Description

Technical Field

[0001] This application relates to the field of energy storage power station technology, and in particular to an energy storage power station device. Background Technology

[0002] Currently, energy storage power station equipment consists of separate units. The DC-side battery clusters are a separate system, while the AC-side power conversion system (PCS) and transformer integrated inverter / booster module are also separate systems. On-site assembly and commissioning of the energy storage power station equipment requires significant time. The wiring between the battery clusters and the inverter / booster module needs to be installed on-site. After assembly, on-site commissioning and grid connection are also lengthy, impacting the overall commissioning time of the energy storage power station equipment.

[0003] The existing battery clusters and inverter booster integrated compartments are assembled in the cabinet. For energy storage power station equipment with an integrated large cabinet that is more than 2.2m wide, the battery clusters need to be pulled out of the cabinet for maintenance. The length of the battery clusters plus the length of the handling device (which can be a forklift) means that at least 4m of space needs to be reserved in front of the cabinet door for maintenance, which poses a significant problem of occupying blank space. At the same time, the wires and liquid cooling pipes in the large cabinet are arranged in a crisscross pattern, which is not conducive to the later maintenance of individual battery clusters. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems and provide energy storage power station equipment, thereby realizing the integration of single battery clusters into battery cabinets, with several battery cabinets and inverter cabinets integrated and installed on a chassis frame. Wiring and liquid cooling pipelines are arranged within the chassis frame, reducing on-site assembly and commissioning time and facilitating the maintenance of individual battery cabinets. To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The energy storage power station equipment includes a battery system, an inverter system, and a liquid cooling system. The battery system, the inverter system, and the liquid cooling system are integrated on a chassis frame. The battery system includes several battery cabinets arranged adjacent to each other. Battery clusters are installed in the battery cabinets. The wires and liquid cooling pipes connected to the battery clusters extend from the bottom of the battery cabinets through the chassis frame to the inverter system and the liquid cooling system, respectively.

[0006] Specifically, several battery cabinets are arranged sequentially along a first direction, with the cabinet doors of the several battery cabinets located on the same side, and the cabinet walls of adjacent battery cabinets abutting each other.

[0007] Specifically, it also includes a fire protection system, which includes a gas fire cabinet mounted on the chassis frame. The gas fire cabinet is connected to the interior of each battery cabinet through a gas fire protection pipeline.

[0008] Specifically, the fire protection system also includes water pipes, one end of which is connected to an external water supply system, and the other end of which is connected to the interior of each of the battery cabinets.

[0009] Specifically, the battery cabinet is provided with a battery rack, and the battery rack is provided with several storage layers. The several storage layers are arranged longitudinally, and battery modules are placed in the storage layers. The interface ends of each battery module are located on the same side.

[0010] Specifically, the interface of the battery module includes a liquid cooling inlet and a liquid cooling outlet, and the liquid cooling pipeline includes a liquid cooling inlet pipe and a liquid cooling outlet pipe. The liquid cooling inlet pipe is connected to the corresponding liquid cooling inlet through an inlet branch pipe, and the liquid cooling outlet pipe is connected to the corresponding liquid cooling outlet through an outlet branch pipe.

[0011] Specifically, the liquid cooling inlet pipe and the liquid cooling outlet pipe are respectively arranged longitudinally on both sides of the battery rack, and the liquid cooling inlet pipe and the liquid cooling outlet pipe extend downward into the chassis frame.

[0012] Specifically, it also includes a gas fire suppression pipeline, which includes a main gas fire suppression pipeline located above the battery cabinet and branch gas fire suppression pipelines connected to the main gas fire suppression pipeline and extending into the battery cabinet; the branch gas fire suppression pipelines extend from the upper part to the lower part of the battery cabinet, and the gas fire suppression outlets of the branch gas fire suppression pipelines correspond to each of the storage layers.

[0013] Specifically, the chassis frame includes a frame body, within which are arranged a plurality of crossbeams in the same direction and at intervals. A cable trough and / or a liquid cooling tank are formed between any two crossbeams. The cable trough contains the electrical wires, and the liquid cooling tank contains the liquid cooling pipes.

[0014] Specifically, the top of the crossbeam is provided with several support seats, and the bottom of the battery cabinet is provided with several support members, with the support seats and support members being inserted into each other.

[0015] Compared with existing technologies, the beneficial effects of this utility model energy storage power station equipment are mainly reflected in:

[0016] The battery system, inverter system, and liquid cooling system are integrated onto the chassis frame. The battery system and inverter system can be jointly commissioned and tested during integration, which greatly reduces the on-site commissioning and assembly time of the energy storage power station equipment. The battery system adopts a layout of several adjacent battery cabinets. The split battery cabinets can be disassembled and separated from the chassis frame individually. Therefore, when maintaining the battery clusters in the battery cabinet, it is not limited to the space of the chassis frame, avoiding the need to reserve a large maintenance space in front of the battery cabinet door. At the same time, the electrical wires and liquid cooling pipes of each battery cabinet are led out from the chassis frame, avoiding the cross distribution of electrical wires and liquid cooling pipes, and improving the convenience and efficiency of maintenance of individual battery cabinets.

[0033] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0034] Example 1

[0035] This embodiment provides energy storage power station equipment, including a battery system, an inverter system, and a liquid cooling system. The battery system, inverter system, and liquid cooling system are integrated on a chassis frame 1. The battery system includes several battery cabinets 3 arranged adjacent to each other, and battery clusters are arranged in the battery cabinets 3. The wires and liquid cooling pipes 5 connected to the battery clusters extend from the bottom of the battery cabinets 3 through the chassis frame 1 to the inverter system and the liquid cooling system, respectively.

[0036] like Figures 1-3 As shown, in this embodiment, the first direction refers to the length direction of the battery system, and the second direction refers to the width direction of the battery system. The inverter system includes an inverter cabinet 6, and several battery cabinets 3 are arranged sequentially along the first direction. The cabinet doors 31 of the several battery cabinets 3 are located on the same side, and the cabinet walls 32 of adjacent battery cabinets 3 are abutted. The bottom of the battery cabinets 3 is detachably connected to the chassis frame 1. The inverter cabinets 6 are spaced apart on the side of the cabinet wall 32 of a battery cabinet 3. The inverter cabinet 6 is provided with a heat dissipation vent 61, and the cabinet walls 32 of the battery cabinets 3 effectively shield the heat dissipation vents 61, reducing the blockage of the heat dissipation vents 61 due to wind and sand. Integrating the battery system and the inverter system into the energy storage power station equipment can realize a large-scale energy storage DC inverter system of more than 5MWh.

[0037] The liquid cooling system includes a liquid cooling cabinet 7, which is mounted on the chassis frame 1. The liquid cooling cabinet 7 is located on the side of the inverter cabinet 6 and is positioned relative to the cabinet wall 32 of the battery cabinet 3. The liquid cooling pipes 5 connecting the battery clusters in each battery cabinet 3 are connected to the liquid cooling cabinet 7 along the chassis frame 1 to realize the circulation of the liquid coolant in the liquid cooling pipes 5 between the liquid cooling cabinet 7 and the battery clusters.

[0038] The energy storage power station equipment also includes a fire protection system, which includes a gas fire suppression cabinet 8. The gas fire suppression cabinet 8 is mounted on the chassis frame 1 and is located between the liquid-cooled cabinet 7 and the battery cabinet 3. The top of each battery cabinet 3 is connected to the gas fire suppression cabinet 8 through a gas fire suppression pipeline, so that the fire suppression gas in the gas fire suppression pipeline can be delivered from the gas fire suppression cabinet 8 into the battery cabinet 3 to achieve the function of gas fire suppression.

[0039] The fire protection system also includes a water pipe 91. One end of the water pipe 91 is connected to an external water supply system (not shown in the figure), and the other end of the water pipe 91 is connected to the top of each battery cabinet 3, so that the flowing water in the water pipe 91 can be sent from the water supply system into the battery cabinet 3 to achieve the function of water fire protection.

[0040] In this embodiment, the battery system, inverter system, and liquid cooling system are integrated onto the chassis frame 1. The battery system and inverter system can be integrated and tested during the integration process, which greatly reduces the on-site debugging and assembly time of the energy storage power station equipment. The battery system is arranged with several battery cabinets 3 adjacent to each other. The separate battery cabinets 3 can be disassembled individually and removed from the chassis frame 1 by a handling device, such as a crane. This allows for maintenance of the battery clusters in the battery cabinets 3 without being confined to the space of the chassis frame 1, avoiding the need to reserve a large maintenance space in front of the cabinet door 31 of the battery cabinets 3. At the same time, the wires and liquid cooling pipes 5 of each battery cabinet 3 are all led out from the chassis frame 1, avoiding the cross-distribution of wires and liquid cooling pipes 5, and improving the convenience and efficiency of maintaining individual battery cabinets 3.

[0041] Example 2

[0042] This embodiment optimizes the energy storage power station equipment based on the above embodiments, and in particular provides a specific implementation of the battery cabinet:

[0043] like Figure 4 , Figure 5 As shown, the battery cabinet 3 has a cabinet space, with cabinet walls 32 on the left and right sides, cabinet doors 31 and back panels 33 on the front and back sides, and a top panel 34 and a bottom panel 35 on the top and bottom of the cabinet space, respectively. The battery cabinet 3 can be a rectangular cabinet structure.

[0044] The battery cabinet 3 is equipped with a battery rack, and the battery rack is equipped with several storage layers 41. The storage layers 41 are arranged layer by layer along the longitudinal direction, and the battery modules 42 are placed in the storage layers 41. The battery rack includes side frames 43 arranged at relative intervals. Between two side frames 43, several horizontal frames 44 are arranged layer by layer along the longitudinal direction. The two ends of the horizontal frames 44 are extended laterally. A single storage layer 41 is formed between a horizontal frame 44 and a side frame 43.

[0045] The side frame 43 includes a number of side frame beams 45 arranged at intervals along the transverse direction, with both ends of the side frame beams 45 extending longitudinally. The side frame 43 and the cross frame 44 are assembled to form a stable structure for placing the battery module 42, which can be placed layer by layer in the storage layer 41.

[0046] The interface terminals of each battery module 42 are located on the same side of several storage layers 41, which facilitates the unified arrangement of the wires and liquid cooling pipes of each battery module 42. Specifically, the interface terminals of each battery module 42 face the cabinet door 31.

[0047] The interface of the battery module 42 includes a wire interface 46, a liquid cooling inlet 47, and a liquid cooling outlet 48. The wire interfaces 46 of each battery module 42 are connected in series by wires, which extend through the chassis frame 1.

[0048] The liquid cooling pipeline 5 includes a liquid cooling inlet pipe 51 and a liquid cooling outlet pipe 53. The liquid cooling inlet pipe 51 is located on the side closer to the battery module 42, and the liquid cooling outlet pipe 53 is located on the other side closer to the battery module 42. Specifically, the liquid cooling inlet pipe 51 and the liquid cooling outlet pipe 53 are respectively arranged longitudinally on both sides of the side frame 43. The liquid cooling inlet pipe 51 is connected to the liquid cooling inlet 47 of the corresponding battery module 42 through an inlet branch pipe 52, and the liquid cooling outlet pipe 53 is connected to the liquid cooling outlet 48 of the corresponding battery module 42 through an outlet branch pipe 54. Both the liquid cooling inlet pipe 51 and the liquid cooling outlet pipe 53 extend to the liquid cooling cabinet 7 through the chassis frame 1.

[0049] The liquid coolant is introduced into the battery module 42 through the liquid cooling inlet pipe 51 for circulation and heat absorption, and is then discharged to the liquid cooling cabinet 7 through the liquid cooling outlet pipe 53 for recycling. The liquid cooling cabinet 7 can exchange heat with the liquid coolant, allowing it to circulate back to the battery module 42 for heat absorption. The liquid cooling cabinet 7 is a conventional heat exchange device and will not be described in detail here.

[0050] The gas fire suppression pipeline includes a main gas fire suppression pipeline 81 located above the battery cabinet 3 and a branch gas fire suppression pipeline 82 connected to the main gas fire suppression pipeline 81 and extending into the battery cabinet 3. The branch gas fire suppression pipeline 82 extends from the upper part to the lower part of the battery cabinet 3 and is provided with a gas fire suppression outlet (not shown in the figure) corresponding to the storage layer 41. This allows the gas fire suppression outlet to perform gas fire suppression operations on the battery modules 42 in each storage layer 41. When a thermal runaway problem occurs in any storage layer 41, the branch gas fire suppression pipeline 82 can perform gas fire suppression in a comprehensive and rapid manner.

[0051] Several through holes are provided on the base plate 35 near the cabinet door 31. The through holes are used to avoid the wires and liquid cooling pipes 5, so that the wires and liquid cooling pipes 5 can pass through the chassis frame 1.

[0052] The bottom of the base plate 35 is provided with several support members 36. The support members 36 are connected to the chassis frame 1. The support members 36 are respectively located on both sides of the base plate 35 and below the cabinet wall 32. The support members 36 enhance the connection stability between the base plate 35 and the chassis frame 1, and provide auxiliary fixation for the assembly of the overall energy storage power station equipment.

[0053] The bottom of the base plate 35 is provided with several support plates 37. The support plates 37 are connected to the chassis frame 1. The support plates 37 are respectively located at both ends of the base plate 35 and below the back plate 33 and the cabinet door 31. The support plates 37 and the support members 36 together realize the fixed assembly of the battery cabinet 3 on the chassis frame 1, ensuring the stability of the battery cabinet 3 installation.

[0054] A dehumidifier (not shown in the figure) is installed on cabinet door 31. The dehumidifier is used to control the humidity balance of the cabinet space. A pressure relief valve 38 is also installed on cabinet door 31. The pressure relief valve 38 is used to control the pressure balance of the cabinet space. When the battery module 42 heats up or during gas fire suppression operations, the pressure relief valve 38 can adjust the pressure difference between the cabinet space and the external space in a timely manner.

[0055] An air intake fan (not shown in the figure) is installed on the back panel 33, and an air exhaust fan 39 is installed on the cabinet door 31. An airflow circulation is formed in the cabinet space, which can release the heat in the cabinet space in time and effectively dissipate heat from the battery module 42.

[0056] Example 3

[0057] This embodiment optimizes the energy storage power station equipment based on the above embodiments, and in particular provides a specific implementation of the chassis frame:

[0058] like Figure 4 , Figure 6 As shown, the chassis frame 1 includes a frame body 11, within which a first mounting area 12, a second mounting area 13, and a third mounting area 14 are provided. In this embodiment, the frame body 11 is a rectangular frame structure.

[0059] The first installation area 12 is used to install several adjacent battery cabinets 3. The first installation area 12 includes several crossbeams 21 arranged in the same direction and at intervals. A cable trough 22 and / or a liquid cooling tank 23 are formed between any two adjacent crossbeams 21. In this embodiment, there are two cable troughs 22, which are respectively close to both sides of the frame body 11. The cable troughs 22 are used to realize the routing of wires and avoid messy wires crossing and misalignment. In this embodiment, there is one liquid cooling tank 23. The liquid cooling tank 23 is used to realize the routing of liquid cooling pipes 5, so that the liquid cooling pipes 5 can be smoothly connected from the battery cabinet 3 to the liquid cooling cabinet 7.

[0060] The cable trough 22 and the liquid cooling tank 23 extend in the same direction along the first installation area 12. Several auxiliary beams 24 are provided between the cable trough 22 and the liquid cooling tank 23. The auxiliary beams 24 are located on the top of the crossbeam 21 and have a hollow structure. The auxiliary beams 24 enhance the connection stability between the cable trough 22 and the liquid cooling tank 23 and can also be used to insert wires and expand the wiring path of the cable trough 22.

[0061] Several reinforcing beams 25 are provided between any two adjacent crossbeams 21. The two ends of the reinforcing beams 25 are connected to the crossbeams 21 respectively. The reinforcing beams 25 can improve the overall support strength of the first installation area 12, and at the same time avoid the first installation area 12 being assembled by covering a large area of ​​the plate, thus achieving the effect of weight reduction.

[0062] Several support seats 26 are provided on the crossbeam 21. The arrangement of the support seats 26 is adapted to the arrangement of the support members 36. The support seats 26 and the support members 36 are inserted into each other. The support members 36 can be quickly connected through the support seats 26, which improves the installation efficiency of the battery cabinet 3 and the chassis frame 1.

[0063] Several mounting positions 27 are provided on both sides of the frame body 11. The mounting positions 27 can be located on the main body of the frame body 11 or connected to the extension structure of the frame body 11. The mounting positions 27 and the support plate 37 are detachably connected to realize the connection and fixation between the battery cabinet 3 and the chassis frame 1.

[0064] The second installation area 13 and the third installation area 14 are both located at the ends of the first installation area 12. The second installation area 13 is used to install the inverter cabinet 6, and the third installation area 14 is used to install the fire protection cabinet. Since the battery cabinet 3 is spaced apart from the chassis frame 1, it does not affect the extension of the wires through the cable tray 22 to the inverter cabinet 6.

[0065] The frame body 11 is provided with a mounting base 15 for installing the liquid cooling cabinet 7. The liquid cooling pipe 5 is avoided below the third installation area 14. The port of the liquid cooling tank 23 corresponds to the bottom of the liquid cooling cabinet 7, so that the liquid cooling pipe 5 in the liquid cooling tank 23 can be directly connected to the bottom of the liquid cooling cabinet 7 through the bottom of the third installation area 14, reducing unnecessary pipe layout and making assembly quick.

[0066] Several grounding points 16 are provided on the main frame 11 to facilitate direct grounding construction of energy storage power station equipment. The grounding points 16 on the main frame 11 are close to the battery cabinet 3, which effectively reduces the grounding resistance and improves the grounding effect.

[0067] The frame body 11 is provided with several fixed corner pieces 17 around its circumference, which facilitates the transportation of the chassis frame 1 by container vehicle.
