[0072] An energy storage power station usually includes multiple energy storage units, which can be energy storage cabinets, energy storage containers, etc.

[0073] It is inevitable that the energy storage unit will experience thermal runaway during use, which will generate a large amount of smoke. The smoke generated by the energy storage unit during thermal runaway is very high temperature and high pressure, and it is easy to explode after accumulation.

[0074] Therefore, in some cases, each energy storage unit is generally equipped with a flue gas treatment device, and each flue gas treatment device collects and treats the flue gas discharged 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.

[0075] Based on the above considerations, the embodiment of the present application provides an energy storage system and an energy storage power station, which connects multiple energy storage units by setting a first processing device so that the first processing device can receive the flue gas generated by multiple energy storage units when they are in thermal runaway, and remove the combustible cost in the flue gas to obtain low-harm gas, that is, the first processing device can process the flue gas of multiple energy storage units.

The housing 112 is a structure having a receiving space 11201 therein, and the receiving space 11201 of the housing 112 is used to receive the battery cells 111.

[0088] See also Figure 2 , and combined with other drawings. Figure 2 Schematic diagram of an energy storage system 100 provided in some embodiments of the present application. The energy storage system 100 provided in the embodiment 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 the first processing device 20 is used to receive the flue gas discharged from the plurality of energy storage units 10 and remove the combustible components in the flue gas.

[0089] The energy storage unit 10 refers to a unit having an energy storage function, and 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.

[0090] 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.

[0091] As an example, the first processing device 20 can remove combustible components such as carbon monoxide and hydrogen in the flue gas.

[0092] 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 respectively in gas communication with the first processing device 20, so that the first processing device 20 can receive the flue gas discharged from the plurality of energy storage units 10. In this way, the flue gas discharged 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-harm gas.

[0093] The energy storage system 100 provided in the embodiment of the present application is provided with a first processing device 20 connected to a plurality of energy storage units 10, so that the first processing device 20 can receive the flue gas generated when the plurality of energy storage units 10 are in thermal runaway, and remove the combustible cost in the flue gas to obtain low-harm gas, that is, the first processing device 20 can process the flue gas of a plurality of energy storage units 10. Such a configuration can reduce the cost of the energy storage system 100 and improve the economic efficiency of the energy storage system 100.

[0094] It should be noted that, in some cases, the flue gas discharged when the energy storage unit 10 is in thermal runaway is only inerted to reduce the possibility of explosion of the flue gas. However, since the combustible components in the flue gas still exist, the energy storage system 100 still has a high possibility of explosion. The energy storage unit 10 provided in the embodiment of the present application removes the combustible components in the flue gas through the first processing device 20 to obtain a low-harm gas with very few combustible components, which can reduce the possibility of explosion of the energy storage system 100.

[0095] In some embodiments, please refer to Figure 2 , and in combination with other drawings. 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.

[0096] Specifically, the pipeline assembly 40 may include a plurality of exhaust pipes 41, and each energy storage unit 10 is connected with 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 the plurality of energy storage units 10 through the exhaust pipe 41.

[0097] In some possible designs, one 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, the first processing device 20 and the energy storage unit 10 are gas-connected 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.

[0098] Or, in some other possible designs, such as Figure 2As shown, the pipeline assembly 40 may also include an exhaust main pipe 42, the exhaust branch pipes 41 on the multiple energy storage units 10 are connected to the exhaust main pipe 42, and the exhaust main pipe 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 through the exhaust main pipe 42. In this way, the first processing device 20 and the energy storage unit 10 are gas-connected through the exhaust branch pipes 41 and the exhaust main pipe 42, so that the flue gas discharged from the multiple energy storage units 10 can be gathered to the exhaust main pipe 42 through their respective exhaust branch pipes 41, and then discharged to the first processing device 20 through the exhaust main pipe 42.

[0099] The exhaust branch pipe 41 and the exhaust main pipe 42 both refer to pipes that can be used to pass the flue gas.

[0100] In some embodiments, see Figure 2 , and in combination with other drawings. The first processing equipment 20 includes at least one of a chemical reaction component 21 and a condensation device 22 .

[0101] See also Figure 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.

[0102] The chemical reaction component 21 is a component used to make the combustible components in the flue gas undergo a chemical reaction. The chemical reaction component 21 makes the combustible components in the flue gas undergo a chemical reaction so that the combustible components in the flue gas are absorbed or reacted, thereby achieving a removal effect of the combustible components in the flue gas, and making the flue gas processed into low-harm gas.

[0103] 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 removal effect on the carbon monoxide.

[0104] 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.

[0105] Among them, the chemical reaction component 21 is connected to multiple energy storage units 10, so that the multiple energy storage units 10 are gas-connected to the chemical reaction component 21 respectively, 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.

[0106] The chemical reaction assembly 21 and the energy storage unit 10 can be gas-connected through the pipeline assembly 40. As an example, the chemical reaction assembly 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 assembly 21, so that the chemical reaction assembly 21 is connected to multiple energy storage units 10. As another example, please refer to Figure 2 The chemical reaction assembly 21 and the energy storage unit 10 may also be connected via an exhaust branch pipe 41 and an exhaust main pipe 42. Specifically, each energy storage unit 10 is connected to an exhaust branch pipe 41, and 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 assembly 21, so that the chemical reaction assembly 21 is connected to multiple energy storage units 10.

[0107] In some possible designs, the flue gas discharged from the energy storage unit 10 can be directly discharged to the chemical reaction component 21 through the pipeline component 40. Alternatively, in other possible designs, the condensing device 22, the second processing device 50 or other devices mentioned below can be connected between the chemical reaction component 21 and the energy storage unit 10, so that the flue gas discharged from 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 component 21. Taking the example of the condensing device 22 connected between the chemical reaction component 21 and the energy storage unit 10, as shown in FIG. Figure 2 As shown, the condensing device 22 is connected to multiple energy storage units 10, the chemical reaction component 21 is connected to the condensing device 22, and the condensing device 22 is arranged between the energy storage unit 10 and the chemical reaction component 21, so that the chemical reaction component 21 is indirectly connected to the multiple energy storage units 10.

[0108] 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.

[0109] Please continue reading Figure 2 The condensing device 22 is connected to the plurality of energy storage units 10 and is used to condense the electrolyte vapor in the flue gas.

[0110] It should be noted here that the flue gas discharged from the energy storage unit 10 may include combustible components such as electrolyte vapor.

[0111] The condensation device 22 refers to a device for condensing electrolyte vapor in the flue gas. The condensation device 22 condenses the electrolyte vapor in the flue gas so that the electrolyte vapor is condensed into a liquid state. In this way, the liquid electrolyte will not continue to flow with the flue gas, so that the electrolyte content in the treated flue gas can be reduced, thereby achieving the effect of removing the electrolyte in the flue gas.

[0112] The condensing device 22 may include an air conditioner, a cold air blower or other device capable of condensing the flue gas.

[0113] Among them, the condensing device 22 is connected to multiple energy storage units 10, so that the multiple energy storage units 10 are gas-connected to the condensing device 22 respectively, 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.

[0114] The condensing device 22 and the energy storage unit 10 can be gas-connected through the pipe 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 may also be connected via an exhaust branch pipe 41 and an exhaust main pipe 42. Specifically, each energy storage unit 10 is connected to an exhaust branch pipe 41, and 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.

[0115] In some possible designs, the flue gas discharged from 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 discharged from 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 the 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 arranged between the energy storage unit 10 and the condensing device 22, so that the condensing device 22 is indirectly connected to the multiple energy storage units 10.

[0116] In this configuration, the first processing device 20 may include a condensing device 22, which may condense electrolyte vapor in the flue gas, thereby removing electrolyte from the flue gas and removing combustible components from the flue gas.

[0117] In some embodiments, see Figure 2 , and in combination with other drawings. The first processing device 20 includes the above-mentioned condensing device 22 and the chemical reaction component 21. The energy storage unit 10, the condensing device 22 and the chemical reaction component 21 are connected in sequence.

[0118] It can be understood that the pipeline assembly 40 includes an exhaust main pipe 42 and a plurality of exhaust branch pipes 41, and each energy storage unit 10 is connected to an exhaust branch pipe 41. The exhaust branch pipes 41 on the plurality of energy storage units 10 are directly connected to the condensing device 22; or, the exhaust branch pipes 41 on the plurality of 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. Moreover, the condensing device 22 and the chemical reaction component 21 are connected through the exhaust main pipe 42. Based on this, the energy storage unit 10, the condensing device 22 and the chemical reaction component 21 are connected in sequence and communicated, that is, the condensing device 22 is arranged between the energy storage unit 10 and the chemical reaction component 21. In this way, the flue gas discharged from the plurality of energy storage units 10 can first converge to the condensing device 22, and after the condensing device 22 condenses the electrolyte vapor in the flue gas, it flows to the chemical reaction component 21 to perform a chemical reaction under the action of the chemical reaction component 21, thereby removing combustible components such as carbon monoxide and hydrogen in the flue gas.

[0119] Therefore, by providing the condensing device 22 and the chemical reaction component 21, the first processing equipment 20 can perform physical processing and chemical processing on the flue gas respectively, so as to effectively remove the combustible components in the flue gas.

[0120] It should be noted that the condensation device 22 is disposed between the energy storage unit 10 and the chemical reaction component 21, so that the flue gas is first condensed and then chemically reacted, so that during the chemical reaction of the flue gas, the interference of the electrolyte vapor on the chemical reaction can be reduced. In this way, the chemical reaction effect of the flue gas can be effectively improved, and the removal effect of the combustible components in the flue gas can be improved.

[0121] In some embodiments, see Figure 2 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 connected in sequence to sequentially react the combustible components in the flue gas.

[0122] 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.

[0123] The chemical reaction assembly 21 is connected to a plurality of energy storage units 10 , specifically, one of the reaction devices 211 is connected to a plurality of energy storage units 10 , so that the plurality of energy storage units 10 are in gas communication with the reaction device 211 .

[0124] Such arrangement enables 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.

[0125] In some embodiments, see Figure 2 , and in combination with other drawings. 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] Wherein, the first reaction device 211a is disposed between the second reaction device 211b and the energy storage unit 10, then the first reaction device 211a is connected to a plurality of 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 a plurality of energy storage units 10. Alternatively, the second reaction device 211b is disposed between the first reaction device 211a and the energy storage unit 10, then the second reaction device 211b is connected to a plurality of 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 a plurality of energy storage units 10.

[0130] 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.

[0131] In some embodiments, see Figure 2, and in combination 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.

[0132] It can be understood that the first reaction device 211a is disposed between the energy storage unit 10 and the second reaction device 211b.

[0133] By adopting the above technical solution, the flue gas discharged from the multiple energy storage units 10 can first pass through the first reaction device 211a, so that the combustible components in the flue gas are first reduced under the action of the first reaction device 211a, and then pass through the second reaction device 211b, so that the combustible components in the flue gas are burned under the action of the second reaction device 211b to perform an oxidation reaction. In this way, the combustible components in the flue gas can be reduced as much as possible before the flue gas is burned, thereby reducing the possibility of explosion when the flue gas is burned in the second reaction device 211b.

[0134] In addition, the condensing device 22 is disposed between the energy storage unit 10 and the chemical reaction assembly 21, specifically, the condensing device 22 is disposed between the first reaction device 211a and the energy storage unit 10. In this way, the flue gas is first condensed, then reduced, and then burned, so that the combustible components in the flue gas can be reduced as much as possible before the flue gas is burned, thereby reducing the possibility of explosion when the flue gas burns in the second reaction device 211b.

[0135] In some embodiments, the first reaction device 211a includes a first chamber and a metal oxide. The first chamber is connected to a plurality of energy storage units 10. The metal oxide is disposed in the first chamber and is used to perform a reduction reaction with carbon monoxide in the flue gas.

[0136] 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 a plurality of energy storage units 10, so that the plurality of energy storage units 10 are respectively in gas communication with the first chamber.

[0137] 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.

[0138] As an example, the metal oxide is high temperature copper oxide.

[0139] In some embodiments, the second reaction device 211b includes a second chamber and an igniter. The second chamber is connected to a plurality of energy storage units 10. The igniter is disposed in the second chamber and is used to ignite and burn smoke.

[0140] 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 a plurality of energy storage units 10, so that the plurality of energy storage units 10 are respectively connected to the second chamber.

[0141] In which, when 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 .

[0142] A fire starter is a device that can produce an open flame.

[0143] By adopting the above technical solution, the smoke discharged from the multiple energy storage units 10 can enter the second chamber and burn in the second chamber through the open flame generated by the lighter, thereby realizing the oxidation reaction of the combustible components in the smoke to remove the combustible components in the smoke. The setting of the second chamber allows the smoke to burn in the second chamber, so that the smoke can be isolated from the external environment during combustion, thereby improving the pollution of the smoke combustion to the external environment.

[0144] In some embodiments, see Figure 2 , and combined with other drawings. There are multiple condensing devices 22, one condensing device 22 is connected to multiple energy storage units 10, and multiple condensing devices 22 are connected in sequence to condense electrolyte vapor in the flue gas in sequence.

[0145] One of the condensing devices 22 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 condensing device 22 .

[0146] Such arrangement enables the flue gas discharged from the multiple energy storage units 10 to pass through the multiple condensing devices 22 in sequence. Thus, the electrolyte vapor in the flue gas can be condensed in sequence under the action of the 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, and helping to obtain low-harm gas with poor combustibility.

[0147] In some embodiments, the condensing device 22 includes a first condenser and a first water absorber.

[0151] By adopting the above technical solution, the flue gas discharged from the multiple energy storage units 10 can pass through the first condenser, so that the electrolyte vapor in the flue gas is condensed into liquid and absorbed by the first water absorbent. This arrangement can reduce the electrolyte vapor in the flue gas, thereby reducing the combustible components in the flue gas.

[0152] In some embodiments, see Figure 2 , and in combination with other drawings. The chemical reaction assembly 21 includes a second reaction device 211b, which is connected to a plurality of energy storage units 10 and is used to burn flue gas.

[0155] The energy storage unit 10, the second reaction device 211b and the cooling device are connected in sequence, so that the energy storage unit 10, the second reaction device 211b and the condensing device 22 are connected in sequence.

[0156] By adopting the above technical solution, the flue gas discharged from the energy storage unit 10 can first pass through the second reaction device 211b to achieve combustion, thereby removing the combustible components in the flue gas during the combustion process; then, the flue gas passes through the cooling device to cool the flue gas obtained after combustion, thereby reducing the temperature of the flue gas to reduce the possibility of explosion of the flue gas.

The energy storage system 100 further includes an inerting device 30, the energy storage unit 10, the first processing equipment 20 and the inerting device 30 are connected in sequence, and the inerting device 30 is used for inerting the flue gas.
