[0014] Furthermore, each individual battery cell has a heat transfer tube extending from its polar terminal into the outer casing, and the heat transfer tube exchanges heat with the polar terminal of each individual battery cell.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] 1. This utility model optimizes the structure of the end plate assembly of the battery component shell and provides an insulating mounting base that cooperates with the end plate assembly. The optimized shell structure of the battery component is installed in conjunction with the insulating mounting bases at both ends of the battery component to ensure the reliability of the connection between the battery component and the support frame and the insulation safety when the battery component is working.

[0017] This invention optimizes the structure of the battery component end plate assembly. A mounting groove is provided on the outer surface of the first end plate, through which the battery component engages with the insulating mounting base. The optimized end plate assembly not only facilitates the installation of the battery component but also simplifies the assembly structure between the battery component and the battery frame compared to other methods of mounting and fixing the battery component.

[0018] In addition, two insulating mounting bases are respectively set at both ends of the battery component. During the inspection of each battery component or before installation on the support frame, the insulating mounting bases can also ensure effective insulation between the battery component and the testing platform or temporary storage platform, eliminating the need for additional insulation settings on the testing platform or temporary storage platform, thus improving the safety of battery component inspection or temporary storage.

[0019] 2. To achieve reliable installation of the battery component, this utility model provides a first rib on the outer side of the first end plate of the end plate assembly, and a mounting groove on the first rib. An insulating mounting seat is also provided to mate with the end plate assembly. During use, the two insulating mounting seats are respectively installed at both ends of the battery component. The insulating mounting seats are in contact with the outer end face of the first end plate, providing a binding force in the y-direction to the battery component. Simultaneously, the first rib of the first end plate is located within the first mounting groove of the insulating mounting seat, and the mounting protrusion of the insulating mounting seat is embedded in the mounting groove of the first rib, providing binding forces in the z and x directions to the battery component. Through the above structure and mating, the insulating mounting seat can provide force to the battery component in multiple directions, achieving multi-directional positioning and installation of the battery component, ensuring that the battery component maintains a relatively stable position without movement or tilting, and guaranteeing stable and reliable operation.

[0020] 3. In the battery component assembly of this utility model, baffles are provided on both sides of the insulating mounting base. These baffles are located between the cylindrical bodies of adjacent battery components, improving the insulation performance between them even when the battery components are closely arranged. Simultaneously, the cylindrical body of the battery component has a concave-convex positioning structure extending along the y-direction. This structure is embedded into a second mounting groove on the inner side of the baffle, providing a z-direction binding force to the cylindrical body of the battery component from the insulating mounting base. After the insulating mounting base is installed at the end of the battery component, it has mounting cooperation with the end plate assembly and cylindrical body of the battery component, thereby positioning and installing the battery component through multiple areas and positions to improve the operational reliability of the battery component.

[0021] 4. In the battery component assembly of this utility model, a third rib is provided on each of the two side plates of the cylinder. The third rib can improve the strength of the cylinder. Compared with increasing the strength by increasing the wall thickness of the cylinder, the third rib not only improves the strength of the cylinder, but also reduces the amount of material used, thereby reducing the cost and weight of the cylinder. The third rib and the concave-convex positioning structure are integrally formed on the cylinder, which not only further improves the strength, but also facilitates processing and has a lower manufacturing cost.

[0022] In addition, the aforementioned concave-convex positioning structure can increase the gap between the shells of adjacent battery components, thereby increasing the insulation distance between the shells of adjacent battery components when the battery components are closely arranged, and improving the insulation performance between the battery components.

[0023] 5. In the battery component assembly of this utility model, the outer side of the upright plate of the insulating mounting base is provided with a rib plate. The insulating mounting base can be easily connected to the support frame through the mounting plate, and can be easily connected to the battery component shell through the rib plate. At the same time, the rib plate also further improves the overall strength of the insulating mounting base.

[0024] 6. In the battery component assembly of this utility model, the battery component places multiple individual batteries in a housing with a shared chamber. The shared chamber is connected to the inner cavity of each individual battery located in the housing, which reduces the differences between individual batteries and improves the consistency between individual batteries to a certain extent, thereby improving the cycle life of the battery component to a certain extent.

[0025] 7. In the battery component assembly of this utility model, the first end plate of the end plate assembly has an explosion vent for installing an explosion venting component. Through this explosion vent, the gas in the battery component can be discharged in a timely manner, avoiding excessive pressure inside the battery component's casing and potential safety hazards.

[0026] 8. In the battery component assembly of this utility model, the end plate assembly further includes a second end plate located inside the first end plate, and a gas channel is provided between the second end plate and the first end plate, the gas channel being connected to the explosion vent. When the end plate assembly is sealed and fixed to the open end of the cylinder, the gas channel of this structure has a large flow area, allowing the gas inside the battery component to be smoothly discharged through the gas channel to the explosion vent assembly of the explosion vent, further improving the safety performance of the battery component during use.

[0027] 9. In the battery component assembly of this utility model, a heat transfer tube is connected to the part of the polar terminal of each individual battery that extends out of the outer shell. The heat transfer tube exchanges heat with the polar terminal of each individual battery. A heat transfer medium flows inside the heat transfer tube. By controlling the temperature of the heat transfer medium, it can be ensured that the battery component always operates at the normal operating temperature.

[0028] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] To achieve reliable installation of the battery component, this invention optimizes the structure of the battery component, specifically by optimizing the structure of the end plate assembly of the battery component shell. At the same time, it provides an insulating mounting base that cooperates with the end plate assembly. The optimized shell structure of the battery component cooperates with the insulating mounting bases at both ends of the battery component, so that the insulating mounting bases can position and install the battery component in multiple directions, thereby ensuring the reliability of the battery component during operation.

[0046] The aforementioned battery components can be existing battery packs or battery modules, or they can be high-capacity batteries. The battery packs or modules described herein can consist of a casing and multiple individual cells connected in parallel or series within the casing. The high-capacity batteries described herein are batteries composed of multiple individual cells connected in parallel with a shared electrolyte system. The structure of such high-capacity batteries can be found in the high-capacity battery structures disclosed in CN220797038U, CN117878492A, CN220324596U, CN118299739A, CN220324640U, and CN118800999A.

[0047] The aforementioned battery components may also consist of a housing and multiple electrode assemblies located within the housing. These electrode assemblies are commonly used in the battery industry and are components within the casing of a single battery cell, rather than being understood as the single battery cell itself. Furthermore, they may be wound cores or cells made by stacking. Generally, the electrode assembly includes at least a positive electrode, a separator, a negative electrode, and tabs connected to the positive and negative electrode respectively.

[0048] For ease of description, the width direction of the outer shell is defined as the x-direction, the length direction of the outer shell is defined as the y-direction, and the height direction of the outer shell is defined as the z-direction.

[0049] This invention optimizes the structure of the end plate assembly of the battery component shell and provides an insulating mounting base that mates with the end plate assembly. The optimized shell structure of the battery component mates with the insulating mounting bases at both ends of the battery component to ensure the reliability of the connection between the battery component and the support frame, as well as the insulation safety, when the battery component is in operation.

[0050] This invention optimizes the structure of the battery component end plate assembly. A mounting groove is provided on the outer surface of the first end plate, through which the battery component engages with the insulating mounting base. The optimized end plate assembly not only facilitates the installation of the battery component but also simplifies the assembly structure between the battery component and the battery frame compared to other methods of mounting and fixing the battery component.

[0051] In addition, two insulating mounting bases are respectively set at both ends of the battery component. During the inspection of each battery component or before installation on the support frame, the insulating mounting bases can also ensure effective insulation between the battery component and the testing platform or temporary storage platform, eliminating the need for additional insulation settings on the testing platform or temporary storage platform, thus improving the safety of battery component inspection or temporary storage.

[0052] Example 1

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a battery component assembly, which includes a battery component 1 and an insulating mounting unit. The insulating mounting unit includes two insulating mounting seats 2, which are respectively installed at both ends of the battery component 1. The battery component 1 is mounted on a support frame 3 via the insulating mounting seats 2 at both ends. When the battery component 1 is in use, the two insulating mounting seats 2 not only position and install the battery component 1, but also ensure that the outer shell of the battery component 1 does not contact the support frame 3, thus achieving insulation between each battery component 1 and the support frame 3 and improving the safety of the battery component 1 during use.

[0054] like Figure 3 As shown, the battery component 1 in this embodiment includes a housing and a plurality of individual batteries 13 arranged in the housing along the y-direction; the housing includes a cylindrical body 12 with open ends and two end plate assemblies 11 respectively sealed and fixed to the open ends of the cylindrical body 12. Figure 4 As shown, the end plate assembly 11 in this embodiment includes a first end plate 111, which is a flat plate structure. Since the first end plate 111 is used to seal the open end of the cylindrical body 12 of the battery component 1, the shape of the first end plate 111 is adapted to the shape of the open end of the cylindrical body 12. The area of ​​the first end plate 111 can be slightly larger than the area of ​​the open end of the cylindrical body 12, or it can be the same as the area of ​​the open end of the cylindrical body 12. Specifically, the first end plate 111 can be fixed to the open end of the cylindrical body 12 by welding. Of course, other methods can also be used to fix the first end plate 111 to the open end of the cylindrical body 12. After connection, the sealing between the first end plate 111 and the cylindrical body 12 must be ensured.

[0055] Furthermore, if the cylindrical body 12 of the battery component 1 also has a shared chamber, then the first end plate 111 also has a structure for sealing the shared chamber. For example, Figure 3 The top plate of the cylinder 12 of the battery component 1 has a gas sharing chamber 126. Correspondingly, the top of the first end plate 111 needs to have a protruding sub-end plate structure. The shape of the sub-end plate matches the cross-sectional shape of the gas sharing chamber 126. The gas sharing chamber 126 of the cylinder 12 is sealed by the protruding sub-end plate.

[0056] Based on the above structure, this embodiment optimizes the structure of the first end plate 111. The optimized structure not only improves the strength of the first end plate 111, but also enables reliable installation of the battery component 1. The specific optimized structure is as follows:

[0057] In this embodiment, a mounting groove 113 facing the inner cavity of the battery component is provided on the outer side of the first end plate 111 away from the inner cavity of the battery component. The battery component mates with the insulating mounting seat through the mounting groove 113. The structure of this end plate assembly not only facilitates reliable installation of the battery component, but also simplifies the structure of the battery component. Compared with other methods of installing and fixing the battery component, the method of providing the mounting groove 113 facilitates the processing and manufacturing of the battery component's outer shell, and also reduces the manufacturing cost of the battery component.

[0058] This embodiment can further optimize the structure of the end plate assembly, such as... Figure 4 As shown, the outer surface of the first end plate 111 has at least one first rib 112 extending along the z-direction. After the first rib 112 is provided on the first end plate 111, a mounting groove 113 can be provided on the first rib 112, and the mounting groove 113 penetrates the first rib 112 in the x-direction. Each first rib 112 protrudes from the outer surface of the first end plate 111. The outer surface of the first end plate 111 is the side of the first end plate 111 away from the open end of the cylinder 12. Correspondingly, the inner surface of the first end plate 111 is the side of the first end plate 111 facing the open end of the cylinder 12. In this embodiment, the number of first ribs 112 is not required, but there must be at least one. If there are multiple first ribs 112, the multiple first ribs 112 are arranged along the x-direction and are parallel. When the battery component's casing uses this end plate assembly, the first ribs 112 can not only increase the overall strength of the first end plate 111, but also ensure the safety of the battery component during use. Meanwhile, the first rib can also cooperate with the insulating mounting bases at both ends of the battery component to achieve reliable installation of the battery component.

[0059] like Figure 4 As shown, the outer side of the first end plate 111 in this embodiment has four first ribs 112. Each first rib 112 is a strip-shaped protrusion extending along the z direction. There are no requirements for the cross-section of the strip-shaped protrusion. In this embodiment, the cross-section of the strip-shaped protrusion is rectangular. In other embodiments, it can also be a semi-circular structure.

[0060] In specific manufacturing, the first rib 112 can be integrally formed onto the first end plate 111, or it can be processed separately and then fixed onto the first end plate 111 by welding or other methods. Compared to the structure of processing separately and then connecting, the first rib 112 being integrally formed onto the first end plate 111 is the preferred method. Integral forming not only further improves the strength of the first end plate 111, but also facilitates the processing of the first end plate 111, resulting in a lower manufacturing cost for the first end plate 111.

[0061] like Figure 4As shown, at least one first rib 112 in this embodiment is provided with a mounting groove 113. The mounting groove 113 penetrates the first rib 112 in the x-direction. If multiple first ribs 112 are provided with mounting grooves 113, the height of the mounting grooves 113 on each first rib 112 is the same, that is, the mounting grooves 113 on each first rib 112 are at the same height in the z-direction. Meanwhile, the depth of the mounting groove 113 can be the same as, less than, or greater than the thickness of the first rib 112. If it is greater than the thickness of the first rib 112, it may affect the strength of the first end plate 111. In this embodiment, the depth of the mounting groove 113 is the same as the thickness of the first rib 112, which ensures the strength of the first end plate 111 as much as possible while also facilitating the fabrication of the mounting groove 113.

[0062] In this embodiment, a first rib 112 is provided on the outer side of the first end plate 111. The first rib 112 can increase the overall strength of the first end plate 111. At the same time, an installation groove 113 is provided on the first rib 112, so that the first end plate 111 can be installed and cooperated with the insulating mounting base 2 through the first rib 112 and the installation groove 113, thereby improving the reliability of the battery component 1 during use.

[0063] To ensure reliable installation of the battery component 1 on the insulating mounting base 2, in this embodiment, the structure of the insulating mounting base 2 is adapted to the outer shell structure of the battery component 1, while also achieving insulation between the battery component 1 and the support frame. For example... Figure 2 , Figure 5 and Figure 6 As shown, the insulating mounting base 2 in this embodiment includes a support plate 21 that contacts the bottom of the cylinder 12 and a vertical plate 22 that contacts the first end plate 111. The support plate 21 ensures that the bottom plate of the cylinder 12 of the battery component 1 does not contact the support frame 3, and the size of the support plate 21 meets the creepage distance requirements between the cylinder 12 and the support frame 3. The vertical plate 22 ensures that the first end plate 111 of the battery component 1 does not contact the support frame 3, and the size of the vertical plate 22 ensures the creepage distance requirements between the first end plate 111 and the support frame 3.

[0064] like Figure 5As shown, to achieve mating installation with the first end plate 111, the inner side of the upright plate 22 of the insulating mounting base 2 has at least one mounting protrusion 24. The position and number of the mounting protrusion 24 match the position and number of the mounting grooves 113 on the first end plate 111. The thickness of the mounting protrusion 24 is less than or equal to the groove depth of the mounting groove 113 on the first end plate 111, so that after the mounting protrusion 24 is embedded into the first mounting groove 23, the outer side of the first end plate 111 is in close contact with the inner side of the upright plate 22 of the insulating mounting base 2. After the mounting protrusion 24 is embedded into the first mounting groove 23, the insulating mounting base 2 can provide a binding force in the z-direction to the first end plate 111 to position the battery component 1 in the z-direction.

[0065] In this embodiment, the inner side of the upright plate 22 of the insulating mounting base 2 has at least one first mounting groove 23 extending along the z direction. The number of first mounting grooves 23 is the same as the number of first ribs 112 on the first end plate 111. Taking the number of first ribs 112 as an example, the corresponding number of first mounting grooves 23 on the insulating mounting base 2 is four. The four first mounting grooves 23 are arranged along the x direction.

[0066] The dimensions of the first mounting groove 23 must match the dimensions of the first rib 112 so that the first rib 112 can be embedded into the first mounting groove 23. Specifically, the depth of the first mounting groove 23 is slightly greater than the thickness of the first rib 112, and the width of the first rib 112 is the same as the width of the first mounting groove 23, or the width of the first mounting groove 23 is slightly greater than the width of the first rib 112. After the first rib 112 is embedded into the first mounting groove 23, the insulating mounting base 2 can provide a binding force in the x-direction to the first end plate 111 to position and install the battery component 1 in the x-direction.

[0067] In addition, in this embodiment, the first end plate 111 can be fixedly connected to the insulating mounting base 2 to further fix the position of the battery component 1 and improve the installation reliability of the insulating mounting base 2 on the battery component 1.

[0068] In specific installation, the insulating mounting base 2 can be fixedly installed to the outer side of the first end plate 111; however, this method will affect the strength of the first end plate 111. Therefore, preferably, the insulating mounting base 2 is fixedly connected to the first rib 112 of the first end plate 111. At this time, as... Figure 4As shown, a mounting hole 114 for fixed connection with the insulating mounting base 2 can be provided on the first rib 112. This mounting hole 114 can be a threaded hole or a through hole. When a threaded hole is used, the insulating mounting base 2 is fixed to the first rib 112 of the first end plate 111 by screws. When a through hole is used, the insulating mounting base 2 is fixedly connected to the first rib 112 by screws or other connectors using adhesive or other methods. It should be noted that the position of the mounting hole 114 should preferably avoid the position of the mounting groove 113, that is, the mounting hole 114 should be located where the first rib 112 does not have a mounting groove 113, to ensure the strength of the first end plate 111. If the position of the mounting hole 114 coincides with the mounting groove 113, the first end plate 111 needs to be thicker to meet the connection requirements, and the screws in the mounting hole 114 will also affect the fit between the mounting groove 113 and the mounting protrusion 24 of the insulating mounting base 2.

[0069] like Figure 6 As shown, in this embodiment, the outer side of the upright plate 22 of the insulating mounting base 2 is also provided with a mounting plate 27. The outer side of the upright plate 22 is the side of the upright plate 22 away from the inner cavity of the battery component 1. The mounting plate 27 is a horizontal plate, which is located above the side beam of the support frame 3 during use, mainly to realize the fixed connection between the insulating mounting base 2 and the support frame 3. Specifically, the mounting plate 27 has a first connecting hole 28, and the connecting bolt passes through the first connecting hole 28 to fix it to the side beam of the support frame 3. To facilitate the connection, the first connecting hole 28 can be an oblong hole. The oblong hole can adjust the installation position of the insulating mounting base 2 in the x direction, which can compensate for the installation error between the insulating mounting base 2 and the support frame 3 and ensure the reliability of the connection. In addition, the mounting plate of the insulating mounting base 2 also has an avoidance notch for the passage of the explosion venting pipe of the battery component. The explosion venting pipe is a pipe connected to the explosion venting assembly of the battery component and is used for the directional discharge of gas in the battery component.

[0070] like Figure 6 As shown, the outer side of the upright plate 22 of the insulating mounting base 2 in this embodiment is also provided with a rib plate 29. The rib plate 29 mainly realizes the fixed connection between the insulating mounting base 2 and the first end plate 111. The number of rib plates 29 is set according to the requirements. In this embodiment, there are four rib plates 29. Each rib plate 29 is perpendicular to the mounting plate 27 and fixed to the mounting plate 27. At least one rib plate 29 has a second connecting hole 210 that connects to the first end plate 111. The connecting screw passes through the second connecting hole 210 to realize the connection with the first rib 112.

[0071] In this embodiment, the insulating mounting base 2 is made of insulating material, specifically reinforced nylon (PA66 and glass fiber), which ensures insulation while also providing a certain installation strength. Furthermore, during manufacturing, the support plate 21, upright plate 22, mounting plate 27, rib plate 29, and baffle plate 25 of the insulating mounting base 2 are all integrally formed to ensure reliability during use.

[0072] In this embodiment, the end plate assembly of the outer casing is structurally optimized. The optimized end plate assembly cooperates with the insulating mounting seats at both ends of the battery component. After the insulating mounting seats 2 are installed at both ends of the battery component 1, the outer side of the first end plate 111 is in close contact with the insulating mounting seats 2, and the insulating mounting seats 2 provide a binding force in the y direction to the battery component 1. The first rib 112 of the first end plate 111 is located in the first mounting groove 23 of the insulating mounting seat 2, and the mounting protrusion 24 in the first mounting groove 23 is embedded in the mounting groove 113 of the first rib 112. At this time, the insulating mounting seat 2 provides binding forces in the z and y directions to the battery component 1, so that the insulating mounting seat 2 provides binding forces or forces to the battery component 1 in multiple directions, thereby providing positioning for the battery component in multiple directions, realizing the positioning and installation of the battery component 1 in multiple directions, so as to achieve reliable installation of the battery component.

[0073] Example 2

[0074] This embodiment provides a battery component assembly. This embodiment further optimizes the structure of the battery component and the insulating mounting base 2. When optimizing the battery component, the structure of the cylindrical body 12 of the battery component 1 is specifically optimized.

[0075] like Figure 7 As shown, in this embodiment, the cylinder 12 is an open cylinder with open ends on both the left and right sides (i.e., the two ports parallel to the xz plane are open ends). The cylinder 12 includes a top plate, a bottom plate, and two side plates 121. The cylinder 12 is a rectangular cylinder made of metal material. In order to facilitate processing and production, the cylinder 12 can be made by integral molding. Integral molding methods include casting, extrusion, 3D printing, etc. Considering both cost and processing efficiency, this embodiment selects extrusion process to form the cylinder 12.

[0076] like Figure 7 As shown, in this embodiment, the two side plates 121 of the cylindrical body 12 are respectively provided with concave-convex positioning structures 122. Each concave-convex positioning structure 122 extends along the y-direction and is a strip-shaped protrusion structure. The concave-convex positioning structure 122 can cooperate with the insulating mounting base 2 to further position and install the battery component 1 in the z-direction, thereby improving the installation reliability of the battery component 1.

[0077] In addition, in this embodiment, the two side plates 121 of the cylinder 12 are respectively provided with third ribs 123, and each third rib 123 extends along the y direction. The third ribs can improve the strength of the cylinder. Compared with increasing the strength by increasing the wall thickness of the cylinder, the third ribs not only improve the strength of the cylinder, but also reduce the amount of material used in the cylinder, thereby reducing the cost and weight of the cylinder.

[0078] Both the third rib and the concave-convex positioning structure are integrally molded onto the cylinder body, which not only further enhances the strength but also facilitates processing and reduces manufacturing costs. The third rib 123 and the concave-convex positioning structure 122 can further increase the strength of the outer shell and improve the safety of the battery component 1. During manufacturing, the concave-convex positioning structure 122 and the third rib 123 can be integrally molded onto the cylinder body 12, specifically through an extrusion process. This manufacturing method not only further enhances the strength but also facilitates processing and reduces manufacturing costs.

[0079] like Figure 5 and Figure 6 As shown, in this embodiment, baffles 25 are also provided on both sides of the insulating mounting base 2, and the end face of each baffle 25 is parallel to the yz plane. After the insulating mounting base 2 is fitted onto the end of the battery component 1, the baffles 25 are located between the outer shells of adjacent battery components 1, which can improve the insulation reliability between adjacent battery components 1 when the battery components 1 are closely arranged. At the same time, the baffles 25 can also position the battery component 1 in the x direction, further improving the installation reliability of the battery component 1.

[0080] In addition, each baffle 25 has a second mounting groove 26 extending in the y direction on its inner side surface. The position of the second mounting groove 26 corresponds to the position of the concave-convex positioning structure 122 on the side plate 121 of the cylinder 12. After the insulating mounting seat 2 is installed at both ends of the battery component 1, the concave-convex positioning structure 122 of the cylinder 12 is embedded into the second mounting groove 26 on the inner side surface of the baffle 25. The insulating mounting seat 2 positions and installs the battery component 1 in the z direction, further realizing the reliable installation of the battery component 1.

[0081] Example 3

[0082] like Figure 3 and Figure 8 As shown, this embodiment provides a battery component assembly, and the structure of battery component 1 is further optimized in this embodiment.

[0083] In this embodiment, the battery component 1 includes a housing and multiple individual batteries 13 arranged in the same direction within the housing. The individual batteries 13 are prismatic batteries, and their number can be adjusted according to actual needs. The inner cavity of each individual battery 13 includes an electrolyte area and a gas area. After the multiple individual batteries 13 are arranged in the same direction within the housing, a clearance hole 125 is provided on the top plate of the housing corresponding to the polarity terminal 131 of each individual battery 13. The polarity terminal 131 of each individual battery 13 extends out of the corresponding clearance hole 125 as the polarity terminal 131 of the battery component 1 (the polarity terminals of all individual batteries on one side serve as the positive polarity terminal of the battery component, and the polarity terminals of all individual batteries on the other side serve as the negative polarity terminal of the battery component). The area of ​​the top plate of the housing corresponding to the clearance hole 125 is fixedly sealed to the housing of the individual battery 13.

[0084] It should be noted that the polarity terminal 131 of the single cell 13 here can be the terminal post of the single cell 13. In order to prevent the terminal post of the single cell 13 from not being able to extend smoothly out of the clearance hole 125 as the polarity terminal 131, a terminal post adapter can be connected to the terminal post of the single cell 13, and the overall structure of the terminal post of the single cell 13 and the terminal post adapter can be used as the polarity terminal 131 of the single cell 13.

[0085] The aforementioned outer casing has a shared chamber, the inner cavity of which is connected to the inner cavities of all individual battery cells 13.

[0086] like Figure 7 As shown, the aforementioned shared chamber can be an electrolyte shared chamber 127. The inner cavity of the electrolyte shared chamber 127 is connected to the electrolyte area inside all individual battery cells 13. Through the electrolyte shared chamber 127, each individual battery cell 13 can be in a uniform electrolyte environment, ensuring the uniformity of the electrolyte in each individual battery cell 13 and improving the performance and charge-discharge cycle life of the battery component 1. In this embodiment, the electrolyte shared chamber 127 is a liquid channel disposed between the bottom plate of the outer casing and the bottom of each individual battery cell 13.

[0087] The aforementioned shared chamber can also be a gas-sharing chamber 126. The inner cavity of the gas-sharing chamber 126 is connected to the gas region of the inner cavity of all individual battery cells 13. The gas balance of each individual battery cell 13 is achieved through the gas-sharing chamber 126, which can also improve the performance of the battery component 1 and its charge-discharge cycle life. In this embodiment, the gas-sharing chamber 126 is a gas channel 116 provided on the top plate of the outer casing. At this time, the top plate of the outer casing has a protrusion extending along the arrangement direction of the individual battery cells 13, and the gas channel 116 is formed at the protrusion.

[0088] The aforementioned shared chamber can also be a gas-liquid shared chamber. The inner cavity of the gas-liquid shared chamber is connected to the electrolyte area and gas area of ​​all individual battery cells 13. Through a gas-liquid shared chamber, each individual battery cell 13 can be in a unified electrolyte environment and gas environment, which improves the performance of the battery component 1 and its charge-discharge cycle life.

[0089] like Figure 8As shown, to further improve the safety of the battery component 1 during use in this embodiment, a heat transfer pipe 15 is connected to the portion of the polar terminal 131 of each individual battery 13 that extends out of the outer casing. The heat transfer pipe 15 exchanges heat with the polar terminal 131 of each individual battery 13. When the temperature of the battery component 1 is higher than a set threshold, the battery component 1 is cooled by introducing a lower temperature heat transfer medium into the heat transfer pipe 15. When the temperature of the battery component 1 is lower than the set threshold, the battery component 1 is heated by introducing a higher temperature heat transfer medium into the heat transfer pipe 15. By controlling the temperature of the heat transfer medium, it can be ensured that the battery component 1 always operates at the normal operating temperature.

[0090] like Figure 3 and Figure 8 As shown, the top of the outer shell of the battery component 1 has two heat transfer tubes 15, each extending along the y-axis and arranged along the x-axis. Each polarity terminal 131 of the battery component 1 has a through groove. The two heat transfer tubes 15 are respectively embedded in the through grooves of the polarity terminals 131 located on different sides. One heat transfer tube 15 is embedded in the through groove of the positive polarity terminal 131 of the battery component 1, and the other heat transfer tube 15 is embedded in the through groove of the negative polarity terminal 131 of the battery component 1. The heat transfer tube 15 has a channel for the heat transfer medium to pass through, and heat exchange is performed on the polarity terminals 131 of the battery component 1 through the heat transfer tube 15.

[0091] Meanwhile, in this embodiment, an insulating sealant layer is laid on the top plate of the outer casing. The insulating sealant layer covers at least a portion of the structure of the heat transfer tube 15 and the polar terminal 131, with the top of the heat transfer tube 15 exposed, serving as an electrical connection. During the operation of the battery component 1, internal temperature changes may cause water vapor condensation. The insulating sealant layer can isolate external moisture, reduce internal humidity changes, and prevent water droplets from forming on the surfaces of the heat transfer tube 15 and the polar terminal 131, thus preventing short circuits and component corrosion caused by condensation. In addition, covering a portion of the structure of the heat transfer tube 15 and the polar terminal 131 within the sealant layer makes the connections between components tighter, reducing relative displacement between components under conditions such as vibration and impact, and enhancing the structural stability of the entire battery component 1.

[0092] Furthermore, because the polarity terminal 131 of the individual battery 13 is directly exposed to the external environment, there is a significant safety hazard during use due to the energized polarity terminal 131. Therefore, if... Figure 2 As shown, in this embodiment, an insulating protective cover 16 is provided on the outside of the battery component 1 to provide insulation protection for the polar terminals 131 of the individual battery 13. The insulating protective cover 16 avoids the potential safety hazards of the individual battery 13 polar terminals 131 being exposed during the operation of the battery component 1, and also avoids the problem of foreign objects from the external environment falling into the position of the individual battery 13 polar terminals 131 and causing a short circuit in the battery component 1, thereby improving the safety of the battery component 1.

[0093] like Figure 8 and Figure 9 As shown, in order to draw the thermal runaway flue gas out of the outer shell of the battery component 1, the first end plate 111 of the end plate assembly 11 has a vent 117. When the end plate assembly 11 is sealed and fixed to the open end of the cylinder 12, the vent 117 is connected to the inner cavity of the battery component 1. Through the vent 117, the gas in the battery component 1 can be discharged in time, so as to avoid the high pressure inside the outer shell of the battery component 1 and the occurrence of safety hazards.

[0094] In addition, the vent 1 can also have other uses, such as serving as an operating port for a package opening device or as an injection port for liquid injection.

[0095] An explosion vent assembly 14 can be installed on the aforementioned explosion vent 117. The explosion vent assembly 14 can be a hollow component with an explosion vent membrane at one end, or it can be a structure such as an explosion vent valve. To facilitate the installation of the explosion vent assembly 14, the explosion vent 117 is located in the area of ​​the first end plate 111 where the first rib 112 is not provided, and is preferably located in the middle area of ​​the first end plate 111.

[0096] In this embodiment, the explosion vent 117 of the battery component casing is provided with an explosion vent assembly 14 that communicates with the shared chamber. The explosion vent assemblies 14 of adjacent battery components 1 are connected to form an explosion vent manifold. When a single cell 13 in any battery component 1 experiences thermal runaway, the thermal runaway fumes can be discharged through the explosion vent manifold, reducing the risk of combustion or explosion of the battery component 1.

[0097] like Figure 9 and Figure 10 As shown, the end plate assembly 11 may also be provided with a gas channel 116. The gas channel 116 is connected to the shared chamber of the outer casing, and the explosion vent 117 is connected to the gas channel 116. The gas inside the outer casing of the battery component 1 is smoothly discharged through the gas channel 116 to the explosion vent assembly 14 of the explosion vent 117, thereby achieving reliable explosion venting. The gas channel 116 can be implemented in the following ways:

[0098] First, the gas channel 116 is a groove provided on the inner side of the first end plate 111. The groove extends along the z direction and is connected to the inner cavity of the outer shell and the explosion vent 117 to realize the discharge of gas. This method requires the first end plate 111 to have a corresponding thickness to set the groove.

[0099] Second, a second rib is added to the inner side of the first end plate 111, and the gas channel 116 is formed by the second rib provided on the inner side of the first end plate 111; at the same time, the second rib can also further increase the overall strength of the first end plate and improve the reliability of the battery component during use.

[0100] Third, such as Figure 9 and Figure 10 As shown, a second end plate 115 is added inside the first end plate 111. There is a gap between the second end plate 115 and the first end plate 111. This gap is a gas channel 116. This arrangement of the gas channel 116 makes the gas channel 116 have a large flow area.

[0101] Furthermore, adding a second end plate 115 inside the first end plate 111 can improve the overall strength of the end plate assembly 11. At the same time, in the y-direction, the second end plate 115 can also clamp the individual cells 13 inside the housing, improving the stability of each individual cell 13 within the housing cavity and preventing the problem of reduced cycle performance of the battery component 1 due to swelling of the individual cells 13.

[0102] In use, two insulating mounting bases 2 are installed at both ends of the battery component 1. The inner side of the upright plate 22 of the insulating mounting base 2 is in close contact with the outer side of the first end plate 111. The insulating mounting base 2 provides a binding force in the y-direction to the battery component 1. The first rib 112 is located in the first mounting groove 23, and the mounting protrusion 24 in the first mounting groove 23 is embedded in the mounting groove 113 of the first rib 112. At this time, the insulating mounting base 2 provides binding forces in the z-direction and x-direction to the battery component 1. At the same time, the insulating mounting base 2 can be fixedly connected to the first rib 112 to further fix the position of the battery component 1. Subsequently, the battery component 1 with the insulating mounting base 2 is placed on the support frame 3, and the insulating mounting base 2 is fixedly connected to the support frame 3.

[0103] When the insulating mounting base 2 is fixed on the support frame, it secures each battery component 1 from multiple angles, preventing movement or tilting and ensuring stable and reliable operation of the battery component 1. Simultaneously, the insulating mounting base 2 also ensures that the outer casing of the battery component 1 does not contact the support frame 3, achieving insulation between each battery component 1 and the support frame 3, thus improving the insulation reliability and safety of the battery component 1 during use.

[0104] To further improve the insulation between the battery component 1 and the support frame 3, the insulation mounting unit may also include an insulating pad 4 located inside the support frame 3. The insulating pad 4 improves the insulation performance between the battery component 1 and the support frame 3. The insulating pad 4 can be made of PP board, ABS board, or electrical board, etc. The insulating pad 4 is located inside the side beam extending along the y-direction of the support frame 3, achieving insulation between the outermost battery component 1 cylinder 12 and the support frame 3. At the same time, each insulating pad 4 also has a third mounting groove that cooperates with the concave-convex positioning structure 122 of the battery component 1 cylinder 12. The concave-convex positioning structure 122 of the outermost battery component cylinder 12 is embedded in the third mounting groove, which also improves the installation stability of the battery component 1.
