[0003] The above prior art solutions have the following defects: The existing busbar has the problems of complex structure and high cost. Utility Model Content

[0004] In order to simplify the busbar structure and save costs, this application provides a CCS integrated busbar.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] A CCS integrated busbar includes a bracket. The bracket is connected with a conductive carrier. The conductive carrier includes two end carriers and multiple intermediate carriers. The two end carriers are respectively arranged at both ends of the bracket. The multiple intermediate carriers are staggered and arranged on opposite sides of the bracket. An integrated wire harness is arranged on the bracket. The integrated wire harness is connected with the conductive carrier. The integrated wire harness includes a voltage detection wire harness and a temperature acquisition wire harness. The voltage detection wire harness is connected with the two end carriers and the multiple intermediate carriers. The temperature acquisition wire harness is connected with the end carriers and the intermediate carriers. Temperature collectors are arranged at the joints of the temperature acquisition wire harness with the end carriers and the intermediate carriers.

[0007] By adopting the above solution, the positive and negative electrodes of the battery cells are respectively connected to the end carrier and the adjacent intermediate carrier. Subsequently, the positive and negative electrodes of the second battery cell are connected to two adjacent intermediate carriers, and the battery cells are arranged horizontally on the bracket. This process is repeated until the positive or negative electrode of the last battery cell is connected to the other end carrier, thereby realizing the series connection of multiple battery cells, and thus monitoring the working state of the battery cells in real time. The voltage detection wire harness can detect the voltage between each battery cell and transmit the voltage condition to the battery management system, thereby detecting whether the working state of the battery cells is normal. The temperature acquisition wire harness can detect the temperature between each battery cell and transmit the temperature condition to the battery management system, thereby detecting whether the working state of the battery cells is normal. The structure of this busbar is relatively simple and the production cost is relatively low.

[0008] Optionally, a plurality of explosion-proof valve avoidance holes are opened in the middle of the bracket, and the plurality of explosion-proof valve avoidance holes are evenly arranged along the direction of the bracket.

[0009] By adopting the above solution, the explosion-proof valve avoidance hole corresponds to the explosion-proof valve position of the battery, ensuring that the use of the explosion-proof valve is unobstructed and the safety of the battery pack is ensured.

[0010] Optionally, a central partition plate is provided above the bracket, and two central partition plates are provided. The two central partition plates are respectively located at opposite ends of the socket, and one end of the integrated wiring harness connected to the conductive carrier is located outside the central partition plate, and the end of the integrated wiring harness connected away from the conductive carrier is located between the two central partition plates.

[0011] By adopting the above solution, the wiring harnesses on both sides above the bracket are separated, and the integrated wiring harness can be bent above the bracket, thereby reducing the space occupied by the busbar. At the same time, the central partition plate also protects the integrated wiring harness.

[0012] Optionally, the end of the integrated wiring harness away from the end connected to the conductive carrier is wrapped together with an insulating tape.

[0013] By adopting the above solution, the integrated wiring harnesses are bundled together, thereby further reducing the space occupied by the integrated wiring harnesses, while facilitating the arrangement and inspection of the integrated wiring harnesses. In addition, the integrated wiring harnesses bundled together are less likely to break.

[0014] Optionally, edge separators are provided on opposite sides of the upper surface of the bracket, and a plurality of notches are provided on the surface of the edge separators, and the integrated wiring harness passes through the notches and is connected to the conductive carrier.

[0015] By adopting the above solution, the edge partition plate and the center partition plate sandwich the ends of the integrated wiring harness for protection, and the integrated wiring harness passes through the notch to be connected to the wire carrier. In addition, the notch can also position the wire core, making it more convenient to place the wire core.

[0016] Optionally, ear plates are fixedly provided on the sides of the two edge partition plates facing away from each other, and circular holes are opened on the surfaces of the ear plates.

[0017] By adopting the above solution, the installation of the busbar and the battery is more convenient, and the busbar can be installed by passing screws through the round holes.

[0018] Optionally, a plurality of center card blocks are arranged above the side of the center partition plate close to the edge partition plate, and a plurality of edge card blocks are arranged above the side of the edge partition plate close to the center partition plate. There is a certain distance between the edge card blocks and the center card blocks, and the edge card blocks and the center card blocks are arranged alternately.

[0019] By adopting the above scheme, when installing the integrated wiring harness, the integrated wiring harness is passed between the center card block and the edge card block, so that the integrated wiring harness enters between the edge partition plate and the center partition plate. The edge card block on one side of the center card block has a limiting and protective effect on the integrated wiring harness, thereby restricting the integrated wiring harness between the center partition plate and the edge partition plate. In addition, using this method to limit the wiring harness makes molding more convenient and requires less consumables.

[0020] Optionally, a protrusion is provided on the middle carrier, and a protrusion is provided on the end carrier.

[0021] By adopting the above solution, the protrusion can separate two adjacent battery cells, and the protrusion can increase current-carrying protection by increasing the cross-sectional area.

[0022] Optionally, a plurality of plug rods are provided at the edge of the bracket, and plug holes are provided on the middle carrier and the end carrier, and the plug rods are inserted into the plug holes.

[0023] By adopting the above solution, the bracket and the conductive carrier are connected by inserting the insertion rod into the insertion hole, so that the operator can more quickly position and limit the conductive carrier, which facilitates the subsequent further fixation of the conductive carrier and the bracket.

[0024] Optionally, a through hole is formed at one end of the bracket, and a fixing rod is provided at one end of the bracket away from the through hole.

[0025] By adopting the above technical solution, the operator can fix the two brackets together by inserting the fixing rod of one of the brackets into the through hole, so that the busbar can adapt to battery packs of more sizes.

Detailed implementation manners

[0035] The following further elaborates on the present application in conjunction with the accompanying drawings.

[0036] Referring to Figure 1 and Figure 2 , a CCS integrated busbar includes a bracket 1. A conductive carrier 2 is connected to the bracket 1. The conductive carrier 2 includes two end carriers 21 and a plurality of intermediate carriers 22. The two end carriers 21 are respectively arranged at both ends of the bracket 1. The plurality of intermediate carriers 22 are staggered and arranged on opposite sides of the bracket 1. An integrated wire harness 3 is arranged on the bracket 1. The integrated wire harness 3 is connected to the conductive carrier 2, and the other end of the integrated wire harness 3 is connected to the battery management system. When the busbar is in use, the positive and negative electrodes of the battery cells are respectively connected to the end carrier 21 and the adjacent intermediate carrier 22. Subsequently, the positive and negative electrodes of the second battery cell are connected to two adjacent intermediate carriers 22, and the battery cells are horizontally arranged on the bracket 1. This process is repeated until the positive or negative electrode of the last battery cell is connected to the other end carrier, thereby realizing the series connection of multiple battery cells. Moreover, the integrated wire harness 3 can detect the signals between every two adjacent battery cells and transmit them to the battery management system, so as to monitor the working state of the battery cells in real time. The bracket 1 is made of plastic by integral molding, which can not only meet the insulation of the bracket 1, but also has cheap materials, simple molding and low production cost.

[0037] Referring to Figure 1 and Figure 2, the integrated wire harness 3 includes a voltage detection wire harness 31 and a temperature acquisition wire harness 32. The voltage detection wire harness 31 is connected to the two end carriers 21 and all the intermediate carriers 22, enabling the battery management system to detect the voltage conditions between each cell in real time, thereby determining whether the cells are operating normally. The temperature acquisition wire harness 32 can be connected to the end carrier 21 and the intermediate carrier 22 according to requirements. A temperature collector is provided at the connection between the temperature acquisition wire harness 32 and the end carrier 21 and the intermediate carrier 22. For example, the temperature acquisition wire harness 32 can be connected every three carriers. The temperature acquisition wire harness 32 collects the temperature between the cells and sends the temperature signal to the battery management system, enabling the battery management system to detect the temperature between each wire in real time and avoid danger caused by excessive cell temperature.

[0038] Referring to Figure 1 and Figure 2 , a plurality of insertion rods 11 are provided at the edge of the bracket 1, and insertion holes 7 are formed in both the end carrier 21 and the intermediate carrier 22. When installing the intermediate carrier 22 and the end carrier 21, the insertion rods 11 can be inserted into the insertion holes 7 to position and fix the end carrier 21 and the intermediate carrier 22. Subsequently, the end carrier 21 and the intermediate carrier 22 are reinforced, making the installation of the end carrier 21 and the intermediate carrier 22 more convenient and accurate. Protrusions 6 are provided on the surfaces of the intermediate carrier 22 and the end carrier 21. The protrusions 6 can separate two adjacent cells, and at the same time, the protrusions 6 can increase the current-carrying protection by increasing the cross-sectional area.

[0039] Referring to Figure 1 and Figure 3, on the upper surface of the bracket 1, a plurality of explosion-proof valve avoidance holes 12 are provided. The explosion-proof valve avoidance holes 12 are evenly arranged along the direction of the bracket 1. The explosion-proof valve avoidance holes 12 correspond to the positions of the explosion-proof valves of the battery, ensuring that there are no obstacles to the use of the explosion-proof valves and guaranteeing the safety of the battery pack. And a central partition plate 4 is fixedly arranged on the upper surface of the bracket 1. There are two central partition plates 4, and the two central partition plates 4 are respectively located on both sides of the explosion-proof valve avoidance holes 12. Edge partition plates 5 are arranged on the mutually facing sides of the central partition plates 4. The edge partition plates 5 are arranged at the edges of the bracket 1, and a plurality of notches are provided on the surfaces of the edge partition plates 5. The integrated wire harness 3 passes through the notches and is connected to the conductive carrier 2. In addition, the notches can also position the wire cores, making it more convenient to place the wire cores. One end of the integrated wire harness 3 connected to the conductive carrier 2 is placed between the central partition plate 4 and the edge partition plate 5, and one end of the integrated wire harness 3 connected to the battery management system is folded between the two central partition plates 4, and this end of the integrated wire harness is wound together with insulating tape, bundling the integrated wire harness 3 together, thereby further reducing the space occupied by the integrated wire harness 3, while facilitating the arrangement and inspection of the integrated wire harness 3. In addition, the integrated wire harness 3 bundled together is less likely to break. Thus, the edge partition plate 5 and the central partition plate 4 protect and limit the integrated wire harness 3, and the folded placement of the integrated wire harness 3 makes the space of the busbar smaller.

[0040] Refer to Figure 2 and Figure 3 , on the side of the edge partition plate 5 close to the central partition plate 4, an edge clamping block 51 is fixedly arranged. On the side of the central partition clamping plate close to the edge partition plate 5, a central clamping block 41 is fixedly arranged. There are a plurality of central clamping blocks 41 and edge clamping blocks 51. The plurality of central clamping blocks 41 and edge clamping blocks 51 are arranged in an alternating manner, and there is a certain gap between the central clamping blocks 41 and the edge clamping blocks 51. The central clamping blocks 41 and the edge clamping blocks 51 are respectively located at the upper positions of the central partition plate 4 and the edge partition plate 5. When placing the integrated wire harness 3 between the central partition plate 4 and the edge partition plate 5, the integrated wire harness 3 is passed through between the central clamping blocks 41 and the edge clamping blocks 51. The central clamping blocks 41 and the edge clamping blocks 51 play a role in limiting and protecting the integrated wire harness 3, making it difficult for the integrated wire harness 3 to come out between the central clamping blocks 41 and the edge clamping blocks 51. In addition, using this method to limit the wire harness is more convenient for forming and consumes less material. And a plurality of ear plates 52 are arranged on the mutually facing sides of the two edge clamping blocks 51. Round holes are provided on the ear plates 52, making it more convenient to install the busbar and the battery. The busbar can be installed by passing screws through the round holes.

[0041] Refer to Figure 4, a through hole 13 is provided at one end of the bracket 1, and a fixing rod 14 is provided at the other end of the bracket 1 where the through hole 13 is provided. An operator can insert the fixing rod 13 of one bracket 1 into the through hole 13, thereby fixing the two brackets 1 together, thereby connecting the two busbars together, thereby improving the applicability of the busbars.

[0042] This specific embodiment is only an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
