Description

[Technical field]

[0001] The present invention relates to the technical field of energy storage devices, and in particular to energy storage racks and energy storage containers. [Background technology]

[0002] In application scenarios such as power supply for new energy vehicles, distributed generation storage, and peak shaving for power grids, the energy storage container has the advantage of being able to be quickly integrated and put into operation. In general, the energy storage container includes a container body and an energy storage rack integrated into the container body, and a battery pack for storing electric energy is installed in the energy storage rack. There is a higher temperature requirement during operation of the battery pack. 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 charging and discharging, the battery pack needs to exchange heat in order to maintain the stable operation of the energy storage container and extend the service life of the battery pack. Summary of the Invention [Problem to be solved by the invention]

[0003] At present, energy storage racks are generally equipped with heat exchange ducts for transporting heat exchange medium. The heat exchange medium flows into each battery pack through the heat exchange ducts to exchange heat of the battery packs. After heat exchange, the heat exchange medium flows out through the heat exchange ducts to form a heat exchange cycle. Due to the large number of battery packs in the energy storage rack, the structure of the heat exchange ducts is complicated and occupies a large space. Therefore, the energy density of the energy storage rack and the energy storage container is reduced, which does not contribute to the lightening and miniaturization of the energy storage rack and the energy storage container. In addition, due to the large number of battery packs, the battery packs are blocked and interfere with each other, which makes the connection and maintenance between the heat exchange ducts and the battery packs difficult.

[0004] In consideration of the above-mentioned shortcomings of the related art, the present invention aims to provide an energy storage rack and an energy storage container to solve the problems of the prior art, that is, the structure of the heat exchange pipe is complicated and occupies a large space, and the connection and maintenance between the heat exchange pipe and the battery pack are difficult.

When the second battery pack is connected to the third vertical beam and the fourth vertical beam, or when the second battery pack is maintained, or when the second battery pack is maintained, the connection or maintenance can be performed 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 away 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 be easily performed.

A change or adjustment of the relative relationship without substantially changing the technical content is also included in the scope of application of the present invention.

[0030] 1 to 13, the present embodiment provides an energy storage rack 10 including a frame 1 in which a plurality of layers of storage spaces 18 are installed, stacked in a first direction α. ​​The frame 1 has four vertical beams arranged along the first direction α, and a flow path 111 is 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. In the second direction β, the first vertical beam 11 and the second vertical beam 12 are located on one side of the accommodating space 18, and the third vertical beam 13 and the fourth vertical beam 14 are located on the other side of the accommodating space 18 with respect to the first vertical beam 11 and the second vertical beam 12. The second direction β is perpendicular to the first direction α.

[0032] Two battery packs are installed in each storage space, the two battery packs being a first battery pack 31 and a second battery pack 32. 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.

[0033] 2, the first battery pack 31 and the second battery pack 32 are each provided with a heat exchange passage 308. The first battery pack 31 has a first inlet 304 through which the heat exchange medium flows in and a first outlet 305 through which the heat exchange medium flows out, and the heat exchange passage 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 through which the heat exchange medium flows in and a second outlet 307 through which the heat exchange medium flows out, and the heat exchange passage 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 located 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 positioned near the third vertical beam 13 and the fourth vertical beam 14.

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

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

[0037] In some embodiments, the heat exchange passage 308 may be disposed in a heat exchange member such as a heat exchange plate, and the heat exchange member is disposed and assembled separately in the battery pack, so that assembly and maintenance can be easily performed. However, the presence of the heat exchange member increases the number of members and parts in the battery pack and occupies a large space, so that the number of assembly steps increases and the space utilization rate in the housing body 302 decreases.

[0038] In some other embodiments, the heat exchange passage 308 may be integrated into the inner wall of the housing body 302, such as the bottom of the battery pack, and does not need to be separately located. In this way, the number of components and parts in the battery pack is reduced, the assembly procedure is simplified, the available space in the battery pack is increased, and the energy density of the battery pack is increased. However, since the heat exchange passage 308 is integrated into the inner wall of the housing body 302, the processing of the housing body 302 becomes more difficult, and replacement or maintenance of the heat exchange passage 308 may not be easily performed.

[0039] In some embodiments, two battery packs are installed in only some of the accommodation spaces 18, and no battery packs or only one battery pack is installed in the remaining accommodation spaces 18. 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] Each vertical beam is provided with a flow passage 111, which communicates with the heat exchange flow passage 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 passages 111 in each vertical beam replaces a part of the heat exchange duct, thereby simplifying the structure of the energy storage rack 10, reducing the space occupied by the heat exchange duct, and reducing the material cost and installation cost of the duct. 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 the first battery pack 31 is connected to the first vertical beam 11 or the second vertical beam 12, or when the first battery pack 31 is maintained, the connection or maintenance can be performed from the frame 1 side corresponding to the first vertical beam 11 and the second vertical beam 12. When the second battery pack 32 is connected to the third vertical beam 13 or the fourth vertical beam 14, or when the second battery pack 32 is maintained, the connection or maintenance can be performed from the frame 1 side corresponding to the third vertical beam 13 and the fourth vertical beam 14, which is simple and convenient. In addition, since the two battery packs are close to the corresponding vertical beams, the two battery packs are far away 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 are also easy. In this embodiment, the vertical beams are made of profiles, and the channels 111 in the vertical beams can be directly extruded without additional processing during the profile extrusion, so that the overall cost is low.

[0042] In some embodiments, the first outlet 305 is located near the first vertical beam 11, the first inlet 304 is located near the second vertical beam 12, the second outlet 307 is located near the third vertical beam 13, and the second inlet 306 is located near the fourth vertical beam 14. In this embodiment, the first outlet 305 is located near the second vertical beam 12, the first inlet 304 is located near the first vertical beam 11, the second inlet 306 is located near the third vertical beam 13, and the second outlet 307 is located near the fourth vertical beam 14. Since the first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307 are located near the connected vertical beams, it is easy to connect and maintain the vertical beams and the corresponding battery packs.

[0043] In some embodiments, the first direction α is set to a horizontal direction, that is, the multi-layered accommodating space 18 is stacked in sequence in a horizontal direction. As shown in Figures 1, 2 and 4, in this embodiment, the first direction α is set to a vertical direction, the second direction β is a horizontal direction, and the multi-layered accommodating space 18 is stacked in sequence in a vertical direction, thereby maximizing the use of the space in the height direction and improving the space utilization rate of the energy storage rack 10. In addition, when installing or removing the battery pack, the battery pack can enter the accommodating space 18 in a horizontal direction, which is convenient for the operator.

[0044] 2, 8 to 11, in this embodiment, each battery pack includes a panel 301, and the first inlet 304 and the first outlet 305 of the first battery pack 31 are disposed 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 disposed on the panel 301 of the second battery pack 32. The side on which the panel 301 is disposed is the operating side of each battery pack. The panel 301 of the first battery pack 31 is disposed on a side 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 disposed on a side of the second battery pack 32 close to the third vertical beam 13 and the fourth vertical beam 14. Operations such as connecting and maintaining 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, and operations such as connecting and maintaining 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, so these operations can be performed easily.

[0045] In this embodiment, each battery pack includes a charging / discharging port 309 and a communication port 310. As shown in FIG. 11, the charging / discharging port 309 and the communication port 310 are also arranged on the panel 301. Specifically, the charging / discharging port 309 is a high-voltage port including a charging port and a discharging port. The charging port is used to charge the battery pack, and the discharging port is used to output electric energy from the battery pack. The communication port 310 is a low-voltage port, and the communication information, the sensor detection result, and the low-voltage power supply are all output through 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 a safety threshold, prevent the explosion of the battery pack, and improve the safety performance of the battery pack.

[0046] 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 disposed in an internal space surrounded by the housing body 302 and the panel 301. The battery assembly is used to store electric 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 disposed separately and detachably connected to each other, maintenance and replacement of the panel 301 can be easily performed.

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

[0048] As shown in Figures 2, 8 and 9, the energy storage rack 10 further includes a plurality of connecting pipes 17. The first inlet 304 communicates with the passage 111 of the first vertical beam 11 through the corresponding connecting pipe 17, the first outlet 305 communicates with the passage 111 of the second vertical beam 12 through the corresponding connecting pipe 17, the second inlet 306 communicates with the passage 111 of the third vertical beam 13 through the corresponding connecting pipe 17, and the second outlet 307 communicates with the passage 111 of the fourth vertical beam 14 through 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 through the corresponding connecting pipes 17, which reduces the relative position requirement between the battery packs and the vertical beams and reduces the difficulty of processing and installation compared with the direct connection between the battery packs and the vertical beams. Additionally, the corresponding gradual increase in the distance between the battery pack and the vertical beam contributes to an increase in 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, which can be bent or deformed according to the installation 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, a quick connector is provided at each of the first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307. Each of the first inlet 304, the first outlet 305, the second inlet 306, and the second outlet 307 is connected to a corresponding connecting pipe 17 via the quick connector.

[0051] In this embodiment, each vertical beam is also provided with a quick connector that communicates with the flow passage 111 in the vertical beam, and the connecting pipe 17 communicates with the flow passage 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, and the other end of the connecting pipe 17 is connected to the quick connector of the battery pack when the battery pack is installed in the receiving chamber, so that the heat exchange passage 308 in the battery pack can communicate with the corresponding passage 111 in the vertical beam, which is convenient and fast.

[0053] 6 and 7, in this embodiment, the frame further includes a connecting member 16, which is connected to the four vertical beams. There are a plurality of connecting members 16, which are arranged in sequence along the first direction α to form an accommodation space 18 within the frame.

[0054] The connecting members 16 may be in the form of plates or shelves, and the connecting members 16 divide the space within the frame into a plurality of storage spaces 18. In this embodiment, the connecting members 16 include 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 storage space 18, the support cross beams 19 support the battery pack.

[0055] 3 and 12, in this embodiment, the frame further includes an auxiliary support beam 15 disposed in the first direction α and connected to the connection member 16. The auxiliary support beam 15 can increase 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 increase the structural strength of the frame and avoid deformation of the frame.

[0056] Figure 9 and Figure 13As shown in FIG. 1, in this embodiment, the vertical beams are provided with general communication ports 102 corresponding to the ends of the vertical beams, and the general communication ports 102 communicate with the flow paths in the vertical beams. The general communication ports 102 are configured to communicate with a medium input pipeline or a medium output pipeline. The heat exchange medium can flow into the flow path of the vertical beams through the general communication ports 102, and then flow into each battery pack through a flow path for heat exchange. The heat exchange medium after heat exchange flows out of each battery pack, flows into the flow path of the other vertical beams, and is discharged from the overall communication port 102 of the vertical beams. The general communication ports 102 are installed corresponding to the ends of the vertical beams while avoiding the battery packs, so that it is easy to connect to the medium input pipeline or the medium output pipeline.

[0057] 14 to 21, the present invention further provides an energy storage container including a container body 20 and a plurality of the above-mentioned 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 perpendicular to the first direction α and the second direction β.

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

[0060] 16, in this embodiment, two vertical beams close to each other between two adjacent energy storage racks 10 are combined into an integrated vertical beam 101, and two channels 111 in the integrated vertical beam 101 are separated from each other. The two channels 111 in the integrated vertical beam 101 can be obtained simultaneously during extrusion and molding without additional arrangement, which simplifies the structure of the frame and also reduces the material cost of the frame.

[0061] A container door 21 is installed on the side of the container body 20 in the second direction β relative to the energy storage rack 10. The container door 21 opens on the side 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, i.e., the connection position between the battery pack and the corresponding vertical beam, is exposed in the container door 21, and an operator can operate the battery pack through the container door 21.

[0062] In this embodiment, the container body 20 is provided with two opposing container doors 21 corresponding to the same energy storage rack 10, and the two container doors 21 are provided 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 is increased 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 installed next to 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 an aisle 201 through which an operator passes. The operator can connect or inspect the battery pack panels 301 located outside the two energy storage assemblies 100 through the container door 21 outside the container body 20. The operator can also perform connection work or maintenance work through the battery pack panels 301 located on both sides of the aisle 201. In this way, all the battery packs can be connected or inspected without further removing the frame or the container body 20, which is simple and convenient.

[0064] In view of the above, in the energy storage rack and energy storage container provided by the embodiment, each vertical beam is provided with a flow path 111, and the flow path 111 communicates with the heat exchange flow path of the corresponding battery pack, so that 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 from the vertical beam. The arrangement of the flow path 111 in each vertical beam replaces a part of the heat exchange pipe, so that the structure of the energy storage rack 10 is simplified, the space occupied by the heat exchange pipe is reduced, and the material cost and installation cost of the pipe are reduced. This is favorable for the miniaturization and weight reduction of the energy storage rack 10, and the energy density of the energy storage rack 10 can be improved.

[0065] At the same time, the first vertical beam 11 and the second vertical beam 12 are located on one side of the receiving space 18, and the third vertical beam 13 and the fourth vertical beam 14 are located on the other side of the receiving space 18 relative 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 maintaining the battery packs, the connection and maintenance can be performed from the frame side where the vertical beams close to the battery packs are located, which is simple and convenient. In addition, since the two battery packs are close to the corresponding vertical beams, the two battery packs are far away 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 be easily performed.

[0066] The above-described embodiments are illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Those skilled in the art may 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 ideas disclosed in the present invention are also intended to be included in the scope of the claims of the present invention.
