Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage devices, and particularly relates to an energy storage rack and an energy storage container.

Background Art

[0002] In application scenarios such as the power supply of new energy vehicles, distributed power generation storage, and peak shaving of power grids, energy storage containers have advantages such as being able to be quickly integrated and operated. Generally, an energy storage container includes a container body and an energy storage rack integrated with the container body, and a battery pack for storing electrical energy is installed in the energy storage rack. The battery pack has a relatively high temperature requirement during operation. When the temperature of one battery pack exceeds the normal operating temperature due to the ambient temperature or the heat generated by the battery pack itself during charge and discharge, in order to maintain the stable operation of the energy storage container and extend the service life of the battery pack, the battery pack needs to exchange heat.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Currently, energy storage racks are generally equipped with heat exchange pipelines for transporting heat exchange media. The heat exchange medium flows into each battery pack through the heat exchange pipeline to exchange the heat of the battery pack. After heat exchange, the heat exchange medium flows out through the heat exchange pipeline to form a heat exchange cycle. Since the number of battery packs in the energy storage rack is large, the structure of the heat exchange pipeline is complex and occupies a large space. Therefore, the energy density of the energy storage rack and the energy storage container decreases, which does not contribute to the weight reduction and miniaturization of the energy storage rack and the energy storage container. Furthermore, due to the large number of battery packs, the battery packs block and interfere with each other, making the connection and maintenance between the heat exchange pipeline and the battery pack difficult.

[0004] In view of the above-mentioned drawbacks found in the related art, an object of the present invention is to provide an energy storage rack and an energy storage container for solving the problems of the prior art, namely, the complex structure of the heat exchange pipeline occupying a large space and the difficulty in connection and maintenance between the heat exchange pipeline and the battery pack.

Means for Solving the Problems

[0005] To achieve the above, the present invention provides an energy storage rack including a frame. In the frame, a plurality of layers of accommodation spaces stacked in a first direction are provided. The frame includes four vertical beams arranged in the first direction, and the four vertical beams are the first vertical beam, the second vertical beam, the third vertical beam, and the fourth vertical beam. Flow paths are arranged in each of the four vertical beams.

[0006] In a second direction orthogonal to the first direction, the first vertical beam and the second vertical beam are located on one side of the accommodation space, and the third vertical beam and the fourth vertical beam are located on the other side of the accommodation space with respect to the first vertical beam and the second vertical beam.

[0007] Two battery packs are installed in each accommodation space of each layer, and the two battery packs are the first battery pack and the second battery pack respectively. The first battery pack is arranged near the first vertical beam and the second vertical beam, and the second battery pack is arranged near the third vertical beam and the fourth vertical beam.

[0008] The first battery pack has a first inlet for the heat exchange medium to flow in and a first outlet for the heat exchange medium to flow out. The second battery pack has a second inlet for the heat exchange medium to flow in and a second outlet for the heat exchange medium to flow out.

[0009] A heat exchange flow path is installed in each battery pack. The heat exchange flow path of the first battery pack communicates with the first inlet and the first outlet, and the heat exchange flow path of the second battery pack communicates with the second inlet and the second outlet.

The panel of the first battery pack is located on the side surface of the first battery pack close to the first vertical beam and the second vertical beam. The panel of the second battery pack is located on the side surface of the second battery pack close to the third vertical beam and the fourth vertical beam.

[0012] Optionally, each battery pack includes a housing body and a battery assembly. The battery assembly is arranged in the space surrounded by the housing body and the panel, and the panel and the housing body are detachably connected.

[0013] Optionally, a communication port and a charge and discharge port are installed on the panel.

[0014] Optionally, the energy storage rack further includes a plurality of connecting pipes corresponding to the first inlet, the first outlet, the second inlet, and the second outlet.

[0015] Optionally, each connecting pipe is an elastic hose.

[0016] Optionally, a quick connector is installed at each of the first inlet, the first outlet, the second inlet, and the second outlet. Each of the first inlet, the first outlet, the second inlet, and the second outlet communicates with the corresponding connecting pipe through the quick connector.

[0017] Optionally, the frame further includes a connecting member, and the connecting member is connected to the four vertical beams.

[0018] There are a plurality of connecting members, and the connecting members are arranged in sequence in the first direction to form an accommodation space within the frame.

[0019] Optionally, the frame is arranged in the first direction and further includes auxiliary support beams connected to the connecting members.

[0020] Optionally, general communication ports are installed at the ends of each vertical beam corresponding to the vertical beams, and the general communication ports communicate with the flow paths within the vertical beams.

[0021] The present invention further provides an energy storage container including a container body and a plurality of energy storage racks arranged on the container body described in any of the above. The energy storage racks are arranged side by side in a third direction perpendicular to the first direction and the second direction.

[0022] Optionally, the first vertical beam is separated from the second vertical beam in the third direction, and the first battery pack enters and exits the accommodation space through the gap between the first vertical beam and the second vertical beam. The third vertical beam is separated from the fourth vertical beam in the third direction, and the second battery pack enters and exits the accommodation space through the gap between the third vertical beam and the fourth vertical beam.

[0023] Optionally, two adjacent vertical beams that are close to each other between two adjacent energy storage racks are combined into an integrated vertical beam, and the two flow paths of the integrated vertical beam are separated from each other.

[0024] Optionally, a container door is installed on the side surface of the container body in the second direction with respect to the energy storage rack.

[0025] Optionally, a plurality of energy storage racks are arranged side by side in two energy storage assemblies spaced apart from each other in a second direction, and the gap between the two energy storage assemblies is used for an operator to pass through.

Advantages of the Invention

[0026] As described above, the effects obtained by the present invention include the following. Flow paths are installed in each vertical beam, and since the flow paths communicate with the heat exchange flow paths of the corresponding battery packs, the heat exchange medium can flow into the battery packs through the vertical beams and exchange heat with the battery packs, and the heat exchange medium after heat exchange can flow out from the vertical beams. By replacing a part of the heat exchange pipeline with the arrangement of the flow paths in each vertical beam, the structure of the energy storage rack is simplified, the space occupied by the heat exchange pipeline is reduced, and the material cost and installation cost of the pipeline are reduced. It is advantageous for the miniaturization and weight reduction of the energy storage rack, and the energy density of the energy storage rack can be improved. At the same time, the first vertical beam and the second vertical beam are located on one side of the accommodation space, the third vertical beam and the fourth vertical beam are located on the other side of the accommodation space with respect to the first vertical beam and the second vertical beam, the first battery pack is arranged near the first vertical beam and the second vertical beam, and the second battery pack is arranged near the third vertical beam and the fourth vertical beam. That is, the two battery packs are installed close to the corresponding vertical beams. Therefore, when connecting the first battery pack to the first vertical beam and the second vertical beam, or when performing maintenance on the first battery pack, the connection or maintenance can be carried out from the frame side corresponding to the first vertical beam and the second vertical beam. When connecting the second battery pack to the third vertical beam and the fourth vertical beam, or when performing maintenance on the second battery pack, or when performing maintenance on the second battery pack, the connection or maintenance can be carried out from the frame side corresponding to the third vertical beam and the fourth vertical beam, which is simple and convenient. Furthermore, since the two battery packs are close to the corresponding vertical beams, the two battery packs are far apart from each other, the interference between the two battery packs is reduced, and the connection between the battery packs and the vertical beams and the maintenance of the battery packs can also be easily carried out.

Mode for Carrying Out the Invention

[0028] The implementation of the present invention will be described below with reference to specific embodiments. A person skilled in the art can easily understand other advantages and effects of the present invention from the disclosure of this specification.

[0029] Referring to FIGS. 1 to 21, it should be noted that the structures, scales, dimensions, etc. shown in the accompanying drawings of this specification are used solely in conjunction with the content disclosed in this specification so that those skilled in the art can understand and read them, and are not intended to define the conditions for implementing the present invention. Therefore, any structural change, change in proportional relationship, or adjustment of dimensions that can be achieved without affecting the effects and purposes that can be achieved by the present invention shall be within the scope of the technical content disclosed in the present invention. Also, terms such as "upper", "lower", "left", "right", "middle", "one side", etc. cited in this specification are used solely for the convenience of explanation and are not used to limit the scope of application of the present invention. Even when changing or adjusting their relative relationships without substantially changing the technical content, they shall be included in the scope of application of the present invention.

[0030] Referring to FIGS. 1 to 13, the present embodiment provides an energy storage rack 10 including a frame 1 in which accommodation spaces 18 for a plurality of layers stacked in a first direction α are provided. The frame 1 has four vertical beams arranged along the first direction α, and flow paths 111 are arranged in each of the four vertical beams.

[0031] Specifically, the fourth vertical beams are the first vertical beam 11, the second vertical beam 12, the third vertical beam 13, and the fourth vertical beam 14, respectively. In a second direction β, the first vertical beam 11 and the second vertical beam 12 are located on one side of the accommodation space 18, and the third vertical beam 13 and the fourth vertical beam 14 are located on the other side of the accommodation space 18 with respect to the first vertical beam 11 and the second vertical beam 12. The second direction β is orthogonal to the first direction α.

[0032] Two battery packs are installed in each accommodation space, and the two battery packs are the first battery pack 31 and the second battery pack 32. The first battery pack 31 is arranged near the first vertical beam 11 and the second vertical beam 12, and the second battery pack 32 is arranged near the third vertical beam 13 and the fourth vertical beam 14.

[0033] As shown in FIG. 2, heat exchange channels 308 are installed in the first battery pack 31 and the second battery pack 32, respectively. The first battery pack 31 has a first inlet 304 for the heat exchange medium to flow in and a first outlet 305 for the heat exchange medium to flow out, and the heat exchange channel 308 of the first battery pack 31 communicates with the first inlet 304 and the first outlet 305. The second battery pack 32 has a second inlet 306 for the heat exchange medium to flow in and a second outlet 307 for the heat exchange medium to flow out, and the heat exchange channel 308 of the second battery pack 32 communicates with the second inlet 306 and the second outlet 307.

[0034] The first inlet 304 and the first outlet 305 of the first battery pack 31 are installed close to the first vertical beam 11 and the second vertical beam 12, and the second inlet 306 and the second outlet 307 of the second battery pack 32 are arranged near the third vertical beam 13 and the fourth vertical beam 14.

[0035] The first inlet 304 communicates with the flow path 111 of the first vertical beam 11, and the first outlet 305 communicates with the flow path 111 of the second vertical beam 12. The second inlet 306 communicates with the flow path 111 of the third vertical beam 13, and the second outlet 307 communicates with the flow path 111 of the fourth vertical beam 14.

[0036] The heat exchange flow path 308 is used for heat exchange with the inside of the battery pack so that the temperature of the battery pack is maintained within an appropriate temperature range, and the energy storage efficiency, charge and discharge efficiency, and safety performance of the battery pack are maintained.

[0037] In some embodiments, the heat exchange flow path 308 may be disposed within a heat exchange member such as a heat exchange plate. Since the heat exchange member is separately disposed and assembled within the battery pack, assembly and maintenance can be easily performed. However, due to the presence of the heat exchange member, the number of members and components within the battery pack increases, occupying a large amount of space, resulting in an increase in assembly man-hours and a decrease in the space utilization rate within the housing body 302.

[0038] In some other embodiments, the heat exchange flow path 308 may be integrated with the inner wall of the housing body 302 such as the bottom of the battery pack, and there is no need for separate arrangement. In this way, the number of members and components within the battery pack is reduced, the assembly procedure is simplified, the available space within the battery pack is increased, and the energy density of the battery pack is increased. However, since the heat exchange flow path 308 is integrated with the inner wall of the housing body 302, the processing difficulty of the housing body 302 is increased, and it may be difficult to easily replace or maintain the heat exchange flow path 308.

[0039] In some embodiments, two battery packs are installed only in some of the accommodation spaces 18, and no battery pack is installed in the remaining accommodation spaces 18, or only one battery pack is installed. In this embodiment, a first battery pack 31 and a second battery pack 32 are installed in each accommodation space 18. The specific number of battery packs in the energy storage rack 10 may be set according to the energy storage requirements of the energy storage rack 10. When two battery packs are installed in each accommodation space 18, the energy storage rack 10 has the maximum energy storage capacity and energy density.

[0040] A flow path 111 is installed in each vertical beam, and the flow path 111 communicates with the heat exchange flow path 308 of the corresponding battery pack. Therefore, the heat exchange medium can flow into the battery pack through the vertical beam and exchange heat with the battery pack, and the heat exchange medium after heat exchange can also flow out from the vertical beam. The arrangement of the flow path 111 in each vertical beam replaces a part of the heat exchange pipeline, so that the structure of the energy storage rack 10 is simplified, the space occupied by the heat exchange pipeline is reduced, and the material cost and installation cost of the pipeline are reduced. This contributes to the miniaturization and weight reduction of the energy storage rack 10, and can improve the energy density of the energy storage rack 10.

[0041] The first battery pack 31 is disposed near the first vertical beam 11 and the second vertical beam 12, and the second battery pack 32 is disposed near the third vertical beam 13 and the fourth vertical beam 14. That is, the two battery packs are installed close to the corresponding vertical beams. Therefore, when connecting the first battery pack 31 to the first vertical beam 11 or the second vertical beam 12, or when performing maintenance on the first battery pack 31, the connection and maintenance can be carried out from the side of the frame 1 corresponding to the first vertical beam 11 and the second vertical beam 12. When connecting the second battery pack 32 to the third vertical beam 13 or the fourth vertical beam 14, or when performing maintenance on the second battery pack 32, the connection and maintenance can be carried out from the side of the frame 1 corresponding to the third vertical beam 13 and the fourth vertical beam 14, which is simple and convenient. Furthermore, since the two battery packs are close to the corresponding vertical beams, the two battery packs are far apart from each other, the interference between the two battery packs is reduced, and the connection between the battery pack and the vertical beam and the maintenance of the battery pack can also be easily carried out. In the present embodiment, the vertical beam is made of a profile, and the flow path 111 in the vertical beam can be directly extruded without additional processing during profile extrusion, so the overall cost is reduced.

[0042] In some embodiments, the first outlet 305 is disposed near the first vertical beam 11, the first inlet 304 is disposed near the second vertical beam 12, the second outlet 307 is disposed near the third vertical beam 13, and the second inlet 306 is disposed near the fourth vertical beam 14. In this embodiment, the first outlet 305 is disposed near the second vertical beam 12, the first inlet 304 is disposed near the first vertical beam 11, the second inlet 306 is disposed near the third vertical beam 13, and the second outlet 307 is disposed near the fourth vertical beam 14. The first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307 are close to the connected vertical beams, so the connection and maintenance between the vertical beam and the corresponding battery pack are easy.

[0043] In some embodiments, the first direction α is set to the horizontal direction, that is, the multi-layer accommodation spaces 18 are stacked in order in the horizontal direction. As shown in FIGS. 1, 2, and 4, in this embodiment, the first direction α is set to the vertical direction, the second direction β is set to the horizontal direction, and the multi-layer accommodation spaces 18 are stacked in order in the vertical direction. Thereby, the space in the height direction is utilized to the maximum extent, and the space utilization rate of the energy storage rack 10 is improved. Further, when installing or removing the battery pack, the battery pack can enter the accommodation space 18 in the horizontal direction, which is convenient for the operator.

[0044] Referring to FIGS. 2, 8 to 11, in this embodiment, each battery pack includes a panel 301. The first inlet 304 and the first outlet 305 of the first battery pack 31 are arranged on the panel 301 of the first battery pack 31, and the second inlet 306 and the second outlet 307 of the second battery pack 32 are arranged on the panel 301 of the second battery pack 32. The side where the panel 301 is located is the operating side of each battery pack. The panel 301 of the first battery pack 31 is located on the side surface of the first battery pack 31 close to the first vertical beam 11 and the second vertical beam 12, and the panel 301 of the second battery pack 32 is located on the side surface of the second battery pack 32 close to the third vertical beam 13 and the fourth vertical beam 14. Operations such as connection and maintenance of the panel 301 of the first battery pack 31 can be performed from the positions of the first vertical beam 11 and the second vertical beam 12. Also, operations such as connection and maintenance of the panel 301 of the second battery pack 32 can be performed from the positions of the third vertical beam 13 and the fourth vertical beam 14. Therefore, these operations can be easily executed.

[0045] In this embodiment, each battery pack includes a charge and discharge port 309 and a communication port 310. As shown in FIG. 11, the charge and discharge port 309 and the communication port 310 are also arranged on the panel 301. Specifically, the charge and discharge port 309 is a high-voltage port including a charge port and a discharge port. The charge port is used to charge the battery pack, and the discharge port is used to output electrical energy from the battery pack. The communication port 310 is a low-voltage port, and communication information, sensor detection results, and low-voltage power are all output via the communication port 310. In this embodiment, the explosion-proof valve 311 of the battery pack is also arranged on the panel 301. The explosion-proof valve 311 can release the pressure of the battery pack when the pressure of the battery pack exceeds the safety threshold, prevent the explosion of the battery pack, and improve the safety performance of the battery pack.

[0046] As shown in FIG. 10, in this embodiment, each battery pack includes a housing body 302 and a battery assembly. The panel 301 and the housing body 302 are detachably connected, and the battery assembly is arranged in the internal space surrounded by the housing body 302 and the panel 301. The battery assembly is used to store electrical energy, and the housing body 302 and the panel 301 are used to fix, support, and protect the battery assembly. Since the panel 301 and the housing body 302 are arranged separately and detachably connected, the maintenance and replacement of the panel 301 can be easily performed.

[0047] Specifically, in this embodiment, the housing body 302 has an attachment opening through which the battery assembly can enter and exit the housing body 302, and the panel 301 is detachably connected to the attachment opening. When the panel 301 is connected to the installation opening, the housing body 302 and the panel 301 are combined to form a complete housing body. When the panel 301 is removed, the battery assembly can enter and exit the housing body 302 through the attachment opening, facilitating the maintenance and replacement of the battery assembly.

[0048] As shown in FIGS. 2, 8, and 9, the energy storage rack 10 further includes a plurality of connecting pipes 17. The first inlet 304 communicates with the flow path 111 of the first vertical beam 11 via the corresponding connecting pipe 17, the first outlet 305 communicates with the flow path 111 of the second vertical beam 12 via the corresponding connecting pipe 17, the second inlet 306 communicates with the flow path 111 of the third vertical beam 13 via the corresponding connecting pipe 17, and the second outlet 307 communicates with the flow path 111 of the fourth vertical beam 14 via the corresponding connecting pipe 17. The first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307 may be connected to the corresponding vertical beams via the corresponding connecting pipes 17, thereby reducing the relative position requirements between the battery pack and the vertical beam compared to a direct connection between the battery pack and the vertical beam, and reducing the difficulty of processing and installation. Further, the corresponding gentle increase in the distance between the battery pack and the vertical beam contributes to an increase in the operating space when the battery pack is connected to the vertical beam.

[0049] Specifically, each connecting pipe 17 is an elastic hose in this embodiment. The elastic hose can be bent or deformed according to the mounting position, thereby relaxing the requirements for positional accuracy and processing accuracy between the battery pack and the corresponding vertical beam, and facilitating the connection between the vertical beam and the battery pack.

[0050] In this embodiment, quick connectors are installed at the first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307, respectively. Each of the first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 306 communicates with the corresponding connecting pipe 17 via the quick connector.

[0051] In this embodiment, quick connectors that communicate with the flow path 111 inside the vertical beam are also installed on each vertical beam, and the connecting pipe 17 communicates with the flow path 111 of the vertical beam via the quick connector.

[0052] In practice, one end of each connecting pipe 17 may be pre-connected to the corresponding vertical beam. When the battery pack is attached to the accommodation chamber, the other end of the connecting pipe 17 is connected to the quick connector of the battery pack, so that the heat exchange flow path 308 in the battery pack can communicate with the corresponding flow path 111 in the vertical beam, which is convenient and fast.

[0053] As shown in FIGS. 6 and 7, in the present embodiment, the frame further includes a connecting member 16, and the connecting member 16 is connected to four vertical beams. There are a plurality of connecting members 16, and the plurality of connecting members 16 are arranged in order along the first direction α, forming an accommodation space 18 within the frame.

[0054] The connecting member 16 may be in the form of a plate or a shelf, and the connecting member 16 divides the space within the frame into a plurality of accommodation spaces 18. In the present embodiment, the connecting member 16 includes two opposing support cross beams 19. One support cross beam 19 is connected to the first vertical beam 11 and the fourth vertical beam 14, and the other support cross beam 19 is connected to the second vertical beam 12 and the third vertical beam 13. When the battery pack is installed in the accommodation space 18, the support cross beam 19 supports the battery pack.

[0055] As shown in FIGS. 3 and 12, in the present embodiment, the frame is arranged in the first direction α and further includes an auxiliary support beam 15 connected to the connecting member 16. The auxiliary support beam 15 can enhance the structural strength of the frame in the first direction α so that the frame can support more battery packs in the first direction α. In some embodiments, the frame may also include other reinforcing beams to enhance the structural strength of the frame and avoid deformation of the frame.

[0056] Figure 9 and Figure 13As shown, in this embodiment, in the vertical beam, corresponding to the end of each vertical beam, a general communication port 102 is installed, and the general communication port 102 communicates with the flow path in the vertical beam. The general communication port 102 is configured to communicate with a medium input pipeline or a medium output pipeline. The heat exchange medium flows into the flow path of the vertical beam through the general communication port 102, and then can flow into each battery pack through the flow path for heat exchange. The heat exchange medium after heat exchange flows out from each battery pack, flows into the flow path of another vertical beam, and is discharged from the overall communication port 102 of the vertical beam. Since the general communication port 102 is installed corresponding to the end of the vertical beam while avoiding the battery pack, it is easy to connect with the medium input pipeline and the medium output pipeline.

[0057] As shown in FIGS. 14 to 21, the present invention further provides an energy storage container including a container body 20 and a plurality of the above-described energy storage racks 10 disposed in the container body 20. The energy storage racks 10 are arranged side by side in a third direction γ orthogonal to the first direction α and the second direction β.

[0058] In this embodiment, the direction in which the plurality of energy storage racks 10 are arranged side by side is orthogonal to the direction in which two battery packs in the energy storage rack 10 are connected. The battery pack is inspected from the second direction β, each energy storage rack 10 is arranged in the third direction γ, and all the panels 301 of the battery pack are exposed. Since the adjacent energy storage racks 10 do not obstruct the maintenance path of the battery pack, the maintenance of the battery pack can be easily performed.

[0059] In this embodiment, the first vertical beam 11 is separated from the second vertical beam 12 in the third direction γ, and the first battery pack 31 enters and exits the accommodation space 18 through the gap between the first vertical beam 11 and the second vertical beam 12. The third vertical beam 13 is separated from the fourth vertical beam 14 in the third direction γ, and the second battery pack 32 enters and exits the accommodation space 18 through the gap between the third vertical beam 13 and the fourth vertical beam 14. Since a plurality of energy storage racks 10 are arranged side by side in the second direction β, adjacent energy storage racks 10 do not obstruct the attachment and detachment path of the battery pack, and the battery pack can be easily attached and detached.

[0060] As shown in FIG. 16, in this embodiment, two vertical beams adjacent to each other between two adjacent energy storage racks 10 are coupled to an integrated vertical beam 101, and two flow paths 111 in the integrated vertical beam 101 are separated from each other. The two flow paths 111 in the integrated vertical beam 101 can be obtained simultaneously during extrusion and molding without additional arrangement, so that the structure of the frame is simplified and the material cost of the frame is also reduced.

[0061] A container door 21 is installed on the side surface of the container body 20 in the second direction β with respect to the energy storage rack 10. The container door 21 opens on the side surface of the container body 20 in the second direction β. In this way, after the container door 21 is opened, the panel 301 of the battery pack, that is, the connection position between the battery pack and the corresponding vertical beam, is exposed in the container door 21, and the operator can operate the battery pack through the container door 21.

[0062] In this embodiment, two opposing container doors 21 corresponding to the same energy storage rack 10 are installed on the container body 20, and the two container doors 21 are installed corresponding to both sides of the energy storage rack 10 in the second direction β. When there are multiple energy storage racks 10, the number of container doors 21 increases accordingly. Specifically, in this embodiment, there are four energy storage racks 10 and eight container doors 21. The eight container doors 21 are arranged on both sides of the container body 20.

[0063] As shown in FIGS. 19 to 21, the energy storage rack 10 is arranged with two energy storage assemblies 100 spaced apart from each other in the second direction β, and the gap between the two energy storage assemblies 100 is a passage 201 through which an operator can pass. The operator can connect or inspect the panel 301 of the battery pack located outside the two energy storage assemblies 100 through the container door 21 outside the container body 20. In addition, the operator can also perform connection work and maintenance work through the panel 301 of the battery pack located on both sides of the passage 201. In this way, all battery packs can be connected or inspected without further removing the frame or the container body 20, which is simple and convenient.

[0064] In consideration of the above, in the energy storage rack and the energy storage container provided by the embodiment, a flow path 111 is installed in each vertical beam, and the flow path 111 communicates with the heat exchange flow path of the corresponding battery pack. Therefore, the heat exchange medium can flow into the battery pack through the vertical beam and exchange heat with the battery pack, and the heat exchange medium after heat exchange can flow out of the vertical beam. By replacing a part of the heat exchange pipeline with the arrangement of the flow path 111 in each vertical beam, the structure of the energy storage rack 10 is simplified, the space occupied by the heat exchange pipeline is reduced, and the material cost and installation cost of the pipeline are reduced. This is advantageous for the miniaturization and weight reduction of the energy storage rack 10, and can improve the energy density of the energy storage rack 10.

[0065] At the same time, the first vertical beam 11 and the second vertical beam 12 are located on one side of the accommodation space 18, and the third vertical beam 13 and the fourth vertical beam 14 are located on the other side of the accommodation space 18 with respect to the first vertical beam 11 and the second vertical beam 12. The first battery pack 31 is disposed near the first vertical beam 11 and the second vertical beam 12, and the second battery pack 32 is disposed near the third vertical beam 13 and the fourth vertical beam 14. That is, all four vertical beams are installed outside the frame, and the two battery packs are located near the corresponding vertical beams. When connecting the vertical beams and the battery packs or performing maintenance on the battery packs, the connection and maintenance can be carried out from the frame side where the vertical beams close to the battery packs are located, which is simple and convenient. Furthermore, since the two battery packs are close to the corresponding vertical beams, the two battery packs are far apart from each other, the interference between the two battery packs is reduced, and the connection between the battery packs and the vertical beams and the maintenance of the battery packs can also be easily performed.

[0066] The above-described embodiments illustrate the principles and effects of the present invention and do not limit the present invention. Those skilled in the art can modify or change the above-described embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical idea disclosed in the present invention shall still be included in the scope of the claims of the present invention.
