Technical Field

[0001] The utility model relates to the technical field of energy storage, and more specifically, to an energy storage control component. Background Art

[0002] The high-voltage box is a core component in the energy storage system. The high-voltage box is equipped with a control circuit for controlling the charging and discharging processes of the battery system. When the voltage of a single battery cell is lower or higher than its threshold during the charging and discharging processes, the high-voltage box can give an early warning or cut off the power supply to protect the battery system, ensuring the safety and stability of the energy storage system. It is widely used in multiple links such as power generation, power transmission, power distribution, and power consumption in the power system.

[0003] In the prior art, a large number of precision electronic components are arranged in the high-voltage box in a disorderly manner.

[0004] However, the space inside the high-voltage box is limited, and the voltage passing through the high-voltage box is relatively high. If a large number of precision electronic components are randomly placed, it is easy to cause mutual interference between electrical components, and even an arc phenomenon may occur between electrical components, resulting in the technical problems of large potential safety hazards and poor reliability in the high-voltage box. Summary of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0006] Therefore, the utility model provides an energy storage control component.

[0007] In view of this, a first aspect of the utility model provides an energy storage control component, which includes: a housing, with a cavity formed inside the housing; a support member, disposed inside the cavity and connected to the housing; and a plurality of electrical components, disposed inside the cavity. The plurality of electrical components include a first electrical component and a second electrical component. The first electrical component is connected to the support member, and the second electrical component is connected to the housing. The first electrical component and the second electrical component are spaced apart in the height direction of the energy storage control component.

[0008] In this technical solution, an energy storage control component is defined. The energy storage control component is connected to the energy storage component and is used to control the charging and discharging operations of the battery module in the energy storage component.

[0009] Specifically, the energy storage control component includes a housing and a plurality of electrical components. The housing forms the outer surface of the energy storage control component. A cavity is enclosed inside the housing. The plurality of electrical components are disposed inside the cavity. The housing can provide positioning and protection for the electrical components, preventing the electrical components from being damaged by external impacts and external pollutants. At the same time, the housing also has insulating properties, which can reduce the probability of leakage problems occurring in the energy storage control component.

[0010] On this basis, the energy storage control component is further provided with a support member. A plurality of electrical components are divided into a first electrical component and a second electrical component according to the distribution area. The first electrical component is connected to the support member, and the first electrical component is arranged on the top of the second electrical component under the support of the support member.

[0011] Setting the support member can realize a two-level spatial layout of multiple electrical components in the cavity, thereby reasonably utilizing the space inside the cavity in the height direction of the energy storage control component and avoiding the random arrangement of multiple electrical components in the cavity. Specifically, the first electrical component is arranged in the upper half space of the cavity under the support of the support member, and the second electrical component is arranged in the lower half space of the cavity, so as to make full use of the space inside the cavity in the height direction for the layout of electrical components.

[0012] It can be seen that by setting the support member to perform a two-layer layout of multiple electrical components, the limited space inside the housing can be fully utilized, the interval between adjacent electrical components can be increased, thereby reducing the probability of interference between electrical components and reducing the probability of arc phenomenon between adjacent electrical components. Furthermore, the technical problems of large safety hazards and poor reliability existing in the related technology are solved, and the technical effects of optimizing the spatial layout of the energy storage control component, reducing the failure rate of the energy storage control component, and improving the safety of the energy storage control component are achieved.

[0013] In addition, the above-mentioned energy storage control component provided by the present utility model may also have the following additional technical features:

[0015] In this technical solution, the support member includes a mounting plate and a bracket. The first electrical component is connected to the mounting plate, and the bracket is connected between the mounting plate and the housing. The bracket is used to fix the mounting plate and the first electrical component on the predetermined mounting position to avoid the dislocation of the mounting plate and the first electrical component on the mounting plate, thereby improving the structural stability of the energy storage control component.

[0016] On this basis, the first electrical component is arranged on the first side of the mounting plate, and the second electrical component is arranged on the second side of the mounting plate, so that the mounting plate can play a role in separating between the first electrical component and the second electrical component, avoiding interference between the first electrical component and the second electrical component, preventing arc phenomenon between the first electrical component and the second electrical component, and further achieving the technical effects of improving the safety and reliability of the electrical component and reducing the failure rate of the electrical component.

[0017] Specifically, the mounting plate can play a role in lifting the first electrical component, so that the first electrical component can stay on the top of the second electrical component.

The first electrical component is fixed to the top of the mounting plate, and the second electrical component is connected to the mounting plate and / or the inner wall of the housing. After assembly, the second electrical component is located between the mounting plate and the bottom wall of the cavity.

[0020] Arranging multiple electrical components in a double layer in the height direction can reasonably utilize the space of the cavity in the height direction, thereby increasing the distance between two adjacent electrical components in the horizontal direction, avoiding interference problems and arc phenomena caused by the two adjacent electrical components being too close, and further achieving the technical effects of optimizing the spatial layout of multiple electrical components, improving the reliability and safety of electrical components, and reducing the failure rate of electrical components.

[0022] In this technical solution, the bracket includes a sheet metal part and a support column.

The support column is connected between the sheet metal part and the mounting plate. The sheet metal part is connected to the inner wall of the cavity. The sheet metal part positions and supports the mounting plate through the support column, so that the first electrical component can be stable above the second electrical component.

[0023] Among them, by setting the sheet metal part, the contact area between the support component and the bottom wall of the cavity can be increased, thereby improving the stability of the support component and preventing the support component from shaking in the cavity. By setting the support column, effective support can be provided for the mounting plate, preventing the mounting plate from tilting or even collapsing. Further achieving the technical effects of improving the structural stability of the support component and improving the positioning accuracy of the first electrical component.

[0024] In some technical solutions of the present utility model, optionally, the number of support columns is multiple, and the multiple support columns are arranged side by side between the mounting plate and the sheet metal part.

[0025] In this technical solution, multiple support columns are provided between the mounting plate and the sheet metal part, and the multiple support columns are arranged side by side between the mounting plate and the sheet metal part to form a support column array for supporting the mounting plate.

[0026] By setting multiple support columns, on the one hand, multi-point support can be provided for the mounting plate to ensure the stability of the mounting plate and avoid the tilting problem of the mounting plate. On the other hand, the multiple support columns can share the weight of the mounting plate and the first electrical component, thereby reducing the probability of stress damage to the support columns, and thus improving the positioning accuracy and positioning stability of the first electrical component.

[0027] Specifically, six support columns are provided between the mounting plate and the sheet metal part. The six support columns are divided into two rows in the width direction of the housing, and each row contains three support columns. The three support columns belonging to the same row are spaced along the length direction of the housing.

[0029] In this technical solution, the first electrical component includes a power supply. Specifically, the voltage of the power supply is 12V, and a power supply control module and a quick-insert plug are provided on the power supply. The first electrical component also includes a fuse, and the fuse includes a main positive fuse and a heating fuse. The first electrical component also includes a relay, and the relay includes a main positive relay, a main negative relay, a heating relay, and a pre-charge relay. The first electrical component also includes a shunt and a current sensor. Specifically, the current sensor is a Hall sensor. The first electrical component also includes a parallel port conversion box and an energy storage converter.

[0030] The second electrical component includes a lightning protection module, a light-emitting component, a circuit breaker, a network port, and a chip. Among them, the light-emitting component is an LED (light emitting diode) lamp. The circuit breaker is fixed on a circuit breaker bracket, and a circuit breaker protective cover is provided outside the circuit breaker. The chip is fixed on a chip bracket.

[0031] Specifically, a first side plate and a second side plate are connected to the outside of the housing. A nameplate is provided on the second side plate, and the parameter information of the energy storage control component is recorded on the nameplate. The first side plate can provide protection for the interfaces on the housing.

[0032] In some technical solutions of the present utility model, optionally, the housing includes: a box body, the box body includes an opening, a cover body, the cover body is flange-connected to the box body, and the cover body covers the opening; a sealing ring, the sealing ring is provided between the cover body and the box body, and the sealing ring is used to seal the gap between the cover body and the box body.

[0033] In this technical solution, the housing includes a box body and a cover body. An opening is provided at the top of the box body, and electrical components can be installed inside the box body through the opening. During subsequent use, users can also maintain and repair the electrical components inside the box body at the opening.

[0034] On this basis, the cover body is covered above the opening, and the cover body and the box body are flange-connected. On the one hand, flange connection has the advantage of being detachable, which can provide convenient conditions for disassembling and assembling electrical components and reduce the difficulty of replacing and maintaining electrical components. On the other hand, flange connection has strong sealing performance, which can reduce the probability of sealing dead angles between the box body and the cover body.

[0035] Wherein, a sealing ring is clamped between the cover body and the box body, and the sealing ring surrounds the periphery of the opening. The sealing ring can fill the gap between the cover body and the box body, thereby sealing the gap between the cover body and the box body to prevent pollutants such as dust and liquid from entering the interior of the box body, reducing the probability of electrical components failing and being damaged due to pollutants, and further achieving the technical effects of improving the sealing performance of the energy storage control component, reducing the failure rate of electrical components, and extending the service life of electrical components.

[0036] In some technical solutions of the present utility model, optionally, the box body includes a top surface, the opening is provided on the top surface, and the sealing ring is press-fitted between the cover body and the top surface; the sealing ring is foam-molded on the cover body.

[0037] In this technical solution, one side of the box body facing the cover body includes a top surface, the opening is opened in the central area of the top surface, and the top surface is flange-connected to the cover body.

[0038] On this basis, the sealing ring is foam-molded on the lower surface of the cover body, and the foam-molded sealing ring is disposed opposite to the top surface. After foaming is completed, the cover body can be covered above the top surface, and the sealing ring is clamped between the end surface under flange connection and the cover body, so that the foam-molded sealing ring deforms under extrusion and fills the gap between the cover body and the top surface through deformation, preventing pollutants from entering the inner side of the box body between the cover body and the top surface, and further achieving the technical effects of improving the sealing reliability of the energy storage control component and reducing the failure rate of electrical components. At the same time, forming the sealing ring by the foaming process can reduce the process complexity of the energy storage control component and is beneficial to reducing the production cost of the energy storage control component.

[0039] In some technical solutions of the present utility model, optionally, the cover body includes through holes, and the energy storage control component further includes: nuts, which are disposed on the top surface, the number of nuts is multiple, and the multiple nuts are distributed around the opening, and the through holes are opposite to the nuts; a connecting component, the connecting component passes through the through holes, and the connecting component is connected to the nuts, and the connecting component is used to press-fit the cover body on the nuts.

[0040] In this technical solution, through holes are provided on the cover body, the number of through holes is multiple, and the multiple through holes are arranged in an array along a loop on the cover body. Correspondingly, nuts are provided on the top surface of the box body, and the number of nuts is the same as the number of through holes. During the assembly process, the multiple through holes and the multiple nuts correspond one by one.

[0041] The energy storage control component further includes a connecting component. The connecting component passes through the cover body through a through hole and is screwed to a nut below the through hole. By connecting multiple groups of through holes and nuts through multiple connecting components respectively, the flange connection between the cover body and the box body can be completed.

[0042] Specifically, during the assembly process, the cover body is initially positioned on the box body first, so that the sealing ring abuts against the top surface and the through hole is aligned with the nut. Then, the cover body is pressed down by inserting the connecting component. During this process, the sealing ring is compressed and deformed until the lower surface of the cover body is assembled with the upper surface of the nut. At this time, the sealing ring deformed under pressure fills the gap between the cover body and the top surface to achieve effective sealing.

[0043] Specifically, in the present application, by cooperating with a sealing ring on the basis of flange connection, the waterproof level of the energy storage control component can be improved to IP67.

[0044] Specifically, the connecting component includes a screw and a bolt.

[0045] In some technical solutions of the present utility model, optionally, in the height direction of the box body, the size range of the nut is: greater than or equal to 1 mm and less than or equal to 3 mm.

[0046] In this technical solution, in the height direction of the box body, the size of the nut is the height of the nut. The height of the nut corresponds to the distance that the nut protrudes from the top surface. After the assembly is completed, the top surface of the nut contacts the bottom surface of the cover body, and this distance corresponds to the height available for accommodating the sealing ring.

[0047] On this basis, the height of the nut needs to be greater than or equal to 1 mm and less than or equal to 3 mm.

[0048] By defining that the height of the nut is greater than or equal to 1 mm, enough layout space can be reserved for the sealing ring to ensure that the cover body can be smoothly pressed above the nut, reducing the sealing assembly difficulty of the energy storage control component.

[0049] By defining that the height of the nut is less than or equal to 3 mm, the gap between the cover body and the top surface can be reduced on the basis of meeting the space layout requirements of the sealing ring, thereby reducing the sealing difficulty of the sealing ring for this gap and improving the sealing effect between the cover body and the box body.

[0050] Specifically, the height of the nut is 2 mm, and the thickness of the sealing ring is greater than the height of the nut to ensure that the sealing ring can be compressed.

Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0060] Next, reference is made to Figures 1 to 3 to describe an energy storage control assembly according to some embodiments of the present utility model.

[0061] As Figure 1 and Figure 2 shown, an embodiment of the present utility model provides an energy storage control component 100, and the energy storage control component 100 includes: a housing 110, and a cavity 1102 is included inside the housing 110; a support member 120, the support member 120 is disposed inside the cavity 1102, and the support member 120 is connected to the housing 110; a plurality of electrical components, the plurality of electrical components are disposed inside the cavity 1102, the plurality of electrical components include a first electrical component 130 and a second electrical component 140, the first electrical component 130 is connected to the support member 120, the second electrical component 140 is connected to the housing 110, and the first electrical component 130 and the second electrical component 140 are spaced apart in the height direction of the energy storage control component 100 ( Figure 1 as indicated by the arrow a in).

[0063] Specifically, the energy storage control component 100 includes a housing 110 and a plurality of electrical components. The housing 110 forms the outer surface of the energy storage control component 100. A cavity 1102 is enclosed inside the housing 110. The plurality of electrical components are disposed inside the cavity 1102. The housing 110 can provide positioning and protection for the electrical components, avoiding damage to the electrical components due to external impacts and external contaminants. At the same time, the housing 110 also has insulation performance, which can reduce the probability of leakage problems occurring in the energy storage control component 100.

[0064] On this basis, the energy storage control component 100 is further provided with a support member 120.

Among them, the first electrical component 130 is connected to the support member 120, and the first electrical component 130 is arranged on top of the second electrical component 140 under the support of the support member 120.

[0065] Setting the support member 120 can realize a two-level spatial layout of a plurality of electrical components in the cavity 1102, thereby rationally utilizing the space inside the cavity 1102 in the height direction of the energy storage control component 100, and avoiding random and irregular arrangement of a plurality of electrical components in the cavity 1102. Specifically, the first electrical component 130 is arranged in the upper half space of the cavity 1102 under the support of the support member 120, and the second electrical component 140 is arranged in the lower half space of the cavity 1102, so as to make full use of the space inside the cavity 1102 in the height direction for electrical component layout.

[0066] It can be seen that by arranging the support member 120 to double - layer layout multiple electrical components, the limited space inside the housing 110 can be fully utilized, the interval between adjacent electrical components can be increased, thereby reducing the probability of mutual interference between electrical components, reducing the probability of arc phenomenon between adjacent electrical components, and further solving the technical problems of large potential safety hazards and poor reliability in the related art, achieving the technical effects of optimizing the spatial layout of the energy storage control component 100, reducing the failure rate of the energy storage control component 100, and improving the safety of the energy storage control component 100.

The bracket 124 is used to fix the mounting plate 122 and the first electrical component 130 thereon at a predetermined mounting position, avoiding the dislocation of the mounting plate 122 and the first electrical component 130 on the mounting plate 122, thereby improving the structural stability of the energy storage control component 100.

[0069] On this basis, the first electrical component 130 is arranged on the first side of the mounting plate 122, and the second electrical component 140 is arranged on the second side of the mounting plate 122, enabling the mounting plate 122 to play a separating role between the first electrical component 130 and the second electrical component 140, avoiding mutual interference between the first electrical component 130 and the second electrical component 140, preventing arc phenomenon between the first electrical component 130 and the second electrical component 140, and further achieving the technical effects of improving the safety and reliability of electrical components and reducing the failure rate of electrical components.

The sheet metal part 1242 positions and supports the mounting plate 122 through the support column 1244, so that the first electrical component 130 can be stably above the second electrical component 140.

[0076] Among them, by setting the sheet metal part 1242, the contact area between the support member 120 and the bottom wall of the cavity 1102 can be increased, thereby improving the stability of the support member 120 and preventing the support member 120 from shaking in the cavity 1102. By setting the support column 1244, effective support can be provided for the mounting plate 122, preventing the mounting plate 122 from skewing or even collapsing. Furthermore, the technical effects of improving the structural stability of the support member 120 and improving the positioning accuracy of the first electrical component 130 are achieved.

The first electrical component 130 further includes a fuse, and the fuse includes a main positive fuse 1322 and a heating fuse 1324. The first electrical component 130 further includes a relay, and the relay includes a main positive relay 1332, a main negative relay 1334, a heating relay 1336, and a pre-charge relay 1338. The first electrical component 130 further includes a shunt 134 and a current sensor 135. Specifically, the current sensor 135 is a Hall sensor. The first electrical component 130 further includes a parallel port conversion box 136 and an energy storage inverter 137.

[0083] The second electrical component 140 includes a lightning protection module 141, a light-emitting component 142, a circuit breaker 143, a network interface 144, and a chip 145. Among them, the light-emitting component 142 is an LED lamp. The circuit breaker 143 is fixed on a circuit breaker bracket 1434, and a circuit breaker protective cover 1432 is arranged outside the circuit breaker 143. The chip 145 is fixed on a chip bracket 1452.

[0084] Specifically, a first side plate 162 and a second side plate 164 are connected to the outside of the housing 110. A nameplate 160 is arranged on the second side plate 164, and parameter information of the energy storage control component 100 is used to be recorded on the nameplate 160. The first side plate 162 can provide protection for the interfaces on the housing 110.

[0085] As Figure 1 and Figure 2 shown, in some embodiments of the present utility model, optionally, the housing 110 includes: a box body 112, the box body 112 includes an opening 1122, a cover body 114, the cover body 114 is flange-connected to the box body 112, and the cover body 114 covers the opening 1122; a sealing ring 116, the sealing ring 116 is arranged between the cover body 114 and the box body 112, and the sealing ring 116 is used to seal the gap between the cover body 114 and the box body 112.

[0086] In this embodiment, the housing 110 includes a box body 112 and a cover body 114. An opening 1122 is arranged at the top of the box body 112, and electrical components can be loaded into the interior of the box body 112 through the opening 1122. During subsequent use, the user can also maintain and repair the electrical components inside the box body 112 at the opening 1122.

[0087] On this basis, the cover body 114 covers above the opening 1122, and the cover body 114 is flange-connected to the box body 112. On the one hand, the flange connection has the advantage of being detachable, which can provide convenient conditions for disassembling and assembling electrical components and reduce the difficulty of replacing and maintaining electrical components. On the other hand, the flange connection has strong sealing performance, which can reduce the probability of sealing dead corners between the box body 112 and the cover body 114.

[0088] Among them, a sealing ring 116 is clamped between the cover body 114 and the box body 112. The sealing ring 116 surrounds the periphery of the opening 1122. The sealing ring 116 can fill the gap between the cover body 114 and the box body 112, thereby sealing the gap between the cover body 114 and the box body 112 to prevent pollutants such as dust and liquid from entering the interior of the box body 112, reduce the probability of electrical component failures and damages caused by pollutants, and further achieve the technical effects of improving the sealing performance of the energy storage control component 100, reducing the failure rate of electrical components, and extending the service life of electrical components.

[0089] As Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments of the present utility model, optionally, the box body 112 includes a top surface 1124, an opening 1122 is provided on the top surface 1124, and a sealing ring 116 is press-fitted between the cover body 114 and the top surface 1124; the sealing ring 116 is foam-molded on the cover body 114.

[0090] In this embodiment, one side of the box body 112 facing the cover body 114 includes a top surface 1124, an opening 1122 is opened in the central area of the top surface 1124, and the top surface 1124 is flange-connected to the cover body 114.

[0091] On this basis, the sealing ring 116 is foam-molded on the lower surface of the cover body 114. The foam-molded sealing ring 116 is disposed opposite to the top surface 1124. After the foaming is completed, the cover body 114 can be covered above the top surface 1124, and the sealing ring 116 is clamped by the end surface under the flange connection and the cover body 114, so that the foam-molded sealing ring 116 deforms under extrusion, and the gap between the cover body 114 and the top surface 1124 is filled through the deformation, preventing pollutants from entering the inner side of the box body 112 between the cover body 114 and the top surface 1124, thereby achieving the technical effects of improving the sealing reliability of the energy storage control assembly 100 and reducing the failure rate of electrical components. At the same time, forming the sealing ring 116 by the foaming process can reduce the process complexity of the energy storage control assembly 100, which is beneficial to reducing the production cost of the energy storage control assembly 100.

[0092] As Figure 1 and Figure 3 shown, in some embodiments of the present utility model, optionally, the cover body 114 includes a through hole 1142, and the energy storage control assembly 100 further includes: nuts 150, which are disposed on the top surface 1124, the number of nuts 150 is multiple, and the multiple nuts 150 are distributed around the opening 1122, and the through hole 1142 is opposite to the nuts 150; a connecting member, the connecting member passes through the through hole 1142, and the connecting member is connected to the nuts 150, and the connecting member is used to press-fit the cover body 114 onto the nuts 150.

[0093] In this embodiment, a plurality of through holes 1142 are provided on the cover body 114, and the plurality of through holes 1142 are arranged in a loop on the cover body 114 to form an array. Correspondingly, nuts 150 are provided on the top surface 1124 of the box body 112, and the number of nuts 150 is the same as the number of through holes 1142. During the assembly process, the plurality of through holes 1142 and the plurality of nuts 150 correspond to each other one by one.

[0094] The energy storage control assembly 100 further includes a connecting member. The connecting member passes through the cover body 114 through the through hole 1142 and is screwed to the nuts 150 below the through hole 1142. Connecting multiple groups of through holes 1142 and nuts 150 through multiple connecting members respectively can complete the flange connection between the cover body 114 and the box body 112.

[0095] Specifically, during the assembly process, the cover 114 is initially positioned on the box body first, so that the sealing ring 116 abuts against the top surface 1124, and the through hole 1142 is aligned with the nut 150. Then, the cover 114 is pressed and installed downward by inserting a connecting component. During this process, the sealing ring 116 is compressed and deformed until the lower surface of the cover 114 is assembled with the upper surface of the nut 150. At this time, the sealing ring 116 deformed under pressure fills the gap between the cover 114 and the top surface 1124 to achieve effective sealing.

[0096] Specifically, in the present application, based on the flange connection and in cooperation with the sealing ring 116 for sealing, the waterproof level of the energy storage control component 100 can be improved to IP67.

[0097] Specifically, the connecting component includes screws and bolts.

[0098] In some embodiments of the present utility model, optionally, in the height direction of the box body 112, the dimension range of the nut 150 is: greater than or equal to 1 mm and less than or equal to 3 mm.

[0099] In this embodiment, in the height direction of the box body 112, the dimension of the nut 150 is the height of the nut 150. The height of the nut 150 corresponds to the distance that the nut 150 protrudes from the top surface 1124. After the assembly is completed, the top surface 1124 of the nut 150 contacts the bottom surface of the cover 114, and this distance corresponds to the height available for accommodating the sealing ring 116.

[0100] On this basis, the height of the nut 150 needs to be greater than or equal to 1 mm and less than or equal to 3 mm.

[0101] By defining that the height of the nut 150 is greater than or equal to 1 mm, sufficient layout space can be reserved for the sealing ring 116, ensuring that the cover 114 can be smoothly pressed and installed above the nut 150, and reducing the sealing and assembly difficulty of the energy storage control component 100.

[0102] By defining that the height of the nut 150 is less than or equal to 3 mm, on the basis of meeting the space layout requirements of the sealing ring 116, the gap between the cover 114 and the top surface 1124 can be reduced, thereby reducing the sealing difficulty of the sealing ring 116 for this gap and improving the sealing effect between the cover 114 and the box body 112.

[0103] Specifically, the height of the nut 150 is 2 mm, and the thickness of the sealing ring 116 is greater than the height of the nut 150 to ensure that the sealing ring 116 can be compressed.

[0104] Such as Figure 1 and Figure 3As shown, in some embodiments of the present utility model, optionally, the energy storage control component 100 further includes: a positioning pin 1144, which is provided on the side of the cover 114 facing the opening 1122, and the cover 114 includes a first posture and at least one second posture; when the cover 114 is in the first posture, the positioning pin 1144 avoids the electrical component, and the cover 114 can be fastened to the box body 112; when the cover 114 is in the second posture, the positioning pin 1144 interferes with the electrical component, and the cover 114 cannot be fastened to the box body 112.

[0105] In this embodiment, a positioning pin 1144 is provided on the side of the cover 114 facing the box body 112, and the positioning pin 1144 avoids the top surface 1124 of the box body 112 and faces the opening 1122 of the box body 112. During the assembly process, the internal structure of the box body 112 needs to be assembled first, and then the cover 114 is fastened. During the process of fastening the cover 114, the positioning pin 1144 extends into the box body 112.

[0106] The positioning pin 1144 is eccentrically arranged on the cover 114. When the cover 114 is initially positioned above the box body 112 of the box body 112, the cover 114 includes a first posture and at least one second posture.

[0107] For example, when the horizontal cross-section of the box body 112 is rectangular, the cover 114 placed on the box body 112 includes two possibilities of being correct and reversed. The correct placement posture is the first posture, and the reversed placement posture corresponds to the second posture. Or when the horizontal cross-section of the box body 112 is square, the cover 114 placed on the box body 112 includes a first posture and three second postures.

[0108] On this basis, when the cover 114 initially positioned above the box body 112 is in the correct first posture, the positioning pin 1144 can smoothly extend into the internal space of the box body 112, and the positioning pin 1144 will not interfere with the internal structure of the box body 112. The cover 114 can be smoothly pressed onto the top surface 1124 through the connecting component.

[0109] When the cover 114 initially positioned on the box body 112 is in the wrong second posture, the positioning pin 1144 will be blocked by the electrical component in the box body 112, resulting in the positioning pin 1144 being unable to continue extending downward. At this time, the cover 114 is lifted, and the connecting component connecting nut 150 cannot be operated, thereby timely reminding the worker or user that the pre-assembly posture of the cover 114 is incorrect.

[0110] It can be seen that by setting the positioning pin 1144, the anti-fool design of the cover 114 can be realized, avoiding the misalignment installation of the cover 114, and further achieving the technical effects of improving the assembly accuracy of the energy storage control component 100 and increasing the yield rate of the energy storage control component 100.
