[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Reference below Figure 1-Figure 5 An energy storage module 100 according to an embodiment of the first aspect of the present utility model is described.

[0038] like Figure 3 and 4 As shown, the energy storage module 100 according to the first embodiment of the utility model includes: a first battery pack 10 and a second battery pack 20 .

[0039] Specifically, the first battery pack 10 includes a first main body 11 and a first cold plate 12. The first cold plate 12 is disposed on the first main body 11 in a first direction (eg Figure 4 The second battery pack 20 includes a second main body 21 and a second cold plate 22. The second main body 21 is arranged on the other side of the first main body 11 away from the first cold plate 12 in the first direction. The first main body 11 and the second main body 21 are arranged at intervals in the first direction and form an air-cooling channel 30. The second cold plate 22 is connected to the second main body 21 and is located on the side of the second main body 21 away from the first main body 11.

[0040] During the operation of the energy storage device 10000, the first battery pack 10 and the second battery pack 20 will generate heat to increase the temperature of the first battery pack 10 and the second battery pack 20. In this embodiment, in the first direction, a first cold plate 12 is provided on one side of the first battery pack 10, and an air cooling channel 30 is provided on the other side of the first battery pack 10, a second cold plate 22 is provided on one side of the second battery, and an air cooling channel 30 is provided on the other side of the second battery pack 20. In this way, the airflow in the first cold plate 12 and the air cooling channel 30 can cool down the first battery pack 10 on both sides of the first battery pack 10 in the first direction, and the airflow in the second cold plate 22 and the air cooling channel 30 can cool down the second battery pack 20 on both sides of the first direction, thereby improving the cooling efficiency of the first battery pack 10 and the second battery pack 20, and the first battery pack 10 and the second battery pack 20 are cooled more evenly.

[0041] It is understandable to those skilled in the art that the manufacturing cost of cooling achieved by the air flow in the air cooling channel 30 is relatively low. By providing an air cooling channel 30 between the first battery pack 10 and the second battery pack 20 to cool the first battery pack 10 and the second battery pack 20, the production cost of the energy storage device 10000 can be reduced.

[0042] In addition, the air cooling channel 30 between the first battery pack 10 and the second battery pack 20 can provide a fulcrum and operating space. When the energy storage equipment needs to be repaired, the operator can more easily disassemble the first battery pack 10 and the second battery pack 20, thereby facilitating the maintenance of the energy storage device 10000.

[0043] The energy storage module 100 according to the first embodiment of the utility model can improve the cooling efficiency and cooling uniformity of the first battery pack 10 and the second battery pack 20, reduce production costs, and reduce the difficulty of maintenance of the energy storage device 10000.

[0044] In some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the air cooling channel 30 is along the second direction (eg Figure 2 The second direction extends in the front-to-back direction shown in the figure, and the second direction is perpendicular to the first direction. The energy storage module 100 also includes: an airflow driving assembly 40, which is used to drive the airflow in the air-cooling channel 30 to flow from one end to the other end in the second direction.

[0045] During the operation of the energy storage module 100, the airflow driving assembly 40 drives the airflow to flow in the air cooling channel 30. In the process of the airflow flowing from one end to the other end of the air cooling channel 30 in the second direction, the airflow will take away part of the heat on the first battery pack 10 and the second battery pack 20, thereby achieving cooling of the first battery pack 10 and the second battery pack 20.

[0046] In some embodiments of the present invention, Figure 3 As shown, the airflow drive assembly 40 includes a plurality of drive fans, for example, the drive fans may be two, four, seven or ten, the drive fans are arranged on one side of the air cooling channel 30 in the second direction, and the plurality of drive fans are arranged along the third direction (for example Figure 3 The first and second directions are arranged in sequence (in the left and right directions shown in FIG), and the third direction is perpendicular to the first and second directions. The driving fan can generate airflow in the air cooling channel 30 during rotation, thereby realizing the airflow driving function of the airflow driving assembly 40, and the fan has low cost and is easy to arrange, thereby further reducing the production cost and reducing the difficulty of product design and production.

[0047] In some embodiments of the present invention, Figure 4 As shown, the energy storage module 100 further includes: an air duct plate 50, which is connected between the first body 11 and the second body 21. The number of the air duct plates 50 is multiple, for example, the air duct plates 50 may be two, five, ten or fifteen, and the multiple air duct plates 50 extend along the second direction and are arranged at intervals in the third direction. The first direction, the second direction and the third direction are perpendicular to each other, and the air cooling channel 30 is formed between adjacent air duct plates 50. By providing the air duct plates 50, the air cooling channel 30 can be defined. When the air flow flows between the first battery pack 10 and the second battery pack 20, the air duct plates 50 can limit the flow path of the air flow, so that the air flow contacts the first battery pack 10 and the second battery pack 20 during the flow, thereby realizing the cooling of the first battery pack 10 and the second battery pack 20. By providing multiple air duct plates 50, the air flow can be more evenly distributed in the air cooling channel 30, thereby further improving the uniformity of cooling the first battery pack 10 and the second battery pack 20.

[0048] In some embodiments of the present invention, Figure 4 and Figure 5As shown, the air duct plate 50 includes: a first plate 51 and a second plate 52, the first plate 51 is connected to the first body 11 and extends along the first direction toward the second body 21, the second plate 52 is connected to the second body 21 and extends along the first direction toward the first body 11, wherein the number of the first plates 51 is multiple, for example, the first plates 51 can be two, five, ten or fifteen, and the multiple first plates 51 are arranged at intervals along the third direction, the number of the second plates 52 corresponds to the number of the first plates 51 one by one, and in the first direction, the end of the first plate 51 away from the first body 11 is connected to the end of the second plate 52 away from the second body 21.

[0049] During the product design process, the first plate 51 can be set on the cover plate of the first battery pack 10 on the side close to the second battery pack 20, and the second plate 52 can be set on the cover plate of the second battery pack 20 on the side close to the first battery pack 10, and the heights of the first plate 51 and the second plate 52 can be set to be the same. In this way, the same type of cover plate can be used on the opposite side surfaces of the first battery pack 10 and the second battery pack 20, thereby reducing the number of molds in the production process and further reducing production costs.

[0050] In some embodiments of the present invention, Figure 4 As shown, the energy storage module 100 further includes two seals 60, which are respectively arranged on both sides of the plurality of air duct plates 50 in the third direction, and the two seals 60 are both sealed and connected between the first body 11 and the second body 21, and the seals 60 and the adjacent air duct plates 50 are arranged at intervals in the third direction to form an air cooling channel 30 between the seals 60 and the air duct plates 50. By providing the seals 60, the seals 60 can seal the air cooling channel 30 at both ends of the air cooling channel 30 in the third direction, and the air flow will not leak from both ends of the air cooling channel 30 in the third direction during the process of flowing from one end to the other end of the air cooling channel 30 in the second direction, thereby improving the cooling effect of the air flow on the first battery pack 10 and the second battery pack 20. In addition, the seals 60 can provide support between the first battery pack 10 and the second battery pack 20, thereby improving the structural stability of the energy storage module 100.

In the process of product design, by adjusting the number of energy storage groups 1000 in the energy storage device 10000 and the number of energy storage modules 100 in the energy storage group 1000, the energy storage capacity of the energy storage device 10000 may be adjusted, thereby meeting more product design requirements and reducing the difficulty of product design.

It can be understood that the cooling efficiency of the heat exchanger 2000 is higher. During the operation of the energy storage device 10000, the airflow can first flow through the heat exchanger 2000, and the heat exchanger 2000 cools the airflow, and then the cooled airflow passes through the air cooling channel 30 to cool the first battery pack 10 and the second battery pack 20, thereby further improving the cooling effect of the airflow on the energy storage device 10000.

[0056] During the operation of the energy storage device 10000, different cooling modes can be set according to the working state of the energy storage device 10000. For example, when the temperature of the energy storage device 10000 is low, the first battery pack 10 and the second battery pack 20 can be cooled by the airflow in the first cold plate 12, the second cold plate 22 and the air cooling channel 30; when the temperature of the energy storage device 10000 is high, the heat exchanger 2000 can be operated, and the airflow after the temperature of the heat exchanger 2000 is cooled in the first cold plate 12, the second cold plate 22 and the air cooling channel 30 cools the first battery pack 10 and the second battery pack 20, thereby increasing the cooling rate.

By supporting the first battery pack 10 and the second battery pack 20 by the first bracket 4100 and the second bracket 4200, the first battery pack 10 and the second battery pack 20 can be easily disassembled, thereby further improving the convenience of maintenance of the energy storage device 10000.

[0058] In some embodiments of the utility model, the energy storage device 10000 also includes: a water machine and a compressor, the water machine is connected to the first cold plate 12 and the second cold plate 22, and the compressor is connected to the heat exchanger 2000. During the operation of the energy storage device 10000, the water machine can drive the coolant to flow in the first cold plate 12 and the second cold plate 22. During the flow of the coolant, part of the heat of the first battery pack 10 and the second battery pack 20 can be taken away, thereby cooling the first battery pack 10 and the second battery pack 20. After the compressor compresses the heat exchange medium, the heat exchange medium flows into the heat exchanger 2000, and the heat exchange medium exchanges heat with the airflow in the heat exchanger 2000, thereby cooling the airflow.
