Technical Field

[0002] This application relates to the field of battery technology, and more specifically, to an energy storage system. Background Technology

[0003] With the rapid development of technology, electricity has become an indispensable energy source in people's production and daily life. To improve the smoothness of electricity supply and ensure the normal operation of production and daily life, energy storage systems are needed. Energy storage systems can achieve the cyclical storage and release of electrical energy. By charging or discharging the battery devices in the energy storage system, electrical energy can be stored in the system or supplied to electrical devices. Energy storage systems are widely used in industrial power supply, household power supply, temporary power supply, mobile power supply, wind power generation, solar power generation, and energy storage power stations.

[0004] In the development of energy storage systems, in addition to improving the performance of energy storage systems, how to improve the volumetric energy density of energy storage systems is also an issue that cannot be ignored. Summary of the Invention

[0005] This application provides an energy storage system, and the technical solution provided by this application can improve the volumetric energy density of the energy storage system.

[0006] This application is achieved through the following technical solution:

[0007] In one aspect, some embodiments of this application provide an energy storage system, which includes multiple battery devices, a first compartment, a second compartment, a first fire-fighting mechanism, a second fire-fighting mechanism, and a fire control module. Battery devices are housed in both the first and second compartments. The first fire-fighting mechanism is located in the first compartment. The second fire-fighting mechanism is located in the second compartment. The fire control module is located in either the second or first compartment, and is communicatively connected to the first and second fire-fighting mechanisms to control their operation, respectively.

[0008] In the above scheme, the fire control module can control the first fire-fighting mechanism and the second fire-fighting mechanism respectively, and the fire control module is set in one of the first and second compartments. On the one hand, it can improve the integration of fire control of the energy storage system, which is conducive to cost control and easy maintenance of the fire control module; on the other hand, it can reduce the space occupied by the fire control module in the internal space of the energy storage system, so that the energy storage system can arrange more battery devices, which in turn is conducive to improving the volumetric energy density of the energy storage system.

[0009] According to some embodiments of this application, the first compartment and the second compartment are stacked along the height direction, with the first compartment located above the second compartment, and the fire control module is disposed in the second compartment.

[0010] In the above scheme, by setting the fire control module in the lower second compartment, the installation and maintenance difficulty of the fire control module can be reduced, effectively improving the convenience of deployment and maintenance of the energy storage system. On the other hand, since the fire control module does not occupy the internal space of the first compartment, more battery devices can be arranged in the first compartment, which is conducive to improving the volumetric energy density of the energy storage system.

[0011] According to some embodiments of this application, a first fire-fighting mechanism is used to release aerosols, and a second fire-fighting mechanism is used to release aerosols.

[0012] In the above scheme, the fire-fighting medium released by the first and second fire-fighting agencies is set as an aerosol. On the one hand, it can quickly extinguish the fire source and reduce the risk of further combustion of the energy storage system. On the other hand, it can reduce the risk of short circuits between battery devices caused by the fire-fighting medium, thereby improving the reliability of the energy storage system.

[0013] According to some embodiments of this application, the energy storage system further includes a first detector and a second detector. The first detector is disposed within a first compartment and is used to detect a first fire signal within the first compartment. The second detector is disposed within a second compartment and is used to detect a second fire signal within the second compartment. A fire control module is communicatively connected to the first and second detectors and is configured to control a first fire-fighting mechanism to operate in response to the first fire signal and to control a second fire-fighting mechanism to operate in response to the second fire signal.

[0014] In the above scheme, the fire control module is communicatively connected to the first detector and the second detector, enabling the fire control module to respond to the first fire signal or the second fire signal to control the first fire-fighting mechanism and the second fire-fighting mechanism to work respectively, thereby accurately extinguishing the fire at the ignition point, achieving rapid extinguishing of the flames, and thus improving the reliability of the energy storage system.

[0015] According to some embodiments of this application, the energy storage system further includes a first connector and a second connector. The first connector is connected to a first fire-fighting mechanism and a first detector via a first wiring harness. The second connector is connected to a fire control module via a second wiring harness, and the first and second connectors are plugged into each other.

[0016] In the above scheme, by setting up a first connector and a second connector that plug into each other, the communication connection between the fire control module and the first fire-fighting mechanism and the first detector can be quickly realized, reducing the installation and commissioning procedures for users on site, reducing the wiring difficulty between the fire communication lines between the first and second compartments, thereby improving the efficiency of energy storage system deployment.

[0017] According to some embodiments of this application, the second connector is connected to the second detector via a second wiring harness.

[0018] In the above scheme, the second detector is connected to the second connector through the second wiring harness, which enables the first detector, the second detector and the fire control module to form a loop, simplifying the layout of communication lines between the first detector and the fire control module, and between the second detector and the fire control module. This reduces the space occupied by the communication lines in the energy storage system, allowing the energy storage system to accommodate more battery devices, thereby improving the volumetric energy density of the energy storage system.

[0019] According to some embodiments of this application, the first wiring harness includes a first wire, a second wire, and a third wire. The first wire is connected to a first fire protection mechanism, and the second and third wires are respectively connected to a first detector. The second wiring harness includes a fourth wire, a fifth wire, and a sixth wire. The fourth wire is connected to a fire control module, the fifth wire is connected to the fire control module, and the sixth wire is connected to a second detector. The fire control module and the second detector are communicatively connected. When the first connector and the second connector are plugged in, the first wire and the fourth wire are interconnected; the second wire and the fifth wire are interconnected; and the third wire and the sixth wire are connected, so that the first detector, the fire control module, and the second detector form a circuit.

[0020] In the above scheme, the first connector integrates the first wire, the second wire, and the third wire, and the second connector integrates the fourth wire, the fifth wire, and the sixth wire. Through the quick plugging and unplugging of the first connector and the second connector, the communication connection between the fire control module and the fire-fighting components in the first compartment can be quickly realized, reducing the installation and commissioning procedures for users on site, reducing the wiring difficulty between the fire communication lines between the first compartment and the second compartment, thereby improving the efficiency of energy storage system deployment.

[0021] According to some embodiments of this application, the energy storage system further includes a first alarm and a second alarm. The first alarm is disposed within a first compartment and is used to issue an alarm signal in response to a first fire signal. The second alarm is disposed within a second compartment and is used to issue an alarm signal in response to a second fire signal. A first connector is connected to the first alarm via a first wiring harness, and a second connector is connected to the second alarm via a second wiring harness. The second alarm is communicatively connected to a fire control module.

[0022] In the above scheme, by setting up a first alarm and a second alarm, personnel can be alerted during firefighting, shortening their reaction time and improving firefighting efficiency. Simultaneously, the first alarm, connected to the first connector via a first wiring harness, can quickly establish communication with the fire control module, reducing on-site installation and commissioning procedures and improving the deployment efficiency of the energy storage system. Furthermore, the second alarm, connected to the second connector via a second wiring harness, forms a loop between the first alarm, the fire control module, and the second alarm, simplifying the communication line layout between the first alarm and the fire control module, and between the second alarm and the fire control module. This reduces the space occupied by communication lines within the energy storage system, allowing for the placement of more battery devices and ultimately improving the volumetric energy density of the energy storage system.

[0023] According to some embodiments of this application, the first detector includes a first smoke detector and a first heat detector, and the second detector includes a second smoke detector and a second heat detector; the first wiring harness includes signal lines for the first fire-fighting mechanism, the first smoke detector, the first heat detector, and the first alarm; and / or, the second wiring harness includes signal lines for the second smoke detector, the second heat detector, and the second alarm.

[0024] In the above solution, smoke detectors and heat detectors can combine smoke characteristic information and temperature information to obtain accurate fire signals, thereby comprehensively judging the fire situation and accurately controlling the release of fire-fighting media by the fire-fighting mechanism. This reduces the risk of fire-fighting media affecting the reliability of the energy storage system due to misjudgment, thus improving the reliability of the energy storage system. At the same time, the signal lines of the first fire-fighting mechanism, the first smoke detector, the first heat detector, and the first alarm are integrated into the first connector through the first wiring harness, and the signal lines of the second smoke detector, the second heat detector, and the second alarm are integrated into the second connector through the second wiring harness. With the quick plugging and unplugging of the first and second connectors, the communication connection between the fire control module and the fire-fighting components in the first compartment can be quickly realized, reducing the installation and commissioning procedures for users on site and reducing the wiring difficulty between the fire communication lines of the first and second compartments, thereby improving the deployment efficiency of the energy storage system.

[0025] According to some embodiments of this application, a first chamber is provided with a first vent, and a first fan is provided in the first vent for discharging gas from the first chamber. The energy storage system also includes a third detector disposed within the first chamber for detecting gas signals within the first chamber. The first fan is configured to start in response to the gas signal, and a first connector is connected to the third detector via a first wiring harness.

[0026] In the above scheme, the concentration of combustible gas inside the first compartment is detected by a third detector. Combined with the operation of the first fan, this effectively removes the combustible gas from the first compartment, reducing the risk of explosion in the energy storage system and improving its reliability. Simultaneously, the third detector and the first fan are connected to the first connector via a first wiring harness, enabling rapid communication with the fire control module. This reduces on-site installation and commissioning procedures for users, thereby improving the efficiency of energy storage system deployment.

[0027] According to some embodiments of this application, the first wiring harness includes the signal line of the third detector.

[0028] The above solution integrates the signal line of the third detector into the first connector through the first wiring harness. With the quick plugging of the first connector and the second connector, the communication connection between the fire control module and the third detector can be quickly realized, reducing the installation and commissioning procedures on site for users and reducing the wiring difficulty between the fire communication lines between the first and second compartments, thereby improving the efficiency of energy storage system deployment.

[0029] According to some embodiments of this application, one of the first connector and the second connector is provided with a foolproof protrusion, and the other is provided with a foolproof groove, wherein the foolproof protrusion is used to mate with the foolproof groove.

[0030] In the above solution, by setting mutually cooperating anti-mistake protrusions and anti-mistake grooves between the first connector and the second connector, the risk of incorrect connection of the first connector and the second connector can be reduced, thereby improving the efficiency of energy storage system deployment.

[0031] According to some embodiments of this application, both the first connector and the second connector are disposed in the first compartment.

[0032] In the above solution, by placing both the first connector and the second connector in the first compartment, the space occupied by the first connector and the second connector in the second compartment can be reduced, as well as the risk of interference between the first connector and the second connector and other structural components in the second compartment can be reduced, making it easier to arrange the battery device and other electrical components in the second compartment.

[0033] According to some embodiments of this application, the first compartment and the second compartment are stacked along the height direction, the first compartment is located above the second compartment, the bottom wall of the first compartment is provided with a first through hole, the top wall of the second compartment is provided with a second through hole, and a portion of the second wire harness passes through the second through hole and the first through hole.

[0034] In the above scheme, by setting a first through hole on the bottom wall of the first compartment and a second through hole on the top wall of the second compartment, the wiring layout of the second harness can be facilitated, which is conducive to improving the deployment efficiency of the energy storage system.

[0035] According to some embodiments of this application, a first compartment and a second compartment are stacked along the height direction, and at least one of the dimensions of the first compartment along the height direction and the dimensions of the second compartment along the height direction is smaller than the dimensions of a standard container along the height direction.

[0036] In the above scheme, by setting the height of one of the first and second compartments to be less than that of a standard container, one of the first and second compartments can be transported independently, meeting the transportation requirements of the energy storage system. On the other hand, because the height of one of the first and second compartments is smaller, the diffusion time of the fire-fighting medium released by the fire-fighting agency can be shortened, thereby improving the efficiency of fire extinguishing and thus improving the reliability of the energy storage system.

[0037] According to some embodiments of this application, the energy storage system further includes a control module for electrically controlling a plurality of battery devices within the first and second compartments, the control module being housed in one of the first and second compartments.

[0038] In the above scheme, the control module electrically controls all battery devices in the energy storage system, integrating the first and second compartments into a single energy storage system to facilitate the control of energy storage and discharge. Simultaneously, the battery devices in both compartments are controlled by the same control module, reducing the space occupied by the control module within the energy storage system and contributing to an increase in the volumetric energy density of the energy storage system.

[0039] According to some embodiments of this application, the sum of the dimensions of the first compartment along the height direction and the dimensions of the second compartment along the height direction is greater than or equal to the dimensions of a standard container along the height direction.

[0040] In the above scheme, by setting the sum of the height dimensions of the two compartments to be greater than or equal to the height dimension of a standard container, the energy storage system can have a larger dimension in the height direction. This is beneficial to increasing the space of the first and second compartments in the height direction, allowing more battery devices to be installed in the first and second compartments in the height direction, thereby increasing the volumetric energy density of the energy storage system.

[0041] According to some embodiments of this application, the dimensions of the first and second compartments along their length are consistent with the dimensions along the length of a standard container, and the dimensions of the first and second compartments along their width are consistent with the dimensions along the width of a standard container.

[0042] In the above scheme, the dimensions of each compartment are the same as those of a standard container in both length and width. This makes the floor area of ​​the first and second compartments the same as that of a standard container, which can reduce the transportation difficulty and cost of the first and second compartments.

[0043] According to some embodiments of this application, the standard container is a 20-foot standard container.

[0044] According to some embodiments of this application, the total energy of the energy storage system is 9MWh-11MWh.

[0045] In the above scheme, the energy storage system has high energy, which can improve the performance of the energy storage system.

[0046] According to some embodiments of this application, the total weight of the first compartment and the components disposed in the first compartment is less than or equal to 36 tons; and / or, the total weight of the second compartment and the components disposed in the second compartment is less than or equal to 36 tons.

[0047] In the above scheme, the weight of both the first and second warehouses is no more than 36 tons, which facilitates the transportation of the first and second warehouses and reduces transportation costs.

The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited thereto.

[0066] The battery mentioned in the embodiments of this application may be a single physical module comprising one or more battery cells to provide higher voltage and capacity. When there are multiple battery cells, the multiple battery cells are connected in series, parallel, or mixed via a busbar.

[0067] In some embodiments, the battery can be a battery module; when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0069] In some embodiments, the energy storage system includes energy storage containers, energy storage cabinets, etc.

[0070] A single battery cell typically includes an electrode assembly. The electrode assembly includes a positive electrode, a negative electrode, and a separator.

Wind power systems collect wind energy from wind turbines, convert it into electricity, and then store it in an energy storage system. Solar power systems convert solar energy into electricity, store it in an energy storage system, and supply it to users as needed. Mobile power systems can power equipment in areas inaccessible by the mains grid, such as remote mountainous areas and isolated wilderness areas. Temporary power supply systems can provide power to users when there is insufficient electricity.

[0079] In the development of energy storage systems, to improve their reliability, fire suppression systems are often equipped with fire-fighting mechanisms to address fire hazards. For example, these systems may include fire suppression mechanisms and fire control modules that communicate with them to control the release of fire-fighting agents. When a fire occurs in the energy storage system or a fire signal is detected, the fire control module activates the fire suppression mechanisms to release fire-fighting agents, thus extinguishing the fire, reducing structural damage to the system, and mitigating the risk of fire spread.

[0080] In related technologies, energy storage systems include multiple compartments, each housing battery devices, and each compartment is equipped with a fire suppression system and a fire control module. However, the fire control module occupies internal space within the compartment, thus affecting the number of battery devices that can be arranged within it, and consequently, the volumetric energy density of the energy storage system.

[0081] In view of this, to address the issue of the fire control module occupying space within the storage compartment and affecting the volumetric energy density of the energy storage system, some embodiments of this application provide an energy storage system. The energy storage system includes multiple battery devices, a first compartment, a second compartment, a first fire-fighting mechanism, a second fire-fighting mechanism, and a fire control module. Battery devices are housed in both the first and second compartments. The first fire-fighting mechanism is located within the first compartment. The second fire-fighting mechanism is located within the second compartment. The fire control module is located within either the first or second compartment and is communicatively connected to both the first and second fire-fighting mechanisms to control their operation.

[0082] In the above scheme, the fire control module can control the first fire-fighting mechanism and the second fire-fighting mechanism respectively, and the fire control module is set in one of the first and second compartments. On the one hand, it can improve the integration of fire control of the energy storage system, which is conducive to cost control and easy maintenance of the fire control module; on the other hand, it can reduce the space occupied by the fire control module in the internal space of the energy storage system, so that the energy storage system can arrange more battery devices, which in turn is conducive to improving the volumetric energy density of the energy storage system.

[0095] In some embodiments, the energy storage system 1000 further includes a control module 60, which performs electrical control on the battery devices 100 in the first compartment 200 and the battery devices 100 in the second compartment 300. Electrical control refers to low-voltage communication control.

[0096] Optionally, the entire control module 60 is housed within the first compartment 200. Optionally, the entire control module 60 is housed within the second compartment 300. Optionally, the control module 60 includes multiple control units, some of which are housed within the first compartment 200 and others within the second compartment 300. The multiple control units jointly provide electrical control over the battery device 100 within the first compartment 200 and the second compartment 300.

[0097] In some embodiments, the energy storage system 1000 further includes a converter 70, which is a device connecting an external device and the battery device 100. The external device may be a power grid, electrical appliances, etc. Generally, when the energy storage system 1000 is charging, the converter 70 acts as a rectifier to convert electrical energy from AC power on the AC side to DC power and store it in the battery device 100. When the energy storage system 1000 is discharging, the converter 70 acts as an inverter to convert the electrical energy stored in the battery device 100 from DC power on the DC side to AC power and supply it to the external device.

[0098] Optionally, the converter 70 may be entirely housed within the first compartment 200. Optionally, the converter 70 may be entirely housed within the second compartment 300. Optionally, the converter 70 may include multiple converters, with some of the converters housed within the first compartment 200 and others within the second compartment 300. Optionally, the converter 70 may be located outside the compartment.

[0099] The energy storage system 1000 includes a fire control module 30, which is used to control the fire-related electrical components of the first compartment 200 and the second compartment 300.

[0100] The number of fire control modules 30 is one, and the fire control module 30 is disposed in one of the first compartment 200 and the second compartment 300. For example, the first compartment 200 and the second compartment 300 are stacked along the height direction z, with the first compartment 200 located above the second compartment 300, and the fire control module 30 disposed in the second compartment 300.

[0101] The energy storage system 1000 has a fire-fighting mechanism. In some embodiments, a first fire-fighting mechanism 10 is provided in the first compartment 200, and a second fire-fighting mechanism 20 is provided in the second compartment 300. Both the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 are communicatively connected to the fire control module 30 and are both controlled by the fire control module 30 to release fire-fighting media under the control of the fire control module 30 to extinguish fires in their respective compartments.

[0102] In some embodiments, the fire-fighting medium released by the first fire-fighting agency 10 and the fire-fighting medium released by the second fire-fighting agency 20 may be the same or different. The fire-fighting medium is an extinguishing agent, which may include water, foam, dry powder, carbon dioxide, clean gas, wet chemical extinguishing agents, aerosols, sand, etc.

[0103] For example, both the first fire-fighting unit 10 and the second fire-fighting unit 20 can release aerosols. Both the first fire-fighting unit 10 and the second fire-fighting unit 20 are aerosol extinguishing devices. The aerosol extinguishing device can respond to a fire signal to activate its ignition device, thereby causing a chemical reaction or physical change in the chemical agents inside the device to release aerosols. Optionally, the aerosol extinguishing device can meet the EN15276 standard.

[0104] Optionally, each compartment includes a battery compartment 80 and an electrical compartment 90. The battery compartment 80 houses the battery units 100, and the electrical compartment 90 houses electrical components. These electrical components may include electrical components related to the energy storage system 1000, such as a control module 60, a converter 70, and a fire control module 30. The battery compartment 80 includes multiple sub-compartments 81, each sub-compartment 81 housing a row of battery units 100, and each row of battery units 100 including multiple battery units 100 arranged along the height direction z. The electrical compartment 90 is located on one side of the multiple sub-compartments 81.

[0105] For example, please refer to Figures 2 and 3. The battery compartment 80 includes four sub-compartments 81, and the electrical compartment 90 is disposed on one side of the four sub-compartments 81. The first fire-fighting mechanism 10 is an aerosol fire extinguishing device. There are multiple aerosol fire extinguishing devices, each of which is disposed on the ceiling of the first compartment 200, and each sub-compartment 81 of the first compartment 200 is provided with at least one aerosol fire extinguishing device. The second fire-fighting mechanism is also an aerosol fire extinguishing device. There are multiple aerosol fire extinguishing devices, each of which is disposed on the ceiling of the second compartment 300, and each sub-compartment 81 of the second compartment 300 is provided with at least one aerosol fire extinguishing device. The electrical compartment 90 of the first compartment 200 is provided with a wiring harness for communication connection between the first fire-fighting mechanism 10 and the fire control module 30. The battery compartment 80 of the second compartment 300 is provided with a second fire-fighting mechanism 20, and the electrical compartment 90 of the second compartment 300 is provided with a fire control module 30.

[0106] In the above scheme, the fire control module 30 can control the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 respectively, and the fire control module 30 is set in one of the first compartment 200 and the second compartment 300. On the one hand, it can improve the integration of fire control of the energy storage system 1000, which is conducive to cost control and easy maintenance of the fire control module 30; on the other hand, it can reduce the space occupied by the fire control module 30 in the internal space of the energy storage system 1000, so that the energy storage system 1000 can be equipped with more battery devices 100, which is conducive to improving the volumetric energy density of the energy storage system 1000.

[0107] According to some embodiments of this application, the first compartment 200 and the second compartment 300 are stacked along the height direction z, with the first compartment 200 located above the second compartment 300, and the fire control module 30 disposed inside the second compartment 300.

[0108] In some embodiments of this application, the first compartment 200 and the second compartment 300 are stacked along the height direction z, with the second compartment 300 located below the first compartment 200. Generally, the second compartment 300 is deployed on the ground. The fire control module 30 is disposed within the second compartment 300, such that the height of the fire control module 30 is lower than the height of the fire control module 30 disposed within the first compartment 200.

[0109] For example, the fire control module 30 is installed in the electrical compartment 90 of the second compartment 300. When maintenance of the fire control module 30 is required, the compartment door of the second compartment 300 corresponding to the electrical compartment 90 can be opened, and the fire control module 30 can be directly inspected and maintained without having to climb up.

[0110] In the above scheme, by setting the fire control module 30 in the lower position of the second compartment 300, the installation and maintenance difficulty of the fire control module 30 can be reduced, and the deployment and maintenance convenience of the energy storage system 1000 can be effectively improved. On the other hand, since the fire control module 30 does not occupy the internal space of the first compartment 200, more battery devices 100 can be arranged in the first compartment 200, which is conducive to improving the volumetric energy density of the energy storage system 1000.

[0111] According to some embodiments of this application, a first fire-fighting mechanism 10 is used to release aerosols, and a second fire-fighting mechanism 20 is used to release aerosols.

[0112] In some embodiments, the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 may include an aerosol extinguishing device. The aerosol extinguishing device is capable of releasing an aerosol extinguishing agent. The aerosol extinguishing agent may be a extinguishing medium that inhibits combustion reaction by releasing ultrafine solid or liquid particles suspended in a gas to form an aerosol state.

[0113] For example, the fire control module 30 can give instructions to the aerosol extinguishing device, and the aerosol extinguishing device responds to the instructions to activate the ignition device of the aerosol extinguishing device, thereby causing the chemical agents inside the device to undergo a chemical reaction or physical change to release aerosol.

[0114] In the above scheme, the fire-fighting medium released by the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 is set as an aerosol. On the one hand, it can quickly extinguish the fire source and reduce the risk of further combustion of the energy storage system 1000. On the other hand, it can reduce the risk of short circuit between battery devices 100 caused by the fire-fighting medium, thereby improving the reliability of the energy storage system 1000.

[0115] According to some embodiments of this application, the energy storage system 1000 further includes a first detector 11 and a second detector 21. The first detector 11 is disposed within the first compartment 200 and is used to detect a first fire signal within the first compartment 200. The second detector 21 is disposed within the second compartment 300 and is used to detect a second fire signal within the second compartment 300. The fire control module 30 is communicatively connected to the first detector 11 and the second detector 21 and is configured to control the first fire-fighting mechanism 10 to operate in response to the first fire signal and to control the second fire-fighting mechanism 20 to operate in response to the second fire signal.

[0116] The first detector 11 is a structural component installed inside the first compartment 200. It is used to detect the first fire signal inside the first compartment 200 and transmit the first fire signal to the fire control module 30, so that the fire control module 30 responds to the first fire signal to control the first fire-fighting mechanism 10 to work and realize fire extinguishing inside the first compartment 200.

[0117] The second detector 21 is a structural component installed inside the second compartment 300. It is used to detect the second fire signal inside the second compartment 300 and transmit the second fire signal to the fire control module 30, so that the fire control module 30 responds to the second fire signal to control the second fire-fighting mechanism 20 to work and realize fire extinguishing inside the second compartment 300.

[0118] A fire signal can be understood as various phenomena and indicators that reflect the existence and related information of a fire, such as smoke, high temperature, and flames. For example, the first detector 11 and the second detector 21 may include smoke detectors, also known as smoke-sensitive fire detectors, smoke detectors, smoke probes, and smoke sensors. Smoke detectors can detect the smoke concentration inside the compartment for fire prevention. For example, the first detector 11 and the second detector 21 may include temperature detectors. Temperature detectors can be used to detect the ambient temperature inside the compartment, the temperature of structural components inside the compartment, the temperature of the battery device 100 inside the compartment, etc. When the detected temperature value exceeds a threshold, it can trigger the first fire-fighting mechanism 10 to operate. For example, the first detector 11 and the second detector 21 may include flame detectors. Flame detectors can detect that when a substance burns, it produces smoke and releases heat, as well as visible or invisible light radiation not present in the atmosphere.

[0119] The specific location of the detector relative to the compartment is not limited; the detector can be installed on the top wall, side wall, or bottom wall of the compartment. For example, the first detector 11 can be installed on the ceiling of the first compartment 200, deployed in the battery compartment 80. The second detector 21 can be installed on the ceiling of the second compartment 300, deployed in the battery compartment 80.

[0120] Optionally, the wiring harness of the first detector 11 for communicating with the fire control module 30 can be installed in the electrical compartment 90 of the first compartment 200.

[0121] In the above scheme, the fire control module 30 is communicatively connected to the first detector 11 and the second detector 21, so that the fire control module 30 can respond to the first fire signal or the second fire signal to control the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 to work respectively, thereby accurately extinguishing the fire at the fire point, realizing the rapid extinguishing of the flames, and thus improving the reliability of the energy storage system 1000.

[0122] According to some embodiments of this application, please refer to Figures 1 and 5. Figure 5 is a schematic diagram of the first connector 40, the second connector 50 and the fire control module 30 in some embodiments of this application.

[0123] The energy storage system 1000 also includes a first connector 40 and a second connector 50. The first connector 40 is connected to the first fire-fighting mechanism 10 and the first detector 11 via a first wiring harness 41. The second connector 50 is connected to the fire control module 30 via a second wiring harness 51, and the first connector 40 and the second connector 50 are plugged into each other.

[0124] In some embodiments, the first connector 40 and the second connector 50 are mating electrical connection structures that achieve a communication connection through quick-connect mating. Exemplarily, the first connector 40 and the second connector 50 are a socket and a plug for achieving a communication connection.

[0125] In some embodiments, the first wire harness 41 and the second wire harness 51 can be used for signal transmission and / or electrical power transmission.

[0126] Before the deployment of the energy storage system 1000, the first fire-fighting mechanism 10 and the first detector 11 are connected to the first connector 40 via the first wiring harness 41, and the fire control module 30 is adjacent to the second connector 50 via the second wiring harness 51. During the deployment of the energy storage system 1000, the first fire-fighting mechanism 10 and the first detector 11 can be connected to the fire control module 30 through the quick plugging and unplugging of the first connector 40 and the second connector 50.

[0127] For example, before the energy storage system 1000 is deployed, the wiring harness of the first fire-fighting mechanism 10 and the wiring harness of the first detector 11 are pre-crimped to the first connector 40, and the wiring harness of the fire control module 30 used for communication with the first fire-fighting mechanism 10 and the second detector 21 is pre-crimped to the second connector 50, so that the wiring harness can be used immediately by quickly plugging and unplugging the first connector 40 and the second connector 50 during the deployment of the energy storage system 1000.

[0128] In the above scheme, by setting up the first connector 40 and the second connector 50 that are mutually plugged in, the communication connection between the fire control module 30 and the first fire-fighting mechanism 10 and the first detector 11 can be quickly realized, reducing the installation and commissioning procedures for users on site, reducing the wiring difficulty between the fire communication lines between the first compartment 200 and the second compartment 300, thereby improving the deployment efficiency of the energy storage system 1000.

[0129] According to some embodiments of this application, the second connector 50 is connected to the second detector 21 via the second wiring harness 51.

[0130] In some embodiments, the second detector 21 is connected to the second connector 50 via the second wiring harness 51. Exemplarily, before the energy storage system 1000 is deployed, the wiring harness of the second detector 21 is pre-crimped to the second connector 50. During the deployment of the energy storage system 1000, a loop can be formed between the first detector 11, the second detector 21 and the fire control module 30 through the rapid insertion and mating of the first connector 40 and the second connector 50.

[0131] In the above scheme, the second detector 21 is connected to the second connector 50 through the second wiring harness 51, which enables the first detector 11, the second detector 21 and the fire control module 30 to form a loop, simplifying the layout of communication lines between the first detector 11 and the fire control module 30, and between the second detector 21 and the fire control module 30, thereby reducing the space occupied by the communication lines in the internal space of the energy storage system 1000, allowing the energy storage system 1000 to accommodate more battery devices 100, which in turn helps to improve the volumetric energy density of the energy storage system 1000.

[0132] According to some embodiments of this application, please refer to Figure 5. The first wiring harness 41 includes a first conductor 410, a second conductor 411, and a third conductor 412. The first conductor 410 is connected to the first fire-fighting mechanism 10, and the second conductor 411 and the third conductor 412 are respectively connected to the first detector 11. The second wiring harness 51 includes a fourth conductor 510, a fifth conductor 511, and a sixth conductor 512. The fourth conductor 510 is connected to the fire control module 30, the fifth conductor 511 is connected to the fire control module 30, and the sixth conductor 512 is connected to the second detector 21. The fire control module 30 and the second detector 21 are communicatively connected. When the first connector 40 and the second connector 50 are plugged in, the first conductor 410 and the fourth conductor 510 are interconnected; the second conductor 411 and the fifth conductor 511 are interconnected; and the third conductor 412 and the sixth conductor 512 are connected, so that the first detector 11, the fire control module 30, and the second detector 21 form a loop.

[0133] Please refer to Figure 5. The first wire 410 is connected to the first fire-fighting mechanism 10, and the fourth wire 510 is connected to the fire control module 30. When the first connector 40 and the second connector 50 are plugged in, the first wire 410 and the fourth wire 510 are connected. The fire control module 30 can send commands to the first fire-fighting mechanism 10 and / or supply power to the first fire-fighting mechanism 10 through the first wire 410 and the fourth wire 510 so that the first fire-fighting mechanism 10 can release the fire-fighting medium.

[0134] Please refer to Figure 5. The second fire-fighting mechanism 20 and the fire control module 30 are connected via a wiring harness.

[0135] Please refer to Figure 5. The second wire 411 and the third wire 412 are respectively connected to the first detector 11. The first detector 11 includes a first smoke detector 110 and a first heat detector 111 connected in series. The fifth wire 511 is connected to the fire control module 30, and the sixth wire 512 is connected to the second detector 21. The fire control module 30 is communicatively connected to the second detector 21 (including the second smoke detector 210 and the second heat detector 211 connected in series). When the first connector 40 and the second connector 50 are plugged in, the second wire 411 and the fifth wire 511 are connected to each other, and the third wire 412 and the sixth wire 512 are connected, so that the first detector 11, the fire control module 30 and the second detector 21 form a loop. The fire control module 30 can receive the first fire signal and the second fire signal detected by the first detector 11 and the second detector 21 through this loop, so as to control the first fire-fighting mechanism 10 and the second fire-fighting mechanism 20 to release the fire-fighting medium respectively.

[0136] In the above scheme, the first connector 40 integrates the first wire 410, the second wire 411, and the third wire 412, and the second connector 50 integrates the fourth wire 510, the fifth wire 511, and the sixth wire 512. Through the quick plugging and unplugging of the first connector 40 and the second connector 50, the communication connection between the fire control module 30 and the fire-fighting components in the first compartment 200 can be quickly realized, reducing the installation and commissioning procedures for users on site, reducing the wiring difficulty between the fire communication lines between the first compartment 200 and the second compartment 300, thereby improving the deployment efficiency of the energy storage system 1000.

[0137] According to some embodiments of this application, the energy storage system 1000 further includes a first alarm 12 and a second alarm 22. The first alarm 12 is disposed within the first compartment 200 and is used to issue an alarm signal in response to a first fire signal. The second alarm 22 is disposed within the second compartment 300 and is used to issue an alarm signal in response to a second fire signal. A first connector 40 is connected to the first alarm 12 via a first wiring harness 41, and a second connector 50 is connected to the second alarm 22 via a second wiring harness 51. The second alarm 22 is communicatively connected to the fire control module 30.

[0138] In some embodiments, each compartment is equipped with an alarm to alert personnel in the event of a fire; that is, the first compartment 200 is equipped with a first alarm 12 and the second compartment 300 is equipped with a second alarm 22.

[0139] Optionally, the alarm can be an audible and visual alarm, a purely sound alarm, a purely light alarm, or a graphic display alarm, etc. For example, each compartment is equipped with an audible and visual alarm, which provides a warning through sound and flashing lights.

[0140] Optionally, the first alarm 12 is installed in the electrical compartment 90 of the first compartment 200, and the second alarm 22 is installed in the electrical compartment 90 of the second compartment 300. The second alarm 22 is connected to the fire control module 30 via a wiring harness.

[0141] Please refer to Figure 5. The first alarm 12 is connected in series with the first detector 11, and the second alarm 22 is connected in series with the second detector 21. When the first connector 40 and the second connector 50 are plugged in, the second wire 411 and the fifth wire 511 are connected to each other, and the third wire 412 and the sixth wire 512 are connected, so that the first detector 11, the first alarm 12, the fire control module 30, the second detector 21 and the second alarm 22 form a loop. The fire control module 30 can receive the first fire signal and the second fire signal detected by the first detector 11 and the second detector 21 through this loop, and control the first alarm 12 and the second alarm 22 to work respectively.

[0142] In the above scheme, by setting up the first alarm 12 and the second alarm 22, personnel can be alerted during firefighting, shortening personnel response time and improving firefighting efficiency. At the same time, the first alarm 12 can quickly achieve communication connection with the fire control module 30 through the first wiring harness 41 and the first connector 40, reducing the on-site installation and commissioning procedures for users and improving the deployment efficiency of the energy storage system 1000. Furthermore, the second alarm 22 is connected to the second connector 50 through the second wiring harness 51, forming a loop between the first alarm 12, the fire control module 30, and the second alarm 22. This simplifies the layout of communication lines between the first alarm 12 and the fire control module 30, and between the second alarm 22 and the fire control module 30, thereby reducing the space occupied by communication lines within the energy storage system 1000. This allows the energy storage system 1000 to accommodate more battery devices 100, which in turn improves the volumetric energy density of the energy storage system 1000.

[0143] According to some embodiments of this application, please refer to FIG5. The first detector 11 includes a first smoke detector 110 and a first heat detector 111, and the second detector 21 includes a second smoke detector 210 and a second heat detector 211. The first wiring harness 41 includes signal lines for the first fire-fighting mechanism 10, the first smoke detector 110, the first heat detector 111, and the first alarm 12; and / or, the second wiring harness 51 includes signal lines for the second smoke detector 210, the second heat detector 211, and the second alarm 22.

[0144] Smoke detectors, also known as smoke-sensing fire detectors, smoke detectors, smoke probes, and smoke sensors, can detect the concentration of smoke inside a compartment for fire prevention.

[0145] Temperature detectors can be used to detect the ambient temperature inside the chamber, the temperature of structural components inside the chamber, the temperature of the battery device 100 inside the chamber, etc. When the detected temperature value exceeds the threshold, it can trigger the fire-fighting mechanism to work.

[0146] In some embodiments, the first wiring harness 41 includes multiple signal lines, such as signal lines for the first fire-fighting mechanism 10, the first smoke detector 110, the first heat detector 111, and the first alarm 12. These multiple signal lines can be crimped to the first connector 40 before the energy storage system 1000 is deployed.

[0147] In some embodiments, the second wiring harness 51 includes multiple signal lines, such as the signal lines of the second smoke detector 210, the second temperature detector 211, and the second alarm 22. These multiple signal lines can be crimped to the second connector 50 before the energy storage system 1000 is deployed.

[0148] In the above scheme, by combining smoke detectors and temperature detectors, accurate fire signals can be obtained by combining smoke characteristic information and temperature information, thereby comprehensively judging the fire situation and accurately controlling the release of fire-fighting media by the fire-fighting agency. This reduces the risk of the fire-fighting media affecting the reliability of the energy storage system due to misjudgment, thus improving the reliability of the energy storage system. At the same time, the signal lines of the first fire-fighting agency 10, the first smoke detector 110, the first temperature detector 111, and the first alarm 12 are integrated into the first connector 40 through the first wiring harness 41, and the signal lines of the second smoke detector 210, the second temperature detector 211, and the second alarm 22 are integrated into the second connector 50 through the second wiring harness. With the quick plugging and unplugging of the first connector 40 and the second connector 50, the communication connection between the fire control module 30 and the fire-fighting components in the first compartment 200 can be quickly realized, reducing the installation and debugging procedures for users on site and reducing the wiring difficulty between the fire communication lines of the first compartment 200 and the second compartment 300, thereby improving the deployment efficiency of the energy storage system 1000.

[0149] According to some embodiments of this application, please refer to FIG6, which is a schematic diagram of the internal structure of the first compartment 200 in some embodiments of this application.

[0150] The first chamber 200 is provided with a first vent, and the first vent is provided with a first fan 13, which is used to exhaust the gas inside the first chamber 200. The energy storage system 1000 also includes a third detector 14, which is disposed inside the first chamber 200 and is used to detect the gas signal inside the first chamber 200. The first fan 13 is configured to start in response to the gas signal. The first connector 40 is connected to the third detector 14 through a first wiring harness 41.

[0151] The first vent is a through-hole structure located in the wall of the first chamber 200, used to connect the interior of the first chamber 200 with the outside, allowing for gas circulation. A first fan 13 is located at the first vent to close it. When the first fan 13 is not operating, the risk of fluids, such as gases and liquids, entering or exiting the first chamber 200 through the first vent is reduced. When the first fan 13 is operating, it can exhaust the gas inside the first chamber 200 to the outside.

[0152] The third detector 14 can be a combustible gas detector, which can be a detector that responds to the concentration of one or more combustible gases. Optionally, the third detector 14 includes a hydrogen detector, which can be configured in accordance with NFPA 855 standards.

[0153] The phrase "the third detector 14 is used to detect gas signals within the first chamber 200, and the first fan 13 is configured to start in response to the gas signal" can be understood as follows: when the third detector 14 detects that the concentration of combustible gas inside the first chamber 200 exceeds a threshold, the first fan 13 is activated to expel the gas from the first chamber 200 and reduce the concentration of combustible gas within the first chamber 200. In some embodiments, the first vent may be located on the side wall of the first chamber 200. In other embodiments, the first vent may be located on the top wall of the first chamber 200.

[0154] Optionally, louvers may be provided on the wall of the first chamber 200, which open when the first fan 13 is started to connect the first chamber 200 with the outside.

[0155] Optionally, the second chamber 300 may be equipped with a second fan 23 and a fourth detector 24, the fourth detector 24 being used to detect gas signals within the second chamber 300, and the second fan 23 being configured to start in response to the gas signals.

[0156] In some embodiments, the first connector 40 enables the third detector 14 to communicate with the fire control module 30 when the first wiring harness 41 is connected to the third detector 14 so that the first connector 40 and the second connector 50 can be plugged into each other.

[0157] In the above scheme, the concentration of combustible gas inside the first chamber 200 is detected by the third detector 14. Combined with the operation of the first fan 13, this effectively removes the combustible gas from inside the first chamber 200, reducing the risk of explosion of the energy storage system 1000 and improving its reliability. Simultaneously, the third detector 14 and the first fan 13 are connected to the first connector 40 via the first wiring harness 41, enabling rapid communication with the fire control module 30. This reduces on-site installation and commissioning procedures for users, thereby improving the deployment efficiency of the energy storage system 1000.

[0158] According to some embodiments of this application, the first wiring harness 41 includes the signal line of the third detector.

[0159] For example, please refer to Figure 5. The first wiring harness 41 includes a seventh conductor 413, which is the signal line of the third detector 14. The second wiring harness 51 includes an eighth conductor 513, which is connected to the fire control module 30. When the first connector 40 and the second connector 50 are plugged in, the seventh conductor 413 and the eighth conductor 513 are interconnected.

[0160] Please refer to Figure 5. The third detector 14 is connected to the first connector 40 via the seventh wire 413, and the fire control module 30 is connected to the second connector 50 via the eighth wire 513. When the first connector 40 and the second connector 50 are plugged in, the seventh wire 413 and the eighth wire 513 are connected to each other, so that the fire control module 30 and the third detector 14 can communicate and achieve signal transmission or power transmission.

[0161] For example, the energy storage system 1000 further includes a first controller 15 and a second controller 25. The first controller 15, the first detector 11, and the first alarm 12 are connected in series. The first controller 15 is communicatively connected to the third detector 14 and the first fan 13 via a wiring harness. The second controller 25, the second detector 21, and the second alarm 22 are connected in series. The second controller 25 is communicatively connected to the fourth detector 24 and the second fan 23 via a wiring harness. When the first connector 40 and the second connector 50 are plugged in, the fire control module 30 can supply power to the third detector 14. The fire control module 30 receives the gas signal detected by the third detector 14 through the first controller 15 to control the start of the first fan 13. The fire control module 30 receives the gas signal detected by the fourth detector 24 through the second controller 25 to control the start of the second fan 23. Optionally, both the first controller 15 and the second controller 25 are dual-input / output modules.

[0162] The above solution integrates the signal line of the third detector 14 into the first connector 40 through the first wiring harness 41. With the quick plugging and unplugging of the first connector 40 and the second connector 50, the communication connection between the fire control module 30 and the third detector 14 can be quickly realized, reducing the installation and debugging procedures for users on site and reducing the wiring difficulty between the fire communication lines between the first compartment 200 and the second compartment 300, thereby improving the deployment efficiency of the energy storage system 1000.

[0163] According to some embodiments of this application, please refer to Figures 7 and 8. Figure 7 is a schematic diagram of the first connector 40 in some embodiments of this application, and Figure 8 is a schematic diagram of the second connector 50 in some embodiments of this application.

[0164] One of the first connector 40 and the second connector 50 is provided with a foolproof protrusion 42, and the other is provided with a foolproof groove 52. The foolproof protrusion 42 is used to cooperate with the foolproof groove 52.

[0165] The first connector 40 and the second connector 50 are plug-in connectors, which achieve conduction between the wire harnesses by plugging them into each other.

[0166] In some embodiments, the first connector 40 is provided with a foolproof protrusion 42 and the second connector 50 is provided with a foolproof groove 52. When the first connector 40 and the second connector 50 are correctly mated, the foolproof protrusion 42 can be inserted into the foolproof groove 52. When the first connector 40 and the second connector 50 are incorrectly mated, the foolproof protrusion 42 is interfered with by the surface of the second connector 50, making it impossible for the first connector 40 and the second connector 50 to be mated.

[0167] For example, the first connector 40 has a rectangular insertion protrusion 43, and the second connector 50 has a recessed insertion groove 53, which communicates with a foolproof groove 52. A foolproof protrusion 42 is formed on one side of the insertion protrusion 43 along its width direction y. When the insertion protrusion 43 is correctly inserted into the recessed insertion groove 53, the foolproof protrusion 42 can be inserted into the foolproof groove 52; otherwise, the foolproof protrusion 42 cannot be inserted into the foolproof groove 52, and the first connector 40 and the second connector 50 fail to mate.

[0168] Optionally, the housing of the first connector 40 is provided with a first bolt hole 44, and the housing of the second connector 50 is provided with a second bolt hole 54. When the first connector 40 and the second connector 50 are inserted into place, they can be fastened with a nut by passing a bolt through the first bolt hole 44 and the second bolt hole 54, thereby achieving the fastening of the first connector 40 and the second connector 50.

[0169] In the above solution, by setting mutually cooperating anti-mistake protrusions 42 and anti-mistake grooves 52 between the first connector 40 and the second connector 50, the risk of incorrect connection of the first connector 40 and the second connector 50 can be reduced, thereby improving the deployment efficiency of the energy storage system 1000.

[0170] According to some embodiments of this application, please refer to FIG1, the first connector 40 and the second connector 50 are both disposed on the first compartment 200.

[0171] In some embodiments, when the energy storage system 1000 is deployed, both the first connector 40 and the second connector 50 are located in the first housing 200.

[0172] In the above solution, by setting both the first connector 40 and the second connector 50 in the first compartment 200, the space occupied by the first connector 40 and the second connector 50 in the second compartment 300 can be reduced, as well as the risk of interference between the first connector 40 and the second connector 50 and other structural components in the second compartment 300 can be reduced, making it easier to arrange the battery device 100 and other electrical components in the second compartment 300.

[0173] According to some embodiments of this application, the first compartment 200 and the second compartment 300 are stacked along the height direction z, the first compartment 200 is located above the second compartment 300, the bottom wall of the first compartment 200 is provided with a first through hole, the top wall of the second compartment 300 is provided with a second through hole, and a portion of the second wire harness 51 passes through the second through hole and the first through hole.

[0174] In some embodiments, the first compartment 200 and the second compartment 300 are stacked along the height direction z. The bottom wall of the first compartment 200 faces the top wall of the second compartment 300. The bottom wall of the first compartment 200 is provided with a first through hole, and the top wall of the second compartment 300 is provided with a second through hole. The first through hole and the second through hole allow portions of the second connector 50 and the second wiring harness 51 to pass through, so that the second connector 50 is connected to the fire control module 30 and related components located in the second compartment 300 through the second wiring harness 51.

[0175] Optionally, the first through hole and the second through hole can be coaxially arranged. Alternatively, the axes of the first through hole and the second through hole can be spaced apart from each other.

[0176] In the above scheme, by setting a first through hole on the bottom wall of the first compartment 200 and a second through hole on the top wall of the second compartment 300, the wiring layout of the second wiring harness 51 can be facilitated, which is conducive to improving the deployment efficiency of the energy storage system 1000.

[0177] According to some embodiments of this application, the first compartment 200 and the second compartment 300 are stacked along the height direction z, and at least one of the dimensions of the first compartment 200 and the second compartment 300 along the height direction z is smaller than the dimensions of a standard container along the height direction z.

[0178] In some embodiments, the first compartment 200 and the second compartment 300 are stacked along the height direction z.

[0179] Optionally, the height dimensions of the first compartment 200 and the second compartment 300 are both smaller than the height dimensions of a standard container. For example, taking a 20-foot standard container as an example, the height dimension z of the standard container can be 2896mm, and the height dimensions z of both the first compartment 200 and the second compartment 300 are smaller than 2896mm.

[0180] Optionally, one of the height dimensions of the first compartment 200 and the second compartment 300 is smaller than the height dimension of a standard container, and the other is equal to or greater than the height dimension of a standard container.

[0181] In the above scheme, by setting the height of one of the first compartment 200 and the second compartment 300 to be less than the height of a standard container, on the one hand, one of the first compartment 200 and the second compartment 300 can be transported independently, meeting the transportation requirements of the energy storage system 1000; on the other hand, since the height of one of the first compartment 200 and the second compartment 300 is smaller, the diffusion time of the fire-fighting medium released by the fire-fighting agency can be shortened, thereby improving the efficiency of fire extinguishing and thus improving the reliability of the energy storage system 1000.

[0182] According to some embodiments of this application, the energy storage system 1000 further includes a control module 60, which is used to electrically control a plurality of battery devices 100 in the first compartment 200 and the second compartment 300. The control module 60 is housed in one of the first compartment 200 and the second compartment 300.

[0183] The energy storage system 1000 also includes a control module 60, which electrically controls the battery devices 100 in the first compartment 200 and the second compartment 300. The electrical control refers to low-voltage communication control. Optionally, the entire control module 60 is housed within the first compartment 200. Optionally, the entire control module 60 is housed within the second compartment 300.

[0184] In some embodiments, the plurality of battery devices 100 include at least one battery cluster. A battery cluster may include a plurality of battery devices 100 connected in series. For example, a battery cluster may include four or eight battery devices 100 connected in series.

[0185] Optionally, the energy storage system 1000 also includes a main control module. Both the first compartment 200 and the second compartment 300 are equipped with a main control module. The main control module of the first compartment 200 can be used for high-voltage electrical connection with the battery clusters of the first compartment 200, and the main control module of the second compartment 300 can be used for high-voltage electrical connection with the battery clusters of the second compartment 300. Optionally, the main control module can be connected to the control module 60 via low-voltage communication.

[0186] In the above scheme, the control module 60 electrically controls all battery devices 100 in the energy storage system 1000, integrating the first compartment 200 and the second compartment 300 into a single energy storage system 1000 to facilitate the control of energy storage and discharge. Simultaneously, the battery devices 100 in both compartments are controlled by the same control module 60, which reduces the space occupied by the control module 60 within the energy storage system 1000 and improves the volumetric energy density of the energy storage system 1000.

[0187] According to some embodiments of this application, the sum of the dimensions of the first compartment 200 along the height direction z and the dimensions of the second compartment 300 along the height direction z is greater than or equal to the dimensions of a standard container along the height direction z.

[0188] In some embodiments, the dimensions of the first storage unit 200 and the second storage unit 300 along the height direction z are both smaller than the dimensions of a standard container along the height direction z. When the two storage units are stacked along the height direction z, the sum of the height dimensions of the two storage units can be equal to or greater than the height dimension of a standard container.

[0189] For example, the standard container is a 20-foot standard container with a height of 2896 mm. The sum of the dimensions of the first compartment 200 along the height direction z and the dimensions of the second compartment 300 along the height direction z is equal to 2896 mm.

[0190] In the above scheme, by setting the sum of the height dimensions of the two compartments to be greater than or equal to the height dimension of a standard container, the energy storage system 1000 can have a larger dimension in the height direction z, which is beneficial to increase the space of the first compartment 200 and the second compartment 300 in the height direction z, so that more battery devices 100 can be installed in the first compartment 200 and the second compartment 300 in the height direction z, thereby increasing the volumetric energy density of the energy storage system 1000.

[0191] According to some embodiments of this application, the dimensions of the first compartment 200 and the second compartment 300 along their length direction x are consistent with the dimensions of the standard container along their length direction x, and the dimensions of the first compartment 200 and the second compartment 300 along their width direction y are consistent with the dimensions of the standard container along their width direction y.

[0194] In the above scheme, the dimensions of each compartment in the length direction x and width direction y are consistent with those of a standard container. This makes the floor area of ​​the first compartment 200 and the second compartment 300 the same as that of a standard container, which can reduce the transportation difficulty of the first compartment 200 and the second compartment 300 and reduce transportation costs.

[0195] According to some embodiments of this application, the standard container is a 20-foot standard container.
