The application of this technology helps to improve energy utilization efficiency, reduce operating costs, and to a certain extent, reduce the impact on the environment.

[0003] Currently, most industrial and commercial energy storage systems on the market adopt a high cabinet integrated design, which usually has a large energy storage capacity. In actual applications, the height of the energy storage cabinet generally reaches 2.4 meters, greatly limiting its flexibility during transportation and installation, especially when facing low spaces such as basements where transportation and installation are impossible. Secondly, the high cabinet integrated energy storage system has a small floor area but can weigh up to 3 tons, and the highly concentrated weight poses potential structural risks to the infrastructure.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by this application.

[0029] The present utility model discloses a structure of an industrial and commercial energy storage system, which is used to solve the transportation and installation space limitations of traditional high cabinet integrated energy storage systems, and will be described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figures 1 to 3 , an embodiment of the industrial and commercial energy storage system structure provided by this application includes:

[0031] The first battery compartment cabinet 1, the second battery compartment cabinet 2, the electrical integration compartment cabinet 3, and the I-beam base 4;

[0032] The first battery compartment cabinet 1, the second battery compartment cabinet 2, and the electrical integration compartment cabinet 3 are integrally arranged side by side on the I-beam base 4, and the height from the bottom of the I-beam base 4 to the first battery compartment cabinet 1, the second battery compartment cabinet 2, or the electrical integration compartment cabinet 3 is less than a preset height.

[0033] In this embodiment, the structure of the traditional high cabinet integrated energy storage system is changed from one-compartment integration to three-compartment discrete integration. Among them, the first battery compartment cabinet 1 and the second battery compartment cabinet 2 are the energy storage parts of the energy storage system. The first battery compartment cabinet 1 and the second battery compartment cabinet 2 each contain a certain number of battery packs, and these battery packs are combined in series and parallel to meet the voltage and capacity required by the energy storage system. The electrical integration compartment cabinet 3 is the power control and conversion center in the energy storage system, integrating a variety of key devices and systems except the battery packs to ensure the efficient operation of the energy storage system and the intelligent management of energy.

[0034] The first battery compartment cabinet 1, the second battery compartment cabinet 2, and the electrical integration compartment cabinet 3 are integrally arranged side by side on the I-beam base 4, and the I-beam base 4 provides a stable support structure for the entire energy storage system. The I-beam base 4 is composed of two I-beam crossbeams and four I-beam longitudinal beams. The two I-beam crossbeams are respectively connected to the two ends of the four I-beam longitudinal beams. The distances between the four I-beam longitudinal beams are respectively equal to the widths of the first battery compartment cabinet 1, the second battery compartment cabinet 2, and the electrical integration compartment cabinet 3, ensuring that the weights of the first battery compartment cabinet 1, the second battery compartment cabinet 2, and the electrical integration compartment cabinet 3 can be evenly distributed on the entire I-beam base, reducing local stress concentration. The I-beam base 4 can provide high bending and torsional resistance, can withstand large loads, and makes the weight distribution of the energy storage system more uniform rather than concentrated on a single high cabinet, thereby reducing the pressure on the ground bearing and avoiding ground damage or structural risks that may be caused by weight concentration. Ensure the safety and stability of the entire energy storage system.

[0035] The overall height after the installation of the first battery compartment cabinet 1, the second battery compartment cabinet 2, the electrical integration compartment cabinet 3 and the I-beam base 4 is less than the preset height, which can be specifically controlled between 1.6 m and 2 m. This specifically solves the problem that the high-cabinet integrated industrial and commercial energy storage system cannot enter the underground parking lot through transportation, meets the market demand, and expands the potential application scope of the energy storage system.

[0036] In this embodiment, by dividing the industrial and commercial energy storage system structure into three independent compartment cabinets: the first battery compartment cabinet 1, the second battery compartment cabinet 2 and the electrical integration compartment cabinet 3, modular design is realized, allowing each compartment cabinet to be independently transported, installed, maintained and upgraded, improving the flexibility and scalability of the system. Since the overall height of the first battery compartment cabinet 1, the second battery compartment cabinet 2, the electrical integration compartment cabinet 3 and the I-beam base 4 is less than the preset height, the space limitation during transportation and installation is reduced, especially suitable for basements, underground parking lots or other low and narrow spaces with height limitations. And the I-beam base 4 can not only provide strong support, but also help to disperse the weight of the compartment cabinet, reduce the pressure on the ground, and improve the stability and safety of the overall structure.

[0037] In some alternative embodiments, the first battery compartment cabinet 1 is arranged on one side of the I-beam base 4, the electrical integration compartment cabinet 3 is arranged on the other side of the I-beam base 4, and the second battery compartment cabinet 2 is arranged between the first battery compartment cabinet 1 and the electrical integration compartment cabinet 3.

[0038] In this embodiment, through the layout design of the first battery compartment cabinet 1 - the second battery compartment cabinet 2 - the electrical integration compartment cabinet 3, the cables from the first battery compartment cabinet 1 and the second battery compartment cabinet 2 can be sequentially connected to the electrical integration compartment cabinet 3, reducing the bending and turning of the cables, simplifying the wiring path, and improving the wiring neatness. At the same time, such a layout can reduce the crossing between cables, improve the maintenance efficiency and improve the stability and reliability of the overall energy storage system.

[0039] In some alternative embodiments, several groups of L-shaped support plates are arranged on the inner walls of the first battery compartment cabinet 1 and the second battery compartment cabinet 2, and battery pack modules 5 are detachably installed on the several groups of L-shaped support plates.

[0040] In this embodiment, several groups of L-shaped support plates are provided on the inner walls of the first battery compartment cabinet 1 and the second battery compartment cabinet 2. The L-shaped support plates provide the structural stability required for the battery pack module 5. The battery pack module 5 is fixed on the L-shaped support plates and can resist gravity and vibrations that may occur during transportation. The battery pack module 5 is specifically installed on the L-shaped support plates in a detachable manner, facilitating maintenance, replacement, or upgrade. It should be noted that the size of the L-shaped support plates can be customized according to the size and shape of the battery pack module 5 to provide the required support and fixing method to adapt to different models of the battery pack module 5.

[0041] In some alternative embodiments, a liquid cooling unit 31 is provided inside the electrical integration compartment cabinet 3;

[0042] Liquid cooling plates are provided on the several groups of L-shaped support plates. The battery pack module 5 is detachably installed on the liquid cooling plates, and the liquid cooling plates are connected to the liquid cooling unit 31.

[0043] In this embodiment, overheating is one of the potential safety risks of the energy storage system. By providing a liquid cooling unit 31 inside the electrical integration compartment cabinet 3, the risk caused by overheating of the energy storage system can be reduced, and the safety of the entire energy storage system can be improved. Specifically, the liquid cooling unit 31 is connected to several groups of liquid cooling plates in the first battery compartment cabinet 1 and the second battery compartment cabinet 2. The liquid cooling plates are fixed on the L-shaped support plates on the inner walls of the first battery compartment cabinet 1 and the second battery compartment cabinet 2, and the battery pack module 5 is installed on the liquid cooling plates in a detachable manner. The liquid cooling plates are in direct contact with the battery pack module 5 to achieve efficient heat exchange. This direct contact can quickly transfer the heat generated by the battery to the liquid cooling plates, and then the liquid cooling unit 31 drives the liquid flow inside the liquid cooling plates to take away the heat. Through the liquid cooling unit 31, the heat generated by the battery pack module 5 during charge and discharge can be more precisely managed and dispersed, avoiding local overheating.

[0044] In some alternative embodiments, a power conversion module 32, a DC power distribution module 33, and an AC power distribution module 34 are provided inside the electrical integration compartment cabinet 3;

[0045] The power conversion module 32 is provided at the top of the electrical integration compartment cabinet 3, the DC power distribution module 33 is provided below the power conversion module 32, the AC power distribution module 34 is provided below the DC power distribution module 33, the battery pack module 5 is connected to the power conversion module 32, and the power conversion module 32 is connected to the DC power distribution module 33 and the AC power distribution module 34.

[0046] Among them, the power conversion module 32 (Power Conditioning System, PCS) is connected to the battery pack module 5 and is responsible for converting the direct current (DC) stored in the battery pack module 5 into alternating current (AC), or converting the alternating current back into direct current. This conversion process enables the energy storage system to be compatible with the existing AC power grid system and allows electrical energy to flow between the power grid and the energy storage system. The DC distribution module 33 is responsible for the distribution and management of electrical energy on the DC side of the energy storage system to achieve DC power supply. The AC distribution module 34 is responsible for the distribution and management of electrical energy on the AC side of the energy storage system, controls the alternating current output by the power conversion module 32, and distributes the electrical energy to different loads or other parts of the energy storage system according to the grid demand or user demand.

[0047] In this embodiment, the power conversion module 32 is arranged on the top of the electrical integration cabinet 3. The power conversion module 32 usually generates a large amount of heat. Arranging the power conversion module 32 on the top of the electrical integration cabinet 3 is conducive to the rise and discharge of heat, avoiding the influence of excessive heat on the modules below. By arranging the power conversion module 32, the DC distribution module 33, and the AC distribution module 34 in layers in the electrical integration cabinet 3, the vertical space of the electrical integration cabinet 3 is reasonably utilized, making the installation of each module inside the electrical integration cabinet 3 more compact and improving the space utilization rate.

[0048] In some alternative embodiments, a fire extinguishing device 6 is provided at the bottom of the second battery cabinet 2, and fire extinguishing pipes are respectively arranged inside the first battery cabinet 1, the second battery cabinet 2, and the electrical integration cabinet 3. The fire extinguishing pipes are connected to the fire extinguishing device 6.

[0049] In this embodiment, the fire extinguishing pipes are arranged inside all the cabinets. The fire extinguishing pipes are connected to the fire extinguishing device 6 to form a unified fire extinguishing system. The fire extinguishing device 6 is specifically located at the bottom of the second battery cabinet 2, that is, at the bottom of the middle cabinet, which can reduce the total length of the fire extinguishing pipes and facilitate a quick response to fire signals from any position in the system. The fire extinguishing device 6 stores fire extinguishing agents. Combined with the sensors and control systems in the energy storage system, it can automatically spray fire extinguishing agents into the designated cabinets through the fire extinguishing pipes when a fire is detected, ensuring the effective protection of personnel and equipment safety in case of a fire.

[0050] In some alternative embodiments, a heat dissipation window is provided on the cabinet door of the electrical integration cabinet 3.

[0051] In this embodiment, a large number of electrical devices inside the electrical integration cabinet 3 generate heat during operation. By providing a heat dissipation window on the cabinet door of the electrical integration cabinet 3, the air circulation of the electrical integration cabinet 3 can be increased, helping to dissipate the internal heat, preventing the equipment from overheating, and ensuring the stable operation of the energy storage system.

[0052] In some alternative embodiments, an operation panel is provided on the cabinet door of the electrical integration cabinet 3.

[0053] In this embodiment, the operation panel is located on the cabinet door of the electrical integration cabinet 3. The operation panel includes a display screen and control buttons, allowing users to monitor the status of the energy storage system in real time, such as key parameters like voltage, current, temperature, etc.
