Each new energy energy storage cabinet or energy storage prefabricated cabin has multiple energy storage units. The temperature difference between multiple energy storage units needs to be within a reasonable temperature range to achieve the best performance. Currently, various air ducts are usually used to introduce cold air into the battery pack for heat dissipation. However, most of the traditional air duct flow equalization methods are macroscopic direction regulation to overall reduce the temperature difference between energy storage units in the new energy energy storage cabinet or energy storage prefabricated cabin. This method is difficult to achieve precise temperature control, resulting in insufficient flexibility and freedom in temperature regulation. Summary of the Utility Model

[0007] A plurality of battery packs, the plurality of battery packs are respectively arranged in the plurality of accommodation cavities. The first side of each battery pack is close to the air return port, and a heat exchange air outlet and an adjustable air inlet are provided on the first side of each battery pack. The heat exchange air outlet is used to discharge the air in the battery pack outward for heat exchange work;

[0008] By adjusting the air outlet size of the adjustable air inlet, the air volume entering the corresponding battery pack through the adjustable air inlet is controlled to adjust the heat exchange air volume.

[0009] Optionally, the adjustable air inlet includes an air outlet mesh and a mesh flow equalization plate, and the mesh flow equalization plate is movably installed in the mesh.

[0010] Optionally, both the air outlet mesh and the mesh flow equalization plate have a plurality of air outlet holes. The mesh flow equalization plate is installed on the air outlet mesh through a plurality of fixing members, and the size of each fixing member is smaller than the size of the air outlet hole.

[0011] Optionally, the air outlet hole is a long strip-shaped air outlet hole, and the diameter of the fixing member is equal to the width of the long strip-shaped air outlet hole.

[0012] Optionally, the air outlet holes are elongated air outlet holes, and the diameter of the fixing member is smaller than the length of the elongated air outlet holes, so that after the mesh flow equalizing plate is installed in the air outlet mesh holes, the mesh flow equalizing plate can move along the length direction of the elongated air outlet holes to adjust the heat exchange air volume of the battery pack.

[0013] Optionally, the shape and size of each air outlet hole are the same.

Therefore, each battery pack in the present utility model includes a heat exchange air outlet and an adjustable air inlet. The heat exchange air outlet is used to discharge hot air, and the adjustable air inlet is used to increase the air intake. Since the heat exchange air volume is equal to the air volume discharged from the heat exchange air outlet minus the air volume introduced into the adjustable air inlet, thus, by adjusting the adjustable air inlet, the control of the heat exchange air volume can be achieved, and the cooling effect of each battery pack can be dynamically adjusted according to actual needs, thereby realizing more accurate and flexible temperature control.

[0029] In a new energy energy storage cabinet or an energy storage prefabricated cabin, the battery pack serves as a basic energy storage unit. Each new energy energy storage cabinet or energy storage prefabricated cabin has multiple energy storage units. The temperature difference between multiple energy storage units needs to be within a reasonable temperature range to achieve the best performance. Currently, various air ducts are usually used to introduce cold air into the battery pack for heat dissipation. However, most of the traditional air duct methods for achieving uniform flow are macroscopic direction control to overall reduce the temperature difference between the energy storage units in the new energy energy storage cabinet or energy storage prefabricated cabin. This method is difficult to achieve precise temperature control, resulting in insufficient flexibility and freedom in temperature regulation.

[0030] For this reason, the present utility model proposes a new energy energy storage cabinet, aiming to improve the accuracy of temperature regulation while also enhancing the flexibility and freedom of temperature regulation. In an embodiment, the new energy energy storage cabinet includes a battery rack 100, an air conditioner 200, and multiple battery packs 300. The battery rack 100 has a plurality of accommodation cavities 110 arranged at intervals along the length direction; the air conditioner 200 has an air outlet 210 and an air return opening 220. The air outlet 210 is provided at one end of the battery rack 100, and the air return opening 220 is provided on one side of the battery rack 100; multiple battery packs 300, the multiple battery packs 300 are respectively arranged in the plurality of accommodation cavities 110 in a one-to-one correspondence. The first side of each battery pack 300 is close to the air return opening 220, and a heat exchange air outlet 310 and an adjustable air inlet 320 are provided on the first side of each battery pack 300. The heat exchange air outlet 310 is used to discharge the air inside the battery pack 300 outward for heat exchange work; by adjusting the air outlet size of the adjustable air inlet 320, the air volume entering the corresponding battery pack 300 through the adjustable air inlet 320 is controlled to adjust the heat exchange air volume.

[0031] In this embodiment, a plurality of accommodation cavities 110 are arranged at intervals along the length direction of the battery rack 100 for placing the battery packs 300. This design not only ensures the orderly arrangement of the battery packs 300 in the physical space but also provides convenience for subsequent temperature regulation. It can be understood that the battery rack 100, as a platform for supporting and separating the battery packs 300, its structural layout directly affects the air duct design and the uniformity of temperature distribution.

[0032] Optionally, the battery rack 100 can be multi-layered or single-layered; for the accommodation cavities 110 in the single-layer battery rack 100, they can be arranged at intervals along the horizontal direction; for the accommodation cavities 110 in the multi-layer battery rack 100, they can be arranged at intervals along the vertical (length) direction. At the same time, each layer in the multi-layer battery rack 100 can have more than one accommodation cavity 110 arranged at intervals along the horizontal direction, that is, each layer of the battery rack 100 can be provided with a plurality of accommodation cavities 110.

[0033] Optionally, in some examples, the battery rack 100 is made of metals such as iron and aluminum into an open-frame structure; in some examples, the battery rack 100 is an enclosed box body as a whole, and multiple layers of partitions or drawer-type structures can be arranged inside for placing the battery packs 300; in some examples, the shape of the battery rack 100 is customized according to specific requirements and can be adjusted according to factors such as the specifications of the battery packs 300, the layout of the energy storage system, and the installation environment.

[0034] In this embodiment, the air conditioner 200 is the core temperature control device in the new energy energy storage cabinet, and has an air outlet 210 and an air return port 220. The air outlet 210 is arranged at one end of the battery rack 100 and is responsible for blowing cold air into the inside of the battery rack 100; the air return port 220 is arranged on one side of the battery rack 100 for recovering and processing the overheated air. It can be understood that the air conditioner 200 realizes the temperature adjustment inside the energy storage cabinet by circulating and providing cold air and recovering hot air.

[0035] In this embodiment, the battery pack 300 is the basic energy storage unit in the new energy energy storage cabinet, and multiple battery packs 300 are respectively placed in the accommodation cavity 110 of the battery rack 100. Each battery pack 300 generates heat during operation, so effective heat dissipation measures are required.

[0036] In this embodiment, each battery pack 300 has a heat exchange air outlet 310, which is designed on its first side and is close to the air return port 220 of the battery rack 100. The function of the heat exchange air outlet 310 is to discharge the hot air inside the battery pack 300 for heat exchange with the external environment. In this way, using the cold air provided by the air conditioner 200, through the air circulation inside the battery pack 300, the heat generated during battery operation is taken away, so as to keep the temperature inside the battery pack 300 within a reasonable range. The size and position of the heat exchange air outlet 310 are optimized to ensure that the air flow can effectively flow from the inside of the battery pack 300 to the air return port 220 without causing unnecessary air flow blockage.

[0037] In this embodiment, each battery pack 300 has an adjustable air inlet 320, and the adjustable air inlet 320 is arranged on the first side of each battery pack 300 (i.e., the side close to the air return port 220), but is arranged adjacent to and separated from the heat exchange air outlet 310. The function of the adjustable air inlet 320 is to control the amount of cold air entering the inside of the battery pack 300. By adjusting the adjustable air inlet 320, the cooling air volume of each battery pack 300 can be precisely controlled, so as to achieve precise control of the temperature of the battery pack 300. This design allows dynamic adjustment according to the actual working state and temperature requirements of the battery pack 300 to ensure that each battery pack 300 can be maintained within the optimal working temperature range.

[0038] It can be understood that the adjustable air inlet 320 can use variable vanes, sliding covers or other adjustment devices.

[0039] It should be noted that the heat exchange air volume is equal to the air volume discharged from the heat exchange air outlet 310 minus the air volume introduced into the adjustable air inlet 320.

[0040] In summary, the present utility model proposes a new energy energy storage cabinet, aiming to improve the accuracy of temperature control while also enhancing the flexibility and freedom of temperature control. Specifically, this new energy energy storage cabinet includes a battery rack 100 and battery packs 300 provided on the battery rack 100. The battery rack 100 is cooled by an air conditioner 200. However, the air conditioner 200 uses a macroscopic air duct control method and cannot accurately control the temperature inside each battery pack 300. Therefore, in the present utility model, each battery pack 300 includes a heat exchange air outlet 310 and an adjustable air inlet 320. The heat exchange air outlet 310 is used to discharge hot air, and the adjustable air inlet 320 is used to increase the air intake. Since the heat exchange air volume is equal to the air volume discharged from the heat exchange air outlet 310 minus the air volume introduced into the adjustable air inlet 320, thus, by adjusting the adjustable air inlet 320, the control of the heat exchange air volume can be achieved, and the cooling effect of each battery pack 300 can be dynamically adjusted according to actual needs, thereby achieving more accurate and flexible temperature control.

[0041] In one embodiment, the adjustable air inlet 320 includes an air outlet mesh 321 and a mesh flow equalizing plate 322, and the mesh flow equalizing plate 322 is movably installed in the mesh.

[0042] In this embodiment, in order to achieve precise control of the cold air volume entering the battery pack 300, the adjustable air inlet 320 is designed to include two parts: an air outlet mesh 321 and a mesh flow equalizing plate 322. The air outlet mesh 321 refers to the openings on the outer shell of the battery pack 300, and these openings allow external cold air to flow into the interior of the battery pack 300. The mesh flow equalizing plate 322 is a component installed on the air outlet mesh 321, and it can change its position or opening degree in a movable manner (such as rotation, sliding or other mechanical adjustment methods), thereby changing the air flow rate through the mesh.

[0043] Specifically, the function of the mesh flow equalizing plate 322 is to ensure uniform air distribution while also being able to adjust the air volume entering the battery pack 300 as needed. When it is necessary to increase the cooling effect, the position of the mesh flow equalizing plate 322 can be adjusted to increase the air intake area, so that more cold air enters the battery pack 300; conversely, when it is necessary to reduce the cooling effect, the mesh flow equalizing plate 322 can be adjusted to reduce the air intake area, thereby reducing the amount of cold air entering.

[0044] In this way, not only can the air volume be adjusted, but also the uniform distribution of the cold air entering the battery pack 300 can be ensured, thereby improving the consistency of the cooling effect and avoiding the problems of overcooling or overheating in certain areas.

[0045] In one embodiment, the air outlet mesh holes 321 and the mesh flow equalizing plate 322 both have a plurality of air outlet holes 323. The mesh flow equalizing plate 322 is installed on the air outlet mesh holes 321 through a plurality of fixing members 324, and the size of each fixing member 324 is smaller than the size of the air outlet holes 323.

[0046] In this embodiment, the air outlet mesh holes 321 refer to the air outlet holes 323 designed on the outer shell of the battery pack 300. These air outlet holes 323 allow the external cold air to enter the interior of the battery pack 300 to help the battery pack 300 dissipate heat, thereby maintaining the temperature inside the battery pack 300 within a reasonable range.

[0047] In this embodiment, the mesh flow equalizing plate 322 is installed on the air outlet mesh holes 321 and itself also has a plurality of air outlet holes 323. The main function of the mesh flow equalizing plate 322 is to further equalize the air flow entering the battery pack 300 and can adjust the air volume entering the battery pack 300 according to actual needs. By adjusting the position or opening degree of the mesh flow equalizing plate 322, the amount of cold air entering the interior of the battery pack 300 can be controlled, thereby achieving precise control of the temperature of the battery pack 300.

[0048] In this embodiment, the mesh flow equalizing plate 322 is installed on the air outlet mesh holes 321 through a plurality of fixing members 324. These fixing members 324 can be screws, clips or other types of connecting devices, which are used to ensure that the mesh flow equalizing plate 322 is firmly installed in the correct position. It is worth noting that the size of each fixing member 324 is smaller than the size of the air outlet holes 323. Such a design is to ensure that the mesh flow equalizing plate 322 still has some movement space after installation. That is to say, although the mesh flow equalizing plate 322 is fixed by the fixing members 324, it can still move or rotate within a certain range, so that its position or opening degree can be adjusted according to needs to control the air flow entering the battery pack 300.

[0049] In this way, by giving the mesh flow equalizing plate 322 a certain amount of movement space, its position can be adjusted without disassembling the fixing members 324, so as to dynamically adjust the amount of cold air entering according to the working state of the battery pack 300. While improving the accuracy of temperature control, it also improves the flexibility and freedom of temperature control.

[0050] In one embodiment, the air outlet holes 323 are long strip-shaped air outlet holes 323, and the diameter of the fixing members 324 is equal to the width of the long strip-shaped air outlet holes 323.

[0051] The diameter of the fixing member 324 is equal to the width of the elongated air outlet hole 323, which can ensure that the fixing member 324 can firmly fix the mesh flow equalizing plate 322 during installation, preventing it from loosening or falling off during use. At the same time, the controllability of the mesh flow equalizing plate 322 is improved, thereby improving the accuracy of temperature regulation.

[0052] In one embodiment, the air outlet hole 323 is an elongated air outlet hole 323, and the diameter of the fixing member 324 is smaller than the length of the elongated air outlet hole 323, so that after the mesh flow equalizing plate 322 is installed on the air outlet mesh 321, the mesh flow equalizing plate 322 can move along the length direction of the elongated air outlet hole 323 to adjust the heat exchange air volume of the battery pack 300.

[0053] It can be understood that although the diameter of the fixing member 324 is equal to the width of the elongated air outlet hole 323, due to the elongated design of the air outlet hole 323, the fixing member 324 can have a certain movement space in the length direction of the elongated air outlet hole 323. In this way, even if the fixing member 324 fixes the mesh flow equalizing plate 322, the mesh flow equalizing plate 322 can still move in the length direction of the elongated air outlet hole 323, thereby realizing fine adjustment of the air volume entering the battery pack 300.

[0054] In one embodiment, the shape and size of each air outlet hole 323 are the same.

[0055] In this embodiment, the air outlet holes 323 on the mesh flow equalizing plate 322 and the air outlet holes 323 on the air outlet mesh 321 have the same geometric shape. For example, if the air outlet holes 323 of the air outlet mesh 321 are designed to be elongated, then the air outlet holes 323 on the mesh flow equalizing plate 322 will also be elongated. At the same time, in addition to the same shape, the sizes of these air outlet holes 323 are also the same. This means that whether it is the air outlet holes 323 on the mesh flow equalizing plate 322 or the air outlet holes 323 on the air outlet mesh 321, their sizes are consistent. In this way, it helps to ensure that the air flow can be evenly distributed when entering the battery pack 300, avoiding reducing the regulation accuracy due to shape differences.

[0056] In one embodiment, each heat exchange air outlet 310 is provided with a fan 311, and the fan 311 is used to discharge the air in the battery pack 300 outward.

[0057] A fan 311 is installed at each heat exchange air outlet 310. The main function of the fan 311 is to actively extract and discharge the hot air in the battery pack 300 outward. Compared with the passive heat dissipation method, the fan 311 can accelerate the air flow and improve the heat dissipation efficiency, ensuring that the temperature inside the battery pack 300 can be quickly reduced to the safe range.

[0058] Optionally, the fan 311 can be controlled by a main control module to determine the duty cycle corresponding to each fan 311, so as to adjust the speed of the fan 311 according to the working state of the battery pack 300, thereby controlling the amount of discharged air and achieving precise control of the temperature of the battery pack 300.

[0059] In one embodiment, the battery rack 100 is a multi-layer battery rack 100, and each layer of the multi-layer battery rack 100 has at least two of the accommodation cavities 110.

[0060] The battery rack 100 is designed as a multi-layer structure, separated by partitions or other structures between each layer, forming multiple levels in the vertical direction. The advantage of this design is that it can make full use of the vertical space, improve the space utilization rate of the energy storage cabinet, and is suitable for arranging more battery packs 300 on limited ground, thereby increasing the energy storage capacity. Then, each layer of the battery rack 100 can install more than one battery pack 300. In this way, the horizontal space can be fully utilized, and the space utilization rate of the energy storage cabinet can be improved.

[0061] In one embodiment, the accommodation cavity 110 is also used for installing the PCS component 400.

[0062] The PCS component 400 usually includes devices such as an inverter, a rectifier, and a converter. These devices are responsible for converting the direct current (DC) stored in the battery into alternating current (AC), or vice versa, to meet the needs of the power grid or load. Integrating the PCS component 400 into the accommodation cavity 110 of the battery rack 100 can simplify the overall layout of the system and improve the integration degree of the system.

[0063] It can be understood that each PCS component 400 can also include the heat exchange air outlet 310 and the adjustable air inlet 320 as described in any one of the above. In this way, precise control of the temperature of the PCS component 400 can also be achieved, enabling high-degree-of-freedom and high-flexibility control.

[0064] In one embodiment, it further includes a housing, and the battery rack 100, the air conditioner 200, and the multiple battery packs 300 are all arranged inside the housing.

[0065] It can be understood that the housing mentioned in this embodiment is a structure that encapsulates the entire energy storage system, which includes the battery rack 100, the air conditioner 200, and the multiple battery packs 300. The housing not only provides physical protection but also plays a role in isolating the external environment, ensuring the safe and stable operation of the internal components of the system.

[0066] The above are only exemplary embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included within the patent protection scope of the present utility model.
