Description

Technical Field

[0001] This application relates to the field of energy storage container technology, specifically to an energy storage container, and further to an energy storage system comprising the energy storage container. Background Technology

[0002] With the rapid development of the energy storage industry in recent years, energy storage systems have been gradually applied to power plant regulation, peak shaving and valley filling in industrial parks, and microgrids. Large-scale outdoor energy storage typically consists of hundreds or thousands of energy storage batteries connected in series and parallel to form battery clusters, which are then integrated into a container. Since the charging and discharging process of the energy storage batteries inside the container generates a large amount of heat, and the temperature of the energy storage batteries has a significant impact on battery life and system safety, thermal management of energy storage containers is particularly important.

[0003] Some existing energy storage containers have energy storage converters installed inside. Generally, the energy storage converter and battery units are cooled together. Since the actual heat dissipation of the energy storage converter is large, a lot of electrical energy is consumed during the heat dissipation process, resulting in high overall temperature control energy consumption of the container. In addition, existing energy storage containers generally place the temperature control system on the outside of the container, resulting in an uneven outer surface. In actual transportation, the gap between adjacent containers is large, leading to higher transportation costs and making it difficult to meet the low-cost transportation requirements of energy storage containers.

[0013] In addition to one or more of the above, or as an alternative, in another embodiment, the barrier member includes a first partition and a second partition connected at one end and abutting against two adjacent inner walls at one corner of the housing, wherein the side of the first partition away from the second chamber forms the transverse zone between the side of the first partition away from the second chamber and two adjacent inner walls at another corner of the first chamber, and the remaining space inside the first chamber forms the longitudinal zone.

[0014] In addition to one or more of the above, or as an alternative, in another embodiment, the energy storage container further includes: Fire suppression units and sensing units are configured to be located within the enclosure, and / or The communication control cabinet is located inside the second chamber and next to the battery module.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By dividing the container into a first chamber and a second chamber where airflow is not interconnected, it is convenient to place the battery module and the energy storage converter separately, thereby achieving independent heat dissipation for the battery module and the energy storage converter. This reduces the increased energy consumption caused by the large heat dissipation of the energy storage converter, and thus helps to reduce the overall temperature control energy consumption of the container. The air duct and air conditioning module of the temperature control unit can meet the effective heat dissipation of the internal battery module and ensure its normal operation. The air guide unit can accelerate the air exchange between the air around the energy storage converter located in the second chamber and the outside airflow, further improving the heat dissipation effect of the energy storage converter. In addition, the air conditioning module of the temperature control unit is embedded in the inner wall of the container in the first chamber, thereby reducing the gap between adjacent containers during transportation. While meeting the heat dissipation effect of the energy storage converter, it reduces the temperature control energy consumption and transportation cost of the container, and can meet the overall heat dissipation requirements of the container.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0026] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0027] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0028] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] In existing technologies, energy storage containers typically place temperature control systems (such as air conditioners) on the outside of the container, resulting in an uneven outer surface. This leads to larger gaps between adjacent containers during actual transportation, resulting in higher transportation costs and making it difficult to meet the low-cost transportation requirements of energy storage containers. In addition, the energy storage converter and battery cluster are cooled together. Since the energy storage converter generates a lot of heat, the actual heat dissipation energy consumption is high, resulting in higher operating costs.

[0030] Figure 1 This is a perspective view of an energy storage container according to the present application. The energy storage container can be used in an energy storage system and includes: a housing 1 configured to have at least two non-communicating chambers, a first chamber 11 and a second chamber 12, respectively housed in the first chamber 11 and the second chamber 12; an air conditioning module 41 configured to include at least an air conditioning unit embedded in the inner wall of the housing 1 within the first chamber 11 and communicating with the outside airflow; a temperature control unit 4 with an air duct 42 disposed inside the first chamber 11 and communicating with the air conditioning module 41; and an air guide unit 5 constructed in the second chamber 12 and configured to accelerate the airflow exchange between the second chamber 12 and the outside.

[0031] Under this arrangement, refer to Figures 1-5 The energy storage container described in this article divides the container body 1 into a first chamber 11 and a second chamber 12, which are not interconnected by airflow. This facilitates the separate placement of the battery module 2 and the energy storage converter 3, thereby enabling independent heat dissipation for the battery module 2 and the energy storage converter 3. This reduces the increased energy consumption caused by the large heat dissipation of the energy storage converter 3, and thus helps to reduce the overall temperature control energy consumption of the container. The air duct 42 and air conditioning module 41 of the temperature control unit 4 can effectively dissipate heat from the internal battery module 2, ensuring its normal operation. The air guide unit 5 can... To accelerate the air exchange between the energy storage converter 3 located inside the second chamber 12 and the outside airflow, the heat dissipation effect of the energy storage converter 3 is further improved. In addition, the air conditioning module 41 of the temperature control unit 4 is embedded on the inner wall of the box 1 inside the first chamber 11, which can effectively avoid the unevenness of the outer surface of the box 1 caused by its external placement, thereby reducing the gap between adjacent containers during transportation. While meeting the heat dissipation effect of the energy storage converter 3, it reduces the temperature control energy consumption and transportation cost of the container, and can meet the overall heat dissipation requirements of the container.

[0032] It should be noted that battery module 2 is generally a battery cluster, which is a battery system formed by connecting multiple battery packs together in series, parallel or series-parallel connection. In energy storage containers, multiple battery clusters are usually placed to expand their capacity.

[0033] In actual operation, the Power Conversion System (PCS) is an important component of the energy storage system. It can be connected between the energy storage device and the power grid or load. It is mainly responsible for realizing the bidirectional AC / DC conversion of electrical energy in the energy storage system to control the charging and discharging process of the energy storage battery pack.

[0034] The following will illustrate further specific implementations or refinements of the board enclosure assembly through exemplary description, in order to further improve it or for other improvement considerations.

[0035] In one embodiment, reference is made to... Figure 3 and Figure 4 The air conditioning module 41 has an air inlet on one side embedded in the inner wall of the housing 1 and is connected to the outside airflow. The air outlet on the other side of the air conditioning module 41 is separated from the battery module 2 inside the first chamber 11 by a certain distance.

[0036] It can be seen that by embedding the air conditioning module 41 into the inner wall of the container 1 and connecting the air inlet with the external airflow, the air conditioning module 41 can directly obtain air from the outside. Moreover, the built-in installation method can avoid the protrusion of the outer surface of the container 1, which makes it easier for two adjacent energy storage containers to be placed close together, effectively reducing the gap during transportation, thereby increasing the transportation efficiency per unit volume and reducing the overall transportation cost.

[0037] In this arrangement, the air conditioning module 41 can be connected to the air duct 42 to deliver cold air to different battery module 2 locations, thereby achieving effective cooling of the battery module 2.

[0038] For example, the air conditioning module 41 mentioned above can be an outdoor air conditioning unit, which has built-in devices such as a condenser, evaporator, and expansion valve to achieve temperature regulation inside the first chamber 11, thereby achieving temperature control of the battery module 2 and providing a temperature basis for its normal operation. The specific type, model and size can be selected according to actual production needs, and this embodiment does not make specific limitations here.

[0039] Specifically, refer to Figure 3 and Figure 6The air duct 42 is constructed between the battery module 2 and the inner top wall of the housing 1, and the bottom of the air duct 42 is provided with a plurality of air guides 421 that are opposite to the gap between two adjacent sets of battery modules 2.

[0040] It is easy to see that by constructing the air duct 42 between the battery module 2 and the inner top wall of the housing 1, it is convenient to deliver cold air to different locations. In addition, the air guide 421 at the bottom of the air duct 42 allows the cold air output by the air conditioning module 41 to be evenly distributed around the battery module 2, avoiding local overheating. The gap between the air guide 421 and the two adjacent battery modules 2 further enhances the airflow around the battery module 2 and improves the heat dissipation effect of the battery module 2.

[0041] It should be noted that the air vents 421 of the air duct 42 can also be arranged in other ways, such as corresponding to the gap between the battery module 2 and the housing 1. The shape of the air vents 421 can be circular, square or triangular, as long as it can effectively guide air and dissipate heat. This embodiment does not make specific limitations here.

[0042] In actual operation, this embodiment should be referred to Figures 2-4 ,as well as Figure 7 The air guiding unit 5 includes: an air inlet louver 51 and an air outlet louver 52 arranged sequentially on the two adjacent outer side walls of the housing 1 at the position of the second chamber 12 and configured to control the airflow between the second chamber 12 and the outside airflow or to block the airflow; and an exhaust fan 53 fitted to the inner side of the exhaust louver 52 and configured to accelerate the airflow exchange between the second chamber 12 and the outside airflow.

[0043] It can be seen that the air inlet louvers 51 and exhaust louvers 52 can flexibly control the airflow between the second chamber 12 and the outside, thus facilitating manual adjustment of the airflow volume according to actual heat dissipation needs; the exhaust fan 53 further accelerates the airflow exchange speed between the second chamber 12 and the outside, facilitating the timely discharge of heat generated during the operation of the energy storage converter 3 from the second chamber 12, thereby effectively ensuring the heat dissipation effect of the energy storage converter 3.

[0044] For example, the air inlet louvers 51 and exhaust louvers 52 can also be configured as air inlet and exhaust windows with adjustable size, and the exhaust fan 53 can also be configured as a cooling fan with cooling function as needed. Of course, it can also be other types of cooling equipment. The focus of this embodiment is to separate the heat dissipation of the energy storage converter 3 and the battery module 2. The specific implementation method can be selected as needed. This embodiment does not make specific limitations here.

[0045] It should be noted that during maritime transport, using 10HQ standard-sized containers not only meets customs transport requirements, but also allows two 10HQ standard-sized containers to be combined to form a 20HQ energy storage container. Therefore, the arrangement of the battery modules 2 inside the 10HQ standard-sized container is crucial to improving the capacity of the energy storage container while ensuring transport requirements. To this end, this embodiment improves the arrangement of the battery modules 2 inside the container.

[0046] In one embodiment, reference is made to... Figure 3 and Figure 4 The first chamber 11 includes at least a horizontal row area 111 and a vertical row area 112. At least one set of battery modules 2 are arranged inside the horizontal row area 111 along a first direction, and at least one set of battery modules 2 are arranged inside the vertical row area 112 along a second direction. The first direction and the second direction are perpendicular to each other.

[0047] It can be seen that by setting the first chamber 11 into a horizontal row area 111 and a vertical row area 112, it is convenient to install and place the battery modules 2 along a predetermined direction. While ensuring heat dissipation, this makes the layout of the battery modules 2 inside the container 1 more reasonable, the space utilization rate higher, and it can accommodate more battery modules 2, thereby helping to increase the capacity of the energy storage container. Specifically, in this embodiment, the container 1 is configured as a 10HQ standard container, and its lengths along the first direction, the second direction, and the height direction are 2438 mm, 2991 mm, and 2896 mm, respectively.

[0048] It should be noted that by setting the above-mentioned container 1 as a 10HQ standard container, the transportation requirements can be effectively guaranteed. At the same time, the distribution of the horizontal row area 111 and the vertical row area 112 has been found through multiple tests to be able to further optimize the layout of the battery module 2 while ensuring that the energy storage converter 3 and the battery module 2 are cooled separately, thereby effectively increasing the capacity of the 10HQ standard container.

[0049] In actual operation, this embodiment should be referred to Figure 4 The horizontal row area 111 has two sets of battery modules 2 arranged sequentially along the first direction, and the vertical row area 112 has four sets of battery modules 2 arranged sequentially along the second direction.

[0050] It can be seen that by limiting the number of battery modules 2 in the horizontal row 111 and the vertical row 112, two sets of battery modules 2 are set in the horizontal row 111 and four sets of battery modules 2 are set in the vertical row 112. Through this specific arrangement and optimized design, it is easy to reasonably arrange the number and position of battery modules 2, and the energy storage capacity of the energy storage container can be increased while achieving good heat dissipation.

[0051] In another embodiment, reference is made to... Figure 3 and Figure 4 The temperature control unit 4 is configured as two, one of which corresponds to the battery module 2 in the horizontal row area 111, and the other of which corresponds to the battery module 2 in the vertical row area 112.

[0052] It is easy to see that by setting temperature control units 4 in the horizontal row area 111 and the vertical row area 112 respectively, independent temperature control can be performed on the battery modules 2 in different areas, thereby improving the heat dissipation effect of the battery modules 2 in different areas.

[0053] For example, the number of battery modules 2 inside the horizontal and vertical rows 111 can be further selected and optimized according to the size of the container. At the same time, the number and distribution of the internal temperature control units 4 can also be further adjusted, thereby increasing the capacity of the energy storage container while ensuring good heat dissipation. This embodiment does not make specific limitations here.

[0054] In one embodiment, reference is made to... Figures 3-5 The container also includes a barrier member 6, the two ends of which abut against the inner walls of one of the corners of the container body 1 and form the second chamber 12 therewith, and the remaining space inside the container body 1 forms the first chamber 11.

[0055] It is easy to see that the setting of the barrier component 6 can divide the internal space of the housing 1 into the first chamber 11 and the second chamber 12, thereby facilitating the effective isolation of the battery module 2 and the energy storage converter 3, and thus facilitating the separate heat dissipation treatment of the two, and effectively avoiding the transfer of heat between the first chamber 11 and the second chamber 12, thereby helping to improve the heat dissipation effect.

[0056] Specifically, refer to Figure 5 The barrier member 6 includes a first partition 61 and a second partition 62 connected at one end and respectively abutting against two adjacent inner walls at one corner of the box 1. The side of the first partition 61 facing away from the second chamber 12 forms the horizontal area 111 between the side of the first partition 61 and two adjacent inner walls at another corner inside the first chamber 11. The remaining space inside the first chamber 11 forms the vertical area 112.

[0057] It can be seen that the barrier component 6 formed by splicing the first partition 61 and the second partition 62 can effectively divide the first chamber 11 and the second chamber 12. It also facilitates the division of the first chamber 11 into a horizontal area 111 and a vertical area 112, which is convenient for the subsequent installation of the battery module 2. In addition, it also facilitates the design and layout of the air duct 42. At the same time, this structure is simple and easy to implement, which can reduce the manufacturing cost of the energy storage container and has strong practicality.

[0058] For example, the first partition 61 and the second partition 62 of the above-mentioned barrier member 6 can be vertically distributed, with a 90° angle between them. The first partition 61 and the second partition 62 are effectively isolated from the airflow of the first chamber 11 and the second chamber 12 by a sealing element (such as a sealing gasket) between them and the inner wall of the box 1.

[0059] Furthermore, the angle between the two chambers can be set to 60 degrees, 75 degrees, or 100 degrees as needed. Of course, it can also be set as a stretchable and deformable structural component, as long as it can effectively separate the first chamber 11 and the second chamber 12. This embodiment does not make specific limitations here.

[0060] In another embodiment, reference is made to... Figure 4 and Figure 9 The energy storage container also includes: a fire-fighting unit 7 and a sensing unit 8 configured to be located in the container body 1, and a communication control cabinet 9 located inside the second chamber 12 and next to the battery module 2.

[0061] It can be seen that by setting up fire-fighting unit 7 and sensing unit 8, the safety of the energy storage container can be effectively improved. Fire-fighting unit 7 can extinguish fires in time when they occur inside the container, preventing the spread of fire; sensing unit 8 can monitor the temperature and smoke inside the container 1 in real time, detect abnormalities in time and issue alarms; by setting up communication control cabinet 9 inside the container 1, it is convenient to centrally manage and monitor the energy storage system, and effective management of the energy storage container can be achieved.

[0062] Furthermore, the fire unit 7 includes at least: a fire control panel 71 located inside the housing 1, and fire intake louvers 72, fire exhaust louvers 73, fire emergency stop button 74, and system emergency stop button 75 located on the outer wall of the housing 1.

[0063] It is easy to see that the fire control panel 71 can centrally manage and control the fire protection system, improving fire extinguishing efficiency and reliability; the fire air intake louvers 72 and fire exhaust louvers 73 can effectively control the air entering and leaving the container 1, improving fire extinguishing efficiency; the fire emergency stop button 74 and the system emergency stop button 75 can quickly cut off the power and stop the system operation in an emergency, ensuring the safe operation of the energy storage container.

[0064] Furthermore, the sensing unit 8 includes at least a temperature sensor and a smoke sensor located inside the housing 1.

[0065] It is known that by using temperature sensors and smoke sensors, early fire warning functions can be realized. Once abnormal temperature or smoke signals are detected, an alarm can be issued immediately, which can promptly remind relevant personnel to take measures, thereby achieving early detection and timely handling of fires.

[0066] In another embodiment, reference is made to... Figure 4 The four sides of the container 1 are configured with double doors 13 for controlling the opening or closing of the container 1. The design of the four double doors 13 being fully open facilitates the maintenance of the internal equipment of the energy storage container during later use.

[0067] This embodiment also proposes an energy storage system, including the energy storage container described above.

[0068] It can be seen that by applying the above-mentioned energy storage container to the energy storage system, and placing the battery module 2 and the energy storage converter 3 respectively, the battery module 2 and the energy storage converter 3 can be cooled independently, reducing the energy consumption caused by the large heat dissipation of the energy storage converter 3, and thus helping to reduce the overall temperature control energy consumption of the container. The setting of the air duct 42 and the air conditioning module 41 of the temperature control unit 4 can meet the effective heat dissipation of the internal battery module 2 and ensure its normal operation. The air guide unit 5 can accelerate the air exchange between the air around the energy storage converter 3 located in the second chamber 12 and the outside airflow, further improving the heat dissipation effect of the energy storage converter 3.

[0069] Furthermore, in actual operation, the air conditioning module 41 of the temperature control unit 4 is embedded in the inner wall of the housing 1 within the first chamber 11. Most of its volume is located inside the housing 1, with only a small portion of the air inlet and outlet surfaces exposed outside the housing. This effectively avoids the unevenness of the outer surface of the housing 1 caused by its external placement, reducing the gap between adjacent containers during transportation. While meeting the heat dissipation requirements of the energy storage converter 3, it also reduces the temperature control energy consumption and transportation costs of the container, thus satisfying the overall heat dissipation needs of the container. Through reasonable layout, an integrated AC / DC energy storage container solution can be achieved.

[0070] The above examples primarily illustrate the energy storage container and the energy storage system including the energy storage container of this application. Although only some embodiments of this application have been described, those skilled in the art should understand that this application can be implemented in many other forms without departing from its spirit and scope. Therefore, the examples and embodiments shown are considered illustrative rather than restrictive, and this application may cover various modifications and substitutions without departing from the spirit and scope of the technical solution of this application.
