Technical Field

[0002] This application relates to the field of batteries, and more specifically, to an energy storage system, a method for disassembling the energy storage system, and a method for installing the 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. As devices that cyclically store and release electrical energy, energy storage systems store electrical energy within the system or supply the stored energy to electrical devices through charging or discharging. 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 their performance, facilitating their transportation is also a crucial issue. Therefore, how to facilitate the transportation of energy storage systems is a continuous technical challenge in energy storage technology. Summary of the Invention

[0005] The purpose of this application is to provide an energy storage system, a method for disassembling the energy storage system, and a method for installing the energy storage system, which can improve the transportation convenience of the energy storage system.

[0006] In a first aspect, embodiments of this application provide an energy storage system, the energy storage system including a first compartment, a first battery device, a second compartment, a second battery device, a thermal management module, and a piping system. The first compartment houses the first battery device, and the first battery device includes a first thermal management component. The second compartment houses the second battery device, the first compartment and the second compartment are arranged along a first direction, and the second battery device includes a second thermal management component. The piping system connects the thermal management module, the first thermal management component, and the second thermal management component. The thermal management module is used to manage the temperature of the first battery device and the second battery device. The piping system includes a first pipe and a second pipe. The first pipe is connected to the thermal management module and is at least partially housed in the first compartment, and the second pipe is connected to the second thermal management component and is at least partially housed in the second compartment. The first pipe and the second pipe are detachably connected.

[0007] In the above technical solution, by setting up a first compartment and a second compartment, the first battery device is housed in the first compartment, and the second battery device is housed in the second compartment, which is beneficial to improving the capacity and energy density of the energy storage system. This energy storage system uses a single thermal management module to manage the thermal of both the first and second battery devices, which helps reduce the number of thermal management modules, lowers the production cost of the energy storage system, reduces the space occupied by the energy storage system, and improves the volumetric energy density of the energy storage system. The first tube is connected to the thermal management module, and the second tube is connected to the second thermal management component. The first and second tubes are detachably connected. On the one hand, this allows the first heat exchange medium to flow from the thermal management module to the second thermal management component or vice versa, thereby achieving thermal management of the second battery device. On the other hand, the detachable connection of the first and second tubes allows them to be separated during transportation, facilitating the separate transport of the first and second compartments, reducing transportation difficulty and costs. In addition, by making the first pipe body and the second pipe body detachably connected, the air tightness of the first pipe body and the second pipe body can be tested separately when testing air tightness, which can reduce the time for tracing leaks and quickly determine the leak point.

[0008] As an optional technical solution in this application embodiment, the pipeline system further includes a connecting pipe, and the first pipe body and the second pipe body are detachably connected through the connecting pipe.

[0009] In the above technical solution, by setting a connecting pipe, one end of which is detachably connected to the first pipe body and the other end of which is detachably connected to the second pipe body, the difficulty of separating the first and second pipe bodies is reduced. Furthermore, by making the first and second pipe bodies detachably connected via the connecting pipe, the airtightness of the first pipe body, the second pipe body, and the connecting pipe can be tested separately during airtightness testing, reducing the time required to locate leaks and quickly identifying the leak point.

[0010] As an optional technical solution in this application embodiment, the connecting pipe and the first pipe body are connected by a clamp; and / or the connecting pipe and the second pipe body are connected by a clamp.

[0011] In the above technical solution, the connecting pipe and the first pipe body are connected by clamps, which is simple and convenient, easy to assemble and disassemble, and has high reliability. The connecting pipe and the second pipe body are also connected by clamps, which is simple and convenient, easy to assemble and disassemble, and has high reliability.

[0012] As an optional technical solution in this application embodiment, the energy storage system includes a first sealing element, which seals the connecting pipe and the first pipe body; and / or the energy storage system includes a second sealing element, which seals the connecting pipe and the second pipe body.

[0013] In the above technical solution, by setting a first sealing element to seal the gap between the connecting pipe and the first pipe body, the risk of leakage of the first heat exchange medium from the connection point between the connecting pipe and the first pipe body is reduced. Similarly, by setting a second sealing element to seal the gap between the connecting pipe and the second pipe body, the risk of leakage of the first heat exchange medium from the connection point between the connecting pipe and the second pipe body is also reduced.

[0014] As an optional technical solution in this application embodiment, the connecting pipe and the first pipe body are quick-connected; and / or the connecting pipe and the second pipe body are quick-connected.

[0015] In the above technical solution, the quick-connect connection between the connecting pipe and the first pipe body allows for assembly and disassembly of the connecting pipe and the first pipe body without the need for tools, which improves the efficiency of assembly and disassembly. Similarly, the quick-connect connection between the connecting pipe and the second pipe body also allows for assembly and disassembly of the connecting pipe and the second pipe body without the need for tools, further improving the efficiency of assembly and disassembly.

[0016] As an optional technical solution in this application embodiment, the first pipe body includes a first flow-blocking device, which is configured to connect or disconnect the first pipe body and the connecting pipe. The second pipe body includes a second flow-blocking device, which is configured to connect or disconnect the second pipe body and the connecting pipe.

[0017] In the above technical solution, since the energy storage system needs to be debugged before leaving the factory, the first tube, connecting pipe, and second tube already contain the first heat exchange medium. When it is necessary to disassemble the connecting pipe, the first and second throttling devices can be closed first, thereby cutting off the first tube and connecting pipe, and cutting off the second tube and connecting pipe. In this way, the first heat exchange medium in the first and second tubes is less likely to leak during disassembly. During assembly, the connecting pipe is first connected to the first and second tubes, and then the first and second throttling devices are opened, so that the first tube and connecting pipe are connected, and the second tube and connecting pipe are connected, so as to realize the circulation of the first heat exchange medium.

[0018] As an optional technical solution in this application embodiment, the first flow-blocking device includes a valve or a self-sealing joint; and / or the second flow-blocking device includes a valve or a self-sealing joint.

[0019] In the above technical solutions, when the first flow-stopping device includes a valve, the first pipe body and the connecting pipe can be connected or disconnected by opening or closing the first flow-stopping device, and it can withstand greater pressure. When the first flow-stopping device includes a self-sealing joint, the first pipe body and the connecting pipe can be automatically connected during installation and automatically disconnected during disassembly. When the second flow-stopping device includes a valve, the second pipe body and the connecting pipe can be connected or disconnected by opening or closing the second flow-stopping device, and it can withstand greater pressure. When the second flow-stopping device includes a self-sealing joint, the second pipe body and the connecting pipe can be automatically connected during installation and automatically disconnected during disassembly.

[0020] As an optional technical solution in this application embodiment, the connecting pipe is provided with a vent and a discharge port, the vent being positioned higher than the discharge port; the vent is provided with a first switch configured to open or close the vent, and the discharge port is provided with a second switch configured to open or close the discharge port.

[0021] In the above technical solution, before disassembling the connecting pipe, the connecting pipe already contains the first heat exchange medium. In order to facilitate the disassembly of the connecting pipe, the vent can be opened first through the first switch to balance the air pressure inside and outside the connecting pipe, and then the exhaust port can be opened through the second switch to release the first heat exchange medium inside the connecting pipe.

[0022] As an optional technical solution in this application embodiment, the first tube has a first connecting end located in the first chamber, the second tube has a second connecting end located in the second chamber, and the connecting pipe is detachably connected to the first connecting end and the second connecting end; the first chamber has a first wall, the second chamber has a second wall, the first wall and the second wall are arranged opposite to each other along the first direction, and the connecting pipe passes through the first wall and the second wall.

[0023] In the above technical solution, the first connecting end of the first pipe body is housed within the first compartment, and the second connecting end of the second pipe body is housed within the second compartment. One end of the connecting pipe is detachably connected to the first connecting end, and the other end of the connecting pipe passes through the first wall and the second wall and is detachably connected to the second connecting end. During transportation, the connecting pipe can be detached from the first and second connecting ends. At this time, the first connecting end is housed within the first compartment, and the second connecting end is housed within the second compartment. When transporting the first and second compartments separately, the first and second connecting ends are less likely to interfere with the transportation equipment, which helps to reduce transportation difficulty and costs.

[0024] As an optional technical solution in this application embodiment, at least one of the first tube body, the second tube body, and the connecting tube includes a deformable tube.

[0025] In the above technical solution, by including at least one of the first tube body, the second tube body, and the connecting tube as a deformable tube, it is beneficial to absorb manufacturing errors and assembly errors, thereby facilitating the disassembly and installation of the connecting tube.

[0026] As an optional technical solution in this application embodiment, the connecting pipe includes a first pipe segment, a second pipe segment, and a third pipe segment. At least a portion of the first pipe segment is located in the first chamber and is detachably connected to the first pipe body. At least a portion of the third pipe segment is located in the second chamber and is detachably connected to the second pipe body. The second pipe segment connects the first pipe segment and the third pipe segment. The second pipe segment includes a deformable pipe.

[0027] In the above technical solution, the first pipe segment is at least partially located within the first compartment and detachably connected to the first pipe body; that is, the end of the first pipe body connected to the first pipe segment is located within the first compartment. Similarly, the third pipe segment is at least partially located within the second compartment and detachably connected to the second pipe body; that is, the end of the second pipe body connected to the third pipe segment is located within the second compartment. This design minimizes interference between the first and second pipe bodies and the transport equipment during separate transport of the first and second compartments, reducing transport difficulty and costs. The second pipe segment includes a deformable tube, which absorbs manufacturing and assembly errors, facilitating the connection of the first pipe segment to the first pipe body and the connection of the third pipe segment to the third pipe body.

[0028] As an optional technical solution in this application embodiment, the second pipe segment is a deformable pipe.

[0029] In the above technical solution, the second tube is a deformable tube as a whole, which allows the second tube to obtain a larger deformation, thereby facilitating the absorption of manufacturing and assembly errors.

[0030] As an optional technical solution in this application embodiment, the second pipe segment includes a connecting segment and a plurality of deformable pipes, wherein the connecting segment connects two adjacent deformable pipes.

[0031] In the above technical solution, the second pipe section includes multiple deformable tubes, each of which can deform, so that the second pipe body can obtain a larger deformation, thereby facilitating the absorption of manufacturing and assembly errors.

[0032] As an optional technical solution in this application embodiment, the plurality of deformable tubes include a first deformable tube and a second deformable tube, the connecting segment and the first tube segment are spaced apart along a first direction, the connecting segment and the third tube segment are spaced apart along a second direction, the first deformable tube connects the first tube segment and the connecting segment, the second deformable tube connects the third tube segment and the connecting segment, and the second direction is perpendicular to the first direction.

[0033] In the above technical solution, since the deformation of the deformable tube along its axial direction is relatively small, by setting a first deformable tube and a second deformable tube, the first deformable tube connects the first tube body and the connecting section that are spaced apart along the first direction, and the second deformable tube connects the third tube section and the connecting section that are spaced apart along the second direction. In this way, the first deformable tube has a large amount of deformation in the direction perpendicular to the first direction, and the second deformable tube has a large amount of deformation in the direction perpendicular to the second direction. Thus, the second tube section can obtain a large amount of deformation in all directions, which facilitates the absorption of manufacturing errors and assembly errors.

[0034] As an optional technical solution in this application embodiment, the plurality of deformable tubes include a first deformable tube and a second deformable tube. The first deformable tube is located in the first chamber, and the second deformable tube is located in the second chamber. The first tube segment and the connecting segment are spaced apart along a second direction. The first deformable tube connects the first tube segment and the connecting segment. The third tube segment and the connecting segment are spaced apart along the second direction. The second deformable tube connects the third tube segment and the connecting segment. The second direction is perpendicular to the first direction.

[0035] In the above technical solution, the first deformable tube connects the first pipe segment and the connecting segment that are spaced apart along the second direction, and the second deformable tube connects the third pipe segment and the connecting segment that are spaced apart along the second direction. In this way, the deformation of the second pipe segment is larger in the direction perpendicular to the second direction, which can better absorb the manufacturing error and assembly error in the direction perpendicular to the second direction.

[0036] As an optional technical solution in this application embodiment, the connecting pipe includes a plurality of second pipe segments, one end of each second pipe segment is connected to the first pipe segment, and the other end is connected to the third pipe segment, and each second pipe segment connects the first pipe segment and the third pipe segment.

[0037] In the above technical solution, by setting multiple second pipe sections, each second pipe section is connected to the first pipe section and the third pipe section, and is in communication with the first pipe section and the third pipe section. Each second pipe section can deform, so that the second pipe section can obtain a large amount of deformation in all directions, thereby facilitating the absorption of manufacturing errors and assembly errors.

[0038] As an optional technical solution in this application embodiment, the plurality of second pipe segments include a central pipe segment and a plurality of edge pipe segments located around the central pipe segment. The central pipe segment is located between the first pipe segment and the third pipe segment, and the plurality of edge pipe segments are arranged around the first pipe segment and the third pipe segment.

[0039] In the above technical solution, by setting a central pipe section and multiple edge pipe sections, the space around the first and third pipe sections is fully utilized, the flow cross-sectional area of ​​the second pipe section is increased, and the flow resistance of the first heat exchange medium in the second pipe section is reduced.

[0040] As an optional technical solution in this application embodiment, the second pipe segment and the first pipe segment are detachably connected, and / or the second pipe segment and the third pipe segment are detachably connected.

[0041] In the above technical solution, by detachably connecting the second pipe segment and the first pipe segment, during installation, the first pipe segment can be connected to the first pipe body first, and then the second pipe segment can be connected to the first pipe segment. Since the second pipe segment can deform, it is easier to absorb manufacturing and assembly errors, thus reducing assembly difficulty. Similarly, by detachably connecting the second pipe segment and the third pipe segment, during installation, the third pipe segment can be connected to the second pipe body first, and then the second pipe segment can be connected to the third pipe segment. Because the second pipe segment can deform, it is easier to absorb manufacturing and assembly errors, thus reducing assembly difficulty.

[0042] As an optional technical solution in this application embodiment, the second pipe segment is a flexible hose.

[0043] In the above technical solution, when the second pipe section is a flexible hose, the second pipe section can obtain a large amount of deformation in all directions, which facilitates the absorption of manufacturing errors and assembly errors.

[0044] As an optional technical solution in this application embodiment, the outer diameter of each second pipe segment is smaller than the outer diameter of the first pipe segment, and / or the outer diameter of each second pipe segment is smaller than the outer diameter of the third pipe segment.

[0045] In the above technical solution, when the outer diameter of the second pipe segment is smaller than that of the first pipe segment, the smaller outer diameter of the second pipe segment makes it more prone to deformation, thus facilitating the absorption of manufacturing and assembly errors. When the outer diameter of the second pipe segment is smaller than that of the third pipe segment, the smaller outer diameter of the second pipe segment makes it more prone to deformation, thus facilitating the absorption of manufacturing and assembly errors.

[0046] As an optional technical solution in this application embodiment, the first pipe segment is provided with a first connector, the third pipe segment is provided with a second connector, the second pipe segment is connected to the first connector and the second connector, and the length of the second pipe segment along its extension direction is greater than the distance between the first connector and the second connector.

[0047] In the above technical solution, by making the length of the second pipe segment along its extension direction greater than the distance between the first joint and the second joint, the second pipe segment is in a bent state when connected to the first joint and the second joint under normal circumstances. When the distance between the first pipe body and the second pipe body is greater than the design distance due to manufacturing errors and assembly errors, the second pipe segment can more effectively absorb the manufacturing errors and assembly errors.

[0048] As an optional technical solution in this application embodiment, the sum of the flow cross-sectional areas of the plurality of second pipe sections is greater than or equal to the flow cross-sectional area of ​​the first pipe section, and / or the sum of the flow cross-sectional areas of the plurality of second pipe sections is greater than or equal to the flow cross-sectional area of ​​the third pipe section.

[0049] In the above technical solution, by making the sum of the flow cross-sectional areas of the multiple second pipe sections greater than or equal to the flow cross-sectional area of ​​the first pipe section, it is beneficial to reduce the flow resistance of the first heat exchange medium in the second pipe section. By making the sum of the flow cross-sectional areas of the multiple second pipe sections greater than or equal to the flow cross-sectional area of ​​the third pipe section, it is beneficial to reduce the flow resistance of the first heat exchange medium in the second pipe section.

[0050] As an optional technical solution in this application embodiment, the first chamber has a first wall, the second chamber has a second wall, the first wall and the second wall are arranged opposite to each other along the first direction, and the second pipe segment passes through the first wall and the second wall.

[0051] In the above technical solution, the second pipe segment passes through the first wall and the second wall, while the first pipe segment is located inside the first compartment and detachably connected to the first pipe body. This facilitates the connection between the first pipe segment and the first pipe body and reduces the risk of interference between the first pipe segment and other components. The third pipe segment is located inside the second compartment and detachably connected to the second pipe body. This facilitates the connection between the third pipe segment and the second pipe body and reduces the risk of interference between the third pipe segment and other components.

[0052] As an optional technical solution in this application embodiment, the first pipe body includes a first flow-blocking device, the second pipe body includes a second flow-blocking device, and the connection position between the first pipe body and the second pipe body is located between the first flow-blocking device and the second flow-blocking device.

[0053] In the above technical solution, since the energy storage system needs to be debugged before leaving the factory, the first and second tubes already contain the first heat exchange medium. When it is necessary to disassemble the first and second tubes, the first and second flow-blocking devices can be closed first, so that most of the first heat exchange medium can be retained in the first and second tubes during disassembly. During assembly, the first tube is first connected to the second tube, and then the first and second flow-blocking devices are opened to connect the first and second tubes, thereby realizing the circulation of the first heat exchange medium.

[0054] As an optional technical solution in this application embodiment, the first compartment includes a first isolation layer, the first battery device and the thermal management module are respectively located on both sides of the first isolation layer, and along the first direction, the thermal management module is located on the side of the first isolation layer away from the second compartment.

[0055] In the above technical solution, the first isolation layer separates the thermal management module and the first battery device, which helps to reduce the risk of interference between the thermal management module and the first battery device, thereby improving the reliability of the energy storage system.

[0056] As an optional technical solution in this application embodiment, the pipeline system includes an inlet pipeline and a return pipeline. The inlet pipeline is used to supply the first heat exchange medium from the thermal management module to the first thermal management component and the second thermal management component. The return pipeline is used to supply the first heat exchange medium from the first thermal management component and the second thermal management component to the thermal management module. The inlet pipeline and / or the return pipeline both include the first pipe body and the second pipe body. The first isolation layer is provided with a first outlet hole through which the inlet pipeline and / or the return pipeline passes.

[0057] In the above technical solution, the liquid inlet pipe can pass through a second outlet hole and connect to the thermal management module, the first thermal management component, and the second thermal management component, so that the first heat exchange medium can flow from the thermal management module to the first thermal management component and the second thermal management component. The liquid return pipe can pass through another second outlet hole and connect to the thermal management module, the first thermal management component, and the second thermal management component, so that the first heat exchange medium can flow from the first thermal management component and the second thermal management component to the thermal management module, thereby realizing the circulation of the first heat exchange medium.

[0058] As an optional technical solution in this application embodiment, the liquid inlet pipeline and / or the liquid return pipeline includes a main pipe, a first main pipe and a second main pipe. One end of the main pipe is connected to the thermal management module, and the other end of the main pipe passes through the first outlet hole and is connected to the first main pipe and the second main pipe. The first main pipe is connected to the thermal management component of the first battery device, and the second main pipe is connected to the thermal management component of the second battery device. The second main pipe includes the first pipe body and the second pipe body.

[0059] In the above technical solution, one end of the main pipe is connected to the thermal management module, and the other end of the main pipe passes through the first lead hole and is connected to the first main pipe and the second main pipe. In this way, only the main pipe needs to pass through the first isolation layer, while the first main pipe and the second main pipe do not need to pass through the first isolation layer, which helps to reduce the number of holes.

[0060] As an optional technical solution in this application embodiment, the first compartment contains a plurality of first battery devices, which are arranged in rows and columns. The plurality of first battery devices in each row are arranged along the length of the first compartment, and the plurality of first battery devices in each column are arranged along the height. The inlet pipe and / or the return pipe further includes a plurality of first branches, each of which is connected to the thermal management component of the plurality of first battery devices in a column. The first main pipe connects the plurality of first branches and the main pipe. And / or the second compartment contains a plurality of second battery devices, which are arranged in rows and columns. The plurality of second battery devices in each row are arranged along the length of the second compartment, and the plurality of second battery devices in each column are arranged along the height. The inlet pipe and / or the return pipe further includes a plurality of second branches, each of which is connected to the thermal management component of the plurality of second battery devices in a column. The second main pipe connects the plurality of second branches and the main pipe.

[0061] In the above technical solution, a first main pipe connects to multiple first branches and a main pipe. Each first branch is connected to the thermal management components of multiple first battery devices in a row. The thermal management module can provide a first heat exchange medium to the main pipe. The first heat exchange medium is then supplied to the thermal management components of the multiple first battery devices via the main pipe, the first main pipe, and the multiple first branches, resulting in a more uniform temperature of the first heat exchange medium entering the thermal management components of the multiple first battery devices and reducing the risk of battery cell temperature runaway. Similarly, a second main pipe connects to multiple second branches and a main pipe. Each second branch is connected to the thermal management components of multiple second battery devices in a row. The thermal management module can provide a first heat exchange medium to the main pipe. The first heat exchange medium is then supplied to the thermal management components of the multiple second battery devices via the main pipe, the second main pipe, and the multiple second branches, resulting in a more uniform temperature of the first heat exchange medium entering the thermal management components of the multiple second battery devices and reducing the risk of battery cell temperature runaway.

[0062] As an optional technical solution in this application embodiment, the thermal management module further includes a pumping device, a first heat exchanger, a second heat exchanger, a compressor, and a throttling device. The pumping device, the first heat exchanger, and the first thermal management component are connected through the pipeline system to form a first heat exchange circulation loop. The pumping device, the first heat exchanger, and the second thermal management component are connected through the pipeline system to form a second heat exchange circulation loop. The second heat exchange circulation loop includes a first pipe body and a second pipe body. The compressor, the second heat exchanger, the throttling device, and the heat exchanger are connected to form a third heat exchange circulation loop. The third heat exchange circulation loop is used for heat exchange with the first heat exchange circulation loop and the second heat exchange circulation loop.

[0063] In the above technical solution, the first heat exchange circulation loop can perform thermal management on the first battery device, the second heat exchange circulation loop can perform thermal management on the second battery device, and the third heat exchange circulation loop can perform heat exchange on the first heat exchange medium passing through the first heat exchanger, so that the first heat exchange medium has a better heat exchange effect on the first battery device and the second battery device.

[0064] As an optional technical solution in this application embodiment, the first direction is the height direction, and the first compartment is located above the second compartment.

[0065] In the above technical solution, by setting up a first compartment and a second compartment, the first battery device is housed in the first compartment and the second battery device is housed in the second compartment. The first compartment and the second compartment are stacked along the height direction, which can reduce the footprint of the energy storage system, thereby increasing the energy per unit area of ​​the energy storage system and improving the area energy density of the energy storage system.

[0066] As an optional technical solution in this application embodiment, the thermal management module is located inside the first compartment and on top of the first battery device.

[0067] In the above technical solution, by housing the thermal management module within the first compartment, the thermal management module can share a portion of the floor space with the first compartment. Given a fixed total energy of the energy storage system, the system can have a smaller volume, resulting in a smaller footprint and thus increasing the energy density per unit area. Furthermore, placing the thermal management module on top of the first battery device offers several advantages. First, fewer obstructions above the module improve its heat dissipation, enhancing its efficiency and reducing auxiliary power consumption. Second, it reduces the impact of solar radiation on the temperature of the first battery device, improving temperature consistency between the first and second battery devices.

[0068] As an optional technical solution in this application embodiment, the first direction is the height direction, the dimensions of the first and second storage bodies along their length direction are consistent with the dimensions of the standard container along its length direction, the dimensions of the first and second storage bodies along their width direction are consistent with the dimensions of the standard container along its width direction, and the dimensions of the first and second storage bodies along their height direction are smaller than the dimensions of the standard container along its height direction.

[0069] In the above technical solution, by ensuring that the dimensions of both the first and second compartments along their length and width are identical to those of a standard shipping container, it is beneficial to match existing standard container transport vehicles and lifting gear, reducing the transportation cost of the energy storage system and thus lowering its operating cost. When the dimensions of both the first and second compartments along their height are smaller than those of a standard shipping container, the total weight of the first compartment and its components, as well as the total weight of the second compartment and its components, can be reduced. This helps to address the issue of overweight transport and further lowers the transportation cost of the energy storage system.

[0070] As an optional technical solution in this application embodiment, the total weight of the first silo and the components disposed in the first silo is less than or equal to 36 tons; and / or the total weight of the second silo and the components disposed in the second silo is less than or equal to 36 tons.

[0071] In the above technical solution, by making the total weight of the first compartment and the components installed in the first compartment less than or equal to 36 tons, and the total weight of the second compartment and the components installed in the second compartment less than or equal to 36 tons, the transportation limits of some countries are met, and the transportation difficulty and transportation cost are reduced.

[0072] As an optional technical solution in this application embodiment, the energy storage system further includes a control module, a first battery monitoring circuit, and a second battery monitoring circuit. The first battery monitoring circuit is used to collect first data of the first battery device, and the second battery monitoring circuit is used to collect second data of the second battery device. The control module is used to determine the operating status data of the energy storage system, and the operating status data of the energy storage system is associated with the first data and the second data.

[0073] In the above technical solution, the working status data of the energy storage system determined by the control module is associated with the first data of the first battery device collected by the first battery monitoring circuit and the second data of the second battery device collected by the second battery monitoring circuit. This enables the control module to control the first battery device and the second battery device, which helps to reduce the number of control modules required, maximizes the utilization of the control modules, and helps to reduce the cost of the energy storage system.

[0074] As an optional technical solution in this application embodiment, the energy storage system further includes a first sub-control module and a second sub-control module. The first sub-control module is communicatively connected between the first battery monitoring circuit and the control module, and the second sub-control module is communicatively connected between the second battery monitoring circuit and the control module. The first sub-control module is used to forward the first data, and the second sub-control module is used to forward the second data; or, the first sub-control module is used to acquire and process the first data and transmit the processed data to the control module, and the second sub-control module is used to acquire and process the second data and transmit the processed data to the control module.

[0075] In the above technical solution, by setting a first sub-control module between the first battery monitoring circuit and the control module, and setting a second sub-control module between the second battery monitoring circuit and the control module, the control system of the energy storage system is made into a three-level framework. This reduces the length and complexity of the communication harness, reduces sampling errors, improves the reliability of the control system, and also reduces the requirements for the processor and communication bus, thus reducing the overall cost of the control system.

[0076] As an optional technical solution in this application embodiment, the control module is housed in the first compartment or the second compartment.

[0077] In the above technical solution, there is only one control module, which can be housed in the first compartment or the second compartment. The first compartment or the second compartment can protect the control module and reduce the risk of damage to the control module.

[0078] Secondly, this application embodiment also provides a method for disassembling an energy storage system, which is used to disassemble the above-mentioned energy storage system. The method for disassembling the energy storage system includes: a disconnection step: separating the first tube and the second tube; and a separation step: separating the first compartment and the second compartment.

[0079] As an optional technical solution in this application embodiment, the pipeline system further includes a connecting pipe, and the first pipe body and the second pipe body are detachably connected through the connecting pipe; the disconnection step includes: separating the connecting pipe from the first pipe body and separating the connecting pipe from the second pipe body.

[0080] In the above technical solution, by setting a connecting pipe, one end of the connecting pipe is detachably connected to the first pipe body, and the other end of the connecting pipe is detachably connected to the second pipe body, which helps to reduce the difficulty of separating the first pipe body and the second pipe body.

[0081] As an optional technical solution in this application embodiment, the first pipe body includes a first flow-blocking device, and the second pipe body includes a second flow-blocking device; before the disconnection step, the disassembly method of the energy storage system further includes a shut-off step: shutting off the first flow-blocking device and the second flow-blocking device.

[0082] In the above technical solution, since the energy storage system needs to be debugged before leaving the factory, the first tube, connecting pipe, and second tube already contain the first heat exchange medium. When it is necessary to disassemble the connecting pipe, the first and second throttling devices can be closed first, thereby cutting off the first tube and connecting pipe, and cutting off the second tube and connecting pipe. In this way, the first heat exchange medium in the first and second tubes is less likely to leak during disassembly. During assembly, the connecting pipe is first connected to the first and second tubes, and then the first and second throttling devices are opened, so that the first tube and connecting pipe are connected, and the second tube and connecting pipe are connected, so as to realize the circulation of the first heat exchange medium.

[0083] As an optional technical solution in this application embodiment, after the shutdown step and before the disconnection step, the disassembly method of the energy storage system further includes: a draining step: draining the first heat exchange medium in the connecting pipe.

[0084] In the above technical solution, the connecting pipe already contains the first heat exchange medium before disassembling the connecting pipe. By first discharging the first heat exchange medium in the connecting pipe and then disassembling the connecting pipe, the difficulty of disassembling the connecting pipe can be reduced.

[0085] As an optional technical solution in this application embodiment, the connecting pipe is provided with a vent and a discharge port, the vent is positioned higher than the discharge port, the vent is provided with a first switch, and the discharge port is provided with a second switch; the draining step includes: opening the vent through the first switch and opening the discharge port through the second switch to discharge the first heat exchange medium in the connecting pipe from the discharge port.

[0086] In the above technical solution, the vent is opened by the first switch to balance the air pressure inside and outside the connecting pipe, and then the exhaust port is opened by the second switch to release the first heat exchange medium in the connecting pipe. This allows for a simple and convenient way to discharge the first heat exchange medium in the connecting pipe.

[0087] Thirdly, this application embodiment also provides an installation method for an energy storage system, used to install the above-mentioned energy storage system. The installation method for the energy storage system includes: a layout step: arranging the first chamber and the second chamber along the first direction; and a connection step: connecting the first pipe and the second pipe.

[0088] As an optional technical solution in this application embodiment, the energy storage system further includes a connecting pipe; the connection step includes: connecting the first pipe body and the second pipe body through the connecting pipe.

[0089] In the above technical solution, by setting a connecting pipe, one end of the connecting pipe is used to be detachably connected to the first pipe body, and the other end of the connecting pipe is used to be detachably connected to the second pipe body, which helps to reduce the difficulty of installing the first pipe body and the second pipe body.

[0090] As an optional technical solution in this application embodiment, the first pipe body includes a first flow-blocking device, and the second pipe body includes a second flow-blocking device; after the connection step, the installation method of the energy storage system further includes an opening step: opening the first flow-blocking device and the second flow-blocking device.

[0091] In the above technical solution, after the connecting pipe is connected to the first pipe body and the second pipe body, the first and second flow-blocking devices can be opened to connect the first pipe body and the connecting pipe, and the second pipe body and the connecting pipe to facilitate the circulation of the first heat exchange medium.

[0124] The battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar.

[0125] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0126] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0127] In some embodiments, the battery device may include one or more battery packs, and the battery packs may include one or more battery cell assemblies. As an example, the battery pack includes a housing and one or more battery cell assemblies, the battery cell assemblies being housed within the housing, for example, by a fixed manner. As yet another example, the battery device includes multiple battery packs, which may be connected in series, parallel, or in a mixed configuration.

[0128] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0129] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0130] In some embodiments, the battery device includes multiple battery packs that can constitute one or more battery clusters, thereby providing an energy storage system that includes one or more battery clusters to improve the voltage and capacity of the energy storage system. A battery cluster may include multiple battery packs, which are connected in series via a busbar to increase the voltage of the energy storage system. When the energy storage system includes multiple battery clusters, these clusters can be connected in series, in parallel, or in a hybrid configuration.

[0131] Energy storage systems can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. An energy storage system can store electrical energy as needed and output it when appropriate. For example, an energy storage system can store electrical energy during off-peak hours and provide power to relevant users or electrical equipment during peak hours. The energy storage system provided in this application embodiment can be any power system that requires energy storage.

[0132] In some embodiments, the energy storage system is an energy storage container or an energy storage cabinet.

[0133] In some embodiments, the energy storage system may include a housing and one or more battery clusters, with the battery clusters housed within the housing.

[0134] In some embodiments, the energy storage system may include modules such as a thermal management module, a sub-control module, a control module, a power distribution module, and a fire protection module.

[0135] As an example, the thermal management module may include a liquid cooling unit that provides a first heat exchange medium for regulating the temperature of individual battery cells to each battery device via piping.

[0136] As an example, the sub-control module can serve as the battery management unit for the battery cluster, used to monitor and manage the battery cluster. The sub-control module can monitor information such as the current, voltage, power, or temperature of the battery cluster. For example, it can control the charging and discharging current and voltage of the battery cluster. The sub-control module includes modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0137] As an example, the control module can serve as the battery management unit of an energy storage system, used to monitor and manage the system. The control module can monitor information such as current, voltage, power, state of charge, and temperature of the energy storage system. For instance, it can control the charging and discharging current and voltage of the energy storage system. As an example, the master control module includes modules such as the Insulation Monitoring Module (IMM), the Master Battery Management Unit (MBMU), the Ethernet (ETH) module, and the fiber optic conversion module.

[0138] As an example, a fire protection system includes control panels, detectors, alarm devices, etc., used to detect, alarm, or extinguish fires in energy storage systems.

[0139] As an example, the power distribution unit can be used to distribute power to the power modules of an energy storage system.

[0140] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in energy storage systems such as energy storage containers or energy storage cabinets.

[0141] Power plants are demanding increasingly higher capacity and energy density from energy storage systems, leading to ever-larger systems. However, the excessive size of these systems makes transportation difficult, creating a conflict between increasing capacity and energy density and efficient transport.

[0142] In view of this, embodiments of this application provide an energy storage system, which includes a first compartment, a first battery device, a second compartment, a second battery device, a thermal management module, and a piping system. The first compartment houses the first battery device, which includes a first thermal management component. The second compartment houses the second battery device, and the first and second compartments are arranged along a first direction. The second battery device includes a second thermal management component. The piping system connects the thermal management module, the first thermal management component, and the second thermal management component. The thermal management module manages the temperature of the first and second battery devices. The piping system includes a first pipe and a second pipe. The first pipe is connected to the thermal management module and is at least partially housed within the first compartment, and the second pipe is connected to the second thermal management component and is at least partially housed within the second compartment. The first and second pipes are detachably connected.

[0143] By configuring a first compartment and a second compartment, the first battery device is housed in the first compartment, and the second battery device in the second compartment, which helps to improve the capacity and energy density of the energy storage system. This energy storage system uses a single thermal management module to manage the thermal of both the first and second battery devices, which helps reduce the number of thermal management modules, lowers the production cost of the energy storage system, reduces the space occupied by the system, and improves the volumetric energy density. A first tube is connected to the thermal management module, and a second tube is connected to a second thermal management component. The first and second tubes are detachably connected. This allows the first heat exchange medium to flow from the thermal management module to the second thermal management component or vice versa, thus managing the thermal of the second battery device. Furthermore, the detachable connection allows the first and second tubes to be separated during transportation, facilitating the separate transport of the first and second compartments, reducing transportation difficulty and costs. In addition, by making the first pipe body and the second pipe body detachably connected, the air tightness of the first pipe body and the second pipe body can be tested separately when testing air tightness, which can reduce the time for tracing leaks and quickly determine the leak point.

[0144] The energy storage system described in this application embodiment may include an energy storage container or an energy storage cabinet. The energy storage system may include a power converter system (PCS) for connecting between a power generation device and a battery device. The power generation device generates electrical energy, which can be stored in the battery device through the power converter. As an example, the power generation device may specifically be a solar panel, hydroelectric power generation equipment, thermal power generation equipment, wind power generation equipment, etc.

[0145] Please refer to Figures 1, 2, and 3. Figure 1 is a structural schematic diagram of an energy storage system 10 provided in some embodiments of this application. Figure 2 is a structural schematic diagram of the internal structure of the energy storage system 10 provided in some embodiments of this application. Figure 3 is a structural schematic diagram of a piping system 600 provided in some embodiments of this application. This application provides an energy storage system 10, which includes a first compartment 100, a first battery device 300, a second compartment 200, a second battery device 400, a thermal management module 500, and a piping system 600. The first compartment 100 houses the first battery device 300, which includes a first thermal management component 310. The second compartment 200 houses the second battery device 400, and the first compartment 100 and the second compartment 200 are arranged along a first direction. The second battery device 400 includes a second thermal management component 410. The piping system 600 connects the thermal management module 500, the first thermal management component 310, and the second thermal management component 410. The thermal management module 500 manages the temperature of the first battery device 300 and the second battery device 400. The piping system 600 includes a first pipe body 6131 and a second pipe body 6132. The first pipe body 6131 is connected to the thermal management module 500 and is at least partially housed within the first compartment 100. The second pipe body 6132 is connected to the second thermal management component 410 and is at least partially housed within the second compartment 200. The first pipe body 6131 and the second pipe body 6132 are detachably connected.

[0146] The first direction can be the height direction of the first compartment 100, the length direction of the first compartment 100, or the width direction of the first compartment 100. Referring to Figures 1 and 2, the first direction is the X direction shown in the figures. In the embodiment shown in the figures, the first direction is the height direction, that is, the first compartment 100 and the second compartment 200 are stacked along the height direction. Along the height direction, the first compartment 100 is stacked on top of the second compartment 200, and the second compartment 200 can support the first compartment 100, thereby helping to reduce the footprint of the energy storage system 10 and increase the area energy density of the energy storage system 10.

[0147] In other embodiments, the second compartment 200 and the first compartment 100 may also be stacked along the length or width of the first compartment 100.

[0148] The first compartment 100 and the second compartment 200 are two different compartment structures in the energy storage system 10. Both can form a hollow structure, which serves as a space to house and protect the devices in the energy storage system 10.

[0149] The first compartment 100 and the second compartment 200 are two different compartment structures in the energy storage system 10. Both can form a hollow structure, which serves as a space to house and protect the devices in the energy storage system 10. The first compartment 100 houses the first battery device 300, meaning that the first battery device 300 is located in the hollow structure formed by the first compartment 100. The first battery device 300 located in the hollow structure of the first compartment 100 can be connected to the wall of the first compartment 100 using bolts, rivets, connecting pins, or other connecting components. Alternatively, it can be first fixed to a shelf, and then the shelf can be connected to the wall of the first compartment 100 using bolts, rivets, connecting pins, or other connecting components. This reduces the possibility of the first battery device 300 moving due to shaking within the housing space of the first compartment 100, thus reducing the possibility of damage to the first battery device 300.

[0150] For example, the first battery device 300 may be a part of the battery devices in the energy storage system 10, which also includes other battery devices besides the first battery device 300. The first compartment 100 and other compartments are used together to house the battery devices in the energy storage system 10, with the first battery device 300 housed in the first compartment 100 and the other battery devices housed in the other compartments.

[0151] The second compartment 200 houses the second battery device 400. This means that the second battery device 400 is located in the hollow structure formed by the second compartment 200. The second battery device 400 located in the hollow structure of the second compartment 200 can be connected to the wall of the second compartment 200 using bolts, rivets, connecting pins, or other connecting components. Alternatively, it can be first fixed to a shelf, and then the shelf can be connected to the wall of the second compartment 200 using bolts, rivets, connecting pins, or other connecting components. This reduces the possibility of the second battery device 400 moving due to shaking in the housing space of the second compartment 200, and helps to reduce the possibility of damage to the second battery device 400.

[0152] The thermal management module 500 is a component used for thermal management of the first battery device 300 and the second battery device 400. For example, when the temperature of the first battery device 300 and the second battery device 400 rises, the thermal management module 500 can cool the first battery device 300 and the second battery device 400, thereby lowering their temperatures. When the temperature of the first battery device 300 and the second battery device 400 decreases, the thermal management module 500 can heat the first battery device 300 and the second battery device 400, thereby raising their temperatures. In other words, the thermal management module 500 can maintain the temperatures of the first battery device 300 and the second battery device 400 within a certain range, allowing them to operate at a more suitable temperature, thus maximizing their performance.

[0153] The thermal management module 500 can be a liquid chiller, an air conditioner, a ground source cooling device, or a marine liquid cooling device.

[0154] The first battery device 300 includes a first thermal management component 310 and a battery cell 320, wherein the first thermal management component 310 is used to manage the temperature of the battery cell 320.

[0155] The first thermal management component 310 can be plate-shaped or tubular, etc. The first thermal management component 310 has a flow channel inside, which can be used to introduce the first heat exchange medium to heat or cool the battery cell 320.

[0156] When the first battery device 300 is a battery module, the first thermal management component 310 can be the bottom plate, top plate or side plate of the battery module, or it can be located between adjacent battery cells 320.

[0157] When the first battery device 300 is a battery pack, the first thermal management component 310 can be part of the housing or located within the housing's containment space. The first thermal management component 310 can also be located between adjacent battery cells 320.

[0158] Optionally, the first thermal management component 310 is a water-cooled plate. In this case, the first heat exchange medium can be water, other fluids, or a mixture of water and other fluids.

[0159] The second battery device 400 includes a second thermal management component 410 and a battery cell 320, wherein the second thermal management component 410 is used to manage the temperature of the battery cell 320.

[0160] The second thermal management component 410 can be plate-shaped or tubular, etc. The second thermal management component 410 has a flow channel inside, which can be used to introduce the first heat exchange medium to heat or cool the battery cell 320.

[0161] When the second battery device 400 is a battery module, the second thermal management component 410 can be the bottom plate, top plate or side plate of the battery module, or it can be located between adjacent battery cells 320.

[0162] When the second battery device 400 is a battery pack, the second thermal management component 410 can be part of the housing or located within the housing's containment space. The second thermal management component 410 can also be located between adjacent battery cells 320.

[0163] Optionally, the second thermal management component 410 is a water-cooled plate. In this case, the first heat exchange medium can be water, other fluids, or a mixture of water and other fluids.

[0164] The piping system 600 connects the thermal management module 500, the first thermal management component 310, and the second thermal management component 410 to enable the first heat exchange medium to circulate between the thermal management module 500 and the first thermal management component 310, and between the thermal management module 500 and the second thermal management component 410.

[0165] The first tube 6131 can be partially housed inside the first compartment 100 and partially housed outside the first compartment 100, or it can be completely housed inside the first compartment 100. One end of the first tube 6131 is connected to the thermal management module 500, and the other end of the first tube 6131 is used to connect to the second tube 6132.

[0166] The second tube 6132 can be partially housed inside the second compartment 200 and partially housed outside the second compartment 200, or it can be completely housed inside the second compartment 200. One end of the second tube 6132 is connected to the second thermal management component 410, and the other end of the second tube 6132 is used to connect to the first tube 6131.

[0167] "Detachable connection" refers to a connection method in which the connecting parts and the connected parts remain undamaged and maintain the original connection quality even after repeated assembly and disassembly.

[0168] In some embodiments, the first pipe body 6131 and the second pipe body 6132 can be mated together and locked by a clamp to achieve a detachable connection. A clamp can refer to a mechanical fitting used for fastening, connecting, or sealing pipes, hoses, and other cylindrical components, typically made of metal or plastic. The clamp secures the first pipe body 6131 and the second pipe body 6132 together through clamping force.

[0169] To improve the sealing performance of the first tube 6131 and the second tube 6132, sealing elements can be installed on the outer side of the mating position of the first tube 6131 and the second tube 6132 and on the inner side of the clamp.

[0170] In other embodiments, the first tube 6131 and the second tube 6132 can be inserted into each other to achieve a detachable connection. To improve the tightness of the connection between the first tube 6131 and the second tube 6132, they can be locked with clamps after being inserted into each other.

[0171] By setting up a first compartment 100 and a second compartment 200, the first battery device 300 is housed in the first compartment 100, and the second battery device 400 is housed in the second compartment 200, which helps to improve the capacity and energy density of the energy storage system 10. The energy storage system 10 uses a thermal management module 500 to manage the thermal of the first battery device 300 and the second battery device 400, which helps to reduce the number of thermal management modules 500, lower the production cost of the energy storage system 10, reduce the space occupied by the energy storage system 10, and improve the volumetric energy density of the energy storage system 10. A first tube 6131 is connected to the thermal management module 500, and a second tube 6132 is connected to the second thermal management component 410. The first tube 6131 and the second tube 6132 are detachably connected, allowing the first heat exchange medium to flow from the thermal management module 500 to the second thermal management component 410 or vice versa, thereby achieving thermal management of the second battery device 400. On the other hand, the first pipe body 6131 and the second pipe body 6132 are detachably connected. During transportation, the first pipe body 6131 and the second pipe body 6132 can be separated, which facilitates the separate transportation of the first compartment 100 and the second compartment 200, reducing transportation difficulty and costs. Furthermore, by making the first pipe body 6131 and the second pipe body 6132 detachably connected, the airtightness of the first pipe body 6131 and the second pipe body 6132 can be tested separately during airtightness testing, reducing the time required to locate leaks and quickly identifying the leak point.

[0172] Please refer to Figures 1, 2, 3, 4, 5, 6, 7, and 8. Figure 4 is a schematic diagram showing the connection between the first pipe body 6131, the connecting pipe 6133, and the second pipe body 6132 according to some embodiments of this application. Figure 5 is a cross-sectional view of the first pipe body 6131, the connecting pipe 6133, and the second pipe body 6132 according to some embodiments of this application. Figure 6 is an enlarged view showing the connection between the first pipe body 6131 and the connecting pipe 6133 according to some embodiments of this application. Figure 7 is an enlarged view showing the connection between the second pipe body 6132 and the connecting pipe 6133 according to some embodiments of this application. Figure 8 is a schematic diagram showing the connection between the first pipe body 6131, the connecting pipe 6133, and the second pipe body 6132 according to other embodiments of this application. In some embodiments, the piping system 600 further includes a connecting pipe 6133, and the first pipe body 6131 and the second pipe body 6132 are detachably connected through the connecting pipe 6133.

[0173] The connecting pipe 6133 is a pipe structure used to connect the first pipe body 6131 and the second pipe body 6132. One end of the connecting pipe 6133 is detachably connected to the first pipe body 6131, and the other end of the connecting pipe 6133 is detachably connected to the second pipe body 6132.

[0174] The connecting pipe 6133 can be bolted to the first pipe body 6131, or it can be inserted into the first pipe body 6131. ​​The connecting pipe 6133 can be bolted to the second pipe body 6132, or it can be inserted into the second pipe body 6132.

[0175] By providing a connecting pipe 6133, one end of which is detachably connected to the first pipe body 6131 and the other end of which is detachably connected to the second pipe body 6132, the difficulty of separating the first pipe body 6131 and the second pipe body 6132 is reduced. Furthermore, by making the first pipe body 6131 and the second pipe body 6132 detachably connected via the connecting pipe 6133, the airtightness of the first pipe body 6131, the second pipe body 6132, and the connecting pipe 6133 can be tested separately during airtightness testing, reducing the time required to locate leaks and allowing for rapid identification of the leak point.

[0176] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the connecting pipe 6133 and the first pipe body 6131 are connected by a clamp 63. And / or the connecting pipe 6133 and the second pipe body 6132 are connected by a clamp 63.

[0177] In some embodiments, one end of the connecting pipe 6133 is mated with the first pipe body 6131 and locked by a clamp to achieve a detachable connection between the connecting pipe 6133 and the first pipe body 6131. ​​The other end of the connecting pipe 6133 is mated with the second pipe body 6132 and locked by a clamp to achieve a detachable connection between the connecting pipe 6133 and the second pipe body 6132. A clamp can refer to a mechanical fitting used for fastening, connecting, or sealing pipes, hoses, and other cylindrical components, typically made of metal or plastic. The clamp secures the first pipe body 6131 and the second pipe body 6132 together through clamping force.

[0178] In other embodiments, one end of the connecting pipe 6133 is inserted into the first pipe body 6131, and after the connecting pipe 6133 and the first pipe body 6131 are inserted into each other, they are locked with a clamp to improve the tightness of the connection between the connecting pipe 6133 and the first pipe body 6131. ​​The other end of the connecting pipe 6133 is inserted into the second pipe body 6132, and after the connecting pipe 6133 and the second pipe body 6132 are inserted into each other, they are locked with a clamp to improve the tightness of the connection between the connecting pipe 6133 and the second pipe body 6132.

[0179] The connecting pipe 6133 and the first pipe body 6131 are connected by clamps, which is simple and convenient, easy to assemble and disassemble, and has high reliability. The connecting pipe 6133 and the second pipe body 6132 are connected by clamps, which is also simple and convenient, easy to assemble and disassemble, and has high reliability.

[0180] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the energy storage system 10 includes a first seal 6134, which seals the connecting pipe 6133 and the first pipe body 6131. ​​And / or the energy storage system 10 includes a second seal 6135, which seals the connecting pipe 6133 and the second pipe body 6132.

[0181] The first sealing element 6134 is used to seal the gap between the connecting pipe 6133 and the first pipe body 6131. ​​The first sealing element 6134 is a structure capable of achieving a sealing effect, such as sealant, gasket, or sealing sheet.

[0182] In an embodiment where one end of the connecting pipe 6133 is mated with the first pipe body 6131 and locked by a clamp, a first sealing element 6134 can be provided on the outside of the mating position of the connecting pipe 6133 and the first pipe body 6131 and on the inside of the clamp.

[0183] The second seal 6135 is used to seal the gap between the connecting pipe 6133 and the second pipe body 6132. The second seal 6135 is a structure that can achieve a sealing effect, such as sealant, gasket, or sealing sheet.

[0184] In an embodiment where one end of the connecting pipe 6133 is mated with the second pipe body 6132 and locked by a clamp, in order to improve the sealing performance between the connecting pipe 6133 and the second pipe body 6132, a sealing element can be provided on the outside of the mating position of the connecting pipe 6133 and the second pipe body 6132 and on the inside of the clamp.

[0185] By providing a first seal 6134 to seal the gap between the connecting pipe 6133 and the first pipe body 6131, the risk of leakage of the first heat exchange medium from the connection point between the connecting pipe 6133 and the first pipe body 6131 is reduced. Similarly, by providing a second seal 6135 to seal the gap between the connecting pipe 6133 and the second pipe body 6132, the risk of leakage of the first heat exchange medium from the connection point between the connecting pipe 6133 and the second pipe body 6132 is also reduced.

[0186] In other embodiments, the connecting tube 6133 and the first tube body 6131 are quick-connected. And / or the connecting tube 6133 and the second tube body 6132 are quick-connected.

[0187] One of the connecting pipe 6133 and the first pipe body 6131 is provided with a quick-connect male connector, and the other is provided with a quick-connect female connector. The quick-connect male connector and the quick-connect female connector are connected by quick-connection, thereby realizing the quick-connection of the connecting pipe 6133 and the first pipe body 6131.

[0188] One of the connecting pipe 6133 and the second pipe body 6132 is provided with a quick-connect male connector, and the other is provided with a quick-connect female connector. The quick-connect male connector and the quick-connect female connector are connected by quick-connection, thereby realizing the quick-connection of the connecting pipe 6133 and the second pipe body 6132.

[0189] The quick-connect design of the connecting tube 6133 and the first tube body 6131 allows for easy assembly and disassembly without tools, thus improving efficiency. Similarly, the quick-connect design of the connecting tube 6133 and the second tube body 6132 also allows for easy assembly and disassembly without tools, further enhancing efficiency.

[0190] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the first pipe body 6131 includes a first flow-blocking device 710, which is configured to connect or disconnect the first pipe body 6131 and the connecting pipe 6133. The second pipe body 6132 includes a second flow-blocking device 720, which is configured to connect or disconnect the second pipe body 6132 and the connecting pipe 6133.

[0191] The first shut-off device 710 is a valve body structure used to control the connection or disconnection of the first pipe body 6131 and the connecting pipe 6133. When the first shut-off device 710 is open, the first pipe body 6131 and the connecting pipe 6133 are connected. When the first shut-off device 710 is closed, the first pipe body 6131 and the connecting pipe 6133 are disconnected. The second shut-off device 720 is a valve body structure used to control the connection or disconnection of the second pipe body 6132 and the connecting pipe 6133. When the second shut-off device 720 is open, the second pipe body 6132 and the connecting pipe 6133 are connected. When the second shut-off device 720 is closed, the second pipe body 6132 and the connecting pipe 6133 are disconnected.

[0192] Since the energy storage system 10 requires commissioning before leaving the factory, the first tube 6131, connecting tube 6133, and second tube 6132 already contain the first heat exchange medium. When it is necessary to disassemble the connecting tube 6133, the first shut-off device 710 and the second shut-off device 720 can be closed first, thereby cutting off the connection between the first tube 6131 and the connecting tube 6133, and the second tube 6132 and the connecting tube 6133. In this way, the first heat exchange medium in the first tube 6131 and the second tube 6132 is less likely to leak when disassembling the connecting tube 6133. During assembly, the connecting tube 6133 is first connected to the first tube 6131 and the second tube 6132, and then the first shut-off device 710 and the second shut-off device 720 are opened, so that the first tube 6131 and the connecting tube 6133 are connected, and the second tube 6132 and the connecting tube 6133 are connected, so as to realize the circulation of the first heat exchange medium.

[0193] In some embodiments, the first shut-off device 710 includes a valve or a self-sealing connector. And / or the second shut-off device 720 includes a valve or a self-sealing connector.

[0194] The valve can be a butterfly valve, ball valve, electric valve, etc. That is, the first shut-off device 710 can include a butterfly valve, ball valve, electric valve, self-sealing joint, etc., and the second shut-off device 720 can be a butterfly valve, ball valve, electric valve, self-sealing joint, etc.

[0195] When the first shut-off device 710 includes a valve, the first pipe body 6131 and the connecting pipe 6133 can be connected or disconnected by opening or closing the first shut-off device 710, and it can withstand greater pressure. When the first shut-off device 710 includes a self-sealing joint, the first pipe body 6131 and the connecting pipe 6133 can be automatically connected during installation and automatically disconnected during disassembly. When the second shut-off device 720 includes a valve, the second pipe body 6132 and the connecting pipe 6133 can be connected or disconnected by opening or closing the second shut-off device 720, and it can withstand greater pressure. When the second shut-off device 720 includes a self-sealing joint, it can automatically connect the second pipe body 6132 and the connecting pipe 6133 when installing the second pipe body 6132 and the connecting pipe 6133, and automatically disconnect the second pipe body 6132 and the connecting pipe 6133 when disassembling the second pipe body 6132 and the connecting pipe 6133.

[0196] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the connecting pipe 6133 is provided with a vent 730 and a discharge port 740, with the vent 730 positioned higher than the discharge port 740. The vent 730 is provided with a first switch 750, configured to open or close the vent 730. The discharge port 740 is provided with a second switch 760, configured to open or close the discharge port 740.

[0197] The vent 730 is an opening used to balance the air pressure inside and outside the connecting pipe 6133. The vent 730 is located in the connecting pipe 6133, and understandably, the vent 730 is located between the first switching valve 734 and the second switching valve 735.

[0198] The discharge port 740 is an opening for releasing the first heat exchange medium within the connecting pipe 6133. The discharge port 740 is located within the connecting pipe 6133, and understandably, it is situated between the first switching valve 734 and the second switching valve 735.

[0199] The vent 730 is positioned higher than the exhaust port 740 so that outside air can more easily enter the connecting pipe 6133, thereby balancing the internal and external air pressure of the connecting pipe 6133 more quickly.

[0200] A first switch element 750 is disposed at the vent 730, and is used to open or close the vent 730. When the first switch element 750 is open, the vent is opened, and the connecting pipe 6133 is connected to the outside, allowing outside air to enter the connecting pipe 6133, thereby balancing the air pressure inside and outside the connecting pipe 6133. For example, the first switch element 750 can be a vent cap, and the first switch element 750 is welded to the connecting pipe 6133.

[0201] A second switching element 760 is disposed at the discharge port 740, and the second switching element 760 is used to open or close the discharge port 740. When the first switching element 750 is open, the discharge port 740 is open, allowing the first heat exchange medium in the connecting pipe 6133 to be discharged through the discharge port 740. Optionally, the second switching element 760 is welded to the connecting pipe 6133.

[0202] In some embodiments, the second switching element 760 can be a drain fixture with a drain channel. When the drain fixture is in the open state, the drain channel is connected to the discharge port 740, allowing the first heat exchange medium in the connecting pipe 6133 to enter the drain channel through the discharge port 740 and be discharged from the drain channel. When the drain fixture is in the closed state, the drain channel is disconnected from the discharge port 740, preventing the first heat exchange medium in the connecting pipe 6133 from entering the drain channel through the discharge port 740. Optionally, the energy storage system 10 also includes a drain pipe detachably connected to the drain fixture. When the drain pipe is connected to the drain fixture, the internal space of the drain pipe is connected to the drain channel, allowing the first heat exchange medium in the connecting pipe 6133 to flow from the drain fixture to the drain pipe and finally be discharged through the drain pipe.

[0203] In other embodiments, the second switching element 760 can be a valve, such as a butterfly valve, ball valve, or electric valve.

[0204] In some other embodiments, the second switch 760 may be a self-sealing connector.

[0205] Before disassembling the connecting pipe 6133, the connecting pipe 6133 already contains the first heat exchange medium. In order to disassemble the connecting pipe 6133 more conveniently, the vent 730 can be opened first through the first switch 750 to balance the air pressure inside and outside the connecting pipe 6133, and then the exhaust port 740 can be opened through the second switch 760 to release the first heat exchange medium inside the connecting pipe 6133.

[0206] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the first tube 6131 has a first connecting end 61311 located within the first compartment 100, and the second tube 6132 has a second connecting end 61321 located within the second compartment 200. A connecting tube 6133 is detachably connected to the first connecting end 61311 and the second connecting end 61321. The first compartment 100 has a first wall 110, and the second compartment 200 has a second wall 210. The first wall 110 and the second wall 210 are disposed opposite to each other along a first direction. The connecting tube 6133 passes through the first wall 110 and the second wall 210.

[0207] The first connection end 61311 is the end of the first tube body 6131 used to connect with the connecting tube 6133. The first connection end 61311 is also the end of the first tube body 6131 away from the thermal management module 500. The first connection end 61311 is housed in the first compartment 100.

[0208] Optionally, the first pipe body 6131 includes a first pipe body and a first throttling device 710. The first pipe body is connected to the thermal management module 500. The first throttling device 710 and the first pipe body are connected by a clamp 63. The end of the first throttling device 710 away from the first pipe body forms a first connection end 61311.

[0209] The second connection end 61321 is the end of the second tube body 6132 used to connect with the connecting tube 6133. The second connection end 61321 is also the end of the second tube body 6132 away from the second thermal management component 410. The second connection end 61321 is housed within the second compartment 200.

[0210] Optionally, the second pipe body 6132 includes a second pipe body and a second shut-off device 720. The second pipe body and the second thermal management component 410 are connected. The second shut-off device 720 and the second pipe body are connected by a clamp 63. The end of the second shut-off device 720 away from the second pipe body forms a second connection end 61321.

[0211] The first wall 110 is the wall of the first compartment 100 facing the second compartment 200, and it is also the wall of the first compartment 100 closest to the second compartment 200. When the first direction is the height direction, and the first compartment 100 is stacked on top of the second compartment 200, the first wall 110 is the wall of the first compartment 100 located at the bottom of the first compartment 100 along the height direction. The first wall 110 can provide support for the components inside the first compartment 100.

[0212] The second wall 210 is the wall of the second compartment 200 facing the first compartment 100, and it is also the wall of the second compartment 200 closest to the first compartment 100. Along a first direction, the first wall 110 and the second wall 210 are positioned opposite each other. When the first direction is the height direction, and the first compartment 100 is stacked on top of the second compartment 200, the second wall 210 is the wall of the second compartment 200 located at the top of the second compartment 200 along the height direction. The second wall 210 can reduce the risk of external impurities entering the second compartment 200.

[0213] A first mounting hole 111 can be provided on the first wall 110. The first mounting hole 111 is a through hole that penetrates the first wall 110 along a first direction. A second mounting hole 211 can be provided on the second wall 210. The second mounting hole 211 is a through hole that penetrates the second wall 210 along a first direction. One end of the connecting pipe 6133 is detachably connected to the first connecting end 61311. The other end of the connecting pipe 6133 passes through the first mounting hole 111 and the second mounting hole 211 into the second compartment 200 and is detachably connected to the second connecting end 61321.

[0214] The first connecting end 61311 of the first tube 6131 is housed within the first compartment 100, and the second connecting end 61321 of the second tube 6132 is housed within the second compartment 200. One end of the connecting tube 6133 is detachably connected to the first connecting end 61311, and the other end of the connecting tube 6133 passes through the first wall 110 and the second wall 210 and is detachably connected to the second connecting end 61321. During transportation, the connecting tube 6133 can be detached from the first connecting end 61311 and the second connecting end 61321. At this time, the first connecting end 61311 is housed within the first compartment 100, and the second connecting end 61321 is housed within the second compartment 200. When transporting the first compartment 100 and the second compartment 200 respectively, the first connecting end 61311 and the second connecting end 61321 are less likely to interfere with the transportation equipment, which helps to reduce transportation difficulty and transportation costs.

[0215] In some embodiments, at least one of the first tube 6131, the second tube 6132, and the connecting tube 6133 includes a deformable tube.

[0216] Only one of the first pipe body 6131, the second pipe body 6132, and the connecting pipe 6133 may include a deformable pipe; for example, the connecting pipe 6133 may include a deformable pipe. Two of the first pipe body 6131, the second pipe body 6132, and the connecting pipe 6133 may include deformable pipes; for example, both the first pipe body 6131 and the second pipe body 6132 may include deformable pipes. Alternatively, all three pipe bodies may include deformable pipes.

[0217] When the first tube body 6131 includes a deformable tube, the end of the first tube body 6131 used to connect with the connecting tube 6133 may be a deformable tube, while the other part may be a rigid tube. Alternatively, the entire first tube body 6131 may be a deformable tube. Or, the end of the first tube body 6131 used to connect with the connecting tube 6133 may be a rigid tube, while the other part may include a deformable tube.

[0218] When the second tube body 6132 includes a deformable tube, the end of the first tube body 6131 used to connect with the connecting tube 6133 may be a deformable tube, while the other parts may be rigid tubes. Alternatively, the second tube body 6132 may be entirely a deformable tube, or the end of the second tube body 6132 used to connect with the connecting tube 6133 may be a rigid tube, while the other parts may include deformable tubes.

[0219] When the connecting pipe 6133 includes a deformable pipe, the end of the connecting pipe 6133 for connecting to the first pipe body 6131 and / or the end of the connecting pipe 6133 for connecting to the second pipe body 6132 may be a deformable pipe, while the other parts may be rigid pipes. Alternatively, the connecting pipe 6133 may be a deformable pipe as a whole. Or, the end of the connecting pipe 6133 for connecting to the first pipe body 6131 and / or the end of the connecting pipe 6133 for connecting to the second pipe body 6132 may be a rigid pipe, while the other parts may be deformable pipes (for example, the middle part of the connecting pipe 6133 may be a deformable pipe, and both ends may be rigid pipes).

[0220] It's important to clarify that "deformable tubing" here refers to tubing that is easily bent or extended (and not easily damaged after bending or extending). For example, deformable tubing can be flexible hoses or extendable tubing. Flexible hoses are typically composed of multiple layers of materials, such as PVC and rubber, and are flexible. Extendable tubing can be corrugated pipes, etc. "Rigid tubing," on the other hand, refers to tubing that is difficult to bend or extend (and easily damaged after bending or extending). Rigid tubing is usually made of a single material. For example, rigid tubing can be aluminum, copper, iron, steel, or other metal pipes. Flexible hoses and extendable tubing are easier to assemble than rigid tubing.

[0221] Optionally, the first tube 6131, the second tube 6132, and the connecting tube 6133 all include deformable tubes. In some embodiments, the deformable tube is a corrugated tube. The end of the first tube 6131 for connecting to the connecting tube 6133 is a metal tube, and the other part includes a corrugated tube. The end of the second tube 6132 for connecting to the connecting tube 6133 is a metal tube, and the other part includes a deformable tube. The middle part of the connecting tube 6133 is a corrugated tube, and both ends are metal tubes.

[0222] By including at least one of the first tube body 6131, the second tube body 6132, and the connecting tube 6133 as a deformable tube, it is beneficial to absorb manufacturing and assembly errors, thereby facilitating the disassembly and installation of the connecting tube 6133.

[0223] Referring to Figures 1, 2, 3, 4, 5, 6, 7, and 8, in some embodiments, the connecting pipe 6133 includes a first pipe segment 61331, a second pipe segment 61332, and a third pipe segment 61333. At least a portion of the first pipe segment 61331 is located within the first chamber 100 and is detachably connected to the first pipe body 6131. ​​At least a portion of the third pipe segment 61333 is located within the second chamber 200 and is detachably connected to the second pipe body 6132. The second pipe segment 61332 connects the first pipe segment 61331 and the third pipe segment 61333. The second pipe segment 61332 includes a deformable tube.

[0224] The first pipe segment 61331 is the part of the connecting pipe 6133 that is detachably connected to the first pipe body 6131. ​​The first pipe segment 61331 is partially or wholly housed within the first compartment 100. Optionally, the first pipe segment 61331 is a rigid pipe to facilitate a sealing connection with the first pipe body 6131. ​​For example, the first pipe segment 61331 is a metal pipe.

[0225] The third pipe section 61333 is the part of the connecting pipe 6133 used for detachable connection with the second pipe body 6132. The third pipe section 61333 is partially or wholly housed within the second compartment 200. Optionally, the third pipe section 61333 is a rigid pipe to facilitate a sealing connection with the second pipe body 6132. For example, the third pipe section 61333 is a metal pipe.

[0226] The second pipe segment 61332 is the part of the connecting pipe 6133 that connects the first pipe segment 61331 and the third pipe segment 61333. The first pipe segment 61331, the second pipe segment 61332, and the third pipe segment 61333 can be an integrally formed structure or a separate structure. At least a portion of the second pipe segment 61332 is a deformable pipe.

[0227] The first pipe segment 61331 is at least partially located within the first compartment 100 and detachably connected to the first pipe body 6131, meaning the end of the first pipe body 6131 connected to the first pipe segment 61331 is located within the first compartment 100. The third pipe segment 61333 is at least partially located within the second compartment 200 and detachably connected to the second pipe body 6132, meaning the end of the second pipe body 6132 connected to the third pipe segment 61333 is located within the second compartment 200. This design minimizes interference between the first pipe body 6131 and the second pipe body 6132 and the transport equipment during the separate transport of the first compartment 100 and the second compartment 200, reducing transport difficulty and costs. The second pipe segment 61332 includes a deformable tube that can absorb manufacturing and assembly errors, facilitating the connection of the first pipe segment 61331 to the first pipe body 6131 and the third pipe segment 61333 to the third pipe body.

[0228] Please refer to Figures 1, 2, 3, 4, 5, 6, 7, and 8. In some embodiments, the second pipe segment 61332 is a deformable pipe.

[0229] Please refer to Figure 8. In the embodiment shown in the figure, the second pipe section 61332 is a deformable pipe as a whole. For example, the second pipe section 61332 is a corrugated pipe.

[0230] The second tube 6132 is a deformable tube as a whole, which allows the second tube 6132 to obtain a larger deformation, thereby facilitating the absorption of manufacturing and assembly errors.

[0231] Please refer to Figure 9, which is a structural schematic diagram of the connecting pipe 6133 provided in some other embodiments of this application. In some other embodiments, the second pipe segment 61332 includes a connecting segment 613323 and a plurality of deformable pipes, wherein the connecting segment 613323 connects two adjacent deformable pipes.

[0232] The second pipe segment 61332 may include two deformable pipes, three deformable pipes, four deformable pipes, or more deformable pipes. One of the deformable pipes is connected to the first pipe segment 61331, and another deformable pipe is connected to the third pipe segment 61333. Each pair of adjacent deformable pipes is connected by a connecting segment 613323.

[0233] The second pipe section 61332 includes multiple deformable tubes, each of which can deform, allowing the second pipe body 6132 to obtain a larger deformation, thereby facilitating the absorption of manufacturing and assembly errors.

[0234] Referring to Figure 9, in some embodiments, the plurality of deformable tubes include a first deformable tube 613321 and a second deformable tube 613322. A connecting segment 613323 is spaced apart from the first tube segment 61331 along a first direction, and a connecting segment 613323 is spaced apart from the third tube segment 61333 along a second direction. The first deformable tube 613321 connects the first tube segment 61331 and the connecting segment 613323, and the second deformable tube 613322 connects the third tube segment 61333 and the connecting segment 613323. The second direction is perpendicular to the first direction.

[0235] Please refer to Figure 9. The second direction is the Y direction shown in the figure.

[0236] Along the first direction, the connecting segment 613323 and the first pipe segment 61331 are spaced apart. It should be noted that the connecting segment 613323 and the first pipe segment 61331 can be arranged opposite each other along the first direction, or the connecting segment 613323 and the first pipe segment 61331 can be staggered along the first direction (the connecting segment 613323 and the first pipe segment 61331 are not opposite each other in the first direction).

[0237] Along the second direction, the connecting segment 613323 and the third pipe segment 61333 are spaced apart. It should be noted that the connecting segment 613323 and the third pipe segment 61333 can be arranged opposite each other along the second direction, or they can be staggered along the second direction (the connecting segment 613323 and the third pipe segment 61333 are not opposite each other in the second direction).

[0238] The first deformable tube 613321 is a deformable tube connecting the first pipe segment 61331 and the connecting segment 613323, and extends generally along a first direction. The second deformable tube 613322 is a deformable tube connecting the third pipe segment 61333 and the connecting segment 613323, and extends generally along a second direction. The first deformable tube 613321 has a larger deformation amount in the direction perpendicular to the first direction, and the second deformable tube 613322 has a larger deformation amount in the direction perpendicular to the second direction.

[0239] In the embodiment shown in Figure 9, it should be noted that the vent 730 and the first switch 750 can be disposed in the first pipe section 61331, the discharge port 740 and the second switch 760 can be disposed in the third pipe section 61333, and the discharge port 740 and the second switch 760 can also be disposed in the connecting section 613323.

[0240] Since the deformation of the deformable tube along its axial direction is relatively small, by setting a first deformable tube 613321 and a second deformable tube 613322, the first deformable tube 613321 connects the first tube body 6131 and the connecting section 613323 that are spaced apart along the first direction, and the second deformable tube 613322 connects the third tube section 61333 and the connecting section 613323 that are spaced apart along the second direction. In this way, the first deformable tube 613321 has a large amount of deformation in the direction perpendicular to the first direction, and the second deformable tube 613322 has a large amount of deformation in the direction perpendicular to the second direction. Thus, the second tube section 61332 can obtain a large amount of deformation in all directions, which facilitates the absorption of manufacturing errors and assembly errors.

[0241] Please refer to Figure 10, which is a schematic diagram of the structure of the connecting pipe 6133 provided in some embodiments of this application. In some embodiments, the plurality of deformable pipes include a first deformable pipe 613321 and a second deformable pipe 613322. The first deformable pipe 613321 is located within the first compartment 100, and the second deformable pipe 613322 is located within the second compartment 200. The first pipe segment 61331 and the connecting segment 613323 are spaced apart along a second direction, and the first deformable pipe 613321 connects the first pipe segment 61331 and the connecting segment 613323. The third pipe segment 61333 and the connecting segment 613323 are spaced apart along the second direction, and the second deformable pipe 613322 connects the third pipe segment 61333 and the connecting segment 613323. The second direction is perpendicular to the first direction.

[0242] Along the second direction, the connecting segment 613323 and the first pipe segment 61331 are spaced apart. It should be noted that the connecting segment 613323 and the first pipe segment 61331 can be arranged opposite each other along the second direction, or the connecting segment 613323 and the first pipe segment 61331 can be staggered along the second direction (the connecting segment 613323 and the first pipe segment 61331 are not opposite each other in the second direction).

[0243] Along the second direction, the connecting segment 613323 and the third pipe segment 61333 are spaced apart. It should be noted that the connecting segment 613323 and the third pipe segment 61333 can be arranged opposite each other along the second direction, or they can be staggered along the second direction (the connecting segment 613323 and the third pipe segment 61333 are not opposite each other in the second direction).

[0244] The first deformable tube 613321 is a deformable tube that connects the first tube segment 61331 and the connecting segment 613323. The first deformable tube 613321 extends generally along the second direction and is housed within the first compartment 100.

[0245] The second deformable tube 613322 is a deformable tube that connects the third tube segment 61333 and the connecting segment 613323. The second deformable tube 613322 extends approximately along the second direction. The first deformable tube 613321 and the second deformable tube 613322 extend in approximately the same direction. The second deformable tube 613322 is housed within the second compartment 200.

[0246] In the embodiment shown in Figure 10, it should be noted that the vent 730 and the first switch 750 can be disposed in the first pipe section 61331, the discharge port 740 and the second switch 760 can be disposed in the third pipe section 61333, and the discharge port 740 and the second switch 760 can also be disposed in the connecting section 613323.

[0247] The first deformable tube 613321 connects the first tube segment 61331 and the connecting segment 613323, which are spaced apart along the second direction. The second deformable tube 613322 connects the third tube segment 61333 and the connecting segment 613323, which are spaced apart along the second direction. In this way, the second tube segment 61332 has a larger deformation in the direction perpendicular to the second direction, which can better absorb the manufacturing error and assembly error in the direction perpendicular to the second direction.

[0248] Please refer to Figure 11, which is a schematic diagram of the structure of the connecting pipe 6133 provided in some embodiments of this application. In some embodiments, the connecting pipe 6133 includes a plurality of second pipe segments 61332, one end of each second pipe segment 61332 being connected to a first pipe segment 61331, and the other end being connected to a third pipe segment 61333. Each second pipe segment 61332 connects the first pipe segment 61331 and the third pipe segment 61333.

[0249] The connecting pipe 6133 may include two second pipe segments 61332, three second pipe segments 61332, four second pipe segments 61332, or more second pipe segments 61332. Each second pipe segment 61332 is connected at both ends to a first pipe segment 61331 and a third pipe segment 61333, respectively, and each second pipe segment 61332 connects the first pipe segment 61331 and the third pipe segment 61333.

[0250] Multiple second pipe segments 61332 can be arranged around the first pipe segment 61331 and the third pipe segment 61333, and multiple second pipe segments 61332 can also be connected between the first pipe segment 61331 and the third pipe segment 61333.

[0251] When designing the second pipe segment 61332, it can be made relatively long. This way, under normal circumstances, the second pipe segment 61332 will be in a bent state when connected to the first pipe segment 61331 and the third pipe segment 61333. When the distance between the first connecting end 61311 and the second connecting end 61321 is greater than the designed distance due to manufacturing or assembly errors, the second pipe segment 61332 can more effectively absorb these manufacturing and assembly errors.

[0252] In the embodiment shown in Figure 11, it should be noted that the vent 730 and the first switch 750 can be disposed in the first pipe section 61331, and the discharge port 740 and the second switch 760 can be disposed in the third pipe section 61333.

[0253] By setting multiple second pipe sections 61332, each second pipe section 61332 is connected to the first pipe section 61331 and the third pipe section 61333, and is in communication with the first pipe section 61331 and the third pipe section 61333. Each second pipe section 61332 can deform, so that the second pipe section 61332 can obtain a large amount of deformation in all directions, thereby facilitating the absorption of manufacturing errors and assembly errors.

[0254] Referring to Figure 11, in some embodiments, the plurality of second pipe segments 61332 include a central pipe segment 613324 and a plurality of edge pipe segments 613325 located around the central pipe segment 613324. The central pipe segment 613324 is located between the first pipe segment 61331 and the third pipe segment 61333, and the plurality of edge pipe segments 613325 are arranged around the first pipe segment 61331 and the third pipe segment 61333.

[0255] The central pipe segment 613324 is a segment of a plurality of second pipe segments 61332 located between the first pipe segment 61331 and the third pipe segment 61333. The plurality of second pipe segments 61332 may include one central pipe segment 613324, two central pipe segments 613324, three central pipe segments 613324, or more central pipe segments 613324.

[0256] Edge pipe segment 613325 is a pipe segment among a plurality of second pipe segments 61332 that connects to the outer periphery of the first pipe segment 61331 and the third pipe segment 61333. The plurality of second pipe segments 61332 may include two edge pipe segments 613325, three edge pipe segments 613325, four edge pipe segments 613325 or more edge pipe segments 613325, which are arranged circumferentially around the first pipe segment 61331 and the third pipe segment 61333.

[0257] It should be noted that the length of the edge pipe segment 613325 is longer than the length of the central pipe segment 613324. When the edge pipe segment 613325 is straight, the central pipe segment 613324 is also straight. When the edge pipe segment 613325 is bent, the central pipe segment 613324 is also bent.

[0258] By setting a central pipe section 613324 and multiple edge pipe sections 613325, the space around the first pipe section 61331 and the third pipe section 61333 is fully utilized, the flow cross-sectional area of ​​the second pipe section 61332 is increased, and the flow resistance of the first heat exchange medium in the second pipe section 61332 is reduced.

[0259] Referring to Figure 11, in some embodiments, the second pipe segment 61332 and the first pipe segment 61331 are detachably connected, and / or the second pipe segment 61332 and the third pipe segment 61333 are detachably connected.

[0260] The second pipe segment 61332 and the first pipe segment 61331 can be quickly connected. For example, the end of the second pipe segment 61332 that is connected to the first pipe segment 61331 is provided with a female connector, and the first pipe segment 61331 is provided with a male connector. Both the female connector and the male connector are quick-connect connectors.

[0261] The second pipe section 61332 and the third pipe section 61333 can be connected by quick-connect fittings. For example, the end of the second pipe section 61332 that is connected to the third pipe section 61333 is provided with a female connector, and the third pipe section 61333 is provided with a male connector. Both the female connector and the male connector are quick-connect fittings.

[0262] By detachably connecting the second pipe segment 61332 and the first pipe segment 61331, during installation, the first pipe segment 61331 can be connected to the first pipe body 6131 first, and then the second pipe segment 61332 can be connected to the first pipe segment 61331. Since the second pipe segment 61332 can deform, it is easier to absorb manufacturing and assembly errors, thus reducing assembly difficulty. Similarly, by detachably connecting the second pipe segment 61332 and the third pipe segment 61333, during installation, the third pipe segment 61333 can be connected to the second pipe body 6132 first, and then the second pipe segment 61332 can be connected to the third pipe segment 61333. Since the second pipe segment 61332 can deform, it is easier to absorb manufacturing and assembly errors, thus reducing assembly difficulty.

[0263] In some embodiments, the second pipe segment 61332 is a flexible hose.

[0264] The second pipe section 61332 can be a nylon hose, rubber hose, etc.

[0265] When the second pipe section 61332 is a flexible hose, the second pipe section 61332 can obtain a large amount of deformation in all directions, which makes it easier to absorb manufacturing errors and assembly errors.

[0266] In some embodiments, the outer diameter of each second pipe segment 61332 is smaller than the outer diameter of the first pipe segment 61331, and / or the outer diameter of each second pipe segment 61332 is smaller than the outer diameter of the third pipe segment 61333.

[0267] "The outer diameter of each second pipe segment 61332 is smaller than the outer diameter of the first pipe segment 61331" means that the maximum outer diameter of each second pipe segment 61332 is smaller than the minimum outer diameter of the first pipe segment 61331.

[0268] "The outer diameter of each second pipe segment 61332 is smaller than the outer diameter of the third pipe segment 61333" means that the maximum outer diameter of each second pipe segment 61332 is smaller than the minimum outer diameter of the third pipe segment 61333.

[0269] When the outer diameter of the second pipe section 61332 is smaller than the outer diameter of the first pipe section 61331, the smaller outer diameter of the second pipe section 61332 makes it more prone to deformation, thus facilitating the absorption of manufacturing and assembly errors. Similarly, when the outer diameter of the second pipe section 61332 is smaller than the outer diameter of the third pipe section 61333, the smaller outer diameter of the second pipe section 61332 makes it more prone to deformation, again facilitating the absorption of manufacturing and assembly errors.

[0270] In some embodiments, a first pipe segment 61331 is provided with a first connector, a third pipe segment 61333 is provided with a second connector, and a second pipe segment 61332 is connected to the first connector and the second connector. The length of the second pipe segment 61332 along its extending direction is greater than the distance between the first connector and the second connector.

[0271] The first connector is a connector disposed on the first pipe segment 61331 and used for connection with the second pipe segment 61332. Optionally, the first connector is a quick-connect connector to facilitate quick connection with the end of the second pipe segment 61332 that is away from the third pipe segment 61333.

[0272] The second connector is a connector located on the third pipe segment 61333 and used for connection with the second pipe segment 61332. Optionally, the second connector is a quick-connect connector to facilitate quick connection with the end of the second pipe segment 61332 that is away from the first pipe segment 61331.

[0273] One end of the second pipe section 61332 is connected to the first connector, and the other end of the second pipe section 61332 is connected to the second connector.

[0274] When the second pipe segment 61332 is straight, its extension direction is a straight line. When the second pipe segment 61332 is bent, its extension direction is the direction of the bend. When measuring the length of the second pipe segment 61332, the measurement should be taken along its extension direction.

[0275] "The distance between the first connector and the second connector" refers to the shortest distance between the first connector and the second connector. It can be measured multiple times and the average value is taken to improve the accuracy of the measurement.

[0276] The length of the second pipe segment 61332 along its extension direction is greater than the distance between the first joint and the second joint, so that under normal circumstances, the second pipe segment 61332 is in a bent state when connected to the first joint and the second joint. When the distance between the first pipe body 6131 and the second pipe body 6132 becomes greater than the design distance due to manufacturing errors and assembly errors, the second pipe segment 61332 gradually straightens until the length of the second pipe segment 61332 along its extension direction is equal to the distance between the first joint and the second joint.

[0277] By making the length of the second pipe segment 61332 along its extension direction greater than the distance between the first joint and the second joint, the second pipe segment 61332 is in a bent state when connected to the first joint and the second joint under normal circumstances. When the distance between the first pipe body 6131 and the second pipe body 6132 is greater than the design distance due to manufacturing errors and assembly errors, the second pipe segment 61332 can more effectively absorb the manufacturing errors and assembly errors.

[0278] In some embodiments, the sum of the flow cross-sectional areas of the plurality of second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the first pipe section 61331, and / or the sum of the flow cross-sectional areas of the plurality of second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the third pipe section 61333.

[0279] The flow cross-sectional area of ​​the second pipe section 61332 refers to the area enclosed by the inner circumferential surface of the second pipe section 61332 in a cross-section perpendicular to the extension direction of the second pipe section 61332.

[0280] The flow cross-sectional area of ​​the first pipe section 61331 refers to the area enclosed by the inner circumferential surface of the first pipe section 61331 in a cross-section perpendicular to the extension direction of the first pipe section 61331.

[0281] "The sum of the flow cross-sectional areas of multiple second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the first pipe section 61331" means that the sum of the flow cross-sectional areas of all second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the first pipe section 61331.

[0282] The flow cross-sectional area of ​​the third pipe section 61333 refers to the area enclosed by the inner circumferential surface of the third pipe section 61333 in a cross-section perpendicular to the extension direction of the third pipe section 61333.

[0283] "The sum of the flow cross-sectional areas of multiple second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the third pipe section 61333" means that the sum of the flow cross-sectional areas of all second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the third pipe section 61333.

[0284] By ensuring that the sum of the flow cross-sectional areas of the multiple second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the first pipe section 61331, it is beneficial to reduce the flow resistance of the first heat exchange medium in the second pipe section 61332. Similarly, by ensuring that the sum of the flow cross-sectional areas of the multiple second pipe sections 61332 is greater than or equal to the flow cross-sectional area of ​​the third pipe section 61333, it is beneficial to reduce the flow resistance of the first heat exchange medium in the second pipe section 61332.

[0285] Please refer to Figures 1, 2, and 12. Figure 12 is a schematic diagram of the structure of the connecting pipe 6133 passing through the first wall 110 and the second wall 210 according to some embodiments of this application. The first compartment 100 has a first wall 110, and the second compartment 200 has a second wall 210. The first wall 110 and the second wall 210 are arranged opposite to each other along a first direction. The second pipe segment 61332 passes through the first wall 110 and the second wall 210.

[0286] A first mounting hole 111 can be provided on the first wall 110, and the first mounting hole 111 is a through hole that penetrates the first wall 110 along a first direction. A second mounting hole 211 can be provided on the second wall 210, and the second mounting hole 211 is a through hole that penetrates the second wall 210 along a first direction. The second pipe segment 61332 passes through the first mounting hole 111 and the second mounting hole 211.

[0287] The second pipe segment 61332 passes through the first wall 110 and the second wall 210. The first pipe segment 61331 is located within the first compartment 100 and is detachably connected to the first pipe body 6131, facilitating connection between the first pipe segment 61331 and the first pipe body 6131 and reducing the risk of interference between the first pipe segment 61331 and other components. The third pipe segment 61333 is located within the second compartment 200 and is detachably connected to the second pipe body 6132, facilitating connection between the third pipe segment 61333 and the second pipe body 6132 and reducing the risk of interference between the third pipe segment 61333 and other components.

[0288] In some embodiments, the energy storage system 10 includes a communication component 800, which is connected to a first wall 110 and a second wall 210, and a second pipe segment 61332 passes through the communication component 800.

[0289] The connecting component 800 is used to connect the first wall 110 and the second wall 210. The connecting component 800 has a receiving space in which at least a portion of the second pipe segment 61332 is received. In other words, the connecting component 800 is disposed around the outside of the second pipe segment 61332.

[0290] By setting up a connecting component 800 and having the second pipe segment 61332 pass through the connecting component 800, the connecting component 800 can protect the second pipe segment 61332 and reduce the risk of damage to the second pipe segment 61332.

[0291] In some embodiments, the communication component 800 includes a first connector 810 and a second connector 820. The first connector 810 is connected to a first wall 110 and is disposed around a second pipe segment 61332. A second connector 820 is disposed on a second wall 210, and the second connector 820 is sealed to the second wall 210 and is disposed around the second pipe segment 61332. The energy storage system 10 also includes a third seal 830, which seals the first connector 810 and the second connector 820.

[0292] The first connector 810 is a cylindrical structure connected to the first wall 110, and the second pipe section 61332 is at least partially inserted inside the first connector 810.

[0293] Optionally, the first connector 810 is bolted to the first wall 110.

[0294] The second connector 820 is a cylindrical structure connected to the second wall 210, and the second pipe section 61332 passes through the second connector 820. The second connector 820 is sealed to the second wall 210. This sealing connection can be achieved by providing a sealing element between the second connector 820 and the second wall 210, or by welding the second connector 820 to the second wall 210.

[0295] The third seal 830 is used to seal the gap between the first connector 810 and the second connector 820. The third seal 830 is a structure that can achieve a sealing effect, such as sealant, gasket, or sealing sheet.

[0296] By providing a first connector 810 and a second connector 820, the first connector 810 and the second connector 820 together define a protective space. The second pipe segment 61332 passes through this protective space, providing better protection for the second pipe segment 61332 and reducing the risk of damage to it. By sealing the second connector 820 to the second wall 210, the risk of rainwater or other liquids entering the second compartment 200 through the gap between the second connector 820 and the second wall 210 is reduced. A third seal 830 seals the first connector 810 and the second connector 820, further reducing the risk of rainwater or other liquids entering the second compartment 200 through the gap between the first connector 810 and the second connector 820.

[0297] Optionally, both the first connector 810 and the second connector 820 are arranged around the second pipe segment 61332.

[0298] In some embodiments, the first tube 6131 includes a first flow-blocking device 710, the second tube 6132 includes a second flow-blocking device 720, and the connection position of the first tube 6131 and the second tube 6132 is located between the first flow-blocking device 710 and the second flow-blocking device 720.

[0299] Optionally, the first pipe body 6131 is connected to the first flow-blocking device 710 via a clamp 63. The second pipe body 6132 is connected to the second flow-blocking device 720 via a clamp 63.

[0300] When the first flow-blocking device 710 is open, it allows the first heat exchange medium to flow from the thermal management module 500 to the second pipe body 6132 through the first flow-blocking device 710. When the first flow-blocking device 710 is closed, it prevents the first heat exchange medium from flowing from the thermal management module 500 to the second pipe body 6132 through the first flow-blocking device 710. The first flow-blocking device 710 can be a butterfly valve, ball valve, electric valve, self-sealing joint, etc.

[0301] When the second shut-off device 720 is open, it allows the first heat exchange medium to flow from the second heat management component 410 to the first pipe body 6131 through the second shut-off device 720. When the second shut-off device 720 is closed, it prevents the first heat exchange medium from flowing from the second heat management component 410 to the first pipe body 6131 through the second shut-off device 720. The second shut-off device 720 can be a butterfly valve, ball valve, electric valve, self-sealing joint, etc.

[0302] Since the energy storage system 10 requires commissioning before leaving the factory, the first tube 6131 and the second tube 6132 already contain the first heat exchange medium. When it is necessary to disassemble the first tube 6131 and the second tube 6132, the first throttling device 710 and the second throttling device 720 can be closed first. In this way, most of the first heat exchange medium can be retained in the first tube 6131 and the second tube 6132 during disassembly. During assembly, the first tube 6131 is first connected to the second tube 6132, and then the first throttling device 710 and the second throttling device 720 are opened to connect the first tube 6131 and the second tube 6132, so as to realize the circulation of the first heat exchange medium.

[0303] Referring to Figures 1, 2, and 3, in some embodiments, the first compartment 100 includes a first insulating layer 120, with the first battery device 300 and the thermal management module 500 located on opposite sides of the first insulating layer 120. Along a first direction, the thermal management module 500 is located on the side of the first insulating layer 120 facing away from the second compartment 200.

[0304] Referring to Figures 1 and 2, in the embodiment where the thermal management module 500 is housed within the first compartment 100, the first isolation layer 120 is a partition structure disposed within the first compartment 100. For example, the first isolation layer 120 may be a metal plate.

[0305] In an embodiment where the thermal management module 500 is disposed outside the first compartment 100, the first isolation layer 120 may be a wall of the first compartment 100. For example, when the first direction is the height direction and the first compartment 100 is stacked above the second compartment 200, the first isolation layer 120 may be the top wall of the first compartment 100.

[0306] The first isolation layer 120 separates the thermal management module 500 and the first battery device 300, which helps to reduce the risk of interference between the thermal management module 500 and the first battery device 300, thereby improving the reliability of the energy storage system 10.

[0307] Please refer to Figures 1, 2, 3, and 13. Figure 13 is a schematic diagram of the structure of the main pipe 611 passing through the first isolation layer 120 according to some embodiments of this application. In some embodiments, the piping system 600 includes an inlet pipe 610 and a return pipe 620. The inlet pipe 610 is used to supply the first heat exchange medium from the thermal management module 500 to the first thermal management component 310 and the second thermal management component 410. The return pipe 620 is used to supply the first heat exchange medium from the first thermal management component 310 and the second thermal management component 410 to the thermal management module 500. The inlet pipe 610 and / or the return pipe 620 both include a first pipe body 6131 and a second pipe body 6132. The first isolation layer 120 is provided with a first outlet hole 121 through which the inlet pipe 610 and / or the return pipe 620 pass.

[0308] The liquid inlet pipe 610 serves as both the liquid inlet channel for the first thermal management component 310 and the liquid inlet channel for the second thermal management component 410, enabling the first heat exchange medium to flow from the thermal management module 500 to the first thermal management component 310 and the second thermal management component 410.

[0309] The return liquid pipeline 620 serves as both a return liquid channel housed in the first thermal management component 310 and a return liquid channel in the second thermal management component 410, enabling the first heat exchange medium to flow from the first thermal management component 310 to the thermal management module 500, and from the second thermal management component 410 to the thermal management module 500.

[0310] The first isolation layer 120 is provided with a first outlet hole 121. The first outlet hole 121 is a through hole that penetrates the first isolation layer 120 along the first direction. The liquid inlet pipe 610 and the liquid return pipe 620 can be respectively installed in two first outlet holes 121, or the liquid inlet pipe 610 and the liquid return pipe 620 can be installed in the same first outlet hole 121.

[0311] The liquid inlet pipe 610 can pass through a second outlet hole and connect to the thermal management module 500, the first thermal management component 310 and the second thermal management component 410, so that the first heat exchange medium can flow from the thermal management module 500 to the first thermal management component 310 and the second thermal management component 410. The liquid return pipe 620 can pass through another second outlet hole and connect to the thermal management module 500, the first thermal management component 310 and the second thermal management component 410, so that the first heat exchange medium can flow from the first thermal management component 310 and the second thermal management component 410 to the thermal management module 500, thereby realizing the circulation of the first heat exchange medium.

[0312] Referring to Figures 1, 2, 3, and 13, in some embodiments, the inlet pipe 610 and / or return pipe 620 include a main pipe 611, a first main pipe 612, and a second main pipe 613. One end of the main pipe 611 is connected to the thermal management module 500, and the other end of the main pipe 611 passes through the first outlet hole 121 and is connected to the first main pipe 612 and the second main pipe 613. The first main pipe 612 communicates with the thermal management component of the first battery device 300, and the second main pipe 613 communicates with the thermal management component of the second battery device 400. The second main pipe 613 includes a first tube body 6131 and a second tube body 6132.

[0313] The first outlet hole 121 is a through hole provided in the first isolation layer 120, and the first outlet hole 121 penetrates the first isolation layer 120 along the first direction. The first outlet hole 121 is used to pass through the main pipe 611.

[0314] The main pipe 611 connects the heat management module 500, the first main pipe 612, and the second main pipe 613. A portion of the main pipe 611 passes through the first outlet hole 121. One end of the main pipe 611 is connected to the heat management module 500, and the other end of the main pipe 611 passes through the first outlet hole 121 and is connected to the first main pipe 612 and the second main pipe 613, so that the first heat exchange medium output by the heat management module 500 is distributed to the first main pipe 612 and the second main pipe 613 through the main pipe 611.

[0315] The first main pipe 612 connects the main pipe 611 and the first thermal management component 310. The first heat exchange medium output by the thermal management module 500 can flow into the first thermal management component 310 through the main pipe 611 and the first main pipe 612 to exchange heat with the battery cells 320 of the first battery device 300.

[0316] The second main pipe 613 connects to the main pipe 611 and the second thermal management component 410. The first heat exchange medium output by the thermal management module 500 can flow into the second thermal management component 410 through the main pipe 611 and the second main pipe 613 to exchange heat with the battery cells 320 of the second battery device 400.

[0317] One end of the main pipe 611 is connected to the thermal management module 500, and the other end of the main pipe 611 passes through the first lead hole 121 and is connected to the first main pipe 612 and the second main pipe 613. In this way, only the main pipe 611 needs to pass through the first isolation layer 120, while the first main pipe 612 and the second main pipe 613 do not need to pass through the first isolation layer 120, which helps to reduce the number of holes.

[0318] In some embodiments, the energy storage system 10 includes a fourth seal 123, which seals a main pipe 611 and a first isolation layer 120.

[0319] The fourth seal 123 is used to seal the gap between the main pipe 611 and the first isolation layer 120.

[0320] The fourth sealing element 123 is a structure that can achieve a sealing function, such as sealant, gasket, or sealing sheet.

[0321] By providing a fourth seal 123, the main pipe 611 and the first insulating layer 120 can be sealed, reducing the risk of rainwater and other liquids entering the side of the first insulating layer 120 facing the first battery device 300.

The main pipe 611 is provided with a second flange 6111, and the second flange 6111 is sealed together with the main pipe 611. Both the first flange 122 and the second flange 6111 are arranged around the main pipe 611, and a fourth sealing element 123 is disposed between the first flange 122 and the second flange 6111.

[0323] The first flange 122 can be partially accommodated in the first outlet hole 121. The first flange 122 can be welded to the first isolation layer 120 to achieve a sealed connection between the first flange 122 and the first isolation layer 120.

[0324] The second flange 6111 can be a slip-on flange, a welding flange, a socket flange, a loose flange, a threaded flange, or an integral flange. The second flange 6111 is sealed to the main pipe 611 to reduce the risk of rainwater or other liquids entering the first compartment 100 through the gap between the second flange 6111 and the main pipe 611.

[0325] The first flange 122 and the second flange 6111 are both arranged around the outside of the main pipe 611, and the fourth seal 123 is clamped between the first flange 122 and the second flange 6111. Referring to Figure 13, in the embodiment shown in the figure, the first flange 122 and the second flange 6111 are bolted together, and the fourth seal 123 is clamped between the first flange 122 and the second flange 6111.

[0326] The first flange 122 and the first insulating layer 120 are sealed together to reduce the risk of rainwater or other liquids entering the side of the first insulating layer 120 facing the first battery device 300 through the gap between the first flange 122 and the first insulating layer 120. The second flange 6111 is sealed together with the main pipe 611 to reduce the risk of rainwater or other liquids entering the side of the first insulating layer 120 facing the first battery device 300 through the gap between the second flange 6111 and the main pipe 611. A fourth seal 123 is disposed between the first flange 122 and the second flange 6111 to reduce the risk of rainwater or other liquids entering the side of the first insulating layer 120 facing the first battery device 300 through the gap between the first flange 122 and the second flange 6111.

[0327] Referring to Figures 1, 2, and 3, in some embodiments, the first compartment 100 houses a plurality of first battery devices 300 arranged in rows and columns. The plurality of first battery devices 300 in each row are arranged along the length of the first compartment 100, and the plurality of first battery devices 300 in each column are arranged along the height. The inlet pipe 610 and / or return pipe 620 further include a plurality of first branches 614, each first branch 614 communicating with the thermal management components of the plurality of first battery devices 300 in a column. The first main pipe 612 connects the plurality of first branches 614 and the main pipe 611. And / or the second compartment 200 houses a plurality of second battery devices 400 arranged in rows and columns, the plurality of second battery devices 400 in each row arranged along the length of the second compartment 200, and the plurality of second battery devices 400 in each column arranged along the height.

[0328] The first compartment 100 contains multiple rows of first battery devices 300. Each row of first battery devices 300 includes multiple first battery devices 300, which are arranged along the height direction and connected in series to form a battery cluster. In other words, the first compartment 100 contains multiple battery clusters, which are arranged along the length direction of the first compartment 100.

[0329] The first branch 614 is used to connect the first main pipe 612 and the first thermal management component 310 of a plurality of first battery devices 300 in a battery cluster. The first heat exchange medium output by the thermal management module 500 can be distributed through the main pipe 611, the first main pipe 612, and the first branch 614 to the first thermal management component 310 of the plurality of first battery devices 300 in a battery cluster to exchange heat with the battery cells 320 of the first battery devices 300.

[0330] The second compartment 200 contains multiple rows of second battery devices 400. Each row of second battery devices 400 includes multiple second battery devices 400, which are arranged along the height direction and connected in series to form a battery cluster. In other words, the second compartment 200 contains multiple battery clusters, which are arranged along the length direction of the second compartment 200.

[0331] The second branch 615 is used to connect the second main pipe 613 and the second thermal management component 410 of multiple second battery devices 400 in a battery cluster. The first heat exchange medium output by the thermal management module 500 can be distributed through the main pipe 611, the second main pipe 613, and the second branch 615 to the second thermal management component 410 of multiple second battery devices 400 in a battery cluster to exchange heat with the battery cells 320 of the second battery devices 400.

[0332] The first main pipe 612 connects to multiple first branch pipes 614 and the main pipe 611. Each first branch pipe 614 is connected to the thermal management components of multiple first battery devices 300 in a row. The thermal management module 500 can provide a first heat exchange medium to the main pipe 611. The first heat exchange medium is provided to the thermal management components of multiple first battery devices 300 through the main pipe 611, the first main pipe 612 and the multiple first branch pipes 614 respectively, so that the temperature of the first heat exchange medium entering the thermal management components of multiple first battery devices 300 is more uniform, reducing the risk of temperature runaway of battery cells 320. Similarly, the second main pipe 613 connects to multiple second branches 615 and the main pipe 611. Each second branch 615 is connected to the thermal management components of multiple second battery devices 400 in a row. The thermal management module 500 can provide a first heat exchange medium to the main pipe 611. The first heat exchange medium is provided to the thermal management components of multiple second battery devices 400 through the main pipe 611, the second main pipe 613 and the multiple second branches 615 respectively, so that the temperature of the first heat exchange medium entering the thermal management components of multiple second battery devices 400 is more uniform, reducing the risk of temperature runaway of the battery cell 320.

[0333] Please refer to Figure 14, which is a schematic diagram of the structure of a first heat exchange loop 330, a second heat exchange loop 42, and a third heat exchange loop 590 provided in some embodiments of this application. In some embodiments, the thermal management module 500 further includes a pumping device 530, a first heat exchanger 540, a second heat exchanger 510, a compressor 550, and a throttling device 560. The pumping device 530, the first heat exchanger 540, and the first thermal management component 310 are connected through a piping system 600 to form the first heat exchange loop 330. The pumping device 530, the first heat exchanger 540, and the second thermal management component 410 are connected through a piping system 600 to form the second heat exchange loop 42, which includes a first pipe body 6131 and a second pipe body 6132. The compressor 550, the second heat exchanger 510, the throttling device 560 and the heat exchanger are connected to form a third heat exchange loop 590, which is used to exchange heat with the first heat exchange loop 330 and the second heat exchange loop 42.

[0334] The pumping device 530, the first heat exchanger 540, the first thermal management component 310, and the pumping device 530 can be connected sequentially to form a first heat exchange loop 330. However, the connection order of the pumping device 530, the first heat exchanger 540, the first thermal management component 310, and the pumping device 530 is not limited to this; it can be any other reasonable connection order. For example, the pumping device 530, the first thermal management component 310, the first heat exchanger 540, and the pumping device 530 can be connected sequentially to form the first heat exchange loop 330.

[0335] The first heat exchanger 540 is a component used for heat exchange with a first heat exchange medium flowing through it. The first heat exchanger 540 may be, but is not limited to, a plate heat exchanger, a shell-and-tube heat exchanger, an air cooler, a spiral plate heat exchanger, a heat exchange tube bundle, etc. The first heat exchange medium is a coolant, for example, it may be, but is not limited to, a mixture of ethylene glycol and water.

[0336] By adopting the above scheme, the first heat exchange medium can circulate through the first thermal management component 310 to exchange heat with the battery cell 320 and cool the battery cell 320; after exchanging heat with the battery cell 320, the first heat exchange medium can also circulate through the first heat exchanger 540 and exchange heat with the first heat exchanger 540, and exchange the heat exchanged from the battery cell 320 to the first heat exchanger 540, so that the first heat exchange medium is cooled down.

[0337] The pumping device 530, the first heat exchanger 540, the second thermal management component 410, and the pumping device 530 can be connected in sequence to form a second heat exchange loop 42. Of course, the connection order of the pumping device 530, the first heat exchanger 540, the second thermal management component 410, and the pumping device 530 is not limited to this; it can be any other reasonable connection order. For example, the pumping device 530, the second thermal management component 410, the first heat exchanger 540, and the pumping device 530 can be connected in sequence to form the second heat exchange loop 42.

[0338] By adopting the above scheme, the first heat exchange medium can circulate through the second thermal management component 410 to exchange heat with the battery cell 320 and cool the battery cell 320; after exchanging heat with the battery cell 320, the first heat exchange medium can also circulate through the first heat exchanger 540 and exchange heat with the first heat exchanger 540, and exchange the heat exchanged from the battery cell 320 to the first heat exchanger 540, so that the first heat exchange medium is cooled down.

[0339] The compressor 550, the second heat exchanger 510, the throttling device 560, the first heat exchanger 540, and the compressor 550 are connected to form a third heat exchange loop 590. Of course, the connection order of the compressor 550, the second heat exchanger 510, the throttling device 560, the first heat exchanger 540, and the compressor 550 is not limited to this and can be any other reasonable connection order.

[0340] Compressor 550 is a component that provides power for the circulation of the second heat exchange medium and is capable of cooling the second heat exchange medium. Throttling device 560 is a component used for cooling and pressure reduction; throttling device 560 can be, but is not limited to, a throttling valve, an expansion valve, etc. Second heat exchanger 510 is a component used for heat exchange with the second heat exchange medium flowing through it. Second heat exchanger 510 can be, but is not limited to, a plate heat exchanger, a shell-and-tube heat exchanger, an air cooler, a spiral plate heat exchanger, a heat exchange tube bundle, etc. The second heat exchange medium has a low boiling point and heat of vaporization, and can evaporate and condense at relatively low temperatures. It achieves a cooling effect by absorbing and releasing heat; that is, the second heat exchange medium is a refrigerant. For example, the second heat exchange medium can be, but is not limited to, Freon, ammonia, carbon dioxide, R134A (1,1,1,2-tetrafluoroethane), R410A (Freon R-410A refrigerant), etc.

[0341] The first heat exchanger 540 is located in the first heat exchange loop 330, the second heat exchange loop 42, and the third heat exchange loop 590. The first heat exchanger 540 internally has a first heat exchange medium flow channel and a second heat exchange medium flow channel. The first heat exchange medium flow channel participates in forming the first heat exchange loop 330, through which the first heat exchange medium flows. The second heat exchange medium flow channel participates in forming the third heat exchange loop 590, through which the second heat exchange medium flows. The first and second heat exchange medium flow channels are not interconnected to prevent mixing. In the first heat exchanger 540, the first and second heat exchange media can exchange heat, particularly the heat from the first heat exchange medium can be transferred to the second heat exchange medium, allowing the first heat exchanger 540 to cool the first heat exchange medium flowing through it.

[0342] In some embodiments, the second heat exchanger 510 is a condenser. The thermal management module 500 also includes a fan 520 that dissipates heat from the condenser.

[0343] In some embodiments, the thermal management module 500 further includes a liquid storage tank 570 for containing a second heat exchange medium. The compressor 550, second heat exchanger 510, liquid storage tank 570, throttling device 560, first heat exchanger 540, and compressor 550 are connected to form a third heat exchange loop 590. Of course, the connection order of the compressor 550, second heat exchanger 510, liquid storage tank 570, throttling device 560, first heat exchanger 540, and compressor 550 is not limited to this and can be any other reasonable connection order.

[0344] In some embodiments, the thermal management module 500 further includes an expansion tank 580, which is disposed in the first heat exchange loop 330 and the second heat exchange loop 42.

[0345] The expansion tank 580 is a component that, when the fluid pressure in the system decreases, causes the gas pressure inside the expansion tank 580 to exceed the fluid pressure, resulting in gas expansion that forces the fluid out of the bladder and replenishes the system. When the fluid pressure in the system increases, the fluid enters the bladder of the expansion tank 580, compressing the nitrogen gas sealed inside. This compression reduces the gas volume and increases its pressure until the gas pressure inside the expansion tank 580 matches the fluid pressure in the system, at which point fluid entry into the bladder ceases. When the fluid pressure in the system decreases, the gas pressure inside the expansion tank 580 exceeds the fluid pressure, causing the gas expansion to force the fluid out of the bladder and replenish the system.

[0346] By incorporating the expansion tank 580, on the one hand, the expansion tank 580 can act as a buffer between the first heat exchange circulation loop 330 and the second heat exchange circulation loop 42. When the first heat exchange medium expands due to heat, it absorbs a portion of the first heat exchange medium; when the first heat exchange medium contracts due to cold, it replenishes the first heat exchange medium, thereby improving the stability of the first heat exchange medium's flow. On the other hand, after the connecting pipe 6133 is installed, air may be present within the connecting pipe 6133. The expansion tank 580 can absorb this air, allowing the first heat exchange medium to circulate normally in the first heat exchange circulation loop 330 and the second heat exchange circulation loop 42.

[0347] The first heat exchange loop 330 can perform thermal management on the first battery device 300, the second heat exchange loop 42 can perform thermal management on the second battery device 400, and the third heat exchange loop 590 can perform heat exchange on the first heat exchange medium passing through the first heat exchanger 540, so that the first heat exchange medium has a better heat exchange effect on the first battery device 300 and the second battery device 400.

[0348] Please refer to Figures 1 and 2. The first direction is the height direction, and the first compartment 100 is located above the second compartment 200.

[0349] When the first direction is the height direction, the first compartment 100 is stacked on top of the second compartment 200 along the height direction. The second compartment 200 can support the first compartment 100, which helps to reduce the footprint of the energy storage system 10.

[0350] By setting up a first compartment 100 and a second compartment 200, the first battery device 300 is housed in the first compartment 100 and the second battery device 400 is housed in the second compartment 200. The first compartment 100 and the second compartment 200 are stacked along the height direction, which can reduce the floor space of the energy storage system 10, thereby increasing the energy per unit floor space of the energy storage system 10 and improving the area energy density of the energy storage system 10.

[0351] Referring to Figures 1 and 2, in some embodiments, the thermal management module 500 is located inside the first compartment 100 and on top of the first battery device 300.

[0352] "The thermal management module 500 is located inside the first compartment 100 and on top of the first battery device 300" means that the thermal management module 500 is housed inside the first compartment 100, and the thermal management module 500 is located above the first battery device 300 along the height direction, and the projection of the thermal management module 500 along the height direction at least partially covers the first battery device 300.

[0353] By housing the thermal management module 500 within the first compartment 100, the thermal management module 500 can share a portion of the floor space with the first compartment. Given a fixed total energy of the energy storage system 10, the energy storage system 10 can have a smaller volume, resulting in a smaller floor space and thus increasing the energy density per unit area. Furthermore, by placing the thermal management module 500 on top of the first battery device 300, there are fewer obstructions above it, which improves the heat dissipation effect and efficiency of the thermal management module 500, reducing auxiliary power consumption. Additionally, it reduces the impact of solar radiation on the temperature of the first battery device 300, improving the temperature consistency between the first battery device 300 and the second battery device 400.

[0354] In some embodiments, the first direction is the height direction, the dimensions of the first compartment 100 and the second compartment 200 along their length direction are consistent with the dimensions of the standard container along their length direction, the dimensions of the first compartment 100 and the second compartment 200 along their width direction are consistent with the dimensions of the standard container along their width direction, and the dimensions of the first compartment 100 and the second compartment 200 along their height direction are smaller than the dimensions of the standard container along their height direction.

[0355] The dimension of the first compartment 100 along the height direction is also the height of the first compartment 100. Please refer to Figures 1 and 2. In the figures, H1 is used to indicate the dimension of the first compartment 100 along the height direction.

[0356] The dimension of the second compartment 200 along the height direction is also the height of the second compartment 200. Please refer to Figures 1 and 2. In the figures, H2 is used to indicate the dimension of the second compartment 200 along the height direction.

[0357] A standard container can refer to a container of standard dimensions used in transportation, such as 10 feet, 20 feet, 30 feet, 40 feet, or 45 feet. These dimensions conform to the corresponding standards, with specific length, width, and height measurements. Standard containers can be referenced in GB / T1413-2023 Series 1: Container Classification, Dimensions, and Rated Mass.

[0358] A 10-foot dimension can include: a length dimension of 2991mm with a tolerance of 0mm-5mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2438mm or less with a tolerance of 0mm-5mm.

[0359] A 20-foot measurement may include: a length of 6058mm with a tolerance of 0mm-6mm; a width of 2438mm with a tolerance of 0mm-5mm; and a height of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0360] A 30-foot measurement may include: a length dimension of 9125mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0361] A 40-foot dimension may include: a length dimension of 12192mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 0mm-5mm; and a height dimension of 2896mm, 2591mm, or no greater than 2438mm with a tolerance of 0mm-5mm.

[0362] A 45-foot unit can include: a length dimension of 13716mm with a tolerance of 0mm-10mm; a width dimension of 2438mm with a tolerance of 350mm-5mm; and a height dimension of 2591mm or 2896mm with a tolerance of 0mm-5mm.

[0363] In the embodiments of this application, for the first compartment 100 and the second compartment 200 of various sizes, the dimensions within the range of ±1%, ±2%, ±3%, ±4%, and ±5% can be regarded as the dimensions within the tolerance range.

[0364] In some embodiments, the standard container is a 20-foot standard container with a height of 2896 mm, 2591 mm, or 2438 mm. The first compartment 100 has a height dimension of less than 2896 mm, and the second compartment 200 has a height dimension of less than 2896 mm.

[0365] By ensuring that the length dimensions of both the first compartment 100 and the second compartment 200 are identical to those of a standard shipping container, and their width dimensions are also identical to those of a standard shipping container, it is easier to match existing standard container transport vehicles and lifting gear, reducing the transportation cost of the energy storage system 10 and thus lowering its operating cost. When the height dimensions of both the first compartment 100 and the second compartment 200 are smaller than those of a standard shipping container, the total weight of the first compartment 100 and its components, as well as the total weight of the second compartment 200 and its components, can be reduced. This helps to address the issue of overweight transport and further reduces the transportation cost of the energy storage system 10.

[0366] In some embodiments, the dimensions of the first compartment 100 and the second compartment 200 along the height direction are both greater than or equal to one-third times the dimensions of a standard container along the height direction.

[0367] When the dimensions of the first compartment 100 and the second compartment 200 along the height direction are both greater than or equal to one-third times the dimensions of a standard container along the height direction, the energy storage system 10 has high manufacturability and is more convenient to transport and install.

[0368] Optionally, the dimensions of the first compartment 100 and the second compartment 200 along the height direction are both greater than or equal to half the dimensions of a standard container along the height direction.

[0369] When the dimensions of the first compartment 100 and the second compartment 200 along the height direction are both greater than or equal to half the dimensions of a standard shipping container along the height direction, the energy storage system 10 exhibits higher manufacturability, higher volumetric energy density, and easier transportation and installation. For example, when the first compartment 100 and the second compartment 200 are stacked, the height is greater than that of a standard shipping container. The total weight of the first compartment 100 and the components housed within it is relatively low, as is the total weight of the second compartment 200 and the components housed within it. This configuration allows the first compartment 100 and the second compartment 200 to be transported separately, and when stacked at the point of use, the energy storage system 10 has a higher energy capacity.

[0370] In some embodiments, the sum of the dimensions of the first compartment 100 and the second compartment 200 along the height direction is greater than or equal to the dimension of a standard container along the height direction.

[0371] For example, the standard container is a 20-foot standard container with a height of 2896 mm. The sum of the dimension of the first compartment 100 along the height direction and the dimension of the second compartment 200 along the height direction Z is greater than or equal to 2896 mm.

[0372] By making the sum of the dimensions of the first compartment 100 and the second compartment 200 along the height direction greater than or equal to the dimensions of a standard container along the height direction, it is beneficial to increase the power capacity of the energy storage system 10.

[0373] Optionally, the dimensions of the first compartment 100 and the second compartment 200 along the height direction are both greater than or equal to 805 mm and both less than 2896 mm.

[0374] Please refer to Figures 1 and 2. In the figures, H1 is used to indicate the dimension of the first compartment 100 along the height direction, that is, 805mm≤H1≤2896mm.

[0375] The height dimension of the first compartment 100 can be any one of 850mm, 900mm, 950mm, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1300mm, 1400mm, 1500mm, 1600mm, 1800mm, 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, 2600mm, 2700mm, 2800mm, or 2895mm, or a value between any two of them.

[0376] Please refer to Figures 1 and 2. In the figures, H2 indicates the dimension of the second compartment 200 along the height direction, that is, 805mm≤H2≤2896mm.

[0377] The height dimension of the second compartment 200 can be any one of 850mm, 900mm, 950mm, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1300mm, 1400mm, 1500mm, 1600mm, 1800mm, 2000mm, 2100mm, 2200mm, 2300mm, 2400mm, 2500mm, 2600mm, 2700mm, 2800mm, or 2895mm, or a value between any two of them.

[0378] By setting the dimensions of the first compartment 100 along the height direction and the second compartment 200 along the height direction to be greater than or equal to 805 mm and less than 2896 mm, it is beneficial to reduce the total weight of the first compartment 100 and the components inside the first compartment 100, reduce the total weight of the second compartment 200 and the components inside the second compartment 200, and maximize the power of the energy storage system 10, thereby reducing the operating cost of the energy storage system 10.

[0379] Referring to Figures 1 and 2, in some embodiments, the thermal management module 500 is housed inside the first compartment 100, and the dimension of the first compartment 100 along the height direction is larger than the dimension of the second compartment 200 along the height direction.

[0380] In the embodiment where the thermal management module 500 is housed within the first compartment 100, the height of the first compartment 100 is greater than the height of the second compartment 200, i.e., H1 > H2.

[0381] By housing the thermal management module 500 inside the first compartment 100, and making the height dimension of the first compartment 100 larger than that of the second compartment 200, the internal space of the first compartment 100 is increased. This reduces the impact of the thermal management module 500 on the volume of the first battery device 300, ensuring that the first compartment 100 has sufficient space to accommodate both the first battery device 300 and the thermal management module 500. Furthermore, a thermal management module 500 with higher heat dissipation capacity can be placed there, improving thermal management capabilities.

[0382] In some embodiments, the total weight of the first compartment 100 and the components disposed within the first compartment 100 is less than or equal to 36 tons; and / or the total weight of the second compartment 200 and the components disposed within the second compartment 200 is less than or equal to 36 tons.

[0383] Components located within the first compartment 100 include, for example, the first battery device 300, the thermal management module 500, and other components.

[0384] The total weight of the first compartment 100 and the components disposed within the first compartment 100 can be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, or 36 tons, or any combination thereof.

[0385] Components installed inside the second compartment 200, such as the second battery device 400, connecting pipe 6133, etc.

[0386] The total weight of the second compartment 200 and the components disposed within the second compartment 200 can be any one of 10 tons, 15 tons, 20 tons, 25 tons, 30 tons, 35 tons, or 36 tons, or any combination thereof.

[0387] By ensuring that the total weight of the first compartment 100 and the components located within the first compartment 100 is less than or equal to 36 tons, and the total weight of the second compartment 200 and the components located within the second compartment 200 is less than or equal to 36 tons, the transportation limits of some countries are met, thereby reducing transportation difficulty and costs.

[0388] Please refer to Figure 15, which is a schematic diagram of the control system framework in the energy storage system 10 provided in some embodiments of this application. In some embodiments, the energy storage system 10 further includes a control module 910, a first battery monitoring circuit, and a second battery monitoring circuit. The first battery monitoring circuit is used to collect first data from the first battery device 300, and the second battery monitoring circuit is used to collect second data from the second battery device 400. The control module 910 is used to determine the operating status data of the energy storage system 10, and the operating status data of the energy storage system 10 is associated with the first data and the second data.

[0389] The first battery monitoring circuit can be a device used to monitor the individual battery cells 320 in the first battery device 300. The first data acquisition of the first battery device 300 by the first battery monitoring circuit can refer to the first battery monitoring circuit's ability to acquire voltage and temperature data of the individual battery cells 320 in the first battery device 300. These data are the basis for the battery management system to perform state monitoring and control.

[0390] The second battery monitoring circuit can be a device used to monitor the individual battery cells 320 in the second battery device 400. The first data acquisition of the second battery device 400 by the second battery monitoring circuit can refer to the ability of the second battery monitoring circuit to collect voltage and temperature data of the individual battery cells 320 in the second battery device 400. This data is the basis for the battery management system to perform state monitoring and control.

[0391] The control module 910 can be a module in the energy storage system 10 used to monitor and manage the first battery device 300 and the second battery device 400. It can serve as a management unit for the first battery device 300 and the second battery device 400 in the energy storage system 10. The control module 910 can communicate with the first battery monitoring circuit and the second battery monitoring circuit. It can receive and process first data and second data to determine the operating status data of the energy storage system 10. The control module 910 can monitor information such as current, voltage, power, state of charge, or temperature of the energy storage system 10 to determine the operating status data of the energy storage system 10. As an example, the control module 910 includes modules such as an insulation monitoring module (IMM), a master battery management unit (MBMU), an Ethernet (ETH) module, and a fiber optic conversion module.

[0392] The operating status data of the energy storage system 10 determined by the control module 910 is associated with the first data of the first battery device 300 collected by the first battery monitoring circuit and the second data of the second battery device 400 collected by the second battery monitoring circuit. This enables the control module 910 to control the first battery device 300 and the second battery device 400, which helps to reduce the number of control modules 910, maximize the utilization of the control modules 910, and help reduce the cost of the energy storage system 10.

[0393] Referring to Figure 15, in some embodiments, the energy storage system 10 further includes a first sub-control module 920 and a second sub-control module 930. The first sub-control module 920 is communicatively connected between the first battery monitoring circuit and the control module 910, and the second sub-control module 930 is communicatively connected between the second battery monitoring circuit and the control module 910. The first sub-control module 920 is used to forward first data, and the second sub-control module 930 is used to forward second data. Alternatively, the first sub-control module 920 is used to acquire and process the first data and transmit the processed data to the control module 910, and the second sub-control module 930 is used to acquire and process the second data and transmit the processed data to the control module 910.

[0394] The first sub-control module 920 can serve as a battery management unit for a battery cluster formed by multiple first battery devices 300, used for monitoring and managing the battery cluster. The first sub-control module 920 can monitor information such as current, voltage, power, or temperature of the battery cluster. For example, it can control the charging and discharging current and voltage of the battery cluster. The first sub-control module 920 may include modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0395] The second sub-control module 930 can serve as a battery management unit for a battery cluster formed by multiple second battery devices 400, used for monitoring and managing the battery cluster. The second sub-control module 930 can monitor information such as the current, voltage, power, or temperature of the battery cluster. For example, it can control the charging and discharging current and voltage of the battery cluster. The second sub-control module 930 may include modules such as an auxiliary battery management unit (SBMU) and a fusion switch.

[0396] In some embodiments, the first sub-control module 920 is used to forward first data. For example, the first sub-control module 920 can forward information such as the current, voltage, power, state of charge, or temperature of the first battery device 300 to the control module 910. The second sub-control module 930 is used to forward second data. For example, the second sub-control module 930 can forward information such as the current, voltage, power, state of charge, or temperature of the second battery device 400 to the control module 910.

[0397] In other embodiments, the first sub-control module 920 is used to acquire and process first data, and then transmit the processed data to the control module 910. For example, the first sub-control module 920 can process information such as the current, voltage, power, state of charge, or temperature of the first battery device 300 before forwarding it to the control module 910. The second sub-control module 930 is used to acquire and process second data, and then transmit the processed data to the control module 910. For example, the second sub-control module 930 can process information such as the current, voltage, power, state of charge, or temperature of the second battery device 400 before forwarding it to the control module 910.

[0398] By setting a first sub-control module 920 between the first battery monitoring circuit and the control module 910, and setting a second sub-control module 930 between the second battery monitoring circuit and the control module 910, the control system of the energy storage system 10 is made into a three-level framework. This reduces the length and complexity of the communication harness, reduces sampling errors, improves the reliability of the control system, and also reduces the requirements for the processor and communication bus, thus reducing the overall cost of the control system.

[0399] Please refer to Figure 16, which is a schematic diagram of the control system framework in the energy storage system 10 provided in other embodiments of this application. In other embodiments, the first battery monitoring circuit and the control module 910 are directly communicatively connected.

[0400] By directly communicating with the first battery monitoring circuit and the control module 910, and by directly communicating with the second battery monitoring circuit and the control module 910, the energy storage system 10 is configured as a two-level framework. This allows the control module 910 to monitor key parameters such as voltage, current, and temperature of the battery cells 320 in the first battery device 300 and the second battery device 400 in real time. This helps ensure that the battery cells 320 in the first battery device 300 and the second battery device 400 operate in a safe state, reducing the possibility of overcharging, over-discharging, and short circuits, and thus improving the reliability of the energy storage system 10.

[0401] In some embodiments, the control module 910 is housed in the first compartment 100 or the second compartment 200.

[0402] There is only one control module 910. The control module 910 can be housed in the first compartment 100 or the second compartment 200. The first compartment 100 or the second compartment 200 can protect the control module 910 and reduce the risk of damage to the control module 910.

[0403] In some embodiments, the control module 910 is housed within the first compartment 100. The control module 910 being housed within the first compartment 100 can mean that the control module 910 is located within the hollow structure formed by the first compartment 100. This allows control of the battery devices in different compartments to be achieved solely through the control module 910 within the first compartment 100. In case of emergencies, only the operation of the control module 910 within the first compartment 100 is required to handle any unforeseen circumstances in the energy storage system 10. The control module 910 located within the hollow structure of the first compartment 100 can be connected to the wall of the first compartment 100 using bolts, rivets, connecting pins, or other connecting components. Alternatively, it can be first fixed to a shelf, and then the shelf is connected to the wall of the first compartment 100 using bolts, rivets, connecting pins, or other connecting components. This reduces the possibility of the control module 910 moving due to shaking within the hollow structure of the first compartment 100, thus minimizing the possibility of damage to the control module 910.

[0404] In some embodiments, the control module 910 is housed within the second compartment 200. This means the control module 910 is located within the hollow structure of the second compartment 200, allowing control of the battery devices in different compartments to be achieved solely through the control module 910 within the second compartment 200. This enables the handling of emergencies in the energy storage system 10 by operating only the control module 910 within the second compartment 200. The control module 910, located within the hollow structure of the second compartment 200, can be connected to the wall of the second compartment 200 using bolts, rivets, connecting pins, or other connecting components. Alternatively, it can be first fixed to a shelf, and then the shelf is connected to the wall of the second compartment 200 using bolts, rivets, connecting pins, or other connecting components. This reduces the possibility of the control module 910 moving due to shaking within the hollow structure of the second compartment 200, thus minimizing the possibility of damage to the control module 910.

[0405] In an embodiment where the first direction is the height direction and the first compartment 100 is stacked on top of the second compartment 200, the control module 910 can be accommodated in the second compartment 200 to reduce the height of the control module 910, which facilitates the operation of the control module 910 by the staff and makes it easier for the staff to handle emergencies in a timely manner.

[0406] Please refer to Figure 17, which is a schematic block diagram of a disassembly method for an energy storage system 10 provided in some embodiments of this application. This application also provides a disassembly method 20 for an energy storage system, used to disassemble the aforementioned energy storage system 10. The disassembly method 20 includes:

[0407] Disconnection step S100: Separate the first tube body 6131 and the second tube body 6132;

[0408] Separation step S200: Separate the first compartment 100 and the second compartment 200.

[0409] "Separating the first tube 6131 and the second tube 6132" means disconnecting the connection between the first tube 6131 and the second tube 6132.

[0410] "Separating the first compartment 100 and the second compartment 200" means disconnecting the first compartment 100 and the second compartment 200. In an embodiment where the first direction is the height direction and the first compartment 100 is stacked on top of the second compartment 200, the first compartment 100 stacked on top of the second compartment 200 can also be moved off the second compartment 200.

[0411] It should be noted that the disconnection step S100 can be performed before the separation step S200, or the disconnection step S100 can be performed simultaneously with the separation step S200.

[0412] Please refer to Figure 18, which is a schematic block diagram of a disassembly method for an energy storage system 10 provided in other embodiments of this application. In other embodiments, the piping system 600 further includes a connecting pipe 6133, and the first pipe body 6131 and the second pipe body 6132 are detachably connected through the connecting pipe 6133.

[0413] Disconnection step S100 includes:

[0414] Step S110: Separate the connecting pipe 6133 from the first pipe body 6131, and separate the connecting pipe 6133 from the second pipe body 6132.

[0415] In the disconnection step S100, one end of the connecting tube 6133 is disconnected from the first tube body 6131 to separate the connecting tube 6133 from the first tube body 6131, and the other end of the connecting tube 6133 is disconnected from the second tube body 6132 to separate the connecting tube 6133 from the second tube body 6132.

[0416] By setting a connecting pipe 6133, one end of the connecting pipe 6133 is detachably connected to the first pipe body 6131, and the other end of the connecting pipe 6133 is detachably connected to the second pipe body 6132, which helps to reduce the difficulty of separating the first pipe body 6131 and the second pipe body 6132.

[0417] Please refer to Figure 19, which is a schematic block diagram of a disassembly method for an energy storage system 10 provided in some embodiments of this application. In some embodiments, the first pipe body 6131 includes a first intercepting device 710, and the second pipe body 6132 includes a second intercepting device 720.

[0418] Before disconnection step S100, the energy storage system disassembly method 20 further includes:

[0419] Closing step S300: Close the first flow-blocking device 710 and the second flow-blocking device 720.

[0420] When implementing the dismantling method 20 of the energy storage system, the shutdown step S300 is performed first, followed by the disconnection step S100 and the separation step S200.

[0421] In the closing step S300, the first shut-off device 710 is closed to disconnect the connecting pipe 6133 and the first pipe body 6131, and the second shut-off device 720 is closed to disconnect the connecting pipe 6133 and the second pipe body 6132.

[0422] Since the energy storage system 10 requires commissioning before leaving the factory, the first tube 6131, connecting tube 6133, and second tube 6132 already contain the first heat exchange medium. When it is necessary to disassemble the connecting tube 6133, the first shut-off device 710 and the second shut-off device 720 can be closed first, thereby cutting off the connection between the first tube 6131 and the connecting tube 6133, and the second tube 6132 and the connecting tube 6133. In this way, the first heat exchange medium in the first tube 6131 and the second tube 6132 is less likely to leak when disassembling the connecting tube 6133. During assembly, the connecting tube 6133 is first connected to the first tube 6131 and the second tube 6132, and then the first shut-off device 710 and the second shut-off device 720 are opened, so that the first tube 6131 and the connecting tube 6133 are connected, and the second tube 6132 and the connecting tube 6133 are connected, so as to realize the circulation of the first heat exchange medium.

[0423] Please refer to Figure 20, which is a schematic block diagram of a disassembly method for an energy storage system 10 provided in some embodiments of this application. In some embodiments, after closing step S300 and before disconnecting step S100, the disassembly method 20 for the energy storage system further includes:

[0424] Drainage step S400: Drain the first heat exchange medium in the connecting pipe 6133.

[0425] When implementing the disassembly method 20 of the energy storage system, the following steps are performed: first, the shut-off step S300 is performed; then, the draining step S400 is performed; and finally, the disconnection step S100 and the separation step S200 are performed.

[0426] Before disassembling the connecting pipe 6133, the connecting pipe 6133 already contains the first heat exchange medium. By first draining the first heat exchange medium from the connecting pipe 6133 and then disassembling the connecting pipe 6133, the difficulty of disassembling the connecting pipe 6133 can be reduced.

[0427] Please refer to Figure 21, which is a schematic block diagram of a disassembly method for an energy storage system 10 provided in some embodiments of this application. In some embodiments, the connecting pipe 6133 is provided with a vent 730 and a discharge port 740, with the vent 730 positioned higher than the discharge port 740. The vent 730 is provided with a first switch 750, and the discharge port 740 is provided with a second switch 760. The draining step S400 includes:

[0428] Step S410: Open the vent 730 through the first switch 750 and open the discharge port 740 through the second switch 760 to discharge the first heat exchange medium in the connecting pipe 6133 from the discharge port 740.

[0429] In step S410, the vent 730 is opened by the first switch 750 to balance the air pressure inside and outside the connecting pipe 6133. After the air pressure inside and outside the connecting pipe 6133 is balanced, the discharge port 740 is opened by the second switch 760 to allow the first heat exchange medium inside the connecting pipe 6133 to be discharged from the discharge port 740.

[0430] The first switch 750 opens the vent 730 to balance the air pressure inside and outside the connecting pipe 6133, and then the second switch 760 opens the discharge port 740 to release the first heat exchange medium inside the connecting pipe 6133. This allows for a simple and convenient way to discharge the first heat exchange medium inside the connecting pipe 6133.

[0431] Please refer to Figure 22, which is a schematic block diagram of an installation method for an energy storage system 10 provided in some embodiments of this application. This application also provides an installation method 30 for an energy storage system, used to install the aforementioned energy storage system 10. The installation method 30 includes:

[0432] Arrangement step S10: Arrange the first compartment 100 and the second compartment 200 along the first direction;

[0433] Connection step S20: Connect the first tube body 6131 and the second tube body 6132.

[0434] In the arrangement step S10, the first compartment 100 and the second compartment 200 are arranged along the first direction. The first compartment 100 can be connected to the second compartment 200 through a connector to fix the first compartment 100 and the second compartment 200. When connecting the first compartment 100 to the second compartment 200, a detachable connection is used to facilitate the subsequent movement of the energy storage system 10.

[0435] In the connection step S20, the first tube 6131 and the second tube 6132 are connected together, so that the first tube 6131 and the second tube 6132 are connected.

[0436] Please refer to Figure 23, which is a schematic block diagram of an installation method for an energy storage system 10 provided in other embodiments of this application. In other embodiments, the energy storage system 10 further includes a connecting pipe 6133. The connection step S20 includes:

[0437] Step S21: Connect the first tube body 6131 and the second tube body 6132 through the connecting tube 6133.

[0438] In step S21, one end of the connecting pipe 6133 is connected to the first pipe body 6131, and the other end of the connecting pipe 6133 is connected to the second pipe body 6132. A detachable connection is used when connecting the connecting pipe 6133 and the first pipe body 6131, facilitating the subsequent movement of the energy storage system 10. A detachable connection is also used when connecting the connecting pipe 6133 and the second pipe body 6132, facilitating the subsequent movement of the energy storage system 10.

[0439] By setting a connecting pipe 6133, one end of the connecting pipe 6133 is used to be detachably connected to the first pipe body 6131, and the other end of the connecting pipe 6133 is used to be detachably connected to the second pipe body 6132, thereby reducing the difficulty of installing the first pipe body 6131 and the second pipe body 6132.

[0440] Please refer to Figure 24, which is a schematic block diagram of an installation method for an energy storage system 10 provided in some embodiments of this application.

[0445] Please refer to Figures 1 to 24 for some embodiments of this application.

[0446] This application provides an energy storage system 10, which includes a first compartment 100, a first battery device 300, a second compartment 200, a second battery device 400, a thermal management module 500, and a piping system 600. The first compartment 100 houses the first battery device 300, which includes a first thermal management component 310. The second compartment 200 houses the second battery device 400. The first compartment 100 and the second compartment 200 are stacked along their height, with the first compartment 100 located above the second compartment 200. The second battery device 400 includes a second thermal management component 410. The thermal management module 500 is housed within the first compartment 100. The piping system 600 connects the thermal management module 500, the first thermal management component 310, and the second thermal management component 410. The thermal management module 500 manages the temperature of the first battery device 300 and the second battery device 400. The piping system 600 includes a first pipe body 6131 and a second pipe body 6132. The first pipe body 6131 is connected to the thermal management module 500 and is at least partially housed within the first compartment 100. The second pipe body 6132 is connected to the second thermal management component 410 and is at least partially housed within the second compartment 200. The first pipe body 6131 and the second pipe body 6132 are detachably connected. By setting the first compartment 100 and the second compartment 200, the first battery device 300 is housed within the first compartment 100, and the second battery device 400 is housed within the second compartment 200, which helps to improve the capacity and energy density of the energy storage system 10. The energy storage system 10 achieves thermal management of the first battery device 300 and the second battery device 400 through a single thermal management module 500, which helps to reduce the number of thermal management modules 500, reduce the production cost of the energy storage system 10, reduce the space occupied by the energy storage system 10, and improve the volumetric energy density of the energy storage system 10. The first tube 6131 is connected to the thermal management module 500, and the second tube 6132 is connected to the second thermal management component 410. The first tube 6131 and the second tube 6132 are detachably connected. On one hand, this allows the first heat exchange medium to flow from the thermal management module 500 to the second thermal management component 410 or vice versa, thereby achieving thermal management of the second battery device 400. On the other hand, the detachable connection of the first tube 6131 and the second tube 6132 allows for separation during transportation, facilitating the separate transportation of the first compartment 100 and the second compartment 200, reducing transportation difficulty and costs. Furthermore, by making the first tube 6131 and the second tube 6132 detachably connected, the airtightness of the first tube 6131 and the second tube 6132 can be tested separately during airtightness testing, reducing the time required to locate leaks and quickly identifying the leak point.

[0447] The piping system 600 also includes a connecting pipe 6133, through which the first pipe body 6131 and the second pipe body 6132 are detachably connected. By providing the connecting pipe 6133, one end of which is detachably connected to the first pipe body 6131 and the other end of which is detachably connected to the second pipe body 6132, the difficulty of separating the first pipe body 6131 and the second pipe body 6132 is reduced. Furthermore, by making the first pipe body 6131 and the second pipe body 6132 detachably connected through the connecting pipe 6133, the airtightness of the first pipe body 6131, the second pipe body 6132, and the connecting pipe 6133 can be tested separately during airtightness testing, reducing the time required to locate leaks and quickly identifying the leak point.

[0448] The first tube body 6131 includes a first shut-off device 710, which is configured to connect or disconnect the first tube body 6131 and the connecting pipe 6133. The second tube body 6132 includes a second shut-off device 720, which is configured to connect or disconnect the second tube body 6132 and the connecting pipe 6133. Since the energy storage system 10 requires commissioning before leaving the factory, the first tube body 6131, the connecting pipe 6133, and the second tube body 6132 already contain a first heat exchange medium. When it is necessary to disassemble the connecting pipe 6133, the first shut-off device 710 and the second shut-off device 720 can be closed first, thereby disconnecting the first tube body 6131 and the connecting pipe 6133, and disconnecting the second tube body 6132 and the connecting pipe 6133. This prevents leakage of the first heat exchange medium in the first tube body 6131 and the second tube body 6132 when disassembling the connecting pipe 6133. During assembly, the connecting pipe 6133 is first connected to the first pipe body 6131 and the second pipe body 6132. Then, the first throttling device 710 and the second throttling device 720 are opened to connect the first pipe body 6131 and the connecting pipe 6133, and the second pipe body 6132 and the connecting pipe 6133, so as to realize the circulation of the first heat exchange medium.

[0449] The connecting pipe 6133 is provided with a vent 730 and a discharge port 740, with the vent 730 positioned higher than the discharge port 740. The vent 730 is equipped with a first switch 750 configured to open or close the vent 730, and the discharge port 740 is equipped with a second switch 760 configured to open or close the discharge port 740. Before disassembling the connecting pipe 6133, it already contains a first heat exchange medium. To facilitate disassembly, the vent 730 can be opened first via the first switch 750 to balance the air pressure inside and outside the connecting pipe 6133, and then the discharge port 740 can be opened via the second switch 760 to release the first heat exchange medium from the connecting pipe 6133.

[0450] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
