Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, and in particular to an energy storage battery pack. Background Art

[0002] When the energy storage battery is in the condition of overheating, overcharging, short circuit, collision, etc., the internal heat of the battery will accumulate and cause thermal runaway, which may cause fire or even explosion. If a single battery pack has thermal runaway and cannot be effectively controlled, it will not only spread between battery packs, but even spread to the energy storage compartments in the field, which can easily cause large-scale fires or even explosions. Therefore, the fire protection system is an important guarantee for the safe operation of the energy storage system. In the related technology, although a fire protection module is set in the energy storage battery pack, the outer shell of the energy storage battery pack is not easy to disassemble, so the fire protection module cannot be regularly replaced and maintained, resulting in a greater safety hazard of the battery.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0042] When the energy storage battery is in the condition of overheating, overcharging, short circuit, collision, etc., the internal heat of the battery will accumulate and cause thermal runaway, which may cause fire or even explosion. If a single battery pack has thermal runaway and cannot be effectively controlled, it will not only spread between battery packs, but even spread to the energy storage compartments in the field, which can easily cause large-scale fires or even explosions. Therefore, the fire protection system is an important guarantee for the safe operation of the energy storage system. In the related technology, although a fire protection module is set in the energy storage battery pack, the outer shell of the energy storage battery pack is not easy to disassemble, so the fire protection module cannot be regularly replaced and maintained, resulting in a greater safety hazard of the battery.

[0043] To solve this problem, the present application provides an energy storage battery pack 100, please refer to Figure 1-Figure 3 , Figure 1 is a schematic diagram of the structure of an energy storage battery pack provided by an embodiment of the utility model, Figure 2 is an exploded view of an energy storage battery pack provided by an embodiment of the utility model, Figure 3 yes Figure 2 The enlarged schematic diagram of the part A of the energy storage battery pack shown. The energy storage battery pack 100 includes a box body 10, a battery module (not shown in the figure) and a fire fighting module 20. The box body 10 includes a body 11 and an end cover 12. The body 11 is provided with a receiving chamber 101. The body 11 is provided with a window 102 connected to the receiving chamber 101. The end cover 12 is detachably mounted on the window 102. The battery module is arranged in the receiving chamber 101. The fire fighting module 20 is mounted on the side of the end cover 12 facing the receiving chamber 101. The fire fighting module 20 is filled with a fire extinguishing agent. Compared with the integrated closed design in the related art, when the fire fighting module 20 needs to be maintained or replaced, after the detachably connected end cover 12 is removed from the body 11, since the fire fighting module 20 is installed on the end cover 12, the fire fighting module 20 will be exposed with the removed end cover 12, which is convenient for the maintenance or replacement of the fire fighting module 20 to ensure the overall safety of the energy storage battery pack 100.

[0044] In some embodiments, the end cover 12 includes a cover plate 121 and a connecting edge 122. The cover plate 121 is convexly provided in a direction away from the accommodating chamber 101 to form a mounting groove 1211. The fire module 20 is installed in the mounting groove 1211. The connecting edge 122 is connected to the edge of the cover plate 121 and is installed on the body 11. The fire module 20 is arranged in the mounting groove 1211, which will not occupy the accommodating chamber 101, and can form a certain safety distance with the battery module and other structures in the accommodating chamber 101. Among them, the edge of the cover plate 121 can be the periphery of the cover plate 121, or it can be a partial edge of the cover plate 121, that is, the connecting edge 122 can be connected to the periphery of the cover plate 121, or it can be connected to a partial edge of the cover plate 121, such as connected to two opposite side edges of the cover plate 121. The connecting edge 122 and the cover plate 121 can be an integrally formed structure, or the connecting edge 122 can be connected to the edge of the cover plate 121 by welding or the like. Specifically, the body 11 is provided with a plurality of first mounting holes 1113, and the connecting edge 122 is correspondingly provided with a plurality of second mounting holes 1221. The energy storage battery pack 100 also includes a plurality of first fasteners 124, which may be screws, studs, bolts, etc. The first fasteners 124 are passed through the first mounting holes 1113 and the second mounting holes 1221, so that the end cover 12 can be detachably mounted on the body 11. The fastening and disassembly of the end cover 12 can be achieved by the cooperation of the first fastener 124 with the connecting edge 122 and the body 11. It is understandable that the fire protection module 20 and the end cover 12 can also be installed by plugging, snapping, etc., which is not limited in this application.

[0045] In some embodiments, the end cover 12 may also be a flat plate structure, the connecting edge 122 and the cover plate 121 are located in the same horizontal plane, the connecting edge 122 and the cover plate 121 may be an integrally formed structure, or the connecting edge 122 may be connected to the edge of the cover plate 121 by welding or the like, and the fire protection module 20 is installed on the side of the cover plate 121 facing the accommodating chamber 101.

[0046] In some embodiments, the fire module 20 is provided with a first port 22 and a second port 23, and the energy storage battery pack 100 further includes a temperature sensor, which is connected to the fire module 20 and is used to detect the temperature in the accommodating chamber 101. When the temperature in the accommodating chamber 101 exceeds the threshold temperature, the temperature sensor can activate the second port 23 to spray the fire extinguishing agent into the accommodating chamber 101. Specifically, the temperature sensor can be connected to the fire module 20 wirelessly or by wire. In some embodiments, when the temperature sensor is arranged at a position close to the fire module 20, the temperature sensor and the controller in the fire module 20 are connected by wire. In some embodiments, when the temperature sensor is arranged at a position far from the fire module 20, the temperature sensor and the controller in the fire module 20 are connected wirelessly, and wireless signal transmission is used to facilitate the layout of the temperature sensor in the accommodating chamber 101.

[0047] In some embodiments, a valve is provided at the second port 23. When the temperature in the receiving chamber 101 exceeds a threshold temperature, the temperature sensor transmits fire information to the controller, and the controller controls the valve to open, so that the fire extinguishing agent is released from the second port 23 and sprayed into the receiving chamber 101 to extinguish the fire.

[0048] In some embodiments, please refer to Figure 4-Figure 5 , Figure 4 is a top view of an energy storage battery pack provided by an embodiment of the utility model, Figure 5 yes Figure 4 The energy storage battery pack is shown in a cross-sectional view along AA. The fire module 20 is provided with a first port 22 and a second port 23. The energy storage battery pack 100 also includes a thermal rope 30. The thermal rope 30 is connected to the first port 22. The thermal rope 30 partially extends into the accommodation chamber 101. When the temperature in the accommodation chamber 101 exceeds the threshold temperature or an open flame appears, the thermal rope 30 can burn to trigger the second port 23 to release the fire extinguishing agent to extinguish the fire. Specifically, the fire module 20 includes a shell 21, a first tube body and a second tube body. The first tube body and the second tube body are connected to the shell 21 and protrude to the same side. The first tube body is provided with a first port 22, and the second tube body is provided with a second port 23. When the thermal rope is subjected to high temperature or open flame, it will start to burn. If the threshold temperature is set to 185°C, the thermal rope can sense the heat and self-ignite at the first time when it reaches 185°C, thereby activating the fire module 20 to spray and extinguish the fire. In some embodiments, the thermal rope 30 is connected to the gas production unit 20 in the fire protection module. After the thermal rope burns, it ignites the fire extinguishing agent in the gas production unit. The fire extinguishing agent undergoes an oxidation-reduction reaction to instantly produce a large amount of gas to open the diaphragm in the gas production unit. Then the gas is ejected from the second port 23 to form a pulse to reach the fire scene for fire extinguishing. The pulse spraying makes the initial kinetic energy of the fire extinguishing agent large, so that the fire extinguishing medium reaches the root of the flame directly, and the fire can be quickly controlled. In addition, the pulse spraying intensity is large, which can exceed the battery flame pressure to separate the combustible gas generated by the battery thermal runaway from the flame combustion zone to isolate the combustible material for fire extinguishing. This structure is small and simple, has high environmental adaptability and fast response speed, and can automatically detect and start automatic fire extinguishing without the need for an external power supply. The threshold temperature can also be 180°C, 181°C, 182°C, 184°C, etc. This application does not limit the specific value of the threshold temperature, and those skilled in the art can set it according to actual conditions.

[0049] In some embodiments, the fire module 20 includes a foot 24. In some embodiments, there may be four feet 24 connected to the four sides of the housing 21. The end cover 12 also includes a mounting plate 123. The mounting plate 123 is connected to the side of the cover plate 121 facing the accommodating chamber 101. The foot 24 is provided with a third mounting hole. The energy storage battery pack 100 also includes a mounting plate 123 and a plurality of second fasteners 25. The second fasteners 25 may be screws, studs, bolts, etc. The mounting plate 123 is provided with a fourth mounting hole. The second fasteners 25 are inserted through the third mounting hole and the fourth mounting hole so that the fire module 20 can be installed on the end cover 12. The fastening and disassembly of the fire module 20 can be achieved by the cooperation of the second fastener 25 with the fire module 20 and the cover plate 121. It can be understood that the fire module 20 and the end cover 12 can also be installed by plugging, snapping, etc., which is not limited in this application.

[0050] In some embodiments, the thermal rope 30 includes a first rope body 31 and a second rope body 32. The first rope body 31 is connected to the first port 22, and the second rope body 32 is connected to the first rope body 31 and extends toward the accommodating chamber 101. The first rope body 31 and the second rope body 32 are detachably connected. When the fire module 20 is maintained, only the first rope body 31 connected to the fire module 20 needs to be replaced, and the second rope body 32 does not need to be replaced. Compared with the related art that requires the entire rope body to be replaced together, the present application provides a design in which the first rope body 31 and the second rope body 32 are detachable, which is more convenient for local maintenance.

[0051] In some embodiments, the thermal rope 30 includes a first rope body 31 and a second rope body 32, the first rope body is connected to the first port 22, the second rope body 32 is connected to the first rope body 31 and extends toward the accommodating chamber 101, and the first rope body 31 and the second rope body 32 are an integrally formed structure. The thermal rope 30 with an integrally formed structure is simple and easy to manufacture, and has a low cost. At the same time, because the thermal rope 30 is integrally formed, there is no splicing structure in the middle, and the combustion process is stable. In a scenario where it is inconvenient to replace in sections, the user can replace the first rope body 31 and the second rope body 32 of the thermal rope 30 as a whole.

[0052] In some embodiments, the body 11 includes a top wall 111 and a side wall 112, the side wall 112 is arranged around the top wall 111, the side wall 112 is provided with a window 102, the end cover 12 is mounted on the side wall 112, the first rope body 31 is mounted on the end cover 12, and the second rope body 32 is mounted on the top wall 111. Specifically, the body 11 includes a top wall 111 and a side wall 112, the side wall 112 is arranged around the top wall 111, the end cover 12 is mounted on the side wall 112, and the side wall 112 is provided with a window 102. The side wall 112 includes two opposite side faces and two opposite end faces, the length of the side face is greater than the length of the end face, when multiple energy storage battery packs 100 are stacked, it is inconvenient to open the accommodating chamber 101 from one side of the top wall 111, and the end cover 12 is arranged on the side wall 112, so that the end cover 12 can be easily removed from the outside to replace the thermal rope 30, and the end cover 12 can be installed on the end face and is located on the other side of the switch, interface and other components.

[0053] In some embodiments, the top wall 111 includes a first end 1111 close to the end cover 12 and a second end 1112 arranged opposite to the first end 1111, and the second rope body 32 at least partially extends from the first end 1111 to the second end 1112. Specifically, since a plurality of components are arranged in the accommodating chamber 101, the second rope body 32 is arranged on the top wall 111 to better avoid the components, and the second rope body 32 includes a first part and a second part, the first part extends from the first end 1111 to the second end 1112, and the second part extends from the second end 1112 to the first end 1111. When the temperature at the second end 1112 rises or a fire occurs, the thermal rope 30 can sense the temperature or fire in time so that the fire fighting module 20 can take fire extinguishing measures.

[0054] In some embodiments, the second rope body 32 is wound around the periphery of the top wall 111 to increase the detection area. Specifically, in the prior art, the thermistor rope is relatively short and is only arranged in a relatively small area in the accommodating chamber 101, resulting in a too small temperature detection range. The top wall 111 of the present application includes two long sides connected to the side and two short sides connected to the end face. The second rope body 32 extends longitudinally along one long side toward the second end 1112, and then extends transversely along a short side away from the end cover 12, and then wraps back from the other long side. The second rope body 32 is wound around the top wall 111 as a whole, which can increase the detection area and improve the safety warning effect. In some embodiments, after the second rope body 32 is wound around the periphery of the top wall 111, it can also be wound multiple times in the direction away from the top wall 111.

In some embodiments, multiple second fixing members 50 are spaced apart on the top wall 111. Each second fixing member 50 can fix the second rope body 32. Those skilled in the art can set the distance between the second fixing members 50 according to actual conditions. The first fixing member 40 and the second fixing member 50 can improve the connection stability of the first rope body 31 and the second rope body 32 in the accommodating chamber 101 to prevent the rope body from shifting. It can be understood that the first fixing member 40 and the second fixing member 50 can be a buckle, a clamp or the like structure, and the present application does not limit this.
