[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 7 An energy storage system 100 according to an embodiment of the present invention is described.

[0032] like Figure 1 As shown, the energy storage system 100 according to an embodiment of the utility model includes an energy storage box 1 and a water machine component 2.

[0033] Specifically, the energy storage box 1 has a receiving space 11, and the water machine component 2 is arranged in the receiving space 11. The water machine component 2 is located in the length direction of the energy storage box 1 (for example, Figure 1 The left and right directions in the diagram are arranged on one side and adjacent to the top of the energy storage box 1. For example, Figure 1 In the example, the water machine component 2 is located at the upper right position in the accommodating space 11. In this way, the energy storage box 1 has a large space on the left side of the water machine component 2 for installing other components of the energy storage box 1, and the space below the water machine component 2 can also be used to install other components of the energy storage box 1, so that the position of the water machine component 2 is reasonably set, which is conducive to the utilization of the accommodating space 11, improves the volume energy density of the energy storage system 100, and improves the performance of the energy storage system 100. In other words, if the water machine component 2 is set in the middle position of the energy storage box 1 along the left-right direction, it is not conducive to the arrangement and connection of other components in the energy storage box 1.

[0034] According to the energy storage system 100 of the embodiment of the utility model, by arranging the water machine component 2 on one side of the energy storage box 1 in the length direction adjacent to the top of the energy storage box 1, the energy storage box 1 has a larger connected space for installing other components, and the position of the water machine component 2 is reasonably arranged, which is conducive to the utilization of the accommodating space 11, thereby improving the volume energy density of the energy storage system 100 and enhancing the performance of the energy storage system 100.

[0035] According to some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 The energy storage system 100 further includes a combiner cabinet 3, which is disposed on one side of the accommodation space 11 adjacent to the water machine assembly 2, and the combiner cabinet 3 is located below the water machine assembly 2. Figure 1 , Figure 4 and Figure 5 In the example, the junction cabinet 3 and the water machine assembly 2 are located on the same side of the length direction of the energy storage box 1, and the junction cabinet 3 and the water machine assembly 2 are opposite to each other in the up-down direction. As a result, the space below the water machine assembly 2 in the accommodating space 11 can be fully utilized, and the occupation of the junction cabinet 3 on the left side of the water machine assembly 2 is reduced, so that the available space in the accommodating space 11 is still large, further improving the volume energy density of the energy storage system 100 and improving the performance of the energy storage system 100. It should be noted that the junction cabinet 3 can be a conventional junction cabinet 3 to realize the convergence of the battery packs 5 in the container, so as to facilitate the normal use of the energy storage system 100.

[0036] According to some embodiments of the present invention, referring to Figure 1 , Figure 4 and Figure 5 The energy storage system 100 further includes a fire fighting system 4, which is arranged in the accommodation space 11, the fire fighting system 4 is located below the water machine assembly 2, and the fire fighting system 4 and the junction box 3 are arranged along the thickness direction of the energy storage box 1. Figure 1 , Figure 4 and Figure 5In the example, the fire protection system 4 and the junction cabinet 3 are both located below the water machine assembly 2, and the fire protection system 4 and the junction cabinet 3 are arranged in the front-to-back direction. The fire protection system 4 can be used to detect the working conditions of the components inside the energy storage box 1. For example, when the temperature inside the energy storage box 1 is too high or an electrical component is working abnormally, the fire protection system 4 can issue an early warning and reminder, and take corresponding measures. With such an arrangement, the fire protection system 4 and the junction cabinet 3 can make full use of the space below the water machine assembly 2. The layout of the water machine assembly 2, the fire protection system 4 and the junction cabinet 3 is reasonable, which reduces the occupation of the fire protection system 4 on the left side of the water machine assembly 2, so that the available space in the accommodating space 11 is still large, thereby improving the volume energy density of the energy storage system 100.

[0037] According to some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5 , the fire fighting system 4 is located on one side of the door body (not shown) of the combiner cabinet 3 adjacent to the energy storage box 1. For example, the door body is located at the front side of the energy storage box 1, and the fire fighting system 4 is located at the front side of the combiner cabinet 3. Such a configuration is more conducive to the inspection and replacement of the fire fighting system 4, thereby facilitating the use and maintenance of the energy storage system 100, and further improving the performance of the energy storage system 100.

[0038] According to some embodiments of the present invention, referring to Figure 2 and Figure 3 , the side surface of the water machine assembly 2 facing the center of the accommodation space 11, the side surface of the combiner cabinet 3 facing the center of the accommodation space 11, and the side surface of the fire protection system 4 facing the center of the accommodation space 11 are flush. Figure 2 and Figure 3 In the example, the energy storage box 1 is set to be a rectangular parallelepiped with a hollow interior, and the water machine component 2, the fire fighting system 4 and the junction cabinet 3 are all arranged on the right side of the energy storage box 1, and the left side of the water machine component 2, the left side of the junction cabinet 3 and the left side of the fire fighting system 4 are in the same plane, and the above-mentioned same plane is perpendicular to the length direction of the container. As a result, the layout of the water machine component 2, the fire fighting system 4 and the junction cabinet 3 is reasonable, and the accommodation space 11 is reasonably utilized, which reduces the space occupied by the water machine component 2, the fire fighting system 4 and the junction cabinet 3 in the accommodation space 11, and improves the utilization rate of the accommodation space 11. In addition, the left space of the water machine component 2, the fire fighting system 4 and the junction cabinet 3 is roughly in the shape of a rectangular parallelepiped, which is conducive to arranging other components in the space on one side of the water machine component 2 facing the center of the energy storage box 1, thereby further improving the volume energy density of the energy storage system 100 and further improving the performance of the energy storage system 100.

[0039] According to some embodiments of the present invention, Figure 1-Figure 3The energy storage system 100 further includes at least one battery pack 5, which is disposed in the accommodation space 11, and the battery pack 5 is located on one side of the water machine assembly 2 facing the center of the accommodation space 11. Figure 1-Figure 3 In the example, the battery pack 5 is arranged on the left side of the water machine assembly 2. Thus, the accommodation space 11 can be fully utilized, further improving the utilization rate of the accommodation space 11. In addition, the volume of the space of the water machine assembly 2 toward the center of the energy storage box 1 is larger, which can accommodate a larger battery pack 5 to improve the energy storage performance of the energy storage system 100 and is also conducive to the installation of the battery pack 5. In addition, the structure of each component in the energy storage box 1 is compact, which is conducive to improving the energy density of the system.

[0040] According to some embodiments of the present invention, referring to Figure 1-Figure 3 There are multiple battery packs 5, which are arranged in the accommodating space 11. A first pipeline 6 and a second pipeline 7 are provided between the water machine assembly 2 and the multiple battery packs 5. The first pipeline 6 and the second pipeline 7 are located in the middle of the height direction of the energy storage box 1. The fluid flowing out of the water machine assembly 2 is suitable for flowing to the multiple battery packs 5 through the first pipeline 6, and the fluid after heat exchange with the battery pack 5 is suitable for flowing to the water machine assembly 2 through the second pipeline 7. In the description of the utility model, "multiple" means two or more.

[0041] For example, in Figure 1-Figure 3 In the example, the plurality of battery packs 5 constitute a plurality of battery pack groups 51, and the plurality of battery pack groups 51 are arranged along the length direction of the energy storage box 1, and each battery pack group 51 includes a plurality of battery pack groups 51 arranged along the height direction of the energy storage box 1 (for example, Figure 1 The first pipeline 6 is connected to the water machine assembly 2, and the first pipeline 6 extends to the left along the left-right direction. The left end of the second pipeline 7 is connected to the left end of the first pipeline 6, and the right end of the second pipeline 7 is connected to the water machine assembly 2. The fluid in the water machine assembly 2, such as cold water, can flow out from the first pipeline 6 to the multiple battery packs 5. The temperature of the fluid increases after heat exchange with the multiple battery packs 5, and the heated fluid can flow back to the water machine assembly 2 through the second pipeline 7. By arranging the first pipeline 6 and the second pipeline 7 to be located in the middle of the energy storage box 1 in the up-down direction, the first pipeline 6 and the second pipeline 7 are arranged reasonably, which is conducive to the fluid in the first pipeline 6 to flow to the multiple battery packs 5 in the accommodating space 11, and is also conducive to the fluid after heat exchange to flow back through the second pipeline 7, thereby improving the working efficiency of the water machine assembly 2 and further improving the performance of the energy storage system 100.

[0042] According to some embodiments of the present invention, Figure 1 , Figure 4 and Figure 5The energy storage box 1 has an installation space 12, which is located between the water machine assembly 2 and the combiner cabinet 3, and the installation space 12 is close to one side of the energy storage box 1 in the thickness direction. Figure 1 , Figure 4 and Figure 5 In the example, the installation space 12 is connected to the accommodating space 11, the installation space 12 is arranged at the rear side of the right end of the energy storage box 1, and the installation space 12 is located below the water machine assembly 2. In this way, the inlet pipe 24 and the outlet pipe 25 of the water machine assembly 2 can be arranged in the installation space 12, one end of the inlet pipe 24 is connected to the water machine assembly 2, and the other end of the inlet pipe 24 extends to the outside of the energy storage box 1 through the installation space 12, and one end of the outlet pipe 25 is connected to the water machine assembly 2, and the other end of the outlet pipe 25 extends to the outside of the energy storage box 1 through the installation space 12, so as to facilitate the replenishment of fluid into the water machine assembly 2 through the inlet pipe 24, or the discharge of fluid in the water machine assembly 2 through the outlet pipe 25. In addition, the position of the installation space 12 is reasonably set, and the space between the water machine assembly 2 and the junction cabinet 3 can be effectively utilized to improve the space utilization rate of the accommodating space 11.

[0043] According to some embodiments of the present invention, referring to Figure 1 The water machine assembly 2 has an air inlet 21 and an air outlet 22. The air inlet 21 is formed on one side of the water machine assembly 2 away from the center of the accommodating space 11, and the air outlet 22 is formed on the top of the water machine assembly 2. Figure 1 In the example of FIG. 1 , the air inlet 21 is formed on the right side of the water machine component 2, and the air outlet 22 is formed on the top surface of the water machine component 2. Thus, the external air can flow into the water machine component 2 from the air inlet 21, and then flow out from the top of the water machine component 2 (for example, the flow path is as follows Figure 1 The above-mentioned flow path is conducive to the air flowing through the interior of the water machine component 2, and can reduce the noise of the water machine component 2 when it is working, thereby reducing the operating noise of the energy storage system 100, for example, the noise is less than 75dBa@1m, which is more conducive to the use of the energy storage system 100. Moreover, the space on the top of the energy storage box 1 can be fully utilized, and the surrounding noise can be reduced. In addition, by setting the water machine component 2 at the upper right position in the energy storage box 1, the noise emitted by the energy storage system 100 when working, which is heard by the staff, can also be reduced, thereby improving the user experience.

[0044] Optionally, combined Figure 4 and Figure 5 The water machine assembly 2 includes a plurality of fans 23, and the inlets 231 of the plurality of fans 23 are opposite to the air inlet 21. Figure 4 and Figure 5In the example, nine fans 23 are provided on the water machine assembly 2, and the inlet 231 of each fan 23 is opposite to the air inlet 21 of the water machine assembly 2. Therefore, it is beneficial for the fan 23 to draw the air outside the energy storage box 1 into the water machine assembly 2, thereby improving the working efficiency of the water machine assembly 2 and facilitating the use of the water machine assembly 2. It should be noted that the working principle of the water machine assembly 2 is similar to the principle of air conditioning cooling or heating, and will not be described in detail here.
