Description

Technical Field

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

[0002] Currently, battery compartment designs are becoming increasingly compact and dense. While space is being compressed, the battery system capacity is actually increasing. The control box is the monitoring brain of this battery system, housing most of the various electrical components and display controls. In containerized energy storage systems with the battery compartment as the main body, the space of the control box is also being compressed to accommodate the compact design of the battery compartment.

[0003] Currently, in order to dissipate heat from the control box, corresponding air ducts are usually installed inside the control box to connect the control box with the external environment. This reduces the volume of installation space for electrical components when the space of the control box is compressed, resulting in low space utilization of the control box and difficulty in ensuring electrical design safety.

[0011] Furthermore, along the second direction, at least two through holes are provided at intervals on the top wall.

[0012] Furthermore, the receiving groove also includes a first sidewall, a second sidewall, a third sidewall, and a bottom wall. Along the third direction, the first sidewall is located on the side of the receiving groove away from the door panel.

Furthermore, even when the space of the control box is compressed, the through hole does not reduce the size of the mounting cavity, thus providing sufficient space for the mounting assembly and electrical components, greatly improving the space utilization of the control box and ensuring its electrical safety.

[0037] Currently, the control box serves as the monitoring brain of the battery system, housing most electrical components and display / control systems. This necessitates careful consideration of the internal space design of the control box. Especially in containerized energy storage battery systems with a battery compartment as the main component, the space within the control box is extremely limited. Therefore, how to rationally utilize this space while ensuring safe distances between various electrical components and preventing disruption to the long-term operation of the control box has become a pressing technical challenge. To address this, the inventors of this invention have discovered that current control box heat dissipation designs typically involve installing air ducts within the control box to connect it to the external environment. These ducts require one or more side panels to enclose the control box walls. This design reduces the volume of space available for installing electrical components, resulting in low space utilization and compromising electrical safety.

[0038] To address the aforementioned problems, the first embodiment of this utility model provides a control box, please refer to [link / reference needed]. Figures 1 to 3 The control box includes a control box body 10 and a mounting assembly 20. The control box body 10 has a mounting cavity 101 inside, and at least one through hole 102 is provided on the side wall of the control box body 10, and the at least one through hole 102 communicates with the mounting cavity 101.

[0039] like Figure 2 As shown, the mounting assembly 20 includes a mounting component 21 and at least one wiring trough 22, both of which are mounted on the inner wall of the mounting cavity 101. The mounting component 21 is used to connect at least electrical components, such as fuses, circuit breakers, and switches. The mounting component 21 and the wiring trough 22 are spaced apart to ensure that the distance between the electrical components on the mounting component 21 and the wires in the wiring trough 22 meets electrical safety requirements, minimizing the risk of wire wear, short circuits, poor heat dissipation, and electromagnetic interference. At least one through hole 102 is positioned opposite to and communicates with at least one wiring trough 22. Therefore, the control box body 10 does not need to be enclosed by numerous side panels to form an air duct; the mounting cavity 101 of the control box can be connected to the external environment through at least one through hole 102, allowing airflow inside the mounting cavity 101 to exchange with airflow in the external environment, thus achieving heat dissipation. Secondly, the wires connecting the electrical components can also be passed through at least one through hole 102 into the wiring trough 22 to connect with the electrical components, so that the through hole 102 can meet the wiring requirements and also provide some heat dissipation for the control box, resulting in extremely high space utilization.

[0040] As can be seen, the control box provided in this embodiment includes a control box body 10 and a mounting assembly 20. The control box body 10 has at least one through hole 102 communicating with its mounting cavity 101 on its side wall. The mounting component 21 and the wiring trough 22 of the mounting assembly 20 are both mounted on the inner wall of the mounting cavity 101. The mounting component 21 is used to connect at least electrical components. The mounting component 21 and the wiring trough 22 are spaced apart from each other so that the distance between the electrical components mounted on the mounting component 21 and the wires laid in the wiring trough 22 meets the electrical design safety requirements. At least one through hole 102 is opposite to and communicates with at least one wiring trough 22. Therefore, the through hole 102 in the control box not only allows wires to pass through the wiring trough 22 to connect electrical components, but also allows for the exchange of air inside the mounting cavity 101 with the external environment, thus meeting the heat dissipation requirements of the control box. Furthermore, even when the space of the control box is compressed, the through hole 102 will not reduce the size of the mounting cavity 101, thus leaving enough space for the installation of the mounting components 20 and electrical components, greatly improving the space utilization of the control box and ensuring the electrical safety of the control box.

[0041] The control box body 10 includes a box body 11 and a door panel 12. A receiving groove 110 is provided inside the box body 11. Along a first direction (e.g., ...) Figure 2 (In the direction indicated by the middle arrow X), the receiving groove 110 includes a top wall 111 located at the top of the housing 11. At least one through hole 102 is provided through the top wall 111, and the mounting component 21 and the wiring groove 22 are mounted on at least one inner wall surface of the receiving groove 110 offset from the top wall 111. The door panel 12 is connected to the housing 11 and can be rotated to a first position covering the receiving groove 110 and a second position opening the receiving groove 110. When the door panel 12 is in the first position, it forms a mounting cavity 101 with the inner wall surface of the receiving groove 110. In this embodiment, the door panel 12 may include one, two, three, or any other number greater than one, depending on actual needs. This embodiment does not impose a unique limitation.

[0042] In this embodiment, the through hole 102 is located on the top wall 111 of the housing 11, which does not occupy the space inside the mounting cavity 101, reserving sufficient installation space for electrical components. Furthermore, the hot airflow (which has a lower density and lighter weight) inside the mounting cavity 101 can be discharged promptly through the through hole 102 on the top wall 111 after rising, improving heat dissipation and efficiency. Secondly, this embodiment can also install the mounting component 21 (such as a guide rail 211) and the wiring trough 22 on at least one inner wall surface other than the top wall 111, so that the installation gap between the mounting component 21 and the wiring trough 22 can accommodate the installation of most electrical components.

[0043] Along the second direction (e.g.) Figure 2(In the direction indicated by the middle arrow Y), at least two through holes 102 are provided at intervals on the top wall 111. These through holes 102 allow for heat dissipation of the control box, further improving heat dissipation efficiency and effectiveness. The number of through holes 102 on the top wall 111 can be one of two, three, four, five, or any other number greater than two. Of the at least two through holes 102 on the top wall 111, at least one through hole 102 can be configured to communicate only with the mounting cavity 101 for heat dissipation, while at least another through hole 102 communicates with both the mounting cavity 101 and the wiring trough 22. This allows for both heat dissipation and the passage of wires into the wiring trough 22, resulting in high space utilization.

[0044] In this embodiment, the receiving groove 110 further includes a first sidewall 112, a second sidewall 113, a third sidewall 114, and a bottom wall 115. Along a third direction (e.g.) Figure 2 (In the direction indicated by the middle arrow Z), the first sidewall 112 is located on the side of the receiving groove 110 away from the door panel 12. Along the second direction, the second sidewall 113 and the third sidewall 114 are located on opposite sides of the receiving groove 110. Along the first direction, the bottom wall 115 is located at the bottom of the receiving groove 110. The first sidewall 112, the second sidewall 113, the third sidewall 114, and the bottom wall 115 are all equipped with mounting components 21 and wiring channels 22. Thus, in this embodiment, when mounting components 21 and wiring channels 22 are installed on all four inner walls of the receiving groove 110 except for the top wall 111, it can not only meet the installation of a certain number of electrical components, but also, when the space at the top wall 111 is not occupied, reserve sufficient space for electrical components installed on other walls, thereby improving electrical safety.

[0045] In this embodiment, the mounting component 21 includes multiple guide rails 211. Electrical components are engaged with the guide rails 211 via their own locking slots that are adapted to the guide rails 211, making assembly convenient and easy to disassemble. At least one guide rail 211 is provided on each of the first sidewall 112, second sidewall 113, third sidewall 114, and bottom wall 115. Each guide rail 211 has a wiring groove 22 on at least one side along its length, and the guide rails 211 and the corresponding wiring grooves 22 are arranged perpendicularly to each other. This makes the layout of the guide rails 211 and the corresponding wiring grooves 22 on the corresponding wall surface neater and more reasonable, achieving full utilization of the limited installation area of ​​the corresponding wall surface. Alternatively, each guide rail 211 has a wiring groove 22 on at least one side along its width, and the guide rails 211 are arranged parallel to each other. This avoids occupying too much space on the corresponding wall surface due to at least one of them being inclined relative to at least the other, and ensures that each electrical component on the guide rail 211 maintains a safe electrical distance from the wiring groove 22.

[0046] In this embodiment, the spacing between the guide rails 211 and the wiring troughs 22 on each wall surface can be determined according to the electrical components to be installed. For example, if the largest device installed on the guide rail 211 is a fuse, the distance between the wiring troughs 22 on opposite sides of the guide rail 211 in the width direction can be set to be no less than the width of the fuse. If the device installed on the guide rail 211 is a switch, the distance between the guide rail 211 and the wiring trough 22 is set based on the width of the switch (e.g., 200mm) to ensure that the switch will not interfere with the wiring trough 22 after installation, or the distance between the wiring troughs 22 on opposite sides of the guide rail 211 in the width direction is no less than 200mm, etc., to ensure that the electrical components have a safe distance from the wiring troughs 22 after installation.

[0047] like Figure 3 As shown, along the length of the guide rail 211, there is a first gap between the guide rail 211 and the wiring groove 22, and along the width of the guide rail 211, there is a second gap between the guide rail 211 and the wiring groove 22, the second gap being larger than the first gap. The space where the second gap is located is usually the space occupied by electrical components after they are installed on the guide rail 211. In this embodiment, the second gap is made larger than the first gap, which not only ensures the electrical safety of electrical components and wires, but also saves space along the length of the guide rail 211 while compressing the overall volume of the control box.

[0048] In this embodiment, when multiple wiring channels 22 are included, at least one wiring channel 22 has its opposite ends positioned opposite to the through hole 102. For example, on the first sidewall 112, when the wiring channels 22 located on opposite sides of the first sidewall 112 along the second direction are vertically positioned along the first direction, the opposite ends of these two wiring channels 22 along the first direction can be positioned opposite to the through hole 102 to communicate with each other. In this case, the top wall 111 and the bottom wall 115 can each be provided with through holes 102 at the positions corresponding to the openings of the wiring channels 22. As another example, the opposite ends of the wiring channels 22 extending along the second direction at the bottom of the first sidewall 112 can also be positioned opposite to the through hole 102 to communicate with each other. In this case, the second sidewall 113 and the third sidewall 114 can each be provided with through holes 102 corresponding to the openings of the corresponding wiring channels 22. Therefore, in this embodiment, when through holes 102 are provided on all walls of the receiving groove 110 except for the top wall 111, it is more conducive to wires passing into or out of the wiring groove 22 to meet the wiring and routing needs of different electrical components.

[0049] Along the first direction, the receiving groove 110 also includes a bottom wall 115 away from the top wall 111, and the control box also includes a grounding assembly 30, which includes a conductive element 31 and an insulating mounting base 32. The conductive element 31 is mounted on the bottom wall 115 through the insulating mounting base 32, and there are mounting gaps between the conductive element 31 and the mounting component 21 and the wiring groove 22. Thus, in this embodiment, the grounding conductive element 31 is mounted on the bottom wall 115 of the mounting cavity 101, so that the electrical components in the mounting cavity 101 can achieve the secondary grounding requirement with the shortest distance. The multiple grounding wires between the electrical components and the conductive element 31 do not need to pass through the mounting cavity 101 to achieve grounding, further reducing the complexity of the overall structure of the control box and making the control box more neat and beautiful. Moreover, while the grounding component 30 makes full use of the installation space of the bottom wall 115, the installation gap between the conductive component 31 and the mounting component 21 and the wiring trough 22 can also improve electrical safety, and will not bring electrical safety hazards to the conductive component 31, wires and electrical components, and make the space utilization of the control box higher.

[0050] The conductive element 31 in this embodiment may include a copper busbar, the length of which extends along a third direction. Multiple terminals may be provided on the copper busbar to meet the grounding requirements of a corresponding number of electrical components. The insulating mounting base 32 may include at least two, which are spaced apart along a third direction and fixed between the copper busbar and the bottom wall 115, thereby improving the connection strength and stability between the copper busbar and the bottom wall 115.

[0051] In this embodiment, the housing 11 is an integrally formed structure by bending sheet metal. Therefore, there is no need to open a mold to manufacture the housing 11, which saves the production cost of the control box and the amount of welding of the control box, reduces the processing time of the control box housing 11, and improves production efficiency.

[0052] The control box in this embodiment also includes an energy storage system management unit 40 and / or a temperature controller 50. The energy storage system management unit 40 includes a first display screen 41, which is mounted on the door panel 12 with the first display screen 41 located on the outside of the door panel 12 away from the mounting cavity 101. The temperature controller 50 includes a second display screen 51, which is mounted on the door panel 12 with the second display screen 51 located on the outside of the door panel 12 away from the mounting cavity 101. Therefore, various data can be monitored and collected in real time without opening the door panel 12.

[0053] When there are two door panels 12, the Energy Storage System Management Unit 40 (ESMU) and the temperature controller 50 can be installed on the same door panel 12 to make the overall structure of the control box more compact. Of course, in some embodiments, the Energy Storage System Management Unit 40 and the temperature controller 50 can also be installed on different door panels 12. Typically, since the Energy Storage System Management Unit 40 and the temperature controller 50 can communicate with each other via a communication cable (such as a 485 communication cable), a cable tray 22 for storing and fixing the communication cable can also be provided on the inner wall surface of the door panel 12 near the mounting cavity 101, thereby further improving the neatness of the communication cable and other wires connecting the Energy Storage System Management Unit 40 and the temperature controller 50 on the door panel.

[0054] The control box in this embodiment also includes a disassembly assembly 60, which includes a mounting plate 61 and a connecting seat 62. The mounting plate 61 is detachably mounted to the inner wall of the mounting cavity 101 via the connecting seat 62. The mounting component 21 and the wiring trough 22 can both be detachably mounted on the mounting plate 61. The mounting component 21 and the wiring trough 22 can be detachably mounted on the mounting plate 61 using at least one type of fastener such as bolts, studs, screws, or nuts. Thus, in this embodiment, the mounting component 21 and the wiring trough 22 are mounted on the mounting plate 61 inside the mounting cavity 101. When maintaining electrical components or when it is necessary to add or remove electrical components, it is convenient to replace and disassemble the mounting component 21 and the wiring trough 22, which improves the maintenance flexibility of the control box and also improves the structural strength of the assembled mounting assembly 20 and the box body 11.

[0055] Secondly, given that installing the mounting components 21 and the wiring trough 22 requires drilling numerous mounting holes, this embodiment uses drilling holes in the mounting plate 61 to install the mounting components 20. This avoids drilling numerous holes directly in the enclosure 11, preventing damage to the enclosure 11 or reducing its overall aesthetics. Only a small number of holes for mounting connectors 62 are needed on the enclosure 11. Each mounting plate 61 can be equipped with multiple connectors 62, and the number of connectors 62 can not exceed five (e.g., one of two, three, or four is sufficient). This further reduces the number of holes drilled in the enclosure 11, improving the structural strength and aesthetics of the enclosure 11.

[0056] As can be seen from the above, in this embodiment, the control box 11 can be entirely made of sheet metal bending, eliminating the need for mold making and saving costs. The energy storage system management unit 40 and the temperature controller 50 can be installed on the door panel 12, allowing for convenient real-time monitoring and collection of data from the battery clusters in the battery compartment without opening the door.

[0057] Secondly, mounting components 20 are installed on the four inner walls of the control box, except for the top wall 111. The installation gap between the guide rail 211 and the wiring trough 22 of the mounting components 20 can accommodate the installation of most terminal-type electrical components on the guide rail 211. The waist hole provided in the top wall 111 not only meets the wiring requirements but also facilitates heat dissipation of the control box, meeting the electrical design safety and heat dissipation requirements, and achieving extremely high space utilization. The grounding component 30 is designed to be installed inside the control box, conveniently meeting the secondary grounding requirements of the internal electrical components and reducing the complexity of the wiring layout. The mounting components 20 around the box 11 are detachably fixed to the box 11 by bolting (such as bolt connection). After the guide rail 211 and wiring trough 22 are fixed to the mounting plate 61, the overall structural strength of the box 11 is high, and it also meets a certain aesthetic requirement.

[0058] The second embodiment of this utility model also provides an energy storage device, which includes a control box. The structure of the control box is described in the first embodiment and will not be repeated here.
