampling line No. 5 need to be connected to Cell4. To achieve this connection, just push the fourth and fifth sliders to the connection slot 31 of the first conductor 30 connected to Cell4, then push the sixth slider to the connection slot 31 of the first conductor 30 connected to Cell5, and so on. By pushing the sliders 40 one by one, the connection with each battery cell can be achieved. This design enables the sampling harness connection device to flexibly adjust the connection status of the sampling channel according to actual needs. By pushing the slider 40, the connection between the sampling harness guide 20 and the battery cell can be quickly changed to achieve the connection of the sampling line → sampling harness guide → slider → battery cell conductor → battery simulation system to meet different sampling needs. This flexibility and adjustability makes the sampling harness connection device suitable for battery simulation systems of different specifications and configurations.

[0063] In some embodiments, in order to ensure the stable connection and insulation isolation between the first conductor 30 and the shell 10, an insulating glue can be used for fixation. The insulating glue is an adhesive with insulating properties, which can form an insulating barrier between the first conductor 30 and the shell 10. By using the insulating glue for fixation, the following advantages can be achieved. First, the insulating glue can provide additional insulation protection to prevent current leakage and interference between the first conductor 30 and the shell 10. It forms an insulating layer between the first conductor 30 and the shell 10, effectively isolating the first conductor 30 and the shell 10, preventing current transduction and short circuit.
