Description

Technical Field

[0001] This utility model belongs to the technical field of energy storage equipment, and specifically relates to an energy storage chassis structure. Background Technology

[0002] Energy storage enclosures are the core component of residential energy storage systems. They are mainly used to store electrical energy and release it when needed to meet the power requirements of small buildings or sites. Energy storage enclosures generally include enclosures, battery packs, controllers, cooling systems, and communication interfaces.

[0003] Existing energy storage enclosures contain multiple batteries, which generate a lot of heat during operation. If the heat cannot be dissipated in time, the inside of the energy storage enclosure will overheat.

[0004] In the process of realizing this utility model, the inventors discovered that the prior art has at least the following problems:

[0005] The existing energy storage box has a small gap between the inner wall and the battery, which affects the heat dissipation of the batteries located at the edge of the energy storage box, thus affecting the battery's lifespan. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an energy storage enclosure structure. By optimizing the energy storage enclosure structure, the problem of insufficient gap between the inner wall of the energy storage enclosure and the battery affecting battery heat dissipation can be solved, thereby helping to improve the battery's lifespan.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An energy storage chassis structure includes an outer shell for housing multiple battery packs; an insulating bracket disposed on top of the battery packs; and a fixing plate disposed at the bottom of the battery packs. The insulating bracket has multiple welding areas on both sides of its width direction, with connecting pieces corresponding to the welding areas. A cable tray is provided between adjacent welding areas. The edge of the insulating bracket extends towards the fixing plate along its height direction to form a first outer edge, with multiple first positioning protrusions spaced apart along the first outer edge. The surface of the fixing plate has multiple grooves that mate with the battery packs. The edge of the fixing plate extends towards the insulating bracket along its height direction to form a second outer edge, with multiple second positioning protrusions spaced apart along the second outer edge.

[0009] In some possible implementations, a plurality of the first positioning protrusions are spaced apart along the length direction, and a plurality of the second positioning protrusions are spaced apart around the second outer edge.

[0010] In some possible implementations, the plurality of said cable slots are arranged in a sequence that intersects along the length and width directions.

[0011] In some possible implementations, the insulating bracket is provided with terminal holes and explosion-proof valve holes corresponding to the positions of the battery pack.

[0012] In some possible implementations, the sidewall of the groove is provided with an abutment portion, and the bottom of the groove is provided with heat dissipation holes and explosion-proof valve holes.

[0013] In some possible implementations, the connecting pieces are spaced apart along the length or width of the insulating support.

[0014] In some possible implementations, a motherboard and a communication board are disposed within the housing, the motherboard being electrically connected to the battery pack and the communication board being electrically connected.

[0015] In some possible implementations, the side of the housing is provided with a cooling fan, a display screen, a power port, and a network cable port, all of which are electrically connected to the motherboard.

[0016] In some possible implementations, the housing has a cavity for accommodating the battery pack, and the motherboard is disposed on one side of the cavity.

[0017] In some possible implementations, at least a portion of the first positioning protrusion and the second positioning protrusion overlap in the height direction.

[0018] One of the above technical solutions has the following beneficial effects:

[0019] This utility model optimizes the energy storage box structure by designing a first positioning protrusion on the first outer edge of the insulating bracket and a second positioning protrusion on the second outer edge of the fixing plate. This increases the gap between the inner wall of the energy storage box and the battery, forming a heat dissipation channel between the inner wall of the energy storage box and the battery. This helps improve the uniformity of heat dissipation inside the energy storage box and avoids overheating inside the energy storage box, which could affect the battery's lifespan. The edge of the insulating bracket extends along the height direction towards the fixing plate to form a first outer edge, and the edge of the fixing plate extends along the height direction towards the insulating bracket to form a second outer edge, which serves to fix the position of the battery pack and prevent the battery pack from shifting or shaking.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.

[0039] Example 1

[0040] Because the gap between the inner wall of the existing energy storage box and the battery is small, it affects the heat dissipation of the batteries located at the edge of the energy storage box, which will affect the battery's lifespan.

[0041] like Figure 1 As shown, the energy storage chassis structure of this utility model includes an outer shell 1 for housing multiple battery packs 2; an insulating support 3 disposed on the top of the battery packs 2; and a fixing plate 4 disposed on the bottom of the battery packs 2. The insulating support 3 has multiple welding areas on both sides of its width direction Y, and connecting pieces 5 are installed on the welding areas accordingly. A cable tray 6 is provided between two adjacent welding areas. The edge of the insulating support 3 extends towards the fixing plate 4 along the height direction Z to form a first outer edge 31. Multiple first positioning protrusions 32 are provided at intervals on the first outer edge 31. The surface of the fixing plate 4 is provided with multiple grooves 40 that cooperate with the battery packs 2. The edge of the fixing plate 4 extends towards the insulating support 3 along the height direction Z to form a second outer edge 41. Multiple second positioning protrusions 42 are provided at intervals on the second outer edge 41. This utility model optimizes the energy storage box structure by designing a first positioning protrusion 32 on the first outer edge 31 of the insulating bracket 3 and a second positioning protrusion 42 on the second outer edge 41 of the fixing plate 4. This increases the gap between the inner wall of the energy storage box and the battery, forming a heat dissipation channel between the inner wall of the energy storage box and the battery. This helps improve the uniformity of heat dissipation inside the energy storage box and avoids overheating inside the energy storage box, which could affect the battery's lifespan. The edge of the insulating bracket 3 extends along the height direction Z towards the fixing plate 4 to form the first outer edge 31, and the edge of the fixing plate 4 extends along the height direction Z towards the insulating bracket 3 to form the second outer edge 41, which serves to fix the position of the battery pack and prevent the battery pack from shifting or shaking.

[0042] It should be noted that the battery pack 2 includes multiple batteries. In this embodiment, the battery pack 2 includes 16 batteries, with 8 batteries arranged in a row, forming a total of two rows and eight columns of batteries. The two columns of batteries are connected by a connecting piece 5. Between adjacent rows and at the edges of the battery pack 2, the batteries are also connected by a connecting piece 5. The welding area can be understood as the area covered by the connecting piece 5. One end of the connecting piece 5 is electrically connected to the pole of one battery, and the other end of the connecting piece 5 is electrically connected to the pole of another battery, realizing the series or parallel connection of two batteries.

[0043] In the energy storage chassis structure according to the present invention, multiple first positioning protrusions 32 are arranged at intervals along the length direction X, and multiple second positioning protrusions 42 are arranged at intervals around the second outer edge 41.

[0044] In the energy storage chassis structure according to the present invention, multiple wire grooves 6 intersect and are arranged in sequence along the length direction X and the width direction Y. In this embodiment, there can be multiple wire grooves 6. A part of the wire grooves 6 are arranged along the length direction X, and another part of the wire grooves 6 are arranged along the width direction Y, forming a structure similar to "丰" as a whole. The intersection position of the wire grooves 6 is a cross-channel structure. The wire grooves 6 can be composed of multiple snap-fit structures, which is convenient for clamping the cables in the wire grooves 6, eliminating the operation of threading the wires, and helping to improve the installation efficiency of the cables.

[0045] In the energy storage chassis structure according to the present invention, the insulating bracket 3 is provided with pole holes and explosion-proof valve holes corresponding to the position of the battery pack 2. In this embodiment, adding pole holes facilitates the pole of the battery to pass through the pole holes to connect the connecting piece 5, and the shape of the pole holes matches the shape of the pole of the battery. Adding explosion-proof valve holes ensures that the function of the explosion-proof valve can be realized, that is, when the battery internal pressure rises due to overcharging, over-discharging, over-current and internal short circuit of the battery, the explosion-proof valve can automatically and quickly relieve the pressure of the battery, avoiding safety accidents caused by battery explosion.

[0046] In the energy storage chassis structure according to the present invention, the side wall of the groove 40 is provided with a contact portion 401, and the bottom of the groove 40 is provided with heat dissipation holes and explosion-proof valve holes. In this embodiment, adding the contact portion 401 can narrow the size of the opening of the groove 40 and clamp the battery, which can be understood as clamping the battery in the card slot 40, avoiding the displacement or shaking of the battery in the groove 40, and helping to improve the overall stability of the battery pack 2. Among them, adding explosion-proof valve holes matches the battery with an explosion-proof valve at the bottom, and can also ensure that the function of the explosion-proof valve can be realized, that is, when the battery internal pressure rises due to overcharging, over-discharging, over-current and internal short circuit of the battery, the explosion-proof valve can automatically and quickly relieve the pressure of the battery, avoiding safety accidents caused by battery explosion.

[0047] In the energy storage chassis structure according to this utility model, connecting pieces 5 are spaced apart along the length direction X or the width direction Y of the insulating bracket 3. In this embodiment, the connecting pieces 5 located at the two side edges are spaced apart along the length direction X, which can be understood as the connecting pieces 5 being arranged laterally, and the connecting pieces 5 located in the middle are spaced apart along the width direction Y, which can be understood as the connecting pieces 5 being arranged longitudinally, so as to realize the series or parallel connection of the batteries of the battery pack 2.

[0048] The working principle of this utility model is as follows:

[0049] This utility model optimizes the energy storage box structure by designing a first positioning protrusion 32 on the first outer edge 31 of the insulating bracket 3 and a second positioning protrusion 42 on the second outer edge 41 of the fixing plate 4. This increases the gap between the inner wall of the energy storage box and the battery, forming a heat dissipation channel between the inner wall of the energy storage box and the battery. This helps improve the uniformity of heat dissipation inside the energy storage box and avoids overheating inside the energy storage box, which could affect the battery's lifespan. The edge of the insulating bracket 3 extends along the height direction Z towards the fixing plate 4 to form the first outer edge 31, and the edge of the fixing plate 4 extends along the height direction Z towards the insulating bracket 3 to form the second outer edge 41, which serves to fix the position of the battery pack and prevent the battery pack from shifting or shaking.

[0050] Example 2

[0051] Unlike Embodiment 1, this embodiment houses a motherboard 11 and a communication board within its casing 1. The motherboard 11 is electrically connected to the battery pack 2, and the motherboard 11 is also electrically connected to the communication board. In this embodiment, the motherboard 11 can be a commercially available PLC controller or an embedded controller. The PLC controller uses a programmable memory to store programs and execute user-oriented instructions such as logic operations, sequential control, timing, counting, and arithmetic operations. It controls various types of machinery or production processes through digital or analog input / output. The embedded controller includes microprocessor chips, timers, sequence generators, or controllers to control electronic devices or devices capable of performing various automated processing tasks such as monitoring and control. The side of the casing 1 is equipped with a cooling fan, a display screen 12, a power port 13, and a network cable port 14, all of which are electrically connected to the motherboard 11. In this embodiment, the cooling fan of the outer casing 1 is located on one side of the motherboard, which can dissipate heat from the battery. That is, the hot air in the heat dissipation channel between the inner wall of the energy storage box and the battery is dissipated by the cooling fan, which can also dissipate heat from the motherboard 11, thus helping to reduce the operating temperature of the battery and the motherboard 11. In addition, a display screen 12 is added to facilitate users to intuitively monitor the remaining power of the battery pack 2 and the working status of the motherboard 11. A power port 13 is added to facilitate charging and discharging of the battery pack 2. A network cable port 14 is added to connect to the communication board, which facilitates networking of the device and realizing remote control.

[0052] The other structures are the same as in Embodiment 1, and will not be described again here.

[0053] Example 3

[0054] Unlike Embodiment 1, this embodiment has a cavity inside the outer casing 1 to accommodate the battery pack 2. A motherboard 11 is provided on one side of the cavity to prevent the motherboard 11 and the battery pack 2 from interfering with each other. At least part of the first positioning protrusion 32 and the second positioning protrusion 42 overlap in the height direction Z, so that the first positioning protrusion 32 and the second positioning protrusion 42 are subjected to uniform force, which helps to extend the service life of the first positioning protrusion 32 and the second positioning protrusion 42.
