Technical Field

[0001] This utility model belongs to the field of batteries, specifically a battery pack installation platform and a battery pack. Background Technology

[0002] Currently, with the continuous growth of global energy demand and the increasing awareness of environmental protection, energy storage technology has gradually become one of the important means to solve energy problems.

[0003] Energy storage devices are widely used in power systems, transportation, aerospace, and other fields due to their advantages such as portability, flexibility, and high efficiency. Existing energy storage devices on the market consist of a housing, a support frame inside the housing, and multiple battery components fixed to the support frame. During the use of these battery components, their installation and stability are crucial; reliably securing multiple battery components to the support frame is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This utility model provides a battery pack installation platform and a battery pack. Based on the battery pack installation platform, battery components can be reliably fixed on the support frame, thereby improving the structural stability of the battery pack.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A battery pack mounting platform is disclosed. The battery pack includes N battery components arranged along the x-direction. Each battery component includes a housing and multiple individual batteries disposed within the housing. At least one mounting lug is provided at each end of the housing, where N is an integer greater than 1. The mounting platform includes a support frame, an insulation component, and two pressure plates. The support frame mainly consists of two first side beams extending along the x-direction and two second side beams extending along the y-direction. The first and second side beams provide binding forces in the y and x directions to the N battery components. The insulation component includes multiple first insulating pads disposed on the first side beams and second insulating pads disposed inside the second side beams. Each first insulating pad mainly consists of a vertical plate located inside the first side beam and a plug-in plate folded over the top of the first side beam. The plug-in plate has a plug-in groove for inserting the battery component mounting lugs. The two pressure plates extend along the x-direction and are fixedly connected to the first side beams of the support frame. The pressure plates and the first side beams clamp and fix the plug-in plates of the multiple first insulating pads, thereby providing binding forces in the z-direction to the N battery components to fix each battery component onto the support frame.

[0007] Furthermore, the first insulating pad has a Z-shaped structure and also includes a support plate connected to the bottom of the vertical plate. The support plate is in contact with the bottom of the battery component housing, and the bottom end face of the support plate away from the vertical plate is provided with a protruding ridge to increase the creepage distance.

[0008] Furthermore, baffles are provided on both sides of the first insulating pad, and the end face of each baffle is parallel to the yz plane.

[0009] Furthermore, an insulating buffer pad extending in the x-direction is provided between the support frame and the plug plate of the first insulating pad.

[0010] Furthermore, the first side beam has an L-shaped structure. The vertical plate of the first side beam provides binding force in the y-direction, and the horizontal plate provides support for each battery component in the z-direction. At the same time, the bottom of the horizontal plate has multiple strip-shaped protrusions.

[0011] Furthermore, the first and second side beams of the support frame are fixedly connected by welding.

[0012] Furthermore, the pressure plate has a downwardly bent edge.

[0013] This utility model also provides a battery pack, which includes N battery components and a battery pack mounting platform; each battery component includes a housing and multiple individual batteries arranged in the housing along the y-direction; each of the two end plates of the housing is provided with mounting ears, and the end plates are parallel to the xz plane; the N battery components are arranged sequentially on a support frame along the x-direction, and the support frame provides binding forces in the y and x directions to the N battery components; first insulating pads are respectively installed at both ends of the battery components, and the mounting ears at both ends of the battery components are respectively embedded in the insertion slots of the insertion plate; a pressure plate fixes the insertion plate of the first insulating pad on a first side beam, providing binding forces in the z-direction to the N battery components; at the same time, the first insulating pad and the second insulating pad of the insulating assembly achieve insulation between each battery component and the support frame.

[0014] Furthermore, there is an insulating liner between the outer casings of adjacent battery components.

[0015] Furthermore, the outer casing has a shared chamber; the inner cavity of the shared chamber is connected to the inner cavities of all individual batteries; the top plate of the outer casing has clearance holes corresponding to the polarity terminals of each individual battery; the polarity terminals of each individual battery extend out of the clearance holes, and the area of ​​the top plate of the outer casing corresponding to the clearance holes is fixedly sealed to the individual battery casing; the outer casing has a venting pipe assembly connected to the shared chamber, and the venting pipe assemblies of adjacent battery components are connected by pipes to form a venting manifold.

[0016] Furthermore, each individual cell's polar terminal is provided with a heat transfer tube extending out of the outer casing. The heat transfer tube exchanges heat with the polar terminal of each individual cell. An insulating sealant layer is laid on the top of the outer casing, and at least part of the structure of the polar terminal and the heat transfer tube is located within the insulating sealant layer.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. This utility model's battery pack installation platform can reliably install each battery component. During installation, N battery components are arranged sequentially along the x-direction on a support frame. The support frame provides binding forces in the y and x directions to the N battery components. First insulating pads are fitted onto both ends of each battery component. Pressure plates fix the plug-in plates of the first insulating pads onto the first side beam, providing binding forces in the z-direction to the N battery components. During the use of the battery components, this installation platform fixes each battery component on the support frame from multiple angles to ensure that the battery components can work stably and reliably.

[0019] Especially when this installation platform is used in mobile charging vehicles, the first insulating pad provides force to the battery component in multiple directions (x, y, and z) during the vehicle's movement. This allows the battery component to be positioned in all three directions, maintaining a relatively stable position and preventing movement or tilting, thus ensuring stable operation. Particularly in complex road conditions, the installation platform provides continuous and stable support and reliable installation for the battery component, protecting its internal structure and connections, preventing shaking and vibration, and guaranteeing its normal operation.

[0020] This battery pack mounting platform uses first and second insulating pads in the insulation components to ensure that the battery component housings do not contact the support frame, thereby achieving insulation between each battery component and the support frame and improving the insulation reliability and safety of the battery components during use. Furthermore, the battery pack mounting platform simplifies battery component installation; only the pressure plates need to be fixed during installation, saving installation time and simplifying the installation process.

[0021] 2. In the battery pack installation platform of this utility model, the first insulating pad also includes a support plate connected to the bottom of the vertical plate. The support plate extends a first side beam in the horizontal direction, further ensuring that the outer shell of each battery component does not contact the support frame, thereby improving insulation reliability and the safety of the battery components. Simultaneously, the portion of the support plate extending beyond the support frame is provided with a protruding ridge. This ridge increases the creepage distance between the battery component and the support frame, ensuring insulation performance while minimizing the size of the support plate of the first insulating pad and reducing manufacturing costs.

[0022] 3. In the battery pack installation platform of this utility model, baffles are respectively provided on both sides of the first insulating pad. The baffles are located between the outer shells of adjacent battery components, which can improve the insulation performance between adjacent battery components when the battery components are closely arranged. At the same time, the baffles can also limit the battery components in the x-direction, further improving the installation reliability of the battery components.

[0023] 4. In the battery pack installation platform of this utility model, there is also an insulating buffer pad between the plug plate of the first insulating pad and the support frame. This insulating buffer pad can not only further improve the insulation performance between the support frame and the battery components, but also press the plug plates of each first insulating pad plug plate as firmly as possible on the top surface of the support frame, thereby improving the installation reliability of the first insulating pad. In addition, the insulating buffer pad can also adjust the height of each battery component in the z direction to ensure that the height of each battery component is consistent, which facilitates the connection of electrical connections, heat transfer pipes and flue gas pipes between each battery component.

[0024] 5. In the battery pack installation platform of this utility model, the first side beam of the support frame has an L-shaped structure, which can support the battery components through the cross plate of the first side beam, improving the support stability and strength. Furthermore, strip-shaped protrusions are provided at the bottom of the two first side beams. These protrusions reduce the friction during support frame installation, facilitating the installation and disassembly of the battery pack. Simultaneously, these strip-shaped protrusions also increase the support strength of the support frame. Moreover, compared to a support frame with rollers, these strip-shaped protrusions reduce the height of the support frame, increasing the energy density of the battery pack.

[0025] 6. The first and second side beams of the battery pack installation platform support frame of this utility model are fixedly connected by welding. Compared with other connections, the welding connection improves the connection strength between the two, thereby enhancing the strength and support stability of the support frame.

[0026] 7. In the battery pack installation platform of this utility model, the pressure plate has a downward folded edge. The folded edge structure can increase the strength of the pressure plate and increase the stability of the connection.

[0027] 8. In the battery pack of this utility model, the battery component places multiple individual batteries in a shell with a shared chamber. The shared chamber is connected to the inner cavity of each individual battery located in the shell, 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.

[0028] 9. In the battery pack 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 components always operate at the normal operating temperature.

[0029] 10. In the battery pack of this utility model, there is also an insulating liner between the shells of adjacent battery components. The insulating liner can not only further ensure the insulation between adjacent battery components, but also has a certain deformation when each battery component is installed, which facilitates the installation of the battery components.

[0030] 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

Detailed Implementation

[0043] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0045] In this specification, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate component, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0046] Furthermore, in the description of this utility model, it should be noted that the terms "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0047] This utility model provides a battery pack installation platform for supporting and fixing multiple battery components that constitute the battery pack. The battery components can be existing battery packs or battery modules, or high-capacity batteries. The battery packs or modules can consist of a casing and multiple individual batteries connected in parallel or series within the casing. The high-capacity batteries described here are batteries composed of multiple individual batteries connected in parallel with a shared electrolyte system. The structure of such high-capacity batteries can be detailed in CN220797038U, CN117878492A, CN220324596U, CN118299739A, CN220324640U, and CN118800999A.

[0048] To facilitate the installation of multiple battery components, CN118659085A discloses a battery pack bracket assembly. This bracket assembly mainly consists of a support member and two L-shaped brackets. The support member is placed at the bottom of the battery pack to support it. The L-shaped brackets include a first bracket and a second bracket, wherein the first bracket is parallel to the yz plane and the second bracket is parallel to the xy plane. The first brackets of the two L-shaped brackets are respectively fixed at both ends of the support member, and the second brackets are respectively used to fix the frame opposite to the battery pack support frame. The support member includes two support ribs, which are respectively inserted into two channels at the bottom of the battery pack to support it. The support ribs and the channels are insulated from each other by a thermoplastic tube sleeved on the support ribs.

[0049] The aforementioned battery pack is equivalent to the battery component in this application. The following description uses the battery component instead of the aforementioned battery pack to describe the bracket assembly structure. In the above scheme, when installing each battery component, it is first necessary to stably fix the battery component to the support frame using L-shaped brackets fixed to both ends of the support component. Then, the bracket assembly is fixed to the support frame, making the battery component installation process relatively complex. Furthermore, when installing each bracket assembly with the battery component, the bracket assembly structure must be compatible with the structure at the bottom of the battery component, thus requiring corresponding design of the bracket assembly structure, making the bracket assembly structure relatively complex as well. In addition, the above structure also requires additional insulation measures to achieve insulation between the battery component and the bracket assembly.

[0050] This utility model provides a battery pack installation platform, which includes a support frame, an insulating component, and two pressure plates; each battery component has a mounting ear on its outer shell. During installation, N battery components are arranged sequentially on the support frame along the x-direction. The support frame provides binding forces in the y-direction and x-direction to the N battery components. First insulating pads are fitted onto both ends of each battery component. The pressure plates fix the plug plates of the first insulating pads onto the first side beam, providing binding forces in the z-direction to the N battery components. During the use of the battery components, the installation platform fixes each battery component on the support frame from multiple angles to ensure that the battery components can work stably and reliably.

[0051] Two first insulating pads are respectively fitted onto both ends of the battery components, and are fixed to the support frame by pressure plates. After installation, the first insulating pads provide binding forces in the x, y, and z directions to secure each battery component to the support frame. Simultaneously, the battery pack mounting platform uses the first and second insulating pads of the insulating assembly to ensure that the outer shell of the battery components does not contact the support frame, thus achieving insulation between the battery components and the support frame, improving the insulation reliability and safety of the battery components during use. Furthermore, the battery pack mounting platform simplifies battery component installation; only the pressure plates need to be fixed during installation, saving installation time and simplifying the installation process. After installation, the entire battery pack has a simple and compact structure, high stability, and high energy density.

[0052] This installation platform ensures the stability of battery components on the support frame during battery pack use, enabling reliable operation of each component. Especially when used in mobile charging vehicles, the platform provides restraint forces to the battery components in multiple directions (x, y, and z) during movement, maintaining their relatively stable position and preventing movement or tilting. Particularly in complex road conditions, the platform provides continuous and stable support and reliable installation of the battery components, protecting their internal structure and connections, preventing shaking and vibration, and ensuring normal operation.

[0053] Example 1

[0054] like Figure 1 As shown, this embodiment provides a battery pack installation platform 1, which is used to support N battery components 2 in the battery pack, where N is an integer greater than 1. Typically, multiple battery components 2 are arranged sequentially to form a cuboid structure. For ease of description, the direction in which the multiple battery components 2 are arranged is defined as the x-direction, the height direction of the battery components 2 is defined as the z-direction, and the direction perpendicular to both the x-direction and the z-direction is defined as the y-direction.

[0055] In this embodiment, the battery component 2 includes a housing 21 and a plurality of individual batteries 22 disposed within the housing 21. Mounting ears 211 are respectively provided on two end plates of the housing 21 parallel to the xz plane. That is, the mounting ears 211 are located on the end faces of the housing 21 parallel to the xz plane, and the number of mounting ears 211 is at least one. Figure 1 In the battery component 2, each end plate has two mounting ears 211, each mounting ear 211 protruding from the end plate of the outer casing 21 and extending in the xy plane. In specific manufacturing, the mounting ears 211 can be integrally manufactured with the end plate of the outer casing 21, or they can be processed separately and then fixed to the end plate of the outer casing 21 by welding or other methods.

[0056] like Figure 2 and Figure 3 As shown, the battery pack installation platform 1 provided in this embodiment includes a support frame 11, two pressure plates 13, and an insulation component. The support frame 11 is used to support N battery components 2 in the battery pack and to provide binding forces in the y and x directions to the N battery components. The insulation component includes a first insulating pad 12 and a second insulating pad 15, which mainly realizes the insulation between the battery components 2 and the support frame 11. At the same time, the first insulating pad 12 and the pressure plate 13 cooperate to provide binding forces in the z direction to the N battery components.

[0057] like Figure 3 and Figure 4 As shown, the battery pack formed by multiple battery components 2 arranged sequentially in the horizontal direction has a cuboid structure. To accommodate this battery pack shape, the support frame 11 in this embodiment is a rectangular frame, mainly composed of two first side beams 111 and two second side beams 112. Each first side beam 111 extends along the x-direction, and each second side beam 112 extends along the y-direction. The two first side beams 111 and two second side beams 112 are arranged at intervals and connected end-to-end to form a rectangular frame structure. Specifically, the first side beams 111 and second side beams 112 can be assembled into a rectangular frame by welding or screwing. In this embodiment, the first side beams 111 and second side beams 112 are fixedly connected by welding. Compared to other connections, welding increases the connection strength, thereby improving the strength and support stability of the support frame.

[0058] After the first side beam 111 and the second side beam 112 form the support frame 11, they need to be able to support the battery components 2. That is to say, the first side beam 111 and the second side beam 112 are L-shaped structures, and the inner sides of the first side beam 111 and the second side beam 112 need to have inwardly extending support structures so that the battery components 2 can be placed in the support frame 11. For example, if the first side beam 111 and the second side beam 112 are made of U-shaped steel, square steel or I-beam steel, etc., an internal support structure needs to be added to support each battery component 2.

[0059] To increase the stability and support strength of the support frame 11, the first side beam 111 and the second side beam 112 can also be formed by combining various types of steel, for example, square steel and angle steel. In this embodiment, considering cost and structural strength, the second side beam 112 can be made of angle steel, and the first side beam 111 can be formed by combining square steel and angle steel. When using a combined structure, the angle steel is located on the inside, and the vertical plate of the angle steel is connected to one of the vertical plates of the square steel. At the same time, a connecting hole for fixing the pressure plate 13 is machined on the top plate of the square steel. This combination can not only meet the support function of the support frame 11 without the need for additional support structural components, but also make the entire support frame 11 have good support strength.

[0060] In addition, such as Figure 4 As shown, in this embodiment, multiple strip-shaped protrusions 113 are provided at the bottom of the two first side beams 111. These protrusions 113 extend from the bottom of the first side beams 111, reducing the friction area of ​​the support frame 11 during installation, thereby reducing friction and facilitating the installation and removal of the battery pack. Simultaneously, the strip-shaped protrusions 113 also increase the support strength of the support frame 11. Furthermore, compared to the support frame 11 with mounting rollers, the strip-shaped protrusions 113 reduce the height of the support frame 11, increasing the energy density of the battery pack. In specific manufacturing, the strip-shaped protrusions 113 can be made of wear-resistant materials to improve installation reliability.

[0061] As described above, the support frame 11 is generally made of structural steel. To further ensure the safety of each battery component 2 during use, insulation between the support frame 11 and each battery component 2 is required. In this embodiment, an insulating assembly is provided between the support frame 11 and the battery component 2 to achieve the aforementioned insulation. The insulating assembly in this embodiment includes a plurality of first insulating pads 12 disposed on the first side beam 111 and a second insulating pad 15 disposed on the inner side of the second side beam.

[0062] In this embodiment, the cross-section of the second insulating pad 15 is L-shaped, and the vertical plate of the second insulating pad 15 extends into a rectangular frame in the z direction. The second insulating pad 15 protects the battery components 2 on both sides of the battery pack to ensure that the outer shell 21 of the battery components 2 on both sides does not contact the support frame 11. In specific manufacturing, the second insulating pad 15 can be made of PP board, ABS board or electrical board, etc.

[0063] In this embodiment, the first insulating pad 12 is installed at both ends of each battery component 2. It mainly consists of a vertical plate located inside the first side beam and a plug plate 122 folded over the top of the first side beam. The plug plate 122 has a plug groove 124 for inserting battery component mounting ears. During installation, the pressure plate 13 fixes the plug plate of the first insulating pad 12 onto the support frame 11 and applies a binding force to the battery component 2 in the z direction.

[0064] The number of each first insulating pad 12 can be adapted to different numbers of battery components 2. That is, the two ends of a single battery component can be respectively equipped with a first insulating pad 12, or multiple battery components 2 can share a set of first insulating pads 12. If each battery component 2 is equipped with a first insulating pad 12, the installation accuracy requirement for each battery component 2 is smaller, which can reduce the installation difficulty and installation deviation of the battery components 2. If multiple battery components 2 share a set of first insulating pads 12, the manufacturing cost of the first insulating pads 12 can be reduced accordingly, while also saving installation time and simplifying the installation steps. In this embodiment, each battery component 2 is provided with a first insulating pad 12 at both ends.

[0065] like Figure 5 and Figure 6 As shown, to further enhance the safety of battery components, the first insulating pad 12 in this embodiment also includes a support plate 121 connected to the bottom of the vertical plate, so that the first insulating pad 12 has a Z-shaped structure. Specifically, the support plate 121, the plug-in plate 122, and the mounting plate 123 can be integrally molded from insulating material, specifically reinforced nylon (PA66 and glass fiber), ensuring insulation while also possessing a certain strength. During manufacturing, the plug-in plate 122 is simultaneously formed with at least one plug-in groove 124, the number of which is consistent with the number of mounting ears 211 on the end plate of the outer casing 21. Figure 1 As shown, there are two mounting ears 211 on one side end plate of the battery component 2, and correspondingly, each plug-in plate 122 has two plug-in slots 124. At the same time, the size of the plug-in slot 124 and the mounting ear 211 must match, or the size of the plug-in slot 124 is slightly larger than the size of the mounting ear 211, so that the mounting ear 211 of the battery component 2 can be inserted into the plug-in slot 124 of the plug-in plate 122.

[0066] After the first insulating pads 12 are respectively fitted onto both ends of the battery components 2, the support plates 121 of the first insulating pads 12 need to extend into support frames 11 in the horizontal direction to ensure that the outer shells 21 of each battery component 2 do not contact the support frames 11, thereby improving insulation reliability and the safety of the battery components 2. Furthermore, as... Figure 5 and Figure 6 As shown, the portion of the support plate 121 extending beyond the support frame 11 is provided with a protruding ridge 125. The thickness of the protruding ridge 125 is greater than the thickness of the support plate 121, increasing the creepage distance between the battery component 2 and the support frame 11. This protruding ridge 125 ensures insulation performance while minimizing the size of the support plate 121 of the first insulating pad 12, thereby reducing manufacturing costs. When the support plate 121 does not have this protruding ridge 125, the portion of the support plate 121 extending beyond the support frame 11 needs to be longer to meet the creepage distance requirements between the battery component 2 and the support frame 11.

[0067] like Figure 5and Figure 6 As shown, in this embodiment, baffles 126 are respectively provided on both sides of the first insulating pad 12, and the end face of each baffle 126 is parallel to the yz plane. After the first insulating pad 12 is fitted onto the end of the battery component 2, the baffles 126 are located between the outer shells of adjacent battery components 2, which can improve the insulation reliability between adjacent battery components 2 when the battery components 2 are closely arranged. At the same time, the baffles 126 can also limit the battery component 2 in the x direction, further improving the installation reliability of the battery component 2.

[0068] like Figure 1 and Figure 8 As shown, the first insulating pad 12 is fitted onto both ends of the battery component 2. Subsequently, the insertion plate 122 of the first insulating pad 12 is placed on the support frame 11 and fixed by the pressure plate 13. In this embodiment, there are two pressure plates 13, extending along the x-direction. The two pressure plates 13 are located at both ends of each battery component 2 and are fixed to the side beams extending along the x-direction of the support frame 11, respectively, to clamp and fix the insertion plate 122 of the first insulating pad 12.

[0069] In its fabrication, the aforementioned pressure plate 13 can be a flat plate structure to facilitate connection with the support frame 11. In this embodiment, as shown... Figure 7 As shown, the pressure plate 13 also has a downward folded edge 131 structure. The folded edge 131 structure can increase the strength of the pressure plate 13 and increase the stability of the connection when it is fixed to the support frame 11. In specific manufacturing, the sheet metal part is bent to form the pressure plate 13.

[0070] To facilitate on-site connection, the connection hole for the pressure plate 13 to connect with the connecting screw is an oblong hole. This oblong hole can extend in either the x-direction or the y-direction; that is, the pressure plate 13 can simultaneously have oblong holes extending in both the x-direction and y-direction. During actual assembly, the oblong hole allows adjustment of the pressure plate 13's installation position in both the x and y directions, compensating for installation errors between the pressure plate 13 and the support frame 11 and ensuring reliable connection.

[0071] Furthermore, in this embodiment, an insulating buffer pad 14 extending in the x-direction is provided between the support frame 11 and the plug-in plates 122 of each first insulating pad 12. The insulating buffer pad 14 not only further improves the insulation performance between the support frame 11 and the battery component 2, but also presses the plug-in plates 122 of each first insulating pad 12 firmly against the top surface of the support frame 11, improving the installation reliability of the first insulating pad 12. This insulating buffer pad 14 can be implemented using silicone pads or the like. In addition, the insulating buffer pad 14 can adjust the height of each battery component in the z-direction, ensuring that the height of each battery component 2 is consistent, facilitating electrical connections, heat transfer pipe connections, and flue gas pipe connections between the battery components 2.

[0072] During installation, two first insulating pads 12 are respectively fitted onto both ends of the battery component 2, and the mounting ears 211 at both ends of the battery component 2 are respectively embedded into the insertion slots 124 of the insertion plate 122. Subsequently, an insulating buffer pad 14 is installed on the support frame 11, and N battery components 2 with first insulating pads 12 are arranged sequentially on the support frame 11. Two pressure plates 13 extending in the x direction are respectively fixedly connected to the side beams extending in the x direction of the support frame 11. At this time, the insertion plate 122 of the first insulating pad 12 is fixedly clamped between the pressure plate 13 and the support frame 11 to fix the battery component 2 on the support frame 11.

[0073] Example 2

[0074] like Figure 8 As shown, this embodiment provides a battery pack, which includes the battery pack mounting platform 1 and multiple battery components 2 as described in Embodiment 1. Figure 8 The diagram schematically shows 10 battery components 2, which are arranged along the x-direction on the support frame 11.

[0075] like Figure 9 and Figure 10 As shown, the battery component 2 in this embodiment includes a housing 21 and multiple individual batteries 22 arranged in the same direction within the housing 21. The individual batteries 22 in this embodiment are prismatic batteries, and their number can be adjusted according to actual needs. The internal cavity of each individual battery 22 includes an electrolyte area and a gas area. After the multiple individual batteries 22 are arranged in the same direction within the housing 21, a clearance hole is provided on the top plate of the housing 21 corresponding to the polarity terminal 221 of each individual battery 22. The polarity terminal 221 of each individual battery 22 extends out of the corresponding clearance hole as the polarity terminal 221 of the battery component 2 (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 21 corresponding to the clearance hole is fixedly sealed to the housing of the individual battery 22.

[0076] It should be noted that the polarity terminal 221 of the single cell 22 here can be the terminal post of the single cell 22. In order to prevent the terminal post of the single cell 22 from not being able to extend smoothly out of the clearance hole as the polarity terminal 221, a terminal post adapter can be connected to the terminal post of the single cell 22, and the overall structure of the terminal post of the single cell 22 and the terminal post adapter can be used as the polarity terminal 221 of the single cell 22.

[0077] The aforementioned outer casing 21 has a shared chamber, the inner cavity of which is connected to the inner cavities of all individual battery cells 22.

[0078] The aforementioned shared chamber can be an electrolyte shared chamber. The inner cavity of the electrolyte shared chamber is connected to the electrolyte area inside all individual battery cells 22. Through the electrolyte shared chamber, each individual battery cell 22 is in a uniform electrolyte environment, ensuring the uniformity of the electrolyte within each individual battery cell 22 and improving the performance and charge-discharge cycle life of the battery component 2. In this embodiment, the electrolyte shared chamber is a liquid channel located between the bottom plate of the outer casing 21 and the bottom of each individual battery cell 22.

[0079] The aforementioned shared chamber can also be a gas-sharing chamber. The inner cavity of the gas-sharing chamber is connected to the gas region of all individual battery cells 22. The gas balance of each individual battery cell 22 is achieved through the gas-sharing chamber, which can also improve the performance of the battery component 2 and its charge-discharge cycle life. In this embodiment, the gas-sharing chamber is a gas channel provided on the top plate of the outer casing 21. At this time, the top plate of the outer casing 21 has a protrusion extending along the arrangement direction of the individual battery cells 22, and a gas channel is formed at the protrusion.

[0080] 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 22. Through a gas-liquid shared chamber, each individual battery cell 22 can be in a unified electrolyte environment and gas environment, which improves the performance of the battery component 2 and its charge-discharge cycle life.

[0081] To vent thermal runaway fumes from the housing 21 of the battery component 2, this embodiment provides a vent on the housing 21 that communicates with the inner cavity of the housing 21; normally, this vent communicates with the shared chamber. The vent on the housing 21 is equipped with a vent pipe assembly that communicates with the shared chamber, and the vent pipe assemblies of adjacent battery components 2 are connected by pipes to form a vent manifold 3. When a single cell 22 in any battery component 2 experiences thermal runaway, the thermal runaway fumes can be discharged through the vent manifold 3, reducing the risk of combustion or explosion of the battery component 2 or battery pack.

[0082] like Figure 10 As shown, to further improve the safety of the battery component 2 during use in this embodiment, a heat transfer pipe 4 is connected to the portion of the polar terminal 221 of each individual battery 22 that extends out of the outer casing 21. The heat transfer pipe 4 exchanges heat with the polar terminal 221 of each individual battery 22. When the temperature of the battery component 2 is higher than a set threshold, the battery component 2 is cooled by introducing a lower temperature heat transfer medium into the heat transfer pipe 4. When the temperature of the battery component 2 is lower than the set threshold, the battery component 2 is heated by introducing a higher temperature heat transfer medium into the heat transfer pipe 4. By controlling the temperature of the heat transfer medium, it can be ensured that the battery component 2 always operates at the normal operating temperature.

[0083] like Figure 10As shown, the top of the outer shell 21 of the battery component 2 has two heat transfer pipes 4. Each heat transfer pipe 4 extends along the y-axis and the two heat transfer pipes 4 are arranged along the x-axis. Each polar terminal 221 of the battery component 2 is provided with a through groove. The two heat transfer pipes 4 are respectively embedded in the through grooves of the polar terminals 221 located on different sides. One heat transfer pipe 4 is embedded in the through groove of the positive polar terminal 221 of the battery component 2, and the other heat transfer pipe 4 is embedded in the through groove of the negative polar terminal 221 of the battery component 2. The heat transfer pipe 4 has a channel for the heat transfer medium to pass through, and heat exchange is performed on the polar terminals 221 of the battery component 2 through the heat transfer pipe 4.

[0084] Simultaneously, in this embodiment, an insulating sealant layer is laid on the top plate of the outer casing 21. The insulating sealant layer encapsulates at least a portion of the structure of the heat transfer tube 4 and the polarity terminal 221, with the top of the heat transfer tube 4 exposed, serving as an electrical connection. During the operation of the battery component 2, internal temperature changes may cause water vapor condensation. The insulating sealant layer isolates external moisture, reduces internal humidity changes, and prevents water droplets from forming on the surfaces of the heat transfer tube 4 and the polarity terminal 221, thus preventing short circuits and component corrosion caused by condensation. Furthermore, encapsulating a portion of the structure of the heat transfer tube 4 and the polarity terminal 221 within the sealant layer makes the connections between components tighter, reducing relative displacement between components under vibration, impact, and other conditions, and enhancing the overall structural stability of the battery component 2.

[0085] Furthermore, because the polarity terminal 221 of the individual battery 22 is directly exposed to the external environment, there is a significant safety hazard during use due to the energized polarity terminal 221. Therefore, if... Figure 8 and Figure 9 As shown, in this embodiment, a protective shell 23 is provided on the outside of the battery component 2 to provide insulation protection for the polarity terminal 221 of the individual battery 22. The protective shell 23 avoids the potential safety hazards of the individual battery 22 polarity terminal 221 being exposed during the operation of the battery component 2, and also avoids the problem of foreign objects from the external environment falling into the position of the individual battery 22 polarity terminal 221 and causing a short circuit in the battery component 2, thereby improving the safety of the battery component 2.

[0086] During the actual assembly of battery component 2, the heat transfer pipe 4 and the explosion venting manifold 3 are both located inside the protective housing 23. The protective housing 23 protects the heat transfer pipe 4 and the explosion venting manifold 3 to improve the safety of the battery pack during use.

[0087] After the battery components 2 are assembled, first insulating pads 12 are fitted onto both ends of each battery component 2. During installation, the mounting ears 211 at both ends of the battery component 2 are inserted into the insertion slots 124 on the insertion plate 122, and the end face of the mounting plate 123 of the first insulating pad 12 is in close contact with the end plate of the battery component 2. Then, the battery components 2 with the first insulating pads 12 are placed in the support frame 11 in sequence, and the insertion plates 122 of the first insulating pads 12 are placed on the support frame 11. Then, a pressure plate 13 is placed above each insertion plate 122, and the pressure plate 13 is fixed to the support frame 11 with bolts. The insertion plates 122 at both ends of each battery component 2 are clamped and fixed between the pressure plate 13 and the support frame 11.

[0088] In addition, such as Figure 11 As shown, in this embodiment, an insulating liner 5 can also be provided between the outer shells 21 of adjacent battery components 2. The insulating liner 5 can not only further ensure the insulation between adjacent battery components, but also has a certain deformation when each battery component is installed, which facilitates the installation of the battery components.

[0089] After installation, the first insulating pad 12 and the second insulating pad 15 achieve insulation between each battery component and the support frame, improving the insulation reliability and safety of the battery components during use. At the same time, the support frame provides binding forces in the y and x directions to the N battery components. The pressure plate fixes the plug plate of the first insulating pad 12 on the first side beam and provides binding forces in the z direction to the N battery components, fixing each battery component on the support frame from multiple angles to ensure that the battery components can work stably and reliably.
