[0049] In this technical solution, it is defined that the energy storage system also includes a second control valve. Specifically, the cabinet is also provided with an exhaust pressure relief port, wherein the exhaust pressure relief port is connected to the second chamber.

[0050] It is understandable that when the battery module in the second chamber is abnormal and generates combustible gas, such as carbon monoxide or hydrogen, etc., the exhaust pressure relief port can be opened by the second control valve to discharge the combustible gas in the second chamber, thereby improving the safety of the energy storage system.

[0051] Optionally, the energy storage system further includes a detection component for detecting the concentration of the combustible gas in the second chamber or the pressure in the second chamber, and when a set value is reached, causing the second control valve to open the exhaust pressure relief port to achieve active exhaust.

It is understandable that when a fire occurs in the second chamber, a fire extinguishing medium, such as a liquid medium or a gaseous medium, can be provided to the second chamber through the fire interface, thereby achieving rapid fire extinguishing of the energy storage system after the fire occurs, thereby reducing losses.

[0055] Optionally, the energy storage system further includes a pipeline, one end of which is connected to the fire protection interface, and the other end of which is connected to the fire extinguishing medium.

The air inlet baffle can separate the air inlet into a first inlet and a second inlet, the first inlet is opposite to the energy storage inverter, and the second inlet is opposite to the temperature control device.

[0062] In this technical solution, it is defined that the energy storage system also includes an air inlet baffle. Specifically, it can be understood that since the energy storage inverter and the temperature control device generate different amounts of heat during operation, the energy storage inverter and the temperature control device have different heat dissipation requirements. Generally, the power of the fan used for heat dissipation in the temperature control device is greater than the power of the fan used for heat dissipation in the energy storage inverter to meet different heat dissipation requirements.

[0063] Since the power of the fan in the temperature control device is greater than the power of the fan in the energy storage inverter, the suction force generated by the fan in the temperature control device is greater than the suction force generated by the fan in the energy storage inverter. When the energy storage inverter and the temperature control device are located in the same first chamber at the same time, the heat dissipation effect of the energy storage inverter will be affected, which may easily lead to failure of the energy storage inverter and affect the service life of the energy storage system.

[0064] The air inlet baffle separates the air inlet into a first inlet and a second inlet, wherein the first inlet is opposite to the energy storage converter, that is, part of the airflow inhaled from the first inlet can flow through the energy storage converter and then be discharged through the air outlet to achieve heat dissipation of the energy storage converter. The second inlet is opposite to the temperature control device, that is, part of the airflow inhaled from the second inlet can flow through the temperature control device and then be discharged through the air outlet to achieve heat dissipation of the temperature control device.

[0065] That is, the air inlet baffle can separate the air inlet, thereby avoiding the problem of the air intake on the energy storage inverter side being affected by the large suction force of the fan of the temperature control device, meeting the air intake requirements of the energy storage inverter and the temperature control device, effectively improving the heat dissipation effect of the energy storage system, and achieving efficient heat dissipation.

[0066] Optionally, at least a portion of the air inlet baffle extends in a horizontal direction, thereby dividing the first chamber into upper and lower air ducts. Since the energy storage inverter and the temperature control device are located in different air ducts for heat dissipation, the energy storage inverter and the temperature control device are arranged along the height direction of the cabinet.

[0067] In some technical solutions, optionally, the energy storage system also includes an air outlet baffle, which is arranged in the first chamber and close to the air outlet. The air outlet baffle can separate the air outlet into a first outlet and a second outlet. The first outlet is opposite to the energy storage inverter, and the second outlet is opposite to the temperature control device.

[0068] In this technical solution, it is defined that the energy storage system also includes an air outlet baffle. Specifically, the air outlet baffle is arranged close to the air outlet.

[0069] The air outlet baffle separates the air outlet into a first outlet and a second outlet, wherein the first outlet is opposite to the energy storage converter, that is, part of the airflow inhaled from the first inlet can flow through the energy storage converter and then be discharged through the first outlet to achieve heat dissipation of the energy storage converter. The second outlet is opposite to the temperature control device, that is, part of the airflow inhaled from the second inlet can flow through the temperature control device and then be discharged through the second outlet to achieve heat dissipation of the temperature control device.

[0070] That is, the air outlet baffle can separate the air outlet, thereby avoiding the mutual influence of the airflow on the air outlet side of the temperature control device and the energy storage inverter, further improving the heat dissipation effect of the energy storage system and achieving efficient heat dissipation.

[0071] Optionally, at least a portion of the air outlet baffle extends in a horizontal direction.

[0072] Optionally, the air outlet baffle includes an air outlet tube, and the cross-sectional shape of the air outlet tube is circular or quadrilateral.

[0101] Since the energy storage converter 120, the temperature control device 130 and the battery module 140 are arranged in sequence along the height direction of the cabinet 110, that is, the temperature control device 130 is arranged close to the battery module 140, which not only realizes the integrated design in the height direction and reduces the system footprint, but also helps to shorten the length of the liquid pipeline connecting the battery module 140 and the temperature control device 130, further simplifies the structure of the system, and thus helps to reduce the production cost of the energy storage system 100.

[0117] The other end of the fire-fighting pipeline 162 extends into the second chamber 112 , and the fire-fighting pipeline 162 is connected to at least one protective cavity, so that when the battery body catches fire, fire-fighting gas can be provided to the protective cavity through the fire-fighting pipeline 162 to play the role of emergency firefighting and improve the safety and reliability of the energy storage system 100 .

[0118] Moreover, since the fire-fighting pipeline 162 is directly connected to the protection cavity, that is, the fire-fighting gas is directly sprayed toward the battery body, it is beneficial to quickly extinguish the fire after the battery body catches fire, improve the fire-fighting efficiency, and reduce the loss.

[0119] like Figure 2 As shown, in some embodiments, optionally, the fire-fighting pipeline 162 is provided with a plurality of fire-fighting outlets 163, each fire-fighting outlet 163 is connected to a protective cavity; the fire-fighting control component 160 also includes a plurality of first control valves 164, and the plurality of first control valves 164 are arranged at the plurality of fire-fighting outlets 163 in a one-to-one correspondence.

[0122] like Figure 1 As shown, in some embodiments, optionally, the energy storage system 100 further includes a distribution box 170 , which is disposed in the third chamber 113 and electrically connected to the energy storage converter 120 .

[0123] In this embodiment, it is defined that the energy storage system 100 further includes a distribution box 170. Specifically, the distribution box 170 is electrically connected to the energy storage converter 120. It can be understood that the distribution box 170 is connected to the client. Since the third chamber 113 is arranged near the bottom of the cabinet 110, the distribution box 170 is arranged in the third chamber 113, so as to facilitate electrical wiring, signal wiring, AC side control and customer on-site wiring, etc., and improve the convenience of using the energy storage system 100.

[0124] In addition, integrating the power distribution box 170 and the fire control assembly 160 in the third chamber 113 is conducive to further improving the integration of the energy storage system 100, simplifying the overall structure, and facilitating installation and maintenance.

[0126] In this embodiment, at least part of the fire control assembly 160 and the power distribution box 170 are arranged in the horizontal direction, thereby optimizing the installation position of each electrical component in the third chamber 113, reducing the difficulty of installation and maintenance, and helping to reduce the installation and maintenance costs of the energy storage system 100. At the same time, since the power distribution box 170 and the fire control assembly 160 are arranged in the horizontal direction, it is helpful to reduce the space occupied by the entire system in the height direction, further simplify the overall structure of the system, and improve the system integration.

[0127] like Fig. 9 and Fig.11 As shown, in some embodiments, optionally, the energy storage system 100 further includes a heat preservation component 180 , which is disposed in the second chamber 112 and connected to an inner wall of the second chamber 112 .

Specifically, the thermal insulation component 180 is arranged in the second chamber 112, and the thermal insulation component 180 is connected to the inner wall of the second chamber 112, so as to insulate the second chamber 112 and reduce the heat exchange between the second chamber 112 and the external environment, which is beneficial to ensure that the battery module 140 in the second chamber 112 is at an optimal operating temperature and reduce the energy consumption of the temperature control device 130.

[0129] like Fig.10 and Fig.11 As shown, in some embodiments, optionally, the energy storage system 100 further includes a fireproof member 190 , which is disposed in the second chamber 112 and connected to an inner wall of the second chamber 112 .

[0130] In this embodiment, it is defined that the energy storage system 100 also includes a fireproof component 190. Specifically, the fireproof component 190 is arranged in the second chamber 112, and the fireproof component 190 is connected to the inner wall of the second chamber 112, so that the second chamber 112 has better fire resistance, thereby further improving the safety of the energy storage system 100.

[0131] Optionally, the energy storage system 100 includes both a fireproofing member 190 and a heat-insulating member 180. Specifically, the fireproofing member 190 is located between the inner wall of the second chamber 112 and the heat-insulating member 180. Alternatively, the heat-insulating member 180 is located between the inner wall of the second chamber 112 and the fireproofing member 190. The configuration can be made according to actual needs, so that the second chamber 112 has both heat-insulating function and fire-resistant capability.

[0132] like Figure 5 As shown, in some embodiments, optionally, the cabinet 110 is also provided with an exhaust pressure relief port 114, which is connected to the second chamber 112; the energy storage system 100 also includes a second control valve 210, which is provided at the exhaust pressure relief port 114 and is used to control the exhaust pressure relief port 114 to be opened or closed.

[0133] In this embodiment, it is defined that the energy storage system 100 further includes a second control valve 210 . Specifically, the cabinet 110 is further provided with an exhaust pressure relief port 114 , wherein the exhaust pressure relief port 114 is in communication with the second chamber 112 .

[0134] It is understandable that when the battery module 140 in the second chamber 112 is abnormal and generates combustible gas, such as carbon monoxide or hydrogen, the second control valve 210 can be used to open the exhaust pressure relief port 114 to discharge the combustible gas in the second chamber 112, thereby improving the safety of the energy storage system 100.

[0135] Optionally, the energy storage system 100 further includes a detection component for detecting the concentration of the combustible gas in the second chamber 112 or the pressure in the second chamber 112, and when a set value is reached, the second control valve 210 opens the exhaust pressure relief port 114 to achieve active exhaust.

[0137] Optionally, the exhaust and pressure relief port 114 includes an exhaust port and a pressure relief port, and the second chamber 112 is connected to the exhaust port and the pressure relief port; the second control valve 210 includes a first valve body and a second valve body, the first valve body is arranged at the exhaust port, and the second valve body is arranged at the pressure relief port. In other words, the exhaust port and the first valve body are used for active exhaust, and the pressure relief port and the second valve body are used for active pressure relief. The specific settings can be made according to actual needs.

[0138] Optionally, the cabinet 110 is further provided with a fire interface, which is connected to the second chamber 112. It is understandable that when a fire occurs in the second chamber 112, a fire extinguishing medium, such as a liquid medium or a gaseous medium, can be provided to the second chamber 112 through the fire interface, thereby realizing rapid fire extinguishing of the energy storage system 100 after the fire occurs, thereby reducing losses.

[0139] Optionally, the energy storage system 100 further includes a pipeline, one end of which is connected to the fire protection interface, and the other end of which is connected to the fire extinguishing medium.

[0140] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, optionally, the energy storage system 100 also includes a base 220, which is arranged at the bottom of the cabinet 110; wherein the base 220 is provided with a first interface 221, and the first interface 221 is used for hoisting the energy storage system 100; and / or the base 220 is provided with a second interface 222, and the second interface 222 is used for grounding; and / or the base 220 is provided with a third interface 223, and the third interface 223 is used for hoisting and forklift transportation of the energy storage system 100.

[0141] In this embodiment, it is defined that the energy storage system 100 further includes a base 220 . Specifically, the base 220 is disposed at the bottom of the cabinet 110 , thereby providing reliable support for the cabinet 110 .

[0142] The base 220 is provided with a first interface 221 . Specifically, the first interface 221 is used for hoisting the energy storage system 100 .

[0143] The base 220 is provided with a second interface 222 . Specifically, the second interface 222 is used for grounding to improve the safety of the energy storage system 100 .

[0144] The base 220 is provided with a third interface 223 , and the third interface 223 is used for hoisting and forklift transportation of the energy storage system 100 .

[0145] Optionally, the base 220 is further provided with a fixed foundation connection port 224 for fixedly connecting to the ground to enhance the earthquake resistance of the energy storage system 100 .

[0146] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the cabinet 110 is also provided with an air inlet 115 and an air outlet 116, and the first chamber 111 is connected to the air inlet 115 and the air outlet 116; the energy storage system 100 also includes an air inlet baffle 230, which is arranged in the first chamber 111 and close to the air inlet 115. The air inlet baffle 230 can separate the air inlet 115 into a first inlet 240 and a second inlet 250, the first inlet 240 is opposite to the energy storage inverter 120, and the second inlet 250 is opposite to the temperature control device 130.

[0147] In this embodiment, it is defined that the energy storage system 100 also includes an air inlet baffle 230. Specifically, it can be understood that since the energy storage inverter 120 and the temperature control device 130 generate different amounts of heat during operation, the energy storage inverter 120 and the temperature control device 130 have different heat dissipation requirements. Generally, the power of the fan used for heat dissipation in the temperature control device 130 is greater than the power of the fan used for heat dissipation in the energy storage inverter 120 to meet different heat dissipation requirements.

[0148] Since the power of the fan in the temperature control device 130 is greater than the power of the fan in the energy storage inverter 120, the suction force generated by the fan in the temperature control device 130 is greater than the suction force generated by the fan in the energy storage inverter 120. When the energy storage inverter 120 and the temperature control device 130 are both located in a first chamber 111, the heat dissipation effect of the energy storage inverter 120 will be affected, which may easily cause failure of the energy storage inverter 120 and affect the service life of the energy storage system 100.

[0149] The air inlet baffle 230 divides the air inlet 115 into a first inlet 240 and a second inlet 250, wherein the first inlet 240 is opposite to the energy storage converter 120, that is, part of the airflow inhaled from the first inlet 240 can flow through the energy storage converter 120 and be discharged through the air outlet 116 to achieve heat dissipation of the energy storage converter 120. The second inlet 250 is opposite to the temperature control device 130, that is, part of the airflow inhaled from the second inlet 250 can flow through the temperature control device 130 and be discharged through the air outlet 116 to achieve heat dissipation of the temperature control device 130.

[0150] That is, the air inlet baffle 230 can separate the air inlet 115, thereby avoiding the problem of the air intake on the side of the energy storage inverter 120 being affected by the large suction force of the fan of the temperature control device 130, meeting the respective air intake requirements of the energy storage inverter 120 and the temperature control device 130, effectively improving the heat dissipation effect of the energy storage system 100, and achieving efficient heat dissipation.

[0151] Optionally, at least a portion of the air inlet baffle 230 extends in a horizontal direction, thereby dividing the first chamber 111 into two upper and lower air ducts. Since the energy storage inverter 120 and the temperature control device 130 are located in different air ducts for heat dissipation, the energy storage inverter 120 and the temperature control device 130 are arranged along the height direction of the cabinet 110.

[0152] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the energy storage system 100 also includes an air outlet baffle 260, which is disposed in the first chamber 111 and close to the air outlet 116. The air outlet baffle 260 can separate the air outlet 116 into a first outlet 270 and a second outlet 280. The first outlet 270 is opposite to the energy storage inverter 120, and the second outlet 280 is opposite to the temperature control device 130.

[0153] In this embodiment, it is defined that the energy storage system 100 further includes an air outlet baffle 260 . Specifically, the air outlet baffle 260 is disposed close to the air outlet 116 .

[0154] The air outlet baffle 260 divides the air outlet 116 into a first outlet 270 and a second outlet 280, wherein the first outlet 270 is opposite to the energy storage converter 120, that is, part of the airflow inhaled from the first inlet 240 can flow through the energy storage converter 120 and then be discharged through the first outlet 270 to achieve heat dissipation of the energy storage converter 120. The second outlet 280 is opposite to the temperature control device 130, that is, part of the airflow inhaled from the second inlet 250 can flow through the temperature control device 130 and then be discharged through the second outlet 280 to achieve heat dissipation of the temperature control device 130.

[0155] That is, the air outlet baffle 260 can separate the air outlet 116, thereby preventing the airflows on the air outlet side of the temperature control device 130 and the energy storage converter 120 from affecting each other, further improving the heat dissipation effect of the energy storage system 100 and achieving efficient heat dissipation.

[0156] Optionally, at least a portion of the air outlet baffle 260 extends in the horizontal direction.

[0157] Optionally, the air outlet baffle 260 includes an air outlet tube, and the cross-sectional shape of the air outlet tube is circular or quadrilateral.

[0158] In a specific embodiment, the energy storage system 100 is divided into upper and lower compartments with spatial isolation.

The fire integrated control box integrates fire control devices and fire cylinders 161. Fire gas enters each layer of battery modules (battery module 140) through fire pipelines 162 to play an emergency fire fighting role. The fire pipeline 162 integrates a puncture valve or solenoid valve (first control valve 164) for fire gas control to accurately protect each battery module 141.

[0160] The power distribution control box (distribution box 170) is placed at the bottom to facilitate electrical wiring, signal wiring, AC side control and customer on-site wiring.

[0161] Insulation cotton (insulation component 180) is arranged on the upper, lower, front, rear and side walls of the liquid cooling warehouse (second chamber 112) to insulate the system and reduce energy consumption, or fireproof panels (fireproof component 190) are arranged to provide fire resistance.

[0162] The liquid cooler (temperature control device 130) is placed on the bottom slide rail of the upper air cooling bin (first chamber 111) to heat or cool the liquid flowing through the battery module 141 through the liquid cooling pipeline, so that the battery is always at the optimal operating temperature state, and the temperature control function is achieved through front airflow and rear air outlet.

[0163] The high-voltage box 150 and the energy storage inverter 120 are vertically stacked above the liquid cooler (temperature control device 130). The high-voltage box 150 and the energy storage inverter 120 can be integrated or separate modules. The energy storage inverter 120 realizes self-cooling through front air intake and rear air exhaust. Air duct partitions (air inlet partition 230 and air outlet partition 260) are arranged at the front and rear of the air cooling chamber (first chamber 111) to form independent air inlet and outlet channels for the liquid cooler (temperature control device 130) and the energy storage inverter 120.

[0164] A forced ventilation device and an explosion relief device (a second control valve 210 and an exhaust pressure relief port 114 ) are provided at the rear of the cabinet 110 .

[0165] A water fire-fighting interface is provided at the rear of the cabinet 110 , and the interface may be in the form of a pipeline or a standard fire-fighting interface.
