Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, specifically a containerized energy storage compartment. Background Technology

[0002] Currently, containerized energy storage modules primarily use lithium iron phosphate batteries, with some modules also containing lead-acid batteries. The modules are enclosed by customized shipping containers, with fixed internal voltage and capacity. Examples include standard 215kWh lithium battery modules.

[0003] Current energy storage solutions are designed based on fixed voltage levels, and different structural solutions are adopted for different needs, resulting in low adaptability between high and low voltage. Utility Model Content

[0004] The purpose of this invention is to provide a containerized energy storage compartment to solve the problem mentioned in the background art that different structural solutions are required for different needs, resulting in low adaptability between high and low pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A containerized energy storage compartment includes a compartment body, the interior of which is provided with uniformly distributed battery racks, on which battery packs are installed. There are 10 battery racks, and the number of battery packs inside one compartment is 200. By connecting 50 battery packs in series to form a battery cluster and installing it on the battery rack, two battery clusters connected in series can form a new battery cluster containing 100 battery packs.

[0007] As a further improvement of this utility model, each of the battery racks is fixedly equipped with multiple mounting plates for mounting battery packs, and two adjacent battery racks form a battery mounting frame. By attaching the battery pack to the mounting frame, the battery pack is installed and fixed.

[0008] As a further embodiment of this utility model: a composite frame is provided on each adjacent surface of the battery mounting bracket, the composite frame is formed by combining two battery brackets, and a cavity is provided in the middle of the composite frame.

[0009] As a further improvement of this utility model, the interior of the cabin is also equipped with a duct air conditioner, and the cooling system of the duct air conditioner can form air ducts at the bottom of the battery rack and in the cavity of the composite rack.

[0010] As a further embodiment of this utility model: a bottom plate is fixedly installed at the bottom of the cabin, the bottom plate divides the bottom of the cabin into two layers, and the bottom of the bottom plate is symmetrically provided with mounting grooves along the direction of the mounting frame distribution. A cover plate is engaged inside the mounting groove, and the cover plate has mounting holes with a number and position corresponding to the mounting frame.

[0011] As a further embodiment of this utility model: the mounting bracket is provided with a positioning mechanism on its side, the positioning mechanism includes interlocking locking parts, and a bolt hole for the positioning bolt to pass through is provided at the movable opening of the locking parts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When low-voltage access is required, the 200 battery packs inside the container are divided into four battery clusters, which are connected in parallel, with a total voltage of 600V. When high-voltage access is required, two battery clusters of 50 battery packs are connected in series to form a new battery cluster of 100 battery packs. Two new battery clusters of 100 battery packs can also be formed inside the container. These two new battery clusters are then connected in parallel, thus achieving different voltage outputs under the same standard container design and the same materials through different connection methods.

[0014] Furthermore, by routing the cables inside the mounting slots—essentially installing them within the first layer of the compartment—and covering them with a cover plate, the cables are sequentially passed through different mounting holes and connected to the battery packs on the mounting rack. This achieves the goal of orderly cable routing even when dealing with numerous battery packs, providing a foundation for the series connection between the aforementioned battery clusters.

[0022] Please see Figure 1 This is a schematic diagram of the overall structure of a containerized energy storage module. The device includes a module 10, inside which are 10 evenly distributed battery racks 20. Battery packs (not shown in the figure) are installed on the battery racks 20, and each module 10 contains 200 battery packs. 50 battery packs are connected in series to form a battery cluster, which is then installed on the battery rack 20. Each battery cluster can be connected in series or parallel via a remote controller. In this embodiment, when low voltage is required, the 200 battery packs in module 10 are divided into 4 battery clusters, which are connected in parallel, with a total voltage of 600V. When high voltage is required, two battery clusters of 50 battery packs are connected in series to form a new battery cluster of 100 battery packs. Two new battery clusters of 100 battery packs can also be formed within module 10. These two new battery clusters are then connected in parallel, thus achieving different voltage outputs under the same standard module design and with the same materials through different connection methods.

[0023] Furthermore, such as Figure 2 As shown, each battery rack 20 is fixedly equipped with multiple mounting plates 21 for mounting battery packs. Two adjacent battery racks 20 form a battery mounting frame 22. By overlapping the battery pack onto the battery mounting frame 22, the battery pack is installed and fixed. Multiple evenly distributed support rods 23 are fixedly installed at the bottom of each battery rack 20. In this embodiment, the design of the support rods 23 allows the battery rack 20 to be moved away from the bottom of the housing 10, thus leaving a certain space between the battery rack 20 and the bottom of the housing 10 for heat dissipation.

[0024] A composite frame 30 is provided on each adjacent surface of each battery mounting bracket 22. The composite frame 30 is formed by combining two battery brackets 20, and a cavity is provided in the middle of the composite frame 30. Because battery packs are installed on both sides of the composite frame 30, a lot of heat is generated on the composite frame 30. The cavity design can better dissipate heat.

[0025] The interior of the cabin 10 is also equipped with a ducted air conditioner 40. Through the cooling system of the ducted air conditioner 40, air ducts can be formed at the bottom of the battery rack 20 and in the cavity of the composite rack 30. The air ducts can carry away the heat generated by the battery pack during operation and exhaust it through the ventilation ports (not shown in the figure) provided on the cabin 10. This achieves a highly efficient heat dissipation effect.

[0026] like Figure 3 and Figure 4 As shown, a base plate 50 is fixedly installed at the bottom of the cabin 10, dividing the bottom of the cabin 10 into two layers. The bottom of the base plate 50 has symmetrically formed mounting grooves 11 along the distribution direction of the battery racks 20. A cover plate 12 engages inside the mounting grooves 11, and the cover plate 12 has mounting holes 13 with a number and position corresponding to the battery racks 20. In this embodiment, the cables are arranged inside the mounting grooves 11, which can also be considered as being installed in the first layer of the cabin 10. With the cover plate 12 closed, the cables are sequentially passed through different mounting holes 13 and connected to the battery packs on the battery racks 20. This achieves the goal of orderly wiring even when dealing with numerous battery packs, providing a wiring basis for the series connection between the aforementioned battery clusters.

[0027] However, as Figure 5 As shown, since the battery rack 20 is vertically installed inside the cabin 10, the battery packs are also arranged vertically. To allow the cables to be distributed upwards, a positioning mechanism 60 is provided on the side of the battery rack 20. The positioning mechanism 60 includes interlocking locking members 61, and bolt holes 62 for positioning bolts to pass through are provided at the movable openings of the locking members 61. In this embodiment, when the cable is connected to the battery rack 20 through the mounting hole 13, the cable passes through the locking members 61 on the positioning mechanism 60, and is separated according to the layer arrangement of the battery packs. Each layer is connected to the corresponding layer of the battery pack. After the connection is completed, the locking members 61 are fixed by the positioning bolts passing through the bolt holes 62, thereby achieving the binding and fixing of the cable.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
