Technical Field

[0002] With the increasingly prominent problem of climate change, it has become an important consensus to promote the transformation of the energy consumption structure towards low-carbon and clean directions globally. In this context, the development and utilization of renewable energy have become the key to achieving energy transformation, leading to the rapid development of electrochemical energy storage technology. As the core component of the electrochemical energy storage system, the market demand for energy storage battery packs is continuously expanding with the in-depth progress of the energy transformation process. Energy storage battery packs are mainly applied to the power generation side, grid side, and energy storage power stations of the power grid. Energy storage battery packs can absorb the volatility of new energy power generation (such as wind energy, solar energy) on the power generation side and convert it into a stable electrical energy output. Even when the wind speed or sunlight conditions change, the energy storage battery pack can ensure the continuity and stability of power supply. Energy storage battery packs can be used for peak shaving and frequency modulation on the grid side, storing electrical energy during low-demand periods and releasing electrical energy during peak-demand periods, thereby balancing the supply and demand relationship and improving the operation efficiency of the power grid. Energy storage battery packs in energy storage power stations can store electrical energy during valley periods with lower electricity prices and use the stored electrical energy during peak periods with higher electricity prices, thereby reducing the electricity consumption cost of users.

[0027] Figure 1FIG. 0 is a schematic structural diagram of an energy storage battery pack 100 in the prior art. In the prior art, a communication input interface 1, a communication output interface 2, a positive electrode interface 3, and a negative electrode interface 4 are on a first mounting panel 81 of an integrated plug-in unit. A fire fighting water injection port 7 is located on a second mounting panel 82. The positions of the communication input interface 1, the communication output interface 2, the positive electrode interface 3, the negative electrode interface 4, a refrigerant inlet 5, a refrigerant outlet 6, and the fire fighting water injection port 7 are relatively scattered. When the energy storage battery pack 100 is installed on the first mounting panel 81 and the second mounting panel 82, the assembly process is relatively complex, and the energy storage battery pack requires a large number of components. The large number of components also increases the volume and weight of the energy storage battery pack. The inventor thought of designing an integrally formed integrated plug-in unit that can solve the problems of complex assembly process and numerous components.

[0028] Based on this, referring to Figure 2 In a first aspect, the present invention provides an integrated plug-in unit 200 installed on an energy storage battery pack 100. The energy storage battery pack 100 can communicate with external devices and be electrically connected to other energy storage battery packs through the integrated plug-in unit 200. There is a refrigerant pipe (not shown) in the energy storage battery pack 100. The integrated plug-in unit 200 includes: a communication input interface 1 through which an external device inputs a communication signal to the energy storage battery pack; a communication output interface 2 through which the energy storage battery pack outputs a communication signal to the external device; a positive electrode interface 3 electrically connected to the positive electrode in the energy storage battery pack where the integrated plug-in unit is located; a negative electrode interface 4 electrically connected to the negative electrode in the energy storage battery pack where the integrated plug-in unit is located; a refrigerant inlet 5 communicating with the refrigerant pipe, and external refrigerant is transported to the refrigerant pipe through the refrigerant inlet 5; a refrigerant outlet 6 communicating with the refrigerant pipe, and the refrigerant in the refrigerant pipe is discharged through the refrigerant outlet 6; a fire fighting water injection port 7 through which fire fighting water is injected into the energy storage battery pack for fire fighting; a mounting panel 8 installed on the energy storage battery pack 100; wherein, the communication input interface 1, the communication output interface 2, the positive electrode interface 3, the negative electrode interface 4, the refrigerant inlet 5, the refrigerant outlet 6, and the fire fighting water injection port 7 are located on the mounting panel 8 and are integrally formed with the mounting panel 8.

[0029] Adopting the above technical solution can improve the assembly efficiency of the energy storage battery pack 100, reduce the number of components during the installation process, reduce costs, simplify the assembly process of the energy storage battery pack 100, improve the compactness and space utilization rate of the energy storage battery pack 100, reduce the volume and weight of the energy storage battery pack, and facilitate transportation and installation.

[0030] Specifically, the communication input interface 1, the communication output interface 2, the positive electrode interface 3, the negative electrode interface 4, the coolant inlet 5, the coolant outlet 6, and the fire injection port 7 are located on the mounting panel 8 and are integrally formed with the mounting panel 8. The integrally formed molding method can be die molding, where molten material is injected into a mold and cooled and solidified in the mold to form the integrated plug 200 with the desired shape.

[0031] Reference Figure 3 , Figure 3 is a schematic diagram of the connection structure of multiple energy storage battery packs. The first energy storage battery pack 101, the second energy storage battery pack 102, the third energy storage battery pack 103, and the fourth energy storage battery pack 104 form a battery cluster. The communication input interface 1 of the fourth energy storage battery pack 104 is connected to the signal input terminal 12. The communication output interface 2 of the fourth energy storage battery pack 104 is connected to the communication input interface 1 of the third energy storage battery pack 103. The communication output interface 2 of the third energy storage battery pack 103 is connected to the communication input interface 1 of the second energy storage battery pack 102. The communication output interface 2 of the second energy storage battery pack 102 is connected to the communication input interface 1 of the first energy storage battery pack 101. The positive electrode of the battery cluster 13 is electrically connected to the positive electrode interface 3 of the first energy storage battery pack 101. The negative electrode interface 4 of the first energy storage battery pack 101 is electrically connected to the positive electrode interface 3 of the second energy storage battery pack 102. The negative electrode interface 4 of the second energy storage battery pack 102 is electrically connected to the positive electrode interface 3 of the third energy storage battery pack 103. The negative electrode interface 4 of the third energy storage battery pack 103 is electrically connected to the positive electrode interface 3 of the fourth energy storage battery pack 104. The negative electrode interface 4 of the fourth energy storage battery pack 104 is electrically connected to the negative electrode of the battery cluster 14. The battery valve control terminal 15 controls the battery valve 11, and thus controls the opening and closing of the fire injection port 7 of the energy storage battery pack. Specifically, when it is necessary to inject fire water from the fire injection port 7, the battery valve 11 is powered on, and the induction coil inside the battery valve 11 generates magnetic force to open the valve inside the fire injection port 7, that is, to open the fire injection port. When it is necessary to close the fire injection port 7, the battery valve 11 is powered off, the induction coil inside the battery valve 11 does not generate magnetic force, and the valve of the fire injection port 7 closes the valve of the fire injection port 7 under the action of the elastic member inside the battery valve, that is, closes the fire injection port 7. The coolant inlet end 16 is respectively connected to the coolant inlets 5 and the fire injection ports 7 of the first energy storage battery pack 101, the second energy storage battery pack 102, the third energy storage battery pack 103, and the fourth energy storage battery pack 104. The coolant outlet end 17 is respectively connected to the coolant outlets 6 of the first energy storage battery pack 101, the second energy storage battery pack 102, the third energy storage battery pack 103, and the fourth energy storage battery pack 104.

[0032] In some embodiments, continue to refer to Figure 2, the arrangement of the contact terminals of the communication input interface 1 and the communication output interface 2 is different, and / or the arrangement of the contact terminals of the positive electrode interface 3 and the negative electrode interface 4 is different, and / or the shapes of the refrigerant inlet 5 and the refrigerant outlet 6 are different.

[0033] Specifically, the arrangement of the contact terminals of the communication input interface 1 and the communication output interface 2 is different to prevent the misinsertion of the communication input interface 1 and the communication output interface 2. The communication input interface 1 and the communication output interface 2 are designed with different numbers, shapes or specifications of contact terminals. For example, the communication input interface 1 has one or more terminals more or less than the communication output interface 2, so that they cannot be matched. Or, for example, terminals of different shapes (such as triangular, square, circular, etc.) are used, so that the communication line corresponding to the communication input interface 1 cannot be inserted into the communication output interface 2. Or, a key slot is provided on one side of the communication input interface 1, and a corresponding key cap is provided on the communication output interface 2 to ensure that it can only be inserted in a specific direction. Or, the arrangement of the card slots of the communication input interface 1 and the communication output interface 2 is different, and the arrangement of the card slots is different in the up-down or left-right direction. Or, for another example, the specification sizes of the communication input interface 1 and the communication output interface 2 are different.

[0034] Specifically, the arrangement of the contact terminals of the positive electrode interface 3 and the negative electrode interface 4 is different to prevent the positive electrode interface 3 and the negative electrode interface 4 from being connected reversely, resulting in circuit damage. The positive electrode interface 3 and the negative electrode interface 4 are designed with contact terminals of different shapes or specifications, or the arrangement order of the contact terminals is different.

[0035] Specifically, the shapes of the refrigerant inlet 5 and the refrigerant outlet 6 are different to prevent the refrigerant inlet 5 and the refrigerant outlet 6 from being connected reversely, resulting in the wrong flow direction of the refrigerant in the refrigerant pipe and reducing the refrigeration efficiency of the energy storage battery pack.

[0036] In some embodiments, the communication input interface 1 and / or the communication output interface 2 includes interface pins (PIN pins), and the surfaces of the interface pins are nickel-plated. By adopting the above technical solution, the stability of communication signal transmission can be improved. Because nickel has a low resistivity, the nickel-plated layer on the surface of the interface pin can reduce the contact resistance between the interface pin and the communication line. The lower contact resistance can make the communication signal lose less energy during transmission, thus maintaining the stability of the signal strength.

[0037] In some embodiments, the positive electrode interface 3 and / or the negative electrode interface 4 include interface pins, and the surfaces of the interface pins are silver-plated. By adopting the above technical solution, the conductivity of the positive electrode interface 3 and / or the negative electrode interface 4 can be improved. Since silver has a high conductivity and a small resistance, when the surface of the interface pin is silver-plated, the contact resistance can be significantly reduced, and the conductivity efficiency when the current passes through the positive electrode interface 3 and / or the negative electrode interface 4 can be improved. At the same time, due to the silver-plated layer having a low resistance, the resistance of the interface pin is smaller, and less heat is generated when the current passes through, which helps to reduce the temperature of the interface pin and the energy storage battery pack and reduce heat loss.

[0038] In some embodiments, a detachable first protective cover (not shown) is provided on the refrigerant inlet 5. The first protective cover covers the refrigerant inlet and is hermetically connected to the refrigerant inlet 5. A detachable second protective cover (not shown) is provided on the refrigerant outlet 6. The second protective cover covers the refrigerant outlet 6 and is hermetically connected to the refrigerant outlet 6. By adopting the above technical solution, the first protective cover and the second protective cover play a role in stopping the flow, preventing the refrigerant in the refrigerant pipe from flowing out from the refrigerant inlet 5 and the refrigerant outlet 6.

[0039] In some embodiments, the material of the mounting panel is copper alloy, aluminum alloy, zinc alloy or stainless steel.

[0040] Furthermore, the material of the integrated plug-in 200 is preferably brass material, that is, copper-zinc alloy material. The brass material has good corrosion resistance and can adapt to the use of the energy storage battery pack 100 in various environments, extending the service life of the integrated plug-in 200. The brass material has high mechanical strength, which can ensure that the integrated plug-in 200 is not easily deformed during the assembly and use of the energy storage battery pack 100 and maintain the stability of the connection.

[0041] Even further, the surface of the integrated plug-in 200 is nickel-plated to improve the corrosion resistance of the integrated plug-in 200. Nickel plating can effectively isolate the surface of the integrated plug-in 200 from contact with the external environment, preventing oxidation and corrosion. Especially in high-humidity or corrosive environments, nickel plating can significantly improve the durability of the integrated plug-in 200.

[0042] In some embodiments, continue to refer to Figure 2, the mounting panel 8 is rectangular, the mounting panel 8 has a transverse extension direction X and a longitudinal extension direction Y, and the communication input interface 1 and the communication output interface 2 are arranged at intervals along the transverse extension direction X. For example, the communication input interface 1 is located on the left side of the communication output interface 2. The positive electrode interface 3 and the negative electrode interface 4 are arranged at intervals along the transverse extension direction X. For example, the positive electrode interface 3 is located on the left side of the negative electrode interface 4. The coolant inlet 5 and the coolant outlet 6 are arranged at intervals along the longitudinal extension direction Y. For example, the coolant inlet 5 is located above the coolant outlet 6. The fire injection port 7 is arranged at an interval from the coolant inlet 5. For example, the fire injection port 7 is located at the lower right of the coolant inlet 5. With the above technical solutions, the integrated plug-in structure is compact, and the communication input interface 1, the communication output interface 2, the positive electrode interface 3, the negative electrode interface 4, the coolant inlet 5, the coolant outlet 6, and the fire injection port 7 are arranged in a specific order and direction, enabling the operator to intuitively identify the position of each interface, facilitating operation and maintenance, making it more convenient for overhaul and replacement of components, and reducing the operation difficulty. At the same time, considering the operation habits of the operator (for example, positive on the left and negative on the right) and the ergonomic principles, the operation is made more comfortable and convenient.

[0043] In some embodiments, there are a plurality of mounting holes 9 on the mounting panel 8, and the mounting panel 8 is fixedly connected to the energy storage battery pack 100 through the mounting holes 9. Specifically, the mounting panel 8 and the energy storage battery pack 100 are fixedly connected by bolts 10 passing through the mounting holes 9. With the above technical solutions, the design that there are a plurality of mounting holes on the mounting panel 8 and the mounting panel 8 is fixedly connected to the energy storage battery pack 100 through these mounting holes not only enhances the stability and safety of the system but also provides flexibility in installation, disassembly, adjustment, and maintenance.

[0044] In some embodiments, the energy storage battery pack 100 has a housing 110, and a spraying port (not shown) and a sensing device (not shown) are provided inside the housing 110. The spraying port is communicated with the fire injection port 7, and the spraying port is used to disperse the fire extinguishing water into water mist and then inject it into the housing 110. The sensing device is configured to detect the pressure of the fire extinguishing water in the housing 110, and when the pressure exceeds the threshold, the fire injection port 7 is closed. With the above technical solutions, the spraying port disperses the fire extinguishing water into water mist, increasing the contact area between the fire extinguishing water and the batteries inside the housing, improving the fire extinguishing and cooling rate of the fire extinguishing, quickly carrying out fire extinguishing, and improving the safety of the energy storage battery pack. When the sensing device detects the pressure of the fire extinguishing water inside the housing, it can avoid the waste of fire extinguishing water caused by too high water pressure and prevent the fire extinguishing water from overflowing the housing due to too much fire extinguishing water.

[0045] In a second aspect, the present invention also provides an energy storage battery pack, including the above integrated plug-in.

[0046] Adopting the above technical solution can improve the assembly efficiency of the energy storage battery pack, reduce the number of components during installation, lower costs, simplify the assembly process of the energy storage battery pack, improve the compactness and space utilization rate of the energy storage battery pack, reduce the volume and weight of the energy storage battery pack, and facilitate transportation and installation.

[0047] Although the present invention has been illustrated and described by referring to some preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions.
