Description

Technical Field

[0001] This application relates to the field of high-voltage electrical equipment technology, specifically to electrical control devices and containerized energy storage systems. Background Technology

[0002] In current energy storage systems, the electronic control device serves as a relay device that connects to external power input and is used to output power to users.

[0003] In related technologies, in order to achieve safety protection for the circuit, the electrical control device is equipped with multiple sets of protection elements. The components inside each set of protection elements are far apart, and each protection device needs to be connected to a grounding wire, which is connected to the grounding wire of the electrical control device. This results in complicated wiring connections, which in turn affects the rationality of the internal layout of the electrical control device and also leads to lower safety of the electrical control device. Summary of the Invention

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] In current energy storage systems, the electronic control device serves as a relay device that connects to external power input and is used to output power to users.

[0033] In related technologies, to achieve circuit safety protection, the electrical control device is equipped with multiple sets of protective elements. The components within each set of protective elements are far apart, and each protective device needs to be connected to a grounding wire, which is then connected to the grounding wire of the electrical control device. This results in complex wiring connections, affecting the rationality of the internal layout of the electrical control device. Furthermore, when high temperatures are generated inside the electrical control device, the performance of the protective elements may deteriorate or they may trigger falsely. Replacing protective elements on-site is unsafe and carries the risk of accidentally contacting other live parts.

[0034] In related technologies, the electrical control devices still have the following problems: 1. Fuse and surge protector lack a coordinated protection mechanism, resulting in low reliability of their protection coordination. When the surge protector deteriorates and fails, the fuse cannot quickly disconnect the fault circuit or report system fault information, leading to overvoltage protection failure or malfunction, threatening system safety. 2. High-voltage wiring harnesses are crisscrossed and tangled, with insufficient creepage distance, posing a short-circuit risk. 3. High-voltage and low-voltage wiring harnesses run in parallel, easily generating high-frequency interference coupling, leading to communication interference.

[0035] The following is combined Figures 1 to 13 This describes an embodiment of the present application.

[0036] According to embodiments of this application, in one aspect, an electronic control device is provided, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes: a first mounting beam 2, a second mounting beam 6, multiple sets of protective elements 29, and a conductive plate 7. The first mounting beam 2 and the second mounting beam 6 are spaced apart along the first direction Z. The multiple sets of protective elements 29 are fixed on the first mounting beam 2. Each set of protective elements 29 includes an adjacently arranged fuse 3 and a surge protector 4, and the output terminal of the fuse 3 and the input terminal of the surge protector 4 are connected. The conductive plate 7 is fixed on the second mounting beam 6. The grounding terminal 402 of the surge protector 4 in the multiple sets of protective elements 29 is connected to the conductive plate 7, and the conductive plate 7 is used for grounding.

[0037] In this embodiment, such as Figure 1, Figure 2 and Figure 4 As shown, each set of protective elements 29 includes adjacent fuses 3 and surge protectors 4, and multiple sets of protective elements 29 are fixed on the first mounting beam 2. Multiple fuses 3 and multiple surge protectors 4 are alternately arranged on the first mounting beam 2. The grounding terminal 402 of the surge protector 4 is connected to the conductive plate 7, which is grounded. Each set of fuses 3 and surge protectors 4 forms an electrical branch, and multiple sets of electrical branches can be formed. The multiple sets of protective elements 29 fixed on the first mounting beam 2 allow for a more orderly arrangement of the protective elements 29. Connecting the grounding terminal 402 of the surge protectors 4 uniformly to the conductive plate 7 establishes an equipotential bonding system, eliminating potential differences and providing a low-impedance discharge path for surge current, ensuring the stable operation of the entire energy storage system, preventing equipment damage, and ensuring personal safety.

[0038] The functional zones of the protection element 29 are isolated from the safety of the operators. The reasonable spatial arrangement of the protection element 29, away from the bottom grounding bar 9, increases the ventilation and heat dissipation path and prevents the performance of the protection element 29 from deterioration or false triggering caused by high temperature. In addition, it helps on-site personnel to safely replace the protection element 29 (fuse 3 and surge protector 4) and prevents accidental contact with other live parts.

[0039] In one embodiment, such as Figure 10 As shown, it also includes a snap-fit ​​plate 27. The first mounting beam 2 is provided with a first surface 201. The snap-fit ​​plate 27 is provided on the first surface 201 of the first mounting beam 2. The fuse 3 and the surge protector 4 are both provided with snap-fit ​​grooves 28. The fuse 3 and the surge protector 4 are snapped into the snap-fit ​​plate 27 through the snap-fit ​​grooves 28.

[0040] In this embodiment, such as Figure 11 As shown, the first surface 201 of the first mounting beam 2 is the mounting surface of the protective element 29. The snap-fit ​​plate 27 is connected to the first surface 201 of the first mounting beam 2, specifically by means of bolts, welding, etc. The slots on the fuse 3 and surge protector 4 snap into the snap-fit ​​plate 27, which can quickly connect the fuse 3 and surge protector 4 to the first mounting beam 2, and also facilitate the disassembly of the fuse 3 and surge protector 4.

[0041] In one embodiment, such as Figure 10 As shown, it also includes a locking assembly 26, a snap-fit ​​plate 27 having a first side 2701 and a second side 2702 arranged opposite to each other, a snap-fit ​​groove 28 of the fuse 3 and the surge protector 4 snaps into the first side 2701, and the locking assembly 26 locks the fuse 3 and the surge protector 4 in place at the second side 2702.

[0042] In this embodiment, such as Figure 10As shown, the snap-fit ​​plate 27 is provided with a first side portion 2701, a middle portion and a second side portion 2702 along the first direction Z. The middle portion protrudes from its plate surface to form a protrusion 2703. The protrusion 2703 is connected to the first surface 201 of the first mounting beam 2. Specifically, the protrusion 2703 is provided with multiple through holes 2704. The protrusion 2703 is arranged facing the first mounting beam 2. The protrusion 2703 is connected to the first mounting beam 2 by bolts and through holes 2704. At the same time, due to the presence of the protrusion 2703, there is a certain distance between the first side portion 2701 and the second side portion 2702 and the first mounting beam 2, which facilitates the snap-fit ​​of the fuse 3 and the surge protector 4 to the first side portion 2701. The locking assembly 26 locks the fuse 3 and the surge protector 4 to the second side portion 2702.

[0043] Specifically, such as Figure 10 As shown, the locking assembly 26 can be a wedge plate. A first gap is provided between the surge protector 4 and the fuse 3 and the second side 2702. The wedge plate is inserted into the first gap to lock the second side 2702 with the surge protector 4 and the fuse 3.

[0044] In one embodiment, such as Figure 11 and Figure 12 As shown, the first mounting beam 2 is provided with a second surface 202, and a plurality of first connection holes are provided on the second surface 202. The plurality of first connection holes are arranged at intervals along the length direction of the first mounting beam 2. The feedback harness 25 between the surge protector 4 and the fuse 3 is fixed on the second surface 202 of the first mounting beam 2 through the fastener 21 and the first connection holes.

[0045] In this embodiment, such as Figure 11 and Figure 12 As shown, the fastener 21 is fixed on the first connecting hole. The fastener 21 is also connected to the detection harness 31, which restricts the detection harness 31 on the first mounting beam 2, making the detection harness 31 more regular.

[0046] Specifically, such as Figure 11 As shown, the first mounting beam 2 is a U-shaped beam, with the outer side of the bottom of the U-shaped beam being the first surface 201 and the side of the bottom of the U-shaped beam being the second surface 202.

[0047] Specifically, the detection harness 31 can be a wire harness or a copper busbar.

[0048] Specifically, such as Figure 11 and Figure 12 As shown, the fixing member 21 can be a fixing cable tie or a cedar-shaped fixing head. The cedar-shaped fixing head has a fixing part 2101 and a cable tie 2102. The fixing part 2101 is connected to the first connecting hole, and the cable tie 2102 is used to fix the detection wire harness 31.

[0049] In one embodiment, such as Figure 3 , Figure 4 and Figure 6 As shown, it also includes a third mounting beam 11 and a connecting row assembly 12. The third mounting beam 11 is disposed below the first mounting beam 2 and the second mounting beam 6 along the first direction Z. The connecting row assembly 12 is disposed on the third mounting beam 11. The connecting row assembly 12 is connected to the fuse 3 through the second conductive connector 13. The connecting row assembly 12 is adapted to be connected to the battery cluster 15 through the third conductive connector 14.

[0050] In this embodiment, the connecting bus assembly 12 can be connected to the battery cluster 15 through the third conductive connector 14, and the connecting bus assembly 12 is connected to the fuse 3 through the second conductive connector 13. The connecting bus assembly 12 serves as a connection medium between the battery cluster 15 and the fuse 3. The connecting bus assembly 12 has a large connection area, which facilitates connection with multiple conductive connectors.

[0051] Specifically, such as Figure 6 As shown, the second conductive connector 13 includes a positive electrode harness 1301 and a negative electrode harness 1302.

[0052] In one embodiment, such as Figure 6 As shown, the third mounting beam 11 includes a positive busbar mounting beam 1101 and a negative busbar mounting beam 1102; The connector assembly 12 includes multiple positive connectors 1204 and multiple negative connectors 1205. The multiple positive connectors 1204 are spaced apart on the positive busbar mounting beam 1101, and the multiple negative connectors 1205 are spaced apart on the negative busbar mounting beam 1102. The positive connectors 1204 are connected to the positive input terminal of the fuse 3 through the positive wire harness 1301, and the negative connectors 1205 are connected to the negative input terminal of the fuse 3 through the negative wire harness 1302. The positive connectors 1204 and the negative connectors 1205 are adapted to be connected to the battery cluster 15 through the third conductive connector 14.

[0053] In this embodiment, such as Figure 2 , Figure 3 and Figure 6As shown, multiple fuses 3 and multiple surge protectors 4 are alternately arranged on the first mounting beam 2, and adjacent fuses 3 and surge protectors 4 form a group. Each fuse 3 has a first positive input terminal 302, a first positive output terminal, a first negative input terminal 303, and a first negative output terminal. Each surge protector 4 has a second positive input terminal 403, a second negative input terminal 404, and a grounding terminal 402. The first positive input terminal 302 and the first negative input terminal 303 of the fuse 3 are respectively connected to the positive connection bar 1204 and the negative connection bar 1205. The first positive output terminal of the fuse 3... The output terminal and the first negative output terminal are respectively connected to the second positive input terminal 403 and the second negative input terminal 404 of the surge protector 4. The grounding terminal 402 of the surge protector 4 is connected to the conductive plate 7, and the conductive plate 7 is grounded, thus forming an electrical branch. The fuse 3 and the surge protector 4 are arranged adjacent to each other, and the layout of the fuse 3 and the surge protector 4 is more reasonable. The first conductive connector 5 between the fuse 3 and the surge protector 4 can be a smaller conductive connector, which reduces the space occupied by the first conductive connector 5 and provides more installation space for the fuse 3, the surge protector 4 and other electrical components.

[0054] Specifically, the electrical branch includes the circuit formed by the first positive input terminal 302 of the fuse 3, the first positive output terminal of the fuse 3, the second positive input terminal 403 of the surge protector 4, the grounding terminal 402 of the surge protector 4, and the conductive plate 7, as well as the circuit formed by the first negative input terminal 303 of the fuse 3, the first negative output terminal of the fuse 3, the second negative input terminal 404 of the surge protector 4, the grounding terminal 402 of the surge protector 4, and the conductive plate 7.

[0055] Multiple sets of fuses 3 and surge protectors 4 form multiple electrical branches, such as Figure 2 As shown, the conductive plate 7 is disposed on the second mounting beam 6 and is parallel to the first mounting beam 2. Therefore, the grounding terminal 402 of the surge protector 4 is at the same distance from the second mounting beam 6, which facilitates connection.

[0056] Specifically, such as Figure 2 As shown, the grounding terminal 402 of the surge protector 4 is connected to the conductive plate 7.

[0057] Specifically, such as Figure 2 As shown, multiple first conductive connectors 5 are used to connect the first positive output terminal of the fuse 3 and the second positive input terminal 403 of the surge protector 4, and to connect the first negative output terminal of the fuse 3 and the second negative input terminal 404 of the surge protector 4.

[0058] In one embodiment, a plurality of positive electrode connection bars 1204 and a plurality of negative electrode connection bars 1205 are arranged in a staggered manner along a first direction Z.

[0059] In this embodiment, such as Figure 3 and Figure 5 As shown, the positive terminal connector 1204 and the negative terminal connector 1205 are staggered, which facilitates the connection of the positive terminal wire harness 1301 and the third conductive connector 14 on the positive terminal connector 1204, and the connection of the negative terminal wire harness 1302 and the third conductive connector 14 on the negative terminal connector 1205. During the connection process, interference between the positive terminal wire harness 1301, the negative terminal wire harness 1302 and the third conductive connector 14 is prevented.

[0060] In one embodiment, such as Figure 1 As shown, a first insulating plate 16 is provided between two adjacent positive terminal connection bars 1204 on the positive terminal busbar mounting beam 1101; And / or, a second insulating plate 20 is provided between two adjacent negative terminal connecting blocks 1205 on the negative terminal bus mounting beam 1102.

[0061] In this embodiment, such as Figure 1 and Figure 5 As shown, a first insulating plate 16 is provided between two adjacent positive electrode connection bars 1204. The first insulating plate 16 extends along the second direction Y, isolating the two adjacent positive electrode connection bars 1204 and increasing the creepage distance between the two positive electrode connection bars 1204. The larger the creepage distance, the more difficult it is to generate an electric arc between the two adjacent positive electrode connection bars 1204.

[0062] Similarly, a second insulating plate 20 is provided between two adjacent negative electrode connection bars 1205. The second insulating plate 20 extends along the second direction Y, isolating the two adjacent negative electrode connection bars 1205 and increasing the creepage distance between the two negative electrode connection bars 1205. The larger the creepage distance, the more difficult it is to generate an electric arc between the two adjacent negative electrode connection bars 1205.

[0063] It should be noted that creepage distance refers to the shortest path distance measured along the surface of the insulating material between the two positive terminal connectors 1204.

[0064] In one embodiment, such as Figure 13 As shown, a plurality of first mounting holes 1103 are provided on the positive busbar mounting beam 1101. The plurality of first mounting holes 1103 are arranged at intervals along the length direction of the positive busbar mounting beam 1101. The positive wire harness 1301 between the positive connecting busbar 1204 and the fuse 3 is fixed on the positive busbar mounting beam 1101 through the first mounting holes 1103 and the first wire harness locking member. And / or, the negative busbar mounting beam 1102 is provided with a plurality of second mounting holes, which are arranged at intervals along the length of the negative busbar mounting beam 1102. The negative wire harness 1302 between the negative connection bar 1205 and the fuse 3 is fixed to the negative busbar mounting beam 1102 through the second mounting holes and the second wire harness locking member.

[0065] In this embodiment, the first wire harness locking member and the second wire harness locking member can be a fixing cable tie or a cedar-shaped fixing head. The cedar-shaped fixing head has a fixing part 2101 and a cable tie 2102. The fixing part 2101 is connected to the first mounting hole 1103 or the second mounting hole. The cable tie 2102 is used to fix the positive wire harness 1301 or the negative wire harness 1302.

[0066] In some embodiments, such as Figure 6 As shown, both the positive terminal connector 1204 and the negative terminal connector 1205 are rectangular plates with chamfered edges. Both the positive terminal connector 1204 and the negative terminal connector 1205 are provided with a first wiring hole and a second wiring hole. The first wiring hole is the first connection end 1201, and the second wiring hole is the second connection end 1202. The first connection end 1201 and the second connection end 1202 are respectively connected to the positive terminal harness 1301 and the negative terminal harness 1302. The positive terminal harness 1301 and the negative terminal harness 1302 are connected to the first connection end 1201 and the second connection end 1202 by bolts and nuts.

[0067] In some embodiments, such as Figure 6 As shown, both the positive terminal connector 1204 and the negative terminal connector 1205 are copper plates. The copper plates can be made of pure copper or copper plates with an outer tin plating. The outer tin plating of the copper plate can prevent copper oxidation and maintain its conductivity. The edges of the copper plates are rounded.

[0068] In some embodiments, such as Figure 3 , Figure 6 and Figure 8 As shown, the positive terminal connector 1204 and the negative terminal connector 1205 are also provided with two third wiring holes, which are third connection terminals 1203. The two third connection terminals 1203 are used to connect to the user terminal 23 through the user harness 19.

[0069] In some embodiments, such as Figure 1 As shown, there are twelve positive connection bars 1204 and twelve negative connection bars 1205. The first positive input terminal 302 and the first negative input terminal 303 of a fuse 3 are connected to the positive connection bar 1204 and the negative connection bar 1205 respectively.

[0070] In one embodiment, such as Figure 1As shown, the positive busbar mounting beam 1101 has a first end and a second end arranged opposite to each other. A portion of the positive electrode harness 1301 on the positive busbar mounting beam 1101 near the first end extends toward the first end of the positive busbar mounting beam 1101, and a portion of the positive electrode harness 1301 on the positive busbar mounting beam 1101 near the second end extends toward the second end of the positive busbar mounting beam 1101. And / or, the negative busbar mounting beam 1102 has a first end and a second end arranged opposite to each other, a portion of the negative wire harness 1302 on the negative busbar mounting beam 1102 near the first end extends toward the first end of the negative busbar mounting beam 1102, and a portion of the negative wire harness 1302 on the negative busbar mounting beam 1102 near the second end extends toward the second end of the negative busbar mounting beam 1102.

[0071] In this embodiment, such as Figure 1 As shown, the positive electrode harness 1301 is divided into two parts. The positive electrode harness 1301 near the first end of the positive electrode busbar mounting beam 1101 extends toward its first end and converges, and then connects to the fuse 3 in a unified manner along the first direction Z upward. The positive electrode harness 1301 near the second end of the positive electrode busbar mounting beam 1101 extends toward its second end and converges, and then connects to the fuse 3 in a unified manner along the first direction Z upward. The negative electrode harness 1302 is divided into two parts. The negative electrode harness 1302 near the first end of the negative electrode busbar mounting beam 1102 extends towards its first end and converges, then connects uniformly to the fuse 3 in the first direction Z upwards. The negative electrode harness 1302 near the second end of the negative electrode busbar mounting beam 1102 extends towards its second end and converges, then connects uniformly to the fuse 3 in the first direction Z upwards. The positive electrode harness 1301 and negative electrode harness 1302 are organized to improve the harness layout, enhance the neatness and overall integrity of the harness layout, and facilitate future maintenance and replacement.

[0072] In one embodiment, such as Figure 13 As shown, multiple first mounting holes 1103 are provided in two rows, and the two rows of first mounting holes 1103 are staggered along the length direction of the positive busbar mounting beam 1101. And / or, multiple second mounting holes are provided in two rows, with the two rows of second mounting holes staggered along the length of the negative busbar mounting beam 1102.

[0073] In this embodiment, such as Figure 13 As shown, the first mounting holes 1103 are arranged in two rows, and the two rows of first mounting holes 1103 are staggered. When fixing the positive electrode harness 1301, multiple positive electrode harnesses 1301 can be connected in a staggered manner to prevent interference between positive electrode harnesses 1301 extending in the same direction, and at the same time facilitate the connection of positive electrode harnesses 1301.

[0074] The second mounting holes are arranged in two rows, and the two rows of second mounting holes are staggered. When fixing the negative electrode harness 1302, multiple negative electrode harnesses 1302 can be connected in a staggered manner to prevent interference between negative electrode harnesses 1302 extending in the same direction, and at the same time facilitate the connection of negative electrode harnesses 1302.

[0075] In one embodiment, such as Figure 1 and Figure 4 As shown, there are two positive busbar mounting beams 1101 and two negative busbar mounting beams 1102. The two positive busbar mounting beams 1101 and the two negative busbar mounting beams 1102 are staggered along the first direction Z; the two positive busbar mounting beams 1101 and the two negative busbar mounting beams 1102 are staggered along the second direction Y. The second direction Y is perpendicular to the first direction Z.

[0076] In this embodiment, two positive busbar mounting beams 1101 and two negative busbar mounting beams 1102 are staggered along the first direction Z, so that the positive connection bar 1204 and the negative connection bar 1205 are misaligned along the first direction Z, facilitating the connection of the positive wire harness 1301, the negative wire harness 1302, and the third conductive connector 14 to the positive connection bar 1204 and the negative connection bar 1205. The two positive busbar mounting beams 1101 and the two negative busbar mounting beams 1102 are also staggered along the second direction Y, meaning the positive connection bar 1204 and the negative connection bar 1205 are also misaligned along the second direction Y, facilitating the connection of the user wire harness 19 to the positive connection bar 1204 and the negative connection bar 1205, and simplifying installation for workers.

[0077] In this embodiment, such as Figure 1 and Figure 5 As shown, the two positive busbar mounting beams 1101 and the two negative busbar mounting beams 1102 have a second gap in the second direction Y. Parts of the positive wire harness 1301 and part of the negative wire harness 1302 extend along the first direction Z and can pass through the second gap, facilitating wire harness connection. Simultaneously, the positive wire harness 1301 and part of the negative wire harness 1302 do not obstruct each other in the second direction Y, facilitating disassembly, assembly, and inspection. The positive wire harness 1301, the negative wire harness 1302, and the third conductive connector 14 are all high-voltage wire harnesses. The high-voltage wire harnesses generally extend along the first direction Z to prevent cross-entanglement.

[0078] For example, the positive electrode harness 1301 connected to the positive electrode connection bar 1204 on the lower positive electrode busbar mounting beam 1101 has the portion of the positive electrode harness 1301 near the first end of the positive electrode busbar mounting beam 1101 extending toward the first end of the positive electrode busbar mounting beam 1101, and the portion of the positive electrode harness 1301 near the second end extending toward the second end of the positive electrode busbar mounting beam 1101; the positive electrode harness 1301 connected to the positive electrode connection bar 1204 on the upper positive electrode busbar mounting beam 1101 extends along the first direction Z and passes through the second gap to connect with the fuse 3; similarly, the portion of the positive electrode harness 1301 connected to the positive electrode connection bar 1204 on the upper positive electrode busbar mounting beam 1101 extends along the first direction Z and passes through the second gap to connect with the fuse 3; similarly, the portion of the positive electrode harness 1301 near the second end of the positive electrode busbar mounting beam 1101 extends toward the second end of the positive electrode busbar mounting beam 1101. The negative electrode harness 1302 connected to the negative electrode connection bar 1205 on the lower negative electrode busbar mounting beam 1102 has a portion of the negative electrode harness 1302 near the first end of the negative electrode busbar mounting beam 1102 extending toward the first end of the negative electrode busbar mounting beam 1102, and a portion of the negative electrode harness 1302 near the second end of the negative electrode busbar mounting beam 1102 extending toward the second end of the negative electrode busbar mounting beam 1102. The negative electrode harness 1302 connected to the negative electrode connection bar 1205 on the upper negative electrode busbar mounting beam 1102 extends along the first direction Z and passes through the second gap to connect with the fuse 3.

[0079] In some embodiments, the first insulating plate 16 includes a first plate and a second plate, wherein the first plate and the second plate are perpendicular to each other, the first plate is located between adjacent positive electrode connection rows 1204, and the second plate is parallel to the positive electrode connection rows 1204 and is provided with a wire binding hole. When the positive electrode harness 1301 or negative electrode harness 1302 located below the first insulating plate 16 extends upward, it can be fixed to the wire binding hole of the first plate of the first insulating plate 16 by the wire harness fixing member 21. Similarly, the second insulating plate 20 includes a third plate and a fourth plate, wherein the third plate and the fourth plate are perpendicular to each other, the third plate is located between adjacent negative electrode connection rows 1205, and the fourth plate is parallel to the negative electrode connection rows 1205 and is provided with a wire binding hole. When the positive electrode harness 1301 or negative electrode harness 1302 located below the second insulating plate 20 extends upward, it can be fixed to the wire binding hole of the third plate of the second insulating plate 20 by the wire harness fixing member 21.

[0080] In some embodiments, the mounting frame 1 is divided into a first region and a second region along the first direction Z, the first mounting beam 2 and the second mounting beam 6 are disposed in the first region, and a plurality of third mounting beams 11 are disposed in the second region. In some embodiments, such as Figure 5 As shown, along the first direction Z, the mounting frame 1 has a seven-layer structure inside, which are the first layer, second layer, third layer, fourth layer, fifth layer, sixth layer and seventh layer from top to bottom.

[0081] The first and third layers are where the first installation beam 2 is located.

[0082] The second layer is provided with a second mounting beam 6, and a conductive plate 7 is provided on the second mounting beam 6. The conductive plate 7 is a copper busbar and is individually connected to the grounding terminal 402 of the twelve surge protectors 4 in the first and third layers.

[0083] The fourth to seventh layers include two positive busbar mounting beams 1101 and two negative busbar mounting beams 1102. Each positive busbar mounting beam 1101 has six positive connection bars 1204, and each negative busbar mounting beam 1102 has six negative connection bars 1205. Figure 6 and Figure 8 As shown, from top to bottom, the positive busbar mounting beam 1101 and the negative busbar mounting beam 1102 are arranged alternately.

[0084] In one embodiment, the second mounting beam 6 is provided with a first surface 201, and a conductive plate 7 is connected to the first surface 201 of the second mounting beam 6. The conductive plate 7 is elongated, and the projection of the conductive plate 7 along the direction perpendicular to the first surface 201 of the second mounting beam 6 is located within the first surface 201 of the second mounting beam 6.

[0085] In this embodiment, the conductive plate 7 is used to connect the grounding terminals 402 of multiple surge protectors 4, reducing the use of wiring harnesses. By setting the conductive plate 7 to be an elongated plate shape that adapts to the second mounting beam 6, the distance between each surge protector 4 and the conductive plate 7 is relatively close, which helps to shorten the connection path. Furthermore, the projection of the conductive plate 7 along the first surface 201 of the second mounting beam 6 is located on the second mounting beam 6, which can prevent the conductive plate 7 from touching other devices or wiring harnesses, thus improving safety.

[0086] In one embodiment, the conductive plate 7 is provided with multiple fixing holes, and the grounding terminal 402 of the surge protector 4 is connected to the conductive plate 7 through the fixing holes.

[0087] In one embodiment, at least two first mounting beams 2 are provided, and the two first mounting beams 2 are spaced apart along the first direction Z. Each first mounting beam 2 is provided with multiple sets of protective elements 29, and the second mounting beam 6 is provided between the two first mounting beams 2.

[0088] In this embodiment, the second mounting beam 6 is positioned between the two first mounting beams 2, and can simultaneously connect the grounding terminals 402 of the surge protectors 4 on both rows of first mounting beams 2. This results in a simpler structure and a smaller footprint.

[0089] Specifically, such as Figure 3 As shown, the two first mounting beams 2 and the second mounting beam 6 are arranged in parallel along the first direction Z. The second mounting beam 6 is equidistant from the two adjacent first mounting beams 2, which can reduce the difference in the connection length between the grounding terminal 402 of the surge protector 4 on the two first mounting beams 2 and the conductive plate 7.

[0090] In some embodiments, such as Figure 1 , Figure 3 and Figure 8 As shown, each first mounting beam 2 is equipped with six fuses 3 and six surge protectors 4. An adjacent fuse 3 and a surge protector 4 form a group, and the fuses 3 and surge protectors 4 on the two first mounting beams 2 form twelve electrical branches. In one embodiment, the fuse 3 is provided with a first detection terminal 301, and the surge protector 4 is provided with a second detection terminal 401. The first detection terminal 301 of the fuse 3 in the protection element 29 is connected in series with the second detection terminal 401 of the surge protector 4.

[0091] In this embodiment, such as Figure 2 As shown, the fuse 3 is provided with a first detection terminal 301, and the surge protector 4 is provided with a second detection terminal 401. In a set of fuse 3 and surge protector 4, the first detection terminal 301 and the second detection terminal 401 are connected in series through a detection harness 31. The first detection terminal 301 and the second detection terminal 401 are adapted to be connected to the control module 8. The control module 8 detects the fuse 3 and the surge protector 4.

[0092] In this embodiment, such as Figure 2 and Figure 9 As shown, the control module 8 is equipped with multiple positive terminals 801 and negative terminals. One of the first detection terminals 301 of the fuse 3 and the second detection terminal 401 of the surge protector 4 in a group are connected to a positive terminal 801 and the other to a negative terminal 802. This is used to detect each group of fuses 3 and surge protectors 4, enabling timely detection of faulty fuses 3 and surge protectors 4, including short circuits, open circuits, or overheating. A collaborative protection mechanism is established between the fuses 3 and surge protectors 4, resulting in high reliability. Fuse 3 and surge protectors 4 in a group are connected in series, while multiple groups of fuses 3 and surge protectors 4 are connected in parallel. When a surge protector 4 in a group deteriorates and fails, the fuse 3 can quickly disconnect the fault circuit or report system fault information, improving system safety.

[0093] Specifically, such as Figure 1 , Figure 2 and Figure 9As shown, multiple sets of fuses 3 and surge protectors 4 are connected in parallel with the positive terminal 801 and negative terminal 802 of the control module 8 through a feedback harness 25. Multiple detection harnesses 31 are connected in parallel with the feedback harness 25. The first detection terminal 301 and the second detection terminal 401 are normally closed contacts. When a surge protector 4 or fuse 3 in a set fails, the first detection terminal 301 and the second detection terminal 401 become normally open contacts, disconnecting the connection. The control module 8 triggers an alarm. One end of the feedback harness 25 is connected to a feedback terminal 24, which is connected in parallel with the positive terminal 801 and the negative terminal 802.

[0094] In one embodiment, such as Figures 1 to 3 As shown, it also includes: a mounting frame 1 and a grounding bar 9, with the first mounting beam 2 and the second mounting beam 6 connected to the mounting frame 1; the grounding bar 9 is located at the bottom of one side of the mounting frame 1 and is electrically connected to the conductive plate 7.

[0095] In this embodiment, such as Figures 1 to 3 As shown, the grounding wire 10 is connected to one end of the conductive plate 7. The grounding wire 10 extends along the first direction Z and is located on the left side of the mounting frame 1. The grounding busbar 9 is located at the bottom left side of the mounting frame 1. The conductive plate 7 is connected to the grounding terminals 402 of multiple surge protectors 4 and is connected to the grounding busbar 9 through the grounding wire 10. By connecting the grounding terminals 402 of multiple surge protectors 4 to the grounding busbar 9 through a single grounding wire 10, the wiring harness arrangement in the mounting frame 1 becomes neater.

[0096] In one embodiment, an isolation tube 18 is also provided, which extends along the first direction Z and penetrates the mounting frame 1, and the isolation tube 18 is disposed on one side of the mounting frame 1.

[0097] Secondly, this application also provides a containerized energy storage system, such as Figures 7 to 9 As shown, it includes: an electronic control device and multiple battery clusters 15, the battery clusters 15 being connected to a fuse 3.

[0098] Specifically, the control module 8 is located at the top of the mounting bracket 1, and the control module 8 is connected in parallel with multiple sets of fuses 3 and surge protectors 4; each battery cluster 15 is connected to a high-voltage box 22, and the high-voltage box 22 is connected to each fuse 3; the two ends of the isolation tube 18 are higher than the top of the mounting bracket 1 and lower than the bottom of the mounting bracket 1, respectively, and the fourth conductive connector 30 led out from the control cabinet is suitable for passing through the isolation tube 18 and connecting to the user terminal 23.

[0099] In some embodiments, the control module 8 extends a fourth conductive connector 30, which passes through the mounting bracket 1 via an isolation tube 18 and connects to the user terminal 23. This prevents the fourth conductive connector 30 from running parallel to the positive electrode harness 1301, the negative electrode harness 1302, and the third conductive connector 14, thus avoiding electromagnetic interference. The fourth conductive connector 30 can be a low-voltage communication harness, including 12 branch PCS CAN communication, RS485 communication, and dry contacts. The low-voltage communication harness connecting the control module 8 passes through the isolation tube 18 and connects to the PCS device at the user terminal 23 for inter-device communication.

[0100] It should be noted that the containerized energy storage system includes the electronic control device provided in the embodiments of this application, and therefore includes all the advantages of the electronic control device mentioned above, so it will not be described again.

[0101] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
