[0075] An energy storage power station usually includes multiple energy storage units, which can be energy storage cabinets, energy storage containers, etc.

[0076] Thermal runaway is unavoidable during the use of energy storage units, generating large amounts of smoke. The smoke generated by thermal runaway is extremely hot and high-pressure, and is prone to explosion after accumulation.

[0077] Therefore, in some cases, each energy storage unit is generally equipped with a flue gas treatment device, which collects and treats the flue gas emitted by each energy storage unit to reduce the harm caused by thermal runaway of the energy storage unit. This arrangement makes the cost of energy storage power stations very high and the economic efficiency is poor.

By providing a first processing device connected to multiple energy storage units, the first processing device can receive the flue gas generated by multiple energy storage units during thermal runaway and remove combustible substances from the flue gas to produce less harmful gas. In other words, the first processing device can process the flue gas from multiple energy storage units. This arrangement can reduce the cost of the energy storage system, improve the economic efficiency of the energy storage system, and further improve the economic efficiency of the energy storage power station.

[0085] In some embodiments, the battery may be a battery module. When multiple battery cells are present, the multiple battery cells are arranged and secured to form a battery module. For example, the multiple battery cells may be secured to form a battery module using cable ties or other similar means. For example, the multiple battery cells may also be secured to form a battery module using end plates, side plates, or other similar means.

[0086] In other embodiments, the battery may be a battery pack, which may include a housing and battery cells. As an example, the battery cells may be directly housed in the housing. As an example, the battery cells may be first formed into a battery module and then housed in the housing.

These cells can be secondary batteries or primary batteries. They can be, but are not limited to, metal batteries, lithium-sulfur batteries, sodium-ion batteries, or magnesium-ion batteries. They can be cylindrical, flat, rectangular, or other shapes.

[0088] In some embodiments, please refer to Figure 1, which is an exploded view of a battery 11 provided in some embodiments of the present application. Battery 11 may include a housing 112 and a plurality of battery cells 111. Housing 112 has a structure with a receiving space 11201 therein. Receiving space 11201 of housing 112 is used to accommodate battery cells 111.

[0089] The housing 112 can have various structures. In some embodiments, the housing 112 can include a first portion 1121 and a second portion 1122, which overlap each other and together define the aforementioned storage space 11201. The first portion 1121 can be a hollow structure with an opening at one end, and the second portion 1122 can be a plate-like structure. The second portion 1122 overlaps the open side of the first portion 1121, so that the first and second portions 1122 together define the aforementioned storage space 11201. Alternatively, referring to FIG. 1 , the first and second portions 1121, 1122 can both be hollow structures with an opening at one end, with the open side of the first portion 1121 overlapping the open side of the second portion 1122, so that the first and second portions 1121, 1122 together define the aforementioned storage space 11201.

[0091] Please refer to Figure 2, in conjunction with the other accompanying drawings. Figure 2 is a schematic diagram of an energy storage system 100 provided in some embodiments of the present application. The energy storage system 100 provided in the embodiments of the present application includes a first processing device 20 and a plurality of energy storage units 10. The first processing device 20 is connected to the plurality of energy storage units 10 and is used to receive flue gas discharged from the plurality of energy storage units 10 and remove combustible components from the flue gas.

[0092] The energy storage unit 10 refers to a unit with an energy storage function, which may be, but is not limited to, an energy storage cabinet 10a, an energy storage container 10b, a battery 11, a single battery 11, and the like.

[0093] The first treatment device 20 is a device for treating the flue gas to remove the combustible components in the flue gas. After the first treatment device 20 treats the flue gas to remove the combustible components in the flue gas, low-hazard gas with poor combustibility can be obtained.

[0094] As an example, the first processing device 20 can remove combustible components such as carbon monoxide and hydrogen from the flue gas.

[0095] The first processing device 20 is connected to the plurality of energy storage units 10, so that the plurality of energy storage units 10 are in gas communication with the first processing device 20, thereby enabling the first processing device 20 to receive flue gas exhausted from the plurality of energy storage units 10. In this way, the flue gas exhausted from the plurality of energy storage units 10 can enter the first processing device 20 and be processed by the first processing device 20 to obtain low-hazard gas.

[0096] The energy storage system 100 provided in the embodiment of the present application utilizes a first processing device 20 connected to multiple energy storage units 10. This allows the first processing device 20 to receive flue gas generated by multiple energy storage units 10 during thermal runaway and remove combustible gases from the flue gas to produce less harmful gas. Specifically, the first processing device 20 can process flue gas from multiple energy storage units 10. This configuration reduces the cost of the energy storage system 100 and improves its economic efficiency.

[0097] It should be noted that in some cases, the flue gas discharged during thermal runaway of the energy storage unit 10 is only inerted to reduce the potential for explosion. However, since combustible components still exist in the flue gas, the energy storage system 100 still has a high potential for explosion. The energy storage unit 10 provided in the embodiment of the present application removes combustible components from the flue gas through the first processing device 20 to obtain a low-hazard gas with very few combustible components, thereby reducing the potential for explosion of the energy storage system 100.

[0098] In some embodiments, please continue to refer to FIG. 2 and other figures. The energy storage system 100 further includes a pipeline assembly 40 . The pipeline assembly 40 is used to achieve gas communication between the first processing device 20 and the plurality of energy storage units 10 .

[0099] Specifically, the pipeline assembly 40 may include multiple exhaust pipes 41, and each energy storage unit 10 is connected to the exhaust pipe 41. In addition, the exhaust pipe 41 on each energy storage unit 10 is connected to the first processing device 20, so that the first processing device 20 is connected to multiple energy storage units 10 through the exhaust pipe 41.

[0100] In some possible designs, the end of the exhaust branch pipe 41 away from the energy storage unit 10 can be directly connected to the first processing device 20. In this way, gas communication is achieved between the first processing device 20 and the energy storage unit 10 through the exhaust branch pipe 41, so that the flue gas exhausted by each energy storage unit 10 can be discharged to the first processing device 20 through the exhaust branch pipe 41.

[0101] Alternatively, in some other possible designs, as shown in FIG2 , the pipeline assembly 40 may further include an exhaust manifold 42, to which the exhaust branch pipes 41 on the multiple energy storage units 10 are connected, and the exhaust manifold 42 is connected to the first processing device 20, so that the exhaust branch pipes 41 on each energy storage unit 10 are indirectly connected to the first processing device 20 via the exhaust manifold 42. In this way, gas communication is achieved between the first processing device 20 and the energy storage units 10 via the exhaust branch pipes 41 and the exhaust manifold 42, so that the flue gas exhausted by the multiple energy storage units 10 can be gathered into the exhaust manifold 42 through their respective exhaust branch pipes 41, and then discharged to the first processing device 20 through the exhaust manifold 42.

[0102] The exhaust branch pipe 41 and the exhaust main pipe 42 both refer to pipes that can be used to pass the flue gas.

[0103] In some embodiments, referring to FIG. 2 and in conjunction with other drawings, the first processing equipment 20 includes at least one of a chemical reaction component 21 and a condensation device 22 .

[0104] Please refer to FIG. 2 . The chemical reaction component 21 is connected to the plurality of energy storage units 10 and is used to cause the combustible components in the flue gas to undergo a chemical reaction.

[0105] The chemical reaction component 21 is a component used to chemically react the combustible components in the flue gas. The chemical reaction component 21 causes the combustible components in the flue gas to react, causing them to be absorbed or reacted, thereby removing the combustible components from the flue gas and treating the flue gas into a less harmful gas.

[0106] For example, the chemical reaction component 21 can be used to cause carbon monoxide in the flue gas to undergo a reduction reaction so that the carbon monoxide is reacted away, thereby achieving a carbon monoxide removal effect.

[0107] For example, the chemical reaction component 21 can be used to burn flue gas so that carbon monoxide and hydrogen in the flue gas are burned and reacted, thereby achieving the removal effect of carbon monoxide, hydrogen, etc.

[0108] Among them, the chemical reaction component 21 is connected to multiple energy storage units 10, so that the multiple energy storage units 10 are respectively gas-connected to the chemical reaction component 21, so that the flue gas of the multiple energy storage units 10 can be discharged to the chemical reaction component 21, and a chemical reaction is carried out under the action of the chemical reaction component 21 to remove the combustible components in the flue gas.

[0109] Among them, the chemical reaction component 21 and the energy storage unit 10 can achieve gas communication through the pipeline component 40. As an example, the chemical reaction component 21 and the energy storage unit 10 can be connected through the exhaust branch pipe 41. Specifically, each energy storage unit 10 is connected to the exhaust branch pipe 41, and the exhaust branch pipes 41 on multiple energy storage units 10 are respectively connected to the chemical reaction component 21, so that the chemical reaction component 21 is connected to multiple energy storage units 10. As another example, please refer to Figure 2, the chemical reaction component 21 and the energy storage unit 10 can also be connected through the exhaust branch pipe 41 and the exhaust main pipe 42. Specifically, each energy storage unit 10 is connected to the exhaust branch pipe 41, the exhaust branch pipes 41 on multiple energy storage units 10 are connected to the exhaust main pipe 42, and the exhaust main pipe 42 is connected to the chemical reaction component 21, so that the chemical reaction component 21 is connected to multiple energy storage units 10.

[0110] In some possible designs, the flue gas exhausted by the energy storage unit 10 can be directly discharged to the chemical reaction assembly 21 through the pipe assembly 40. Alternatively, in other possible designs, a condensing device 22, a second processing device 50, or other devices mentioned below can be connected between the chemical reaction assembly 21 and the energy storage unit 10, so that the flue gas exhausted by the energy storage unit 10 can first pass through the condensing device 22, the second processing device 50, or other devices mentioned below, and then be discharged to the chemical reaction assembly 21. Taking the example of a condensing device 22 connected between the chemical reaction assembly 21 and the energy storage unit 10, as shown in FIG2 , the condensing device 22 is connected to multiple energy storage units 10, the chemical reaction assembly 21 is connected to the condensing device 22, and the condensing device 22 is disposed between the energy storage unit 10 and the chemical reaction assembly 21, so that the chemical reaction assembly 21 is indirectly connected to the multiple energy storage units 10.

[0111] Such an arrangement enables the first processing device 20 to include a chemical reaction component 21 , thereby enabling the flue gas discharged from the energy storage unit 10 to undergo a chemical reaction to remove combustible components in the flue gas.

[0112] Continuing to refer to FIG. 2 , the condensing device 22 is connected to the plurality of energy storage units 10 and is used to condense electrolyte vapor in the flue gas.

[0113] It should be noted here that the flue gas discharged from the energy storage unit 10 may include combustible components such as electrolyte vapor.

[0114] The condensation device 22 is a device used to condense electrolyte vapor in the flue gas. The condensation device 22 condenses the electrolyte vapor in the flue gas into a liquid state. This prevents the liquid electrolyte from continuing to flow with the flue gas, thereby reducing the electrolyte content in the treated flue gas and effectively removing electrolytes from the flue gas.

[0115] The condensing device 22 may include an air conditioner, an air cooler, or other device capable of condensing the flue gas.

[0116] Among them, the condensing device 22 is connected to multiple energy storage units 10, so that the multiple energy storage units 10 are respectively gas-connected to the condensing device 22, so that the flue gas of the multiple energy storage units 10 can be discharged to the condensing device 22, and then the electrolyte vapor in the flue gas is condensed to remove the electrolyte in the flue gas.

[0117] Among them, the condensing device 22 and the energy storage unit 10 can achieve gas communication through the pipeline assembly 40. As an example, the condensing device 22 and the energy storage unit 10 can be connected through the exhaust branch pipe 41. Specifically, each energy storage unit 10 is connected to the exhaust branch pipe 41, and the exhaust branch pipes 41 on multiple energy storage units 10 are respectively connected to the condensing device 22, so that the condensing device 22 is connected to multiple energy storage units 10. As another example, please refer to Figure 2, the condensing device 22 and the energy storage unit 10 can also be connected through the exhaust branch pipe 41 and the exhaust main pipe 42. Specifically, each energy storage unit 10 is connected to the exhaust branch pipe 41, the exhaust branch pipes 41 on multiple energy storage units 10 are connected to the exhaust main pipe 42, and the exhaust main pipe 42 is connected to the condensing device 22, so that the condensing device 22 is connected to multiple energy storage units 10.

[0118] In some possible designs, the flue gas exhausted by the condensing device 22 can be directly discharged to the condensing device 22 through the pipe assembly 40. Alternatively, in other possible designs, the chemical reaction assembly 21 mentioned above, the second processing equipment 50 mentioned below, or other components can be connected between the condensing device 22 and the energy storage unit 10, so that the flue gas exhausted by the energy storage unit 10 can first pass through the chemical reaction assembly 21, the second processing equipment 50, or other components, and then be discharged to the condensing device 22. Taking the example of a chemical reaction assembly 21 connected between the energy storage unit 10 and the condensing device 22, the chemical reaction assembly 21 is connected to multiple energy storage units 10, the chemical reaction assembly 21 is connected to the condensing device 22, and the chemical reaction assembly 21 is disposed between the energy storage unit 10 and the condensing device 22, thereby indirectly connecting the condensing device 22 to the multiple energy storage units 10.

[0119] With such configuration, the first processing device 20 may include a condensing device 22 , which may condense electrolyte vapor in the flue gas, thereby removing the electrolyte in the flue gas and thereby removing the combustible components in the flue gas.

[0120] In some embodiments, referring to FIG. 2 and in conjunction with other figures, the first processing device 20 includes the aforementioned condensing device 22 and a chemical reaction component 21. The energy storage unit 10, the condensing device 22, and the chemical reaction component 21 are connected in sequence.

[0121] As can be understood, the piping assembly 40 includes an exhaust manifold 42 and multiple exhaust branch pipes 41, with each energy storage unit 10 connected to an exhaust branch pipe 41. The exhaust branch pipes 41 on multiple energy storage units 10 are directly connected to the condensing device 22; alternatively, the exhaust branch pipes 41 on multiple energy storage units 10 are connected to the exhaust manifold 42, which in turn is connected to the condensing device 22. Furthermore, the condensing device 22 and the chemical reaction assembly 21 are connected via the exhaust manifold 42. Thus, the energy storage units 10, condensing device 22, and chemical reaction assembly 21 are sequentially connected and communicate with each other, meaning that the condensing device 22 is positioned between the energy storage units 10 and the chemical reaction assembly 21. In this way, the flue gas discharged from the multiple energy storage units 10 can first converge at the condensing device 22, where it condenses the electrolyte vapor in the flue gas before flowing to the chemical reaction assembly 21, where it undergoes a chemical reaction, thereby removing combustible components such as carbon monoxide and hydrogen from the flue gas.

[0122] Therefore, by providing the condensing device 22 and the chemical reaction component 21 , the first processing equipment 20 can perform physical treatment and chemical treatment on the flue gas respectively, so as to effectively remove the combustible components in the flue gas.

[0123] It should be noted that the condensation device 22 is positioned between the energy storage unit 10 and the chemical reaction assembly 21 to condense the flue gas before the chemical reaction. This reduces the interference of electrolyte vapor with the chemical reaction during the flue gas reaction. This effectively improves the chemical reaction efficiency of the flue gas and, in turn, the removal of combustible components from the flue gas.

[0124] In some embodiments, referring to FIG. 2 and in conjunction with other figures, the chemical reaction assembly 21 includes a plurality of reaction devices 211 , wherein one reaction device 211 is connected to a plurality of energy storage units 10 , and the plurality of reaction devices 211 are sequentially connected to sequentially cause the combustible components in the flue gas to chemically react.

[0125] The reaction device 211 is a device for causing the combustible components in the flue gas to undergo a chemical reaction, thereby removing the combustible components in the flue gas.

[0126] The chemical reaction assembly 21 is connected to the plurality of energy storage units 10 , specifically one of the reaction devices 211 is connected to the plurality of energy storage units 10 , so that the plurality of energy storage units 10 are in gas communication with the reaction device 211 .

[0127] Such an arrangement allows the flue gas discharged from multiple energy storage units 10 to pass through multiple reaction devices 211 in sequence. In this way, the combustible components in the flue gas can undergo chemical reactions in sequence under the action of multiple reaction devices 211, thereby improving the removal effect of the combustible components in the flue gas and helping to obtain low-harm gas with poor combustibility.

[0128] In some embodiments, referring to FIG2 and other figures, the plurality of reaction devices 211 include a first reaction device 211a and a second reaction device 211b. The first reaction device 211a is at least used to reduce the combustible components in the flue gas, and the second reaction device 211b is used to burn the flue gas.

[0129] It can be understood that among the multiple reaction devices 211, two of the reaction devices 211 are respectively a first reaction device 211a and a second reaction device 211b.

[0130] The first reaction device 211a is used to cause the combustible components in the flue gas to undergo a reduction reaction so as to remove the combustible components in the flue gas.

[0131] The second reaction device 211b is used to burn the flue gas to cause the combustible components in the flue gas to undergo an oxidation reaction, thereby removing the combustible components in the flue gas.

[0132] Wherein, the first reaction device 211a is arranged between the second reaction device 211b and the energy storage unit 10, then the first reaction device 211a is connected to multiple energy storage units 10, and the second reaction device 211b is connected to the first reaction device 211a, thereby realizing that the second reaction device 211b is also indirectly connected to multiple energy storage units 10. Alternatively, the second reaction device 211b is arranged between the first reaction device 211a and the energy storage unit 10, then the second reaction device 211b is connected to multiple energy storage units 10, and the second reaction device 211b is also connected to the first reaction device 211a, thereby realizing that the first reaction device 211a is indirectly connected to multiple energy storage units 10.

[0133] By adopting the above technical solution, the combustible components in the flue gas discharged from the energy storage unit 10 can undergo oxidation reaction and combustion respectively, thereby improving the removal effect of the combustible components in the flue gas.

[0134] In some embodiments, referring to FIG2 and in conjunction with other drawings, the first reaction device 211a is connected to a plurality of energy storage units 10, and the energy storage units 10, the first reaction device 211a, and the second reaction device 211b are connected in sequence.

[0135] It can be understood that the first reaction device 211 a is disposed between the energy storage unit 10 and the second reaction device 211 b .

[0136] By adopting the above technical solution, the flue gas discharged from multiple energy storage units 10 can first pass through the first reaction device 211a, where the combustible components in the flue gas undergo a reduction reaction. It then passes through the second reaction device 211b, where the combustible components in the flue gas are burned and oxidized. This arrangement can minimize the combustible components in the flue gas before combustion, thereby reducing the possibility of explosion when the flue gas burns in the second reaction device 211b.

[0137] In addition, the condensing device 22 is disposed between the energy storage unit 10 and the chemical reaction assembly 21, specifically, between the first reaction device 211a and the energy storage unit 10. This allows the flue gas to first undergo condensation, then undergo a reduction reaction, and then burn. This can minimize the combustible components in the flue gas before combustion, thereby reducing the possibility of explosion when the flue gas burns in the second reaction device 211b.

[0138] In some embodiments, the first reaction device 211a includes a first chamber connected to the plurality of energy storage units 10 and a metal oxide. The metal oxide is disposed in the first chamber and is used to perform a reduction reaction with carbon monoxide in the flue gas.

[0139] The first chamber refers to a structure having an inner cavity. The first reaction device 211a is connected to a plurality of energy storage units 10, specifically, the first chamber is connected to the plurality of energy storage units 10, so that the plurality of energy storage units 10 are in gas communication with the first chamber respectively.

[0140] By adopting the above technical solution, the flue gas discharged from multiple energy storage units 10 can enter the first chamber, so that the carbon monoxide in the flue gas can produce a reduction reaction with the metal oxide, thereby achieving the effect of removing carbon monoxide and the effect of removing combustible components in the flue gas.

[0141] As an example, the metal oxide is high temperature copper oxide.

[0142] In some embodiments, the second reaction device 211b includes a second chamber connected to the plurality of energy storage units 10 and a lighter disposed in the second chamber for igniting the combustion smoke.

[0143] The second chamber refers to a structure having an inner cavity. The second reaction device 211b is connected to a plurality of energy storage units 10, specifically, the second chamber is connected to the plurality of energy storage units 10, so that the plurality of energy storage units 10 are respectively connected to the second chamber.

[0144] In the case where the first reaction device 211 a is disposed between the second reaction device 211 b and the energy storage unit 10 , the second chamber is connected to the first chamber, so that the second chamber is indirectly connected to the plurality of energy storage units 10 .

[0145] A fire starter is a device that can produce an open flame.

[0146] By adopting the above technical solution, the flue gas discharged from the multiple energy storage units 10 can enter the second chamber and be burned by the open flame generated by the lighter in the second chamber, thereby achieving an oxidation reaction of the combustible components in the flue gas and removing the combustible components in the flue gas. The provision of the second chamber allows the flue gas to burn in the second chamber, isolating the flue gas from the external environment during combustion, and reducing the pollution of the external environment caused by the flue gas combustion.

[0149] Such an arrangement allows the flue gas discharged from multiple energy storage units 10 to pass through multiple condensing devices 22 in sequence. In this way, the electrolyte vapor in the flue gas can be condensed in sequence under the action of multiple condensing devices 22, thereby improving the removal effect of the electrolyte in the flue gas, that is, improving the removal effect of the combustible components in the flue gas, which helps to obtain low-harm gas with poor flammability.

[0150] In some embodiments, the condensing device 22 includes a first condenser and a first water absorber.

[0154] By adopting the above technical solution, the flue gas discharged from multiple energy storage units 10 can pass through the first condenser, thereby condensing the electrolyte vapor in the flue gas into a liquid state and being absorbed by the first water absorbent member. This arrangement can reduce the electrolyte vapor in the flue gas, thereby reducing the combustible components in the flue gas.

[0155] In some embodiments, referring to FIG. 2 and in conjunction with other figures, the chemical reaction assembly 21 includes a second reaction device 211b , which is connected to multiple energy storage units 10 and is used to combust flue gas.
