DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some of the embodiments of the present application, and all other embodiments obtained by those of ordinary skill in the art without creative effort based on the provided drawings also belong to the protection scope of the present application.

[0041] For those skilled in the art of the present technology, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0042] Please refer to Figure 1 and Figure 2 wherein, Figure 1 is the front view of the energy storage cabinet with an integrated electric control box provided by the embodiment of the present application, Figure 2 is the rear view of the energy storage cabinet with an integrated electric control box provided by the embodiment of the present application.

[0043] In the first specific embodiment, the energy storage cabinet with an integrated electric control box provided by the present application mainly includes a cabinet body 1 and an integrated electric control box 3.

[0044] The cabinet body 1 is used to accommodate the energy storage device 2 and the integrated electric control box 3. In addition to the energy storage device 2 and the integrated electric control box 3, the cabinet body 1 also serves to accommodate other internal components.

[0045] The integrated electric control box 3 includes a box body, a first component, and a connector. The first component is located inside the box body. The connector is provided on the box body and includes a first connection end and a second connection end electrically connected. The first connection end is arranged towards the inside of the box body and electrically connected with the first component. The second connection end is arranged towards the outside of the box body and used to realize external connection of the integrated electric control box 3.

[0046] It should be noted that the first component includes but is not limited to components, terminal blocks.

[0047] In the background art, the electrical control structure of the traditional energy storage cabinet faces challenges due to the complexity of assembly, which directly affects the rapid deployment and operation efficiency of the energy storage system. To solve this problem, the present technical solution proposes an energy storage cabinet with an integrated electric control box 3. The core of the design is integration and modularization, aiming to improve overall efficiency by simplifying the assembly process.

[0048] In this scheme, the integrated electric control box 3 concentrates most of the original bottom electrical control components inside a box body. Such integrated design reduces the wiring demand inside the cabinet body 1, thereby reducing the complexity of assembly. Since the components are centrally managed, the cabinet body 1 and the electric control box 3 can be assembled independently, which allows the assembly work to be carried out in parallel, without waiting for all components to be installed one by one, thereby saving the overall assembly time. At the same time, the connector design in the integrated electric control box 3 further simplifies the assembly process. The first connection end and the second connection end of the connector are arranged towards the inside and outside of the box body respectively, making the connection of external components with the electric control box 3 direct and simple. This design reduces the complex wiring work that needs to be done inside the cabinet body 1 in traditional design, reduces the error rate, and improves the accuracy and efficiency of assembly.

[0049] In combination with the above structure and process description, it can be seen that the energy storage cabinet with the integrated electric control box 3 has at least the following beneficial effects: the energy storage cabinet simplifies the assembly process of the energy storage cabinet, improves the assembly efficiency, and solves the problem of complex assembly of the traditional energy storage cabinet electric control structure by integrating the integrated electric control box 3 and optimizing the connector design.

[0050] In some embodiments, the integrated electric control box 3 is detachably connected to the cabinet body 1 by fasteners. This design allows the electric control box 3 to be quickly disassembled and installed when needed, facilitating maintenance and upgrading while maintaining the integrity and stability of the cabinet structure.

[0051] Specifically, the advantages of the integrated electric control box 3 are as follows.

[0052] The design of the integrated electric control box 3 allows the assembly of the cabinet body 1 and the electric control box 3 to be carried out separately, which means that it can be carried out simultaneously in different work areas or work stages, without having to wait for the cabinet body 1 to be completely assembled before starting the installation work of the electric control box 3. This parallel work method significantly reduces the overall assembly time and improves production efficiency.

[0053] The connector design of the integrated electric control box 3 simplifies the wiring work. In traditional designs, the connection between external components and components inside the cabinet body 1 requires precise wiring and wiring, which not only increases the complexity of assembly, but also increases the risk of errors. In this scheme, external components only need to be connected to the connectors of the integrated electric control box 3, greatly simplifying the wiring process, reducing the difficulty of assembly, and also reducing the risk of failure due to wiring errors.

[0054] The design of the integrated electric control box 3 improves the efficiency of equipment debugging. In traditional designs, debugging work needs to be carried out after all components and wiring are installed in place, which limits the flexibility of debugging work. This scheme allows separate debugging of components inside the integrated electric control box 3, and then overall system debugging after confirmation, which not only improves the efficiency of debugging, but also helps to quickly locate and solve problems.

[0055] The design of the integrated electric control box 3 improves the maintainability of the equipment. Since the integrated electric control box 3 can be used as a universal component in different models of cabinet body 1, when replacing or repairing components, the electric control box 3 can be quickly disassembled and replaced without having to operate the entire cabinet body 1. This modular design makes maintenance work more convenient, reduces maintenance costs, and also improves the flexibility and applicability of the energy storage cabinet.

[0056] In some embodiments, the first components include a high-voltage box, a circuit breaker, an electric energy meter, and an industrial computer, which are all built-in the integrated electric control box 3 to achieve efficient electrical control and management of the energy storage cabinet. The high-voltage box is responsible for bearing and distributing high voltage, the circuit breaker is used for overload protection of the circuit, the electric energy meter monitors energy consumption, and the industrial computer serves as the control center of the entire system. Such integrated design simplifies the internal structure of the electric control box, improves the convenience of operation and the reliability of the system.

[0057] Please refer to Figure 3 and Figure 4 wherein, Figure 3 is the plug wiring diagram of the movable connector provided in the embodiments of the present application, Figure 4 is the socket wiring diagram of the movable connector provided in the embodiments of the present application.

[0058] In some embodiments, the connector includes a movable connector, which includes a socket fixed to the box and a plug matched with the socket;

[0059] The first connection end is fixed to the side of the socket facing away from the plug, and the second connection end is fixed to the side of the plug facing away.

[0060] In this embodiment, the technical solution relates to the design of a movable connector for an integrated electric control box to achieve electrical connection between the inside and outside of the electric control box. The movable connector consists of two main parts: a socket and a plug. The socket is fixed to the box, and the plug is matched with the socket, and the two are connected to realize the transmission of electrical signals.

[0061] Specifically, the socket and the plug of the movable connector are designed with specific connection ends. The side of the socket facing away from the plug is provided with a first connection end, which is used for electrical connection with components inside the box, such as high-voltage boxes, circuit breakers, etc. Correspondingly, the side of the plug facing away is provided with a second connection end, which is used for connection outside the box, realizing electrical connection between the integrated electric control box and external equipment.

[0062] The design of this movable connector makes the electrical connection of the integrated electric control box more flexible and convenient. The use of the socket and the plug not only simplifies the wiring process and reduces the assembly difficulty, but also improves the maintainability and expandability of the system. When the integrated electric control box needs to be maintained or upgraded, the plug can be simply pulled out to quickly disconnect the internal and external connections without the need for complex operations on the entire box.

[0063] In addition, the design of the movable connector helps to improve the safety of the system. Since the connection of the plug and the socket is detachable, it can quickly cut off the power supply when needed, reducing the risk of electrical failure. At the same time, this design also makes the integrated electric control box can more easily adapt to different application scenarios and needs, enhancing its versatility and applicability.

[0064] By Figure 3 and Figure 4 The wiring layout of the plug and socket of the movable connector can be more intuitively understood, Figure 3 the wiring mode corresponding to the second connection end, Figure 4 the wiring mode corresponding to the first connection end.

[0065] In some cases, the movable connector adopts an aviation plug and an aviation socket.

[0066] Please refer to Figure 5 and Figure 6 , in which, Figure 5 the external wiring diagram of the fixed connector provided by the embodiments of the present application, Figure 6 the internal wiring diagram of the fixed connector provided by the embodiments of the present application.

[0067] In some embodiments, the connector includes a fixed connector, which includes a fixed body fixed to the box;

[0068] The first connection end and the second connection end are fixed to the inner and outer sides of the fixed body.

[0069] In this embodiment, the technical solution describes the structure and wiring mode of a fixed connector, which is used to realize the stable connection between the internal components of an integrated electric control box and external devices. The fixed connector is composed of a fixed body, which is fixed on the box as the core part of the connector.

[0070] The design feature of the fixed connector is that the first connection end and the second connection end are respectively fixed to the inner and outer sides of the fixed body. Specifically, the first connection end faces the inside of the box and is responsible for electrical connection with the internal components of the box, such as high-voltage boxes, circuit breakers, etc. This internal connection is usually to connect the electrical signals or power of these components to the outside of the box to realize the control and monitoring functions of the device. The second connection end faces the outside of the box and is used to connect with external devices or cables. Such design makes external devices can establish electrical connection with internal components of the box through this fixed terminal, so as to realize the purpose of external control or data transmission.

[0071] The design of such fixed connectors simplifies the wiring process, improves assembly efficiency, and due to its fixed nature, also enhances the stability and reliability of the connection. In addition, the design of fixed connectors helps to reduce wear and failure caused by movable parts of the connector, thereby improving the durability and maintainability of the entire system.

[0072] By Figure 5 and Figure 6 The specific layout of the external and internal wires of the fixed connector can be more intuitively understood, Figure 5 the wiring mode corresponding to the second connection end, Figure 6 the wiring mode corresponding to the first connection end.

[0073] In some cases, the fixed connector adopts phoenix terminals.

[0074] It should be noted that the design of the integrated electrical control box 3 provides high flexibility and adaptability, and is not limited to using only one of the movable connector or the fixed connector. In fact, the electrical control box 3 can simultaneously use movable connectors and fixed connectors according to actual application requirements to meet different connection requirements and environmental conditions.

[0075] Specifically, the integrated electrical control box 3 can use aviation plugs and sockets as movable connectors in some cases, which is particularly advantageous in applications that require frequent plugging and unplugging or stable connection in harsh environments. Aviation plugs and sockets are widely used due to their durability and reliable connection performance, and are particularly suitable for environments that need to withstand vibration and temperature changes.

[0076] In other cases, the integrated electrical control box 3 can also use phoenix terminals as fixed connectors, which is suitable for applications that do not require frequent plugging and unplugging but require long-term stable connection. Phoenix terminals are favored for their simple and reliable connection characteristics, especially in situations that require quick wiring and simple maintenance.

[0077] Through this flexible design, the integrated electrical control box 3 can adapt to various working environments and electrical connection requirements, whether it is movable connection that requires frequent plugging and unplugging or fixed connection that requires long-term stability. This design not only improves the adaptability and reliability of the system, but also provides users with more choices and convenience, making the integrated electrical control box 3 a versatile and efficient electrical control solution.

[0078] Please refer to Figure 7 , Figure 7 The structure diagram of the energy storage cabinet with an integrated electrical control box provided by the embodiment of the present application.

[0079] In some embodiments, the interior of the cabinet body 1 is provided with a partition structure that separates the interior of the cabinet body 1 into a dedicated space for accommodating the integrated electrical control box 3, thereby achieving spatial separation between the integrated electrical control box 3 and the energy storage device 2.

[0080] In this embodiment, the design of the cabinet body 1 takes into account the optimal utilization of internal space and functional partitioning, and achieves spatial separation between the integrated electrical control box 3 and the energy storage device 2 by setting up a partition structure. This partition structure not only improves the organization and safety of the interior of the cabinet, but also helps to improve the operating efficiency and maintenance convenience of the entire energy storage cabinet.

[0081] Specifically, the partition structure divides the internal space of the cabinet body 1 into two independent areas: one dedicated space for accommodating the integrated electrical control box 3, and the other area for installing the energy storage device 2. This design allows the electrical control box 3 and the energy storage device 2 to have independent operation and maintenance spaces, thereby reducing mutual interference and influence.

[0082] The use of the partition structure brings multiple benefits. First, it enhances safety by physically separating the electrical control part and the energy storage part, reducing the risk of electrical failure or short circuit. Second, this design helps to improve heat dissipation efficiency, as the electrical control box 3 and the energy storage device 2 can be separately designed and managed for heat dissipation, avoiding heat accumulation. In addition, the partition structure also facilitates maintenance and upgrading, as when the electrical control box 3 or the energy storage device 2 needs to be repaired or replaced, workers can easily access the respective areas without having to disassemble the entire system.

[0083] It should be noted that this embodiment does not further limit the partition structure, and the partition structure can have multiple treatment strategies according to actual conditions. For example, a partition can be used as a partition structure, or the support bracket of the energy storage device 2 can be used as a partition structure, both of which should be within the scope of this embodiment.

[0084] In some embodiments, the energy storage cabinet further comprises:

[0085] The energy storage converter 4 is externally connected to the integrated electrical control box 3 along with the energy storage device 2;

[0086] The liquid cooling unit 5 is externally connected to the integrated electrical control box 3, and the liquid cooling unit 5 and the energy storage device 2 are connected through the liquid cooling pipeline 6.

[0087] In this embodiment, the design of the energy storage cabinet further expands its functions and efficiency, by integrating the energy storage converter 4 and the liquid cooling unit 5 inside the cabinet body 1, both of which are connected to the integrated electrical control box 3, forming a high-efficiency, integrated energy storage system.

[0088] The energy storage converter 4 is one of the core components in the energy storage system, which is responsible for converting the direct current (DC) stored in the energy storage device 2 into alternating current (AC) for use in the power grid or other equipment. In this embodiment, the energy storage converter 4 is directly connected to the integrated electrical control box 3. This layout can simplify electrical connections, reduce energy loss during conversion, and improve system response speed and control accuracy.

[0089] The function of the liquid cooling unit 5 is to provide cooling for the energy storage device 2 to maintain its optimal temperature operation, improve energy storage efficiency and prolong service life. The liquid cooling unit 5 is connected to the energy storage device 2 through the liquid cooling pipeline 6, ensuring efficient circulation of the cooling liquid and removing the heat generated by the energy storage device 2. In this embodiment, the liquid cooling unit 5 is also connected to the integrated electrical control box 3. This design allows the electrical control box 3 to centrally monitor and manage the liquid cooling system, optimizing cooling effect while reducing the footprint of the cooling system.

[0090] In some embodiments, the cabinet body 1 is horizontally divided into a first area 11 and a second area 12, the first area 11 is vertically divided into a third area 111 and a fourth area 112, the third area 111 is located above the fourth area 112, the second area 12 is vertically divided into a fifth area 121 and a sixth area 122, the fifth area 121 is located above the sixth area 122.

[0091] The liquid cooling unit 5 is located in the third area 111, the energy storage converter 4 is located in the fourth area 112, the energy storage device 2 is located in the fifth area 121, and the integrated electrical control box 3 is located in the sixth area 122.

[0092] In this embodiment, the space inside the cabinet body 1 is carefully designed into multiple areas to effectively manage and optimize the layout of internal components. Specifically, the cabinet body 1 is horizontally divided into two main areas: the first area 11 and the second area 12. This horizontal division design allows different functional modules to be distinguished and operated independently, while maintaining the compactness and coordination of the overall structure.

[0093] In this layout, the liquid cooling unit 5 is placed in the third area 111, which is convenient for installation and maintenance of the liquid cooling unit. The energy storage converter 4 is located in the fourth area 112, which can be conveniently connected to the integrated electrical control box 3, and is also convenient for monitoring and maintenance. The energy storage device 2 is located in the fifth area 121, as it usually has a larger volume, placing it in the middle and upper area can balance the weight distribution of the cabinet. Finally, the integrated electrical control box 3 is located in the sixth area 122, which can conveniently control and monitor the entire energy storage system, and due to its high integration, placing it in the bottom area can reduce the space requirement.

[0094] It should be noted that the separation strategy of the first area 11 and the second area 12, the third area 111 and the fourth area 112, the fifth area 121 and the sixth area 122 can still use a partition structure; in particular, taking the partition as an example, the partition horizontally separates the first area 11 and the second area 12, and taking the support bracket of the energy storage device 2 as an example, the support bracket vertically separates the fifth area 121 and the sixth area 122.

[0095] In some embodiments, the energy storage device 2 includes a battery pack, each battery pack has a corresponding support bracket for support, and under the support of the support bracket, the battery packs are vertically distributed, and the battery packs are connected in series. The first and last battery packs are connected to the integrated electric control box 3.

[0096] In this embodiment, the design of the energy storage device 2 adopts a vertical distribution mode of battery packs. This stacking not only saves space, but also facilitates management and maintenance. The connection mode between the battery packs is series connection, that is, the positive electrode of one battery pack is connected to the negative electrode of the next battery pack. Such a connection mode can increase the total voltage of the entire battery pack while maintaining the total current unchanged.

[0097] The first and last positions in the series direction, that is, the bottommost and topmost battery packs, are respectively responsible for external connection conduction with the integrated electric control box 3. One positive electrode of the bottommost battery pack is connected to the integrated electric control box 3, and one negative electrode of the topmost battery pack is connected to the integrated electric control box 3. Such a design simplifies the electrical connection between the battery pack and the electric control box, and makes the electrical configuration of the entire energy storage device 2 more efficient and compact.

[0098] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the top of the cabinet 1 is provided with lifting rings 101 and explosion venting plates 102. The lifting rings 101 are distributed at the four corner positions of the top of the cabinet 1. This distribution mode makes the cabinet 1 can be conveniently hoisted and lifted by lifting equipment, especially when the energy storage cabinet needs to be moved or installed, the lifting ring provides a stable lifting point, ensuring the safety and convenience of operation. The explosion venting plate 102 is a safety device mainly used to quickly release pressure when the internal pressure of the cabinet abnormally rises, preventing the cabinet from exploding or being damaged due to excessive internal pressure, thereby protecting personnel safety and equipment integrity. The setting of these two components enhances the practicality and safety of the cabinet 1.

[0099] In this embodiment, the front side of the cabinet body 1 is equipped with openable cabinet doors for the convenience of operation and maintenance of the internal components. In order to monitor the opening and closing state of the cabinet door in real time, ensure safety and convenience, the front side of the cabinet body 1 is provided with a travel switch 103. This travel switch 103 can send a signal when the cabinet door is opened or closed, prompting the operator of the state of the cabinet door, and can also be used to feedback to the control system whether the cabinet door is closed correctly, thereby ensuring the safe operation of the equipment.

[0100] As shown in Figure 2 The rear side of the cabinet body 1 integrates a plurality of functional components. The working condition machine antenna 104 is used for wireless communication, the nameplate 105 identifies the information of the equipment, the dehumidifier 106 is used to adjust the humidity in the cabinet, and prevent the equipment from being damp. The guide rail terminal 107 provides a quick connection and fixing method for internal components, and the electrical control box grounding row 108 and the cabinet grounding point 109 are used to ensure the safe grounding of the equipment, prevent electrical failure and lightning damage. The arrangement of these components not only enhances the functionality of the cabinet body 1, but also improves the convenience and safety of its operation.

[0101] It should be noted that many components mentioned in this application are general standard components or components known to those skilled in the art, the structure and principle of which can be known by the technical personnel through the technical manual or through the conventional experimental method.

[0102] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from another entity, and do not necessarily require or imply that there is any such actual relationship or order between these entities.
