Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery energy storage equipment technology, and in particular to a circuit system and an energy storage container. Background Technology
[0002] In overseas energy storage projects, there are extremely strict requirements on the weight of the storage compartments during transportation; exceeding the weight limit significantly increases transportation costs. Therefore, a modular compartment design has emerged. However, due to the modular design, each compartment is completely independent and requires its own fire detection equipment. Due to cost constraints, the signals from each compartment must be connected to the fire alarm control panel, making it impossible to completely separate the compartments from the container. To address the issue of wiring harnesses from the compartments needing to be integrated into the control panel, some manufacturers have adopted a hostless approach, allowing for independent control of each compartment. However, the main problem with hostless solutions is the inability to store data; historical data cannot be retrieved when a detector alarm occurs. As the requirements for battery cells in the energy storage field become increasingly stringent, cell capacity and weight are also increasing.
[0003] Considering overseas transportation needs, the existing 20-foot standard containers need to be redesigned as containers plus modular cabinets. In this process, the modular cabinets need to be transported separately, and the internal wiring harnesses require a convenient connector box to be designed on the bottom wall of the container for quick connection and maintenance at the terminal. However, the space at the bottom of the container is limited, making it difficult for operators to pull long wiring harnesses out of the container and into the modular cabinets for wiring. Connecting these fire protection, communication, and power lines at the project site would be too much work.
[0004] To address the above issues, a line system and an energy storage container are proposed. Utility Model Content

[0034] The following description, in conjunction with the accompanying drawings, provides a more detailed account of a line system and an energy storage container according to the present invention, illustrating preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the scope of the invention.
[0035] In the description of this specification, terms such as "one embodiment" or "some embodiments" mean that one or more embodiments of this specification include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.
[0036] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0037] In existing technologies, modular energy storage containers often face the challenge of complex wiring harness connection operations during transportation. Due to weight restrictions, energy storage systems require a modular compartment design, with each compartment needing independent fire detection equipment connected to a fire alarm control panel via wiring harnesses. Traditional wiring methods necessitate extensive on-site reconnection of wiring harnesses when transporting the compartments separately from the container, and the limited space at the bottom of the container makes this difficult. While existing hostless solutions simplify transportation, they suffer from the inability to store historical data, impacting fault analysis capabilities.
[0038] To address the aforementioned issues, the applicant, through repeated experiments, discovered that the physical layout and connection methods of the wiring harness system directly impact transportation efficiency and maintenance quality. It was recognized that a wiring harness architecture capable of supporting both modular transportation and maintaining data integrity must be constructed. Analysis of post-transport installation scenarios revealed vertical space limitations in the junction area between the modular cabinet and the container, making traditional horizontal cabling methods insufficient for rapid assembly and disassembly. Therefore, a solution was proposed that combines centralized control functions with modular wiring harness connections. This approach enables rapid wiring harness connection through standardized interfaces, while ensuring the core control device remains fixed.
[0039] Therefore, this utility model proposes a wiring system suitable for energy storage containers, and the wiring system according to an embodiment of this utility model is described below with reference to the accompanying drawings.
[0040] According to the circuit system 2 of this utility model embodiment, such as Figure 1 As shown, it includes a first wiring harness 21, a second wiring harness 22, a junction box assembly 23, and a control device (not shown). The first wiring harness 21 is installed on the support 3 of the energy storage container 100 (e.g., Figure 2As shown, the junction box assemblies 23 are mounted on the bottom wall of the bracket 3 and extend along the first direction Y, and are electrically connected to the control device. Multiple junction box assemblies 23 are mounted on the bottom wall of the bracket 3 and are electrically connected to the first wiring harness 21. (As shown) Figure 1 , Figure 7 As shown, the second wiring harness 22 is installed on the side wall of the split-type enclosure 1, electrically connected to the internal device, and connected to the junction box device 23 by a detachable plug-in method, so that the control device can realize the data collection and control functions.
[0041] The first wiring harness 21 refers to the main trunk line laid directionally along the bottom wall of the energy storage container 100, which can be implemented using multi-core cables, and is used to establish a fixed connection between the control device and each wiring node. The second wiring harness 22 refers to the branch cables connecting the internal equipment of the split cabinet, which can be implemented using flexible cables with standard plugs, facilitating separation from the main trunk line during split transportation. The junction box device 23 refers to the plug-in unit integrated on the main trunk line, which can be implemented using waterproof socket components, providing a standardized plug-in interface for the second wiring harness 22. The control device refers to a central controller with data processing capabilities, which can be implemented using an industrial PLC, used to centrally store operating data and execute control commands.
[0042] Specifically, the first wiring harness 21 is laid longitudinally along the support 3 on the bottom wall of the container to form a fixed wiring layer, permanently connecting with the control device and improving the stability of the core control network. The junction box device 23 is distributed on the first wiring harness 21 at preset intervals, forming multiple standard plug points. The second wiring harness 22 is fixed to the side wall of the split cabinet and directly connected to the internal equipment, with its end equipped with a plug that matches the junction box. During transportation, the second wiring harness 22 remains separate from the junction box, allowing the split cabinet to be transported independently; during on-site installation, the operator only needs to vertically insert the plug of the second wiring harness 22 into the bottom wall junction box to complete the control loop reconstruction. This layout avoids complex wiring operations in the narrow bottom wall space and simplifies the installation process through vertical plugging.
[0043] Compared to existing technologies, traditional solutions require re-laying a complete wiring harness from the container floor to the modular unit after transportation. This invention, however, shortens on-site installation time through pre-installed junction boxes and standardized plug-in interfaces. Existing hostless solutions suffer from data loss due to the lack of a central controller, while this invention, by retaining the fixed connection to the control device, provides historical data storage capabilities. Traditional horizontal cabling methods are difficult to implement when space is limited on the floor; this invention utilizes a vertical backbone combined with vertical plug-in designs, allowing operators to easily complete wiring operations.
[0044] Through the above technical solution, this utility model achieves rapid disassembly and reliable control of the wiring harness of the split-type energy storage container 100. During transportation, the second wiring harness 22 is separated from the junction box, meeting the independent transportation requirements of the split cabinet; during on-site installation, control functions can be restored through standardized plug-in connections, reducing wiring workload. The control device continuously stores operating data through the fixedly connected first wiring harness 21, solving the data loss problem in hostless solutions. The design of longitudinal wiring combined with vertical plug-in effectively overcomes the deficiency of insufficient operating space on the bottom wall of the container, improving operation and maintenance efficiency.
[0045] In some embodiments of this utility model, such as Figure 8 As shown, the split-type container 1 of the energy storage container 100 is provided with a clearance hole 101 on the bottom wall, and the clearance hole 101 is provided corresponding to the junction box device 23.
[0046] The clearance hole 101 refers to a pre-drilled hole in the bottom wall of the split-type enclosure 1. Specifically, it can be formed as a through hole on a metal base plate using stamping or cutting processes. The size of this hole matches the outer contour of the junction box device 23, allowing the junction box device 23 to be embedded within it. The position of the clearance hole 101 is determined based on the installation position of the junction box device 23 on the bottom wall of the bracket 3, ensuring that the hole axis coincides with the central axis of the junction box device 23.
[0047] Specifically, the clearance hole 101 on the bottom wall of the split-type enclosure 1 is positioned and opened during the manufacturing stage. When installing the junction box device 23, the operator can push the junction box device 23 upward into the predetermined position inside the split-type enclosure 1 through the clearance hole 101, and then fix the junction box device 23 to the bottom wall of the bracket 3 with bolts. Due to the correspondence between the clearance hole 101 and the junction box device 23, the mounting plane of the junction box device 23 is flush with the outer surface of the bottom wall of the split-type enclosure 1, avoiding the formation of a protruding structure. After the split cabinet is transported to the project site, the operator can directly connect the wiring harness through the exposed junction box interface of the clearance hole 101, without having to perform blind operation in the narrow space of the container bottom wall.
[0048] Compared to existing technologies, in traditional solutions, the junction box is directly exposed on the outer surface of the bottom wall of the split enclosure 1, making it susceptible to damage from external impacts during transportation. Furthermore, on-site connection operations must be completed within the limited space of the bottom wall of the split enclosure 1. This invention embeds the junction box device 23 into the bottom wall of the split enclosure 1 using the clearance hole 101 structure. This protects the structural integrity of the junction box device 23 and provides a clear connection and positioning reference for on-site operations, eliminating the risk of misoperation due to limited space.
[0049] Through the above technical solution, this utility model achieves precise positioning of the junction box when quickly connecting the split cabinet and the container. Operators can accurately identify the connection position without the need for additional positioning tools, effectively shortening the on-site wiring operation time. The embedded design of the avoidance hole 101 avoids the formation of protruding parts on the bottom wall of the split cabinet 1, ensuring that the junction box device 23 will not be displaced or damaged due to external impact during transportation, thus ensuring the stability of the system connection.
[0050] In some embodiments of this utility model, the second wiring harness 22 includes a control wiring harness (not shown) and a fire-fighting wiring harness (not shown). One end of the control wiring harness is electrically connected to the battery of the energy storage container 100, and the other end of the control wiring harness is plugged into the junction box device 23. One end of the fire-fighting wiring harness is electrically connected to the fire-fighting piping system of the energy storage container 100, and the other end of the fire-fighting wiring harness is plugged into the junction box device 23.
[0051] The control harness refers to a collection of wires used to transmit battery operation data. Specifically, it can be implemented using a multi-core cable with a waterproof connector. Its plug end can be configured as an RJ45 or aviation plug, and it can be quickly connected to the junction box through a standardized interface.
[0052] The fire protection wiring harness refers to the collection of wires connecting the fire detection device and the alarm system. Specifically, it can be implemented using flame-retardant shielded cables, and its plug-in end can be configured as a threaded locking connector to ensure the stability of fire signal transmission and prevent accidental activation.
[0053] Specifically, battery operation data is transmitted to the junction box device 23 via the control harness, and fire protection piping system status signals are synchronously transmitted to the junction box device 23 via the fire protection harness. The two types of harnesses form physically isolated communication channels with the junction box through independent plug-in interfaces. When the cabinet is separated from the container, the harnesses can be separated simply by disconnecting the plug-in interfaces. After the cabinet is transported to the project site, operators can rebuild the signal path by plugging it in, without the need for re-laying cables or tightening terminal blocks.
[0054] Compared to existing technologies, traditional solutions use a single composite cable harness to carry all signals, requiring the handling of multiple cable sets during assembly and disassembly, and posing a risk of interface confusion. This invention, however, utilizes a functionally separated cable harness design and a standardized plug-in structure to create physically isolated transmission paths for control signals and fire signals, avoiding signal crosstalk and enabling rapid separation and reassembly of separate cabinets and containers.
[0055] Through the above technical solution, this utility model realizes modular disassembly and assembly of signal connections between split cabinets and containers, shortening operation time and eliminating false alarms caused by signal cross-interference. Maintenance personnel only need to perform plugging and unplugging actions to complete the switching of wiring harness connection status, and there is no need to carry special tools or perform complex line tests during maintenance.
[0056] In some embodiments of this utility model, such as Figures 1-4 As shown, the junction box device 23 includes a first junction box 231 and a second junction box 232. The first wiring harness 21 integrates a plurality of first interfaces 2311 on the first junction box 231, and the plurality of first interfaces 2311 are electrically connected to the control wiring harness. The first wiring harness 21 integrates a plurality of second interfaces 2321 on the second junction box 232, and the plurality of second interfaces 2321 are electrically connected to the fire protection wiring harness.
[0057] The first junction box 231 refers to an independent functional module for integrating the control harness connection interface. Specifically, it can be implemented using a pluggable interface array, for example, by setting snap-on terminal blocks inside the junction box, allowing the control harness to be quickly connected via pre-set positioning slots. The second junction box 232 refers to an isolated functional unit specifically for connecting the fire protection harness. Specifically, it can be made of fire-resistant material with an internal anti-misconnection guide structure, such as irregularly shaped protrusions around the interface to prevent the fire protection harness from being mixed with the control harness. The first interface 2311 and the second interface 2321 respectively represent electrical connection nodes with different functional attributes, which can be implemented using color coding or shape differentiation design. For example, the control interface can be set as a blue rectangular terminal while the fire protection interface can be set as a red trapezoidal terminal.
[0058] Specifically, two independent units, the first junction box 231 and the second junction box 232, are arranged in parallel on the bottom wall of the support 3 on the bottom wall of the energy storage container 100. The control harness extends through the first harness 21 to multiple first interfaces 2311 integrated within the first junction box 231. Each first interface 2311 mates with the connector at the end of the control harness via a standardized plug-in method. The fire protection harness extends through the same first harness 21 to multiple second interfaces 2321 within the second junction box 232. The second interfaces 2321 employ a connection structure with directional identification characteristics, ensuring that the fire protection harness does not physically interfere with the control harness when plugged in. The first harness 21 branches into two independent cable bundles within the installation channel on the bottom wall of the support 3, respectively supplying power and signal paths to the first junction box 231 and the second junction box 232, thereby forming a parallel connection architecture for the control and fire protection systems within a limited space.
[0059] Compared to existing technologies, traditional solutions involve the control and fire protection wiring harnesses sharing a single junction box, leading to mixed interfaces and requiring operators to spend time identifying different functional interfaces. This invention achieves functional zoning by using independent junction boxes. During maintenance, the corresponding interface can be selected directly based on the box markings. For example, when inspecting the fire protection system, only the interface in the second junction box 232 needs to be operated, eliminating the need to sift through mixed wiring to find the target interface. The probability of misconnection due to wiring harness crossings in existing technologies is eliminated, and the parallel layout of the two junction boxes provides sufficient working space for operating tools.
[0060] Through the above technical solution, this utility model solves the problem of complex installation procedures caused by mixed functional wiring harnesses in the split-type energy storage container 100. Operators can quickly locate and connect the wiring harnesses based on the customized interface design. During maintenance, the control or fire protection system can be handled independently through a separate junction box, avoiding the risk of misoperation. The modular interface layout improves the efficiency of wiring harness docking during the disassembly and assembly of the split cabinet, and the physical isolation design between the fire protection wiring harness and the control wiring harness ensures the reliability of the system response in emergency situations.
[0061] In some embodiments of this utility model, such as Figures 4-6 As shown, the first junction box 231 includes a first housing 2312 and a first mounting plate 2313. The first housing 2312 is mounted on the bottom wall of the bracket 3. The housing has a first opening 2314 formed in a second direction perpendicular to the first direction. The first mounting plate 2313 is detachably mounted at the first opening 2314. A plurality of first interfaces 2311 are provided on the end face of the first mounting plate 2313 away from the first housing. The second junction box 232 includes a second housing 2322 and a second mounting plate 2323. The second housing 2322 is mounted on the bottom wall of the bracket 3. The housing has a second opening 2324 formed in a second direction perpendicular to the first direction. The second mounting plate 2323 is detachably mounted at the second opening 2324. A plurality of second interfaces 2321 are provided on the end face of the second mounting plate 2323 away from the second housing 2322.
[0062] The first housing 2312 refers to a rigid structure for fixed installation on the bottom wall of the support 3 of the energy storage container 100, and can be made of die-cast aluminum alloy. Its function is to provide a stable mounting base for the first mounting plate 2313. The first opening 2314 refers to a channel set perpendicular to the wire harness laying direction, and can be processed by stamping. Its function is to allow the mounting plate to be disassembled and assembled in the vertical direction. The first mounting plate 2313 refers to an independent functional module with an interface, and can be made of sheet metal with threaded holes. Its function is to centrally arrange the interfaces in an accessible area for easy maintenance. The second housing 2322 and the second mounting plate 2323 are similarly defined to the first housing 2312 and the first mounting plate 2313, except that they are used to arrange the fire-fighting wire harness interfaces.
[0063] Specifically, after the housing is bolted to the bottom wall of the bracket 3, the vertical openings allow the mounting plate to be installed and removed without having to penetrate deep into the container's bottom wall. The interfaces are centrally located on the outer end face of the mounting plate, allowing operators to easily connect the wiring harness by approaching from the side. The mounting plate and housing are connected by clips or screws, ensuring stability during transport and facilitating quick disconnection of the wiring harness during site maintenance. The vertical opening design of the housing fully utilizes the side space of the container's bottom wall, avoiding the space occupied by traditional horizontal openings.
[0064] Compared to existing technologies, traditional junction boxes typically employ a monolithic housing structure with interfaces located inside the housing, requiring the entire housing to be disassembled or accessed from confined spaces for maintenance. This invention, however, combines a split housing with a detachable mounting plate, allowing the interface module to be maintained independently without removing the housing. Furthermore, the vertical opening design shifts the operating direction from the bottom to the side, effectively overcoming the limitations of bottom wall space.
[0065] Through the above technical solution, this utility model can realize the quick plugging and unplugging operation of the control harness and the fire protection harness interface when the bottom wall space of the energy storage container 100 is limited. During operation and maintenance, the harness can be separated or connected simply by removing the mounting plate. There is no need to re-lay cables or disassemble the entire junction box, which significantly shortens the disassembly and assembly time of the split cabinet and the container.
[0066] In some embodiments of this utility model, such as Figure 5 , Figure 6As shown, the first junction box 231 has a first connection port 2315 at one end near the bottom wall of the bracket 3, and the first wire harness 21 passes through the first connection port 2315 to integrate the first interface 2311 on the first mounting plate 2313; the second junction box 232 has a second connection port 2325 at one end near the bottom wall of the bracket 3, and the first wire harness 21 passes through the second connection port 2325 to integrate the second interface 2321 on the second mounting plate 2323.
[0067] The first connection port 2315 refers to an opening structure located in the contact area between the bottom wall of the first junction box 231 and the bottom wall of the bracket 3. Specifically, it can be implemented using a rectangular or circular through-hole. The diameter or side length of this opening can be greater than 1.2 times the outer diameter of the wire harness, used to guide the wire harness vertically into the junction box from the bottom wall. The second connection port 2325 is implemented in the same way as the first connection port 2315, and its position corresponds to the contact surface between the second junction box 232 and the bottom wall of the bracket 3. The first mounting plate 2313 refers to a detachable metal or plastic plate covering the opening of the first junction box 231. Its surface can be provided with a snap-on or threaded fixing structure for integrating multiple control line interfaces. The structure of the second mounting plate 2323 is symmetrical to that of the first mounting plate 2313, the difference being that its integrated interface type is a fire alarm line interface.
[0068] Specifically, during installation, the first wiring harness 21 is laid along the bottom wall of the bracket 3, then vertically upwards through the first connection port 2315 into the first junction box 231, where the control line interface is integrated on the end face of the first mounting plate 2313. The second wiring harness 22 enters the second junction box 232 through the second connection port 2325 in the same manner, and the fire protection line interface is integrated on the end face of the second mounting plate 2323. Operators do not need to enter the narrow space at the bottom of the container when wiring; they only need to remove the mounting plate to directly access the interface and complete the connection. The vertical insertion path of the wiring harness avoids horizontal bending and tangling, and the centralized arrangement of the interfaces allows for quick disconnection when the split cabinet is separated from the container.
[0069] Compared to existing technologies, traditional solutions typically place the wiring harness entry point of the junction box on the side, requiring the wiring harness to pass horizontally into the junction box and occupying bottom wall space. Operators must then enter the narrow bottom wall area to perform wiring. In contrast, this invention allows the wiring harness to pass vertically through the bottom wall connection port. Combined with the detachable design of the mounting plate, the interfaces are centrally located on the operating surface. This means that when the split cabinet is separated from the container, only the plug-in interface on the mounting plate needs to be disconnected, without needing to rearrange the bottom wall wiring harness.
[0070] Through the above technical solution, this utility model solves the problem of difficult wiring harness installation caused by insufficient operating space on the bottom wall of the split-type energy storage container 100, realizes independent and quick plug-in of the fire protection wiring harness and the control wiring harness, and enables the split cabinet and container to be quickly reassembled on the project site after separate transportation. During operation and maintenance, the mounting plate can be directly disassembled for interface maintenance without replacing the entire wiring harness or rewiring.
[0071] In some embodiments of this utility model, a protective tube is also included, in which the first wire harness 21 and the second wire harness 22 pass through the protective tube.
[0072] The protective tube refers to a conduit structure used to wrap the wire harness. Specifically, it can be implemented using a corrugated metal pipe. Its corrugated structure allows for bending to accommodate the wire harness's routing, while also providing fire resistance and waterproof sealing. This structure physically isolates and wraps the wire harness, preventing damage to the cable sheath from transport vibrations or foreign objects, while also constraining the wire harness's routing to reduce the complexity of path planning during installation.
[0073] The term "threading" refers to passing the wire harness through the inside of the protective tube. This can be achieved by pre-threading the wire harness into the tube cavity and then fixing the two ends. This operation creates an integrated structure between the wire harness and the protective tube, avoiding redundant disassembly and assembly movements caused by the wire harness being scattered, and ensuring that the wire harness can move as a whole when the split cabinet and container are quickly connected.
[0074] Specifically, the first wire harness 21 and the second wire harness 22 are independently threaded within the protective tube, forming two parallel protective channels. The metal corrugated tube wraps around the wire harness and is fixed to the support 3 on the bottom wall of the container. The flexible nature of the corrugated tube accommodates the bending requirements of the wire harness within a limited space. Both ends of the protective tube extend to the interface between the junction box device 23 and the split cabinet. During maintenance, the entire protective tube can be pulled out from the bottom wall of the container and connected to the split cabinet interface to complete the wire harness connection, without needing to adjust the position of each wire harness individually. During split-unit transportation, the protective tube and wire harness move as a single unit with the split cabinet, avoiding the wear risk caused by disassembling the wire harness individually.
[0075] Compared to existing technologies, current solutions lack the protective tube, leaving the wire harness directly exposed to the container's bottom wall. This makes the harness susceptible to damage during transport due to vibrations, which can cause the sheath to crack or the connections to loosen. Furthermore, the messy arrangement of the wire harness necessitates individual disassembly and reassembly, resulting in low operational efficiency. This invention integrates and fixes the wire harness into a modular structure using the protective tube, reducing the probability of transport damage and minimizing the number of steps required for installing and maintaining individual wire harnesses.
[0076] In some embodiments of this utility model, a first limiting part is provided on the bottom wall of the bracket 3. The first limiting part extends along the first direction and is located at an edge of the bottom wall of the bracket 3. An installation channel is provided in the first limiting part along the first direction, and the first wire harness 21 is laid in the installation channel.
[0077] The first limiting part refers to the guide structure set at the edge of the bottom wall of the bracket 3. Specifically, it can be implemented by welding or bolting a metal profile with a U-shaped or C-shaped cross-section. It extends along the length of the bracket 3 to form a continuous guide groove, which is used to establish a wire harness fixing channel in the edge area of the container bottom wall. The mounting channel refers to the through cavity opened along the length of the first limiting part. Specifically, it can be implemented by pre-reserving through holes in the profile or by forming a closed pipe by splicing plates. It is used to constrain the direction of the wire harness and prevent the wire harness from coming off due to transportation vibration.
[0078] Specifically, the first limiting part is located at the edge of the bottom wall of the bracket 3, utilizing the unoccupied edge space of the container's bottom wall to establish a wiring harness fixing channel, avoiding spatial conflicts with the central equipment installation area. The mounting channel runs through the container in the first direction, allowing the wiring harness to extend from one end of the container to the other, forming a predetermined wiring path. When the wiring harness is laid within the mounting channel, its direction is physically constrained by the inner wall of the channel, preventing lateral shifting or axial movement during transportation. When the split cabinet is separated from the container, the connectors at both ends of the wiring harness remain at the ports of the mounting channel, allowing for quick docking without the need to rearrange the wiring harness.
[0079] Compared to existing technologies, traditional methods of directly laying wire harnesses on the bottom wall of containers lack a fixing structure, making the wire harnesses prone to displacement and entanglement during transportation, and requiring a large amount of operating space for on-site wiring. This utility model, through a guide structure set at the edge and an internal conduit, achieves pre-positioned installation of the wire harness within a limited space, eliminating the need for wire harness maintenance and avoiding occupying operating space in the equipment installation area.
[0080] Through the above technical solution, this utility model realizes the directional fixation and rapid assembly / disassembly of wire harnesses in confined spaces. The wire harnesses maintain a stable direction during transportation. When the split cabinet is separated from the container, the connection operation can be completed directly through the pipe port, which effectively reduces the amount of on-site wiring work and improves the efficiency of equipment assembly / disassembly.
[0081] This utility model also provides an energy storage container 100, which includes the above-described line system 2.
[0082] The base wall of the support frame 3 refers to the base frame supporting the main structure of the energy storage container 100. It can be constructed using welded or bolted metal profiles and is used to support the wiring harness and the junction box device 23. The junction box device 23 is a modular connection unit integrating electrical interfaces. It can be constructed using a combination of an injection-molded housing and a detachable mounting plate, used to centrally arrange plug-in interfaces and enable quick assembly and disassembly. The first wiring harness 21 refers to the main line extending along the base wall of the support frame 3. It can be constructed using a combination of a multi-core cable and the protective conduit, used to provide power supply and signal transmission channels for the split cabinet. The second wiring harness 22 refers to the branch line connecting to the internal devices of the split cabinet. It can be constructed using a flexible cable with a plug, used to transmit fire and control signals from the split cabinet to the junction box device 23.
[0083] Specifically, the first wiring harness 21 is laid along the mounting holes on the bottom wall of the bracket 3, and its direction is fixed by a limiting part to prevent the wiring harness from shifting due to transportation vibration. The junction box device 23 is fixed to the edge of the bottom wall of the bracket 3 by the housing, and its mounting plate is set perpendicular to the extension direction of the wiring harness, so that the interface faces the external operating space. The second wiring harness 22 is pre-connected to the internal device of the split cabinet. The split cabinet is separated from the container during transportation. During on-site installation, only the plug of the second wiring harness 22 needs to be aligned with the interface of the junction box device 23 and inserted. The control device receives and stores real-time data from the split cabinet through the first wiring harness 21, and at the same time sends control commands to the fire protection or battery management module.
[0084] Compared to existing technologies, the current split-type energy storage container 100 requires rewiring and manual connection after transportation, resulting in low efficiency due to limited operating space. This invention, through the pre-installed standardized interface junction box device 23, allows the split cabinet wiring harness to be pre-connected before transportation. On-site, signal transmission can be restored simply by plugging and unplugging, without the need for rewiring or re-threading. Simultaneously, the limiting structure of the first wiring harness 21 and the design of the protective tube prevent wear or detachment of the wiring harness during transportation, ensuring connection stability.
[0085] Through the above technical solution, this utility model achieves rapid separation and reconnection of the wiring harness between the split cabinet and the container, reducing tedious procedures such as wire threading, stripping, and crimping terminals during on-site installation, and solving the problem of low wiring efficiency caused by narrow bottom wall space. The modular interface layout of the junction box device 23 allows maintenance personnel to complete plugging and unplugging operations without entering the bottom wall of the container, reducing operational difficulty. The pre-connected wiring harness design also avoids poor contact or polarity errors that may occur with manual wiring, improving system reliability.
