Description

Technical Field

[0001] The present application relates to the field of energy storage containers, and in particular to an energy storage container. Background Art

[0002] The use scenarios of energy storage containers cover commercial supporting, power generation and frequency regulation supporting, outdoor use supporting, etc. The altitude can reach 2000~4000m, and the temperature range can reach -30℃~55℃. Under the general cooling solution with liquid cooling, it cannot meet the current harsh environmental requirements, so air flow temperature control is generally used to adapt to environmental conditions.

[0003] When the ambient temperature is too high, the battery will generate heat during the charging and discharging process. If the heat dissipation does not meet the requirements or is not timely, it may cause thermal runaway of the battery pack, which will then produce various flammable gases and a large amount of smoke, and then create the risk of combustion and explosion; similarly, when the ambient temperature is low, the battery pack cannot fully meet the charging and discharging requirements in a cold environment. Therefore, it is necessary to accurately control the temperature control of the energy storage container. However, conventional energy storage containers use a central air conditioner and an entire air duct to control the heat dissipation of the battery rack. This method makes it difficult for the battery rack far from the temperature control device and the battery rack close to the temperature control device to obtain the same temperature control ability. As a result, the battery pack temperature on the battery rack in each area is uneven, which in turn reduces the life of the battery pack, and even some battery packs fail directly.

[0051] refer to Figure 1 and Figure 2 As shown, the main function of the energy storage container 10 is to store electrical energy so that it can be released when needed to supply the power grid or equipment. It can help balance the load of the power grid, adjust the stability of power supply, cope with peak power consumption periods, provide backup power, and support the stable access of renewable energy. The use scenarios of the energy storage container 10 cover commercial supporting, power generation and frequency regulation supporting, outdoor use supporting, etc. The layout altitude can reach 2000~4000m, and the temperature range can reach -30℃~55℃. Under the general solution of using liquid as a temperature adjustment measure, it cannot meet the current harsh environmental requirements, so airflow temperature adjustment is generally used to adapt to environmental conditions.

[0052] The energy storage container 10 includes an air duct 100, a battery rack 200, and a temperature control device 300. The battery rack 200 is provided with a plurality of battery packs, and the temperature control device 300 delivers airflow to the battery rack 200 through the air duct 100, thereby adjusting the temperature of the battery packs to keep the battery packs at a suitable working temperature.

[0053] The existing energy storage container 10 generally adopts a centralized temperature control device 300 and a wind duct 100 corresponding to multiple battery racks 200 for temperature control. This method makes it difficult for the battery racks 200 far from the temperature control device 300 and the battery racks 200 close to the temperature control device 300 to obtain the same temperature control ability. As a result, the battery packs on the battery racks 200 in different areas are unevenly heated, which in turn reduces the life of the battery packs, and even causes some battery packs to fail directly.

[0054] The present application provides an energy storage container 10, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the energy storage container 10 includes: a plurality of air ducts 100, a plurality of battery racks 200 and a plurality of temperature control devices 300. Figure 5 and Figure 6 As shown, the air duct 100 includes an air inlet 110 and an air outlet 120; a plurality of battery racks 200 are arranged adjacent to each other, and the air outlet 120 is communicated with the battery racks 200; a plurality of temperature control devices 300 are arranged adjacent to the plurality of battery racks 200, and the temperature control devices 300 are communicated with the air inlet 110; wherein each battery rack 200 is individually matched with at least one air duct 100 and at least one temperature control device 300.

[0055] It should be noted that the temperature regulating device 300 here can be an air conditioner or other device that can cool or heat, and this application does not limit it. When the battery rack 200 is in a state of too high temperature, the temperature regulating device 300 can output a relatively low temperature to the battery rack 200 so that the battery rack 200 is at a suitable temperature; when the battery rack 200 is in a state of too low temperature, the temperature regulating device 300 can output a relatively high temperature to the battery rack 200 so that the battery rack 200 is at a suitable temperature. In addition, each battery rack 200 is individually matched with at least one air duct 100 and at least one temperature regulating device 300, which can include the following three matching methods: 1. One battery rack 200 can be matched with one air duct 100 and one temperature regulating device 300; 2. One battery rack 200 is matched with multiple air ducts 100 and one temperature regulating device 300; 3. One battery rack 200 is matched with one air duct 100 and multiple temperature regulating devices 300. As long as the air duct 100 and the temperature control device 300 are individually matched for each battery rack 200, they all fall within the protection scope of this application.

[0056] Based on the above settings, one battery rack 200 can be matched with at least one temperature control device 300 and one air duct 100, so that each battery rack 200 can be precisely controlled by the temperature control device 300, so that each battery pack on the battery rack 200 is at a suitable temperature, avoiding the problem of uneven temperature of battery packs on the battery rack 200 in different areas caused by a single temperature control device 300 and a single air duct, thereby increasing the life of the battery pack and reducing the failure rate of the battery pack.

[0057] In this embodiment, reference Figure 4 and Figure 5 As shown, the energy storage container 10 includes a box body 400 and a fixing frame 500, a plurality of battery racks 200 are arranged in the box body 400 along the length direction X of the box body 400, and a fixed space 410 located in the box body 400 is provided above the battery rack 200, and the air duct 100 is arranged in the fixed space 410; a fixing member 130 is arranged outside the air duct 100, and the fixing frame 500 fixes the air duct 100 to the box body 400 through the fixing member 130.

[0058] In this embodiment, the air duct 100 is fixed in the box body 400. On the one hand, the air duct 100 can be located inside the box body 400, thereby avoiding problems such as weathering and oxidation caused by the box body 400. On the other hand, the battery rack 200 does not need to directly bear the pressure of the air duct 100, thereby reducing the weight load of the battery rack 200.

[0059] In this embodiment, reference Figure 5 , Figure 6 , Figure 7 As shown, the fixing member 130 includes a first fixing unit 131; the first fixing unit 131 includes a first connecting portion 131A, and at least part of the positive projection of the first connecting portion 131A on the air duct 100 is located outside the air duct 100; the fixing frame 500 is connected to the first fixing unit 131 through the first connecting portion 131A.

[0060] Based on the above arrangement, the first connection portion 131A and the first fixing unit 131 are connected to support the air duct 100, and because at least part of the positive projection of the first connection portion 131A on the air duct 100 is located outside the air duct 100, the corresponding connection point can be found more conveniently during installation.

[0061] In this embodiment, continue to refer to Figure 5 , Figure 6 , Figure 7As shown, the first fixing unit 131 also includes a second connecting portion 131B, which abuts against one end of the air duct 100 close to the battery rack 200, and the orthographic projection of the second connecting portion 131B on the air duct 100 is located inside the air duct 100; there are multiple first connecting portions 131A, and a first connecting portion 131A is fixed to both ends of the second connecting portion 131B.

[0062] In this embodiment, the second connection portion 131B is pressed against the end of the air duct 100 close to the battery rack 200, and the first connection portion 131A is connected to the fixing frame 500. Therefore, after installation, the second connection portion 131B will exert an upward supporting force on the end of the air duct 100 close to the battery rack 200, thereby avoiding the pressure concentration on the side of the air duct 100, thereby improving the durability of the air duct 100.

[0063] In this embodiment, reference Figure 5 , Figure 6 , Figure 7 As shown, the fixing member 130 further includes a second fixing unit 132, which is disposed on the side of the air duct 100, and a fixing frame 500 is fixedly connected to a first fixing unit 131 and a second fixing unit 132. Based on the above configuration, the fixing frame 500 is fixed to the air duct 100 through a first fixing unit 131 and a second fixing unit 132, so that a stronger supporting force can be obtained.

[0064] In this embodiment, continue to refer to Figure 5 , Figure 6 , Figure 7 As shown, the second fixing unit 132 is disposed directly above the first fixing unit 131, the fixing frame 500 is disposed in the vertical direction, and the fixing frame 500 passes through the first connecting portion 131A and is connected to the second connecting portion 131B. Since the second fixing unit 132 is disposed directly above the first fixing unit 131, when the fixing member 130 and the fixing frame 500 cooperate, the fixing frame 500 can be more conveniently positioned and installed.

[0065] refer to Figure 7 As shown, in this embodiment, four corresponding first connection parts 131A can be provided, which are respectively connected to the two ends of the second connection part 131B, so as to form a first fixing unit 131. In addition, four second fixing units 132 are provided corresponding to the first connection part 131A, and the fixing frame 500 is provided with four matching first fixing units 131 and second fixing units 132. In this embodiment, the four corresponding first connection parts 131A and the four second fixing units 132 are provided at positions close to the corners of the air duct 100, so that the first fixing units 131 and the second fixing units 132 can better bear the weight of the air duct 100.

[0066] In one embodiment, reference Figure 8 and Fig. 9 As shown, the energy storage container 10 also includes a U-shaped support member 600, which is arranged between the air duct 100 and the battery rack 200 to support the air duct 100; the U-shaped support member 600 includes a first fixed section 610, a second fixed section 620 and a support section 630, the first fixed section 610 and the second fixed section 620 are arranged parallel to each other, and the support section 630 is connected to the first fixed section 610 and the second fixed section 620 respectively; the first fixed section 610 is fixedly connected to the air duct 100, and the second fixed section 620 is detachably connected to the battery rack 200. The first fixed section 610 and the second fixed section 620 are arranged parallel to each other, ensuring that the air duct 100 and the battery rack 200 can be arranged in parallel.

[0067] In this embodiment, the U-shaped support member 600 is directly used to support the air duct 100, and the U-shaped support member 600 is arranged on the battery rack 200, thereby avoiding the installation of components such as the fixing frame 500 and the fixing member 130 and the assembly process of the fixing frame 500 and the fixing member 130, thereby reducing the manufacturing cost and the installation cost. In addition, the second fixing section 620 is detachably connected to the battery rack 200, which can facilitate the disassembly and replacement between the air duct 100 and the battery rack 200.

[0068] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the energy storage container 10 includes a box body 400, a control unit 700 and connecting wires. A plurality of battery racks 200 are arranged in the box body 400 along the length direction X of the box body 400, and the control unit 700 is arranged adjacent to the box body 400 along the length direction X; the box body 400 is provided with a wire groove 420, the wire groove 420 is arranged on the box body 400 along the length direction X of the box body 400, and the wire groove 420 and the battery rack 200 are arranged adjacent to each other along the width direction of the box body 400; at least part of the connecting wire is arranged in the wire groove 420, and one end of the connecting wire extends to the battery rack 200 and is electrically connected to the battery pack in the battery rack 200, and the other end of the connecting wire extends to the control unit 700 and is electrically connected to the control unit 700.

[0069] It should be noted that the control unit 700 is the control part of the energy storage system, which is used to manage the energy storage and release process inside the energy storage container. The specific functions of the control unit 700 may include: controlling the storage and release of energy, system monitoring and management, data collection and analysis, fault diagnosis and protection, etc. The connecting line is used to transmit information and electric energy in the box 400.

[0070] In this embodiment, the energy storage container 10 is provided with a wire trough 420, and the wire trough 420 is arranged in the box body 400 along the length direction X of the box body 400, so that the originally complicated lines in the box body 400 become clear, thereby facilitating installation and subsequent maintenance work. Figure 3 As shown, the wire groove 420 can also be set at the edge of the box 400, which is more convenient for modification and arrangement.

[0071] In this embodiment, reference Figure 3 As shown, the energy storage container 10 is further provided with an inspection port 900 , which is arranged on the arrangement path of the connecting line and is arranged outside the box body 400 .

[0072] When a line problem occurs in the energy storage container 10, the energy storage container 10 needs to be opened and analyzed one by one. In this embodiment, the inspection port 900 is set on the layout path of the connecting line, so when inspecting or maintaining, it is only necessary to open the inspection port 900 to analyze the connecting lines in the inspection port 900 one by one, thereby avoiding a complicated inspection process. And the inspection port 900 is set outside the box 400, so that when inspecting, there is no need to open the box 400, and the inspection operation can be completed only outside the box 400.

[0073] In this embodiment, reference Figure 3 , Figure 4 , Figure 5 as well as Figure 8 As shown, the battery rack 200 is provided with a plurality of storage spaces 210, and the storage space 210 includes a plurality of battery spaces 211 and at least one transformer space 212, and the transformer space 212 is provided at the end of the battery rack 200 close to the wire slot 420. Among them, the battery space 211 is used to place the battery pack, and the transformer space 212 is used to place the transformer box, and the connection to the control unit 700 is mainly connected from the transformer box. Such a setting makes the transformer space 212 close to the wire slot 420, thereby facilitating the setting of the connecting wire. Figure 8 As shown, the transformer space 212 is disposed at the bottom of the battery rack 200 , and such a configuration facilitates leading the connection wires in the transformer space 212 to the wire slot 420 .
