Description

Technical Field

[0001] The present disclosure relates to the technical field of energy storage power supplies, and particularly to a conductive connection structure, an energy storage power supply, and an assembly method for an energy storage power supply. Background Art

[0002] During the assembly process of current related energy storage power supplies, such as in Patent 201910850826.X, it is necessary to connect the total positive or total negative pole of the power supply module to the total positive or total negative pole of the power management module. At the same time, an aluminum sheet is installed on the total positive or total negative pole of the power supply module, and then the hardware terminal is connected to the aluminum sheet by welding or screwing to enable the conductive end of the power supply module to be in contact with and electrically connected to the conductive end of the power management module.

[0003] However, there is a risk problem in the assembly process of most current energy storage power supplies: when the power management module is assembled onto the power supply module, if the positive pole or the solder feet of other components on the power management module touch the aluminum sheet at the positive pole of the power supply module first, the energy storage power supply will generate an impact current due to a voltage mutation, thereby damaging or even destroying the electronic circuits, components, and battery cells inside the energy storage power supply. This makes it necessary to connect the total negative pole first during the power-on process of the energy storage power supply assembly, and the total positive pole cannot be directly connected. Otherwise, there is likely to be a problem of burning the electronic board or damaging the battery cells during the subsequent production and assembly process of the energy storage power supply, which not only greatly increases the assembly difficulty of the energy storage power supply, but also easily causes damage or even destruction during the assembly process of the energy storage power supply, resulting in a significant increase in the scrap rate of the energy storage power supply, and further greatly increasing the production cost of the energy storage power supply.

The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail with specific embodiments as follows: Such as Figures 1 to 10As shown, a conductive connection structure 10 of an embodiment is used to be installed in an energy storage power supply. The conductive connection structure 10 includes a power supply component 100 and a power management component 200. The power supply component 100 includes a first conductive member 110 and a power supply member 120. The first conductive member 110 is fixed and electrically connected to the conductive end of the power supply member 120. The power management component 200 includes a second conductive member 210 and a control board 220. The second conductive member 210 is fixed and electrically connected to the conductive end of the control board 220. The control board 220 is installed at a preset position of the power supply member 120 so that the first conductive member 110 and the second conductive member 210 are arranged opposite to each other. A support portion 121 is formed on a side surface of the power supply member 120 adjacent to the control board 220. The support portion 121 is used to support the control board 220 away from the power supply member 120 so that a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210. When the power management component 200 is installed on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from touching the positive electrode of the power supply component 100 first, which may cause the energy storage power supply to generate an impact current and damage the internal electronic circuits, components and battery cells 122 of itself. This not only greatly reduces the assembly difficulty of the energy storage power supply, but also greatly reduces the possibility of generating an impact current during the assembly process of the energy storage power supply, greatly reducing the scrap rate of the energy storage power supply, and further greatly reducing the production cost of the energy storage power supply.

[0025] In this embodiment, when the conductive connection structure 10 needs to be installed in the energy storage power supply, first install the power supply component 100 in the energy storage power supply; then install the power management component 200 at the preset position of the power supply component 100 so that the first conductive member 110 and the second conductive member 210 can be arranged opposite to each other. At the same time, the support portion 121 can support and limit the control board 220 so that a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210, avoiding that during the assembly process of the energy storage power supply, the positive electrode of the power management component 200 touches the positive electrode of the power supply component 100 first, which may cause the energy storage power supply to generate an impact current and damage the internal electronic circuits, components and battery cells 122 of itself; finally, in the connection sequence of connecting the negative electrode first and then the positive electrode, fix and electrically connect the second conductive member 210 of the power management component 200 and the first conductive member 110 of the power supply component 100.

[0026] For the above-described conductive connection structure 10, since the control board 220 is installed at a preset position of the power supply component 120, the first conductive member 110 and the second conductive member 210 are arranged opposite to each other; a support portion 121 is formed on a side surface of the power supply component 120 adjacent to the control board 220, and the support portion 121 is used to support the control board 220 away from the power supply component 120, so that a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210. During the installation of the power management component 200 on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from touching the positive electrode of the power supply component 100 first, which may cause an impact current in the energy storage power supply and damage the internal electronic circuits, components, and battery cells 122. This not only greatly reduces the assembly difficulty of the energy storage power supply but also significantly reduces the possibility of generating an impact current during the assembly process of the energy storage power supply, greatly reducing the scrap rate of the energy storage power supply and thus significantly reducing the production cost of the energy storage power supply.

[0027] It can be understood that when the safety gap 300 between the first conductive member 110 and the second conductive member 210 is too small, the first conductive member 110 and the second conductive member 210 will conduct, making it easy for the positive electrode of the power management component 200 to conduct with the positive electrode of the power supply component 100 first, resulting in an impact current in the energy storage power supply and damaging the internal electronic circuits, components, and battery cells 122; while when the safety gap 300 between the first conductive member 110 and the second conductive member 210 is too large, the second conductive member 210 cannot be abutted and fixed to the first conductive member 110, preventing conduction between the first conductive member 110 and the second conductive member 210.

[0028] As Figure 4 shown, in one embodiment, the spacing of the safety gap 300 is 0.8 mm - 1 mm, to avoid conduction between the first conductive member 110 and the second conductive member 210 due to too small a spacing between them, preventing the positive electrode of the power management component 200 from conducting with the positive electrode of the power supply component 100 first, which may cause an impact current in the energy storage power supply and damage the internal electronic circuits, components, and battery cells 122. At the same time, it also avoids the inability to abut and fix the first conductive member 110 and the second conductive member 210 due to too large a spacing between them, thus greatly reducing the assembly difficulty of the energy storage power supply.

[0029] As Figure 1 and Figure 2As shown, in one embodiment, the first conductive member 110 is welded to the conductive end of the power supply member 120, so that the first conductive member 110 can be firmly fixed to the conductive end of the power supply member 120, greatly improving the electrical connection stability between the power supply member 120 and the first conductive member 110, and thus greatly improving the usage stability of the energy storage power supply.

[0030] As Figure 1 and Figure 2 shown, in one embodiment, the second conductive member 210 is welded to the conductive end of the control board 220, so that the second conductive member 210 can be firmly fixed to the conductive end of the control board 220, greatly improving the electrical connection stability between the control board 220 and the second conductive member 210, and thus greatly improving the usage stability of the energy storage power supply.

[0031] As Figure 4 and Figure 7 shown, in one embodiment, a welding hole 221 is formed at the conductive end of the control board 220, and welding feet 211 protrude from the outer periphery of the second conductive member 210. The welding feet 211 pass through the welding hole 221, and the outer peripheral wall of the welding feet 211 is welded to the inner peripheral wall of the welding hole 221 to increase the welding area between the second conductive member 210 and the conductive end of the control board 220. This not only enables the second conductive member 210 to be more firmly fixed to the control board 220, but also increases the power connection area between the second conductive member 210 and the conductive end of the control board 220 to reduce the power connection resistance between the second conductive member 210 and the control board 220, thereby improving the power supply efficiency and electrical connection stability between the control board 220 and the second conductive member 210.

[0032] As Figure 4 and Figure 7 shown, in one embodiment, the number of both the welding feet 211 and the welding holes 221 is multiple, and each welding foot 211 is correspondingly arranged with each welding hole 221, so that the second conductive member 210 can be more firmly fixed to the control board 220, and at the same time, the power connection area between the second conductive member 210 and the control board 220 can be further increased to further improve the power supply efficiency and electrical connection stability between the control board 220 and the second conductive member 210.

[0033] As Figure 2 and Figure 7 shown, in one embodiment, the welding feet 211 and the second conductive member 210 are of an integrally formed structure to improve the structural compactness of the second conductive member 210.

[0034] As Figures 2 to 6As shown, in one embodiment, the power supply component 120 includes a battery cell 122 and a battery cell bracket 123. The battery cell bracket 123 is installed and fixed on the battery cell 122. The battery cell bracket 123 is used to protect and fix the battery cell 122 so that the battery cell 122 can maintain stable support for operation, greatly improving the use stability of the energy storage power supply. The support portion 121 is formed on a side surface of the battery cell bracket 123 adjacent to the control board 220, so that the support portion 121 can support the control board 220 away from the power supply component 120, and further a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210, thereby reducing the assembly difficulty and production cost of the energy storage power supply.

[0035] As Figure 5 and Figure 6 shown, in one embodiment, the battery cell bracket 123 and the support portion 121 are of an integrally formed structure to improve the structural compactness of the battery cell bracket 123.

[0036] As Figure 4 and Figure 6 shown, in one of the embodiments, a support flange 1211 is formed on a side surface of the support portion 121 adjacent to the control board 220. The support flange 1211 is used to support the control board 220. A clearance groove 1212 is also formed on a side surface of the support portion 121 adjacent to the control board 220. The clearance groove 1212 is used to accommodate the connection end where the first conductive member 110 abuts against the second conductive member 210, so that a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210. Further, during the process of installing the power management component 200 on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from first touching the positive electrode of the power supply component 100, which may cause an impact current in the energy storage power supply and damage the internal electronic circuits, components and battery cell 122. This not only greatly reduces the assembly difficulty of the energy storage power supply, but also greatly reduces the possibility of generating an impact current during the assembly process of the energy storage power supply, greatly reducing the scrap rate of the energy storage power supply, and further greatly reducing the production cost of the energy storage power supply.

[0037] As Figure 4 and Figure 6As shown, in one embodiment, the vertical height between the plane of the cell support 123 forming the support portion 121 and the top of the support flange 1211 is the first height H1, and the vertical height between the plane of the cell support 123 forming the support portion 121 and the bottom of the clearance groove 1212 is the second height H2. The first height H1 is greater than the second height H2, so that there is enough space between the first conductive member 110 and the second conductive member 210 to form a safety gap 300. During the installation of the power management component 200 on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from touching the positive electrode of the power supply component 100 first, which may cause the impact current of the energy storage power supply to damage the internal electronic circuits, components and cells 122. This not only greatly reduces the assembly difficulty of the energy storage power supply, but also greatly reduces the possibility of generating impact current during the assembly process of the energy storage power supply, resulting in a significant reduction in the scrap rate of the energy storage power supply, and thus greatly reducing the production cost of the energy storage power supply.

[0038] As Figure 6 shown, in one embodiment, the support flange 1211 and the support portion 121 are integrally formed structures to improve the structural compactness of the support portion 121.

[0039] As Figure 2 and Figure 4 shown, in one embodiment, the first conductive member 110 is a copper conductive member, an aluminum conductive member or a nickel conductive member, so that the first conductive member 110 has good electrical conductivity and structural strength, improving the use stability of the energy storage power supply.

[0040] As Figure 2 and Figure 4 shown, in one embodiment, the second conductive member 210 is a copper conductive member, an aluminum conductive member or a nickel conductive member, so that the second conductive member 210 has good electrical conductivity and structural strength, improving the use stability of the energy storage power supply.

[0041] As Figure 4 and Figure 8 shown, in one embodiment, the first conductive member 110 is formed with a buffer portion 111 to buffer the stress on the first conductive member 110, improve the overall structural strength of the first conductive member 110, greatly reduce the possibility of damage or even failure of the first conductive member 110, and thus greatly improve the use stability and service life of the energy storage power supply.

[0042] As Figure 4 and Figure 8 shown, in one embodiment, the buffer portion 111 is a buffer arc, so that the first conductive member 110 has good structural strength and improves the use stability of the energy storage power supply.

[0043] As Figure 4 shown, in one embodiment, the first conductive member 110 is detachably connected to the second conductive member 210, so that the first conductive member 110 abuts against and is electrically connected to the second conductive member 210. This not only enables the second conductive member 210 to be firmly fixed on the first conductive member 110, but also reduces the difficulty of installation and disassembly between the first conductive member 110 and the second conductive member 210, thereby greatly improving the use stability and convenience of the energy storage power supply.

[0044] As Figure 4 shown, in one embodiment, the conductive connection structure 10 further includes a fastener 400. The first conductive member 110 is provided with a first positioning hole 112, and the second conductive member 210 is provided with a second positioning hole 212 opposite to the first positioning hole 112. A nut limiting groove 1213 communicating with the avoidance groove 1212 is formed on a side surface of the support portion 121 adjacent to the control board 220, and the nut limiting groove 1213 is opposite to the second positioning hole 212. The nut limiting groove 1213 is used for installing a limiting nut 500. The fastener 400 sequentially passes through the second positioning hole 212 and the first positioning hole 112 and is screwed to the nut 500, so that the first conductive member 110 abuts against and is electrically connected to the second conductive member 210. When the fastener 400 locks and fixes the second conductive member 210 to the first conductive member 110, the head of the fastener 400 applies a pressure to the second conductive member 210 to approach the first conductive member 110, and at the same time the nut applies a pressure to the first conductive member 110 to approach the second conductive member 210. As a result, the first conductive member 110 and the second conductive member 210 can approach and abut against each other through their own deformation ability, so that the first conductive member 110 and the second conductive member 210 are electrically connected to each other, ensuring that the energy storage power supply can work stably and normally.

[0045] As Figure 4 shown, in one embodiment, the fastener 400 is a conductive fastener. The outer peripheral wall of the fastener 400 abuts against the hole wall of the first positioning hole 112 and the hole wall of the second positioning hole 212 respectively, so that the fastener 400 is electrically connected to the first conductive member 110 and the second conductive member 210 respectively, enabling the first conductive member 110 to be electrically connected to the second conductive member 210 through the fastener 400. Further, the power supply efficiency and electrical connection stability between the power management component 200 and the power supply component 100 are improved, and the use stability of the energy storage power supply is greatly improved.

[0046] As Figure 2 and Figure 4As shown, in one embodiment, the fastener 400 is a copper fastener, an aluminum fastener or a nickel fastener, so that the fastener 400 has good electrical conductivity and structural strength, further improving the power supply efficiency and electrical connection stability between the power management component 200 and the power supply component 100, and thus greatly improving the use stability of the energy storage power supply.

[0047] As Figure 2 and Figure 4 shown, in one embodiment, the fastener 400 is a bolt, a screw or a screw to improve the locking ability of the fastener 400.

[0048] As Figure 4 and Figure 7 shown, in one of the embodiments, the second conductive member 210 is mounted on a side surface of the control board 220 adjacent to the power supply member 120 to reduce the overall thickness of the power management component 200 and optimize the space utilization rate of the energy storage power supply; the control board 220 is formed with a hollow area 222, and the hollow area 222 is disposed opposite to the second conductive member 210 to facilitate the installation and disassembly operation of the fastener 400, reduce the installation and disassembly difficulty between the power management component 200 and the power supply component 100, and thus greatly reduce the convenience of use of the energy storage power supply.

[0049] As Figure 4 and Figure 7 shown, in one embodiment, the hollow area 222 and the second conductive member 210 together form a hollow groove 223 for receiving the head of the fastener 400 to further reduce the overall thickness of the power management component 200 and optimize the space utilization rate of the energy storage power supply.

[0050] As Figure 8 shown, in one of the embodiments, the first positioning hole 112 is an oval hole, so that the alignment difficulty between the first positioning hole 112 and the second positioning hole 212 is greatly reduced, the assembly difficulty between the first conductive member 110 and the second conductive member 210 is greatly reduced, and thus the convenience of use of the energy storage power supply is greatly improved.

[0051] As Figure 6 shown, in one of the embodiments, a support positioning flange 12131 is further formed on the inner peripheral wall of the nut limiting groove 1213 for limiting the nut 500, so that during the process of tightening the fastener 400, the nut 500 can be firmly limited in the nut limiting groove 1213 through the support positioning flange 12131, avoiding the phenomenon that the nut 500 rotates relative to the support portion 121 during the process of rotating and tightening the fastener 400 relative to the nut 500, so that the fastener 400 can cooperate with the nut 500 to lock and fix the first conductive member 110 and the second conductive member 210, and thus greatly improving the use stability of the energy storage power supply.

[0052] As Figure 6 shown, in one embodiment, a buffer friction portion (not shown in the figure) is fixed adjacent to one end of the support positioning flange 12131 of the nut 500, so that the buffer friction portion can buffer the pressure between the support positioning flange 12131 and the nut 500, and avoid damage or even breakage of the support positioning flange 12131 and the nut 500 due to excessive pressure. At the same time, the support positioning flange 12131 can also increase the friction force with the nut 500 through the buffer friction portion, so that the support positioning flange 12131 can more firmly limit the nut 500 in the nut limiting groove 1213, greatly reducing the possibility of the nut 500 rotating relative to the support portion 121, and thus greatly improving the use stability of the energy storage power supply.

[0053] As Figure 6 shown, in one embodiment, the support positioning flange 12131 and the support portion 121 are integrally formed to improve the structural compactness of the support portion 121.

[0054] As Figure 6 shown, in one embodiment, the number of the support positioning flanges 12131 is multiple, and the multiple support positioning flanges 12131 are uniformly arranged along the inner peripheral wall of the nut limiting groove 1213 to further improve the limiting effect of the support portion 121 on the nut 500 and greatly reduce the possibility of the nut 500 rotating relative to the support portion 121.

[0055] As Figure 6 shown, in one embodiment, the cross section of the nut 500 is polygonal, so that the support positioning flange 12131 can better limit the nut 500, effectively reducing the possibility of the nut 500 rotating relative to the support portion 121 and greatly improving the use stability of the energy storage power supply.

[0056] As Figure 4As shown, in one of the embodiments, the conductive connection structure 10 further includes an elastic washer assembly 600. The elastic washer assembly 600 is disposed on the side surface of the second conductive member 210 facing away from the first conductive member 110, and the fastener 400 passes through the elastic washer assembly 600, so that both side surfaces of the elastic washer assembly 600 are in contact with the second conductive member 210 and the fastener 400 respectively. When the fastener 400 abuts and locks the second conductive member 210 to the first conductive member 110, the head of the fastener 400 will exert a pressure on the second conductive member 210 to approach the first conductive member 110. At the same time, the nut will exert a pressure on the first conductive member 110 to approach the second conductive member 210, so that the first conductive member 110 and the second conductive member 210 can approach and abut against each other through their own deformation capabilities, thereby enabling the first conductive member 110 and the second conductive member 210 to be electrically connected to each other. The elastic washer assembly 600 can buffer the pressure exerted by the fastener 400 on the second conductive member 210, and make the fastener 400 and the second conductive member 210 receive uniform force, avoiding damage or even breakage of the fastener 400 and the second conductive member 210 due to excessive pressure or uneven force between the head of the fastener 400 and the second conductive member 210, greatly improving the use stability of the energy storage power supply. At the same time, the fastener 400 can also lock and fix the first conductive member 110 and the second conductive member 210 more firmly through the pre-tightening force and friction force generated by the elastic deformation of the elastic washer assembly 600, thereby further improving the use stability of the energy storage power supply.

[0057] As Figure 4 and Figure 9As shown, in one embodiment, the elastic washer assembly 600 includes an elastic washer 610 and a flat washer 620. The fastener 400 passes through the elastic washer 610 and the flat washer 620 in sequence. The two side surfaces of the flat washer 620 are respectively in contact with the elastic washer 610 and the second conductive member 210, and the two side surfaces of the elastic washer 610 are respectively in contact with the flat washer 620 and the fastener 400, so that the fastener 400 can increase the contact area with the second conductive member 210 through the flat washer 620, reduce the pressure per unit area, effectively disperse mechanical stress, and avoid damage or even breakage of the second conductive member 210 due to excessive local pressure, greatly improving the use stability of the energy storage power supply. The elastic washer 610 can buffer the pressure exerted by the fastener 400 on the second conductive member 210, and make the fastener 400 and the second conductive member 210 receive uniform force, avoiding damage or even breakage of the fastener 400 and the second conductive member 210 due to excessive or uneven force between the head of the fastener 400 and the second conductive member 210, and further improving the use stability of the energy storage power supply. At the same time, the fastener 400 can lock and fix the first conductive member 110 and the second conductive member 210 more firmly through the pre-tightening force and friction force generated by the elastic deformation of the elastic washer 610, and the elastic washer 610 can also compensate for the fitting gaps of the flat washer 620, the head of the fastener 400 and itself through its own elastic deformation ability, greatly improving the anti-loosening performance of the fastener 400, thereby further improving the use stability of the energy storage power supply.

[0058] As Figure 9 shown, in one embodiment, the elastic washer 610 is a plastic washer or a silicone washer, which can not only improve the buffering effect of the elastic washer 610, but also further improve the pre-tightening force and friction force between the elastic washer 610 and the fastener 400, so that the fastener 400 can lock and fix the first conductive member 110 and the second conductive member 210 more firmly, thereby improving the use stability of the energy storage power supply.

[0059] As Figure 9 shown, in one embodiment, the elastic washer 610 is formed with an avoidance opening 611 to provide sufficient elastic deformation space for the elastic washer 610 and improve the use stability of the elastic washer 610.

[0060] As Figure 2 and Figure 5As shown, in one embodiment, the conductive connection structure 10 further includes a buffer support member 700. The buffer support member 700 is disposed between the control board 220 and the power supply member 120. The two side surfaces of the buffer support member 700 are respectively in supporting contact with the control board 220 and the power supply member 120, so that the buffer support member 700 can buffer the pressure between the control board 220 and the power supply member 120, and make the force between the control board 220 and the power supply member 120 uniform, avoiding damage or even destruction of the control board 220 and the power supply member 120 due to excessive pressure or uneven force between the control board 220 and the power supply member 120, greatly improving the use stability and safety of the energy storage power supply; at the same time, the buffer support member 700 can also buffer the pressure between the support portion 121 and the control board 220, and make the force between the support portion 121 and the control board 220 uniform, avoiding damage or even destruction of the control board 220 and the support portion 121 due to excessive pressure or uneven force between the control board 220 and the support portion 121, further improving the use stability of the energy storage power supply.

[0061] As Figure 2 and Figure 5 shown, in one embodiment, the buffer support member 700 is buffer cotton or a buffer silica gel pad, so that the buffer support member 700 has good buffer support ability.

[0062] The present disclosure also provides an energy storage power supply, including the conductive connection structure 10 described in any of the above embodiments.

[0063] As Figure 11 shown, the present disclosure also provides an assembly method for an energy storage power supply, assembling the energy storage power supply described in the above embodiment, which includes some or all of the following steps: S101, fixing and electrically connecting the first conductive member 110 to the conductive end of the power supply member 120 to form a power supply assembly 100; In this embodiment, the first conductive member 110 is fixed and electrically connected to the conductive end of the power supply member 120 to form a power supply assembly 100, so that the first conductive member 110 and the power supply member 120 can be electrically connected to each other, ensuring that the power supply assembly 100 can work stably and normally.

[0065] S105. Mount the control board 220 at a preset position of the power supply component 120, and make the support portion 121 abut against and support the control board 220, so that the support portion 121 supports the control board 220 away from the power supply component 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210; In this embodiment, the control board 220 is mounted at a preset position of the power supply component 120, and the support portion 121 abuts against and supports the control board 220, so that the support portion 121 supports the control board 220 away from the power supply component 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210. Further, during the installation of the power management component 200 on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from first touching the positive electrode of the power supply component 100, which may cause an impact current in the energy storage power supply and damage the internal electronic circuits, components, and battery cells 122. This not only greatly reduces the assembly difficulty of the energy storage power supply but also significantly reduces the possibility of generating an impact current during the assembly process of the energy storage power supply, greatly reducing the scrap rate of the energy storage power supply, and thus significantly reducing the production cost of the energy storage power supply.

[0066] S107. Abut and fix the first conductive member 110 and the second conductive member 210 to electrically connect the power supply component 100 and the power management component 200.

[0073] In one embodiment, a welding hole 221 is formed at the conductive end of the control board 220, and welding feet 211 are protruded on the outer periphery of the second conductive member 210. The welding feet 211 pass through the welding hole 221, and the outer peripheral wall of the welding feet 211 is welded to the inner peripheral wall of the welding hole 221. The specific steps S1031 for welding and fixing the second conductive member 210 to the conductive end of the control board 220 include some or all of the following steps: S10311, pass the welding feet 211 through the welding hole 221; S10313, weld the outer peripheral wall of the welding feet 211 to the inner peripheral wall of the welding hole 221.

[0074] In this embodiment, the outer peripheral wall of the welding feet 211 is welded to the inner peripheral wall of the welding hole 221, so that the welding feet 211 can be firmly fixed to the inner peripheral wall of the welding hole 221, and the second conductive member 210 can be more firmly fixed to the conductive end of the control board 220, thereby ensuring that the power management assembly 200 can work stably and normally, and greatly improving the use stability of the energy storage power supply.

[0075] In one embodiment, the power supply member 120 includes a battery cell 122 and a battery cell bracket 123. The battery cell bracket 123 is mounted and fixed on the battery cell 122, and the battery cell bracket 123 is used to protect and fix the battery cell 122. Before step S103 of fixing and electrically connecting the second conductive member 210 to the conductive end of the control board 220 to form the power management component 200, the following steps are also included, either in part or in whole: S101a, mounting and fixing the battery cell bracket 123 on the battery cell 122 to form the power supply member 120.

[0076] In this embodiment, mounting and fixing the battery cell bracket 123 on the battery cell 122 to form the power supply member 120 enables the battery cell bracket 123 to fix and protect the battery cell 122, ensuring that the power supply component 100 can maintain stable and normal operation, thereby greatly improving the usage stability of the energy storage power supply.

[0077] In one embodiment, on a side surface of the support portion 121 adjacent to the control board 220, an avoidance groove 1212 is further formed. The avoidance groove 1212 is used to accommodate the connection end of the first conductive member 110 abutting against the second conductive member 210. Before step S105 of mounting the control board 220 at a preset position of the power supply member 120 and making the support portion 121 abut against and support the control board 220 so that the support portion 121 supports the control board 220 away from the power supply member 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210, the method for organizing the energy storage power supply further includes the following steps, either in part or in whole: S1033, mounting the connection end of the first conductive member 110 abutting against the second conductive member 210 in the avoidance groove 1212.

[0078] In this embodiment, mounting the connection end of the first conductive member 110 abutting against the second conductive member 210 in the avoidance groove 1212 enables the first conductive member 110 to be away from the second conductive member 210, so that a safety gap 300 can be formed between the first conductive member 110 and the second conductive member 210.

The specific steps S105 of mounting the control board 220 at a preset position of the power supply member 120 and making the support portion 121 abut against and support the control board 220 so that the support portion 121 supports the control board 220 away from the power supply member 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210 include the following steps, either in part or in whole: S1051, Install the control board 220 at a preset position of the power supply component 120, and make the support flange 1211 abut and support the control board 220, so that the support flange 1211 supports the control board 220 away from the power supply component 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210.

[0080] In this embodiment, the control board 220 is installed at a preset position of the power supply component 120, and the support flange 1211 abuts and supports the control board 220, so that the support flange 1211 supports the control board 220 away from the power supply component 120, forming a safety gap 300 between the first conductive member 110 and the second conductive member 210. Furthermore, the first conductive member 110 can be far away from the second conductive member 210, preventing the positive electrode of the power management component 200 from touching the positive electrode of the power supply component 100 first during the installation of the power management component 200 on the power supply component 100, resulting in an impact current in the energy storage power supply and damaging the internal electronic circuits, components and battery cells 122 of itself.

[0081] In one embodiment, the conductive connection structure 10 further includes a fastener 400. The first conductive member 110 is provided with a first positioning hole 112, and the second conductive member 210 is provided with a second positioning hole 212 opposite to the first positioning hole 112. A nut limiting groove 1213 communicating with the avoidance groove 1212 is formed on a side surface of the support portion 121 adjacent to the control board 220, and the nut limiting groove 1213 is opposite to the second positioning hole 212.

[0083] S1075. Rotate the fastener 400 relative to the nut 500 in the fastening direction until the second conductive member 210 abuts and is fixed to the first conductive member 110.

[0084] In this embodiment, rotate the fastener 400 relative to the nut 500 in the fastening direction until the second conductive member 210 abuts and is fixed to the first conductive member 110. When the fastener 400 locks and fixes the first conductive member 110 and the second conductive member 210, the head of the fastener 400 will apply a pressure to the second conductive member 210 to approach the first conductive member 110, and at the same time, the nut will apply a pressure to the first conductive member 110 to approach the second conductive member 210, so that the first conductive member 110 and the second conductive member 210 can approach and abut against each other through their own deformation capabilities, and then the first conductive member 110 can be electrically connected to the second conductive member 210, ensuring that the energy storage power supply can work stably and normally, thus greatly improving the use stability of the energy storage power supply.

[0085] In one embodiment, the conductive connection structure 10 further includes an elastic washer assembly 600. The elastic washer assembly 600 is disposed on the side surface of the second conductive member 210 facing away from the first conductive member 110, and the fastener 400 passes through the elastic washer assembly 600, so that the two side surfaces of the elastic washer assembly 600 respectively abut against the second conductive member 210 and the fastener 400. Before the step S1073 of passing the fastener 400 through the second positioning hole 212 and the first positioning hole 112 in sequence and screwing it to the nut 500, the assembly method of the energy storage power supply further includes some or all of the following steps: S1071a. Place the elastic washer assembly 600 at a preset position on the second conductive member 210 and set it opposite to the second positioning hole 212. In this embodiment, place the elastic washer assembly 600 at a preset position on the second conductive member 210 and set it opposite to the second positioning hole 212, so as to facilitate passing the fastener 400 through the elastic washer assembly 600 and the second positioning hole 212 in sequence, greatly reducing the assembly difficulty of the energy storage power supply.

[0086] S1071c. Pass the fastener 400 through the elastic washer assembly 600, the second positioning hole 212 and the first positioning hole 112 in sequence and screw it to the nut 500.

[0087] In this embodiment, the fastener 400 is sequentially passed through the elastic washer assembly 600, the second positioning hole 212, and the first positioning hole 112 and screwed to the nut 500, so that the elastic washer assembly 600 can buffer the pressure exerted by the fastener 400 on the second conductive member 210, and make the fastener 400 and the second conductive member 210 receive uniform force, avoiding damage or even breakage of the fastener 400 and the second conductive member 210 due to excessive pressure or uneven force between the head of the fastener 400 and the second conductive member 210, greatly improving the use stability of the energy storage power supply; at the same time, the fastener 400 can also lock and fix the first conductive member 110 and the second conductive member 210 more firmly through the pre-tightening force and frictional force generated by the elastic deformation of the elastic washer assembly 600, thereby further improving the use stability of the energy storage power supply.

[0088] In one embodiment, the elastic washer assembly 600 includes an elastic washer 610 and a flat washer 620. The fastener 400 is sequentially passed through the elastic washer 610 and the flat washer 620. The two side surfaces of the flat washer 620 are respectively in contact with the elastic washer 610 and the second conductive member 210, and the two side surfaces of the elastic washer 610 are respectively in contact with the flat washer 620 and the fastener 400. The specific steps S1071a of placing the elastic washer assembly 600 at a preset position on the second conductive member 210 include some or all of the following steps: S1071a1, place the flat washer 620 at the preset position on the second conductive member 210 and set it opposite to the second positioning hole 212; In this embodiment, the flat washer 620 is placed at the preset position on the second conductive member 210 and set opposite to the second positioning hole 212, so as to facilitate the fastener 400 to sequentially pass through the flat washer 620 and the second positioning hole 212. At the same time, the fastener 400 can increase the contact area with the second conductive member 210 through the flat washer 620, reduce the unit area pressure, effectively disperse the mechanical stress, and avoid damage or even breakage of the second conductive member 210 due to excessive local pressure, greatly improving the use stability of the energy storage power supply.

[0089] S1071a3, place the elastic washer 610 at the preset position on the flat washer 620 and set it opposite to the second positioning hole 212.

[0090] In this embodiment, an elastic washer 610 is placed at a preset position of a flat washer 620 and is disposed opposite to the second positioning hole 212, so as to facilitate the fastener 400 to sequentially pass through the elastic washer 610, the second positioning hole 212, and the first positioning hole 112. Moreover, the elastic washer 610 can buffer the pressure exerted by the fastener 400 on the second conductive member 210 and make the fastener 400 and the second conductive member 210 receive uniform force, avoiding damage or even breakage of the fastener 400 and the second conductive member 210 due to excessive pressure or uneven force between the head of the fastener 400 and the second conductive member 210, and further improving the use stability of the energy storage power supply. At the same time, the fastener 400 can more firmly lock and fix the first conductive member 110 and the second conductive member 210 through the pre-tightening force and frictional force generated by the elastic deformation of the elastic washer 610, and the elastic washer 610 can also compensate for the fitting gaps of the flat washer 620, the head of the fastener 400, and itself through its own elastic deformation ability, greatly improving the anti-loosening performance of the fastener 400, thereby further improving the use stability of the energy storage power supply.

[0091] Compared with the prior art, the present disclosure has at least the following advantages: For the above-mentioned energy storage power supply, since the control board 220 is installed at a preset position of the power supply component 120 so that the first conductive member 110 and the second conductive member 210 are disposed opposite to each other; a support portion 121 is formed on a side surface of the power supply component 120 adjacent to the control board 220, and the support portion 121 is used to support the control board 220 away from the power supply component 120 so that a safety gap 300 is formed between the first conductive member 110 and the second conductive member 210. During the installation of the power management component 200 on the power supply component 100, the second conductive member 210 can avoid direct contact with the first conductive member 110 through the safety gap 300, preventing the positive electrode of the power management component 200 from first touching the positive electrode of the power supply component 100 and causing an impact current in the energy storage power supply to damage the internal electronic circuits, components, and battery cells 122 of itself. This not only greatly reduces the assembly difficulty of the energy storage power supply, but also greatly reduces the possibility of generating an impact current during the assembly process of the energy storage power supply, greatly reducing the scrap rate of the energy storage power supply, and further greatly reducing the production cost of the energy storage power supply.
