Description

[0002] In the field of lithium ion battery production and manufacturing, square aluminum single cells are widely used in many scenarios such as new energy vehicles and energy storage systems due to their excellent performance.

[0003] At present, the industry generally adopts the method of welding positive and negative BusBar (busbar) to build a connection path for the electrical performance test of square aluminum single cells. However, this process has many drawbacks: first, the welding process of square aluminum single cell BusBar is complex, which seriously prolongs the detection time. Moreover, the high temperature and high pressure generated during welding may damage the cell shell, causing leakage risk at the welded part, which not only reduces the quality of the cell, but also may cause serious safety accidents, bringing great safety hazards to production; second, during the detection process, the cell is prone to external short circuit due to the lack of special tool to restrain the cell, which not only makes the detection result deviate and cannot truly reflect the electrical performance of the cell, but also may damage the detection equipment, increasing the detection cost and equipment maintenance difficulty; third, the positive and negative BusBar cannot be removed after welding, which is a consumable product, greatly increasing the detection cost. At the same time, the cell cannot be normally returned to the warehouse for re-detection or use after welding due to the removal of the BusBar, resulting in a large amount of cell waste, which is contrary to the current trend of green production and cost reduction and efficiency improvement in the industry.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0026] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the connection between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0027] Please refer to Figures 1 to 4 The embodiments of the present application provide an auxiliary detection tool 100 for an electric core, which comprises a detection clamp 10 and two overcurrent pole columns 20 detachably connected with the detection clamp 10. The detection clamp 10 is used for clamping the outer wall of an electric core 200 to be detected and exposing the top of the electric core 200 to be detected. The two overcurrent pole columns 20 abut against the positive pole column and the negative pole column of the electric core 200 to be detected, respectively, and are electrically connected with the overcurrent device of a detection device. The auxiliary detection tool 100 for the electric core can solve the problems of long detection time, easy liquid leakage and short circuit, and the electric core cannot be used again in the electric performance test of the existing square aluminum single electric core by the busbar welding method.
[0028] It should be noted that, as Figures 1 to 4As shown, the battery auxiliary detection tool 100 includes a detection clamp 10 and two overcurrent poles 20, and the detection clamp 10 and the overcurrent poles 20 are detachably connected, which facilitates the assembly and disassembly of the tool, and also facilitates the replacement or maintenance of parts in different situations.
[0029] The detection clamp 10 is used to fix the battery to be detected 200, and the specific way is to clamp the outer wall of the battery to be detected 200, and at the same time, the top of the battery to be detected 200 is exposed. This design is to facilitate the contact with the positive and negative poles at the top of the battery to be detected 200, and to provide convenience for the subsequent detection operation.
[0030] On the basis of the restraint of the detection clamp 10 to the battery to be detected 200, the two overcurrent poles 20 correspondingly abut on the positive and negative poles of the battery to be detected 200. Through this abutting mode, the electrical connection between the two overcurrent poles 20 and the battery to be detected 200 can be realized, and the end of the two overcurrent poles 20 away from the battery to be detected 200 is also electrically connected with the overcurrent device of the detection equipment, thereby forming a complete detection circuit, so that the battery to be detected 200 can be tested for electrical performance by the overcurrent device of the detection equipment.
[0031] The existing square aluminum single battery is tested for electrical performance by bus welding. Because the welding bus needs a certain operation time, and some processing and waiting may be required after welding, the whole detection process takes a long time. The battery auxiliary detection tool 100 provided by the present application adopts the abutting mode of the detachable overcurrent poles 20 and the electrode poles of the battery to be detected 200, without welding operation, which greatly reduces the preparation time before detection, thereby shortening the overall detection time and improving the detection efficiency.
[0032] The existing square aluminum single battery is tested for electrical performance by bus welding. Because the welding process may cause certain damage to the structure of the battery to be detected 200, affecting the sealing of the battery to be detected 200, and thus causing the leakage of the battery to be detected 200. The battery auxiliary detection tool 100 provided by the present application does not need welding operation, which avoids the damage to the structure of the battery to be detected 200, maintains the sealing of the battery to be detected 200 and the integrity of the original structure, effectively reduces the possibility of leakage, and improves the safety and reliability of the detection process.
[0033] The existing square aluminum single cell adopts busbar welding method for electrical performance test. Because there is lack of special tool for restraining the cell during the detection process, the cell is prone to external short circuit, which not only makes the detection result deviate and cannot truly reflect the electrical performance of the cell, but also may damage the detection equipment, increase the detection cost and equipment maintenance difficulty. The cell auxiliary detection tool 100 provided in the application restrains the cell to be detected 200 during the whole test process through the detection clamp 10, effectively reduces the possibility of short circuit, and improves the safety and reliability of the detection process.
[0034] The existing square aluminum single cell adopts busbar welding method for electrical performance test. Because the welding method causes permanent connection and structural change to the cell to be detected 200, the cell to be detected 200 cannot be used for other purposes after detection, causing waste of resources. The cell auxiliary detection tool 100 provided in the application does not cause permanent structural change to the cell to be detected 200 due to the detection clamp 10 and the overcurrent pole 20, so that the cell to be detected 200 can still be used after completing the electrical performance test, saving resources and reducing detection cost.
[0035] As an implementable manner, as shown in Figures 1 to 3 The detection clamp 10 includes a base 11 and at least two baffles 12 detachably connected with the base 11, wherein the two baffles 12 are respectively arranged on opposite sides of the cell to be detected 200, and the base 11 is provided with a plurality of connection points, and the baffle 12 is selectively connected with any one connection point.
[0036] It should be noted that, as shown in Figures 1 to 3 The detection clamp 10 includes a base 11 and at least two baffles 12, and the base 11 and the baffle 12 are in detachable connection, so that the detection clamp 10 is more flexible during use, facilitating assembly and disassembly according to different needs, and facilitating maintenance and replacement of each component.
[0037] The at least two baffles 12 are used to fix the cell to be detected 200. In use, the two baffles 12 are respectively placed on opposite sides (for example, large side) of the cell to be detected 200, so as to limit the cell to be detected 200 in a certain space, play a fixing and positioning role, and ensure that the cell to be detected 200 does not move during detection, thereby ensuring the accuracy of detection.
[0038] The base 11 is provided with a plurality of connection points, which provide different position options for the installation of the baffle 12. The baffle 12 can be selectively connected to any one of the connection points of the base 11 according to actual needs. This means that the connection position of the baffle 12 on the base 11 can be adjusted according to the different sizes or shapes of the to-be-detected battery 200, so as to adapt to different specifications of the to-be-detected battery 200, greatly improving the universality of the detection clamp 10 and reducing the cost and time required for replacing different detection clamps 10 due to different specifications of the to-be-detected battery 200.
[0039] As an implementable manner, as shown in Figures 1 to 3 , the baffle 12 is in an L-shaped structure, one side plate of the L-shaped structure abuts against the outer wall of the to-be-detected battery 200, and the other side plate is detachably connected with the base 11.
[0040] It should be noted that, as shown in Figures 1 to 3 , the baffle 12 is designed in an L-shaped structure, in other words, the baffle 12 is composed of two mutually perpendicular side plates, one of which abuts against the outer wall of the to-be-detected battery 200, and the other is detachably connected with the base 11. The abutting side plate tightly fits the to-be-detected battery 200 from the side, providing lateral support and limiting for the to-be-detected battery 200, preventing the to-be-detected battery 200 from shaking or moving left and right during detection, and ensuring that the to-be-detected battery 200 is in a stable state. The other side plate is detachably connected with the base 11, which stably installs the baffle 12 on the base 11, so that the entire detection clamp 10 forms a stable structure, and the detachable connection facilitates the installation and disassembly of the baffle 12.
[0041] In addition, the L-shaped baffle 12 can fix the to-be-detected battery 200 from two directions. The side plate abutting against the outer wall of the to-be-detected battery 200 can effectively limit the movement of the to-be-detected battery 200 in the horizontal direction, and the side plate connected with the base 11 can constrain the to-be-detected battery 200 in the vertical direction through cooperation with the base 11, preventing the to-be-detected battery 200 from moving up and down. Compared with single-direction fixing, this multi-directional fixing method can more firmly hold the to-be-detected battery 200, improving the stability of the to-be-detected battery 200 during detection, thereby ensuring the accuracy of the detection result.
[0042] As an implementable manner, as shown in Figures 1 to 4 , the detection clamp 10 further comprises a fastener 13, and the baffle 12 is provided with a mounting hole, and the fastener 13 is arranged in the mounting hole and the connection point, so that the baffle 12 is detachably connected with the base 11.
[0043] It should be noted that, as shown in Figures 1 to 4As shown, the baffle plate 12 is provided with mounting holes, and the base 11 is provided with multiple connection points. The baffle plate 12 and the base 11 are connected together by passing the fasteners 13 through the mounting holes of the baffle plate 12 and the corresponding connection points of the base 11. Since this connection is achieved by the fasteners 13, the baffle plate 12 and the base 11 are in a detachable connection relationship. When it is necessary to disassemble the baffle plate 12, the baffle plate 12 can be separated from the base 11 by simply removing the fasteners 13 from the mounting holes and the connection points, which facilitates the adjustment, maintenance or replacement of parts of the clamp.
[0044] As an implementable manner, as shown in Figures 1 to 4 As shown, the multiple connection points are in communication to form a chute 111, or the multiple connection points are independently spaced apart.
[0045] It should be noted that, as shown in Figures 1 to 4 As shown in some embodiments, when the multiple connection points are in communication to form a chute 111, it means that these connection points on the base 11 are no longer isolated, but form a continuous channel. The baffle plate 12 can move along this chute 111, so that the position of the baffle plate 12 on the base 11 can be more flexibly adjusted to adapt to the fixing needs of different sizes of the battery cell 200 to be detected. For example, the side plate of the baffle plate 12 abutting against the outer wall of the battery cell 200 to be detected can be provided with a protrusion, and the shape of the protrusion is adapted to the shape of the chute 111.
[0046] In other embodiments, the multiple connection points are independently spaced apart, that is, each connection point is separated from each other with a certain spacing distance. In this case, the baffle plate 12 can only be connected to a specific position of the connection point by the fastener 13, although it is not as flexible as the chute 111 form in position adjustment, but it also has its unique advantages in some specific scenarios, such as providing more definite and stable fixing position, which is suitable for the case where the fixed position of the battery cell 200 to be detected is required to be more accurate.
[0047] As an implementable manner, as shown in Figures 1 to 4 As shown, the detection clamp 10 further comprises four columns 14 and a pole fixing assembly 15. The four columns 14 are respectively arranged around the base 11, and the through-flow pole 20 is detachably connected to the column 14 through the pole fixing assembly 15, so that the through-flow pole 20 is correspondingly arranged above the battery cell 200 to be detected.
[0048] It should be noted that, as shown in Figures 1 to 4As shown, the testing fixture 10 also includes four pillars 14 and a terminal fixing assembly 15. The four pillars 14 are respectively arranged around the base 11, serving as support and fixation. The overcurrent terminal 20 is detachably connected to the pillars 14 via the terminal fixing assembly 15. This connection method makes the installation and removal of the overcurrent terminal 20 convenient. The function of the terminal fixing assembly 15 is to stably fix the overcurrent terminal 20 to the pillars 14, and because it is a detachable connection, it is convenient to adjust the position of the overcurrent terminal 20 according to actual testing needs. After the overcurrent terminal 20 is installed on the pillars 14, its position is correspondingly set above the battery cell 200 to be tested. This setting allows the overcurrent terminal 20 to easily abut against the positive and negative terminals on the top of the battery cell 200 to be tested, thereby achieving electrical connection with the battery cell 200 to be tested and providing a path for subsequent electrical performance testing.
[0049] As an feasible approach, such as Figures 1 to 4 As shown, the electrode fixing assembly 15 includes two parallel first positioning rods 151 and two parallel second positioning rods 152. The first positioning rods 151 extend along the length direction of the battery cell 200 to be tested, and the second positioning rods 152 extend along the width direction of the battery cell 200 to be tested. The opposite ends of the first positioning rods 151 are detachably connected to the two uprights 14, and the opposite ends of the second positioning rods 152 are detachably connected to the two first positioning rods 151. The overcurrent electrode 20 is correspondingly arranged on the second positioning rod 152.
[0050] It should be noted that, as Figures 1 to 4 As shown, the electrode fixing assembly 15 includes two parallel first positioning rods 151 and two parallel second positioning rods 152. The first positioning rods 151 extend along the length of the battery cell 200 to be tested, and their opposite ends are detachably connected to the two columns 14. This means that the first positioning rods 151 can be installed at different positions on the columns 14 as needed, or can be removed when not in use, facilitating the assembly and adjustment of the testing fixture 10. The second positioning rods 152 extend along the width of the battery cell 200 to be tested, and their opposite ends are detachably connected to the two first positioning rods 151. In this way, the second positioning rods 152 are fixed on the first positioning rods 151, forming a planar frame structure together with the first positioning rods 151. The overcurrent terminals 20 are arranged one-to-one on the second positioning rod 152. Since the second positioning rod 152 and the first positioning rod 151, and the first positioning rod 151 and the column 14 are detachably connected, the position of the overcurrent terminals 20 on the horizontal plane (i.e. above the cell 200 to be tested) can be flexibly adjusted to accurately correspond to the positive and negative terminals of the cell 200 to be tested.
[0051] As an feasible approach, such asFigures 1 to 3 As shown, the first positioning rod 151 is provided with multiple locking points, and the second positioning rod 152 is selectively connected to any one of the locking points.
[0052] It should be noted that, as Figures 1 to 3 As shown, the first positioning rod 151 is provided with multiple locking points. These locking points are the positions for connecting the second positioning rod 152. The second positioning rod 152 can be selectively connected to any one of the locking points of the first positioning rod 151 according to actual needs. That is, the installation position of the second positioning rod 152 on the first positioning rod 151 is not fixed, but can be selected from multiple different positions. In this way, the relative position of the second positioning rod 152 on the first positioning rod 151 can be changed, and the position of the overcurrent pole column 20 installed on the second positioning rod 152 can be adjusted to adapt to the electrode column positions of different specifications of the to-be-detected battery cell 200.
[0053] As an implementable manner, as Figures 1 to 3 As shown, the pole fixing assembly 15 further includes a locking piece 153, and the second positioning rod 152 is provided with a locking hole. The locking piece 153 is arranged in the locking hole and the locking point, so that the second positioning rod 152 is detachably connected with the first positioning rod 151.
[0054] It should be noted that, as Figures 1 to 3 As shown, the second positioning rod 152 is provided with a locking hole, and the first positioning rod 151 is provided with multiple locking points. When the second positioning rod 152 needs to be connected to the first positioning rod 151, the locking piece 153 is inserted into the locking hole of the second positioning rod 152 and the corresponding locking point of the first positioning rod 151, so as to realize the connection between the second positioning rod 152 and the first positioning rod 151. Since the connection is realized by the locking piece 153, this connection mode is detachable. When the position of the second positioning rod 152 on the first positioning rod 151 needs to be adjusted, or the detection clamp 10 needs to be maintained or parts need to be replaced, the locking piece 153 can be taken out, so that the second positioning rod 152 can be conveniently detached.
[0055] As an implementable manner, as Figures 1 to 3 As shown, the multiple locking points are communicated with each other to form a through groove 1511, or the multiple locking points are independently arranged in a spaced manner.
[0056] It should be noted that, as Figures 1 to 3As shown, in some embodiments, the plurality of locking points on the first positioning rod 151 are not isolated from each other, but are connected together to form a continuous through slot 1511. Such a design allows the second positioning rod 152 to be more flexible in adjusting the position when installed, and in theory, the installation position can be arbitrarily selected within the range covered by the through slot 1511, thereby more finely adjusting the position of the overcurrent pole 20 to adapt to different sizes and electrode pole positions of the battery to be detected 200.
[0057] In other embodiments, the locking points on the first positioning rod 151 are separate from each other, with a certain interval between them. Each locking point is an independent connection position, and the second positioning rod 152 can only choose these specific interval positions for connection. Although this design is slightly inferior to the through slot 1511 design in terms of flexibility in position adjustment, it has its unique advantages in terms of positioning accuracy and structural stability, because each locking point can be designed to be more solid and better able to withstand the weight of the second positioning rod 152 and the overcurrent pole 20, as well as various forces generated during the detection process.
[0058] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
[0059] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, various possible combinations are not described again in the present application.
