Description

Technical Field

[0001] This utility model relates to the field of battery management, and in particular to a stacked energy storage cabinet for centralized battery management. Background Technology

[0002] With the transformation of the global energy structure and the rapid development of renewable energy, energy storage technology has become crucial for regulating energy supply and demand and improving energy efficiency. As a core component of energy storage technology, the structure and function of the energy storage cabinet are particularly important. Structurally, it consists of battery modules and a cabinet. The cabinet adopts a common integrated cabinet structure, comprising a door, an outer frame, and internal electrical control components. The battery modules are placed inside after being connected via a control board and series / parallel wiring.

[0003] However, this type of centralized battery management using traditional electrical cabinet structures has many problems. The cabinet size is fixed, making it impossible to quickly expand or simplify the capacity, and there is often a problem of most of the cabinet space being occupied by empty cabinets.

[0004] In view of this, this technical solution proposes a stackable energy storage cabinet for centralized battery management. It adopts a stackable assembly structure, modularizes a set of cabinets, and multiple sets of cabinets can be placed in a stacked block manner. It also adopts a stepped limiting structure, which makes it stable after stacking, not easy to tip over, easy to pick up and put away, and can realize rapid addition and removal. It is easy to centralize management and reduce unnecessary space occupation. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a stacked energy storage cabinet for centralized battery management, addressing the problem of existing battery energy storage cabinets lacking modular assembly structures and resulting in significant space waste.

[0006] To achieve the above objectives, this utility model provides a stacked energy storage cabinet for centralized battery management, comprising a main body of the energy storage cabinet formed by sequentially stacking modular cabinet components between a top cover and a base.

[0007] The modular cabinet assembly includes a main housing with an insertion port on one side, and placement slots and protrusions respectively located on the top and bottom of the main housing. The placement slot is a recessed structure on the top of the main housing, forming a enclosure on both sides and at the rear, and gradually extending diagonally upwards from the bottom of the slot to be parallel to the main housing. The protrusion is an outwardly convex structure of the main housing, with its protruding contour corresponding to the protruding length of the placement slot and the enclosure. The protrusion gradually tapers diagonally upwards to one side until it connects with the main housing. Insertion seats are provided inside the placement slot and at the bottom of the protrusion.

[0008] Each of the modular cabinet components can be freely disassembled and stably stacked with end-to-end positioning through the placement slots and the bosses.

[0009] As a further embodiment of this utility model, the insertion port is provided with a sleeve, and the top and bottom of the sleeve are provided with connectors. A movable plate is provided at the front end of the sleeve, and the movable plate is a double-door structure assembled by spring bolts.

[0010] As a further embodiment of this utility model, the main housing is provided with side beams to enhance rigidity. The side beams are arranged on opposite sides along the Y-axis, and a fixing frame for enhancing the support of the internal battery pack is provided between the side beams.

[0011] As a further improvement of this utility model, a heat dissipation grid is provided on the main housing for heat dissipation of the internal battery pack.

[0012] As a further improvement of this invention, a positioning post for quick docking is provided near the plug-in socket.

[0013] As a further embodiment of this utility model, the back of the main housing is provided with fixing holes for fixed assembly.

[0014] As a further embodiment of this utility model, the top cover is provided with a control device inside and a control panel outside. The bottom of the top cover and the top of the base are the same as the stacking limiting structure of each modular cabinet component.

[0015] The beneficial effects of this utility model are as follows:

[0016] This technical solution utilizes a modular cabinet component with a top-mounted, three-sided enclosure and a forward-sloping placement slot, along with a bottom-profile-matching boss to form a stepped limiting structure. This achieves self-locking and anti-detachment during stacking, as well as lateral offset. The number of modules can be freely increased or decreased to eliminate space redundancy and improve space utilization. The insert's housing and its spring-bolt-equipped hinged door allow for rapid sealing and maintenance of the battery pack. The side beams and fixing frames located on opposite sides along the Y-axis inside the main housing significantly enhance load-bearing capacity and resistance to deformation. The unified limiting structure of the top cover and base ensures seamless engagement between the control unit and the stacked modules, ultimately forming a centralized management solution that is "expandable on demand and robust and intelligent," greatly reducing expansion costs.

[0032] as follows:

[0033] Please see the appendix Figure 1-12 ,

[0034] Each modular cabinet component (11) in this design features a placement slot (112) at the top with three-sided enclosures (113) and a front-sloping bottom. The bottom boss (117) perfectly matches the placement slot (112) through its outward convex profile and upward-sloping tapering structure. During stacking, the boss (117) is embedded in the placement slot (112) of the upper component, the enclosures (113) restrict lateral displacement, and the slope engages with the inclined surface of the boss (117) to prevent forward and backward sliding (e.g., ...). Figure 4 / Figure 6 As shown), the modules are physically and stably stacked, and are quickly electrically connected to each other via connectors (115). Users can add or remove cabinet components (11) as needed. For example, if only 3 sets of batteries are needed, 3 modules can be stacked. Subsequent expansion can be achieved by simply adding new modules (without replacing the entire cabinet), eliminating space redundancy. The structure of the placement slot (112) and the boss (117) allows for disassembly and assembly like "building blocks". That is, the modules can be separated by lifting upwards (overcoming the slope resistance), and the limit lock can be completed by pressing downwards (as shown). Figure 3 / Figure 5 As shown in the figure, it enables free disassembly and assembly in seconds.

[0035] Reference Appendix Figure 10-12 In a preferred embodiment of this utility model, the present technical solution preferably provides a sleeve (1110) for preventing the battery from entering inside the insertion port (111). The top and bottom of the sleeve (1110) are provided with connectors (1111) to achieve a stable electrical connection. A movable plate (1113) is provided at the front end of the sleeve (1110). The movable plate (1113) adopts a double-door structure assembled with spring bolts (1112), which allows the user to easily push the battery into the door panel to achieve quick opening and closing (the spring bolts (1112) provide a self-locking function), thereby improving assembly efficiency, preventing dust intrusion and reducing operational errors, and achieving safe and reliable modular maintenance.

[0036] Reference Appendix Figure 9In a preferred embodiment of this utility model, the present solution preferably involves providing side beams (1101) inside the main housing (110) to enhance rigidity. These side beams (1101) are arranged on opposite sides along the Y-axis to form a symmetrical frame. Fixing frames (1102) are added between the side beams (1101) to enhance the support of the internal battery pack. This significantly improves the overall structural rigidity, effectively distributes the weight load of the battery pack, prevents the cabinet from twisting or cracking during multi-module stacking, ensures that the battery pack is firmly fixed during transportation or use, avoids damage to internal components caused by vibration, greatly enhances the durability of the cabinet, extends its service life, and reduces safety risks.

[0037] Reference Appendix Figure 8 In a preferred embodiment of this utility model, a special heat dissipation grid (119) is provided on the main housing (110) to enhance air circulation efficiency, promote timely heat dissipation, prevent the battery pack from overheating when densely stacked or under high load, improve overall operational stability and safety, and extend battery life.

[0038] In a preferred embodiment of this utility model: preferably, a positioning post (116) is added near the plug-in base (115) so that the upper and lower modular cabinet components (11) can be precisely guided by mechanical pre-positioning during the stacking process. That is, when the boss (117) is embedded in the placement slot (112), the positioning post (116) is inserted into the corresponding card hole first (e.g., Figure 4 / Figure 6 As shown), the forced correction of the mating angle of the connector (115) enables quick insertion, shortens the assembly time, and avoids bending and damage to the pins.

[0039] Reference Appendix Figure 4 In a preferred embodiment of this utility model, a back plate (118) and fixing holes (114) for fixed assembly are provided on the back of the main housing (110), which significantly improves the structural integrity of the cabinet. The back plate (118) provides quick maintenance (batch removal of the housing (1110), battery pack and quick inspection, etc.), while the fixing holes (114) allow bolts or anchors to be directly locked to the wall or ground, so as to achieve quick and firm assembly.

[0040] Reference Appendix Figure 3-6In a preferred embodiment of this utility model: In this preferred embodiment, the top cover (10) is equipped with a control device inside and a control panel outside to achieve centralized intelligent management. At the same time, the bottom of the top cover (10) and the top of the base (12) are the same as the stacking limiting structure of each modular cabinet component (11) (i.e., they are all equipped with placement slots (112) and bosses (117)). This ensures that the entire stacking structure forms a unified stepped limiting assembly from the top cover (10) to the base (12). When the top cover (10) and the base (12) are the starting point and the ending point of the stack, their placement slots (112) or bosses (117) can be seamlessly engaged with the adjacent modular cabinet components (11), eliminating connection gaps, preventing shaking or falling off due to structural differences, greatly improving the overall stacking stability, simplifying expansion operations (such as directly stacking new modules without affecting the control unit), and achieving efficient integrated monitoring and maintenance.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the present utility model's technical concept and the contents of the present utility model's technical solution specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
