Description

Technical Field

[0001] This application relates to the field of energy storage cabinet technology, and in particular to an energy storage cabinet. Background Technology

[0002] As the global energy structure accelerates its transition towards cleaner and lower-carbon energy, the installed capacity of renewable energy sources such as solar and wind power continues to climb. However, renewable energy generation is characterized by significant intermittency and volatility. For example, solar power relies on sunlight, and wind power is constrained by weather conditions, making stable grid connection difficult and severely limiting the efficiency of renewable energy utilization. Energy storage units, as core equipment for solving this problem, can store electrical energy during periods of energy surplus and release it during periods of energy shortage, effectively smoothing the power generation curve and increasing the proportion of renewable energy in the energy structure, thus becoming a crucial link in promoting energy transformation.

[0003] In related technologies, an unreasonable structural design of the energy storage cabinet not only affects the working stability of the components installed inside the cabinet, but also hinders the overall stability and ease of use of the energy storage cabinet. Utility Model Content

[0004] Therefore, it is necessary to provide an energy storage cabinet to address the above-mentioned problems.

Detailed Implementation

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] See Figures 1 to 5As shown, the energy storage cabinet 100 according to this application includes a cabinet body 1, a first partition 11, a first cabinet door 21, a second cabinet door 22, a third cabinet door 31, and a fourth cabinet door 32. A receiving compartment 10 is provided inside the cabinet body 1. The first partition 11 is disposed within the receiving compartment 10 and is capable of dividing the receiving compartment 10 into a spatially independent battery compartment 101 and an electrical compartment 102. In other words, the first partition 11 spatially isolates the battery compartment 101 and the electrical compartment 102, preventing heat transfer between them.

[0047] The battery compartment 101 and the electrical compartment 102 are arranged along the vertical direction, and the cabinet 1, the battery compartment 101, and the electrical compartment 102 are arranged along the vertical central axis (i.e., the central axis of the energy storage cabinet 100, such as...). Figure 4 The axis X shown in the diagram coincides with the battery module 5. Thus, when the battery module 5 is arranged in the battery compartment 101 and the electrical components are arranged in the electrical compartment 102, the problem of lateral center of gravity shift caused by the traditional left-right arrangement of energy storage cabinets is effectively avoided. Furthermore, the battery compartment 101 is located above the electrical compartment 102. In other words, the electrical compartment 102 is located at the bottom of the energy storage cabinet 100, resulting in a lower relative height of the electrical compartment 102 within the energy storage cabinet 100, facilitating maintenance of the electrical components placed within the electrical compartment 102 by operators.

[0048] In addition, the first cabinet door 21 and the third cabinet door 31 are located on the front side of the cabinet body 1, and the second cabinet door 22 and the fourth cabinet door 32 are located on the rear side of the cabinet body 1. The first cabinet door 21 and the second cabinet door 22 are used to open and close the battery compartment 101, and the third cabinet door 31 and the fourth cabinet door 32 are used to open and close the electrical compartment 102. Specifically, when the first cabinet door 21 is open, the front side of the battery compartment 101 is open; when the second cabinet door 22 is open, the rear side of the battery compartment 101 is open; when the third cabinet door 31 is open, the front side of the electrical compartment 102 is open; and when the fourth cabinet door 32 is open, the rear side of the electrical compartment 102 is open. Thus, both the battery compartment 101 and the electrical compartment 102 can be opened in both directions (front and rear).

[0049] Because the battery compartment 101 has a bidirectional opening and closing design, when one opening of the battery compartment 101 (such as the front opening) is used to install the battery modules 5, the other opening (such as the rear opening) is used by the operator to connect multiple battery modules 5 using wiring harnesses. This design allows the operator to first install the battery modules 5 into the battery compartment 101, and after the battery modules 5 are assembled and fixed in the preset position, the operator can connect each battery module 5 from the other side using wiring harnesses. Compared to connecting each battery module 5 with wiring harnesses first and then installing the battery modules 5 into the battery compartment 101, this not only improves the operator's assembly efficiency, but also allows the wiring harnesses arranged in the battery compartment 101 to be concentrated on the rear side of the battery compartment 101. This not only helps to shorten the required length of the wiring harnesses and reduce costs, but also makes it easier for the operator to perform maintenance during the later use of the energy storage cabinet 100 (for example, if the operator needs to check the wiring status of each battery module 5, the operator only needs to open the second cabinet door 22). Similarly, the electrical compartment 102, which also has a two-way opening and closing design, can achieve the same effect as the two-way opening and closing design of the battery compartment 101.

[0050] In summary, according to the energy storage cabinet 100 of this application, the cabinet body 1 is divided into an independent battery compartment 101 and an electrical compartment 102 by the first partition 11, which achieves physical thermal insulation and avoids the battery heat from affecting the temperature rise of the electrical compartment 102, thus ensuring the working stability of the electrical components. The battery compartment 101 and the electrical compartment 102 are arranged vertically, and the cabinet body 1, the battery compartment 101 and the electrical compartment 102 are aligned along the central axis of the vertical direction, eliminating the problem of lateral center of gravity shift caused by the left-right arrangement of traditional energy storage cabinets, and improving the stability of transportation and use. The cabinet door adopts a zoned independent opening and closing and bidirectional opening design to facilitate maintenance and assembly operations.

[0051] In some embodiments of this application, the energy storage cabinet 100 further includes a heat insulation component made of a heat insulation material (such as ceramic fiber, aerogel, or polyurethane foam). The first partition 11 has a hollow space within it, and the heat insulation component is disposed within this hollow space. In other words, the first partition 11 forms a shell structure enclosing the heat insulation component, completely sealing it within its internal cavity (i.e., the hollow space). Thus, the heat insulation component and the first partition 11 constitute a composite heat insulation barrier. Furthermore, since the first partition 11 can directly withstand the high-temperature environment on the battery compartment 101 side and possesses inherent fire-resistant properties, the heat insulation component located in the hollow space does not require additional fire-resistant properties, thereby reducing costs. Additionally, the heat insulation component is disposed inside the first partition 11, preventing wear and aging caused by exposure.

[0052] See Figures 1 to 4As shown, in some embodiments of this application, the first cabinet door 21 includes an even number of first sub-cabinet doors 210 (e.g., the first cabinet door 21 includes two first sub-cabinet doors 210). The even number of first sub-cabinet doors 210 are symmetrically arranged relative to the battery compartment 101 along the vertical central axis, and each first sub-cabinet door 20 can rotate around the vertical direction to open or close the battery compartment 101. In other words, the first cabinet door 21 adopts a width-direction split design, which significantly reduces the size of a single door panel (i.e., the first sub-cabinet door 210). This avoids the problem of uncontrolled flatness caused by an excessively large door panel, while reducing the reliance on reinforcing ribs for the door panel, reducing the overall weight, and fundamentally eliminating the risk of long-term load-bearing deformation of the door hinge and corner chipping of the door panel.

[0053] See Figures 1 to 5 As shown, in some embodiments of this application, the second cabinet door 22 includes an even number of second sub-cabinet doors 220 (e.g., the second cabinet door 22 includes two second sub-cabinet doors 220). The even number of second sub-cabinet doors 220 are symmetrically arranged relative to the battery compartment 101 along the vertical central axis, and each first sub-cabinet door 20 can rotate around the vertical direction to open or close the battery compartment 101. In other words, the second cabinet door 22 adopts a width-direction split design, which significantly reduces the size of a single door panel (i.e., the second sub-cabinet door 220). This avoids the problem of uncontrolled flatness caused by an excessively large door panel, while reducing the reliance on reinforcing ribs for the door panel, reducing the overall weight, and fundamentally eliminating the risk of long-term load-bearing deformation of the door hinge and corner chipping of the door panel.

[0054] See Figure 4 and Figure 5 As shown, in some embodiments of this application, a second partition 12 is provided inside the battery compartment 101. The second partition 12 is provided inside the battery compartment 101 to divide the battery compartment 101 into two independent sub-battery compartments 1010. The two sub-battery compartments 1010 are arranged sequentially in the width direction and are symmetrically arranged with respect to the central axis of the battery compartment 101 in the vertical direction.

[0055] The energy storage cabinet also includes two sets of battery modules, which are respectively housed in two sub-battery compartments 1010. Since these two sub-battery compartments 1010 are symmetrically arranged relative to the central axis of the battery compartment 101 in the vertical direction, the symmetrical arrangement of the two sets of battery modules within the two sub-battery compartments 101 relative to the central axis of the battery compartment 101 helps the center of gravity of the energy storage cabinet 100 return to its geometric center (i.e., the central axis of the energy storage cabinet 100), thus improving the stability of the energy storage cabinet 100. It should be understood that each set of battery modules includes multiple battery modules 5 arranged in a vertical row. Alternatively, it can be understood that multiple battery modules 5 are arranged as a set of battery modules in one sub-battery compartment 1010.

[0056] It should be further explained that a second partition 12 is provided within the battery compartment 101 to divide the battery compartment 101 into multiple sub-battery compartments 1010, which are arranged side-by-side in the width direction. This ensures that the battery modules housed within the multiple sub-battery compartments 1010 are also arranged side-by-side. Thus, the battery modules 5 in adjacent battery modules are aligned one-to-one in the height direction, which to some extent makes the thermal environment of adjacent sub-battery compartments 1010 more consistent, thereby improving the overall heat dissipation efficiency and operational stability of the battery modules 5. Therefore, the addition of the second partition 12 within the battery compartment 101 to form side-by-side sub-battery compartments 1010 in the width direction helps to enhance the uniformity of thermal management and suppress temperature differences between adjacent battery modules.

[0057] See Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments of this application, the energy storage cabinet 100 may further include an even number of temperature-controlled air conditioners 41, which are mounted on the first cabinet door 21 and / or the second cabinet door 22, and are arranged symmetrically with respect to the cabinet body 1 along the vertical central axis. The temperature-controlled air conditioners 41 are configured to regulate the temperature inside the battery compartment 101. The temperature-controlled air conditioners 41 can monitor and regulate the ambient temperature of the battery compartment 101 in real time to avoid negative impacts on battery performance caused by excessively high or low temperatures. For example, in high-temperature environments, the temperature-controlled air conditioners 41 operate to prevent performance degradation or safety risks caused by overheating of the battery module 5. Thus, through the active intervention of the battery compartment 101, the working efficiency and service life of the battery module 5 are significantly improved, while reducing the failure rate caused by temperature fluctuations. In addition, due to the physical thermal insulation between the battery compartment 101 and the electrical compartment 102, and the fact that the temperature-controlled air conditioners 41 focus on temperature optimization inside the battery compartment 101, the combination of the two forms a dual temperature management mechanism, ensuring the stable operation of the battery module 5.

[0058] For example, see Figure 3 and Figure 5 As shown in some embodiments of this application, the energy storage cabinet 100 is equipped with two temperature-controlled air conditioners 41. The two temperature-controlled air conditioners 41 are respectively located on the two second sub-cabinet doors 220 of the second cabinet door 22, and each temperature-controlled air conditioner 41 is located in a sub-battery compartment 1010, so that each temperature-controlled air conditioner 41 is used to regulate the temperature of each sub-battery compartment 1010. This not only enables each temperature-controlled air conditioner 41 to independently regulate the temperature of each sub-battery compartment 1010, but also, since the two temperature-controlled air conditioners 41 are symmetrically arranged with respect to the cabinet body 1 along the vertical central axis, it is beneficial for the center of gravity of the energy storage cabinet 100 to return to the geometric center (i.e., the central axis of the energy storage cabinet 100), thereby improving the stability of the energy storage cabinet 100.

[0059] See Figure 1 , Figure 3 and Figure 5 As shown in some embodiments of this application, the energy storage cabinet 100 may further include a temperature-controlled fan 42, and the third cabinet door 31 and / or the fourth cabinet door 32 are provided with heat dissipation ducts 30. The temperature-controlled fan 42 is disposed on the third cabinet door 31 and / or the fourth cabinet door 32, and the temperature-controlled fan 42 is configured to drive airflow through the heat dissipation ducts 30 from the electrical compartment 102 to the external environment. The temperature-controlled fan 42 is used to cool the electrical compartment 102, so that the temperature inside the electrical compartment 102 is maintained at a suitable temperature.

[0060] See Figure 5 As shown in some embodiments of this application, the electrical components housed within the energy storage cabinet 100 include an inverter 6, which is disposed in the electrical compartment 102. The inverter 6 is equipped with an exhaust fan 61, which is configured to dissipate heat from the inverter 6. By cooperating with the exhaust fan 61 of the inverter 6 and the temperature-controlled fan 42 mounted on the third cabinet door 31 and / or the fourth cabinet door 32, a tiered heat dissipation system is formed. The exhaust fan 61 serves as the first stage of heat dissipation, efficiently cooling the inverter 6 body locally to prevent heat accumulation inside the device. The temperature-controlled fan 42 serves as the second stage of heat dissipation, driving airflow through the heat dissipation duct 30 from the electrical compartment 102 to the external environment, rapidly expelling hot air from the electrical compartment 102.

[0061] This integrated heat dissipation solution, combining "equipment self-heating + active ventilation of the compartment," significantly improves the thermal management efficiency of the electrical compartment 102. On one hand, the exhaust fan 61 directly addresses the high heat flux density cooling requirements of the inverter 6, suppressing the risk of localized overheating. On the other hand, the negative pressure environment created by the temperature-controlled fan 42 accelerates the exhaust of hot air from the exhaust fan 61, while simultaneously promoting passive heat dissipation for other electrical components within the electrical compartment 102 (such as the molded case circuit breaker 96 and the high-voltage box 95). The synergistic effect of these two mechanisms ensures overall temperature uniformity within the electrical compartment 102, further guaranteeing stable operation of electrical components such as the inverter 6 within a suitable temperature range and extending equipment lifespan.

[0062] In some embodiments of this application, the energy storage cabinet 100 may further include a filter element disposed in the heat dissipation duct 30 and configured to filter the airflow flowing into the electrical compartment 102 via the heat dissipation duct 30. Specifically, when the temperature-controlled fan 42 drives external airflow through the heat dissipation duct 30 into the electrical compartment 102, the filter element can effectively intercept particulate contaminants in the airflow. For example, the filter element is made of multi-layer composite dustproof cotton, whose fiber structure can capture dust particles while maintaining airflow permeability.

[0063] See Figure 5As shown, in some embodiments of this application, the energy storage cabinet 100 may further include a spray module. The spray module includes a liquid supply pipe disposed in the cabinet 1, and the liquid inlet 71 of the liquid supply pipe is located on the outer surface of the cabinet 1. The liquid inlet 71 is used to connect to a water source. The spray module also includes at least one spray head 72, which is connected to the liquid supply pipe and is disposed in the battery compartment 101 and / or electrical compartment 102.

[0064] By pre-positioning the liquid inlet 71 on the outer surface of cabinet 1, operators can quickly access the water source without opening any cabinet doors. This design completely avoids the fatal delay of traditional fire-fighting solutions that require opening cabinet doors to locate the inlet, thus gaining crucial time for initial fire response. Furthermore, the external design of the liquid inlet 71 fundamentally eliminates the risk of oxygen influx caused by opening doors for firefighting (opening doors may exacerbate combustion), while also preventing operators from being directly exposed to high temperatures or toxic fumes. When the sprinkler head 72 is installed in battery compartment 101, it can directionally suppress flames generated by thermal runaway of battery module 5; when the sprinkler head 72 is installed in electrical compartment 102, it can effectively extinguish fires caused by short circuits in electrical components; when both compartments are covered simultaneously, a comprehensive protection network is formed, preventing the fire from spreading across compartments.

[0065] See Figures 1 to 5 As shown, in some embodiments of this application, the cabinet 1 is provided with a hoisting structure 81, which is located on the upper surface of the cabinet 1, so that operators can use hoisting tools to hoist the energy storage cabinet 100.

[0066] See Figure 1 and Figure 2 As shown, in some embodiments of this application, the cabinet 1 is provided with a forklift hole 82, which is used to cooperate with a forklift so that the operator can use a forklift to transport the energy storage cabinet 100.

[0067] See Figure 4 and Figure 5As shown, in some embodiments of this application, the energy storage cabinet 100 may further include at least one of an electricity meter 91, an air switch 92, a surge protector 93, an uninterruptible power supply 94, a high-voltage box 95, and a molded case circuit breaker 96. Among them, the electricity meter 91 is installed in the battery compartment 101 and is configured to monitor, measure and manage the flow of electrical energy in the energy storage cabinet 100; the air switch 92 is installed in the battery compartment 101 and is configured to quickly cut off the power supply when the circuit is abnormal; the surge protector 93 is installed in the battery compartment 101 and is configured to quickly conduct externally intruded overvoltages to the ground; the uninterruptible power supply 94 is installed in the electrical compartment 102 and is configured to continuously supply power when the power is abnormal; the high-voltage box 95 is installed in the electrical compartment 102 and is configured to distribute, protect and monitor high-voltage electricity; and the molded case circuit breaker 96 is installed in the electrical compartment 102 and is configured to protect the circuit from overcurrent and overload.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
