[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0041] Firstly, this application provides an energy storage system, which can specifically be a device or system capable of storing energy and releasing it when needed. In modern energy networks, energy storage systems can integrate renewable energy sources such as solar and wind power, thereby helping to balance supply and demand, improve grid stability, and support the efficient operation of the electricity market.

[0042] Please combine Figure 1 The energy storage system may include a container 100, which may be a shipping container, and may be used to integrate the energy storage, power conversion and other components of the energy storage system.

[0043] Please combine Figure 3 The enclosure 100 contains isolated battery compartment 107 and electrical compartment 109. Specifically, the isolation between battery compartment 107 and electrical compartment 109 means that there is no ventilation between them, or that there is no gas exchange between them. Therefore, gas in battery compartment 107 will not directly enter electrical compartment 109, and vice versa. This prevents the spread of fire or flammable gas from battery compartment 107 to electrical compartment 109, and vice versa.

[0044] Please combine Figure 8 and Figure 10 The energy storage system also includes a fire suppression system 300, which may include an exhaust fan 301, a first air damper 303, and a second air damper 305 installed on the housing 100. The first air damper 303 may include an A-60 fire barrier. The second air damper 305 may also include an A-60 fire barrier. The exhaust fan 301 is used to exhaust the gas inside the battery compartment 107 to the outside of the energy storage system. In other words, the exhaust fan 301 exhausts the gas inside the battery compartment 107. Please refer to... Figure 8 and Figure 9 Both the first air damper 303 and the second air damper 305 can be opened or closed, and their opening degrees can be adjusted to facilitate gas exchange between the battery compartment 107 and the outside of the energy storage system. When the first air damper 303 is open, gas exchange between the battery compartment 107 and the outside of the energy storage system can be achieved through the first air damper 303. When the first air damper 303 is closed, gas exchange between the battery compartment 107 and the outside of the energy storage system cannot be achieved through the first air damper 303. Please refer to... Figure 10 and Figure 11 When the second air damper 305 is open, the battery compartment 107 can exchange gases with the outside of the energy storage system through the second air damper 305; when the second air damper 305 is closed, the battery compartment cannot exchange gases with the outside of the energy storage system through the second air damper 305.

[0045] Please combine Figure 1 In some embodiments, Figure 1 The diagram illustrates the length, width, and height of the energy storage system. The length of the energy storage system corresponds to the length of the enclosure 100, the width corresponds to the width of the enclosure 100, and the height corresponds to the height of the enclosure 100. The enclosure 100 can be a cuboid with a length of 6058 mm, a width of 2438 mm, and a height of 2591 mm. The enclosure 100 can be equipped with six doors 903, which can be configured as doors with a fire resistance rating of A-60.

[0046] In some embodiments, insulation cotton can be laid around the enclosure 100 to give the energy storage system a better fire resistance and heat insulation effect.

[0047] In some embodiments, the exhaust fan 301 and the first damper 303 can be configured to be linked. For example, when the exhaust fan 301 starts, the control system simultaneously sends a signal to open the first damper 303, ensuring that air can be smoothly exhausted. Conversely, when the exhaust fan 301 stops running, the first damper 303 automatically closes to prevent backflow of external air. This linkage can be achieved through electrical control, pneumatic control, or mechanical connection. This ensures that the first damper 303 opens promptly when exhaust is needed, reducing wind resistance and improving the working efficiency of the exhaust fan. Simultaneously, when the exhaust fan 301 stops running, the closing of the first damper 303 prevents air backflow and maintains the stability of indoor air.

[0048] In some embodiments, the exhaust fan 301 is used to discharge the gas inside the battery compartment 107 to the outside of the energy storage system through the first air damper 303. Please refer to... Figure 9The exhaust port 3010 of the exhaust fan 301 can be connected to the outside of the energy storage system, and the air inlet of the exhaust fan 301 can be connected to the air outlet of the first air damper 303. Please refer to... Figure 11 The air inlet 3030 of the first air damper is connected to the battery compartment 107. In this way, the gas in the battery compartment 107 enters the air inlet 3030 of the first air damper, passes through the air outlet of the first air damper 303 and the air inlet of the exhaust fan 301, and is discharged through the exhaust outlet 3010 of the exhaust fan.

[0049] In some embodiments, the first air damper 303 and the second air damper 305 can be opened simultaneously, and the first air damper 303 and the second air damper 305 can also be closed simultaneously.

[0050] When the exhaust fan 301 is turned off and the first air damper 303 and the second air damper 305 are opened simultaneously, natural ventilation of the battery compartment 107 can be maintained, meaning that outside air and gas inside the battery compartment can be exchanged naturally. The first air damper 303 can serve as both an inlet for outside air and an outlet for gas inside the battery compartment, and the second air damper 305 can also serve as both an inlet for outside air and an outlet for gas inside the battery compartment. In some embodiments, when the battery compartment 107 is in normal operating condition (no fire occurs, and there is no abnormality in the presence of combustible gas inside the battery compartment), the exhaust fan 301 can be turned off, and the first air damper 303 and the second air damper 305 can be opened simultaneously to maintain natural ventilation of the battery compartment 107.

[0051] In some embodiments, when the battery compartment 107 is in the first state, the exhaust fan 301 operates, and the first damper 303 and the second damper 305 open. The first damper 303 cooperates with the exhaust fan 301 to exhaust at least a portion of the gas inside the battery compartment 107, while external gas enters the battery compartment 107 through the second damper 305. The battery compartment 107 being in the first state may indicate the presence of an abnormality in combustible gas, meaning a certain concentration of combustible gas exists within the battery compartment 107, posing a safety hazard. Specifically, the combustible gas may include carbon monoxide, methane, hydrogen, etc. When the battery compartment 107 is in the first state, the exhaust fan 301 and the first damper 303 work together to exhaust the gas inside the battery compartment 107, thereby accelerating the gas exchange between the battery compartment 107 and the external environment of the energy storage system, rapidly reducing the concentration of combustible gas inside the battery compartment 107, and allowing the battery compartment 107 to return to normal operation, preventing the accumulation of thermal runaway gas that could lead to an explosion of the battery compartment 107.

[0052] Please combine Figure 3 , Figure 4 as well as Figure 8In some embodiments, the housing 100 includes a first side wall 111 and a partition 103. The partition 103 and the first side wall 111 form a battery compartment 107. The exhaust fan 301 and the first air damper 303 can both be fixed to the first side wall 111 to facilitate the coordinated operation between the exhaust fan 301 and the first air damper 303 for exhausting the gas in the battery compartment 107.

[0053] In these embodiments, the first damper 303 can be used to control the flow rate and pressure of gas entering or exiting the battery compartment 107. By adjusting the opening of the first damper 303, it can be ensured that the gas entering or exiting meets the requirements, and the intake or exhaust volume can be controlled to meet the different operating conditions of the system. The second damper 305 can be used to control the flow rate and pressure of gas entering or exiting the battery compartment 107. By adjusting the opening of the second damper 305, it can be ensured that the gas entering or exiting meets the requirements, and the intake or exhaust volume can be controlled to meet the different operating conditions of the system. The first damper 303 can be used in conjunction with the exhaust fan 301 to regulate the gas flow rate in the battery compartment 107. By adjusting the opening of the first damper 303, the gas flow rate output by the exhaust fan 301 can be changed. In some embodiments, the first damper 303 can also serve as a start / stop control device for the exhaust fan 301. When the first damper 303 is closed, it prevents gas flow, thereby stopping the exhaust fan 301; when the first damper 303 is open, it allows gas flow and starts the exhaust fan 301.

[0054] Please combine Figure 3 as well as Figure 8 In some embodiments, the first air damper 303 may be located above the exhaust fan 301 and positioned near the top of the battery compartment 107. Thus, the air inlet 3030 of the first air damper is positioned near the top of the battery compartment 107, and the air outlet of the first air damper 303 may be located below the air inlet of the first air damper 303 and connected to the air inlet of the exhaust fan 301 located below the first air damper 303. The exhaust outlet 3010 of the exhaust fan may be located below the air inlet of the exhaust fan 301. In this way, gas inside the battery compartment 107 enters the air inlet 3030 of the first air damper located at the top of the battery compartment 107, flows downwards, passes through the air outlet of the first air damper 303 and the air inlet of the exhaust fan 301, and is discharged through the exhaust outlet 3010 of the exhaust fan. Since most combustible gases are less dense than air, such as common combustible gases like hydrogen, methane, carbon monoxide, ethylene, and acetylene, they tend to concentrate at the top of the battery compartment 107. In these embodiments, the first air damper 303 is located above the exhaust fan 301 to facilitate the full discharge of combustible gases concentrated at the top of the battery compartment 107.

[0055] Please combine Figure 3 as well as Figure 10 In some embodiments, the energy storage system further includes a mounting box 401, which is mainly used for installing and fixing the exhaust fan 301 and the first damper 303. Please refer to... Figure 9 as well as Figure 11 A first opening 114 can be provided on the first side wall 111. The first opening 114 and the battery compartment 107 can be arranged along the length direction of the energy storage system. That is, the battery compartment 107 can be connected to the outside of the energy storage system through the first opening 114. The mounting box 401 is provided with a connected mounting cavity 403, a second opening 405 and a third opening 407. The second opening 405 and the mounting cavity 403 can be arranged along the length direction of the energy storage system, and the third opening 407 and the mounting cavity 403 can be arranged along the height direction of the energy storage system. The mounting box 401 is located inside the battery compartment 107. The exhaust fan 301 and the first air damper 303 are installed in the mounting cavity 403 of the mounting box 401. That is, the exhaust fan 301 and the first air damper 303 are both located inside the battery compartment 107. The mounting cavity 403, the second opening 405, and the third opening 407 are connected. The second opening 405 is connected to the first opening 114. The exhaust fan 301 and the first air damper 303 are both installed in the mounting cavity 403, so that the exhaust fan 301 and the first air damper 303 are connected to the outside of the energy storage system through the second opening 405 and the first opening 114.

[0056] Please combine Figure 10 as well as Figure 11 The third opening 407 is located near the top of the battery compartment 107, and the first air damper 303 is located near the third opening 407. The air inlet 3030 of the first air damper can also be located near the third opening 407. The third opening 407 is located near the top of the battery compartment 107, and the air inlet 3030 of the first air damper can exchange gases with the battery compartment 107 through the third opening 407, venting the gas inside the battery compartment 107 to the outside of the energy storage system. In some embodiments, the air inlet 3030 of the first air damper can be directly opposite the third opening 407. The exhaust port 3010 of the exhaust fan vents the gas inside the battery compartment 107 through the first opening 114.

[0057] Please combine Figure 3 In some embodiments, the housing 100 further includes a second sidewall 113, which is located on the side of the partition 103 opposite to the first sidewall 111. The partition 103 and the second sidewall 113 form the aforementioned electrical compartment 109. Thus, the battery compartment 107 and the electrical compartment 109 are located on opposite sides of the partition 103. In some embodiments, the housing 100 can be a cuboid, with the battery compartment 107 and the electrical compartment 109 arranged along the length of the housing 100.

[0058] Please combine Figure 10The second air damper 305 is installed on the top of the electrical compartment 109. The second air damper 305 may include a first end 3051 and a second end 3053 arranged opposite to each other. The first end 3051 is installed on the partition 103 for communicating with the battery compartment 107, and the second end 3053 is installed on the second side wall 113 for communicating with the outside of the housing 100. The outer periphery of the first end 3051 and the partition 103 can be sealed, for example, by using fireproof putty to prevent gas exchange between the battery compartment 107 and the electrical compartment 109. The first end 3051 and the second end 3053 can be arranged along the length of the housing 100, so that the second air damper 305 can be made shorter, enabling faster gas exchange between the battery compartment 107 and the outside of the energy storage system.

[0059] In these embodiments, a second air damper 305 is installed in the electrical compartment 109. Its first end 3051 connects to the battery compartment 107, and its second end 3053 connects to the outside of the energy storage system, allowing gas exchange between the battery compartment 107 and the outside of the energy storage system. When the exhaust fan 301 and the first air damper 303 work in conjunction, the first air damper 303 and the exhaust fan 301 are typically used to exhaust gas from the battery compartment 107, while the second air damper 305 is typically used to allow external gas to enter the battery compartment 107. Thus, gas from outside the energy storage system enters the battery compartment 107 through the second air damper 305, and gas inside the battery compartment 107 can be exhausted to the outside of the energy storage system after passing through the first air damper 303 and the exhaust fan 301. Installing the second air damper 305 on the top of the electrical compartment 109 fully utilizes the top space of the electrical compartment 109, allowing the battery compartment 107 to accommodate more battery packs and increasing the energy density of the energy storage system.

[0060] Please combine Figure 16 In some embodiments, the second sidewall 113 may be provided with ventilation louvers 905 for ventilating the electrical compartment.

[0061] In some embodiments, the first damper 303 may be provided with a filter screen for filtering dust, and the second damper 305 may be provided with a filter screen for filtering dust.

[0062] Please combine Figure 1 as well as Figure 3 In some embodiments, the housing 100 further includes a top wall 115 and a bottom wall 116 disposed opposite to each other, with a partition 103 disposed between the top wall 115 and the bottom wall 116. Please refer to... Figure 6The fire protection system 300 also includes a detector 302, which is located in the battery compartment 107 and installed on the top wall 115. When the detector 302 detects the presence of combustible gas, it can determine that the battery compartment 107 is in a first state. In some embodiments, the detector 302 can be used to detect: the concentration of combustible gas in the battery compartment 107, the presence of smoke in the battery compartment 107, the temperature in the battery compartment 107, and the humidity in the battery compartment 107, etc. The detector 302 may specifically include: a carbon monoxide gas detector, a photoelectric smoke gas detector, etc. The detector 302 can report the collected temperature values ​​and gas content to the fire control panel to realize fire early warning.

[0063] In these embodiments, the detector 302 is disposed on the top wall 115 and in the battery compartment 107, and can detect the presence of combustible gas. Alternatively, the detector 302 can detect whether the concentration of combustible gas in the battery compartment 107 has reached a certain threshold. When combustible gas is present in the battery compartment 107, or when the concentration of combustible gas in the battery compartment 107 has reached a certain threshold, the battery compartment 107 is determined to be in a first state. At this time, the exhaust fan 301 is activated, and the first damper 303 and the second damper 305 are opened to promote gas flow within the battery compartment 107. Specifically, the first damper 303 works in conjunction with the exhaust fan 301 to expel combustible gas from the battery compartment 107, while external gas enters the battery compartment 107 through the second damper 305, thereby reducing the concentration of combustible gas within the battery compartment 107.

[0064] Please combine Figure 6 In some embodiments, detector 302 can be used to detect the concentration of combustible gas; the fire protection system 300 also includes an alarm 307, which is disposed in the battery compartment 107 and installed on the top wall 115. The alarm 307 is electrically connected to detector 302 and is used to sound an alarm when the concentration of combustible gas reaches a threshold. Alarm 307 may specifically include an audible and visual alarm. In some embodiments, the audible and visual alarm responds when combustible gas is present in the battery compartment 107, or when the concentration of combustible gas in the battery compartment 107 has reached a certain threshold.

[0065] Please combine Figure 10 In some embodiments, the fire protection system 300 further includes a sprinkler mechanism 310. At least a portion of the sprinkler mechanism 310 is disposed in the battery compartment 107 and connected to the top wall 115 for spraying fire extinguishing agent onto the battery compartment 107. When the battery compartment 107 is in the second state, the first damper 303 and the second damper 305 are closed, the exhaust fan 301 stops working, and the sprinkler mechanism 310 can spray fire extinguishing agent onto the battery compartment 107. When the battery compartment 107 is in the second state, it means that there may be a fire in the battery compartment 107, causing the first damper 303 and the second damper 305 to close. At this time, the sprinkler mechanism 310 can spray fire extinguishing agent onto the battery compartment 107.

[0066] In some embodiments, when flammable gas is present in the battery compartment 107, or when the concentration of flammable gas in the battery compartment 107 has reached a certain threshold, an audible and visual alarm is triggered, and the sprinkler mechanism 310 sprays extinguishing agent into the battery compartment 107. The extinguishing agent may include heptafluoropropane, stored in a storage cylinder assembly, which may be fixed within the electrical compartment 109. The storage cylinder assembly may be connected to a gas hose extending from the electrical compartment 109 into the battery compartment 107, facilitating the spraying of the extinguishing agent into the battery compartment 107.

[0067] In some embodiments, the fire alarm control panel may be equipped with a panel, which includes an emergency stop button, audible and visual alarm lights, and fault lights. In some embodiments, when all the doors of the battery compartment 107 are closed, if the detector 302 detects abnormal smoke and temperature, the sprinkler system 310 will spray fire extinguishing agent onto the battery compartment 107.

[0068] The first air damper 303 and the second air damper 305 can be configured to open and close simultaneously. Thus, when either the first air damper 303 or the second air damper 305 is closed, both air dampers 303 and 305 will be simultaneously shut off. When the battery compartment 107 is in the second state, the following operations may be performed to cause the first air damper 303 and the second air damper 305 to close simultaneously: the operator can manually control the first air damper 303 to close; the operator can manually control the second air damper 305 to close; the operator can manually control both the first and second air dampers 303 to close; the first air damper 303 is passively de-energized; the second air damper 305 is passively de-energized; the first and second air dampers 303 are passively de-energized; the fusible link of the first air damper 303 melts; the fusible link of the second air damper 305 melts; the fusible links of both the first and second air dampers 303 melt.

[0069] In some embodiments, the battery compartment 107 can switch from a normal operating state to a second state: When the battery compartment is in the normal operating state, the exhaust fan 301 stops working, and both the first air damper 303 and the second air damper 305 remain open to maintain natural ventilation of the battery compartment 107, that is, the outside air and the gas inside the battery compartment can be naturally exchanged; when the battery compartment 107 is in the second state, the exhaust fan 301 stops working, both the first air damper 303 and the second air damper 305 remain closed, and the spray mechanism 310 sprays fire extinguishing agent onto the battery compartment 107. In some embodiments, the battery compartment can switch from a first state to a second state: When the battery compartment 107 is in the first state, the exhaust fan operates, and the first air damper and the second air damper open. The first air damper cooperates with the exhaust fan to exhaust at least part of the gas inside the battery compartment, and the outside air enters the battery compartment 107 through the second air damper. When the battery compartment 107 is in the second state, the exhaust fan 301 stops working, the first air damper 303 and the second air damper 305 remain closed, and the sprinkler mechanism 310 sprays fire extinguishing agent onto the battery compartment 107.

[0070] Please combine Figure 7 In some embodiments, the energy storage system also includes a plurality of explosion-proof lighting elements 501 installed on the top wall 115, with at least some of the explosion-proof lighting elements 501 disposed in the battery compartment 107. In some embodiments, the explosion-proof lighting elements 501 may specifically be explosion-proof lamps, and the opening and closing of the explosion-proof lamps are controlled by a lighting control switch. The lighting control switch may be located near the door of the enclosure 100.

The battery module 600 is installed in a battery compartment 107, and the electrical module 700 is installed in an electrical compartment 109. The battery compartment 107 is isolated from the electrical compartment 109. The battery module 600 includes a plurality of battery pack clusters 610, and a battery pack cluster 610 includes a plurality of battery packs 611 connected in series.

[0076] Electrical assembly 700 includes a high-voltage box assembly 710 and a high-voltage cabinet 750. The high-voltage box assembly 710 includes multiple high-voltage box groups 711. Each high-voltage box group 711 includes multiple high-voltage boxes 713. Each high-voltage box 713 is electrically connected to a battery pack cluster 610. The high-voltage cabinet 750 includes multiple management sections. One management section is used to combine and manage the multiple high-voltage boxes 713 of the high-voltage box group 711.

[0077] In these embodiments, the battery assembly 600 includes multiple battery pack clusters 610, and a high-voltage box 713 is electrically connected to a battery pack cluster 610, so that a failure of a battery pack cluster 610 will not affect the normal operation of other battery pack clusters 610. The high-voltage cabinet 750 includes multiple management sections, one of which is used for current collection and management of the multiple high-voltage boxes 713 in a high-voltage box group 711. Thus, a failure of one high-voltage box 713 in a high-voltage box group 711 will not affect the normal operation of the other high-voltage boxes 713 in the same high-voltage box group 711. Furthermore, a failure of one management section of a high-voltage cabinet 750 will not affect the normal operation of the other management sections of the high-voltage cabinet 750.

[0078] In some embodiments, electrical component 700 can be configured as explosion-proof to meet the electromagnetic compatibility requirements of ships. Electrical component 700 meets the testing items of GD22-2015, and the materials of electrical component 700 meet RoHS environmental protection requirements.

[0079] In some embodiments, electrical component 700 includes high-voltage electrical components and low-voltage electrical components. The high-voltage electrical components may include a high-voltage box 713 and a high-voltage cabinet 750. The high-voltage box 713 is primarily used for energy conversion and transmission. The high-voltage cabinet 750 is primarily used for combining and managing multiple high-voltage boxes 713. The low-voltage electrical components may include a battery management system (BMS) and an auxiliary power supply. The BMS is used for the detection, protection, and management of the battery components.

[0080] In some embodiments, the main body material of the high-voltage switchgear 750 can be SPCC, the corrosion resistance level of the high-voltage switchgear 750 can be greater than or equal to C5, the leakage current of the 3500VAC withstand voltage test is ≤10mA, the insulation level at 1000VDC is ≥550MΩ, and the charging connection device of the high-voltage switchgear is equipped with mechanical interlock to prevent the charging cable from falling off during the live plugging and unplugging charging process.

[0081] In some embodiments, the high-voltage box 713 can transmit signals with the high-voltage cabinet 750. The high-voltage box 713 can receive online / offline commands from the high-voltage cabinet 750, control the balance of relay switch and cell voltage, and has a fault feedback function. The high-voltage box 713 may also have an isolating switch to realize the isolation of the manual electrical system, facilitating installation and maintenance.

[0082] In some embodiments, CAN communication can be used to transmit information with the high-voltage box 713, and the BMS slave controller can transmit the information in the battery pack to the BMS master controller.

[0083] In some embodiments, the high-voltage box 713 can convert input electrical energy into high-voltage electricity suitable for storage or further transmission. For example, in some examples, charging the battery pack requires a specific high-voltage input, and the high-voltage box can boost a lower voltage to a suitable high-voltage value for efficient charging of the battery pack. In some examples, when transmitting electrical energy externally, such as to supply power to external loads (e.g., large industrial equipment, power grids), the high-voltage box can convert the output voltage of the battery pack into high-voltage electricity suitable for long-distance transmission.

[0084] In some embodiments, the high-voltage switchgear 750 can combine the currents transmitted from multiple high-voltage boxes 713 to obtain a larger total current for subsequent power processing, such as transmission to an inverter or energy storage system. Simultaneously, it can also distribute power to various branches according to different load demands or the requirements of energy storage devices. For example, a portion of the power can be distributed to battery modules for storage, while another portion can be distributed to an inverter to convert it into AC power for use by external loads.

[0085] In some embodiments, the BMS (Battery Management System) can monitor the battery pack voltage in real time. In an energy storage system, the battery pack comprises multiple battery cells, and the voltage of different cells may vary due to differences in battery characteristics, charge / discharge states, and other factors. The BMS can measure the voltage of each battery cell using voltage detectors. By monitoring the voltage and charging current of the battery cells, the BMS will immediately disconnect the charging circuit or reduce the charging current once it detects that the voltage of a battery cell has reached the overcharge protection threshold, preventing damage to the battery cell due to overcharging, such as bulging, burning, or even explosion. The BMS can also manage various information about the battery pack, such as battery model, capacity, charge / discharge cycle count, and historical fault records.

[0086] In some embodiments, the BMS (Battery Management System) may have visual and audible alarm functions, and may have power failure alarm detection functions.

[0087] Please combine Figure 12 In some embodiments, the battery assembly 600 may include eight battery pack clusters 610, and a battery pack cluster 610 includes a plurality of battery packs 611 connected in series.

[0088] Please combine 12 and Figure 15 The electrical component 700 includes a high-voltage box assembly 710 and a high-voltage cabinet 750. The high-voltage box assembly 710 includes two high-voltage box groups 711. Each high-voltage box group 711 includes four high-voltage boxes 713. Each high-voltage box 713 is electrically connected to a battery pack cluster 610. The high-voltage cabinet 750 includes two management sections. One management section is used to combine and manage the multiple battery pack clusters 610 corresponding to the multiple high-voltage boxes 713 of the high-voltage box group 711.

[0089] In some embodiments, the energy storage system further includes a battery rack assembly 800, which is primarily used for storing and managing the battery components. The battery rack 800 may be made of steel.

[0090] Please combine Figure 12 The battery rack assembly 800 includes corner posts 810, crossbeams 820, and shelves. The crossbeams 820 extend horizontally, the corner posts 810 are connected to the crossbeams 820 and perpendicular to the crossbeams 820, and the shelves are mounted on the crossbeams 820 to support the battery assembly 600.

[0091] The corner posts 810 are the main vertical support members of the battery rack assembly 800, and are typically located at each corner. The corner posts 810 provide the main vertical support for the battery rack assembly 800.

[0092] In some embodiments, the corner post 810 has a cavity for filling with insulation. In some embodiments, the insulation may include rock wool board. In some embodiments, the insulation may include polyurethane foam. In some embodiments, the insulation may include polystyrene foam. In some embodiments, the insulation may include glass wool.

[0093] In some embodiments, the corner posts 810 of the battery rack assembly 800 can be configured as Q355 square steel. The hollow part of the square steel, i.e. the cavity provided in the corner post 810, can be filled with rock wool board, thereby increasing the heat insulation and deformation resistance of the battery rack assembly 800, and giving the battery rack assembly 800 better flame retardancy and waterproofness.

[0094] The crossbeam 820 is the main horizontal support component of the battery rack assembly 800, used to connect the corner posts 810 located on both sides of the crossbeam 820. The crossbeam 820 not only provides horizontal stability but also serves as the main platform for placing the battery assembly. The crossbeam 820 is typically fixed to the corner posts 810 by bolts or welding.

[0095] Shelves are the parts that directly support the battery packs. Shelves can be fixed or height-adjustable to accommodate different sizes or numbers of battery packs. Shelves are typically made of sheet metal and need to have sufficient load-bearing capacity.

[0096] The battery assembly 600 includes multiple battery pack clusters 610, and each battery pack cluster 610 includes multiple battery packs 611 connected in series. The battery assembly 600 is disposed in the battery compartment 107, and the high-voltage box 713 is disposed in the electrical compartment 109.

[0097] The battery rack assembly 800 may include multiple layers of shelves arranged vertically. Multiple battery packs may be arranged on a single shelf, and the multiple battery packs on a single shelf are connected in series to form a battery pack cluster 610. In some embodiments, eight battery pack clusters 610 may be provided.

[0098] In some embodiments, the battery rack assembly 800 may be equipped with cable ties, which can reduce tangling problems caused by messy wiring of communication cables, power cables, etc., and facilitate later maintenance. The cable ties and the battery rack assembly 800 can be configured to be detachably connected and reused.

[0099] In some embodiments, the energy storage system may also have dynamic environmental monitoring capabilities for enhanced safety. The energy storage system may include three sliding doors, near which emergency lighting and other equipment can be installed. The energy storage system may also include explosion-proof video surveillance, which can be connected to a UPS power supply. A UPS (Uninterruptible Power Supply) is a device that provides a continuous, stable, and uninterrupted power supply to load equipment in the event of a power outage or abnormality.

[0100] In some embodiments, the electrical component 700 further includes an auxiliary power supply 730, which is disposed in the electrical compartment 109 and electrically connected to the battery assembly to provide backup power to the battery assembly.

[0101] In some embodiments, the auxiliary power supply may be used to provide dual 220VAC power to the battery assembly and other components within the energy storage system.

[0102] In some embodiments, the auxiliary power supply is located in the electrical compartment and is electrically connected to the fire protection system. The auxiliary power supply provides dual 220VAC power to the fire protection system.

[0103] In some embodiments, when the battery compartment 107 is in the first state, the battery assembly can be turned off, and only the auxiliary power supply can power the exhaust fan 301, the first air damper 303 and the second air damper 305. When the concentration of combustible gas decreases to a safe range, the exhaust fan 301, the first air damper 303 and the second air damper 305 are closed, thereby preventing air from entering the compartment. At the same time, the alarm is triggered to facilitate subsequent personnel handling.

[0104] The high-voltage box 713 can be installed close to the partition 103, and the high-voltage cabinet 750 is located between the high-voltage box assembly 710 and the auxiliary power supply 730. The partition 103 can be configured as a steel plate with a thickness of 5mm.

[0105] In these embodiments, the energy storage system includes a battery module 600 and an auxiliary power supply 730. The battery module 600 is located in the battery compartment 107 and serves as the main power source, while the auxiliary power supply 730 is located in the electrical compartment 109. In some embodiments, the auxiliary power supply 730 may include four batteries, capable of taking over power to the fire protection system 300 and other systems after a complete failure of the battery module 600, thus maintaining the normal operation of all components within the energy storage system.

[0106] Please combine Figure 5 , Figure 13 as well as Figure 14The energy storage system can use liquid cooling technology to dissipate heat from the battery pack 600. In some embodiments, the energy storage system further includes a liquid cooling system, which may include a liquid cooling host 201, a main pipeline 203, and a distribution pipeline 205. The liquid coolant in the liquid cooling host 201 flows out to the main pipeline 203, and the liquid coolant flowing into the main pipeline 203 is distributed to the battery pack 611 through the distribution pipeline 205. After cooling the battery pack 611, the liquid coolant converges from the distribution pipeline 205 to the main pipeline 203 and flows back to the liquid cooling host 201.

[0107] In some embodiments, the liquid cooling unit 201 may have a liquid refrigerant outlet and a liquid refrigerant inlet. The main pipeline 203 may include an inlet pipe and an outlet pipe. The inlet pipe is connected to the liquid refrigerant outlet, and the outlet pipe is connected to the liquid refrigerant inlet. One end of the distribution pipeline 205 is connected to the inlet pipe, and the other end of the distribution pipeline is connected to the outlet pipe. The refrigerant in the main pipeline 203 is distributed to the battery pack via the distribution pipeline 205. In these embodiments, the liquid cooling unit 201 distributes the liquid refrigerant to the battery pack 611 to dissipate heat from the battery pack 611 and maintain the normal operation of the battery pack 611.

[0108] Please combine Figure 2 In some embodiments, the second sidewall may be provided with an observation window 901, which facilitates observation of the status of the liquid cooling unit through the observation window.

[0109] In some embodiments, the main pipeline 203 may be wrapped with insulating cotton to prevent condensation.

[0110] Please combine Figure 3 In some embodiments, a waterproof drain 904 can be provided at the bottom of the enclosure to facilitate the drainage of condensate. In some embodiments, the waterproof drain 904 can be made of brass with a nickel-plated surface. Magnetic sealing can also be used to effectively prevent external gases from diffusing into the enclosure.

[0111] In some embodiments, the main pipeline 203 can be arranged on the top wall 115 of the battery compartment 107 and located on the side of the battery compartment 107. Specifically, the main pipeline 203 can be fixed to the top wall 115 and the side of the battery compartment 107 by a metal clamp assembly. The liquid cooling pipes are arranged in parallel around the battery rack assembly 800. The main body of the liquid cooling pipes is made of 316 stainless steel, and the wrapping material is a fiber braided layer. The distribution pipelines are arranged around the battery rack assembly 800. Multiple distribution pipelines 205 can be connected in parallel. The main body of the distribution pipelines 205 can be configured to be made of 316 stainless steel, and the wrapping material of the distribution pipelines 205 can be configured to be a fiber braided layer.

[0112] In some embodiments, a mini ball valve may be provided between the inlet pipe of the distribution line 205 and the inlet pipe of the main line 203 to control the flow of fluid.

[0113] In some embodiments, the other end of the distribution line 205, which is connected to the outlet pipe of the main line 203, may be equipped with a mini ball valve to control the flow of fluid.

[0114] In some embodiments, there may be multiple distribution lines 205, and a battery pack cluster 610 may be cooled by two distribution lines.

[0115] In these embodiments, liquid cooling technology is used to reduce the temperature of the liquid cooling plate of the battery pack. Ethylene glycol can be used as the liquid coolant, which can significantly improve heat dissipation efficiency, reduce reliance on fans and air conditioning systems, and reduce overall energy consumption.

[0116] In some embodiments, the liquid cooling system may further include a main motor and a backup motor, wherein the backup motor can take over the operation of the main motor if the main motor fails.

[0117] In some embodiments, the liquid cooling capacity of the liquid cooling system reaches 15KW.

[0118] In some embodiments, the main pipeline can be made of stainless steel and PA12 (polyamide 12), or stainless steel and PP (polypropylene), which has good corrosion resistance and aging resistance.

[0119] The distribution pipes can be made of stainless steel and PA12 (polyamide 12), or stainless steel and PP (polypropylene), thus providing excellent corrosion resistance and aging resistance.

[0120] In some embodiments, the energy storage system also includes a dehumidifier. The fire suppression system 300, electrical components, and battery modules 600 of the energy storage system are sensitive to ambient humidity. If the ambient humidity is too high, water vapor may condense into water droplets on the surfaces of the fire suppression system 300, electrical components, and battery modules 600. This can lead to short circuits; for example, water droplets may create conductive paths between different lines on a circuit board, thereby damaging the equipment. The dehumidifier reduces the humidity inside the enclosure 100, reducing the possibility of water vapor condensation, thus effectively protecting the normal operation of the fire suppression system, electrical components, and battery modules 600, and extending the lifespan of the energy storage system. Furthermore, high humidity environments also easily breed mold and other microorganisms. The dehumidifier reduces humidity, inhibiting the growth of mold and other microorganisms, thereby ensuring the safety of the entire energy storage system.

[0121] In some embodiments, the dehumidifier can meet the 85% RH requirement and has a dehumidification capacity of 400 ml / day.

[0122] In some embodiments, the auxiliary materials of the battery assembly 600 may be configured as flame-retardant materials. For example, if the outer casing material or the insulating material of the battery assembly 600 uses a flame-retardant material, then when a thermal runaway occurs in a battery pack 611, the flame-retardant material can delay the spread of flames and prevent the thermal runaway from spreading within the battery assembly. This can prevent the failure of a single battery pack from spreading to the entire battery assembly, reducing the risk of fire and explosion. Specific flame-retardant materials may include polycarbonate (PC), polyamide (PA), etc.

[0123] In some embodiments, electrical equipment that continues to operate under thermal runaway conditions may be configured as explosion-proof electrical equipment.

[0124] Please combine Figure 16 In some embodiments, the second sidewall 113 may be provided with an alarm host 906, which has a display screen for operators to view alarm information.

[0125] Secondly, embodiments of this application also provide an electric vessel that includes the aforementioned energy storage system. The energy storage system is capable of providing power to the vessel.

[0126] In these embodiments, the battery assembly 600 includes multiple battery pack clusters 610, and a high-voltage box 713 is electrically connected to a battery pack cluster 610, so that a failure of a battery pack cluster 610 will not affect the normal operation of other battery pack clusters 610.

[0127] The high-voltage switchgear 750 includes multiple management sections, one of which is used to combine and manage the multiple high-voltage boxes 713 of a high-voltage box group 711. In this way, if one high-voltage box 713 of the high-voltage box group 711 fails, it will not affect the normal operation of the other high-voltage boxes 713 in the high-voltage box group 711.

[0128] Furthermore, a malfunction in one management section of a high-voltage switchgear 750 will not affect the normal operation of other management sections of the same high-voltage switchgear 750.

[0129] The energy storage system includes battery modules and an auxiliary power supply 730. The battery modules are located in the battery compartment and serve as the main power source, while the auxiliary power supply 730 is located in the electrical compartment. In some embodiments, the auxiliary power supply 730 may include four batteries, capable of taking over power to the fire suppression system and other systems in the event of a complete failure of the battery modules. This ensures the normal operation of all components of the energy storage system, preventing a single failure from causing a power outage for the electric vessel.

[0130] Thirdly, embodiments of this application also provide a fire extinguishing method, which is applied to the aforementioned energy storage system or the aforementioned electric vessel, and the fire extinguishing method includes:

[0131] The detector 302 based on the energy storage system acquires parameter information of the electrical compartment 109;

[0132] The exhaust fan is controlled to operate according to the parameter information, and the first damper 303 and the second damper 305 are controlled to open.

[0133] In some embodiments, the fire extinguishing method includes: acquiring parameter information of the electrical compartment 109 based on the detector 302 of the energy storage system; controlling the exhaust fan to operate according to the parameter information; and controlling the opening of the first damper 303 and the second damper 305, including:

[0134] The detector 302 of the energy storage system acquires the first environmental information of the environment where the electrical compartment 109 is located, including the concentration information of combustible gas.

[0135] When the first environmental information exceeds the first threshold, the exhaust fan is controlled to work, and the first damper 303 and the second damper 305 are controlled to open.

[0136] In these embodiments, detector 302 can be used to detect: the concentration of combustible gas in battery compartment 107, the presence of smoke in battery compartment 107, the temperature in battery compartment 107, and the humidity in battery compartment 107. Detector 302 may specifically include: a carbon monoxide gas detector, a photoelectric smoke gas detector, etc. Detector 302 can report the collected temperature values ​​and gas content to the fire alarm control panel to achieve fire early warning. Combustible gases may include: hydrogen, methane, carbon monoxide, ethylene, acetylene, etc.

[0137] In some embodiments, when the first environmental information exceeds a first threshold, it means that there is a certain concentration of flammable gas in the battery compartment 107, posing a safety hazard. At this time, the exhaust fan is activated, and the first damper 303 and the second damper 305 are opened. The exhaust fan 301 and the first damper 303 work together to exhaust the gas in the battery compartment 107, accelerate the gas exchange between the battery compartment 107 and the outside of the energy storage system, quickly reduce the concentration of flammable gas in the battery compartment 107, and allow the battery compartment 107 to return to normal operation, preventing the accumulation of thermal runaway gas that could lead to an explosion in the battery compartment 107.

[0138] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model.

Therefore, the content of this specification should not be construed as a limitation of this utility model.
