The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0042] A stacked battery cell pack consists of multiple stacked cells. When performing a high potential withstand test, each cell needs to be tested. In related technologies, the commonly used testing device separates the tabs of the cell to be tested from the tabs of the untested cells and tests the tabs of the cells one by one. However, since the battery contains multiple cells, this testing method and device are too inefficient.

[0043] In view of the above-mentioned testing situation, this application provides a testing assistance device to improve the testing situation.

[0044] Please see Figure 1 , Figure 1 This is a perspective view of a testing auxiliary device provided in an embodiment of this application (wherein, only one core package lamination is shown). The testing auxiliary device includes: an insulating base plate 1 having a first surface 11, the first surface 11 having a core package placement area and a peripheral area surrounding the core package placement area; a rotating shaft 2 protruding from the peripheral area; and a plurality of insulating sheets 3 rotatably mounted on the rotating shaft 2, the plurality of insulating sheets 3 being configured to separate the tabs 41 of the core package lamination 4 during testing.

[0045] In this embodiment, by mounting multiple insulating sheets 3 on the rotating shaft 2, the tabs 41 of multiple stacked laminations 4 in the core package can be separated at once using the multiple insulating sheets 3 during core package testing. Then, multiple testing devices can be used to simultaneously test the separated stacked laminations 4, which helps improve testing efficiency. Simultaneously, using multiple insulating sheets 3 to separate faulty stacked laminations 4 prevents them from affecting the test results of the stacked laminations 4 under test, thus helping to improve the accuracy of the test results.

[0046] It is understood that the stack 4 to be tested here can be a single stack 4 or a group of stack 4 (i.e., the number of stack 4 is greater than or equal to 2). This application does not limit the specific test method.

[0047] Furthermore, when using traditional testing auxiliary devices, if a faulty lamination 4 (i.e., a lamination 4 with a short circuit result) is found in the core package, an insulating sheet 3 is used to separate the faulty lamination 4 from the untested laminations 4 to prevent the faulty lamination 4 from affecting the testing of the untested laminations 4. However, since traditional testing auxiliary devices are usually only equipped with one insulating sheet 3 (used to separate the positive tab 411 and negative tab 412 of the lamination 4 to be tested from the untested laminations 4 or the faulty laminations 4), when there are multiple faulty laminations 4 in the core package, it is impossible to accurately find all the faulty laminations 4 through testing. For example, if the core package contains 50 laminations 4, and during testing, the laminations 4 are tested one by one, and when the 20th lamination 4 is found to be faulty, a single insulating sheet 3 is used to separate the faulty laminations 4 from the untested laminations 4. Insulating sheet 3 separates the 20th stack 4 from the 21st to 50th stacks 4, and then tests the 21st to 50th stacks 4. However, since the traditional test auxiliary device is only equipped with one insulating sheet 3, and this insulating sheet 3 is already used to separate the 20th stack 4 from the tabs 41 of the 21st to 50th stacks 4, it is not possible to test the 21st stack 4 and the 50th stack 4 one by one. The 21st to 50th stacks can only be tested as a whole. When the test results show that there is a faulty stack 4 among the 21st to 50th stacks, due to the lack of sufficient insulating sheets 3, it is not possible to further confirm the number of faulty stacks 4, nor can it further confirm the specific location of the faulty stack 4 among the 21st to 50th stacks 4. Therefore, the test results of the traditional test auxiliary device are inaccurate.

[0048] The testing auxiliary device provided in this application includes multiple insulating sheets 3. When encountering the above-mentioned testing situation, the insulating sheets 3 can be used to separate the tabs 41 of the 21st stacked lamination 4 from those of the 22nd stacked lamination 4, and then the 21st stacked lamination 4 can be tested. This process is repeated for each lamination until all stacked laminations 4 are tested, thus identifying all faulty stacked laminations 4. Alternatively, the insulating sheets 3 can be used to divide the 21st to 50th stacked laminations 4 into multiple groups, and each group can be tested. If a group has a faulty stacked lamination 4, the group is further subdivided, and the above testing method is continued until the faulty stacked laminations 4 are identified. In this way, not only can all faulty stacked laminations 4 be identified, improving the accuracy of the test results, but the number of tests can also be reduced to a certain extent, improving testing efficiency.

[0049] In some embodiments of this application, the insulating sheet 3 may be movable along the rotation axis 2, and / or the insulating sheet 3 may be detachably connected to the rotation axis 2.

[0050] The thickness of the laminations 4 may vary between different batteries. This application allows the insulating sheet 3 to move along the rotation axis 2, enabling flexible adjustment of the insulating sheet 3's position on the rotation axis 2 according to the different thicknesses and positions of the laminations 4. This allows the testing auxiliary device provided by this application to be applicable to batteries (cell packs) of more specifications and sizes. Moreover, by allowing the insulating sheet 3 to move along the rotation axis 2, it helps to meet the testing requirements of multi-laminated batteries with as few insulating sheets 3 as possible, that is, it helps to save the number of insulating sheets 3 while still meeting the testing requirements of multi-laminated batteries. Taking the example of testing a core pack containing 50 stacked wafers 4 as described earlier, after each stacked wafer 4 is tested, if the test result indicates that the currently tested stacked wafer 4 is fault-free, the position of the insulating sheet 3 on the rotating shaft 2 can be adjusted to achieve the effect of using the same insulating sheet 3 to separate different stacked wafers 4 in stages. When the test result indicates that the currently tested stacked wafer 4 is faulty, another insulating sheet 3 is used to separate the first stacked wafer 4 and the remaining stacked wafers 4 in the stacked wafers to be tested. In this way, the number of insulating sheets 3 can be reduced while still meeting the testing requirements of multi-stacked batteries.

[0051] Furthermore, by making the insulating sheet 3 detachably connected to the rotating shaft 2, the insulating sheet 3 can be added or removed during testing according to the specific number of stacked sheets 4 in the core pack, so that the testing auxiliary device provided in this application can be applied to batteries (core packs) of more specifications and sizes.

[0052] For example, the insulating sheet 3 has a first through hole, and a retaining ring is disposed within the first through hole. The retaining ring is made of elastic material, and its elasticity allows the insulating sheet 3 to be moved to a desired position on the rotating shaft 2 and then fixed in that position. Further, the rotating shaft 2 may be provided with a plurality of annular grooves extending circumferentially and spaced apart axially. The annular grooves are used to engage with the retaining ring to better secure the insulating sheet 3. When it is necessary to adjust the position of the insulating sheet 3 on the rotating shaft 2, the retaining ring can be disengaged from its currently engaged annular groove by utilizing its elasticity.

[0053] It is understood that the examples of the connection between the insulating sheet 3 and the rotating shaft 2 in the above embodiments are merely examples to facilitate understanding of this application, and this application does not limit the specific connection between the insulating sheet 3 and the rotating shaft 2.

[0054] In some embodiments of this application, a plurality of insulating sheets 3 are configured to separate the core package stack 4 to be tested and the untested stack 4 during testing, and / or to separate the core package stack 4 with a faulty core package and the stack 4 to be tested during testing.

[0055] If the stack 4 to be tested is not separated from the untested stack 4, it will be impossible to accurately determine the specific faulty stack 4 and its quantity when the test result indicates that a faulty stack 4 exists. Therefore, in this embodiment, when testing the stack 4 in the core package, an insulating sheet 3 is used to separate the stack 4 to be tested from the untested stack 4 so that the stack 4 to be tested can be tested directly based on the test result to determine whether the stack 4 to be tested is faulty. It should be noted that the stack 4 to be tested in this embodiment is a single stack 4. When the test result indicates that the stack 4 currently being tested is a faulty stack 4, in order to avoid the faulty stack 4 affecting the test result of the stack 4 to be tested, an insulating sheet 3 can be used to separate the stack 4 to be tested from the faulty stack 4.

[0056] Please continue reading. Figure 1 In some embodiments of this application, the test auxiliary device includes two rotating shafts 2, which are disposed on the same side of the insulating base plate 1, and each of the two rotating shafts 2 is fitted with an insulating sheet 3.

[0057] Using this scheme, the insulating sheets 3 on the two rotating shafts 2 can be used to separate the positive tab 411 and negative tab 412 of the stack 4 to be tested from the stack 4 not being tested and / or the stack 4 with a fault.

[0058] In some embodiments of this application, the testing auxiliary device may also include only a rotating shaft 2. In this case, the insulating sheet 3 sleeved on the rotating shaft 2 is used to simultaneously separate the positive tab 411 and negative tab 412 of the stack 4 to be tested from the stack 4 not tested and / or the stack 4 with a fault.

[0059] In one embodiment of the test auxiliary device including two rotating shafts 2, the insulating sheet 3 has a working state of separating tabs 41. When both insulating sheets 3 fitted on the two rotating shafts 2 are in working state, the insulating sheets 3 fitted on the two rotating shafts 2 are spaced apart.

[0060] To prevent misalignment of the laminates 4, adhesive tape is typically attached to the core package to bond the laminates 4 into a single unit. Adhesive tape is also usually placed on the core package structure between the positive and negative tab groups. To facilitate the placement of the insulating sheet 3 between the tabs of the laminate 4, this tape needs to be removed. In this embodiment, the insulating sheets 3 on the two rotating shafts 2 are spaced apart during operation, making it easier for operators to remove the tape from the core package, reducing the time required to move the core package and remove the tape, thereby improving testing efficiency. Furthermore, it also prevents damage to the core package during handling, such as bending of the tabs 41.

[0061] In addition, during testing, a short-circuit test is first performed on the fixture. If the test result indicates that the product is unqualified, the tape is then removed and the stack 4 is tested. This avoids damage to the core package caused by removing the tape before placing it on the fixture for testing, as well as over-killing and misjudgment during short-circuit disassembly.

[0062] Please see Figure 2 , Figure 2 This is a perspective view of another testing auxiliary device provided in some embodiments of this application. In some embodiments of this application, the insulating base plate 1 includes: an insulating substrate 12, the projection of the insulating substrate 12 in the first surface 11 is located in the core package placement area, and the area is smaller than the area of ​​the core package placement area; and a plurality of first insulating inserts 13, which are detachably connected to the periphery of the insulating substrate 12.

[0063] For example, the projection of the insulating substrate 12 into the first surface 11 is located within the core package placement area and is coaxially disposed with the core package placement area.

[0064] It is understood that the core package includes multiple stacked pieces 4. To prevent misalignment of the stacked pieces 4, tape or similar adhesive is usually glued around the core package to bond the stacked pieces 4 into a whole. During testing, the tape needs to be removed from the core package. In the testing auxiliary device provided in this application embodiment, the insulating base plate 1 supporting the core package includes an insulating substrate 12 and a first insulating insert 13 detachably connected to it. The projection of the insulating substrate 12 in the first surface 11 is located within the core package placement area, and its area is smaller than the area of ​​the core package placement area. This allows the first insulating insert 13 with adhesive tape to be removed during testing, so that the tape on the core package can be peeled off from the gap of the removed first insulating insert 13, avoiding damage to the core package when flipping or moving it to remove the tape.

[0065] Please continue reading. Figure 2 In some embodiments of this application, the insulating base plate 1 further includes a plurality of second insulating inserts 14, which are disposed at the four corners of the insulating substrate 12 and connected to the insulating substrate 12.

[0066] In one embodiment of this application, the second insulating insert 14 is detachably connected to the insulating substrate 12.

[0067] Please continue reading. Figure 2 In some embodiments of this application, the plurality of first insulating plates 13 are divided into four groups, and each group of first insulating plates 13 is disposed between two adjacent second insulating plates 14.

[0068] Please continue reading. Figure 2 In some embodiments of this application, each second insulating insert 14 is connected to the insulating substrate 12 via an adjacent first insulating insert 13.

[0069] Please continue reading. Figure 2 In some embodiments of this application, each group of first insulating inserts 13 is arranged end to end along one side of the insulating substrate 12, and the sum of the widths of the group of first insulating inserts 13 in the arrangement direction is equal to the length of the side.

[0070] This design allows for the provision of as many first insulating inserts 13 as possible on the side of the insulating substrate 12, enabling the auxiliary conveying device provided in this application to be applicable to more specifications and types of core packages.

[0071] Please continue reading. Figure 2 In some embodiments of this application, the insulating substrate 12, a plurality of first insulating inserts 13, and a plurality of second insulating inserts 14 are located in the same plane and together define the first surface 11. This prevents the core package from sliding during testing, improving testing safety, and also avoids damage to the core package caused by it slipping off the insulating base plate 1.

[0072] In some embodiments of this application, the second insulating insert 14 is provided with a mounting hole (not shown in the figure), and one end of the rotating shaft 2 is detachably connected to the mounting hole.

[0073] By adopting this approach, the position of the rotating shaft 2 can be flexibly selected according to testing requirements, making the testing auxiliary device provided in this application more widely applicable.

[0074] Please continue reading. Figure 2 In some embodiments of this application, it further includes: a fixing member 5 connected to the rotating shaft 2; a slide rail 141 is provided on the second insulating plate 14, and the rotating shaft 2 is configured to slide along the slide rail 141; the fixing member 5 is configured to fix the relative position between the rotating shaft 2 and the slide rail 141.

[0075] For core packages of different specifications and sizes, the distance between the tabs 41 and their edges may vary. In this embodiment, a slide rail 141 is provided on the second insulating insert plate 14, allowing the rotating shaft 2 to slide within the slide rail 141. This facilitates adjusting the position of the rotating shaft 2 according to the specific conditions of the core package being tested, ensuring that the insulating sheet 3 on the rotating shaft 2 can separate the tabs 41 of the laminated sheets 4 in the core package. When the rotating shaft 2 slides to a suitable position, it can be fixed by the fixing member 5 to prevent it from sliding during the test, which would affect the test results and test safety.

[0076] Please continue reading. Figure 2 In some embodiments of this application, the slide 141 includes a first sub-slide groove 141a and a second sub-slide groove 141b that are connected to each other; the first sub-slide groove 141a and the second sub-slide groove 141b are perpendicular to each other; the area enclosed by the first sub-slide groove 141a and the second sub-slide groove 141b faces the insulating substrate 12.

[0077] The positions of the tabs 41 in different core packages are different. In some core packages, the positive tab 411 and the negative tab 412 are located on the same side of the core package, while in some special core packages, the positive tab 411 and the negative tab 412 may be located on different sides of the core package. In this embodiment of the application, by making the slide 141 include a first sub-slide groove 141a and a second sub-slide groove 141b that are perpendicular to each other, the position of the rotating shaft 2 can be selected according to the actual situation during the test, so that the insulating sheet 3 sleeved on the rotating shaft 2 can separate the tabs 41 of the stacked sheets 4 in the core package and complete the test.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
