Description

Technical Field

[0001] This invention 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 invention provides a battery pack mounting platform and a battery pack. Based on the battery pack mounting platform, battery components can be reliably fixed on a support frame, and the structural stability of the battery pack can be improved by optimizing the support frame structure.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0006] This invention provides a battery pack mounting platform. 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. Mounting plates are respectively provided at both ends of the housing, where N is an integer greater than 1. The mounting platform includes a support frame and a fixing assembly. The support frame supports the N battery components and provides binding forces in the x and y directions to the N battery components. The fixing assembly includes at least two pressure plates, each extending along the x-direction and fixedly connected to a side beam extending along the x-direction of the support frame. The mounting plates at both ends of the battery components are clamped between the pressure plates and the support frame. The pressure plates provide binding forces in the z-direction to the N battery components through the mounting plates to fix the battery components to the support frame.

[0007] Furthermore, the fixing assembly also includes 2N protective blocks made of insulating material, each protective block having a mounting groove. The size of the mounting groove is consistent with the outer dimensions of the battery component mounting plate, which is used to embed the battery component mounting plate into the mounting groove of the protective block. The protective block is clamped between the pressure plate and the support frame, so that the battery component is kept insulated from the support frame.

[0008] Furthermore, the pressure plate is formed by bending sheet metal parts.

[0009] Furthermore, the mounting holes on the pressure plate are oblong holes.

[0010] Furthermore, the support frame is a rectangular frame, mainly composed of two first side beams and two second side beams connected together. The first side beams extend along the x-direction and are made of angle steel and U-shaped steel. Rollers are installed inside the U-shaped steel. The second side beams extend along the y-direction and are made of angle steel.

[0011] Furthermore, it also includes an insulating pad embedded in a rectangular frame, the insulating pad having an L-shaped cross-section, the vertical plate of the insulating pad extending out of the rectangular frame in the z-direction, and the horizontal plate of the insulating pad extending out of the rectangular frame in the horizontal direction.

[0012] The present invention also provides a battery pack, which includes N battery components and a battery pack mounting platform; each battery component includes a housing and a plurality of individual batteries arranged in the same direction within the housing; mounting plates are respectively provided on the two end plates of the housing, and each end plate is parallel to the xz plane; the N battery components are arranged sequentially on a support frame along the x direction, the support frame supports the N battery components and provides binding forces in the x and y directions to the N battery components; each pressure plate is fixedly connected to a side beam extending along the x direction of the support frame, and the mounting plates at both ends of the battery components are clamped between the pressure plates and the support frame, and the pressure plates provide binding forces in the z direction to the N battery components through the mounting plates to fix the battery components on the support frame.

[0013] Furthermore, the mounting plates on the same side of the N battery components are clamped between the support frame and the same pressure plate, and the N battery components are fixed and installed by the two pressure plates.

[0014] 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.

[0015] 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.

[0016] Compared with the prior art, the advantages of the technical solution of the present invention are as follows:

[0017] 1. The battery pack installation platform of this invention can reliably install each battery component. After N battery components are placed on a support frame, the support frame provides binding forces to the battery components in the x and y directions, thereby limiting the position of the battery components. Simultaneously, each battery component has mounting plates at both ends of its outer shell. These mounting plates are clamped between a pressure plate and the support frame, and the pressure plate is fixed to the side beam of the support frame. This pressure plate provides binding forces to the battery components in the z direction, further limiting the position of the battery components. During the use of the battery components, this installation platform fixes and installs each battery component on the support frame from multiple angles, achieving the installation and fixation of each battery component to ensure stable and reliable operation.

[0018] Especially when this installation platform is used in mobile charging vehicles, it provides restraint forces to the battery components in multiple directions (x, y, and z) during movement, ensuring the components remain in a relatively stable position and preventing movement or tilting, thus enabling stable operation. Particularly in complex road conditions, the platform provides continuous and stable support and reliable installation for the battery components, protecting their internal structure and connections, preventing shaking and vibration, and guaranteeing normal operation.

[0019] In addition, this type of battery pack installation platform only requires fixing the pressure plates when installing each battery component, saving installation time and simplifying the installation steps.

[0020] 2. In the battery pack installation platform of the present invention, the fixing component further includes multiple protective blocks made of insulating material. Each protective block protects the mounting plate of the battery component, improving the reliability of the mounting plate and avoiding unreliable installation of the battery component due to detachment of the mounting plate. Simultaneously, the protective blocks also ensure the insulation performance of the battery component during use, improving its operational reliability.

[0021] 3. In the battery pack installation platform of the present invention, the pressure plate is formed by bending sheet metal parts. When the installation plate formed by bending the sheet metal parts is clamped and fixed, the bending strength of the pressure plate can be increased, and the stability of the connection can be increased when it is fixed on the support frame.

[0022] 4. In the battery pack installation platform of the present invention, the mounting holes on the pressure plate are oblong holes. During actual assembly, the oblong holes can adjust the relative position of the pressure plate and the support frame in the x or y direction to compensate for the installation error between the pressure plate and the support frame and ensure the reliability of the connection.

[0023] 5. In the battery pack installation platform of the present invention, an insulating pad is provided inside the support frame. The insulating pad is placed between each battery component and the support frame. When the outer shell of the battery component is energized, the insulation performance between the support frame and the battery component is ensured. At the same time, the vertical and horizontal plates of the insulating pad extend out of the support frame to ensure that the outer shell of each battery component does not contact the support frame, thereby improving the insulation reliability and the safety of the battery component.

[0024] 6. In the battery pack installation platform of this invention, the support frame is a rectangular frame, mainly composed of two first side beams and two second side beams connected together. Compared with other support structures, the rectangular frame support structure is relatively stable and easier to manufacture. Meanwhile, the first side beams are formed by a combination of angle steel and U-shaped steel, which can increase the stability and support strength of the support frame. Furthermore, this invention also provides rollers at the bottom of the two first side beams to facilitate the installation and disassembly of the battery pack.

[0025] 7. In the battery pack of the present invention, the battery component places multiple individual cells inside a housing with a shared chamber. The shared chamber is connected to the inner cavity of each individual cell located inside the housing, which reduces the differences between individual cells and improves the consistency between individual cells to a certain extent, thereby improving the cycle life of the battery component to a certain extent.

[0026] 8. In the battery pack of the present invention, 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.

[0027] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

Detailed Implementation

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

In the description of this specification, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0043] 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 via 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 invention according to the specific circumstances.

[0044] Furthermore, in the description of this invention, 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 invention 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 invention.

[0045] This invention provides a battery pack mounting platform for supporting and fixing multiple battery components constituting a battery pack. The battery components can be existing battery packs or modules, or high-capacity batteries. The battery packs or modules can consist of a casing and multiple individual cells connected in parallel or series within the casing (this is a conventional design, where the electrolytes of the individual cells are not shared). The high-capacity batteries described here are batteries composed of multiple individual cells 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.

[0046] 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.

[0047] 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, each battery component requires a separate bracket assembly for installation, and each battery component is fixed to the support frame via the bracket assembly. During installation, the battery component is first stably fixed to the support frame using L-shaped brackets fixed to both ends of the support component, and then the bracket assembly is fixed to the support frame. The installation process for the battery component is relatively complex. Furthermore, when installing each bracket assembly with the battery component, the structure of the bracket assembly 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.

[0048] Based on this, this embodiment provides a battery pack installation platform, which includes a support frame and a fixing assembly; each battery component has a mounting plate on its outer shell. During installation, after placing multiple battery components on the support frame, pressure plates are added to both ends of each battery component. The pressure plates are located above each mounting plate and are fixed to the side beams opposite to the support frame. At this time, the mounting plates at both ends of each battery component are clamped between the pressure plates and the support frame. The pressure plates limit the battery components in the z-direction to fix each battery component on the support frame. This installation method ensures the stability of the battery components on the support frame during battery pack movement, enabling each battery component to work reliably. Especially when this installation platform is applied to mobile charging vehicles, the battery components can maintain a relatively stable position during the movement of the mobile charging vehicle, without moving or tilting, and the battery components can work stably. Particularly in situations with complex road conditions, the installation platform can continuously maintain stable support and reliable installation for the battery components, protecting the internal structure and related connections of the battery components, preventing shaking and bumping, and ensuring the normal operation of the battery components.

[0049] Furthermore, when installing each battery component using the aforementioned mounting platform, there is no need to set up separate bracket assemblies for each battery component; installation can be achieved simply by using a pressure plate. The overall structure of the mounting platform is relatively simple. During installation, the mounting plate of the battery component is simply clamped onto the support frame using the pressure plate to fix it in place. The installation process is simple. After installation, the entire battery pack has a simple and compact structure, high stability, and high energy density.

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment provides a battery pack installation platform for supporting 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.

[0052] like Figure 2 and Figure 3 As shown, the battery pack mounting platform 1 provided in this embodiment includes a support frame 11 and a fixing assembly 12. The support frame 11 supports N battery components 2 in the battery pack. The N battery components 2 are arranged on the support frame 11 along the x-direction. In the x and y directions, the support frame 11 provides binding force to the battery components 2, thereby limiting and fixing the battery components in the x and y directions, where N is an integer greater than 1. To reliably install each battery component 2 onto the support frame 11, mounting plates 211 are respectively provided on the two end plates of the outer shell 21 of the battery component 2. The end plates are parallel to the xz plane, that is, the mounting plates 211 are provided on the end plates of the outer shell 21 that are parallel to the xz plane. The end faces of the mounting plates 211 are parallel to the xy plane. The mounting plates 211 can be integrally manufactured with the end plates of the outer shell 21, or they can be processed separately and then fixed to the end plates of the outer shell 21 by welding or other methods.

[0053] The fixing component 12 in this embodiment includes at least two pressure plates 121. Each pressure plate 121 is located at both ends of the battery component 2 and is fixed to the side beams opposite to the support frame 11. The mounting plates 211 at both ends of each battery component 2 are clamped between the pressure plates 121 and the support frame 11. The pressure plates 121 can provide binding force to the mounting plates 211 in the z direction to fix the battery component 2 in the z direction, thereby achieving stable installation of the battery component 2.

[0054] like Figure 1 and Figure 5 As shown, the battery pack formed by arranging multiple battery components 2 sequentially in a horizontal direction has a cuboid structure. For a battery pack suitable for this shape, such as... Figure 2 and Figure 3 As shown, 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 the two second side beams 112 are arranged at intervals and connected end to end to form a rectangular frame structure. In specific connection, the first side beams 111 and the second side beams 112 can be assembled to form a rectangular frame by welding or screwing.

[0055] 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 component 2. That is, the inner side of the support frame 11 needs to have an inwardly extending support structure so that the battery component 2 can be placed inside the support frame 11. In this embodiment, both the first side beam 111 and the second side beam 112 can be implemented using angle steel. The vertical plate of the angle steel is used to limit the x and y directions of each battery component 2, and the horizontal plate of the angle steel is used to support each battery component 2.

[0056] In some other embodiments, the first side beam 111 and the second side beam 112 may also be made of U-shaped steel, square steel or I-beam steel, etc. When such steel is used, an internal support structure needs to be added, for example, an inner support plate, etc., to support each battery component 2.

[0057] In addition, to facilitate the assembly of the battery pack, such as Figure 4 As shown, this embodiment also includes rollers 113 on the two first side beams 111, which facilitates the movement of the battery pack and the support frame 11. In a specific configuration, the rollers 113 can be positioned on the outer side of the first side beams 111, and a protective cover can be provided on the outer side of the rollers 113 to protect them.

[0058] After the support frame 11 is formed, its inner dimensions are consistent with the dimensions of the battery components 2 after they are arranged. That is, after N battery components 2 are arranged and placed in the support frame 11, the inner dimensions of the support frame 11 in the x and y directions are consistent with the dimensions of the multiple batteries in the x and y directions after they are arranged, so that the support frame 11 limits the multiple battery components 2 in the x and y directions. Accordingly, in this embodiment, fixing components 12 are added on both sides of each battery component 2, and each battery component 2 is fixed in the z direction by the fixing components 12.

[0059] like Figure 2 and Figure 3As shown, the fixing component 12 in this embodiment includes at least two pressure plates 121. The pressure plates 121 are located at both ends of the battery component 2 and are fixed on the side beams opposite to the support frame 11. The mounting plates 211 at both ends of each battery component 2 are clamped between the pressure plates 121 and the support frame 11. At this time, the pressure plates 121 and the support frame 11 limit the mounting plates 211 in the z direction, thereby fixing the battery component 2 in the z direction and finally fixing each battery component 2 on the support frame 11.

[0060] The number of pressure plates 121 is at least two. If the number of pressure plates 121 is more than two, one pressure plate 121 can be used for one or more battery components 2. That is, on the same side of each battery component 2, one pressure plate 121 can clamp and limit the mounting plates 211 of different numbers of battery components 2. For example, on one side of each battery component 2, one pressure plate 121 can clamp and limit the mounting plate 211 of one battery component 2. N battery components 2 require a total of 2N pressure plates to fix them. As another example, one pressure plate 121 can limit the mounting plates 211 of two battery components 2. N battery components 2 require a total of N pressure plates to fix them. If each battery component 2 uses a different pressure plate 121 to clamp the mounting plate 211, this fixing method requires less installation accuracy for each battery component 2, which can reduce the installation difficulty and installation deviation of the battery components 2.

[0061] In this embodiment, the fixing component 12 includes two pressure plates 121, which are located at both ends of each battery component 2 and extend along the x-direction to clamp and limit the mounting plates 211 of the N battery components 2. Using two pressure plates 121 reduces manufacturing costs and facilitates installation and manufacturing. Furthermore, when each end of a battery component 2 uses a pressure plate 121, the pressure plate is fixed to the support frame 11 by multiple connecting screws. Even if one connecting screw loosens, the other screws can still reliably fix the pressure plate 121 to the support frame 11, ensuring reliable installation of the battery components. If 2N pressure plates are needed to fix the N battery components 2, if the connecting screw of one pressure plate 121 loosens or is not properly installed, the battery component 2 may not be reliably limited and fixed in the z-direction, leading to unreliable installation. Using a single pressure plate 121 to install multiple battery components 2 avoids this problem.

[0062] When the pressure plate 121 is specifically manufactured, a flat plate structure can be adopted to facilitate the connection with the support frame 11. In this embodiment, the pressure plate 121 can adopt the following structure: the sheet metal part is bent to form the pressure plate 121. The pressure plate 121 formed by bending the sheet metal part can increase the bending strength of the pressure plate 121 and increase the stability of the connection when clamping and fixing the mounting plate 211.

[0063] In addition, when the first side beam 111 of the support frame 11 is made of angle steel, a connecting plate 114 for connection can be added to the first side beam 111 for easy connection. The connecting plate 114 is provided with mounting holes, and the connecting screws pass through the pressure plate 121 and the connecting plate 114 in sequence to fix the pressure plate 121.

[0064] To facilitate on-site connection, the connection hole for the pressure plate 121 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 121 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 121's installation position in both the x and y directions. When using one pressure plate 121 to install multiple battery components 2, it can compensate for installation errors between the pressure plate 121 and the support frame 11, ensuring reliable connection.

[0065] As described above, the support frame 11 in this embodiment is generally made of structural steel. In actual use, the outer casing 21 of the battery component 2 may be electrified. To ensure the safety of each battery component 2 during use, this embodiment provides an insulating pad 13 inside the support frame 11. The insulating pad 13 is located between each battery component 2 and the support frame 11, achieving insulation between the support frame 11 and the battery component 2. In actual use, the casing of large-capacity batteries is generally electrified; therefore, the insulating pad 13 is mainly suitable for battery packs with large-capacity batteries as battery components.

[0066] like Figure 3 As shown, in specific manufacturing, the shape of the insulating pad 13 is generally consistent with the shape of the support frame 11. Since the support frame 11 is a rectangular frame structure, the insulating pad 13 can also be a rectangular frame structure. During installation, the insulating pad 13 is embedded inside the support frame 11. The cross-section of the insulating pad 13 is L-shaped. At this time, the height of the vertical plate of the insulating pad 13 is higher than the height of the support frame 11, meaning the insulating pad 13 extends into the support frame 11 in the z-direction. The horizontal plates of the insulating pad 13 all extend into rectangular frames in the horizontal direction, ensuring that the outer shell 21 of each battery component 2 does not contact the support frame 11, further improving the insulation reliability of the support frame 11 and the safety of the battery component 2. Specifically, the insulating pad 13 can be made of PP board, ABS board, or electrical board, etc. During installation, the insulating pad 13 is embedded into the support frame 11, followed by the installation of the battery component 2 and the pressure plate 121.

[0067] Furthermore, to further improve the reliability of the battery component 2 during operation, corresponding insulation measures can be taken for the pressure plate 121 in contact with the battery component 2. In this case, the fixing assembly 12 also includes 2N protective blocks 122 made of insulating material. Each protective block 122 has a mounting groove that matches the mounting plate 211 of the battery component 2. The dimension of the mounting groove in the z-direction is consistent with the thickness of the mounting plate of the battery component 2. The mounting plate 211 of the battery component 2 is embedded in the mounting groove of the protective block 122. Specifically, in manufacturing, the vertical plate of the insulating pad 13 inside the support frame 11 extends out of the support frame 11. The mounting plate 211 contacts the insulating pad 13 to achieve corresponding insulation. In this case, the protective block only needs to insulate the portion of the protective block 122 except for the bottom surface. Correspondingly, the cross-section of the protective block 122 can be U-shaped. The mounting plate 211 is embedded in the inner cavity of the U-shaped protective block. The combination of the U-shaped protective block and the insulating pad 13 provides insulation for the mounting plate 211.

[0068] During battery component installation, the protective block 122 is located between the pressure plate 121 and the support frame 11, and the protective block 122 limits the position of the battery component. The protective block 122 has at least the following functions: First, it protects the mounting plate 211 of the battery component 2, preventing the mounting plate 211 of the battery component 2 from separating from the outer shell 21 of the battery component 2 during installation or use when subjected to a large external force, thus avoiding unreliable installation problems caused by the detachment of the mounting plate; Second, it increases the insulation performance between the battery component 2 and the support frame 11, improving the reliability of the battery component during operation.

[0069] Example 2

[0070] This embodiment provides a battery pack installation platform, which is similar in structure to the battery pack installation platform in Embodiment 1, except that the support frame 11 has a different structure.

[0071] like Figure 7 and Figure 8 As shown, in this embodiment of the battery pack installation platform 1, to increase the stability and support strength of the support frame 11, the first side beam 111 and the second side beam 112 can be composed of various types of steel. For example, they can be formed by combining U-shaped steel and angle steel to improve the structural strength of the support frame 11. 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 made of a combination of U-shaped steel and angle steel. When using the combined structure, the angle steel is located on the inside, and the U-shaped steel is set up upside down. The vertical plate of the angle steel is connected to one of the vertical plates of the U-shaped steel. At the same time, a connecting hole for fixing the pressure plate 121 is machined on the top plate of the U-shaped steel. This combination can not only meet the support function of the support frame 11 without adding additional support structural components, but also make the entire support frame 11 have good support strength.

[0072] like Figure 9As shown, to facilitate the assembly of the battery pack, this embodiment also provides rollers 113 at the bottom of the two first side beams 111. The rollers 113 facilitate the movement of the battery pack and the support frame 11. Specifically, the rollers 113 can be installed inside the U-shaped steel section of the first side beam 111, using the space inside the U-shaped steel section as the installation space for the rollers 113. This results in a built-in installation of the rollers 113, eliminating the need for additional space and allowing the battery component 2 to achieve a higher energy density.

[0073] This embodiment can also design the structure of the insulating pad accordingly. In this embodiment, the two ends of the outer shell 21 of the battery component 2 can be provided with insulating devices in the early stage. Therefore, during the later installation, the insulating pad 13 can be provided only in the second side beam 112 of the support frame 11. Therefore, the insulating pad 13 in this embodiment includes two insulating pads 13 provided in the second side beam 112, which is different from the insulating pad of the rectangular frame in Embodiment 1.

[0074] Furthermore, in this embodiment, the protective block 122 completely covers the mounting plate 211 of the battery component 2. That is, the mounting plate 211 can be completely embedded in the mounting groove of the protective block 122. The size of the mounting groove is consistent with the outer dimensions of the battery component mounting plate. The protective block is clamped between the pressure plate and the support frame so that the mounting plate 211 of the battery component 2 does not contact the support frame 11, thereby increasing the insulation reliability.

[0075] Example 3

[0076] like Figure 10 As shown, this embodiment provides a battery pack, which includes a battery pack mounting platform 1 as in Embodiment 1 or Embodiment 2, and multiple battery components 2. The support frame 11 in the battery pack mounting platform 1 is used to support the multiple battery components 2. Figure 10 The diagram schematically shows four battery components 2, which are arranged along the x-direction on the support frame 11.

[0077] like Figure 12As 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] like Figure 12 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.

[0085] like Figure 12 As 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.

[0086] 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.

[0087] 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 10 and Figure 11 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.

[0088] 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.

[0089] like Figure 11 As shown, after the battery components 2 are assembled, they are arranged in sequence in the support frame 11. The protective blocks 122 are installed on the mounting plates 211 of each battery component. Then, pressure plates 121 are placed on both sides of the battery component. The pressure plates 121 are located above each protective block 122 and are fixed to the first side beam of the support frame 11 by connecting screws. The mounting plates 211 at both ends of each battery component 2 are clamped between the pressure plates 121 and the support frame 11. The pressure plates 121 fix the battery components 2 in the z direction to fix each battery component 2 on the support frame 11.

[0090] The mounting plate 211 of each battery component 2 is clamped between the pressure plate 121 and the support frame 11. After the pressure plate 121 and the support frame 11 are connected by bolts, the pressure plate 121 not only fixes the battery component 2 in the z direction, but also applies a certain force to the battery component 2 in the x and y directions. This force can also fix the battery component in the x and y directions.
