Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a CCS component and battery pack. Background Technology

[0002] In the field of power battery module integration, the CCS (Cells Contact System) module, as the core component of the battery cell connection system, typically includes an insulating support, an FPC component fixed on the insulating support, and a pad fixed on the insulating support.

[0003] In practical applications, the insulating support typically has several terminal slots located directly below the battery pack, through which the terminals of the individual battery cells in the battery module can extend. After the terminal of the individual battery cell passes through the corresponding terminal slot, it can connect to the bottom surface of the battery pack.

[0004] To achieve lightweight design, CCS components are typically thermoformed. Thermoformed components have low structural strength, especially after several pole slots are opened, the area between two adjacent pole slots is prone to breakage.

[0005] Therefore, existing CCS components need to be improved to address the problem of easy breakage in the area between two adjacent pole slots.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a CCS component and battery pack that can effectively solve the problem of easy breakage in the area between two adjacent pole slots.

[0008] To achieve the above objectives, on the one hand, this utility model provides a CCS assembly, including an insulating support, a plurality of FPC components fixed on the insulating support, and a plurality of bar sheet assemblies fixed on the insulating support;

[0009] in,

[0010] The insulating support is provided with several downwardly recessed tab receiving grooves, and the periphery of the tab receiving grooves forms support reinforcing ribs. The tab receiving grooves have openings facing the FPC component, and the bottom of the tab receiving grooves away from the openings are provided with several pole post through grooves.

[0011] A groove bottom reinforcement structure is provided between two adjacent pole posts through the groove;

[0012] The electrode assembly is disposed at the bottom of the electrode receiving groove, and is connected to the FPC component at one end near the opening, while the other end away from the opening is used to connect to the terminal post of the battery module.

[0013] Optionally, the groove bottom reinforcement structure includes upwardly protruding structural reinforcement ribs and / or downwardly recessed structural reinforcement grooves.

[0014] Optionally, the groove bottom reinforcement structure is a downwardly recessed structural reinforcement groove;

[0015] The plaster assembly has a downwardly recessed plaster reinforcement portion that extends into the structural reinforcement groove at the position corresponding to the structural reinforcement groove.

[0016] Optionally, each of the FPC components is provided with a plurality of the flap receiving grooves on both sides, and the flap receiving grooves are provided with at least one apex corner away from the corresponding FPC component as a foolproof chamfer.

[0017] The tab assembly corresponds to the top corner of the anti-fool chamfer, and its shape and size match the corresponding anti-fool chamfer to expose part of the pole post through the groove.

[0018] Optionally, the bottom of the plaster receiving groove is provided with an upwardly protruding hot riveting post;

[0019] The plate assembly is provided with a rivet hole for the hot riveting post to pass through.

[0020] Optional,

[0021] The FPC component is provided with a data acquisition branch that corresponds one-to-one with each of the blister pack components;

[0022] The electrode assembly includes a conductive electrode for connection to an electrode post, and a acquisition plate electrically connecting the conductive electrode to the corresponding acquisition branch.

[0023] Optionally, one end of the acquisition piece extends to the bottom surface of the conductive bar, and the other end extends to the top surface of the corresponding acquisition branch, and is electrically connected to the FPC component;

[0024] The acquisition branch is equipped with a thermistor, which is thermally connected to the acquisition chip and electrically connected to the FPC component.

[0025] Optionally, the bottom of the slab receiving groove is provided with a clearance groove to accommodate the collection slab.

[0026] Optionally, the distance from the edge of the pole through groove to the wall of the bar plate receiving groove is greater than zero.

[0027] On the other hand, a battery pack is provided, including a battery housing, a battery module located within the battery housing, and any of the aforementioned CCS components electrically connected to the battery module.

[0028] The beneficial effects of this utility model are as follows: It provides a CCS component and battery pack, which fundamentally improves the problem of weak structural strength of the vacuum-formed insulating bracket by setting a reinforcing structure (bracket reinforcing rib + slot bottom reinforcing structure) between two adjacent pole slots and setting the electrode assembly in the electrode receiving slot, thereby increasing the contact area between the electrode assembly and the bottom of the electrode receiving slot.

[0029] On the one hand, when the insulating bracket is manufactured using vacuum forming, the design of the pole slot will reduce the material at the bottom of the slot, resulting in a narrow connection area between adjacent slots. This area is prone to cracking due to stress concentration when the battery module vibrates or is subjected to assembly stress.

[0030] The added bottom reinforcement structure in this invention directly acts on this mechanically weak area, achieving structural strengthening by changing the local geometry. This structural design cleverly utilizes the forming characteristics of vacuum forming—the bottom reinforcement structure can be integrally formed with the battery pack receiving groove in the mold, creating a reinforced unit with specific mechanical properties on the thin-walled vacuum-formed part without additional processes. When the battery module is running, the alternating stress generated by vibration is dispersed and absorbed by the bottom reinforcement structure, preventing stress from continuously accumulating at the edge of the electrode slot, thereby effectively preventing the initiation and propagation of cracks, and ultimately solving the problem of easy fracture in the area between two adjacent electrode slots within the same battery pack receiving groove.

[0031] On the other hand, the reinforcing ribs of the bracket can improve the structural strength of the periphery of the slab receiving groove, thereby solving the problem that the area between two adjacent poles in different slab receiving grooves is prone to breakage.

[0032] Therefore, the CCS component and battery pack provided by this utility model can effectively solve the problem of easy breakage in the area between two adjacent pole slots. Attached Figure Description

[0048] This utility model provides a CCS module and battery pack, which is suitable for lightweight CCS modules in power battery modules. By setting a groove bottom reinforcement structure between adjacent pole slots, it solves the problem that the insulating bracket formed by vacuum forming is prone to stress concentration and breakage due to insufficient structural strength.

[0049] The battery pack provided in this embodiment includes a battery housing, a battery module located inside the battery housing, and a CCS component electrically connected to the battery module.

[0050] A battery module comprises multiple closely packed battery cells. A battery cell is the smallest unit in a battery pack where electrochemical reactions occur, and can be either a secondary or primary battery. Battery cells can be lithium-ion, lithium-sulfur, sodium-ion, or magnesium-ion batteries, but are not limited to these types. Battery cells can be cylindrical, flat, cuboid, or other shapes.

[0051] In some embodiments, the battery cell includes a housing, an end cap, terminals, and an electrode assembly. The housing and the end cap together form an internal space for accommodating the battery cell. Specifically, the housing may have a cavity with at least one open end, the end cap may be closed at the open end of the housing to seal the cavity, the electrode assembly may be mounted within the cavity, and the terminals may be disposed on the end cap and electrically connected to the electrode assembly inside the housing through the end cap. The housing may be, but is not limited to, a metal housing, such as an aluminum housing or a steel housing.

[0052] The CCS component provided in this embodiment will be described in detail below.

[0053] See Figure 1 The CCS assembly provided in this embodiment includes an insulating support 1, a plurality of FPC components 2 fixed on the insulating support 1, and a plurality of battery pack assemblies 3 fixed on the insulating support 1 and used for electrically connecting the FPC components 2 to the battery module.

[0054] See Figure 2 The insulating support 1 is provided with several downwardly recessed pad receiving grooves 101, and the periphery of the pad receiving grooves 101 forms support reinforcing ribs 108. The pad receiving grooves 101 have openings 109 facing the FPC component 2, and the bottom of the pad receiving grooves 101 away from the openings 109 is provided with several pole post through grooves 102.

[0055] A groove bottom reinforcement structure 103 is provided between two adjacent pole post through grooves 102;

[0056] The ferrule assembly 3 is disposed at the bottom of the ferrule receiving groove 101, and is connected to the FPC component 2 at one end near the opening 109, and connected to the terminal post of the battery module at the other end away from the opening 109.

[0057] The CCS component and battery pack provided in this embodiment improve the problem of weak structural strength of the vacuum-formed insulating bracket 1 by setting a reinforcing structure (bracket reinforcing rib 108 + groove bottom reinforcing structure 103) between two adjacent pole slots 102 and setting the pad assembly 3 in the pad receiving groove 101, thereby increasing the contact area between the pad assembly 3 and the bottom of the pad receiving groove 101.

[0058] On the one hand, when the insulating bracket 1 is manufactured using vacuum forming process, the design of the pole slot 102 will reduce the material at the bottom of the slot, resulting in a narrow connection area between adjacent slots. This area is prone to cracking due to stress concentration when the battery module vibrates or is subjected to assembly stress.

[0059] The newly added bottom reinforcement structure 103 in this invention directly acts on this mechanically weak area, achieving structural reinforcement by changing the local geometry. This structural design cleverly utilizes the molding characteristics of vacuum forming—the bottom reinforcement structure 103 can be integrally formed with the battery pack receiving groove 101 in the mold, forming a reinforcement unit with specific mechanical properties on the thin-walled vacuum-formed part without adding extra processes. When the battery module is running, the alternating stress generated by vibration will be dispersed and absorbed by the bottom reinforcement structure 103, preventing stress from continuously accumulating at the edge of the terminal post through groove 102, thereby effectively preventing the initiation and propagation of cracks, and ultimately solving the problem of easy fracture in the area between two adjacent terminal post through grooves 102 within the same battery pack receiving groove 101;

[0060] On the other hand, the reinforcing rib 108 of the bracket can improve the structural strength of the periphery of the blister packing groove 101, thereby solving the problem that the area between two adjacent pole column through grooves 102 in different blister packing grooves 101 is prone to breakage.

[0061] In addition, the electrode receiving groove 101 extends from the end near the opening 109 to the end away from the opening 109, thereby reducing the cross-sectional area of ​​the electrode through groove 102, thus reducing the problem of easy breakage in this area, while maximizing the contact area between the bottom of the electrode receiving groove 101 and the electrode assembly 3, thereby improving the overall strength of the CCS assembly.

[0062] Therefore, the CCS module and battery pack provided by this utility model can effectively solve the problem of easy breakage in the area between two adjacent pole slots 102, and at the same time improve the overall strength of the CCS module and ensure the reliability of the CCS module.

[0063] In this embodiment, the bracket reinforcing rib 108 can surround three sides of the tablet receiving groove 101, and the opening 109 can be provided on one side of the tablet receiving groove 101. Thus, the opening 109 and the bracket reinforcing rib 108 together form the tablet receiving groove 101, thereby maximizing the strength of the pole through groove 102 area. The opening 109 can be used to connect the tablet assembly 3 to the FPC component 2, and also facilitates the installation of the tablet assembly 3.

[0064] It is understood that the groove bottom reinforcement structure 103 may include upwardly protruding structural reinforcing ribs and / or downwardly recessed structural reinforcing grooves. Specifically, by providing upwardly protruding reinforcing ribs or downwardly recessed reinforcing grooves, the structural stiffness between adjacent pole posts passing through the groove 102 is enhanced by utilizing geometric changes. The reinforcing ribs improve bending resistance by increasing the local material thickness, while the reinforcing grooves reduce the risk of stress concentration by optimizing the stress distribution path.

[0065] Specifically, in this embodiment, in order to improve the stability of the installation of the plaster assembly 3, the groove bottom reinforcement structure 103 is a downwardly recessed structural reinforcement groove; further, the plaster assembly 3 is provided with a downwardly recessed plaster reinforcement part 3011 that extends into the structural reinforcement groove at the position corresponding to the position of the structural reinforcement groove.

[0066] refer to Figure 1 The reinforcing portion 3011 of the battery module 3 and the structural reinforcing groove of the insulating support 1 form a complementary interlocking structure, which not only enhances the connection stability between the battery module 3 and the insulating support 1, but also minimizes the overall thickness of the CCS module, improves structural compactness, and increases space utilization. The downwardly recessed reinforcing portion 3011 in its thickness direction not only enhances its own strength, but also provides a certain buffering capacity to prevent the battery module 3 from breaking due to the expansion of the battery cells in the battery module.

[0067] In this embodiment, each FPC component 2 is provided with a plurality of plaster receiving grooves 101 on both sides, and at least one apex of the plaster receiving groove 101 away from the corresponding FPC component 2 is a foolproof chamfer 104.

[0068] The tab assembly 3 corresponds to the apex corner of the anti-foolproof chamfer 104, and its shape and size match the corresponding anti-foolproof chamfer 104 to expose a portion of the electrode post through groove 102. During the manufacturing process, assembly and disassembly tools can be inserted into the exposed portion of the electrode post through groove 102 to perform assembly and disassembly operations on the tab assembly 3. This matching can include the tab assembly 3 having the same angle as the anti-foolproof chamfer 104, or the angles can be different, as long as a portion of the electrode post through groove 102 is exposed.

[0069] The anti-foolproof chamfer 104 at the top corner of the basalt receiving groove 101 has a dual function: on the one hand, it prevents the basalt assembly 3 from being installed in reverse through asymmetrical geometric features, and on the other hand, it reduces weight by removing local materials while maintaining the structural integrity of the groove edge.

[0070] Optionally, the bottom of the pad receiving groove 101 is provided with an upwardly protruding hot riveting post 105; the pad assembly 3 is provided with a riveting post hole for the hot riveting post 105 to pass through. The mating structure of the hot riveting post 105 and the riveting post hole realizes the physical locking between the pad assembly 3 and the insulating bracket 1, avoiding the aging problem of traditional adhesive bonding process.

[0071] Optionally, the FPC component 2 is provided with a collection branch 201 corresponding to each of the electrode assembly 3. The electrode assembly 3 includes a conductive electrode 301 for contacting the electrode post, and a collection piece 302 electrically connecting the conductive electrode 301 to the corresponding collection branch 201. The collection branch is electrically connected to the wiring on the FPC component 2 and is located on one or both sides of the FPC component 2, specifically in an S-shape, to provide buffer space along the extension direction of the FPC component 2 and perpendicular to that extension direction. One end of the collection piece 302 can be electrically connected to the conductive electrode 301 (e.g., soldered), and the other end can be electrically connected to the collection branch 201 (e.g., soldered), thereby transmitting the collected voltage signal from the conductive electrode 301 to an external management system through the wiring layout of the FPC component 2.

[0072] Furthermore, one end of the acquisition piece 302 extends to the bottom surface of the conductive bar 301, and the other end extends to the top surface of the corresponding acquisition branch 201. By extending one end of the acquisition piece 302 to the bottom surface of the conductive bar 301, space on the top surface of the conductive bar 301 can be saved, improving space utilization. In this embodiment, the bottom of the bar receiving groove 101 is provided with a clearance groove 106 for accommodating the acquisition piece 302. The clearance groove 106 provides dedicated accommodating space for the acquisition piece 302, avoiding structural interference between the acquisition piece 302 and the insulating bracket 1, while also constraining the installation position of the acquisition piece 302, ensuring electrical connection stability and maintaining the consistency of the overall thickness of the component. At the same time, by setting the clearance groove 106, it is convenient for the acquisition piece 302 to connect with the bottom surface of the conductive bar 301.

[0073] In other embodiments, one end of the acquisition piece 302 may also extend to the top surface of the conductive bar 301 to improve the connection convenience between the acquisition piece 302 and the conductive bar 301.

[0074] In this embodiment, the conductive pad 301 is a large aluminum sheet, and the collecting pad 302 is a small nickel sheet.

[0075] The acquisition branch 201 is equipped with a thermistor 202, which is thermally connected to the acquisition chip 302 and electrically connected to the FPC component 2. Specifically, the thermistor 202 can be disposed on the acquisition chip 302, thereby achieving thermal connection with it. To further improve thermal conductivity, thermally conductive adhesive can be applied to the thermistor 202, covering it and connecting it to the acquisition chip 302. The bottom of the thermistor 202 can pass through the acquisition chip 302 and be electrically connected to the acquisition branch 201 to transmit the acquired temperature signal through the acquisition branch 201.

[0076] The thermistor is directly integrated onto the FPC component 2, and the layered connection design between the conductive pad 301 and the acquisition plate 302 simplifies the acquisition path for temperature and voltage signals. Simultaneously, the material properties of the aluminum pad and the nickel acquisition plate 302 are utilized to balance conductivity and cost. Optionally, the distance from the edge of the electrode slot 102 to the wall of the pad receiving slot 101 is greater than zero. The continuous support structure retained at the edge of the electrode slot 102 forms an edge reinforcement band 107, preventing the risk of tearing due to excessively thin material at the slot edge, while also providing circumferential support for the pad assembly 3, improving the deformation resistance of the electrode connection area.

[0077] In summary, the CCS component and battery pack provided in this embodiment have at least the following advantages:

[0078] ① A groove bottom reinforcement structure (groove bottom reinforcement structure + support reinforcement rib) is set between adjacent pole post grooves 102 to enhance the structural rigidity through geometric shape, disperse vibration stress, and prevent cracks from forming in the vacuum forming part.

[0079] ② The tab assembly 3 and the insulating support 1 are complemented and fitted together by the tab reinforcement part 3011 and the structural reinforcement groove, which improves the connection stability and maintains the low thickness design of the assembly.

[0080] ③ The top corner of the 101 receiving slot adopts a foolproof chamfer 104 design, which prevents reverse installation through asymmetrical geometric features, while reducing local weight to maintain the integrity of the slot structure.

[0081] ④ The data acquisition plate 302 is arranged below the conductive bar plate 301, which optimizes the spatial layout, reduces the height of the components, and improves the volumetric energy density of the battery pack.

[0082] ⑤ A clearance groove 106 is provided at the bottom of the plate receiving groove 101 to accommodate the collection plate 302, avoid structural interference and constrain the installation position, and ensure electrical stability and thickness consistency.

[0083] ⑥ The edge of the pole through the groove 102 retains a continuous support structure to form an edge reinforcement band 107, which prevents the groove from tearing and provides circumferential deformation-resistant support.

[0084] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
