Description

Technical Field

[0001] This invention relates to the field of energy storage container technology, and more specifically to a modular energy storage container. Background Technology

[0002] With the rapid development of the power storage market, end-customers' demand for the capacity of energy storage battery container systems is increasing, which directly leads to a significant increase in the system's weight. Currently, a standard 20-foot energy storage container system generally weighs over 35 tons. This weight makes it difficult to transport the system as a whole in mountainous areas, remote regions, and countries and regions with strict road weight restrictions, severely restricting the deployment and application of highly integrated energy storage solutions in these markets.

[0003] To address this challenge, related technical solutions are often forced to abandon containerized systems and instead adopt distributed configurations with lower energy density, such as standard battery packs or commercial outdoor cabinets. However, such solutions have significant drawbacks: their system integration is low, requiring numerous electrical series and parallel connections when assembling a power plant, resulting in numerous interfaces, complex system structures, and difficulty in achieving simple and efficient centralized operation and maintenance management. Summary of the Invention

[0004] The embodiments of the present invention provide an energy storage container that can improve the problems of low system integration, numerous interfaces, complex system structure, and difficulty in achieving simple and efficient centralized operation and maintenance management in related technologies.

[0005] An embodiment of the present invention provides an energy storage container, comprising: a container body, having a liquid cooling compartment and multiple cabinet compartments; a liquid cooling unit disposed within the liquid cooling compartment; multiple battery cabinets, each battery cabinet being detachably installed within a cabinet compartment, each battery cabinet having a first circuit interface and a liquid cooling interface, the first circuit interface being used for electrical connection with the main circuit of the container body; and liquid cooling pipelines disposed within the container body, one end of the liquid cooling pipelines being connected to the liquid cooling unit, and the other end being connected to the liquid cooling interface.

[0006] In one embodiment, the battery cabinet includes a cabinet body, a high-voltage box, and multiple battery packs. The high-voltage box and multiple battery packs are disposed inside the cabinet body, and all battery packs are electrically connected to the high-voltage box. A first circuit interface is installed in the cabinet body, and the high-voltage box is electrically connected to the first circuit interface and to the main circuit of the cabinet body through the first circuit interface.

[0007] Installing the first circuit interface on the cabinet makes the structure more integrated and facilitates simultaneous connection with the main circuit of both the high-voltage box and the cabinet. In one embodiment, both the first circuit interface and the liquid cooling interface are located at the bottom of the cabinet on the side near the cabinet door.

[0008] The first circuit interface and liquid cooling interface are located in the cabinet, which helps with structural integration and facilitates the assembly of the energy storage container.

[0009] In one embodiment, the battery cabinet includes a cabinet body, a high-voltage box, and multiple battery packs. The high-voltage box and multiple battery packs are disposed inside the cabinet body, and all battery packs are electrically connected to the high-voltage box. A first circuit interface is disposed in the high-voltage box, and the first circuit interface is electrically connected to the main circuit of the cabinet body through an output main wire.

[0010] By setting the first circuit interface on the high-voltage box, the battery cabinet can be connected to the main circuit of the container through the output main wire when assembling the energy storage container, which is simple and convenient to operate.

[0011] In one embodiment, the bottom of the cabinet is provided with a wire through hole and a liquid cooling pipe through hole, and both the wire through hole and the liquid cooling pipe through hole are located on the side of the bottom of the cabinet near the cabinet door. The wire through hole is used for the main output wire to pass through, and the liquid cooling pipe through hole is used for the pipe connecting the liquid cooling interface and the liquid cooling pipe to pass through.

[0012] By uniformly setting the wire through holes and liquid cooling pipelines at the bottom of the same side of the cabinet, it not only facilitates assembly by assembly personnel, but also contributes to the integration of energy storage containers.

[0013] In one embodiment, the main circuit of the enclosure includes multiple second circuit interfaces, which are located at the bottom of the enclosure, with the high-voltage box positioned near the bottom of the enclosure; when the battery cabinet is installed, the second circuit interfaces can be electrically connected to the first circuit interface via the main output wire.

[0014] Placing the high-voltage box at the bottom of the cabinet facilitates the connection between the first circuit interface and the second circuit interface of the main circuit at the bottom of the cabinet, shortening cable routing and making the overall device simpler.

[0015] In one embodiment, a first bracket is provided inside the cabinet. The first bracket is provided with a high-voltage box mounting position and multiple battery pack mounting positions. The multiple battery pack mounting positions are arranged from top to bottom, and the high-voltage box mounting position is located at the bottom of the first bracket. The high-voltage box is located at the high-voltage box mounting position, and the battery packs are located at the battery pack mounting positions.

[0016] The first bracket allows the battery pack and high-voltage box to be installed more neatly inside the cabinet.

[0017] In one embodiment, the liquid cooling pipeline includes a first liquid cooling pipe and multiple sets of second liquid cooling pipes. The first liquid cooling pipe is at least partially disposed between the bottom of the cabinet compartment and the bottom of the enclosure, and one end of the first liquid cooling pipe is connected to the liquid cooling unit. Multiple sets of second liquid cooling pipes are disposed between the bottom of the cabinet compartment and the bottom of the enclosure, and the multiple sets of second liquid cooling pipes are configured one-to-one with multiple cabinet compartments. One end of each set of second liquid cooling pipes is connected to the first liquid cooling pipe, and the other end is connected to the liquid cooling interface through a fluid connector.

[0018] Both the first and second liquid cooling pipes are located between the bottom of the cabinet compartment and the bottom of the container, which allows the coolant in the energy storage container to enter and exit from the bottom, thus reducing the amount of pipe used.

[0019] In one embodiment, the first liquid cooling pipe includes a primary input pipe and a primary output pipe, and the second liquid cooling pipe includes a secondary input pipe and a secondary output pipe. The two ends of the secondary input pipe are respectively connected to the primary input pipe and the liquid cooling interface of the battery cabinet inlet to input coolant into the battery cabinet. The two ends of the secondary output pipe are respectively connected to the primary output pipe and the liquid cooling interface of the battery cabinet outlet to output the coolant returning from the battery cabinet to the liquid cooling unit. By connecting the primary input pipe, the secondary input pipe, and the liquid cooling interface at the battery cabinet inlet, as well as the liquid cooling interface at the battery cabinet outlet, the secondary output pipe, the primary output pipe, and the liquid cooling unit, the battery cabinet can be circulated for cooling, ensuring battery safety.

[0020] In one embodiment, the bottom of the enclosure is provided with multiple sets of second supports, and each battery cabinet can be detachably installed on one set of second supports; each set of second supports includes two second supports spaced apart, and the two second supports in the same set have a receiving space, the first liquid cooling pipe passes through the multiple sets of second supports and is partially disposed in the receiving space; the second liquid cooling pipe is disposed in the receiving space and is connected to the first liquid cooling pipe disposed in the receiving space.

[0021] The second bracket can simultaneously install the battery cabinet and the first liquid cooling pipe, which helps to simplify the device. In addition, there is a space between the second brackets in the same group to accommodate the second liquid cooling pipe, which can save space.

[0022] The beneficial effects of embodiments of the present invention: This application provides a modular energy storage container. By adopting a design of "setting multiple cabinet compartments in the container body" and configuring "each battery cabinet to be detachably installed in one cabinet compartment", the traditional integrated container is decomposed into multiple units that can be transported in a decentralized manner, which can solve the problem that the whole container is too heavy to be transported to areas with weight restrictions. At the same time, each battery cabinet is provided with a first circuit interface and a liquid cooling interface. The first circuit interface is detachably electrically connected to the main circuit of the container body, and the liquid cooling interface is detachably connected to the liquid cooling pipeline, which enables quick assembly and disassembly from the container body. This makes on-site installation as simple and efficient as building blocks. It retains the advantages of centralized system high integration and easy unified management, while improving the problems of complicated on-site wiring and operation and maintenance of traditional decentralized solutions, and achieves a unity of transportation flexibility and operation and maintenance efficiency.

Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0026] This application provides a modular energy storage container; please refer to [reference needed]. Figure 1-6 The energy storage container 100 includes a container body 110, a liquid cooling unit 120, multiple battery cabinets 130, and liquid cooling pipelines 140.

[0027] The enclosure 110 includes a liquid cooling chamber 111 and multiple cabinet compartments 112. A liquid cooling unit 120 is housed within the liquid cooling chamber 111. Each battery cabinet 130 is detachably installed within a cabinet compartment 112. Each battery cabinet 130 is equipped with a first circuit interface 1341 and a liquid cooling interface (not shown). The first circuit interface 1341 is used for electrical connection to the main circuit 113 of the enclosure 110. A liquid cooling pipeline 140 is installed in the enclosure 110, with one end connected to the liquid cooling unit 120 and the other end connected to the liquid cooling interface.

[0028] By detachably installing the battery cabinet 130 within the cabinet compartment 112, the traditional integrated container is broken down into multiple standardized units that can be transported independently. This solves the practical problem that the entire container, due to its large size and concentrated weight, cannot be transported to areas with strict road weight restrictions or weak infrastructure. This design not only achieves physical decomposition but also enables rapid reconfiguration of functional connections through interface standardization. Each battery cabinet 130 is equipped with a standardized first circuit interface 1341 and a liquid cooling interface. The first circuit interface 1341 is detachably plugged into the main circuit 113 pre-installed within the container 110, while the liquid cooling interface is detachably and sealed to the liquid cooling pipeline 140. The collaborative design of these two types of interfaces enables true "plug-and-play" functionality between the battery cabinet 130 and the container 110. This interface-based connection method makes the on-site installation process as intuitive and simple as building blocks, greatly improving deployment efficiency. It not only fully retains the inherent advantages of centralized energy storage systems, such as high integration, high energy density, and easy unified monitoring and management, but also solves the operation and maintenance pain points of traditional distributed solutions, such as complicated on-site wiring procedures, chaotic cable management, and installation quality depending on the skill level of personnel, through modular interface technology. Ultimately, it achieves a balance between flexibility in the transportation phase and efficiency in the operation and maintenance phase at the engineering level.

[0029] In one typical embodiment of this application, such as Figure 1 As shown, the liquid cooling compartment 111 and multiple cabinet compartments 112 are arranged in two rows, with only one liquid cooling compartment 111, and the liquid cooling compartment 111 is arranged in... Figure 1 The far right of the viewpoint.

[0030] In some embodiments of this application, the battery cabinet 130 includes a cabinet 131, a high-voltage box 134, and a plurality of battery packs 135. The high-voltage box 134 and the plurality of battery packs 135 are disposed inside the cabinet 131, and all battery packs 135 are electrically connected to the high-voltage box 134. A first circuit interface 1341 is installed on the cabinet 131, and the high-voltage box 134 is electrically connected to the first circuit interface 1341 and electrically connected to the main circuit 113 of the cabinet 110 through the first circuit interface 1341.

[0031] The design of directly mounting the first circuit interface 1341 onto the cabinet 131 significantly advances the integration process of the system structure. This layout makes the interface itself an integral part of the cabinet 131, ensuring both structural integrity and compactness while creating superior conditions for connection operations. Thanks to this highly integrated design, the first circuit interface 1341 can efficiently connect to both the high-voltage box 134 and the main circuit 113 of the enclosure 110 simultaneously, completing dual connection tasks without the need for additional adapters or transition devices. This not only simplifies the system topology but also makes the synchronous connection process smooth and reliable, improving the integration of installation and maintenance and operational convenience.

[0032] In some embodiments of this application, the first circuit interface 1341 and the liquid cooling interface are both located at the bottom of the cabinet 131 on the side near the cabinet door.

[0033] By integrating the first circuit interface 1341 and the liquid cooling interface into the cabinet 131, the compactness and integration of the overall system structure are effectively advanced. This layout allows the two major functional modules of electrical connection and fluid transmission to be highly concentrated in space, which not only optimizes the space utilization efficiency inside the cabinet 131 but also improves the coordination and consistency of external connections. Thanks to this integrated interface configuration, the energy storage container 100 no longer requires separate and independent alignment and connection operations for the circuit and liquid cooling pipeline 140 during on-site assembly, thus simplifying the assembly process and reducing the complexity and time consumption of the assembly steps.

[0034] In some embodiments of this application, such as Figure 3-4 As shown, the battery cabinet 130 includes a cabinet body 131, a high-voltage box 134, and multiple battery packs 135. The high-voltage box 134 and multiple battery packs 135 are disposed inside the cabinet body 131, and all battery packs 135 are electrically connected to the high-voltage box 134. The first circuit interface 1341 is disposed in the high-voltage box 134, and the first circuit interface 1341 is electrically connected to the main circuit 113 of the cabinet body 110 through the output main wire.

[0035] The architecture design that integrates the first circuit interface 1341 onto the high-voltage box 134 simplifies the overall assembly process of the energy storage container 100. In this optimized layout, operators can establish an electrical connection path between the battery cabinet 130 and the main circuit 113 of the enclosure 110 using the main output cable as a key component. This connection method eliminates the multi-level, dispersed wiring steps that may exist in traditional solutions, consolidating the complex electrical interconnection process into a one-step direct connection operation. This not only reduces the complexity and technical requirements of docking but also improves the reliability and consistency of the connection action, making the on-site installation of the entire energy storage system smoother, more intuitive, and more time-saving and labor-saving.

[0036] In some typical embodiments of this application, the multiple battery packs 135 can be connected in series or in parallel, depending on actual needs, and no specific limitation is made. The battery packs 135 are connected in series or in parallel via power lines. In some embodiments of this application, such as Figure 6The bottom of the cabinet 131 is provided with a wire through hole 132 and a liquid cooling pipe through hole 133, and both the wire through hole 132 and the liquid cooling pipe through hole 133 are located on the bottom of the cabinet 131 near the cabinet door. The wire through hole 132 is used for the main output wire to pass through, and the liquid cooling pipe through hole 133 is used for the pipe connecting the liquid cooling interface and the liquid cooling pipe 140 to pass through.

[0037] By unifying the spatial layout of the wiring through-holes 132 and liquid cooling pipes 140 and centrally placing them on the bottom side of the cabinet 131 near the cabinet door, this design optimizes the assembly process and structural form of the energy storage container 100. For on-site assembly personnel, the centralized layout of all connection elements eliminates the need for repeated adjustments between different positions and for different height interfaces. This allows them to efficiently and continuously complete the laying and connection of all wiring and pipes in a relatively fixed and comfortable workstation, reducing operational complexity and improving the overall efficiency and accuracy of the installation work. Furthermore, this design, which concentrates key channels on a single bottom side, avoids the space waste and potential interference caused by the crossing and meandering of pipelines within the container 110, and creates a clear, orderly, and standardized internal layout. This layout allows multiple cabinets 131 to present a highly unified and orderly overall structure when combined into the complete energy storage container 100, enhancing the system's integration and facilitating subsequent maintenance, upgrades, and large-scale expansion.

[0038] like Figure 6 As shown, the liquid cooling pipe through-hole 133 includes a liquid cooling pipe inlet through-hole 1331 and a liquid cooling pipe outlet through-hole 1332. The wire through-hole 132 includes a power line through-hole 1321 and a communication line through-hole 1322.

[0039] The liquid cooling pipe inlet hole 1331 is for the pipe connecting the liquid inlet of the battery cabinet 130 and the liquid inlet of the liquid cooling pipe 140 to pass through, and the liquid cooling pipe outlet hole 1332 is for the pipe connecting the liquid outlet of the battery cabinet 130 and the liquid outlet of the liquid cooling pipe 140 to pass through.

[0040] The first circuit interface 1341 includes a first power interface and a first communication interface. The main output cable includes a power bus and a communication bus. The power bus passes through the power cable through-hole 1321, with one end connected to the first power interface and the other end electrically connected to the second power interface of the main circuit 113 of the enclosure 110. A communication line is also provided inside the battery cabinet 130. The communication line is connected in parallel with all battery packs 135, and the communication line collects the communication signals of all battery packs 135 to the high-voltage box 134, forming an independent communication network. The communication bus passes through the communication cable through-hole 1322, with one end connected to the first communication interface of the high-voltage box 134 and the other end electrically connected to the second communication interface of the main circuit 113 of the enclosure 110.

[0041] In some embodiments of this application, such as Figure 4 The main circuit 113 of the enclosure 110 includes multiple second circuit interfaces 150, which are located at the bottom of the enclosure 110. The high-voltage box 134 is located near the bottom of the cabinet 131. When the battery cabinet 130 is installed, the second circuit interfaces 150 can be electrically connected to the first circuit interface 1341 via the main output cable. It is understood that since each battery cabinet 130 in this application is independently connected to the main circuit 113 of the enclosure 110, each cabinet compartment 112 has a corresponding second circuit interface 150 at its bottom position within the enclosure 110.

[0042] It should be noted that the second circuit interface 150 includes a second power interface and a second communication interface.

[0043] By placing the high-voltage box 134 close to the bottom of the cabinet 131, this optimized layout allows the first circuit interface 1341 to be spatially aligned with the second circuit interface 150 of the main circuit 113 at the bottom of the cabinet 110. This vertically aligned interface arrangement facilitates electrical connection between the two, eliminating the need for long-distance cable detours or complex routing, thus enabling a shorter connection path. This design shortens the required cable routing distance, reducing not only the amount and cost of cables but also effectively minimizing power loss and electromagnetic interference that may result from excessively long lines.

[0044] In some embodiments of this application, such as Figure 3 The cabinet 131 is equipped with a first bracket 136. The first bracket 136 is equipped with a high voltage box mounting position 1361 and multiple battery pack mounting positions 1362. The multiple battery pack mounting positions 1362 are arranged from top to bottom, and the high voltage box mounting position 1361 is located at the bottom of the first bracket 136. The high voltage box 134 is located at the high voltage box mounting position 1361, and the battery pack 135 is located at the battery pack mounting position 1362.

[0045] By introducing the key structural component, the first bracket 136, the installation layout of the battery pack 135 and the high-voltage box 134 within the battery cabinet 130 is significantly standardized and ordered. The first bracket 136, serving as a pre-set installation reference, provides precise and stable positioning support for the battery pack 135 and the high-voltage box 134, ensuring that they are fixed within the specific space of the battery cabinet 130 according to the preset orientation and spacing. This directional installation method effectively avoids random placement or misalignment of components within the cabinet 131, allowing components that might otherwise be scattered or intertwined to present a neat and uniform spatial arrangement. Its direct effect is not only to optimize the utilization efficiency of the limited space within the battery cabinet 130 and eliminate structural interference or safety hazards that might result from a chaotic layout, but also to create an orderly and hierarchical internal structure, thereby improving the overall standardization, professionalism, and reliability of the internal organization of the battery cabinet 130.

[0046] In some embodiments of this application, such as Figure 4-5 The liquid cooling pipeline 140 includes a first liquid cooling pipe 141 and multiple sets of second liquid cooling pipes 142. The first liquid cooling pipe 141 is at least partially disposed between the bottom of the cabinet compartment 112 and the bottom of the enclosure 110, and one end of the first liquid cooling pipe 141 is connected to the liquid cooling unit 120. Multiple sets of second liquid cooling pipes 142 are disposed between the bottom of the cabinet compartment 112 and the bottom of the enclosure 110, and the multiple sets of second liquid cooling pipes 142 are configured one-to-one with multiple cabinet compartments 112. One end of each set of second liquid cooling pipes 142 is connected to the first liquid cooling pipe 141, and the other end is connected to the liquid cooling interface through a fluid connector.

[0047] Specifically, such as Figure 5 As shown, in a typical embodiment of this application, there are two first liquid cooling pipes 141, which are arranged in parallel between the bottom of the cabinet compartment 112 and the bottom of the enclosure 110. One end of each of the two first liquid cooling pipes 141 is connected to the liquid cooling unit 120. The second liquid cooling pipe 142 is arranged perpendicular to the first liquid cooling pipe 141 and is connected to the first liquid cooling pipe 141. The second liquid cooling pipe 142 has a bending structure, which is arranged on one side facing the cabinet compartment 112. When assembling the battery cabinet 130, the bending structure is quickly connected to the liquid cooling interface of the battery cabinet 130 through a fluid connector. The fluid connector is a quick plug, which can realize quick installation and disassembly.

[0048] By arranging the first liquid cooling pipe 141 and the second liquid cooling pipe 142 together in a unified space between the bottom of the cabinet compartment 112 and the bottom of the container 110, a structural foundation is laid for realizing the "bottom-in, bottom-out" mode of overall coolant circulation in the energy storage container 100. This pipe layout ensures that the inflow and outflow of the cooling medium are completed at the bottom of the system, forming a highly efficient circulation path. Compared to arrangements that require back-and-forth connections at different heights, this planar, short-path pipe design reduces the overall laying length of the pipes, effectively reducing material consumption. At the same time, the simplified pipe network not only reduces the number of connection points and improves the system's sealing reliability, but also makes the pipe routing clearer and more direct, avoiding unnecessary detours and bends, thus optimizing overall material utilization efficiency and system economy.

[0049] In some embodiments of this application, such as Figure 5 The first liquid cooling pipe 141 includes a primary input pipe 1411 and a primary output pipe 1412. The second liquid cooling pipe 142 includes a secondary input pipe 1421 and a secondary output pipe 1422. The two ends of the secondary input pipe 1421 are respectively connected to the primary input pipe 1411 and the liquid cooling interface of the battery cabinet 130 inlet to input coolant into the battery cabinet 130. The two ends of the secondary output pipe 1422 are respectively connected to the primary output pipe 1412 and the liquid cooling interface of the battery cabinet 130 outlet to output the coolant returning from the battery cabinet 130 to the liquid cooling unit 120.

[0050] By sequentially connecting the primary input pipe 1411, the secondary input pipe 1421, and the liquid inlet of the battery cabinet 130, a cooling medium transport path is formed. Simultaneously, the liquid outlet of the battery cabinet 130, the secondary output pipe 1422, the primary output pipe 1412, and the liquid cooling unit 120 are connected to form a return flow channel, collectively constructing a complete circulating refrigeration system. This system, through the continuous flow of the cooling medium, continuously transfers the heat generated by the operation of the battery cabinet 130 to the external liquid cooling unit 120 for heat dissipation, thereby ensuring that the battery remains within a safe operating temperature range and effectively guaranteeing its operational safety.

[0051] It is understood that, in a typical embodiment of this application, a common first liquid cooling channel (not shown) and a second liquid cooling channel (not shown) are also provided in the cabinet 131. One end of the first liquid cooling channel is the liquid inlet of the battery cabinet 130, which is connected to one of the liquid cooling interfaces to deliver coolant to each battery pack 135. One end of the second liquid cooling channel is the liquid outlet of the battery cabinet 130, which is connected to another liquid cooling interface to collect the coolant flowing out of the battery pack 135 and circulate the coolant to the liquid cooling unit 120.

[0052] In some embodiments of this application, such as Figure 4-5The bottom of the enclosure 110 is provided with multiple sets of second supports 114, and each battery cabinet 130 is detachably installed on one set of second supports 114. Each set of second supports 114 includes two second supports 114 spaced apart, and the two second supports 114 in the same set have a receiving space 115. The first liquid cooling pipe 141 passes through the multiple sets of second supports 114 and is partially disposed in the receiving space 115; the second liquid cooling pipe 142 is disposed in the receiving space 115 and connected to the first liquid cooling pipe 141 disposed in the receiving space 115.

[0053] In one typical embodiment of this application, the battery cabinet 130 is fixed to the second bracket 114 by bolts.

[0054] Through the integrated design of the second bracket 114, this component can simultaneously undertake the dual installation functions of supporting the battery cabinet 130 and fixing the first liquid cooling pipe 141. This dual-purpose design concept effectively reduces the number of independent installation components within the device, thereby simplifying the structure and improving the overall coordination and compactness. Furthermore, between the various second brackets 114 in the same group, regular accommodating spaces 115 specifically for laying the second liquid cooling pipe 142 are pre-planned and set. This reserved design allows the second liquid cooling pipe 142 to be orderly integrated and hidden within the frame structure formed by the brackets, avoiding the second liquid cooling pipe 142 occupying additional volume inside the device or interfering with the space of other components. Ultimately, while ensuring the integrity of the system function, the efficient utilization and optimization of the internal space of the device are achieved.
