[0070] like Figure 3-Figure 8 As shown, the CCS assembly 10 according to the first embodiment of the utility model comprises: an isolation plate 11 and a connecting member 12. The isolation plate 11 is a blister piece. The isolation plate 11 is Figure 4 The connecting member 12 is connected to the isolation plate 11 and is arranged on the side where the first surface of the isolation plate 11 is located. The connecting member 12 is used to electrically connect the poles of the battery cell.

[0071] The CCS assembly 10 can also be called a CCS integrated busbar. CCS is the abbreviation of Cells Contact System, which means an integrated busbar. The CCS assembly 10 is mainly composed of a signal acquisition assembly, a plastic structural member, and a copper-aluminum busbar. The CCS assembly 10 is connected into a whole through processes such as hot pressing or riveting to achieve high-voltage series and parallel connection of battery cells and temperature sampling and voltage sampling functions of battery cells. The signal acquisition assembly can be a traditional acquisition harness or a flexible circuit board. The plastic structural member is used to electrically connect multiple battery cells. In this embodiment, the plastic structural member is an isolation plate 11.

[0072] In this embodiment, the isolation plate 11 is configured as a blister, which is a product made by a blister process. The blister process is a molding technology that uses thermoplastic plastic sheets as molding objects. After the sheets are cut into a required size, they are heated and softened, and then vacuum-adsorbed on the mold surface and cooled to form the required product. In this embodiment, the isolation plate 11 can be made of polypropylene material and formed by blister.

[0073] The connector 12 is used to electrically connect the battery cells. The number of connectors 12 can be determined according to the number of battery cells in the battery 100, and the arrangement of the connectors 12 on the isolation plate 11 can also be set accordingly according to the arrangement of the battery cells. The connector 12 can be made of a metal material such as aluminum. In this embodiment, the connector 12 is connected to the isolation plate 11 and is arranged on the first surface of the isolation plate 11. The connector 12 and the isolation plate 11 can be connected by a snap connection, a hot riveting connection, a bolt fixing, etc. The connector 12 can be a connecting plate, and the connector 12 and the isolation plate 11 can form a connection mating surface.

[0074] In this embodiment, the isolation plate 11 is set as a blister, which makes the isolation plate 11 more convenient and easy to produce. Compared with the production and processing by injection molding, the mold opening cycle of the isolation plate 11 is shorter, the yield is higher, and the production efficiency is higher, thereby greatly reducing the production cost of the CCS assembly 10. In this embodiment, the connector 12 is set to meet the needs of electrical connection of multiple battery cells.

[0075] It can be understood that the battery cell is provided with a shell, which is generally made of a metal material with conductive properties. The pole portion of the battery cell protrudes from the shell. In this embodiment, the connector 12 is arranged on the first surface of the isolation plate 11. When the connector 12 is electrically connected to the pole, the isolation plate 11 can play a good role in separating the connector 12 and the shell of the battery cell, thereby reducing the risk of short circuit of the battery 100.

[0076] According to the CCS component 10 of the embodiment of the utility model, by setting the isolation plate 11 and the connecting piece 12, the isolation plate 11 is set as a blister piece, so that the production efficiency of the isolation plate 11 can be higher and the cost can be saved, thereby greatly improving the production efficiency of the CCS component 10 and greatly reducing the production cost of the CCS component 10.

[0078] There may be multiple wire harnesses 13, each of which may have different collection functions. For example, the wire harness 13 may include a low-voltage sampling wire harness, a high-voltage sampling wire harness, a temperature sampling wire harness, etc. The wire harness 13 extends on the first surface, that is, the wire harness 13 and the connector 12 are located on the same side surface in the thickness direction of the isolation plate 11. When the wire harness 13 is routed on the isolation plate 11, it can be routed according to the arrangement of the connector 12 to avoid the connector 12, for example Figure 3 As shown, the connectors 12 are arranged in two rows, and the wiring harness 13 can be routed in the area of ​​the isolation plate 11 between the two rows of connectors 12 and connected to the connectors 12 .

[0079] The wire harness 13 can be restrained and fixed on the first surface of the isolation plate 11 by means of snapping, bonding or binding, and the collecting end 131 of the wire harness 13 and the connector 12 can be connected by welding to form an electrical connection.

[0080] In this embodiment, a wiring harness 13 is provided, which has a simple structure and can meet the needs of collecting battery cell information in the battery 100. Arranging the wiring harness 13 and the connector 12 on the same side of the isolation plate 11 can facilitate the connection and arrangement of the wiring harness 13 and the connector 12 on the isolation plate 11, and the isolation plate 11 can play a good role in separating the wiring harness 13 and the battery cell, so that the connection between the CCS assembly 10 and the battery cell when assembled in the battery 100 is more convenient and reliable.

[0081] In one embodiment of the present invention, Figure 3 As shown, the CCS assembly 10 may further include: a binding member 14 , through which the wire harness 13 is bound to the isolation plate 11 .

[0082] After the wire harness 13 is arranged on the isolation plate 11, the binding piece 14 can bind the wire harness 13 on the isolation plate 11, and the number of the binding pieces 14 can be set according to the need to fix the routing direction of the wire harness 13. The binding piece 14 can be a cable tie, and the material of the binding piece 14 can be nylon, stainless steel, sprayed stainless steel, etc., and the cable tie can be a retractable cable tie, a latch type cable tie, etc.

[0083] In this embodiment, a binding member 14 is provided to fix the wire harness 13 on the isolation plate 11, which has a simple structure and is firmly and stably fixed.

[0084] In some examples of the present invention, Figure 3-Figure 8 As shown, a hole group may be provided on the isolation plate 11 , the hole group includes two through holes 112 arranged at intervals, and one end of the binding member 14 passes through the two through holes 112 of the hole group and is connected to the other end of the binding member 14 to bind the wiring harness 13 between the two through holes 112 .

[0085] The perforations 112 may be circular holes, rectangular holes, waist-shaped holes, etc. The shape and size of the perforations 112 may be set according to the cross-sectional shape or maximum cross-sectional area of ​​the binding member 14. The spacing between the two perforations 112 may be set according to the total cross-sectional area of ​​the wire harness 13 to be bound. For example, when there are more wire harnesses 13 between the two perforations 112, the spacing between the two perforations 112 may be set larger. When there are fewer wire harnesses 13 between the two perforations 112, the spacing between the two perforations 112 may be set smaller. Of course, the spacing between the two perforations 112 may also be set to a fixed value to simplify the design of the perforations 112. After the binding member 14 binds and fixes the wire harness 13, the side of the wire harness 13 facing the isolation plate 11 may be pressed against the first surface of the isolation plate 11.

[0086] In this embodiment, a hole group is provided on the isolation plate 11, which can facilitate the binding and fixing of the wire harness 13 on the isolation plate 11 by the binding member 14. The hole group has a simple structure and is easy to process, making it convenient and easy to fix the wire harness 13 on the isolation plate 11.

The spacing between the hole groups can be set accordingly according to the fixing requirements of the wire harness 13, for example, the spacing between the hole groups can prevent the wire harness 13 from bulging after being tied and fixed.

[0089] In the present embodiment, a plurality of hole groups are provided, and the binding members 14 correspond to the hole groups one by one, so that the wire harness 13 can be stably and reliably bound and fixed to the isolation plate 11 through the plurality of binding members 14 in the length direction thereof, with a simple structure and convenient and reliable fixing.
