Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a combiner box, a mobile integrated energy storage cabin, and a mobile energy storage vehicle. Background Technology

[0002] With the rapid development and widespread application of energy storage products, their application scenarios have become increasingly diversified, resulting in small-scale household energy storage needed by families, medium-sized industrial and commercial energy storage needed by factories, and large-scale energy storage needed by power plants.

[0003] Current energy storage devices are mainly stationary devices designed for specific locations. These stationary devices cannot meet temporary power demands, such as those for construction sites, highways, and mines. Therefore, mobile integrated energy storage units are needed to meet the requirements of these scenarios.

[0004] However, in existing combiner boxes, the return cabinet is too large because factors such as cabinet size and line safety do not need to be considered, making it impossible for existing combiner boxes to meet the requirements of mobile energy storage integrated modules. Utility Model Content

[0005] The purpose of this utility model is to provide a junction box that can adapt to and optimize the wiring of the mobile energy storage integrated compartment, and reduce the size of the cabinet while meeting the requirements of line safety.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a combiner box is provided for connecting a battery pack. The combiner box includes: a mounting frame forming multiple mounting spaces, with both longitudinal sides of the mounting spaces open; multiple shelves arranged vertically in the mounting spaces; and multiple connecting components, one of which is installed within a shelf and is used to connect batteries in the battery pack. Each connecting component includes an input busbar, an output busbar, and a fuse electrically connected between the input busbar and the output busbar. The input busbar and the output busbar are respectively installed on both sides of the shelf in the longitudinal direction, allowing external cables to extend into the mounting space from the open side and connect to the input busbar or the output busbar. The fuse is installed on the shelf and located between the input busbar and the output busbar. The projections of the input busbars on the multiple shelves in the same horizontal plane are staggered in the longitudinal direction, and the projections of the output busbars on the multiple shelves in the same horizontal plane are staggered in the longitudinal direction. The mounting surfaces of the input busbars and the output busbars face vertically.

[0008] In one embodiment of this application, the communication component includes two input busbars, two output busbars, and two fuses. The two input busbars are spaced apart in the lateral direction and are respectively connected to the two poles of the battery. The two output busbars are spaced apart in the lateral direction, and the two fuses are spaced apart in the lateral direction. The input busbars, the fuses, and the output busbars are arranged in a one-to-one correspondence.

[0009] In one embodiment of this application, a plurality of the mounting spaces are arranged side by side along the transverse side of the mounting frame.

[0010] In one embodiment of this application, both the input busbar and the output busbar are provided with a plurality of mounting holes for connecting external cables and the fuse. The plurality of mounting holes on the input busbar are spaced apart along their own length direction, and the plurality of mounting holes on the output busbar are spaced apart along their own length direction.

[0011] In one embodiment of this application, both the input busbar and the output busbar are connected to the shelf via an insulating element.

[0012] In one embodiment of this application, the communication component further includes a connector, the connector including a first connecting portion for connecting the fuse and a second connecting portion for connecting the input busbar or the output busbar, the first connecting portion and the second connecting portion being connected sequentially and arranged at an included angle, the second connecting portion having a mounting hole for connecting the insulating member, so that the connector can be fixed on the shelf by the insulating member.

[0013] In one embodiment of this application, the mounting frame includes a support beam, a fixed beam, a connecting beam, a mounting beam, and an auxiliary beam. The support beam extends vertically, the fixed beam extends longitudinally and is connected to the support beam, the connecting beam extends laterally and is connected to the support beam, and the mounting beam extends laterally and is connected to the fixed beam, such that the mounting beam and the fixed beam form the shelf. The mounting beam is used to mount the input cable busbar or the output cable busbar. The auxiliary beam extends laterally and is connected to the fixed beam. The auxiliary beam and the mounting beam are spaced apart longitudinally so that the auxiliary beam can support external cables.

[0014] In one embodiment of this application, the mounting frame is provided with a base plate, a box plate, and a cover plate. The base plate is connected to the mounting frame and located at the bottom of the mounting space. The box plate is connected to both ends of the mounting frame in the lateral direction. The cover plate is detachably connected to the top of the mounting frame so that the cover plate covers the top of the mounting space.

[0015] In one embodiment of this application, the combiner box further includes a fixed base connected to the bottom of the mounting frame for supporting the mounting frame or for fixing the mounting frame to an external mounting bracket.

[0016] This application also provides a mobile energy storage integrated cabin, which includes a container body, a battery pack, and any one of the aforementioned combiner boxes. The container body is provided with an installation chamber, and the battery pack and the combiner box are both installed in the installation chamber. The combiner box is electrically connected to the battery pack so that the battery pack can be charged or discharged through the combiner box.

[0017] This application also provides a mobile energy storage vehicle, which includes a vehicle body and the aforementioned mobile energy storage integrated module. The mobile energy storage integrated module is installed on the vehicle body so that the vehicle body can move the mobile energy storage integrated module.

[0018] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0019] In this invention, the combiner box includes a mounting frame and multiple connecting components. The mounting frame forms multiple installation spaces, and the longitudinal sides of each installation space are open, allowing external cables to extend from the longitudinal sides of the combiner box into the installation space and connect to the connecting components. This enables the combiner box to adapt to the installation requirements of mobile energy storage modules and facilitates cable routing within the module. The installation spaces have multiple vertical shelves, and each shelf houses a connecting component. The connecting components are used to connect the batteries in the battery packs, allowing multiple battery packs to be connected in parallel or series via the combiner box.

[0020] Meanwhile, the connection assembly includes an input busbar, an output busbar, and a fuse. The input and output busbars are respectively installed on opposite sides of the shelf along its longitudinal direction. The fuse is mounted on the shelf and located between the input and output busbars, electrically connected to protect the connection between them. Positioning the fuse between the input and output busbars simplifies the installation of the connection assembly and reduces its footprint.

[0021] Furthermore, the projections of the input busbars on multiple shelves in the same horizontal plane are staggered longitudinally, and the projections of the output busbars on multiple shelves in the same horizontal plane are also staggered longitudinally. This minimizes the vertical dimensions of the combiner box while ensuring safe connection between the cables and the input or output busbars, allowing the combiner box to meet the requirements of a mobile energy storage module. Additionally, the mounting surfaces of the input and output busbars face vertically, enabling operators to install cables vertically onto the input and output busbars, thus facilitating the installation and maintenance of the combiner box.

Detailed Implementation

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications will also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] Current energy storage devices are mainly fixed devices designed for specific locations. These fixed devices cannot meet temporary power demands, such as those for construction sites, highways, and mining areas. Therefore, mobile integrated energy storage units are needed to meet these needs. However, existing combiner boxes, due to the lack of consideration for cabinet size and wiring safety, result in excessively large return cabinets, making them unsuitable for mobile integrated energy storage units. Therefore, this paper proposes a combiner box to solve the above problems.

[0036] The solution is further illustrated by the following examples:

[0037] Figure 1 This is a schematic diagram of a mobile energy storage integrated cabin according to an embodiment of this utility model. Figure 2 This is a schematic diagram of the combiner box according to an embodiment of the present utility model. Figure 3 yes Figure 2 A schematic diagram of the front view of the junction box. Figure 4 yes Figure 2 Another schematic diagram of the junction box. Figure 5 yes Figure 2 A top view of the junction box. Figure 6 yes Figure 2 Side view of the junction box within its installation space. Figure 7 yes Figure 2 A schematic diagram of the inside of the junction box.

[0038] In this embodiment, for ease of description, ... Figure 2 In the diagram, AA represents the longitudinal direction of the junction box. Figure 2 The BB direction in the diagram refers to the horizontal direction of the junction box. Figure 2 The CC direction in the figure represents the vertical direction of the junction box.

[0039] Please see Figure 1 The mobile energy storage integrated cabin of this embodiment can be applied to power consumption scenarios such as construction site power supply, temporary power supply for highways and power supply for mining areas, so as to facilitate the movement, installation and disassembly of power equipment.

[0040] Specifically, the mobile energy storage module may include a container body 1, a battery pack 2, and a junction box 3. The container body 1 has an installation chamber, in which both the battery pack 2 and the junction box 3 are installed. The junction box 3 is located at the end of the container body 1 along its length to facilitate connection with external cables. The junction box 3 is electrically connected to the battery pack 2 to connect multiple batteries in the battery pack 2 in series or parallel, enabling the battery pack 2 to be charged or discharged through the junction box 3.

[0041] It should be noted that in existing combiner boxes, the excessively large vertical dimensions mean that the combiner box can only be placed in the same space as the battery pack within the container, thus occupying a portion of the space available for battery installation. The combiner box 3 of this application reduces its vertical dimensions, allowing it to be flexibly placed at the end of the container body 1. This avoids the combiner box 3 occupying the space available for battery pack installation, thereby improving the overall space utilization efficiency of the container and increasing the number or capacity of battery packs that can be installed.

[0042] In this embodiment, the size of the container body 1 can be set to the size of a standard container to facilitate the transfer and hoisting of the mobile energy storage module, making the mobile energy storage module adaptable to temporary power supply scenarios.

[0043] Meanwhile, the mobile energy storage vehicle of this embodiment may include a vehicle body and a mobile integrated energy storage module. The vehicle body is movable, and the mobile integrated energy storage module is installed on the vehicle body, so that the vehicle body can move the mobile integrated energy storage module, thereby transporting the mobile integrated energy storage module to its destination.

[0044] It should be noted that the mobile energy storage module can be directly fixed to the vehicle body, allowing for an integrated design between the vehicle and the module, thus facilitating its movement. Alternatively, the mobile energy storage module can also be detachably connected to the vehicle body, enabling easy disassembly and replacement. Furthermore, the vehicle body can also serve as a dedicated transport device for the mobile energy storage module, further simplifying its transport.

[0045] See Figure 2 , Figure 3 and Figure 4 The junction box 3 may include a mounting frame 10 and multiple connecting components 20. The mounting frame 10 forms multiple mounting spaces 11, and each mounting space 11 has multiple shelves 12 arranged vertically. Each connecting component 20 is installed within one shelf 12 and is used to connect the batteries in the battery pack 2.

[0046] Meanwhile, the connecting component 20 may include an input busbar 21, an output busbar 22, and a fuse 23. The input busbar 21 and the output busbar 22 are respectively installed on both sides of the shelf 12 in the longitudinal direction. The fuse 23 is installed on the shelf 12 and located between the input busbar 21 and the output busbar 22. The fuse 23 is electrically connected between the input busbar 21 and the output busbar 22 so that when the current or voltage between the input busbar 21 and the output busbar 22 is too large, the fuse 23 will cut off the electrical connection between the input busbar 21 and the output busbar 22, thereby protecting the circuit safety.

[0047] In this embodiment, the installation space 11 is open on both sides in the longitudinal direction, so that external cables can extend into the installation space from the two open sides of the installation space 11 and connect to the input busbar 21 or the output busbar 22, which facilitates the routing of the combiner box 3 and the external cables, and makes the combiner box 3 adaptable to and meet the routing requirements of the energy storage compartment.

[0048] See Figure 4 , Figure 5 , Figure 6 and Figure 7 The projections of the input busbars 21 on the same horizontal plane are staggered in the longitudinal direction, and the projections of the output busbars 22 on the same horizontal plane are staggered in the longitudinal direction. The mounting surfaces of the input busbars 21 and the output busbars 22 face the vertical direction, so that the operator can connect the ends of the external cables to the input busbars 21 or the output busbars 22 in the vertical direction. This makes it convenient for the operator to connect or maintain the combiner box 3 in the confined space of the energy storage compartment.

[0049] It should be noted that, because the shelves 12 are arranged vertically at intervals, and the input busbars 21 on each shelf 12 are staggered longitudinally on the same plane, and the output busbars 22 on each shelf 12 are staggered longitudinally on the same horizontal plane, the vertical dimensions of the combiner box 3 can be minimized while ensuring safe connection between external cables and busbars or maintaining sufficient safety distance between cables and busbars. This makes the combiner box 3 suitable for mobile energy storage modules. Simultaneously, because the installation space 11 is open on both longitudinal sides, external cables can be directly connected to the busbars through the open sides. This allows the combiner box 3 to fully utilize the longitudinal space within the installation space 11, optimizes the wiring of the energy storage module and the combiner box 3, and makes the combiner box 3 compact overall, thus making it suitable for mobile energy storage modules.

[0050] See Figure 1 and Figure 3 The connecting component 20 may include two input busbars 21, two output busbars 22, and two fuses 23. Specifically, the two input busbars 21 are spaced apart on the shelf 12 in the lateral direction, the two output busbars 22 are spaced apart on the shelf 12 in the lateral direction, and the two fuses 23 are spaced apart on the shelf 12 in the lateral direction. The input busbars 21, fuses 23, and output busbars 22 are arranged in a one-to-one correspondence, that is, one input busbar 21, one fuse 23, and one output busbar 22 form a connecting path.

[0051] In this embodiment, two input busbars 21 are connected to the positive and negative terminals of the battery via external cables, while two output busbars 22 are connected to the electric gun 4 via external cables. The electric gun 4 is used to connect to power-consuming or discharging equipment. That is, two connecting paths are provided on the same shelf 12 to correspond to the positive and negative terminals of the battery, respectively, so that a complete electrical circuit is formed between the battery and the power-consuming or discharging equipment.

[0052] It should be noted that the electric gun 4 may include a charging electric gun and a discharging electric gun, and the two electrical lines of the charging electric gun and the discharging electric gun are respectively connected to two output line bars 22, so that the energy storage compartment can be quickly connected to the power supply or discharge equipment through the electric gun 4 to facilitate the charging or discharging of the energy storage compartment.

[0053] In some other embodiments, each shelf 12 may be provided with two or more sets of connecting pathways for connecting the electrodes of the battery.

[0054] See Figure 3Multiple installation spaces 11 are arranged side by side along the transverse direction of the mounting frame 10. Specifically, in this embodiment, the mounting frame 10 has two installation spaces 11, and the two installation spaces 11 are arranged side by side. At the same time, each installation space 11 has two shelves 12, and each shelf 12 has two connecting passages.

[0055] In this embodiment, each battery cluster on the battery pack of the integrated energy storage compartment includes four batteries, and the combiner box 3 is provided with four shelves 12, with each shelf 12 corresponding to one battery. This allows the two connecting paths on each shelf 12 to correspond to the positive and negative terminals of the battery, thereby enabling the combiner box 3 to connect multiple batteries in parallel to facilitate battery discharge or charging.

[0056] In other embodiments, multiple mounting spaces 11 may be arranged side by side vertically along the mounting frame 10, or multiple mounting spaces 11 may be arranged side by side both vertically and horizontally along the mounting frame 10. Furthermore, each mounting space 11 may contain two or more shelves 12 to accommodate different battery clusters.

[0057] See Figure 4 The mounting frame 10 may include a support beam 13, a fixing beam 14, a connecting beam 15, a mounting beam 16, and an auxiliary beam 17.

[0058] The system includes multiple support beams 13, all of which extend vertically. A fixed beam 14 extends longitudinally and connects two support beams 13 in the longitudinal direction. Simultaneously, a connecting beam 15 extends transversely and connects multiple transverse support beams 13, thereby enabling the support beams 13, fixed beams 14, and connecting beams 15 to collectively enclose the installation space 11.

[0059] Meanwhile, the mounting beam 16 extends laterally, and both ends of the mounting beam 16 are connected to two fixed beams 14 respectively, so that the mounting beam 16 and the fixed beams 14 form a shelf 12.

[0060] It should be noted that, in the vertical direction, the support beam 13 connects to multiple fixed beams 14 to form multiple shelves 12 in the vertical direction and improve the structural strength of the mounting frame 10. In this embodiment, the mounting beam 16 is used to install the input busbar 21 or the output busbar 22, so that the input busbar 21 and the output busbar 22 are securely connected to the mounting frame 10 or the shelf 12.

[0061] Furthermore, the auxiliary beam 17 extends laterally, and its two ends are respectively connected to two fixed beams 14. The auxiliary beam 17 and the mounting beam 16 are spaced apart longitudinally, and the auxiliary beam 17 is located on the side of the mounting beam 16 facing the outside of the mounting space 11, so that the auxiliary beam 17 can be used to support external cables on the same shelf 12, improving the stability of the connection between the external cables and the input busbar 21 or the output busbar 22.

[0062] It should be noted that the support beam 13, fixed beam 14, connecting beam 15, mounting beam 16, and auxiliary beam 17 can all be made of sheet metal to improve the structural strength of the mounting frame 10. Of course, the support beam 13, fixed beam 14, connecting beam 15, mounting beam 16, and auxiliary beam 17 can also be made of wood or other materials.

[0063] See Figure 2 and Figure 4 The mounting frame 10 may be provided with a base plate 101, a box plate 102, and a cover plate 103. The base plate 101 is connected to the mounting frame 10 and located at the bottom of the mounting space 11, so that the base plate 101 can protect the bottom of the mounting frame 10. In this embodiment, in the shelf 12 at the bottom of the mounting space 11, the mounting beam 16 and the base plate 101 are integrally formed.

[0064] Meanwhile, the box panel 102 is connected to both ends of the mounting frame 10 in the lateral direction. Specifically, the box panel 102 is connected to the support beam 13 at the upper lateral end of the mounting frame 10, so that the box panel 102 provides protection for the connecting components 20 inside the mounting frame 10 in the lateral direction.

[0065] In addition, the cover plate 103 is detachably connected to the top of the mounting bracket 10 so that the cover plate 103 covers the top of the mounting space 11, thereby facilitating the opening or closing of the top cover plate of the junction box 3, and thus facilitating the installation or maintenance of the junction box 3.

[0066] It should be noted that the base plate 101, box plate 102 and cover plate 103 can all be made of sheet metal.

[0067] See Figure 2 The junction box 3 may also include a fixed base 104. The fixed base 104 is connected to the bottom of the mounting frame 10 to support the mounting frame 10 or to fix the mounting frame 10 to an external mounting bracket. For example, the junction box 3 is mounted on the bottom plate of the mounting cavity of the container body 1 via the fixed base 104, such that the junction box 3 is spaced apart from the bottom plate of the mounting cavity. Specifically, the fixed base 104 can be connected to the junction box 3 and the container body 1 by bolts.

[0068] It should be noted that the fixed base 104 can be made of sheet metal.

[0069] See Figure 4 and Figure 5 Both the input busbar 21 and the output busbar 22 can be provided with multiple mounting holes 24. These mounting holes 24 are through holes and are used to connect external cables and fuses 23. Furthermore, the mounting holes 24 on the input busbar 21 and the output busbar 22 are spaced apart along their respective lengths, facilitating the connection of multiple external cables to either the input busbar 21 or the output busbar 22.

[0070] In this embodiment, the end of the external cable is provided with a copper terminal, which is connected to the mounting hole 24 of the input line bus 21 or the output line bus 22 by bolts or screws, thereby fixing the external cable to the input line bus 21 or the output line bus 22.

[0071] It should be noted that, on the same shelf 12, the copper terminals on the input busbar 21 and the copper terminals on the output busbar 22 can be staggered laterally.

[0072] In some other embodiments, the end of the external cable can be configured as a snap-fit ​​structure, and the input busbar 21 and the output busbar 22 are provided with snap-fit ​​structures that cooperate with the snap-fit ​​structure, so that the external cable can be stably connected to the input busbar 21 and the output busbar 22.

[0073] It should be noted that since the input busbars 21 or output busbars 22 on each shelf 12 are staggered in the longitudinal direction, when connecting external cables to the input busbars 21 or output busbars 22, the operator can reach down into the installation space 11 from the top of the junction box 3 and tighten or loosen the bolts or screws, which facilitates the installation or maintenance of external cables.

[0074] See Figure 3 , Figure 4 and Figure 7 Both the input busbar 21 and the output busbar 22 are connected to the shelf 12 via an insulating member 25. Specifically, the insulating member 25 is connected to the mounting holes 24 of the input busbar 21 or the output busbar 22 by screws or bolts, and is also connected to the mounting beam 16 of the shelf 12 by screws or bolts, so that the input busbar 21 and the output busbar 22 are spaced apart from the mounting beam 16, and the input busbar 21 and the output busbar 22 are insulated from each other to prevent leakage.

[0075] In this embodiment, the insulating component 25 can be configured as a component made of insulating material, such as insulating ceramic or insulating plastic.

[0076] Figure 8 yes Figure 2 A schematic diagram of the connecting components of the junction box.

[0077] See Figure 7 and Figure 8 The connecting component 20 may further include a connector 26. The connector 26 includes a first connecting portion 261 for connecting the fuse 23 and a second connecting portion 262 for connecting the input busbar 21 or the output busbar 22. The first connecting portion 261 and the second connecting portion 262 are connected sequentially and arranged at an included angle. Specifically, the first connecting portion 261 and the second connecting portion 262 are arranged at a right angle, so that after the fuse 23 is connected to the input busbar 21 and the output busbar 22 via the connector 26, the fuse 23 can be spaced apart from the shelf 12, thus allowing the fuse 23 to be suspended.

[0078] In this embodiment, the second connecting part 262 is provided with a mounting hole 263, which is used to connect the insulating member 25 so that the connecting member 26 can be fixed on the shelf 12 through the insulating member 25, and the fuse 23 can be stably connected to the shelf 12 through the connecting member 26.

[0079] In summary, the mounting frame 10 forms multiple mounting spaces 11, with both longitudinal sides of each space open, allowing external cables to extend from both longitudinal sides of the combiner box 3 into the mounting space 11 and connect to the connecting component 20. This enables the combiner box 3 to adapt to the installation requirements of the mobile energy storage integrated module and facilitates cable routing within the module. The mounting space 11 has multiple vertical shelves 12, and each shelf 12 is equipped with a connecting component 20. The connecting component 20 is used to connect the batteries in the battery pack 2, allowing multiple battery packs 2 to be connected in parallel or in series via the combiner box 3.

[0080] Meanwhile, the connecting component 20 includes an input busbar 21, an output busbar 22, and a fuse 23. The input busbar 21 and the output busbar 22 are respectively installed on both sides of the longitudinal direction of the shelf 12. The fuse 23 is installed on the shelf 12 and located between the input busbar 21 and the output busbar 22, and is electrically connected between the input busbar 21 and the output busbar 22, so that the fuse 23 can protect the connection between the input busbar 21 and the output busbar 22. The location of the fuse 23 between the input busbar 21 and the output busbar 22 simplifies the installation of the connecting component 20 and reduces the installation volume occupied by the connecting component 20.

[0081] Furthermore, the projections of the input busbars 21 on multiple shelves 12 in the same horizontal plane are staggered in the longitudinal direction, and the projections of the output busbars 22 on multiple shelves 12 in the same horizontal plane are also staggered in the longitudinal direction. This minimizes the size of the combiner box 3 while ensuring a safe connection between the cables and the input busbars 21 or output busbars 22, allowing the combiner box 3 to meet the requirements of a mobile energy storage module. Moreover, the mounting surfaces of the input busbars 21 and output busbars 22 face vertically, enabling operators to install cables vertically onto the input busbars 21 and output busbars 22, thus facilitating the installation and maintenance of the combiner box 3.

[0082] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
