Description

Technical Field

[0001] This application relates to the field of energy storage power technology, and in particular to a conductive connection component and an energy storage power supply. Background Technology

[0002] Energy storage devices consist of battery packs and circuit boards, which are electrically connected via busbars. During production and installation, before the circuit board and busbars are connected, the end of the busbar may accidentally come into contact with the metal parts of the circuit board, potentially causing arcing or short circuits. In related technologies, production and installation personnel typically add discharge tubes to the power circuit board or use auxiliary materials such as PC sheets (also known as polycarbonate sheets) or adhesive tape to isolate the busbars and the circuit board. However, these methods increase production costs, increase the size of the power circuit board, and reduce production efficiency. Utility Model Content

[0003] In view of this, this application provides a conductive connection component and an energy storage power supply to improve the technical problems of poor assembly efficiency and high production cost of existing energy storage power supplies.

[0004] One embodiment of this application provides a conductive connection assembly for use in an energy storage power supply. The energy storage power supply includes a battery pack and a circuit board. The conductive connection assembly includes a magnetic element, a conductive busbar, and fasteners. The magnetic element is configured to be fixed relative to the circuit board and spaced apart from it. One end of the conductive busbar is configured to be electrically connected to the battery pack, and the other end has a fixing portion. The fixing portion is configured to be located between the circuit board and the magnetic element, and is able to move away from the circuit board under the action of the magnetic element. The fasteners are configured to pass through the circuit board and the fixing portion when electrical connection between the conductive busbar and the circuit board is required, and to move the fixing portion closer to the circuit board until the fixing portion is in contact with the circuit board.

[0005] Before connecting the circuit board and the busbar, the end of the busbar with the fixing part is spaced apart from the circuit board and moved away from the circuit board by the magnetic component, which can reduce the risk of arcing and short circuit due to contact between the busbar and the circuit board. When it is necessary to electrically connect the busbar and the circuit board, the fastener passes through the circuit board and the fixing part, and moves the fixing part closer to the circuit board until the fixing part is in contact with the circuit board. By using the conductive connection component provided in this application, firstly, there is no need to add expensive discharge devices, which helps to reduce the production cost of energy storage power supply; secondly, production and installation personnel do not need complicated material placement operations, which helps to reduce the difficulty of operation and improve the assembly efficiency of energy storage power supply.

[0006] In some embodiments of this application, the conductive busbar is configured to be connected to the negative terminal of the battery pack.

[0007] Before the circuit board and the busbar are connected, the busbar connected to the negative terminal of the battery pack can be kept away from the circuit board with the cooperation of the magnetic component and the fixing part. This helps to reduce the risk that the negative terminal of the battery pack may accidentally touch the circuit board when it is close to the circuit board, forming a short circuit loop, generating a large current instantaneously, and causing arcing and short circuit.

[0008] In some embodiments of this application, the number of conductive busbars is two, one of which is configured to be connected to the negative terminal of the battery pack, and the other is configured to be connected to the positive terminal of the battery pack.

[0009] Before the circuit board and the busbars are connected, the busbars connected to the negative terminal of the battery pack and the busbars connected to the positive terminal of the battery pack can be kept away from the circuit board with the cooperation of the magnetic components and the fixing parts. This helps to reduce the risk of the negative and positive terminals of the battery pack accidentally touching the circuit board when they are close to the circuit board, forming a short circuit, generating a large current instantaneously, and causing arcing and short circuit.

[0010] In some embodiments of this application, the conductive busbar has a first end and a second end, the first end being configured to be electrically connected to the battery pack, and the second end being configured to be riveted with a carbon steel nut to form the fixing portion.

[0011] By riveting a carbon steel nut to the second end of the busbar to form a fixing part, the structural strength and connection reliability of the fixing part can be improved, which is beneficial to extending the service life of the busbar. In addition, the carbon steel nut can interact with magnetic components, so the selection of materials for the busbar is not limited to materials that can interact with magnetic components.

[0012] In some embodiments of this application, the conductive connection assembly further includes a fixing bracket configured to be fixed within the energy storage power supply. The fixing bracket has a mounting groove configured to accommodate one end of the conductive busbar having a fixing portion. A magnetic element is mounted on the fixing bracket and disposed close to the mounting groove. Along the spacing direction between the magnetic element and the circuit board, the projection of the magnetic element at least partially overlaps with the mounting groove.

[0013] The mounting slot allows for precise positioning of the busbar during installation. The magnetic component's proximity to the mounting slot ensures accurate interaction between the busbar and the magnetic component during installation, further reducing the risk of arcing and short circuits caused by contact between the busbar and the circuit board.

[0014] In some embodiments of this application, the fixing bracket is further provided with a receiving groove, which is arranged adjacent to the assembly groove along the interval direction and is connected to the assembly groove, so that the magnetic component is exposed in the assembly groove. When one end of the conductive bar with the fixing part is received in the assembly groove, at least part of the fixing part is received in the receiving groove and interacts with the magnetic component.

[0015] The magnetic component can be limited by the setting of the receiving groove, and the receiving groove is set adjacent to the assembly groove, which can increase the force of the magnetic component on the conductive bus located in the receiving groove.

[0016] In some embodiments of this application, the fixing bracket is further provided with a limiting part at the opening of the receiving groove. The limiting part abuts against the magnetic component and is configured to prevent the magnetic component from falling out of the receiving groove.

[0017] When the magnetic component is mounted on the fixed bracket, the limiting part abuts against the top surface of the magnetic component to stop it, thus constraining the phase position between the magnetic component and the fixed bracket. This reduces the risk of the magnetic component detaching from the fixed bracket due to impact, and helps to further reduce the risk of short circuits and arcing in the energy storage power supply.

[0018] In some embodiments of this application, when there are two conductive bars, and one of the two conductive bars is configured to be connected to the negative terminal of the battery pack and the other is configured to be connected to the positive terminal of the battery pack, the fixing bracket is provided with a partition baffle in the assembly slot, and the partition baffle is configured to separate the two conductive bars.

[0019] By setting up a separator, the two conductive bars connected to the positive and negative terminals of the battery pack can be separated, thus achieving isolation between the positive and negative terminals in the battery pack, which helps reduce the risk of short circuit between the positive and negative terminals in the battery pack.

[0020] In some embodiments of this application, the magnetic component has a clearance hole, the projection of the fixing part along the interval direction overlaps with the clearance hole, and the clearance hole is configured to allow fasteners to pass through.

[0021] During the process of the fastener driving the fixing part closer to the circuit board, the clearance hole can avoid the end of the fastener, reducing the risk of damage to components (such as circuit boards, conductors, etc.) due to interference between the fastener and magnetic components, or the risk that the fixing end of the conductor and the circuit board cannot be tightly connected, which is beneficial to improving the safety and reliability of energy storage power supply assembly.

[0022] One embodiment of this application provides an energy storage power supply. The energy storage power supply includes a battery pack, a circuit board, and a conductive connection component as described in any of the above embodiments. The battery pack is connected to the circuit board via the conductive connection component.

[0023] The aforementioned energy storage power supply utilizes the aforementioned conductive connection components. The end of the conductive busbar with a fixing part is spaced apart from the circuit board and, under the influence of a magnetic component, is kept away from the circuit board, reducing the risk of arcing and short circuits caused by contact between the conductive busbar and the circuit board. When electrical connection between the conductive busbar and the circuit board is required, fasteners are inserted through the circuit board and the fixing part, and the fixing part is moved closer to the circuit board until it is in contact with the circuit board. Therefore, firstly, there is no need to add expensive discharge devices, which helps reduce the production cost of the energy storage power supply; secondly, production and installation personnel do not need complex material application operations, which helps reduce operational difficulty and improve the assembly efficiency of the energy storage power supply.

[0027] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0029] Energy storage devices consist of battery packs and circuit boards, which are electrically connected via busbars. During production and installation, before the circuit board and busbars are connected, the end of the busbar may accidentally come into contact with the metal parts of the circuit board, potentially causing arcing or short circuits. In related technologies, production and installation personnel typically add discharge tubes to the power circuit board or use auxiliary materials such as PC sheets (also known as polycarbonate sheets) or adhesive tape to isolate the busbars and the circuit board. However, these methods increase production costs, increase the size of the power circuit board, and reduce production efficiency.

[0030] One embodiment of this application provides a conductive connection assembly for use in an energy storage power supply. The energy storage power supply includes a battery pack and a circuit board. The conductive connection assembly includes a magnetic element, a conductive busbar, and fasteners. The magnetic element is configured to be fixed relative to the circuit board and spaced apart from it. One end of the conductive busbar is configured to be electrically connected to the battery pack, and the other end has a fixing portion. The fixing portion is configured to be located between the circuit board and the magnetic element, and is able to move away from the circuit board under the action of the magnetic element. The fasteners are configured to pass through the circuit board and the fixing portion when electrical connection between the conductive busbar and the circuit board is required, and to move the fixing portion closer to the circuit board until the fixing portion is in contact with the circuit board.

[0031] Before connecting the circuit board and the busbar, the end of the busbar with the fixing part is spaced apart from the circuit board and moved away from the circuit board by the magnetic component, which can reduce the risk of arcing and short circuit due to contact between the busbar and the circuit board. When it is necessary to electrically connect the busbar and the circuit board, the fastener passes through the circuit board and the fixing part, and moves the fixing part closer to the circuit board until the fixing part is in contact with the circuit board. By using the conductive connection component provided in this application, firstly, there is no need to add expensive discharge devices, which helps to reduce the production cost of energy storage power supply; secondly, production and installation personnel do not need complicated material placement operations, which helps to reduce the difficulty of operation and improve the assembly efficiency of energy storage power supply.

[0032] In the aforementioned conductive connection assembly, the end of the conductive busbar with a fixing part is spaced apart from the circuit board and, under the action of the magnetic component, is moved away from the circuit board, which reduces the risk of arcing and short circuits when the conductive busbar contacts the circuit board. When electrical connection between the conductive busbar and the circuit board is required, fasteners are inserted through the circuit board and the fixing part, and the fixing part is moved closer to the circuit board until it is in contact with the circuit board. Firstly, there is no need to add expensive discharge devices, which helps to reduce the production cost of the energy storage power supply; secondly, production and installation personnel do not need complicated material placement operations, which helps to reduce the difficulty of operation and improve the assembly efficiency of the energy storage power supply.

[0033] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0034] Please see Figure 1 One embodiment of this application provides an energy storage power supply 100. The energy storage power supply 100 has the functions of storing and discharging electricity, and can be used for household backup power, production unit backup power, outdoor work, outdoor recreation, etc.

[0035] Please refer to the following: Figures 2 to 4 In some embodiments, the energy storage power supply 100 includes a battery pack 10, a circuit board 20, and a conductive connection assembly 30. The battery pack 10 is connected to the circuit board 20 via the conductive connection assembly 30.

[0036] In some embodiments, the battery pack 10 comprises multiple battery cells (not shown). The battery pack 10 is used for energy storage and power supply of the energy storage power supply 100. The battery pack 10 can also be used as a standalone device to output DC power, or it can be stacked together with an inverter module.

[0037] In some embodiments, the energy storage power supply 100 includes a power conversion module (not shown), which is electrically connected to the battery pack 10. The power conversion module is used to control the AC / DC conversion of the output current of the battery pack 10. The energy storage power supply 100 equipped with the power conversion module can be a small portable power supply, a residential energy storage power supply 100, an industrial or commercial energy storage power supply 100, or a containerized energy storage power supply 100, etc.

[0038] In some embodiments, the power conversion module may be omitted. An energy storage power supply 100 without a power conversion module can be used independently. An energy storage power supply 100 without a power conversion module typically only outputs DC power. When used independently, an energy storage power supply 100 without a power conversion module can be used in conjunction with an energy storage power supply 100 with a power conversion module to provide additional battery capacity as a power system.

[0039] In some embodiments, circuit board 20 may be a BMS (Battery Management System) board or a PSDR (Power Supply Driver) board.

[0040] Please refer to the following: Figure 3 and Figure 4 In some embodiments, the conductive connection assembly 30 includes a magnetic element 31, a conductive bar 32, and a fastener 33. The magnetic element 31 is configured to be fixed relative to the circuit board 20 and spaced apart from the circuit board 20. Preferably, the magnetic element 31 is a magnet.

[0041] One end of the conductive busbar 32 is configured to be electrically connected to the battery pack 10, and the other end is provided with a fixing part 321. The fixing part 321 is constructed to be located between the circuit board 20 and the magnetic element 31, and can be moved away from the circuit board 20 under the action of the magnetic element 31.

[0042] The fastener 33 is configured to pass through the circuit board 20 and the fixing part 321 when it is necessary to electrically connect the conductive busbar 32 and the circuit board 20, and to move the fixing part 321 closer to the circuit board 20 until the fixing part 321 is in contact with the circuit board 20.

[0043] Understandably, before the circuit board 20 and the conductive busbar 32 are connected, one end of the conductive busbar 32 with the fixing part 321 is spaced apart from the circuit board 20 and moves away from the circuit board 20 under the action of the magnetic element 31, thereby reducing the risk of arcing and short circuit when the conductive busbar 32 comes into contact with the circuit board 20 before the circuit board 20 and the conductive busbar 32 are connected.

[0044] When it is necessary to electrically connect the conductive busbar 32 and the circuit board 20, the fastener 33 passes through the circuit board 20 and the fixing part 321, and moves the fixing part 321 closer to the circuit board 20 until the fixing part 321 is in contact with the circuit board 20.

[0045] By adopting the conductive connection component 30 provided in this application, firstly, there is no need to add expensive discharge devices, which helps to reduce the production cost of the energy storage power supply 100; secondly, production and installation personnel do not need complicated material placement operations, which helps to reduce the difficulty of operation and improve the assembly efficiency of the energy storage power supply 100.

[0046] In some embodiments, the conductive busbar 32 is configured to be connected to the negative terminal 11 of the battery pack 10. Understandably, before the circuit board 20 and the conductive busbar 32 are connected, the conductive busbar 32 connected to the negative terminal 11 in the battery pack 10 is moved away from the circuit board 20 by the cooperation of the magnetic element 31 and the fixing part 321, that is, the negative terminal 11 of the battery pack 10 is moved away from the circuit board 20.

[0047] By keeping the negative terminal 11 of the battery pack 10 away from the circuit board 20, it is beneficial to reduce the risk of arcing or short circuit caused by accidental contact between the conductive bar 32 connected to the negative terminal 11 of the battery pack 10 and the metal part on the circuit board 20 before the circuit board 20 and the conductive bar 32 are connected.

[0048] Please see Figure 2 In some embodiments, there are two conductive bars 32, one of which is configured to be connected to the negative terminal 11 of the battery pack 10, and the other is configured to be connected to the positive terminal 12 of the battery pack 10.

[0049] Understandably, before the circuit board 20 and the conductive busbar 32 are connected, the conductive busbar 32 connected to the negative terminal 11 of the battery pack 10 and the conductive busbar 32 connected to the positive terminal 12 of the battery pack 10 can both move away from the circuit board 20 with the cooperation of the magnetic component 31 and the fixing part 321, that is, the negative terminal 11 and the positive terminal 12 of the battery pack 10 are both away from the circuit board 20.

[0050] By keeping both the positive terminal 12 and the negative terminal 11 of the battery pack 10 away from the circuit board 20, it is beneficial to better reduce the risk of arcing or short circuit caused by accidental contact between the conductive bus 32 connected to the negative terminal 11 of the battery pack 10 or the conductive bus 32 connected to the positive terminal 12 of the battery pack 10 and the metal parts on the circuit board 20 before the circuit board 20 and the conductive bus 32 are connected.

[0051] In other embodiments, the busbar 32 may also be connected to the input terminal and / or the output terminal of the battery pack 10. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0052] Please refer to the following: Figures 2 to 4 In some embodiments, the conductive bus 32 has a first end 322 and a second end 323. The first end 322 is configured to be electrically connected to the battery pack 10. The second end 323 is configured to be riveted with a carbon steel nut to form the fixing portion 321.

[0053] By riveting a carbon steel nut to the second end 323 of the conductive busbar 32 to form a fixing part 321, the structural strength and connection reliability of the fixing part 321 can be improved, which is beneficial to extending the service life of the conductive busbar 32. In addition, the carbon steel nut can interact with the magnetic component 31, so that the material selection of the conductive busbar 32 is not limited to materials that can interact with the magnetic component 31.

[0054] For example, before the circuit board 20 and the conductive busbar 32 are connected, one end of the conductive busbar 32 with a carbon steel nut is spaced apart from the circuit board 20 and moved away from the circuit board 20 by the magnetic element 31. When electrical connection between the conductive busbar 32 and the circuit board 20 is required, a fastener 33 (specifically, a screw, threaded component, etc.) passes through the circuit board 20 and the carbon steel nut. By tightening the fastener 33, the carbon steel nut is brought closer to the circuit board 20 until it is in contact with the circuit board 20, thus achieving electrical connection between the conductive busbar 32 and the circuit board 20.

[0055] In other embodiments, the conductive bus 32 may not require riveting with a carbon steel nut. For example, the conductive bus 32 may be entirely made of metal, and its second end 323 may have a threaded hole that mates with a fastener 33 to form the fixing portion 321. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0056] Please refer to the following: Figures 4 to 6 In some embodiments, the conductive connection assembly 30 further includes a fixing bracket 34 configured to be fixed within the energy storage power supply 100. The fixing bracket 34 has a mounting groove 341 configured to accommodate one end of the conductive busbar 32 having a fixing portion 321. A magnetic element 31 is mounted on the fixing bracket 34 and disposed close to the mounting groove 341. Along the spacing direction between the magnetic element 31 and the circuit board 20, the projection of the magnetic element 31 at least partially overlaps with the mounting groove 341.

[0057] The assembly slot 341 allows for the limiting of the conductive busbar 32 during installation. The magnetic component 31 is positioned close to the assembly slot 341, ensuring precise interaction between the conductive busbar 32 and the magnetic component 31 during installation, thus further reducing the risk of arcing and short circuits caused by contact between the conductive busbar 32 and the circuit board 20.

[0058] In some embodiments, along the spacing direction, when one end of the conductive busbar 32 with the fixing part 321 is accommodated in the assembly groove 341, the gap between the conductive busbar 32 and the circuit board 20 is 1mm, so as to ensure that before the circuit board 20 and the conductive busbar 32 are connected, the end of the conductive busbar 32 will not accidentally contact the circuit board 20, resulting in arcing or short circuit.

[0059] In some embodiments, the fixed bracket 34 is further provided with a receiving groove 342, which is arranged adjacent to the assembly groove 341 along the interval direction, and the receiving groove 342 is connected to the assembly groove 341 so that the magnetic component 31 is exposed in the assembly groove 341.

[0060] When one end of the conductive busbar 32 with the fixing part 321 is received in the assembly groove 341, at least a portion of the fixing part 321 is received in the receiving groove 342 and interacts with the magnetic element 31. The receiving groove 342 can limit the magnetic element 31, and the adjacent arrangement of the receiving groove 342 and the assembly groove 341 can increase the force exerted by the magnetic element 31 on the conductive busbar 32 located in the receiving groove 342.

[0061] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the fixing bracket 34 is further provided with a limiting part 343 at the opening of the receiving groove 342. The limiting part 343 abuts against the magnetic member 31 and is configured to prevent the magnetic member 31 from falling out of the receiving groove 342.

[0062] When the magnetic component 31 is mounted on the fixed bracket 34, the limiting part 343 abuts against the top surface of the magnetic component 31 to stop the magnetic component 31, that is, to constrain the phase position of the magnetic component 31 and the fixed bracket 34. As a result, the risk of the magnetic component 31 detaching from the fixed bracket 34 due to impact can be reduced, which is beneficial to further reduce the risk of short circuit and arcing in the energy storage power supply 100.

[0063] In some embodiments, the fixed bracket 34 is provided with a snap-fit ​​portion 344, through which the magnetic component 31 is detachably mounted to the fixed bracket 34. By adopting a snap-fit ​​mounting method, it is beneficial for subsequent maintenance and replacement of the magnetic component 31. It is only necessary to release the snap-fit ​​between the snap-fit ​​portion 344 and the magnetic component 31, without causing irreversible damage to the component, thus reducing maintenance costs.

[0064] In other embodiments, the magnetic component 31 may also be installed by other methods such as bonding. This application does not limit this method, and those skilled in the art can choose according to the actual situation.

[0065] Please see Figure 4 In some embodiments, the fixing bracket 34 is configured to create an assembly gap 35 between the fixing part 321 and the magnetic element 31. By providing an assembly gap 35, the risk of the fixing part 321 and the magnetic element 31 becoming "hard-engaged" and unable to separate due to an insufficient distance between them can be reduced.

[0066] This improves the ease of operation of the conductive connection component 30, avoiding the need for production and installation personnel to use a large force to tighten the fastener 33 (specifically, to overcome the magnetic force) in order to move the fixing part 321 close to the circuit board 20.

[0067] Please refer to the following: Figure 3 , Figure 4 and Figure 6In some embodiments, when there are two conductive bars 32, and one of the two conductive bars 32 is configured to be connected to the negative terminal 11 of the battery pack 10 and the other is configured to be connected to the positive terminal 12 of the battery pack 10, the fixing bracket 34 is provided with a partition baffle 345 in the assembly groove 341, and the partition baffle 345 is configured to space the two conductive bars 32.

[0068] By setting the separator 345, the two conductive bars 32 connected to the positive electrode 12 and the negative electrode 11 of the battery pack 10 can be separated, that is, the positive electrode 12 and the negative electrode 11 in the battery pack 10 are isolated, which helps to reduce the risk of short circuit between the positive electrode 12 and the negative electrode 11 in the battery pack 10.

[0069] Please refer to the following: Figure 4 , Figure 6 and Figure 7 In some embodiments, the magnetic component 31 has a clearance hole 311, and the projection of the fixing part 321 along the interval direction overlaps with the clearance hole 311. The clearance hole 311 is configured to allow the fastener 33 to pass through.

[0070] As the fastener 33 moves the fixing part 321 closer to the circuit board 20, the clearance hole 311 can avoid the end of the fastener 33. This reduces the risk of damage to components (such as the circuit board 20, the conductive busbar 32, etc.) due to interference between the fastener 33 and the magnetic component 31, or the risk that the fixing end of the conductive busbar 32 cannot be tightly connected to the circuit board 20, which helps to improve the safety and reliability of the energy storage power supply 100 assembly.

[0071] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
