[0002] The invention relates to a battery swap station or an energy storage station. Background Art

[0003] In current battery swap stations, battery swap equipment is usually used to transport batteries. Since the battery storage area generates heat when charging the batteries, and the batteries need to be stored at a suitable temperature, the battery storage area needs to be temperature controlled by air conditioning equipment. In the prior art, the temperature of the internal space of the battery swap station is usually adjusted by installing air conditioning equipment. The layout design of the air conditioning installation location, circulation path, and temperature adjustment efficiency is not given, which can easily lead to heat concentration in some internal locations.

[0004] In addition, since the battery swap station includes more fixed equipment, it occupies a large amount of land space, resulting in a waste of land resources. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the battery swap station occupies a large area resulting in waste of land resources, and the temperature regulation efficiency in the battery swap station is low, which easily leads to heat concentration, and to provide a battery swap station or energy storage station.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A battery swap station or energy storage station, comprising a battery swap box and an air duct assembly, wherein the battery swap box is formed by at least two boxes being spliced ​​together from top to bottom, and at least two of the boxes have a connecting portion that communicates with each other from top to bottom; the air duct assembly is arranged in the connecting portion and passes through the at least two boxes, and the air duct assembly is used to connect to the air inlet of an air-conditioning device.

[0008] This solution is assembled by assembling at least two battery exchange boxes separately. The air duct assembly is used to extend between the boxes to realize air circulation in all the battery exchange boxes. As a result, the air conditioning equipment can be used to centrally cool the battery exchange boxes. Not only does it improve the cooling efficiency, it can also increase the coverage of the air conditioning equipment to avoid heat concentration.

[0009] Preferably, the battery exchange box includes an upper box and a lower box, and the air duct assembly has a stretchable air supply pipe, which is arranged in the upper box or the lower box. After the upper box and the lower box are spliced, the air supply pipe is stretched so that the air supply pipe extends from the upper box to the lower box; or the air supply pipe is stretched so that the air supply pipe extends from the lower box to the upper box.

[0010] By stretching the air supply pipe, the height between the upper box body and the lower box body can be adapted, thereby realizing the extended arrangement of the air duct assembly in the upper box body and the lower box body.

[0011] Preferably, the battery exchange box includes an upper box and a lower box, at least a portion of the air duct assembly is located in the upper box and at least a portion of the air duct assembly is located in the lower box, and the two portions located in the upper box and the lower box are connected by a connecting assembly to form the air duct assembly.

[0012] The air duct assembly is assembled by assembling the upper box and the lower box separately. The two parts of the air duct assembly are pre-assembled in the upper box and the lower box, and only need to be sealed and connected by the connecting assembly during splicing, thereby reducing installation time and improving efficiency.

[0013] Preferably, the air duct assembly includes a down duct and an up duct, the down duct is connected to the lower box, the up duct is connected to the upper box, and the connecting assembly is arranged in a vertical direction and connected to the down duct and the up duct respectively.

[0014] The connecting component matches the height difference between the upper air duct and the lower air duct by extending longitudinally, thereby realizing the connection between the upper air duct and the lower air duct. The upper air duct and the lower air duct can be arranged in advance in the upper box and the lower box, and when the upper box and the lower box are connected, it does not affect other internal arrangements, and only needs to overlap the connecting component in the longitudinal direction.

[0015] Preferably, one end of the connecting component is connected to the downwind duct or the upwind duct, and the other end of the connecting component is connected to the upwind duct or the downwind duct, and the connecting component is a retractable component to seal and connect the upwind duct and the downwind duct.

[0016] The height of the retractable part itself is adjustable, thereby being able to adapt to the distance between the upper air duct and the lower air duct, and being able to be adjusted when there is an error between the actual distance between the two and the theoretical distance.

[0017] Preferably, the connection component is one or more of an accordion hose, a bellows or a telescopic air duct.

[0018] Preferably, the connecting component is a flexible member, one end of the connecting component is connected to the downwind duct, and the other end of the connecting component is connected to the upwind duct, and the connecting component adapts to the docking position between the downwind duct and the upwind duct by deforming itself.

[0019] The flexible member itself is bendable, so that when there is an error between the actual distance between the upper air duct and the lower air duct and the designed distance, it can also be adaptively adjusted through deformation.

[0020] Preferably, the upper air duct and the lower air duct respectively have at least a vertical air duct section extending in a vertical direction at the communicating portion, and the connecting component is connected between the vertical air duct sections of the upper air duct and the lower air duct.

[0021] The vertical air duct sections of the upper air duct and the lower air duct can be arranged in advance in the upper box and the lower box. When the upper box and the lower box are connected, it is only necessary to complete the connection between the upper air duct and the lower air duct. Fewer parts are affected by the construction.

[0022] Preferably, the upper air duct and the lower air duct are rigid structures at least in the vertical air duct section, and the connecting component is a flexible or retractable component, and the connecting component deforms itself to seal and connect the vertical air duct sections of the upper air duct and the lower air duct.

[0023] The rigid vertical air duct section is more durable and beautiful. Only a small section of the overall air duct assembly is a flexible or retractable part, so the whole is more solid.

[0024] Preferably, a filter is detachably connected to the vertical air duct section of the upper air duct or the lower air duct, and the filter blocks the air path in the upper air duct or the lower air duct and is used to filter the air.

[0025] A filter is provided in the air duct assembly to ensure the cleanliness of the air flowing out of the air outlet.

[0026] Preferably, a connecting groove and an insertion port are provided on the vertical air duct section, the filter screen is inserted into the vertical air duct section through the connecting groove, the filter screen is detachably connected to the connecting groove, and the connecting groove is formed to be inclined upward from the insertion port.

[0027] This makes it easy for the user to pull the filter downward from the outside, and when installing, it is easy to push the filter upward, and the filter is also tilted accordingly, which can increase the contact area and improve filtering efficiency.

[0028] Preferably, the battery swap station or energy storage station also includes air-conditioning equipment, which is arranged on the upper box body; the interior of the battery swap box body includes a battery storage area for storing batteries and penetrating the upper box body and the lower box body from top to bottom, the air outlet of the air-conditioning equipment is arranged at the top of the battery storage area, and the air inlet of the air duct assembly is arranged at the bottom of the battery storage area and extends to the air inlet connected to the air-conditioning equipment, so that air circulation is formed between the air-conditioning equipment and the battery storage area.

[0029] The air conditioning device is pre-installed on the upper box body, which can reduce the time of subsequent installation. The air outlet of the air conditioning device and the air inlet of the air duct component are respectively arranged above and below the charging position, so that the air from the air outlet can flow through the charging position as much as possible.

[0030] Preferably, at least two groups of charging racks are provided in the battery storage area, wherein the air outlets of the air-conditioning equipment extend in different directions, and the air outlets of the air-conditioning equipment are at least located at the top of the interval space between the charging racks and / or above the charging racks.

[0031] As a result, the air outlet of the air-conditioning equipment can cover more locations while avoiding the space above the battery transfer equipment between the charging racks to avoid structural interference.

[0032] Preferably, the interior of the battery-changing box also includes a battery-changing operation area for replacing the battery of the electric vehicle, the battery-changing operation area is located on one side of the battery storage area, and the air duct assembly is arranged in the area between the charging rack and the battery-changing operation area.

[0033] Preferably, the air duct assembly is attached to the wall plate between the battery swapping operation area and the battery storage area, and its width is adapted to the width of the charging rack. Thus, the air duct assembly can not only circulate air, but also physically separate the battery storage area from the battery swapping operation area, so that the interior of the battery storage area can be kept closed and refrigerated to ensure the refrigeration effect.

[0034] Preferably, an adjustable air inlet opening is provided on the upper air duct or the lower air duct, and the adjustable air inlet opening and the air duct assembly together supply air to the air inlet of the air-conditioning device, so that the air intake of the air-conditioning device is greater than the air outlet.

[0035] The battery swap channel is normally open or opened when the battery swap equipment enters or exits. Therefore, the air is taken in through the adjustable air intake opening so that the air intake of the air-conditioning equipment is greater than the air outlet, causing internal positive pressure, making it difficult for outside air to enter from the battery swap channel.

[0036] The positive and progressive effect of the present invention is that the upper and lower splicing design of the battery swap box of the present invention is divided into upper and lower parts of the box, which are installed and transported independently of each other, meeting the requirements of road transportation, while simplifying installation and disassembly, and facilitating on-site installation and commissioning. The splicing of the upper and lower boxes allows the battery swap station or energy storage station to have a larger longitudinal space, which can reduce the floor space and improve land utilization. In addition, the air duct assembly forms an air circulation path with the air-conditioning equipment at the connecting part of the upper and lower boxes, covering the longitudinal space of the entire battery swap station or energy storage station, improving the temperature regulation efficiency of the entire battery swap station or energy storage station, and avoiding heat concentration.

[0046] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0047] Example 1

[0048] like Figure 1-Figure 8As shown, this embodiment discloses a battery swap station or energy storage station, including air conditioning equipment and air duct assembly 4. In this embodiment, the battery swap station is further discussed, but this embodiment and other preferred embodiments can be directly used as an energy storage station or used as an energy storage station after adaptive adjustment. Figure 1 and Figure 2 As shown, the battery replacement box of this embodiment is composed of two boxes in the height direction, namely an upper box 12 and a lower box 11, which are spliced ​​up and down, and there is a connecting part between at least the two boxes.

[0049] like Figure 2 and 3 As shown, in a preferred embodiment, the battery swap box of the battery swap station includes a battery swap operation area 101 for replacing battery packs and a battery storage area 102 for charging and storing battery packs in the lateral direction, and the battery swap operation area 101 is arranged on one side of the battery storage area 102. Among them, the battery swap operation area 101 and the battery storage area 102 are connected through a battery swap channel 103. The battery swap equipment shuttles back and forth through the battery swap channel 103. In some embodiments of the energy storage station, the energy storage station may only include the battery storage area 102, excluding the battery swap channel 103 and the battery swap operation area.

[0050] like Figure 3-Figure 5 As shown, in a preferred embodiment, the air duct assembly 4 is arranged at the connecting part and penetrates the upper box body 12 and the lower box body 11 at least two boxes, and the air duct assembly 4 is used to connect with the air inlet of the air conditioning equipment. The upper air duct 42 of the air duct assembly 4 is located in the upper box body 12 and the lower air duct 41 is located in the lower box body 11. Specifically, the lower air duct 41 is connected to the lower box body 11, the upper air duct 42 is connected to the upper box body 12, and the connecting assembly 43 is arranged in the vertical direction and connected to the lower air duct 41 and the upper air duct 42 respectively. The air duct assembly 4 is connected through the connecting assembly 43 to form an integrally connected air duct assembly 4.

[0051] In the above preferred embodiment, at least two battery exchange boxes are assembled separately and then assembled. The air duct assembly 4 is used to extend between the upper box 12 and the lower box 11 to realize air circulation in the upper box 12 and the lower box 11. In this way, the upper box 12 and the lower box 11 can be centrally cooled by air conditioning equipment. Not only does it improve the cooling efficiency, it can also increase the coverage of the air conditioning equipment to avoid heat concentration.

[0052] like Figure 3-Figure 5As shown, in a preferred embodiment, the air duct assembly 4 is assembled by assembling the upper box 12 and the lower box 11 respectively. Among them, the two parts of the air duct assembly 4 are pre-assembled in the upper box 12 and the lower box 11, and only need to complete the sealing connection through the connecting assembly 43 during splicing, thereby reducing the installation time and improving efficiency. In some embodiments, the connecting member 43 can be a flange, or one or more of a hard pipe hose, a corrugated pipe, and the upper air duct 42 and the lower air duct 41 are connected together by docking, threaded fastening or welding.

[0053] like Figure 4-Figure 5 As shown, in a preferred embodiment, the connection component 43 matches the height difference between the upper air duct 42 and the lower air duct 41 by extending longitudinally, thereby achieving the connection between the upper air duct 42 and the lower air duct 41. The upper air duct 42 and the lower air duct 41 can be arranged in advance in the upper box 12 and the lower box 11, and when the upper box 12 and the lower box 11 are connected, it does not affect other internal arrangements, and only needs to overlap the connection component 43 in the longitudinal direction.

[0054] like Figure 3-Figure 6 As shown, in a further preferred embodiment, the connection component 43 is a retractable component to seal and connect the upper air duct 42 and the lower air duct 41. The retractable component itself is height-adjustable, thereby adapting to the distance between the upper air duct 42 and the lower air duct 41, and can also be adjusted when there is an error between the actual distance between the two and the theoretical distance. Further, the connection component 43 of this embodiment can be one or more of an accordion hose, a bellows, or a telescopic air duct.

[0055] like Figure 3-Figure 5 As shown, in a preferred embodiment, the upper air duct 42 and the lower air duct 41 respectively have at least a vertical air duct section extending in the vertical direction at the communicating part, and the connecting component 43 is connected between the vertical air duct sections of the upper air duct 42 and the lower air duct 41. The vertical air duct sections of the upper air duct 42 and the lower air duct 41 can be arranged in advance in the upper box 12 and the lower box 11. When the upper box 12 and the lower box 11 are connected, it is only necessary to complete the connection between the upper air duct 42 and the lower air duct 41. Fewer parts are affected by the construction.

[0056] In a further preferred embodiment, the upper air duct 42 and the lower air duct 41 are rigid structures at least in the vertical air duct section, and the connecting component 43 is a flexible or retractable component. The connecting component 43 deforms itself to seal and connect the vertical air duct sections of the upper air duct 42 and the lower air duct 41. The rigid vertical air duct section is more durable and beautiful. Only a small section of the overall air duct assembly 4 is a flexible or retractable component, so the overall structure is more solid.

[0057] like Figure 3-Figure 5As shown, in a preferred embodiment, the air-conditioning equipment includes an air-conditioning indoor unit 31 and an air-conditioning outdoor unit 32, and the air-conditioning equipment is arranged in the upper box body 12; the interior of the battery exchange box body includes a battery storage area for storing batteries and penetrating the upper box body 12 and the lower box body 11 from top to bottom, the air outlet 311 and the air outlet 312 of the air-conditioning equipment are arranged at the top of the battery storage area 102, and the air inlet of the air duct assembly 4 is arranged at the bottom of the battery storage area 102 and extends to the air inlet connected to the air-conditioning indoor unit 31, so that air circulation is formed between the air-conditioning indoor unit 31 and the battery storage area 102.

[0058] In a preferred embodiment, the air conditioner outdoor unit 42 and the air conditioner indoor unit 41 are pre-installed on the upper box body 12, which can reduce the time of subsequent installation. The air outlet of the air conditioner indoor unit 41 and the air inlet of the air duct assembly 4 are respectively arranged above and below the charging position, so that the air from the air outlet can flow through the charging position as much as possible.

[0059] like Figure 3 As shown, in a preferred embodiment, a filter screen 6 is provided in the upper air duct 42 or the lower air duct 41 of the air duct assembly 4, and the filter screen 6 ensures the cleanliness of the air flowing out of the air outlet. Specifically, a connecting groove and an insertion port are provided on the vertical air duct section of the upper air duct 42 and the lower air duct 41, and the filter screen is inserted into the vertical air duct section through the connecting groove. The filter screen is detachably connected to the connecting groove, and the connecting groove is formed by tilting upward from the insertion port. This makes it convenient for the user to pull the filter screen downward from the outside, and when installing, it is convenient to push the filter screen upward, and the filter screen is also tilted accordingly, which can increase the contact area and improve the filtering efficiency. Of course, in other embodiments, the filter screen 6 can also be connected in other ways, such as directly fixed, or can be adsorbed by magnetic suction, or connected by snap-on.

[0060] like Figure 7 As shown, the battery storage area 102 of this embodiment is provided with a battery transfer device 2 and at least two groups of charging racks 5, wherein the air outlet 311 and the air outlet 312 of the air conditioner indoor unit 31 extend in different directions, and the air outlet 312 of the air conditioner indoor unit 31 is located on the side of the top of the interval space between the charging racks 5, and the air outlet 311 is located above the charging racks. As a result, the air outlet of the air conditioner indoor unit 31 can cover more positions while avoiding the space above the battery transfer device 2 between the charging racks to avoid structural interference. In other embodiments, it can also be set as a multi-row charging rack 5 or a single-row charging rack 5. The battery transfer device 2 can be a palletizer that can move in the horizontal and vertical directions, or it can also be a device that is set to move and transport batteries only in the vertical direction, or it can be a device that is set to move and transport batteries only in the horizontal direction.

[0061] Most of the upper duct 42 and the lower duct 41 of the duct assembly 4 of this embodiment are longitudinal ducts, and the longitudinal ducts of the upper duct 42 and the lower duct 41 extend in the space between the battery storage area 102 and the battery swapping operation area 101. The longitudinal ducts are attached to the wall panels between the battery swapping operation area 101 and the battery storage area 102 and are adapted to the width of the charging rack 5. Therefore, the duct assembly 4 can not only circulate air, but also physically separate the battery storage area 102 and the battery swapping operation area 101, so that the interior of the battery storage area 102 can maintain closed refrigeration to ensure the refrigeration effect.

[0062] In a preferred embodiment, an adjustable air inlet opening is provided on the upper air duct 42 or the lower air duct 41 of this embodiment, and the adjustable air inlet opening and the air duct assembly 4 jointly supply air to the air inlet of the air conditioning device, so that the air intake of the air conditioning device is greater than the air outlet. The battery exchange channel 103 is normally open or opened when the battery exchange device enters and exits, so the air intake of the air conditioning device is greater than the air outlet by taking air through the adjustable air inlet opening, resulting in internal positive pressure, so that it is not easy for external air to enter from the battery exchange channel.

[0063] Example 2

[0064] like Figure 8 As shown, the battery swap box of the battery swap station or energy storage station in this embodiment also includes an upper box 12 and a lower box 11. The difference between this embodiment and embodiment 1 is that the air duct assembly 4 has a stretchable air supply pipe 40.

[0065] The air supply pipe 40 of this embodiment is arranged in the upper box 12 or the lower box 11. After the upper box 12 and the lower box 11 are spliced, the air supply pipe 40 is stretched so that the air supply pipe extends from the upper box 12 to the lower box 11; or the air supply pipe is stretched so that the air supply pipe 40 extends from the lower box 11 to the upper box 12. By stretching the air supply pipe 40, the height between the upper box 12 and the lower box 11 can be adapted, and the air duct assembly 4 is extended in the upper box 12 and the lower box 11.

[0066] Example 3

[0067] like Fig. 9 As shown, the difference between this embodiment and embodiment 1 is that the connection component 43 of this embodiment is a flexible member, one end of the connection component 43 is connected to the lower air duct 41, and the other end of the connection component 43 is connected to the upper air duct 42, and the connection component 43 deforms itself to adapt to the docking position between the lower air duct 41 and the upper air duct 42. The flexible member itself is bendable, so when there is an error between the actual distance between the upper air duct 42 and the lower air duct 41 and the designed distance, it can also be adaptively adjusted through deformation.

[0068] The design of the upper and lower splicing of the battery swap box of the present invention is divided into two parts, the upper and lower parts of the box, which are installed and transported independently of each other, meeting the requirements of road transportation, while simplifying installation and disassembly, and facilitating on-site installation and commissioning. The splicing of the upper and lower boxes allows the battery swap station or energy storage station to have a larger longitudinal space, which can reduce the floor space and improve land utilization. In addition, the air duct assembly forms an air circulation path with the air-conditioning equipment at the connecting part of the upper and lower boxes, covering the longitudinal space of the entire battery swap station or energy storage station, thereby improving the temperature regulation efficiency of the entire battery swap station or energy storage station and avoiding heat concentration.
