Description

Technical Field

[0001] The utility model relates to a CCS isolation plate, in particular to a novel CCS component. Background Art

[0002] CCS (battery connection system) technology for power batteries plays a vital role in the new energy vehicle and electrochemical energy storage industries. These industries are experiencing rapid growth, and the demand for CCS has surged accordingly.

[0003] The CCS, also known as the cable board assembly, consists of signal acquisition components (such as wiring harnesses, FPCs, FFCs), plastic structural components, and copper and aluminum busbars connected together through processes such as heat pressing or riveting. This system enables high-voltage series and parallel connection of battery cells, as well as temperature and cell voltage sampling. As part of a battery management system (BMS), it is primarily used in new energy power batteries and energy storage batteries, improving the overall efficiency and safety of battery systems.

[0004] CCS technology is developing towards higher integration, reliability, and cost-effectiveness. In traditional CCS assembly solutions, flexible printed circuits (FPCs) are used for electrical connections and signal acquisition, while isolation boards provide physical isolation and support. However, this solution offers suboptimal integration and a less compact structural design, resulting in inefficient space utilization and high material costs. In this traditional solution, securing the FPC to the aluminum bar has always been a challenge, increasing process complexity and further increasing manufacturing costs. Utility Model Content

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] like Figure 1-4 As shown together, this embodiment is about a new CCS component, including a PCB board 1 as a supporting structure, on which a connector 2, an output pole 3, a connecting bus 4 and an NTC component 5 are provided. The connector 2, the output pole 3 and the connecting bus 4 are all located on the front of the PCB board 1. The connecting bus 4 is fastened to the connecting bus 4 by bolts 7 and electrically double-connected. The connecting bus 4 is also assisted in positioning and connecting with the connecting bus 4 by a positioning lock buckle 9. It should be noted that the connector 2 is used for electrical connection, the output pole 3 is used for outputting current, the connecting bus 4 is used for current conduction, and the NTC component 5 is used for temperature collection.

[0023] In this embodiment, the PCB board 1 adopts FR-4 material, which is an existing material. Figure 1 The structural design shown provides good mechanical support and circuit integration functions, allowing this embodiment to replace the FPC and isolation board in the traditional CCS assembly with the PCB board 1. Based on the integration of the functions and effects of the FPC and isolation board, the cost is significantly reduced, the performance is significantly improved, and more space configuration possibilities are available. In actual use, the PCB board 1 also integrates the functions of voltage sampling and temperature sampling, further simplifying the system design.

[0024] The connector 2 is located on the short side of the PCB board 1 .

[0025] There are two output poles 3 , which are respectively located on two long sides of the PCB board 1 and are arranged diagonally.

[0026] There are several connecting buses 4, which are arranged on the two long sides extending along the length of the PCB board 1 and are staggered with each other. For example, the opposite side position of the connecting bus 4 in the middle of any long side is the position between the two adjacent connecting buses 4 on the opposite long side. In addition, any two adjacent connecting buses 4 on the same long side are spaced apart from each other.

[0027] The bolt 7 penetrates the connecting bus 4 and the PCB board 1 from top to bottom in sequence. The position where the bolt 7 penetrates is provided with a metal reinforcement column 6 supported between the connecting bus 4 and the PCB board 1. It should be noted that the bolt 7 is used for fastening and electrical connection between the connecting bus 4 and the PCB board 1.

[0028] The top surface of the bolt 7 is completely covered with glue 8, and the glue 8 overflows around the top surface of the bolt 7 and adheres to the connecting bus 4. That is to say, the glue 8 bonds the bolt 7 and the connecting bus 4 at the same time. In this way, the bolt 7 and the connecting bus 4 are tightened by the glue 8, making the fastening relationship between the bolt 7 and the connecting bus 4 and the PCB board 1 more secure.

[0029] The positioning lock buckle 9 is located on one side of the bolt 7 and passes through the connecting bus 4 and the PCB board 1 from top to bottom. The positioning lock buckle 9 includes a filling body 10 supported between the connecting bus 4 and the PCB board 1. The positioning lock buckle 9 also includes a positioning body 11 located in a limited abutment with the opening corresponding to the PCB board 1.

[0030] The NTC component 5 includes an NTC reinforcement plate 12 arranged on the back side of the PCB board 1. The NTC reinforcement plate 12 is connected to the NTC 14 with an NTC protective shell 15 through NTC glue 13 on the side facing the front side of the PCB board 1. A thermal pad 18 is provided on the side facing the back side of the NTC reinforcement plate 12.

[0031] The NTC pin 16 of the NTC 14 extends from the front side of the PCB board 1 to the back side of the PCB board 1 and is fastened by soldering 17 , thereby strengthening the fastening of the connection between the NTC pin 16 and the PCB board 1 .

[0032] The present application discloses a novel CCS component, which adopts a PCB board made of FR-4 material. It not only provides reliable physical support for connecting the bus, but also integrates the circuits for voltage sampling and temperature sampling, thereby realizing the integration of the FPC and the isolation board functions. This not only significantly reduces the cost of the traditional CCS solution, but also makes the overall design more compact, greatly improves the space utilization efficiency, and thus significantly enhances the energy density of the PACK; it also successfully solves the problem of difficult fixation of the FPC and aluminum bar in the traditional CCS solution, and effectively reduces the overall cost of equipment development by reducing the use of equipment and processes; it brings a new development direction to the CCS field and has broad application prospects.

[0033] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
