Description

Technical Field

[0001] The utility model relates to the technical field related to batteries, and in particular to a CCS component and a battery pack. Background Art

[0002] In the battery field, especially in application scenarios such as new energy vehicles, energy storage systems, and industrial equipment, CCS components (Cells Contact System, integrated busbar) are key components of the battery system, and their stability and reliability are directly related to the performance and safety of the battery system. However, the existing CCS component design has obvious deficiencies in some aspects, especially in the layout of the sampling end and sampling harness.

[0003] At present, the sampling terminal in the battery system is usually set above the bar. This design is prone to damage when facing external pressures such as vibration and impact during the assembly, transportation or use of the battery module. Such damage may not only cause the battery management system to be unable to accurately obtain battery status information, but also may affect the safety performance of the battery and the stability of the overall system.

[0004] At the same time, the layout of the sampling harness also has similar problems. In existing designs, the sampling harness is usually exposed or simply fixed above the insulating bracket without adequate protection. During the operation of the battery system, the sampling harness is easily damaged due to temperature changes, vibrations, and possible mechanical collisions, resulting in interruption or distortion of signal transmission. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the utility model provides a CCS assembly and a battery pack, which can solve the problem that the sampling end and the sampling harness are easily damaged by pressure.

[0006] The technical solution adopted by the utility model to solve the problem is:

[0007] A CCS component, used to connect with each battery cell in a battery module, comprises: an insulating bracket, the insulating bracket comprises a fitting surface opposite to the battery cell and a free surface opposite to the fitting surface, the fitting surface is provided with a first accommodating groove, the free surface is provided with a second accommodating groove and an exhaust groove which are offset from the first accommodating groove, and a connecting port is provided between the first accommodating groove and the second accommodating groove; an electrical connection component, the electrical connection component is arranged in the second accommodating groove; a collection component, the collection component is arranged in the first accommodating groove; a sampling terminal, the sampling terminal is arranged in the connecting port, one end of the sampling terminal extends into the first accommodating groove and is connected to the collection component, and the other end extends into the second accommodating groove and is connected to the electrical connection component.

[0008] By adopting the above solution, firstly, the sampling terminal is no longer directly set at a position susceptible to external pressure, but is cleverly designed in the connecting port of the insulating bracket. This design can effectively protect the sampling terminal from the direct effect of external pressure and reduce the risk of damage; secondly, the collection component and the electrical connection component are respectively placed in the first receiving groove and the second receiving groove. This layout not only makes the installation of the components more stable, but also provides them with additional protection. During the assembly, transportation or use of the battery module, even if vibration or impact occurs, these components can remain relatively stable and safe due to the protective effect of the insulating bracket.

[0009] Furthermore, the electrical connection assembly includes a plurality of tabs, a tab assembly hole is provided in the second receiving groove corresponding to each tab, a sampling trough is provided on one side of the tab close to the insulating bracket, and one end of the sampling terminal is connected to the sampling trough.

[0010] By adopting the above scheme, the assembly hole of the bar piece is conducive to the assembly and fixation of the bar piece, and the connection stability between the sampling terminal and the electrical connection component is enhanced through the structure of the sampling trough. The installation of the sampling terminal in the sampling trough is more secure and not easily disturbed by external pressure. One end of the sampling terminal is connected to the sampling trough. Such a layout ensures good contact between the sampling terminal and the electrical connection component. Through the fixing effect of the sampling trough, the sampling terminal can maintain a stable connection state when subjected to external pressure, avoiding signal transmission problems caused by looseness or misalignment.

[0011] Furthermore, the sampling trough is arranged at the edge of the bar piece, and the sampling trough penetrates the edge of the bar piece to form a trough opening, and the opening direction of the trough opening faces the communication port.

[0012] By adopting the above scheme, the sampling trough is set at the edge of the bar, and the design of the trough opening corresponding to the connecting port is used, so that the sampling terminal can be connected to the electrical connection component more directly and efficiently. This layout reduces the path and potential interference of signal transmission, thereby improving the quality and efficiency of signal transmission. Secondly, the design of the trough opening makes the sampling terminal more convenient during installation and removal. The trough opening makes it easier to access and fix the sampling terminal, and also facilitates subsequent maintenance and replacement operations. This design improves the maintainability and scalability of the component.

[0013] Further, the bar piece includes a first bar piece, one side of which is bent to provide a first boss and a first bending portion, the first boss protruding between the first bar piece and the first bending portion in a direction away from the insulating bracket, and the first boss extending in a first direction, and the first bending portion being bent in a direction close to the insulating bracket.

[0014] By adopting the above solution, the first bending portion is conducive to making the first bar piece serve as the output pole bar piece, and the first boss can improve the self strength of the first bar piece.

[0015] Furthermore, the bar piece includes a second bar piece, and the second bar piece is symmetrically provided with two sampling sinks along the second direction, and two second bosses are provided along the first direction between the two sampling sinks.

[0016] By adopting the above solution, the second bar can serve as a connecting bar for connecting different battery modules.

[0017] Furthermore, the bar piece includes a third bar piece, and the third bar piece is symmetrically provided with two sampling sinks along the first direction, and a third boss is provided between the two sampling sinks along the second direction.

[0018] By adopting the above solution, the third bar can serve as a connecting bar between different battery cell rows in the battery module.

[0019] Furthermore, the bar piece includes a fourth bar piece, and the fourth bar piece is symmetrically provided with two sampling sinks along the second direction, and a fourth boss along the first direction is provided between the two sampling sinks.

[0020] By adopting the above solution, the fourth bar acts as two adjacent battery cells in the battery module.

[0021] Furthermore, the sampling terminal is arranged obliquely along a first direction, and a connection height between the sampling terminal and the collection component is higher than a connection height between the sampling terminal and the electrical connection component.

[0022] By adopting the above solution, the sampling terminal tilted along the first direction can ensure that during the sampling process, the signal can be transmitted to the acquisition component more directly and efficiently. Since the connection height between the sampling terminal and the acquisition component is high, the signal transmission path is relatively short, thereby reducing the possibility of signal attenuation and interference.

[0023] Furthermore, the acquisition component includes a plurality of sampling cables and a sampling output pole, the sampling output pole is located at one end of the sampling cable, and a plurality of sampling terminals are connected to the same side of the sampling cable at intervals.

[0024] By adopting the above solution, the acquisition component includes multiple sampling cables and sampling output poles, and the sampling output pole is located at one end of the sampling cable. This design enables the sampling signal to be effectively transmitted to the sampling output pole through the sampling cable, and then received and processed by the battery management system or other related equipment. The use of sampling cables also ensures the stability and reliability of signal transmission and reduces errors caused by signal interference or attenuation. Multiple sampling terminals are connected at intervals on the same side of the sampling cable. This interval connection design can avoid signal interference between the sampling terminals and ensure that each sampling terminal can independently and accurately collect the status information of the battery cell. At the same time, the side connection between the sampling terminal and the sampling cable also optimizes the overall layout, making the entire acquisition component more compact and stable.

[0025] A battery pack comprises a shell, a battery module and a CCS assembly located in the shell, wherein the battery module comprises a plurality of linearly stacked battery cells, the fitting surface of the insulating bracket faces the battery cells, the battery cells comprise poles and explosion-proof valves, the exhaust groove faces the explosion-proof valve, and the exhaust groove is provided with a plurality of through holes connected to the explosion-proof valve, the second accommodating groove faces the pole, and the second accommodating groove is provided with a plurality of through holes connected to the pole, the second accommodating groove and the exhaust groove are provided with assembly tables on both sides of the inner walls, the assembly table is equipped with a protective layer, and the protective layer is aligned with the free surface.

[0026] By adopting the above solution, by setting the first accommodating groove and the second accommodating groove on the insulating bracket, the electrical connection component and the collection component can be accommodated and protected, and a protective layer is also installed on the assembly table and aligned with the free surface. The design of the protective layer further strengthens the protection of the CCS component and prevents direct damage to the internal structure of the component by external factors.

[0027] In summary, the CCS assembly and battery pack provided by the utility model have the following technical effects:

[0028] 1. By arranging a first receiving groove for accommodating the collection component and a second receiving groove for accommodating the electrical connection component on the insulating bracket, a good working space is provided for the collection component and the electrical connection component, which can resist adverse factors such as external vibration and impact, and protect the internal electrical connection component and collection component from damage;

[0029] 2. By providing a connecting port between the first receiving slot and the second receiving slot, the access and fixation of the sampling terminal are more convenient, and the subsequent maintenance and replacement operations are also convenient; the connecting port is concealed, and the sampling terminal located inside can be protected from damage, and the status information of the battery module can be accurately and quickly collected, providing reliable data support for the battery management system, thereby ensuring the normal operation and safety performance of the battery pack;

[0030] 3. The design of the CCS component fully considers the safety requirements of the battery module. By optimizing the layout and structure of the sampling terminals and electrical connection components, the safety risks caused by poor contact or short circuit are reduced.

[0046] Embodiment 1 of the present utility model is referred to Figure 1-Figure 10As shown, a CCS component is disclosed, which is used to connect with each battery cell in a battery module 8, including an insulating bracket 1, an electrical connection component 2, a collection component 3 and a sampling terminal 4. The insulating bracket 1 includes a fitting surface 11 opposite to the battery cell and a free surface 12 opposite to the fitting surface 11. The fitting surface 11 is provided with a first accommodating groove 111, and the free surface 12 is provided with a second accommodating groove 121 and an exhaust groove 122 which are arranged offset from the first accommodating groove 111, so that the insulating bracket 1 forms a rectangular wave structure when viewed from the end. Specifically, the electric connection component 2 is set to The width direction of the battery module 8 is the first direction, and the length direction is the second direction. The length direction is also the stacking direction of the battery cells. The stacked battery cells are a battery module as a whole. In the portion of each group of battery modules 8 corresponding to the insulating bracket 1, along the first direction, the insulating bracket 1 includes the second receiving groove 121, the first receiving groove 111, the exhaust groove 122, the first receiving groove 111 and the second receiving groove 121 from one side to the other side, wherein the second receiving groove 121 faces the pole of the battery cell, and the exhaust groove 122 faces the explosion-proof valve of the battery cell. When there are multiple groups of battery modules 8, each battery module 8 is arranged along its own width direction to form a multi-column structure, and the number of the second receiving groove 121, the first receiving groove 111 and the exhaust groove 122 of the material bracket 1 also increases accordingly.

[0047] The collection component 3 includes a plurality of sampling cables 31 and a sampling output pole 32, wherein the sampling output pole 32 is located at one end of the sampling cable 31, and a plurality of sampling terminals 4 are connected to the same side of the sampling cable 31 at intervals. A connecting port 13 is provided between the first receiving slot 111 and the second receiving slot 121, the electrical connection component 2 is provided in the second receiving slot 121, the collection component 3 is provided in the first receiving slot 111, and the sampling terminal 4 is provided in the connecting port 13, for connecting the electrical connection component 2 with the collection component 3, specifically, one end of the sampling terminal 4 extends into the first receiving slot 111 and is connected to the collection component 3, and the other end extends into the second receiving slot 121 and is connected to the electrical connection component 2. The number of connecting ports 13 is twice the number of battery cells, wherein through holes are provided between the first receiving slot 111 and the battery cell, between the second receiving slot 121 and the battery cell, and between the exhaust slot 122 and the battery cell, so as to complete the structural adaptation with the battery cell. In this way, the sampling terminal 4 is no longer directly arranged at a position susceptible to external pressure, but is cleverly designed in the communication port 13 of the insulating bracket 1. This design can effectively protect the sampling terminal 4 from the direct effect of external pressure and reduce the risk of damage; secondly, the electrical connection component 2 and the collection component 3 are respectively placed in the first receiving groove 111 and the second receiving groove 121. This layout not only makes the installation of the components more stable, but also provides them with additional protection. During the assembly, transportation or use of the battery module 8, even if it encounters vibration or impact, these components can remain relatively stable and safe due to the protective effect of the insulating bracket 1.

[0048] In the present embodiment 1, the electrical connection assembly 2 includes a plurality of tabs, and a tab assembly hole 123 is provided in the second receiving groove 121 corresponding to each of the tabs, and a boss 25 is provided on the tab that bulges away from the insulating support 1, so that a sampling trough 26 is formed between the tab and the second receiving groove 121, and one end of the sampling terminal 4 is connected to the sampling trough 26. The connection stability between the sampling terminal 4 and the electrical connection assembly 2 is enhanced by the structure of the sampling trough 26. Since the boss 25 bulges away from the insulating support 1, the sampling terminal 4 is more firmly installed in the sampling trough 26 and is not easily disturbed by external pressure.

[0049] Preferably, the sampling trough 26 is arranged at the edge of the bar piece, and the sampling trough 26 penetrates the edge of the bar piece to form a trough opening 27, the opening direction of the trough opening 27 is toward the connecting port 13, the sampling trough 26 is arranged at the edge of the bar piece, and the trough opening 27 is designed to correspond to the connecting port 13, so that the sampling terminal 4 can be connected to the electrical connection component 2 more directly and efficiently. This layout reduces the path and potential interference of signal transmission, thereby improving the quality and efficiency of signal transmission. Secondly, the design of the trough opening 27 makes the sampling terminal 4 more convenient during installation and removal. Through the trough opening 27, the sampling terminal 4 can be more easily accessed and fixed, and it is also convenient for subsequent maintenance and replacement operations. This design improves the maintainability and scalability of the component.

[0050] It should be noted that in this embodiment 1, the bar piece includes a first bar piece 21, a second bar piece 22, a third bar piece 23 and a fourth bar piece 24. In other embodiments, the first bar piece 21, the second bar piece 22, the third bar piece 23 and the fourth bar piece 24 can exist separately or in any combination, which is not specifically limited here.

[0051] Specifically, the first bar 21 is mainly distributed at the starting end or the end end of the battery module 8, and is used to serve as an input pole or output pole connecting plate. Therefore, a first boss 212 and a first bending portion 211 are bent on one side of the first bar 21. The first boss 212 protrudes between the first bar 21 and the first bending portion 211 in a direction away from the insulating bracket 1, and the first bending portion 211 is used to serve as the total positive pole or total negative pole of the battery module 8. Assuming that the width direction of the battery module 8 is the first direction and the length direction is the second direction, the first boss 212 extends along the first direction, and the first bending portion 211 is bent in a direction close to the insulating bracket 1. The first boss 212 is located at the edge of the battery cell, which plays a supporting role and improves the self-strength and stability of the first bar 21.

[0052] The second bar piece 22 is mainly distributed in the battery module 8 and is used as a connecting piece to connect two groups of battery cell groups. Therefore, the second bar piece 22 is symmetrically provided with two sampling grooves 26 along the second direction, and two second bosses 221 along the first direction are provided between the two sampling grooves 26. The second bosses 221 are respectively located at the edges of the two battery cell groups to play a supporting role and improve the self strength and stability of the second bar piece 22.

[0053] The third bar piece 23 is mainly distributed on the connecting pieces between the battery cell groups arranged in parallel along the first direction. The third bar piece 23 is symmetrically provided with two sampling grooves 26 along the first direction. A third boss 231 along the second direction is provided between the two sampling grooves 26. The third boss 231 is located at the edge of the two battery cell groups to play a supporting role and improve the self strength and stability of the third bar piece 23.

[0054] The fourth bar piece 24 is mainly distributed between every two stacked battery cells in the battery cell group. The fourth bar piece 24 is symmetrically provided with two sampling grooves 26 along the second direction. A fourth boss 241 along the first direction is provided between the two sampling grooves 26. The fourth boss 241 is located at the edge of the two battery cells to play a supporting role, thereby improving the self strength and stability of the fourth bar piece 24.

[0055] In some embodiments, the first bar piece 21, the second bar piece 22, the third bar piece 23 and the fourth bar piece 24 are all provided with welding observation holes 28 for observing the assembly positions of the bar pieces and the battery cell poles.

[0056] Preferably, the sampling terminal 4 is tilted along the first direction so that the connection height between the sampling terminal 4 and the collection component 3 is higher than the connection height between the sampling terminal 4 and the electrical connection component 2. The sampling terminal 4 tilted along the first direction can ensure that during the sampling process, the signal can be transmitted to the collection component 3 more directly and efficiently, saving the length of the sampling terminal 4. Since the connection height between the sampling terminal 4 and the collection component 3 is high, the signal transmission path is relatively short, thereby reducing the possibility of signal attenuation and interference.

[0057] The utility model also relates to a battery pack, including a shell 7, a battery module 8 and a CCS component located in the shell 7, wherein the battery module 8 includes a plurality of linearly stacked battery cells, the fitting surface of the insulating support 1 faces the battery cell, the battery cell includes a pole and an explosion-proof valve, the exhaust groove 122 faces the explosion-proof valve, and the exhaust groove 122 is provided with a plurality of through holes connected to the explosion-proof valve, the second receiving groove 121 faces the pole, and the second receiving groove 121 is provided with a plurality of through holes connected to the pole, the second receiving groove 121 and the exhaust groove 122 are provided with an assembly table 5 on both sides of the inner wall, the assembly table 5 is provided with a protective layer 6, and the protective layer 6 is aligned with the free surface 12, and the first receiving groove 111 and the second receiving groove 121 are provided on the insulating support 1, so as to accommodate and protect the electrical connection component 2 and the collection component 3, and the assembly table 5 is also provided with a protective layer 6, and is aligned with the free surface 12. The design of the protective layer 6 further strengthens the protection of the CCS component and prevents direct damage to the internal structure of the component by external factors. At the same time, a pressure relief channel is formed between the protective layer 6 and the exhaust groove 122, and high-temperature and high-pressure gas can be discharged from both ends of the exhaust groove 122 to achieve pressure relief operation; when multiple groups of battery modules 8 are arranged, two adjacent second receiving grooves 121 can be combined to assemble a protective layer 6 to improve assembly efficiency. The sampling terminal 4 can also avoid the protective layer 6 by being inclined along the first direction to avoid affecting the assembly of the protective layer 6.

[0058] In summary, the CCS assembly and battery pack provided by the utility model have the following technical effects:

[0059] 1. By arranging the first receiving groove 111 for accommodating the collection component 3 and the second receiving groove 121 for accommodating the electrical connection component 2 on the insulating bracket 1, a good working space is provided for the collection component 3 and the electrical connection component 2, which can resist adverse factors such as external vibration and impact, and protect the internal electrical connection component 2 and the collection component 3 from damage;
