[0043] In the application, connecting row 20 is specifically aluminum row, and since aluminum row is made of high-strength aluminum alloy, it has the advantages of light weight, high hardness, good heat conductivity and corrosion resistance. Therefore, the aluminum row can reduce the overall weight of the CCS assembly 1, which is conducive to realizing the lightweight of the CCS assembly 1. At the same time, the aluminum row has good heat conduction performance, can effectively dissipate heat, and ensure the stable operation of the CCS assembly 1, so as to maintain the normal operation of the electric core 90. In addition, the aluminum row also has good corrosion resistance and can be used in various harsh environments, thereby improving the service life of the CCS assembly 1 and reducing the use cost of the CCS assembly 1.

[0044] In an embodiment, the CCS assembly 1 further comprises a collection member 40, the first positioning member 11 and the second positioning member 12 are provided with a plurality of second accommodating grooves 32, and the collection member 40 is arranged in the second accommodating groove 32. The collection member 40 is used to be connected with the connecting strip 20 to collect the parameters of the battery cell 90. In this way, the space on the first positioning member 11 and the second positioning member 12 is reasonably utilized, so that the collection member 40 does not need to occupy additional installation space, thereby facilitating the reduction of the overall volume of the CCS assembly 1 and the miniaturization development of the CCS assembly 1.

The temperature sensor is in contact with the surface of the connecting strip 20 to collect the temperature information of the battery cell 90. The collection member 40 is electrically connected with the temperature sensor. The collection member 40 is used to receive the temperature information collected by the temperature sensor and transmit the temperature information collected by the temperature sensor to an external assembly. The external assembly can determine whether the plurality of battery cells 90 are overheated according to the signal transmitted by the collection member 40, so as to prevent the plurality of battery cells 90 from causing fire hazards due to overheating.

[0045] In the present application, when any one or several of the plurality of battery cells 90 fail and the temperature is abnormal, the temperature sensor arranged on the connecting strip 20 can collect the temperature on the heat conduction member in real time and send the collected signal to the collection member 40, so as to timely find the abnormality of the battery module and prevent the temperature of the battery module from being too high to cause danger. In this way, only one temperature sensor electrically connected with the collection member 40 needs to be arranged on the connecting strip 20. One temperature sensor can detect the temperature abnormality of the plurality of battery cells 90 through the heat conduction member, thereby reducing the number of temperature sensors and the lines connected with the temperature sensors, and reducing the cost of the CCS assembly 1.

[0048] In an embodiment, the CCS assembly 1 further comprises a first positioning column 61, the first positioning column 61 is arranged on the first positioning plate 51 and / or the second positioning plate 53, the first positioning column 61 extends along the height direction of the battery module, the first positioning plate 51 and / or the second positioning plate 53 is provided with a first positioning hole 62 corresponding to the first positioning column 61, and the first positioning column 61 is connected with the first positioning hole 62 in a penetrating manner to limit the relative position of the first positioning plate 51 and the first fixing plate 52 and / or the second positioning plate 53 and the second fixing plate 54. In the present application, the first positioning plate 51 and the second positioning plate 53 are both provided with the first positioning column 61, and the first fixing plate 52 and the second fixing plate 54 are both provided with the first positioning hole 62 corresponding to the first positioning column 61. In this way, the installation of the first positioning plate 51 and the first fixing plate 52 and the second positioning plate 53 and the second fixing plate 54 can be facilitated, thereby improving the positioning and installation efficiency.

[0049] In an embodiment, the CCS assembly 1 further comprises a second positioning column 63, the second positioning column 63 is arranged in the first accommodating groove 31, and the connecting row 20 is provided with a second positioning hole 64 corresponding to the second positioning column 63, and the second positioning column 63 is connected with the second positioning hole 64 in a penetrating manner to limit the relative position of the connecting row 20 and the first accommodating groove 31. In this way, the connecting row 20 can be accurately positioned, thereby further improving the overall assembly efficiency of the CCS assembly 1.

[0050] In an embodiment, the first positioning plate 51 and / or the second positioning plate 53 has at least two positioning portions 13, and the at least two positioning portions 13 are sequentially connected along the circumferential direction of the battery module. In the present application, the first positioning plate 51 and the second positioning plate 53 have two positioning portions 13, and the included angle of the two positioning portions 13 is a right angle. In this way, the positioning efficiency of the CCS assembly 1 during installation can be improved as much as possible, thereby further shortening the required time during installation of the CCS assembly 1.

[0051] In an embodiment, the CCS assembly 1 further comprises a pressing member 70, the pressing member 70 is located on the side of the first fixing plate 52 and the second fixing plate 54 away from the battery cell 90 and is connected with the first fixing plate 52 and the second fixing plate 54, the pressing member 70 is provided with a pressing portion 73, and the pressing portion 73 is used for pressing and fixing the connecting row 20. In this way, the phenomenon of falling off of the connecting row 20 during use can be prevented, which is conducive to maintaining the stability of the CCS assembly 1 during operation.

[0052] In an embodiment, the pressing member 70 is further provided with a first connecting hole 71, and the first fixing plate 52 and the second fixing plate 54 are provided with a second connecting hole 72 corresponding to the connecting hole, and a fastener passes through the first connecting hole 71 and the second connecting hole 72 to fixedly connect the pressing member 70 with the first fixing plate 52 and the second fixing plate 54. In this application, the first connecting hole 71 is specifically a countersunk threaded hole. The countersunk hole can make the head of the fastener (such as a flat head screw) completely sink into the hole and be flush with the surface of the pressing member 70, thereby avoiding the protrusion of the screw head from the surface of the pressing member 70, making the overall appearance of the pressing member 70 more smooth and neat. This is particularly important for occasions that pursue exquisite appearance and process requirements. At the same time, the design of the countersunk hole provides sufficient clearance between the fastener and the surrounding components, reducing the mutual interference between the components and facilitating the placement and installation of other components. This helps to improve the overall rationality of the product layout and the convenience of use.

[0053] Further, since the countersunk hole makes the head of the fastener flush with the surface of the workpiece, it reduces the risk of touch or collision injury caused by the protrusion of the screw head. At the same time, it also reduces the protruding part on the surface of the pressing member 70, making the surface of the pressing member 70 more flat, which is beneficial to reduce the resistance of air and fluid. At the same time, the edge of the countersunk hole provides consistent edge support for the surface of the workpiece around the fastener, which helps to enhance the stability and reliability of the fastener and prevent safety hazards caused by loose fasteners.

[0054] In an embodiment, the first connecting hole 71 includes a waist-shaped hole. The design of the waist-shaped hole can effectively disperse stress, improve the durability and stability of the structure. In components that bear heavy loads or repeated loads, the waist-shaped hole can significantly enhance the strength and durability of the structure, thereby prolonging the service life of the pressing member 70. By reasonably setting the position, size and shape of the waist-shaped hole, the designer can optimize the distribution of stress and guide the stress to pass along the expected path, thereby reducing the stress concentration phenomenon in the structure. This helps to improve the overall stiffness and stability of the structure. During assembly, the waist-shaped hole can serve as a positioning reference to ensure the accurate centering of the parts, thereby simplifying the assembly process and improving the assembly efficiency. At the same time, the design of the waist-shaped hole has a certain flexibility, which can be adjusted according to actual needs to adapt to different assembly and connection requirements.

In this way, displacement of the positioning structure 10 can be prevented to ensure stable operation of the CCS assembly 1.

[0056] In an embodiment, the first fixing member 81 comprises foam. Since foam has the characteristics of light weight and low cost, the overall volume of the battery module can be further reduced.

[0057] In assembly, the components of the CCS assembly 1 can be assembled individually or preliminarily formed as a whole.

[0058] In individual assembly, the positioning portions 13 on the first positioning plate 51 and the second positioning plate 53 abut against the side surfaces of the battery cells 90 for positioning, and are fixed by the foam preliminarily adhered to the battery cells 90. Then, the first fixing plate 52 and the second fixing plate 54 are positioned by the first positioning holes 62 thereon and the first positioning plate 51 and the second positioning plate 53. Finally, the compression plate is connected to the first fixing plate 52 and the second fixing plate 54 by screw fastening, so as to compress the aluminum bars.

[0059] In overall assembly, the first positioning holes 62 are fixed to the first positioning plate 51, the second positioning plate 53, the first fixing plate 52, the second fixing plate 54 and the compression plate. Before assembly, the screws are loosened until the first fixing plate 52 and the second fixing plate 54 can move freely. Then, the positioning portions 13 abut against the side walls of the first and last battery cells 90 for positioning, and are fixed by the foam. The first positioning plate 51 and the second positioning plate 53 are fixed to the first fixing plate 52 and the second fixing plate 54 by the thin back adhesive, or are fixed by the cooperation of the first positioning columns 61 on the first positioning plate 51 and the second positioning plate 53 and the first positioning holes 62 on the first fixing plate 52 and the second fixing plate 54.
