[0049] The container type battery energy storage system has good application prospect in solving the peak valley regulation of power grid and relieving the energy shortage status in the field of large-scale energy storage. Meanwhile, with the increasing demand of battery energy storage application, the construction of fast and mobile characteristics becomes the new requirement of demand side to energy storage system, and the container type lithium ion battery energy storage system emerges as the times require. Although the energy storage market develops rapidly, since the battery itself is an energy-containing material, the risk of thermal runaway cannot be ignored, especially in the energy-intensive place such as battery energy storage cabinet, once the thermal runaway occurs, the rapid spread of thermal runaway may cause great loss to life and property, so the fire protection in the cabinet is the last guarantee after the thermal runaway of the energy storage cabinet, and the fire protection performance is particularly important.

[0050] At present, due to the small volume of industrial and commercial energy storage cabinet, the scheme and structure of fire protection are greatly tested. The existing distributed fire protection occupies large space, and the wiring is complex, which affects the appearance and greatly increases the cost of product, reduces the competitiveness of product.

[0051] Therefore, in order to solve the technical problems of large space occupation and complex wiring of the existing distributed fire protection in the cabinet, with reference to Figures 1 to 5The utility model provides an energy storage cabinet 10, this energy storage cabinet 10 is provided with cabinet storehouse 11, be provided with a plurality of battery group 100, control device 200 and connecting pipeline 300 in cabinet storehouse 11.A plurality of battery group 100 is stacked along the gravity direction X (i.e. vertical direction) and is set up, and a plurality of battery group 100 is all provided with first connecting interface 110.Control device 200 is set up in the top of cabinet storehouse 11 along the gravity direction X (i.e. vertical direction), for example, control device 200 can be stacked in the uppermost of a plurality of battery group 100, or control device 200 can also be connected in the storehouse top of cabinet storehouse 11 (the connecting mode of control device 200 on the storehouse top is not limited to bolt fixed connection, clamping, magnetic attraction type connection and the like).Control device 200 is provided with second connecting interface 210.Corresponding to first connecting interface 110, connecting pipeline 300 is provided with a plurality of first connecting joint 310, and first connecting joint 310 and first connecting interface 110 are connected (for example, first connecting joint 310 and first connecting interface 110 can be screwed between, or first connecting joint 310 and first connecting interface 110 can be clamped, or first connecting joint 310 and first connecting interface 110 can be connected by magnetic attraction).Corresponding to second connecting interface 210, connecting pipeline 300 is provided with second connecting joint 320, and second connecting joint 320 and second connecting interface 210 are connected (for example, second connecting joint 320 and second connecting interface 210 can be screwed between, or second connecting joint 320 and second connecting interface 210 can be clamped, or second connecting joint 320 and second connecting interface 210 can be connected by magnetic attraction).Wherein, connecting pipeline 300 is used for transporting the flame retardant medium in control device 200 to a plurality of battery group 100.For example, the flame retardant medium can be fire water, or the flame retardant medium can also be nitrogen, carbon dioxide and other flame retardant gas.

[0052] Specifically, in the embodiment, when the battery group 100 occurs thermal runaway, the control device 200 controls the flame retardant medium to flow into the battery group 100 along the connecting pipeline 300, carries out fire-fighting treatment on the battery group 100, prevents the further spread of the battery group 100 thermal runaway, and avoids causing major losses of life and property. Since the control device 200 is arranged at the top of the cabinet storehouse 11, compared with arranging the control device 200 at the side or bottom of the cabinet storehouse 11, the connecting pipeline 300 connected with the control device 200 can be naturally connected to the plurality of battery group 100, avoiding the winding of the connecting pipeline 300 to cause the pipeline in the cabinet storehouse 11 to be messy, affecting the aesthetics in the cabinet storehouse 11, and also occupying a large space in the cabinet storehouse 11.

[0053] The energy storage cabinet 10 provided by the embodiment rationally utilizes the space in the cabinet bin 11, improves the space utilization in the cabinet bin 11 by optimizing the relative arrangement between the control device 200 and the plurality of battery groups 100, and simplifies the wiring mode of the connecting pipeline 300, thereby facilitating the reduction of the design volume of the energy storage cabinet 10 and the reduction of the design cost of the energy storage cabinet 10.

[0054] In some embodiments, the control device 200 is provided with a storage member (not shown in the figure) for storing the fire-retardant medium, and the storage member is in communication with the second connecting interface 210. For example, if the fire-retardant medium is fire-fighting water, the storage member can be a water bag. If the fire-retardant medium is inert gas, the storage member can be a gas bag. Specifically, in the embodiment, when the control device 200 detects that the battery group 100 has thermal runaway, the control device 200 controls the valve of the connecting pipeline 300 to open, so that the fire-retardant medium in the storage member first flows into the connecting pipeline 300 through the second connecting interface 210, and then the fire-retardant medium is transmitted by the connecting pipeline 300, and finally the fire-retardant medium flows into the battery group 100 through the first connecting interface 110, thereby achieving the cooling or fire-retardant treatment of the battery group 100 by the fire-retardant medium, and ensuring the use safety of the battery group 100.

[0055] In some embodiments, the control device 200 can accurately sense the battery group 100 having thermal runaway, and then control the corresponding valve to open, so that the fire-retardant medium can flow into the corresponding battery group 100 having thermal runaway along the connecting pipeline 300, thereby improving the control effect of the control device 200 on the thermal runaway of a single battery group 100.

[0056] In some embodiments, with reference to Figure 2 and Figure 3 , the control device 200 is provided with a discharge port 220 in communication with the storage member, and the discharge port 220 is used for discharging the fire-retardant medium into the cabinet bin 11. Specifically, in the embodiment, when the control device 200 detects that the battery group 100 has thermal runaway, the control device 200 controls the valve of the discharge port 220 to open, so that the fire-retardant medium in the storage member can be discharged into the cabinet bin 11 through the discharge port 220, and the cabinet bin 11 is subjected to overall cooling or fire-retardant treatment, thereby improving the cooling or fire-retardant effect of the fire-retardant medium on the energy storage cabinet 10, and ensuring the use safety of the energy storage cabinet 10.

[0057] In some embodiments, with reference to Figures 3 to 5The first connecting joint 310 is provided with a first plug pipe 311 extending outward, and the first plug pipe 311 is provided with a first plug part. The first connecting interface 110 is provided with a second plug part, and the second plug part and the first plug part are matched with each other to realize clamping between the first plug pipe 311 and the first connecting interface 110. For example, the first plug part can be a plug groove, and the second plug part can be a plug block. Alternatively, the first plug part can be a plug block, and the second plug part can be a plug groove.

[0058] Specifically, in the embodiment, by providing the first plug pipe 311 on the first connecting joint 310 and assembling the first plug pipe 311 and the first connecting interface 110, the connection difficulty between the first connecting joint 310 and the first connecting interface 110 is reduced, the first connecting joint 310 and the first connecting interface 110 can be quickly installed and disassembled, and the time for assembling the first connecting joint 310 and the first connecting interface 110 is saved. And through the first plug pipe 311, the connection stability and sealing performance between the first connecting joint 310 and the first connecting interface 110 are improved, and the leakage of the flame-retardant medium at the connection between the first connecting joint 310 and the first connecting interface 110 is prevented, and the waste of the flame-retardant medium is caused.

[0059] The clamping connection mode is adopted between the first plug pipe 311 and the first connecting interface 110, which is simple and fast to install, has high assembly precision, good sealing performance, is convenient for maintenance and assembly, and is not affected by external factors such as vibration or temperature, which is beneficial to maintain the connection stability.

[0060] Similarly, the second connecting joint 320 is provided with a second plug pipe 321 extending outward, and the second plug pipe 321 is provided with a third plug part. The second connecting interface 210 is provided with a fourth plug part, and the fourth plug part and the third plug part are matched with each other to realize clamping between the second plug pipe 321 and the second connecting interface 210. For example, the third plug part can be a plug groove, and the fourth plug part can be a plug block. Alternatively, the third plug part can be a plug block, and the fourth plug part can be a plug groove.

[0061] Specifically, in the embodiment, by arranging the second connecting joint 320 with the second plug-in pipe 321, and assembling the second connecting joint 320 and the second connecting interface 210 by using the second plug-in pipe 321 and the second connecting interface 210, the connection difficulty between the second connecting joint 320 and the second connecting interface 210 is reduced, the second connecting joint 320 and the second connecting interface 210 can be quickly installed and disassembled, and the time for assembling the second connecting joint 320 and the second connecting interface 210 is saved. Moreover, by the second plug-in pipe 321, the connection stability and the sealing performance between the second connecting joint 320 and the second connecting interface 210 are improved, and the leakage of the fire-retardant medium at the connection between the second connecting joint 320 and the second connecting interface 210 is prevented, so that the waste of the fire-retardant medium is avoided.

[0062] The second plug-in pipe 321 and the second connecting interface 210 are connected by clamping, which is simple, fast, high in assembly precision, good in sealing performance, convenient for maintenance and assembly, and not affected by external factors such as vibration or temperature, so that the connection stability is maintained.

[0063] In some embodiments, referring to Figures 3 to 5 , the first connecting joint 310 extends outwardly and is provided with the first plug-in pipe 311, the first plug-in pipe 311 is provided with a first magnetic attraction part, the first connecting interface 110 is provided with a second magnetic attraction part, the second magnetic attraction part and the first magnetic attraction part attract each other to realize the magnetic attraction type connection between the first plug-in pipe 311 and the first connecting interface 110.

[0064] Specifically, in the embodiment, the first plug-in pipe 311 and the first connecting interface 110 are connected by the magnetic attraction type, which can simplify the connection process between the first plug-in pipe 311 and the first connecting interface 110, improve the automatic connection degree between the first plug-in pipe 311 and the first connecting interface 110, and only needs to align the first plug-in pipe 311 and the first connecting interface 110 to realize the quick connection of the two; on the other hand, the physical damage of the first plug-in pipe 311 and the first connecting interface 110 during connection is reduced, and the structural stability of the first plug-in pipe 311 and the first connecting interface 110 is ensured.

[0065] Similarly, the second connecting joint 320 extends outwardly and is provided with the second plug-in pipe 321, the second plug-in pipe 321 is provided with a third magnetic attraction part, the second connecting interface 210 is provided with a fourth magnetic attraction part, the fourth magnetic attraction part and the third magnetic attraction part attract each other to realize the magnetic attraction type connection between the second plug-in pipe 321 and the second connecting interface 210.

[0066] Specifically, in the embodiment, the magnetic attraction type connection is adopted between the second plug-in pipe 321 and the second connection interface 210. On the one hand, the connection process between the second plug-in pipe 321 and the second connection interface 210 can be simplified, and the degree of automatic connection between the second plug-in pipe 321 and the second connection interface 210 can be improved. The second plug-in pipe 321 and the second connection interface 210 only need to be aligned to realize the quick connection of the two. On the other hand, the physical damage of the second plug-in pipe 321 and the second connection interface 210 during connection can be reduced, and the structural stability of the second plug-in pipe 321 and the second connection interface 210 can be ensured.

[0067] In some embodiments, with reference to Figure 1 The energy storage cabinet 10 is provided with an air exchange device 400 (for example, the air exchange device 400 can be an exhaust fan), the air exchange device 400 is communicated with the cabinet compartment 11 (specifically, the cabinet compartment 11 and the outside can be communicated through the air exchange device 400), and is used for realizing the air exchange in the cabinet compartment 11. The air exchange device 400 and the control device 200 are electrically connected, so that the control device 200 controls the opening and closing of the air exchange device 400. Specifically, in the embodiment, when the control device 200 detects that the battery pack 100 in the cabinet compartment 11 occurs thermal runaway, the control device 200 controls the air exchange device 400 to open, and accelerates the air flow between the cabinet compartment 11 and the outside, so as to effectively realize the air exchange and heat dissipation in the cabinet compartment 11, reduce the accumulation of temperature or harmful gas in the cabinet compartment 11, and slow down the further spread of battery thermal runaway, and improve the safety performance of the energy storage cabinet 10.

[0068] In some embodiments, the plurality of battery packs 100 are electrically connected with the control device 200, so that the control device 200 controls the opening and closing of the plurality of battery packs 100. Specifically, in the embodiment, when the control device 200 detects that the battery pack 100 in the cabinet compartment 11 occurs thermal runaway, the control device 200 controls the battery pack 100 to cut off the power supply (preferably, the control device 200 controls all the battery packs 100 to cut off the power supply), so that the battery pack 100 stops working, avoids the battery pack 100 to continue to dissipate heat and causes the heat accumulation in the cabinet compartment 11, thereby slowing down the further spread of the battery pack 100 thermal runaway, and avoiding the risk of explosion of the energy storage cabinet 10 due to thermal runaway.

[0069] In some embodiments, with reference to Figure 2 and Figure 3, the control device 200 is provided with a sensor 230 for sensing the temperature in the cabinet 11 or the gas concentration in the cabinet 11. Specifically, in the present embodiment, the sensor 230 can be a composite sensor 230, i.e. the sensor 230 has multiple detection functions such as detecting temperature and detecting gas concentration. Through the sensor 230, it can be detected whether multiple parameters in the cabinet 11 deviate from the preset parameter threshold. If one of the parameters in the cabinet 11 deviates from the preset parameter threshold (for example, temperature or gas concentration), the control device 200 will control the energy storage cabinet 10 to perform corresponding actions. For example, the control device 200 can control the transportation of fire-retardant medium into the battery pack 100, or the control device 200 can control the start of the air exchange device 400, or the control device 200 can control the battery pack 100 to cut off power, etc.

[0070] Further, the sensor 230 can be directly exposed in the cabinet 11 to improve the detection sensitivity of the sensor 230 and ensure that the control device 200 can make a timely response at the first time when the energy storage cabinet 10 is abnormal.

[0071] In some embodiments, referring to Figure 2 and Figure 3 , the control device 200 is provided with a mounting handrail 240. For example, the mounting handrail 240 can be an integral molding structure with the control device 200, or the mounting handrail 240 can be welded to the control device 200, or the mounting handrail 240 can be bolted to the control device 200. The mounting handrail 240 can provide force support for the control device 200, and by holding the mounting handrail 240, it is convenient to move, install or disassemble the control device 200.

[0072] In some embodiments, the control device 200 is provided with at least a first response and a second response according to different stages of thermal runaway development of the battery pack 100. Specifically, when the temperature in the cabinet 11 is in a first temperature stage, or the concentration of harmful gas in the cabinet 11 is in a first concentration stage (i.e. when the battery pack 100 is in an early stage of thermal runaway), the control device 200 starts the first response. The first response is that the control device 200 controls the transportation of the fire-retardant medium into the battery pack 100, or the control device 200 controls the start of the ventilation device 400, or the control device 200 controls the power cut-off of the battery pack 100 (i.e. the control device 200 only controls one measure to respond to thermal runaway). When the temperature in the cabinet 11 is in a second temperature stage, or the concentration of harmful gas in the cabinet 11 is in a second concentration stage (i.e. when the battery pack 100 is in a middle-late stage of thermal runaway), the control device 200 starts the second response. The second response is that the control device 200 controls at least two measures among the transportation of the fire-retardant medium into the battery pack 100, the start of the ventilation device 400, and the power cut-off of the battery pack 100 (i.e. the control device 200 controls at least two measures to respond to thermal runaway) to quickly achieve heat exchange and dissipation in the cabinet 11.

[0073] Correspondingly, the utility model also provides a kind of energy storage system, and the energy storage system includes the energy storage cabinet 10 of any one embodiment described above.

[0074] Specifically, in the embodiment, the energy storage system using the energy storage cabinet 10 described above can simplify the wiring mode of connecting pipeline 300, improve the space utilization rate in cabinet 11 and reduce the overall volume of the energy storage system while ensuring a good and sensitive fire extinguishing system.

[0075] Thanks to the improvements of the energy storage cabinet 10 described above, the energy storage system of the embodiment has the same technical effects as the energy storage cabinet 10 described above, which will not be repeated here.

[0076] It should be noted that other contents of the energy storage cabinet 10 and the energy storage system disclosed in the utility model can be referred to the prior art, which will not be repeated here.
