DETAILED DESCRIPTION

[0041] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar components. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0042] In recent years, energy storage technology has been widely used in new energy vehicles, power systems, and industrial manufacturing fields. In order to monitor the working state of each battery cell in the energy storage device, the CCS collects and outputs the data such as the electrical signal and temperature of the battery cell. The structure design and integration level of the CCS affect the accuracy of data acquisition and the stability of data transmission.

[0043] In the CCS, the output row is one of the key components, responsible for transmitting the collected battery data signal to the external system or controller, however, the output row itself does not have insulation protection function. Therefore, in practical application, in order to ensure the safety and stability of data transmission, additional insulation protection measures are needed outside the output row to prevent short circuit and leakage caused by direct contact between the output row and the metal end plate.

[0044] The prior art is usually to take the output pole block as an independent part connected with the output row to avoid contact between the output row and the metal end plate, and to realize the insulation treatment of the output row. For example, the output pole block is first installed on the metal end plate, then the CCS is buckled on the pole of the battery cell, and then the output aluminum row in the CCS is connected with the output pole block by screws, and finally the welding work between the CCS and the battery cell is carried out. This method is complex in process, high in cost and low in efficiency. In addition, the output pole block can be combined with the mounting bracket of the CCS by integral injection molding. In this scheme, the volume of the injection mold is large, the cost is high, and the mounting bracket obtained from the above injection mold is heavy and large in volume, so that the final integrated battery module is large in weight and volume, which is not convenient to use.

[0045] Therefore, the prior art has the problems of high cost, multiple processes and low production efficiency, and the battery module obtained by combining the output pole block and the mounting bracket by integral injection molding has the problems of large weight and volume, which is not convenient to use.

[0046] In order to solve the above technical problems, the battery module integrated busbar provided by the embodiments of the present application includes a bracket, a plurality of series rows, two output rows and two output pole blocks, wherein the bracket includes a positive end and a negative end, the two output rows are respectively arranged at the positive end and the negative end of the bracket, and for any one output row, the output row is mounted in the corresponding first mounting groove, the first part of the output row extends to the outside of the bracket along the opening of the first mounting groove, the bottom of the first part is provided with a corresponding output pole block, which serves as an insulation partition plate to isolate and insulate the first part of the output row from the metal end plate outside the battery module, avoiding direct contact between the output row and the metal end plate, which may cause short circuit or leakage and other safety hazards. In addition, the output pole block is integrated at the bottom of the first part of the output row, which simplifies the production process of the module, improves the production efficiency, does not need additional injection molding bracket, reduces the production cost, and also does not have the problem of large weight and volume of the battery module caused by the large mounting bracket, which is not convenient to use.

[0047] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0048] Figure 1 A structure diagram of a battery module integrated busbar provided for an embodiment of the present application Figure 1 , Figure 2 A structure diagram of a battery module integrated busbar provided for an embodiment of the present application Figure 2 .

[0049] With reference to Figure 1 , the present application provides a battery module integrated busbar, which comprises a support 110, a plurality of series connection buses, a first output bus 130 and a second output bus 131, a first output pole block 140 and a second output pole block 141.

[0050] Among them, one of the plurality of series connection buses is, for example, the first series connection bus 120 in Figure 1 , the first region 111 and the second region 112 of the support 110 are each provided with a preset number of series connection buses, as shown in Figure 1 , each series connection bus is installed in a corresponding installation slot, for example, the first series connection bus 120 is installed in a corresponding third installation slot 113.

[0051] Optionally, a buckle assembly and a spring assembly can be arranged in the installation slot corresponding to the series connection bus, wherein the buckle assembly is used to limit the busbar, and the spring assembly further fixes the series connection bus through elastic deformation. For example, the buckle assembly limits the series connection bus between the buckle and the spring, and the spring in the spring assembly has a protruding portion, the protruding direction of the protruding portion being opposite to the elastic deformation direction of the spring. When the buckle assembly limits the series connection bus, the protruding portion abuts against the surface of the series connection bus facing the installation slot, forming an interference fit.

[0052] It can be understood that the hot riveting process can also be used to fix the plurality of series connection buses in the corresponding plurality of installation slots in the support 110. It should be noted that the fixing process of the series connection bus can be adjusted according to actual use requirements, which is not limited in the present application.

[0053] Specifically, the plurality of series connection buses are connected in series in order to form an output loop, and the two ends of the output loop are connected to the two output buses, as shown in Figure 1As shown, the bracket 110 of the battery module integrated busbar includes a positive end and a negative end, the first output row 130 of the two output rows is installed at the negative end of the bracket 110 and is connected with the negative end of the first series row 120, the negative end is connected with the negative pole of the corresponding battery cell, and the second output row 131 is installed at the positive end of the bracket 110 and is connected with the positive end of the second series row 121. Among them, the series rows can be connected by direct welding, or can be connected by a crimp connector or a terminal, in addition, a flexible connecting wire or a connector can also be used to connect the series rows, and the application does not limit this. It can be understood that the connection mode between the series rows and the output rows is similar to the connection mode between the series rows and the series rows, and the application does not limit the connection mode between the series rows and the output rows.

Therefore, when the battery module integrated busbar and the plurality of battery cells are assembled into a battery module, the first part of the first output row 130 will contact the metal end plate of the assembled shell. Since the first output row 130 itself does not have an insulation function, a corresponding output pole block 140 is arranged at the bottom of the first part of the first output row 130, which is used to isolate the first part of the first output row 130 from the metal end plate of the assembled shell, so as to insulate the first output row 130.

[0055] It can be understood that the installation structure of the second output row 131 is similar to that of the first output row 130, which will not be described here.

[0056] Optionally, the bracket 110 can be obtained by injection molding process, or by suction molding and blow molding process, and the application does not limit this.
