Description

Technical Field

[0001] This utility model relates to the field of control box technology, and more specifically to a control box and an energy storage device. Background Technology

[0002] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the high-voltage control box 1' of the energy storage device typically includes components such as a disconnect switch 12' and a fuse 18', which are connected by copper busbars to form a circuit.

[0003] In related technologies, along the depth direction of the high-voltage control box 1', the various components in the high-voltage control box are often connected by copper busbars 19' with multiple flat bends and / or twists, which makes the installation of the high-voltage control box 1' difficult and inefficient. Utility Model Content

[0004] The present invention aims to at least solve or improve the technical problem in the related art where the copper busbar inside the control box is bent and / or twisted multiple times along the depth direction of the control box, resulting in the difficulty of installing the control box.

[0005] Therefore, a control box is proposed in the first aspect of this utility model.

[0006] A second aspect of this utility model provides an energy storage device.

[0007] In view of the above, according to a first aspect of the present invention, the present invention provides a control box, comprising: a box body, a disconnect switch, a first plug, a second plug, a third plug, a first contactor, a second contactor, a fuse, and a plurality of copper busbars; at least a portion of each of the disconnect switch, the first plug, the second plug, and the third plug is located within the box body and fixed to the box body; each of the first contactor, the second contactor, and the fuse is located within the box body and fixed to the box body; the disconnect switch, the first plug, the second plug, the third plug, the first contactor, the second contactor, and the fuse form a circuit through the plurality of copper busbars; wherein, all copper busbars are flat plate structures, and along the depth direction of the box body, the connection positions of the first contactor, the second contactor, the disconnect switch, and the fuse with the copper busbars are located within the same height range to match the copper busbars.

[0008] The control box proposed in this utility model includes a box body, a disconnect switch, a first plug, a second plug, a third plug, a first contactor, a second contactor, and a fuse. At least a portion of the disconnect switch, the first plug, the second plug, and the third plug are disposed inside the box body. The first contactor, the second contactor, and the fuse are disposed inside the box body. Thus, the box body can provide protection for the disconnect switch, the first plug, the second plug, the third plug, the first contactor, the second contactor, and the fuse.

[0009] The disconnect switch, first plug, second plug, third plug, first contactor, second contactor, and fuse form a circuit through multiple copper busbars. All copper busbars adopt a flat structure with flat and / or twisted bends along the depth direction of the box. To achieve this structure, the connection points of the first contactor, second contactor, disconnect switch, and fuse to the copper busbars are located within the same height range along the depth direction of the box. This allows the flat copper busbars to connect any two of the disconnect switch, first plug, second plug, third plug, first contactor, second contactor, and fuse. Consequently, the height difference between the various components within the box does not require front and rear fixing of the copper busbars during installation, as all copper busbars are approximately at the same height level, thus reducing the assembly difficulty of the control box.

[0010] In some technical solutions, optionally, the number of disconnecting switches is one, and the number of first plugs, second plugs, third plugs, first contactors, second contactors, and fuses are two each; wherein, the two first plugs are respectively connected to the first output terminal and the second output terminal of the disconnecting switch; one second plug and one first contactor are connected in series, and the two first contactors are connected in parallel to the first input terminal of the disconnecting switch; one third plug, one fuse, and one second contactor are connected in series, and the two second contactors are connected in parallel to the second input terminal of the disconnecting switch.

[0011] In this technical solution, there is one disconnect switch and two first plugs. One first plug is connected to the first output terminal of the disconnect switch via a copper busbar, and the other first plug is connected to the second output terminal of the disconnect switch via a copper busbar. The first plug and the second plug serve as output plugs and can be connected to external loads.

[0012] There are two second plugs and two first contactors. One second plug is connected to one first contactor via a copper busbar, and the other second plug is connected to another first contactor via a copper busbar. The two first contactors are connected in parallel to the first input terminal of the disconnect switch via a copper busbar.

[0013] The number of third plugs, second contactors, and fuses are all two. One third plug is connected to one fuse via a copper busbar, one fuse is connected to one second contactor via a copper busbar, another third plug is connected to another fuse via a copper busbar, another fuse is connected to another second contactor via a copper busbar, and the two second contactors are connected to the second output terminal of the disconnecting switch via copper busbars.

[0014] The two second plugs can be connected to the positive terminals of the two battery packs respectively, and the two third plugs can be connected to the negative terminals of the two battery packs respectively; or the two second plugs can be connected to the negative terminals of the two battery packs respectively, and the two third plugs can be connected to the positive terminals of the two battery packs respectively.

[0015] The two first plugs provide positive and negative terminals to the load, forming a circuit to power the load.

[0016] In other words, two battery packs can share a single disconnect switch, saving costs. Furthermore, reducing the space occupied by the disconnect switch inside the box helps to miniaturize the control box. Also, since a single disconnect switch does not need to be stacked, it is easier to achieve a configuration where the connection points of the first contactor, second contactor, disconnect switch, fuse, and copper busbar are all within the same height range.

[0017] In some technical solutions, optionally, the isolating switch, the first contactor, and the fuse are arranged in sequence along the width direction of the box; the fuse and the second contactor are arranged in sequence along the height direction of the box; and the first plug, the second plug, and the third plug are arranged in sequence along the width direction of the box.

[0018] In this technical solution, the disconnecting switch, the first contactor, and the fuse are arranged in sequence along the width of the box. Since the first contactor is directly connected to the fuse through a copper busbar, placing the first contactor between the fuse and the disconnecting switch helps to shorten the length of the copper busbar between the first contactor and the disconnecting switch, thus saving costs.

[0019] Along the height of the housing, the fuse and the second contactor are arranged in sequence. The second contactor and the first contactor are located on opposite sides of the fuse, which makes the arrangement of the devices neater and makes it less likely for the first contactor and the second contactor to be confused.

[0020] Along the width of the box, the first plug, the second plug, and the third plug are arranged in sequence, making the arrangement of the first plug, the second plug, and the third plug more neat and reducing the possibility of confusion among the three.

[0021] Furthermore, along the width of the box, the disconnect switch, the first contactor, and the fuse are arranged in sequence, as are the first plug, the second plug, and the third plug. This arrangement allows the positions of the first plug and the disconnect switch to be matched, thus shortening the length of the copper busbar between the first plug and the disconnect switch. It also allows the positions of the second plug and the first contactor to be matched, thus shortening the length of the copper busbar between the second plug and the first contactor. Finally, it allows the positions of the third plug and the fuse to be matched, thus shortening the length of the copper busbar between the third plug and the fuse.

[0022] Furthermore, this setup allows for a simpler copper busbar arrangement between components, more rational path matching of the copper busbars, and makes it easier to place all copper busbars on the same layer.

[0023] In some technical solutions, optionally, the multiple copper busbars include: a first copper busbar connected to a first plug and a disconnecting switch; a second copper busbar connected to a second plug and a first contactor; a third copper busbar connected to two first contactors and a disconnecting switch; a fourth copper busbar connected to a third plug and a fuse; a fifth copper busbar connected to the fuse and a second contactor; and a sixth copper busbar connected to two second contactors and a disconnecting switch.

[0024] In this technical solution, the multiple copper busbars include a first copper busbar, a second copper busbar, a third copper busbar, a fourth copper busbar, a fifth copper busbar, and a sixth copper busbar.

[0025] One end of the first copper busbar is connected to the first plug, and the other end of the first copper busbar is connected to the disconnecting switch; one end of the second copper busbar is connected to the second plug, and the other end of the second copper busbar is connected to the first contactor; one end of the third copper busbar is connected to a first contactor, the middle section of the third copper busbar is connected to another first contactor, and the other end of the third copper busbar is connected to the disconnecting switch; one end of the fourth copper busbar is connected to the third plug, and the other end of the fourth copper busbar is connected to the fuse; one end of the fifth copper busbar is connected to the fuse, and the other end of the fifth copper busbar is connected to the second contactor; one end of the sixth copper busbar is connected to a second contactor, the middle section of the sixth copper busbar is connected to another second contactor, and the other end of the sixth copper busbar is connected to the disconnecting switch.

[0026] The copper busbars are used to make electrical connections between the various components, thereby forming a circuit. This design also makes the copper busbars more neatly arranged and helps to place them on the same layer.

[0027] In some technical solutions, the control box may optionally include: a first adapter portion fixed to the box body; a second adapter portion fixed to the box body; wherein the first adapter portion and the second adapter portion are arranged along the height direction of the box body, and along the width direction of the box body, the first adapter portion and the second adapter portion are located between the disconnecting switch and the fuse; the sixth copper busbar includes: a first sub-copper busbar connected to the two second contactors and the first adapter portion; a second sub-copper busbar connected to the first adapter portion and the second adapter portion; and a third sub-copper busbar connected to the second adapter portion and the disconnecting switch.

[0028] In this technical solution, the control box also includes a first adapter and a second adapter, which are fixed inside the box. The first adapter and the second adapter are arranged along the height direction of the box and are located between the disconnect switch and the fuse along the width direction of the box.

[0029] The sixth copper busbar includes a first sub-copper busbar, a second sub-copper busbar, and a third sub-copper busbar. One end of the first sub-copper busbar is connected to a second contactor, and the middle area of ​​the first sub-copper busbar is connected to another second contactor. The other end of the sixth copper busbar is connected to a first transition section. One end of the second sub-copper busbar is connected to the first transition section, and the other end of the second sub-copper busbar is connected to a second transition section. One end of the third sub-copper busbar is connected to the second transition section, and the other end of the third sub-copper busbar is connected to a disconnect switch.

[0030] The first and second sub-copper busbars are electrically connected, and the second and third sub-copper busbars are electrically connected.

[0031] Furthermore, this structure allows the first and second sub-copper busbars to be distributed at right angles, as well as the second and third sub-copper busbars, making the arrangement of the copper busbars more orderly and facilitating their placement on the same layer.

[0032] In some technical solutions, optionally, the disconnecting switch includes: a switch part fixed to the housing; and a handle part connected to the switch part, the handle part being located outside the housing and between the first plug and the second plug.

[0033] In this technical solution, the disconnecting switch includes a switch part and a handle part. The switch part is fixed inside the housing, and the handle part is fixed outside the housing. The handle part and the switch part are connected, so the state of the switch can be changed through the handle part. Furthermore, the handle part is located between the first plug and the second plug, so that the copper busbar between the first plug and the disconnecting switch and the copper busbar between the second plug and the first contactor will not interfere with the disconnecting switch. Neither of them needs to avoid the disconnecting switch, which makes it easier to set all the copper busbars on the same layer.

[0034] In some technical solutions, the fuse may optionally include a first fuse and a second fuse connected in series; wherein the first fuse and the second fuse are arranged along the height direction of the housing.

[0035] In this technical solution, the fuse includes a first fuse and a second fuse, which are connected in series to achieve protection functions such as overcurrent, overvoltage, or overtemperature.

[0036] The first and second fuses are arranged along the height of the box, so that the components are arranged in two directions, which can make better use of the space inside the box and is conducive to miniaturization of the box.

[0037] In some technical solutions, optionally, the multiple copper busbars also include a seventh copper busbar connected to the first fuse and the second fuse; wherein, along the depth direction of the housing, the connection positions of the first fuse and the second fuse with the seventh copper busbar are located within the same height range to match the seventh copper busbar.

[0038] In this technical solution, the multiple copper busbars also include a seventh copper busbar. One end of the seventh copper busbar is connected to the first fuse, and the other end of the seventh copper busbar is connected to another fuse. The seventh copper busbar has a flat plate structure. Along the depth direction of the box, the connection positions of the first fuse and the second fuse with the seventh copper busbar are located within the same height range to match the seventh copper busbar.

[0039] This ensures that the connection points of the first fuse, the second fuse, the first contactor, the second contactor, and the disconnecting switch with the copper busbar are within the same height range, thus better matching the flat copper busbar structure.

[0040] In some technical solutions, optionally, the housing includes: a body, with a first contactor and a second contactor fixed to the body; a first bracket fixed to the body, with a disconnecting switch fixed to the first bracket, the first bracket being used for leveling the disconnecting switch relative to the first contactor and the second contactor; and a second bracket fixed to the body, with a fuse fixed to the second bracket, the second bracket being used for leveling the fuse relative to the first contactor and the second contactor.

[0041] In this technical solution, the box includes a main body, a first bracket and a second bracket, both of which are fixed to the main body. The first contactor is fixed to the main body, the second contactor is fixed to the main body, the disconnecting switch is fixed to the first bracket, and the fuse is fixed to the second bracket.

[0042] The first bracket is used to level the disconnect switch relative to the first contactor and the second contactor, so that the connection positions of the first contactor, the second contactor, and the disconnect switch with the copper busbar are within the same height range.

[0043] The second bracket is used to level the fuse relative to the first and second contactors, so that the connection positions of the first contactor, the second contactor, and the fuse to the copper busbar are within the same height range.

[0044] Since the contactor is usually quite tall, by using the first bracket to raise the disconnecting switch and the second bracket to raise the fuse, the connection positions of the disconnecting switch, the first contactor, the second contactor, and the fuse with the copper busbar can be roughly in the same plane. Moreover, this design structure is simple and convenient to produce and install.

[0045] According to a second aspect of the present invention, the present invention provides an energy storage device, comprising: a control box as described in the first aspect embodiment.

[0046] The energy storage device proposed in this utility model includes the control box as described in the first aspect embodiment, and therefore has all the beneficial effects of the control box as described in the first aspect embodiment, which will not be described in detail here.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] The following reference Figures 5 to 8 This describes the control box 1 and energy storage device provided according to some embodiments of the present invention, wherein, Figure 8In this context, FUSE and FU represent fuses, which are overcurrent protection devices and need to be replaced after blowing.

[0064] In view of this, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, according to a first aspect embodiment of the present invention, a control box 1 is provided. The control box 1 includes a box body 11, a disconnect switch 12, a first contactor 16, a second contactor 17, and a fuse 18. Electrical protection and safety isolation functions are achieved through the disconnect switch 12, the first contactor 16, the second contactor 17, and the fuse 18. The disconnect switch 12, the first contactor 16, the second contactor 17, and the fuse 18 are all fixed to the box body 11.

[0065] The first contactor 16 and the fuse 18 can be connected to the positive and negative terminals of the battery pack, respectively.

[0066] At least a portion of the disconnect switch 12 is located inside the housing 11, and the disconnect switch 12 is fixed to the housing 11; the first contactor 16 is located inside the housing 11 and is fixed to the housing 11; the second contactor 17 is located inside the housing 11 and is fixed to the housing 11; and the fuse 18 is located inside the housing 11 and is fixed to the housing 11.

[0067] Furthermore, the control box 1 also includes a first plug 13, a second plug 14 and a third plug 15. At least a portion of the first plug 13 is located inside the box body 11 and is fixed to the box body 11. At least a portion of the second plug 14 is located inside the box body 11 and is fixed to the box body 11. At least a portion of the third plug 15 is located inside the box body 11 and is fixed to the box body 11.

[0068] Multiple copper busbars 19 connect to the disconnecting switch 12, the first plug 13, the second plug 14, the third plug 15, the first contactor 16, the second contactor 17, and the fuse 18, thereby forming a circuit. All copper busbars 19 are flat and are positioned along the depth direction OA of the housing 11. The connection points of the first contactor 16, the second contactor 17, the disconnecting switch 12, and the fuse 18 with the copper busbars 19 are located within the same height range to match the copper busbars 19.

[0069] The control box 1 proposed in this utility model includes a box body 11, a disconnect switch 12, a first plug 13, a second plug 14, a third plug 15, a first contactor 16, a second contactor 17, and a fuse 18. At least a portion of the disconnect switch 12, the first plug 13, the second plug 14, and the third plug 15 are disposed inside the box body 11. The first contactor 16, the second contactor 17, and the fuse 18 are disposed inside the box body 11. Thus, the box body 11 can provide protection for the disconnect switch 12, the first plug 13, the second plug 14, the third plug 15, the first contactor 16, the second contactor 17, and the fuse 18.

[0070] The disconnect switch 12, first plug 13, second plug 14, third plug 15, first contactor 16, second contactor 17, and fuse 18 form a circuit through multiple copper busbars 19. All copper busbars 19 adopt a flat structure. Along the depth direction OA of the box 11, the copper busbars 19 have a flat bend and / or twist bend structure. In order to achieve this structure of the copper busbars 19, along the depth direction OA of the box 11, the connection positions of the first contactor 16, second contactor 17, disconnect switch 12, and fuse 18 with the copper busbars 19 are located within the same height range. This allows the flat copper busbars 19 to connect any two of the disconnect switch 12, first plug 13, second plug 14, third plug 15, first contactor 16, second contactor 17, and fuse 18. As a result, when installing the copper busbars 19, the height difference between the various components in the box 11 does not require front and rear fixing of the copper busbars 19. All the copper busbars 19 are roughly within the same height layer, thereby reducing the assembly difficulty of the control box 1.

[0071] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some technical solutions, the control box 1 may optionally include a disconnect switch 12, two first plugs 13, two second plugs 14, two third plugs 15, two first contactors 16, two second contactors 17, and two fuses 18.

[0072] One of the first plugs 13 is connected to the first output terminal 121 of the disconnector switch 12 via a copper busbar 19, and the other first plug 13 is connected to the second output terminal 122 of the disconnector switch 12 via a copper busbar 19.

[0073] A second plug 14 and a first contactor 16 are connected in series via a copper busbar 19, another second plug 14 and another first contactor 16 are connected in series via a copper busbar 19, and two first contactors 16 are connected in parallel via a copper busbar 19 to the first input terminal 123 of the disconnect switch 12.

[0074] A third plug 15, a fuse 18, and a second contactor 17 are connected in series via a copper busbar 19. Another third plug 15, another fuse 18, and another second contactor 17 are connected in series via a copper busbar 19. Two second contactors 17 are connected in parallel via a copper busbar 19 to the second input terminal 124 of the disconnector switch 12.

[0075] In this embodiment, there is one disconnect switch 12 and two first plugs 13. One first plug 13 is connected to the first output terminal 121 of the disconnect switch 12 via a copper busbar 19, and the other first plug 13 is connected to the second output terminal 122 of the disconnect switch 12 via a copper busbar 19. The first plug 13 and the second plug 14 serve as output plugs and can be connected to external loads.

[0076] There are two second plugs 14 and two first contactors 16. One second plug 14 is connected to one first contactor 16 through a copper busbar 19, and the other second plug 14 is connected to another first contactor 16 through a copper busbar 19. The two first contactors 16 are connected in parallel to the first input terminal 123 of the disconnect switch 12 through the copper busbar 19.

[0077] The number of third plug 15, second contactor 17 and fuse 18 are all two. One third plug 15 is connected to one fuse 18 through copper busbar 19, one fuse 18 is connected to one second contactor 17 through copper busbar 19, another third plug 15 is connected to another fuse 18 through copper busbar 19, another fuse 18 is connected to another second contactor 17 through copper busbar 19, and the two second contactors 17 are connected to the second output terminal 122 of disconnector switch 12 through copper busbar 19.

[0078] The two second plugs 14 can be connected to the positive terminals of the two battery packs respectively, and the two third plugs 15 can be connected to the negative terminals of the two battery packs respectively; or the two second plugs 14 can be connected to the negative terminals of the two battery packs respectively, and the two third plugs 15 can be connected to the positive terminals of the two battery packs respectively.

[0079] The two first plugs 13 provide positive and negative terminals to the load to form a circuit, thereby supplying power to the load.

[0080] In other words, the two battery packs can share a single disconnect switch 12, saving costs. Furthermore, reducing the space occupied by the disconnect switch 12 inside the housing 11 helps to miniaturize the control box 1. Also, since the disconnect switch 12 does not need to be stacked, it is easier to achieve the arrangement where the connection positions of the first contactor 16, the second contactor 17, the disconnect switch 12, and the fuse 18 are within the same height range as the copper busbar 19.

[0081] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the disconnect switch 12, the first contactor 16 and the fuse 18 are arranged sequentially along the width direction OC of the housing 11, that is, the first contactor 16 is located between the fuse 18 and the disconnect switch 12.

[0082] Along the height direction OB of the housing 11, the fuse 18 and the second contactor 17 are arranged in sequence.

[0083] Along the width direction OC of the housing 11, the first plug 13, the second plug 14 and the third plug 15 are arranged in sequence.

[0084] In this embodiment, the disconnect switch 12, the first contactor 16 and the fuse 18 are arranged in sequence along the width direction OC of the housing 11. Since the first contactor 16 is directly connected to the fuse 18 through the copper busbar 19, placing the first contactor 16 between the fuse 18 and the disconnect switch 12 helps to shorten the length of the copper busbar 19 between the first contactor 16 and the disconnect switch 12, thus saving costs.

[0085] Along the height direction OB of the housing 11, the fuse 18 and the second contactor 17 are arranged in sequence. The second contactor 17 and the first contactor 16 are located in two directions of the fuse 18, which makes the arrangement of the devices more neat and the first contactor 16 and the second contactor 17 less likely to be confused.

[0086] Along the width direction OC of the housing 11, the first plug 13, the second plug 14 and the third plug 15 are arranged in sequence, making the arrangement of the first plug 13, the second plug 14 and the third plug 15 more neat and reducing the possibility of confusion among the three.

[0134] Since the contactor is usually quite tall, the disconnect switch 12 is raised by the first bracket 112 and the fuse 18 is raised by the second bracket 113. This allows the connection positions of the disconnect switch 12, the first contactor 16, the second contactor 17 and the fuse 18 with the copper busbar 19 to be roughly in the same plane.

[0136] The control box 1 provided by this utility model, through optimization of the circuit schematic, changes the control of two circuits by two isolating switches 12 to control two circuits by a single isolating switch 12, simplifying the structure of the control box 1, reducing the depth of the box body 11 by 50%, and reducing the cost of the copper busbars 19 by 70%. Furthermore, through optimized structural design and adjustment of the bottom support height of each component, using the contactor (the tallest component) as the positioning surface, the height of all copper busbars 19 is designed to be within the same plane, with no height difference. This eliminates the need for bending processing, significantly improving processing efficiency and accuracy, reducing material usage, and lowering costs.
