Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage devices, and more particularly to an energy storage power supply. BACKGROUND

[0002] In related technologies, the total positive terminal and the total negative terminal of the battery pack of the energy storage power supply are usually distributed on two surfaces opposite to each other of the battery pack. In order to facilitate electrical connection with the BMS, the total positive terminal is usually transferred to the plane where the total negative terminal is located or the total negative terminal is transferred to the plane where the total positive terminal is located by using a jumper bar. However, since the jumper bar needs to span the two surfaces opposite to each other of the battery pack, the distance is relatively long, and the jumper bar is prone to displacement under stress during installation and welding, thereby causing poor welding and resulting in scrapping of the battery pack. CONTENT OF THE UTILITY MODEL

[0003] The present application provides an energy storage power supply to solve at least one of the above technical problems.

[0004] The energy storage power supply of the present application comprises:

[0005] a battery pack, the battery pack comprising a plurality of battery cells and a bracket, the plurality of battery cells being installed in the bracket, a total positive terminal of the battery pack being located at a first surface of the bracket, and a total negative terminal of the battery pack being located at a second surface of the bracket, the first surface and the second surface being oppositely arranged, a third surface of the bracket being provided with a limiting groove, and the third surface connecting the first surface and the second surface;

[0006] a jumper bar, the jumper bar being at least partially arranged in the limiting groove, and guiding one of the total positive terminal or the total negative terminal to the surface where the other of the total positive terminal or the total negative terminal is located, the limiting groove limiting the position of the jumper bar to ensure the connection accuracy of the jumper bar.

[0007] The energy storage power supply provided by the present application can assist in fixing the jumper bar during installation by arranging the limiting groove on the outer surface of the bracket, and can effectively prevent the jumper bar from being displaced under stress during installation and welding, thereby facilitating the welding quality of the jumper bar and reducing the scrapping rate of the energy storage power supply.

[0008] In some embodiments, a bone site is further arranged on the bracket, the bone site being located on both sides of the jumper bar and arranged at the edge of the limiting groove.

[0009] In this way, the bone site can effectively prevent the jumper bar from colliding with the battery cell electrode or other electrical connecting members to cause short circuit, thereby improving product safety.

[0010] In some embodiments, the jumper row comprises a jumper portion and an end portion arranged at one end of the jumper portion, the end portion being connected to the total positive terminal or the total negative terminal of the battery pack, and the jumper portion being arranged at least partially in the limiting groove.

[0011] In this way, since the end portion needs to be electrically connected to the electrode of the battery cell, the use of the limiting groove to limit the jumper portion facilitates the arrangement of the limiting groove and avoids interference of the limiting groove with the electrical connection between the end portion and the electrode.

[0012] In some embodiments, the depth of the limiting groove is greater than or equal to half the thickness of the jumper portion.

[0013] In this way, the limiting effect of the limiting groove on the jumper portion can be avoided due to the limiting groove being too shallow.

[0014] In some embodiments, the jumper row further comprises a first fixing portion arranged at the other end of the jumper portion, and the support is provided with a glue position and a second fixing portion, when the first fixing portion is fixed on the second fixing portion, the glue position presses the side surface of the first fixing portion to limit rotation or movement of the first fixing portion.

[0015] In this way, when the first fixing portion is fixed, the force acting on the first fixing portion can be directly transmitted to the glue position and cancelled out, thereby avoiding displacement of the first fixing portion due to the force.

[0016] In some embodiments, when the first fixing portion is fixed on the second fixing portion, the height of the glue position is lower than the height of the top surface of the first fixing portion.

[0017] In this way, while ensuring that the glue position can limit the first fixing portion, the glue position is prevented from interfering with the fixing of the first fixing portion due to being too long.

[0018] In some embodiments, the glue position is a plurality of protrusions arranged around the first fixing portion at intervals.

[0019] In this way, the first fixing portion can be better limited in its installation area, and displacement of the first fixing portion due to force can be avoided.

[0020] In some embodiments, the limiting groove extends along the axial direction of the battery cell.

[0021] In this way, the limiting groove can better fix the jumper row, which is conducive to preventing the jumper row from moving laterally.

[0022] In some embodiments, the support is provided with a first positioning portion, and the jumper row is provided with a second positioning portion matched with the first positioning portion, and the first positioning portion and the second positioning portion can further limit the jumper row.

[0023] Therefore, the first positioning part and the second positioning part can further limit the jumper row, and avoid displacement of the jumper row to cause the energy storage power supply to be scrapped.

[0024] In some embodiments, the first positioning part is a positioning column, and the second positioning part is a positioning hole matched with the positioning column.

[0025] Therefore, the positioning column and the positioning hole are simple to process and convenient to match and install.

[0026] Additional aspects and advantages of the embodiments disclosed herein will be set forth in part in the description that follows, and in part will become apparent to those skilled in the art upon examination of the following and / or can be learned by practice of the embodiments disclosed herein.

[0040] Please refer to Figure 1 The energy storage power supply 100 of the embodiment of the present application includes a battery pack 10 and a jumper row 20. The battery pack 10 includes a plurality of battery cells 11 and a bracket 12. The plurality of battery cells 11 are installed in the bracket 12. The total positive end of the battery pack 10 is at a first face of the bracket 12, and the total negative end of the battery pack 10 is at a second face of the bracket 12. The first face and the second face are oppositely arranged. A limiting groove 121 is arranged on a third face of the bracket 12, and the third face connects the first face and the second face. The limiting groove 121 is arranged on the outer surface of the bracket 12. The jumper row 20 is at least partially arranged in the limiting groove 121. The limiting groove 121 defines the position of the jumper row 20 to ensure the connection accuracy of the jumper row 20.

[0041] The energy storage power supply 100 provided by the present application can assist in fixing the jumper row 20 during installation by arranging the limiting groove 121 on the outer surface of the bracket 12. During installation and welding, the jumper row 20 can be effectively prevented from being displaced under stress, which is conducive to ensuring the welding quality of the jumper row 20 and reducing the scrap rate of the energy storage power supply 100.

[0042] Specifically, the energy storage power supply 100 is a device that can store electrical energy and release it when needed. Its main function is to provide stable and reliable power supply. When the system needs to store electrical energy, the controller will charge the battery pack, and the battery pack will convert the electrical energy into chemical energy for storage. When the system needs to use electrical energy, the controller first converts the direct current electrical energy stored in the battery pack into alternating current electrical energy, and then outputs it.

[0043] The jumper row 20 is usually made of high-conductivity metal (such as copper or aluminum) and is used to cross the space or structural members inside the battery pack 10, connect different modules or battery cells, ensure efficient transmission of current between modules, and maintain the circuit connectivity of the entire battery system.

[0044] The cross-over row 20 is a sheet metal part. The sheet metal part refers to a metal product processed by a specific sheet metal process. This process is mainly aimed at metal sheets (usually below 6mm), including a series of comprehensive cold processing processes such as shearing, punching / cutting / compounding, bending, welding, riveting, splicing, forming, etc. The sheet metal part is characterized by the same thickness of the same part. The sheet metal part has the characteristics of light weight, high strength, good electrical conductivity (can be used for electromagnetic shielding), low cost, and is suitable for mass production.

[0045] In this way, the sheet metal part usually has high tensile strength and compressive strength, which is beneficial to improve the service life of the cross-over row 20, and the sheet metal part has high processing efficiency, which is beneficial to shorten the processing cycle.

[0046] In the embodiment of the present application, the cross-over row 20 is processed and formed by shearing and bending, and burrs that may occur during processing are removed, and the sharp corner part of the cross-over row 20 is rounded, thereby preventing the cross-over row 20 from injuring the hands of the operator during assembly or maintenance.

[0047] In other embodiments, the cross-over row 20 can also be processed and formed by other sheet metal processes, such as one-time stamping forming, and the specific sheet metal process can be selected according to actual needs, which is not limited herein.

[0048] Please refer to Figure 1 and 2 In some embodiments, the battery pack 10 further includes detachably connected upper and lower supports 122 and 123. In the embodiment of the present application, the surface of the upper support 122 away from the surface of the cell 11 is a first surface, the surface of the lower support 123 away from the surface of the cell 11 is a second surface, and the side surface of the same side of the upper support 122 and the lower support 123 is a third surface. The cross-over row 20 guides the total negative end of the second surface to the total positive end of the first surface.

[0049] A plurality of cells 11 are installed between the upper and lower supports 122 and 123, and the limiting groove 121 includes a first limiting groove 1211 provided on the upper support 122 and a second limiting groove 1212 provided on the lower support 123.

[0050] Specifically, the upper support 122 includes a plurality of first positioning grooves 1221, and the lower support 123 includes a plurality of first positioning grooves 1221 corresponding to the second positioning grooves 1231, respectively. The first positioning groove 1221 is provided on the first inner wall of the upper support 122, and the second positioning groove 1231 is provided on the second inner wall of the lower support 123.

[0051] Further, the first positioning slots 1221 are in plurality, and the plurality of first positioning slots 1221 are arranged in an array, the second positioning slots 1231 are in plurality, and the plurality of second positioning slots 1231 are arranged in an array, and the second positioning slots 1231 are arranged in one-to-one correspondence with the first positioning slots 1221. In the embodiment of the present application, one second positioning slot 1231 cooperates with one first positioning slot 1221 to fix one battery cell 11 of the battery module.

[0052] In the embodiment of the present application, one end of the battery cell 11 is inserted into the first positioning slot 1221 of the upper support 122, and the other end is arranged in the second positioning slot 1231 of the lower support 123, and the cooperation of the first positioning slot 1221 and the second positioning slot 1231 realizes the fixation of the battery cell 11.

[0053] In some embodiments, the battery cell 11 can be in a sheet shape or a block shape, and correspondingly, the first positioning slot 1221 and the second positioning slot 1231 should be arranged as square slots cooperating with the battery cell 11 to ensure the stability of the battery cell 11.

[0054] In another example, the battery cell 11 can also be in a cylindrical shape, and correspondingly, the first positioning slot 1221 and the second positioning slot 1231 should be arranged as circular slots cooperating with the battery cell 11 to ensure the stability of the battery cell 11.

[0055] In other examples, the battery cell 11 can also be in other shapes, and correspondingly, the first positioning slot 1221 and the second positioning slot 1231 should be arranged as type slots cooperating with the battery cell 11 to ensure the stable placement of the battery cell 11, which is not limited here.

[0056] In some embodiments, the battery cell 11 has two electrodes 111, and the two electrodes 111 can also be arranged on opposite sides of the battery cell 11, respectively, and when arranged in an array, the electrodes 111 are arranged on both sides of the battery pack 10, respectively, to facilitate the connection between the battery cells 11.

[0057] In some embodiments, the upper support 122 includes a plurality of first connecting columns 1222, the lower support 123 includes a plurality of second connecting columns 1232, and the first connecting columns 1222 are connected with the second connecting columns 1232 when the upper support 122 is connected with the lower support 123.

[0058] In this way, the first connecting columns 1222 and the second connecting columns 1232 are used for the connection of the upper support 122 and the lower support 123, and the arrangement of the first connecting columns 1222 is beneficial to improve the structural strength of the upper support 122, and the arrangement of the second connecting columns 1232 is beneficial to improve the structural strength of the lower support 123.

[0059] In some embodiments, the first connecting columns 1222 are arranged on the first inner wall of the upper support 122 in a multi-row and multi-column array. Similarly, the second connecting columns 1232 are arranged on the second inner wall of the lower support 123 in a multi-row and multi-column array.

[0060] Further, the first connecting columns 1222 and the upper support 122 are integrally formed, and the second connecting columns 1232 and the lower support 123 are integrally formed.

[0061] In the embodiments of the present application, the plurality of first connecting columns 1222 and the plurality of second connecting columns 1232 are arranged at the gaps of the arrayed battery cells 11, which is conducive to reducing the volume of the battery pack 10 and reducing the risk of deformation of the battery cells 11 due to mutual extrusion caused by collision.

[0062] In some embodiments, since the first connecting columns 1222 and the second connecting columns 1232 are relatively long, in order to improve the structural strength, the bottom shell is further provided with first reinforcing ribs 1223, which are triangular or trapezoidal, one end of the first reinforcing ribs 1223 is connected to the first inner wall, and the other end of the first reinforcing ribs 1223 is connected to the first connecting columns 1222. Similarly, the top shell is further provided with second reinforcing ribs 1233, which are triangular or trapezoidal, one end of the second reinforcing ribs 1233 is connected to the second inner wall, and the other end of the second reinforcing ribs 1233 is connected to the second connecting columns 1232.

[0063] Further, each first connecting column 1222 is connected to a plurality of first reinforcing ribs 1223, and similarly, each second connecting column 1232 is connected to a plurality of second reinforcing ribs 1233. In the embodiments of the present application, each first connecting column 1222 is connected to at least four first reinforcing ribs 1223, and similarly, each second connecting column 1232 is connected to at least four second reinforcing ribs 1233.

[0064] Further, in order to further strengthen the structural strength of the first connecting columns 1222, the first reinforcing ribs 1223 between two adjacent first connecting columns 1222 arranged on the outer side of the battery module are connected, and similarly, the second reinforcing ribs 1233 between two adjacent second connecting columns 1232 arranged on the outer side of the battery module are also connected.

[0065] Please refer to Figure 3 In some embodiments, the support 12 is further provided with a bone site 124, which is located on both sides of the bridging row 20 and is arranged at the edge of the limiting groove 121.

[0066] Therefore, the bone site 124 can effectively prevent the cross-connection row 20 from short-circuiting with the electrode 111 of the battery cell 11 or other electrical connections, thereby improving product safety.

[0067] Specifically, in the embodiments of the present application, the bone site 124 is in a long strip shape along the edge of the limiting groove 121. The number of bone sites 124 is four, two of which are arranged on both sides of the first limiting groove 1211, and the other two are arranged on both sides of the second limiting groove 1212.

[0068] Further, the end face of the bone site 124 away from the bracket 12 is in a circular arc shape, which can prevent the bone site 124 from scratching the hands of the operator during installation, and also has a guiding effect, thereby facilitating the installation of the cross-connection row 20.

[0069] Please refer to Figure 4 In some embodiments, the cross-connection row 20 includes a cross-connection part 21 and an end part 22 arranged at one end of the cross-connection part 21, the end part 22 is connected to the total positive end or the total negative end of the battery pack 10, and the cross-connection part 21 is at least partially arranged in the limiting groove 121.

[0070] Therefore, since the end part 22 needs to be electrically connected to the electrode 111 of the battery cell 11, the limiting groove 121 is used to limit the cross-connection part 21, which is more convenient for the arrangement of the limiting groove 121, and can also avoid the interference of the limiting groove 121 with the electrical connection between the end part 22 and the electrode 111.

[0071] Specifically, in the embodiments of the present application, the number of end parts 22 is two, which are respectively connected to the two ends of the cross-connection part 21. The end part 22 is perpendicular to the cross-connection part 21, and the two cross-connection parts 21 are arranged in the same direction.

[0072] Further, the end part 22 is used to be electrically connected to the total positive end or the total negative end of the battery pack 10, and the connection mode includes but is not limited to fastener connection, welding, etc. In the embodiments of the present application, the total positive end or the total negative end is usually one or more electrodes 111 of a plurality of battery cells 11, and the end part 22 is provided with a laser welding hole, which is electrically connected to the electrode 111 as the total positive end or the total negative end through laser welding.

[0073] Please refer to Figure 3 and Figure 4 In some embodiments, the depth of the limiting groove 121 is greater than or equal to half the thickness of the cross-connection part 21.

[0074] Therefore, the limiting effect of the limiting groove 121 on the cross-connection part 21 can be avoided.

[0075] Specifically, the depth greater than or equal to half the thickness of the jumper row 20 can form sufficient side wall restraint to prevent the jumper row 20 from lateral displacement when vibrating, impacting or thermal expansion, ensuring long-term stability of the electrode 111 connection. The deeper limiting groove 121 can guide the precise embedding of the jumper row 20, reducing the error (such as deviation or tilt) of manual or automated assembly, and improving batch production consistency. In the case of falling or extrusion, the side wall of the limiting groove 121 can also absorb part of the impact energy, protecting the connection structure of the jumper row 20 and the battery cell 11.

[0076] In addition, the bracket 12 is usually made of insulating and high-temperature resistant engineering plastic, and the deeper limiting groove 121 can reduce the area of the jumper row 20 exposed to the external environment, reducing the risk of short circuit or arc.

[0077] In other embodiments, the limiting groove 121 can be designed in a stepped or segmented manner to accommodate the mixed use of jumper rows 20 of different thicknesses.

[0078] In other embodiments, the limiting groove 121 entrance can also be designed as a horn mouth or a guide slope to achieve automatic centering insertion of the jumper row 20 and improve assembly efficiency.

[0079] Please refer to Figure 5 In some embodiments, the bracket 12 is provided with a glue position 125 and a second fixing part 126, and when the first fixing part 23 is fixed on the second fixing part 126, the glue position 125 presses the side of the first fixing part 23 to limit the rotation or movement of the first fixing part 23.

[0080] In this way, when the first fixing part 22 is fixed, the force received by the first fixing part 23 can be directly transmitted to the glue position 125 and cancelled out, thereby avoiding displacement of the first fixing part 23 due to force.

[0081] Specifically, in the embodiments of the present application, the first fixing part 23 needs to be fixed on the second fixing part 126 by a fastener, and when the fastener is tightened, the first fixing part 23 will be subjected to a certain degree of rotational force. Since the end part 22 at the other end of the jumper row 20 is electrically connected to the electrode 111 of the battery cell 11 by welding, the structural strength is low, the distance between the welding position and the position where the rotational force of the fastener is generated is long, and the torque is too large, which can easily cause the jumper row 20 to displace due to force, resulting in failure of the welded end connection. The design of the aluminum row on both sides of the lock screw, and the glue position 125 pressing the side of the first fixing part 23, can make the rotational force received by the aluminum row directly converted into the glue position 125 at a short distance; thereby avoiding the failure of the welded end connection of the jumper row 20.

[0082] Further, the jumper row 20 first fixing part 23 is fixed by the second fixing part 126, and the glue position 125 presses against the side of the first fixing part 23. The double constraints can effectively prevent the first fixing part 23 of the jumper row 20 from rotating or moving due to factors such as vibration and temperature change during the operation of the battery pack 10, ensuring that the connection between the jumper row 20 and the electrode 111 of the battery cell 11 remains stable and reliable at all times, and reducing the risk of poor contact, heating and other failure caused by loose connection.

[0083] In addition, during installation, the design of the glue position 125 provides a clear reference for the positioning of the first fixing part 23 of the jumper row 20, which helps to improve installation efficiency and reduce installation difficulty. When maintaining, the stable connection state of the jumper row 20 also facilitates detection and repair, reducing the troubleshooting time caused by connection problems.

[0084] It should be noted that the material of the glue position 125 should have good elasticity, wear resistance and aging resistance to ensure that it can continuously and effectively press against the first fixing part 23 of the jumper row 20 during long-term use. At the same time, the elasticity of the glue position 125 should be moderate, which can provide enough pressure to limit the movement of the first fixing part 23, and will not cause the first fixing part 23 of the jumper row 20 to deform or be damaged due to excessive pressure.

[0085] In some embodiments, the height of the glue position 125 is lower than the height of the top surface of the first fixing part 23 when the first fixing part 23 is fixed on the second fixing part 126.

[0086] In this way, while ensuring that the glue position 125 can limit the first fixing part 23, the excessively long glue position 125 is avoided from interfering with the fixation of the first fixing part 23.

[0087] Specifically, the height of the glue position 125 is lower than the top surface of the first fixing part 23, so that when installing the first fixing part 23 of the jumper row 20, the glue position 125 will not block the alignment of the first fixing part 23 and the second fixing part 126 and the insertion of the fastener. The operator can place the first fixing part 23 on the second fixing part 126 more smoothly, reducing the installation difficulty and improving the installation efficiency. When it is necessary to disassemble the jumper row 20 for maintenance or replacement, since the glue position 125 is lower than the top surface of the first fixing part 23, the disassembly tool (such as a screwdriver, wrench, etc.) can more easily contact the first fixing part 23, facilitating the disassembly operation and reducing the disassembly difficulty caused by the obstruction of the glue position 125.

[0088] In some embodiments, the glue position 125 is a plurality of protrusions arranged around the first fixing part 23 at intervals.

[0089] In this way, the first fixing part 23 can be better limited within its installation area, avoiding its displacement under stress.

[0090] Specifically, the glue positions 125 are a plurality of protrusions arranged at intervals around the first fixed part 23, which can press the side of the first fixed part 23 from different directions. Compared with a single glue position 125 structure, this multi-point pressing mode can make the force on the first fixed part 23 more uniform, effectively limit the rotation and movement of the first fixed part 23 in all directions, and greatly improve the stability of the first fixed part 23 of the cross-connection row 20. Moreover, uniform stress can avoid deformation of the first fixed part 23 due to excessive local stress, ensure that the electrical connection between the cross-connection row 20 and the electrode 111 of the battery cell 11 always remains in good condition, and reduce problems such as heating and increased resistance caused by poor contact.

[0091] Further, compared with the overall glue position 125, the plurality of protrusions arranged at intervals can reduce the amount of glue position 125 material and reduce production costs. At the same time, due to the relatively small protrusion structure, it is also easier to achieve precise molding during the manufacturing process. Smaller glue position 125 structure has shorter cooling time in manufacturing processes such as injection molding, which can improve production efficiency and further reduce production costs.

[0092] In other embodiments, the protrusions arranged at intervals have a certain flexibility and can adapt to different shapes and sizes of the first fixed part 23 of the cross-connection row 20. Even if the shape of the first fixed part 23 is not completely regular, the protrusions can achieve effective limiting effect through contact with different parts of the first fixed part 23.

[0093] It should be noted that in order to ensure uniform pressing of the first fixed part 23, the height of the plurality of protrusions should be as consistent as possible. If the heights of the protrusions are inconsistent, it may cause uneven stress on the first fixed part 23, affecting the limiting effect. The shape of the protrusion should be designed reasonably, which should be able to provide enough pressing force and avoid excessive pressure concentration on the first fixed part 23. Common protrusion shapes include cylindrical, square, etc., which can be selected according to actual conditions.

[0094] In some embodiments, the limiting groove 121 extends in the axial direction of the battery cell 11.

[0095] In this way, the limiting groove 121 can better fix the cross-connection row 20, which is conducive to preventing the cross-connection row 20 from moving laterally.

[0096] Specifically, the limiting groove 121 extending in the axial direction of the battery cell 11 provides a longitudinal fixing effect for the cross-connection row 20. The longitudinal limiting groove 121 can prevent the cross-connection row 20 from moving in the vertical direction, ensuring that the cross-connection row 20 always maintains the correct position, thereby ensuring the connection stability of the cross-connection row 20 and the electrode 111 of the battery cell 11.

[0097] When installing the jumper row 20, the axially extending limiting groove 121 can serve as an installation guide, enabling the operator to more accurately place the jumper row 20 in the designated position. This helps to improve installation efficiency and reduce installation errors.

[0098] Referring to Figure 6 and Figure 7 In some embodiments, the bracket 12 is provided with a first positioning part 127, and the jumper row 20 is provided with a second positioning part 24 that cooperates with the first positioning part 127. The cooperation of the first positioning part 127 and the second positioning part 24 can further limit the jumper row 20.

[0099] In this way, the cooperation of the first positioning part 127 and the second positioning part 24 can further limit the jumper row 20, preventing displacement and causing the energy storage power supply 100 to be scrapped.

[0100] Specifically, the first positioning part 127 is arranged on the end part 22 and the first fixing part 23, and the second positioning part 24 is arranged on the first face and the second face. The limiting groove 121 itself has preliminarily limited the position of the jumper row 20, and the cooperation of the first positioning part 127 and the second positioning part 24 is equivalent to adding a second positioning method. This double positioning mechanism can more accurately determine the position of the jumper row 20, ensuring that the connection between the jumper row 20 and the electrode 111 of the battery cell 11 is more accurate, and reducing problems such as poor contact caused by positioning deviation.

[0101] During the use of the battery pack 10, the jumper row 20 may be affected by external forces such as vibration and impact. The cooperation of the first positioning part 127 and the second positioning part 24 can increase the connection firmness between the jumper row 20 and the bracket 12, preventing the jumper row 20 from loosening or shifting due to external forces, and ensuring the long-term stable operation of the battery pack 10.

[0102] It should be noted that the first positioning part 127 and the second positioning part 24 should be accurately matched in size to ensure that they can fit tightly. If the sizes do not match, it may cause inaccurate positioning or difficulty in cooperation.

[0103] In some embodiments, the first positioning part 127 is a positioning column, and the second positioning part 24 is a positioning hole that cooperates with the positioning column.

[0104] In this way, the positioning column and the positioning hole are simple to process and easy to cooperate and install.

[0105] Specifically, in the process of inserting the positioning column into the positioning hole, the outer contour of the positioning column closely fits the inner wall of the positioning hole, providing clear guidance for the installation of the jumper row 20, ensuring that the jumper row 20 can be accurately and correctly installed to the predetermined position, greatly improving the positioning accuracy and reducing problems such as poor connection caused by installation deviation. The cooperation between the positioning column and the positioning hole has high stability, and once it is cooperated in place, the jumper row 20 is not easy to deviate, thereby ensuring the reliable connection between the jumper row 20 and the electrode 111 of the battery cell 11 and improving the overall performance of the battery pack 10.

[0106] Further, the positioning column and the positioning hole have obvious shape characteristics, and the operator can quickly and accurately identify the positions of the positioning column and the positioning hole when installing the jumper row 20, facilitating the alignment operation, reducing the installation difficulty, and improving the installation efficiency.
