The soft-pack battery is a kind of power battery, which has the characteristics of light weight, high energy density, good safety and flexible design, and has broad development prospects.
[0003] In the development stage of soft-pack batteries, it is necessary to characterize their electrical properties through electrical performance tests. The battery fixture is an indispensable auxiliary tool during the test. On the one hand, it can apply a certain pressure to the battery to simulate the actual stress state of the battery in the module, so that the obtained data is more real. On the other hand, it can restrain the battery to prevent harm to personnel and equipment when the battery has a thermal failure.
[0004] When performing electrical performance tests on soft-pack batteries, the tabs of the soft-pack batteries are usually connected to the wire harnesses of the charge and discharge equipment. Since the tabs are relatively thin, the connection between the wire harnesses and the tabs often breaks during the test, resulting in the interruption of the test. If a strong connection is established between the tabs and the wire harnesses, the tabs are likely to fall off. Therefore, the current battery fixtures are not convenient for performing electrical performance tests on batteries. Summary of the Utility Model

[0022] The beneficial effects of the present utility model are as follows:

Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.
[0035] Currently, when performing electrical performance tests on soft-pack batteries, the following two methods are mainly used to connect the wire harness of the charge and discharge device and the tabs of the soft-pack battery:
[0036] The first method is to use alligator clips to clamp the battery tabs. Considering that the tab thickness is relatively thin and the clamping force of the alligator clips is small, there is a risk of detachment and disconnection during the test process.
[0037] The second connection method is to first punch holes in the tabs of the soft-pack battery, pass bolts through the tab holes and the copper bar holes of the charge and discharge wire harness, and then clamp with nuts to complete the connection. The defect of this connection method is that the wire harness of the charge and discharge device is prone to pulling on the tabs of the soft-pack battery, and the battery tabs are the most vulnerable part of the soft-pack battery. There is a problem of tab detachment during connection, disassembly, and testing, resulting in electrolyte leakage of the battery cell, which not only brings great risks to the test, but also requires returning to the factory for re-welding the tabs, prolonging the test time.
[0038] To sum up, the defects and deficiencies of using conventional fixtures for electrical performance testing of soft-pack batteries are as follows:
[0039] 1. It is impossible to ensure a stable connection between the wire harness of the charge and discharge device and the tabs of the soft-pack battery, and there is a risk of interrupting the test.
[0040] 2. It is impossible to ensure that the tabs of the soft-pack battery are not pulled by the wire harness of the charge and discharge device, and there is a risk of tab detachment and electrolyte leakage in the soft-pack battery.
[0041] 3. When punching holes in the tabs of the soft-pack battery, the structure of the battery tabs is damaged, and at the same time, the working process of fixture installation is also increased.
[0042] In view of the above defects and deficiencies, the inventor of the present invention has proposed a battery fixture, which is expected to improve the above defects and deficiencies. Please refer toFigures 1 to 4 , Figure 1 is a schematic assembly structure diagram of a battery fixture provided by an embodiment of the present utility model, Figure 2 and Figure 1 is a schematic exploded structure diagram of the battery fixture in Figure 3 ; Figure 1 is a schematic cross-sectional structure diagram of the battery fixture 100 in Figure 4 ; Figure 3 is a schematic enlarged structure diagram of the area A in . An embodiment of the present utility model provides a battery fixture 100. The battery fixture 100 includes a lower clamping seat 10, a conductive member 20, an upper clamping seat 30, and an adjusting assembly 40. The upper clamping seat 30 is connected to the lower clamping seat 10, and the upper clamping seat 30 and the lower clamping seat 10 are used to jointly clamp the battery 200; the adjusting assembly 40 is connected to the upper clamping seat 30 and extends between the upper clamping seat 30 and the lower clamping seat 10, and the conductive member 20 is disposed on any one or both of the lower clamping seat 10 and the adjusting assembly 40; the adjusting assembly 40 is used to elastically abut the tab 210 of the battery 200 against the conductive member 20.
[0043] Specifically, the battery 200 includes a battery body 220 and positive and negative electrode tabs 210 connected to the battery body 220. The battery body 220 is clamped between an upper clamping seat 30 and a lower clamping seat 10. The upper clamping seat 30 and the lower clamping seat 10 act to restrain the battery 200 and hold it fixed. The conductive member 20 is disposed on either or both of the lower clamping seat 10 and the adjusting assembly 40. The adjusting assembly 40 elastically abuts the positive and negative electrode tabs 210 of the battery 200 against the conductive member 20 so that the positive and negative electrode tabs 210 of the battery 200 are tightly connected to the conductive member 20. When it is necessary to perform an electrical performance test on the battery 200, the wire harness of the charge and discharge device can be connected to the conductive member 20, then the battery body 220 is placed on the lower clamping seat 10, and the positive and negative electrode tabs 210 are placed at positions corresponding to the lower clamping seat 10 and the conductive member 20. Then, the upper clamping seat 30 is placed on the lower clamping seat 10, and after connecting the upper clamping seat 30 and the lower clamping seat 10, the electrical performance test of the battery 200 can be started. In the embodiment of the present utility model, by providing the adjusting assembly 40 that elastically abuts the electrode tabs 210 of the battery 200 against the conductive member 20 and connecting the conductive member 20 to the charge and discharge device, since the positive and negative electrode tabs 210 of the battery 200 are not directly connected to the charge and discharge device, the electrical connection between the positive and negative electrode tabs 210 and the charge and discharge device is stable, not easily causing a test interruption, and not causing the positive and negative electrode tabs 210 of the battery 200 to be pulled off by the charge and discharge wire harness. Moreover, the structure of the electrode tabs 210 is complete, and the installation of the battery fixture 100 is relatively convenient, thereby improving the test efficiency and test stability. In addition, the battery fixture 100 in the embodiment of the present utility model can be applicable to batteries 200 of various sizes, electrode tabs 210 of various sizes, and electrode tabs 210 with various spacings, and has strong applicability.
[0044] Among them, the conductive member 20 can be made of a metal material with good electrical conductivity. For example, it can be made of a copper sheet to improve the electrical conductivity between the positive and negative electrode tabs 210 and the conductive member 20. And since the copper sheet is in a thin sheet shape, the conductive member 20 and the positive and negative electrode tabs 210 of the battery 200 are in surface contact, avoiding the conductive member 20 from damaging the positive and negative electrode tabs 210 of the battery 200.
[0045] In an alternative embodiment, the conductive member 20 can be disposed on the lower clamping seat 10, that is, at a position corresponding to the lower clamping seat 10 and the adjusting assembly 40. During the test, the positive and negative electrode tabs 210 of the battery 200 can be placed on the conductive member 20 so that the lower surface of the positive and negative electrode tabs 210 is in contact electrical connection with the conductive member 20.
[0046] Alternatively, the conductive member 20 can be disposed on the adjusting assembly 40, that is, the conductive member 20 is disposed at a position where the adjusting assembly 40 contacts the positive and negative electrode tabs 210 of the battery 200. Thus, during the electrical performance test, when the adjusting assembly 40 abuts against the electrode tab 210, the conductive member 20 can be in electrical connection by contacting the upper surface of the electrode tab 210.
[0047] Alternatively, the conductive member 20 can also be disposed on both the lower clamping seat 10 and the adjusting assembly 40, that is, the conductive member 20 can be disposed at a position corresponding to the electrode tab 210 on the lower clamping seat 10 and at a position where the adjusting assembly 40 contacts the positive and negative electrode tabs 210 of the battery 200. Thus, during the electrical performance test, both the upper and lower surfaces of the positive and negative electrode tabs 210 are in electrical connection by contacting the conductive member 20, so that the connection between the conductive member 20 and the positive and negative electrode tabs 210 is more stable.
[0048] Further, as Figure 3 、 Figure 4 and Figure 5 shown, Figure 5 is Figure 2 a schematic exploded view of the adjusting assembly 40 in
[0049] . The adjusting assembly 40 includes an adjusting rod 41, an elastic member 42, and a pressing plate 43. The adjusting rod 41 slidably penetrates through the upper clamping seat 30 along the clamping direction. Opposite ends of the adjusting rod 41 are respectively located on opposite sides of the upper clamping seat 30. The pressing plate 43 is connected to one end of the adjusting rod 41 close to the lower clamping seat 10. The elastic member 42 is sleeved outside the adjusting rod 41 and is located between the pressing plate 43 and the upper clamping seat 30. The elastic member 42 is used to provide an elastic force for the pressing plate 43 so that the pressing plate 43 elastically abuts against the electrode tab 210 of the battery 200.
[0050] Further, as Figure 5 shown, in this embodiment, the elastic member 42 is a spring, and the elastic member 42 surrounds the outer periphery of the adjusting rod 41. Using a spring as the elastic member 42 not only facilitates replacement when the spring is damaged, but also enables the abutting force of the elastic member 42 on the pressing plate 43 to be more uniform.
[0051] Optionally, in some other embodiments, the elastic member 42 can also be made of elastic materials such as metal shrapnel and elastic foam.
[0052] Further, as shown in Figure 4 and Figure 5 , the adjusting assembly 40 further includes a limiting member 44. The limiting member 44 is connected to one end of the adjusting rod 41 away from the pressing plate 43, and the limiting member 44 is used to hold the adjusting rod 41 on the upper clamping seat 30.
[0053] Specifically, the cross-sectional dimension of the limiting member 44 is larger than the dimension of the through hole 31. The limiting member 44 is arranged on the side of the upper clamping seat 30 facing away from the lower clamping seat 10 and connected to the adjusting rod 41, so that the adjusting rod 41 can be held on the upper clamping seat 30, restricting the adjusting rod 41 from moving towards the lower clamping seat 10, but not restricting the movement of the pressing plate 43 towards the upper clamping seat 30. Therefore, when the thickness of the tab 210 of the battery 200 is relatively large, it can promote the pressing plate 43 to move towards the upper clamping seat 30. The setting of the limiting member 44 can hold the adjusting assembly 40 on the upper clamping seat 30, avoiding frequent assembly of the adjusting assembly 40 during the test.
[0054] Further, in order to simplify the structure of the limiting member 44, the limiting member 44 can be set as a structure integral with the adjusting rod 41. As shown in Figure 4 and Figure 5 , the limiting member 44 can be set as a protrusion extending from the outer surface of the adjusting rod 41 in a direction away from the central axis of the adjusting rod 41.
[0055] In this embodiment, the protrusion is a continuous annular protrusion, and the outer cross-sectional dimension of the annular protrusion is larger than the dimension of the through hole 31. Alternatively, optionally, the protrusion can also be a plurality of protrusions arranged at intervals around the outer circumference of the adjusting rod 41, and the plurality of protrusions are simultaneously supported on the upper clamping seat 30, thereby limiting the adjusting rod 41.
[0056] Optionally, in some other embodiments, the limiting member 44 can also be an element separate from the adjusting rod 41. For example, the limiting member 44 can be a nut, and a thread can be provided on the adjusting rod 41 to thread-connect the limiting member 44 and the adjusting rod 41. Alternatively, the limiting member 44 can also be a ring provided with a buckle, and a slot can be provided on the adjusting rod 41 to connect the limiting member 44 and the adjusting rod 41 by snap-fastening through the buckle and the slot.
[0057] Further, in order to reduce the weight of the battery fixture 100 and facilitate the replacement of different tabs 210 for testing, the weight of the upper clamping seat 30 can be set to be relatively light. However, the relatively light weight of the upper clamping seat 30 will inevitably result in a smaller thickness of the upper clamping seat 30 and a shorter axial distance of the through hole 31. When the adjusting rod 41 moves along the axial direction of the through hole 31, the adjusting rod 41 may be skewed, which may affect the movement deviation of the pressing plate 43.
[0058] Therefore, in this embodiment, as shown inFigures 3 to 5 As shown, it can be set that the adjusting assembly 40 further includes a guiding member 45, and the guiding member 45 is arranged between the limiting member 44 and the upper clamping seat 30, and the guiding member 45 is sleeved on the adjusting rod 41.
[0059] Specifically, the guiding member 45 is a cylinder extending along the axial direction of the adjusting rod 41. By sleeving the guiding member 45 around the adjusting rod 41, the guiding effect of the through hole 31 on the adjusting rod 41 can be extended, preventing the adjusting rod 41 from skewing in the through hole 31, making the movement of the adjusting rod 41 more precise and avoiding the offset of the pressing plate 43.
[0060] Furthermore, in order to facilitate the connection of the conductive member 20 to the wiring harness of the charging and discharging device, the conductive member 20 can be extended and arranged outside the lower clamping seat 10 and the upper clamping seat 30. Specifically, as Figure 1 and Figure 2 shown, the battery fixture 100 includes a boss 60, and the boss 60 is connected to the side of the lower clamping seat 10, and the conductive member 20 is extended and arranged on the boss 60.
[0061] Specifically, the upper surface of the boss 60 and the upper surface of the lower clamping seat 10 are in the same plane. Part of the conductive member 20 is arranged on the upper surface of the lower clamping seat 10, and part is extended and arranged on the upper surface of the boss 60. Since the boss 60 is not covered by the upper clamping seat 30 and is exposed outside the lower clamping seat 10, by arranging the conductive member 20 on the boss 60, it is convenient to connect to the wiring harness of the charging and discharging device and avoid the wiring harness of the charging and discharging device from contacting the ear 210 of the battery 200.
[0062] Optionally, the boss 60 and the lower clamping seat 10 can be an integral structure to simplify the structure of the battery fixture 100 and improve the detection efficiency. Or, the boss 60 can also be connected to the lower clamping seat 10 by fasteners, and no specific limitation is made here.
[0063] Furthermore, as Figure 2 and Figure 3 shown, the upper clamping seat 30 includes a first part 32 and a second part 34 that are connected to each other. The first part 32 and the lower clamping seat 10 are used to jointly clamp the battery 200. A working cavity 33 is formed at an interval between the second part 34 and the lower clamping seat 10. The conductive member 20 is assembled in the working cavity 33, and the ear 210 of the battery 200 is accommodated in the working cavity 33.
[0064] Specifically, the upper clamping seat 30 includes a first part 32 arranged in parallel and spaced apart from the lower clamping seat 10, and a second part 34 bent and connected to the first part 32. The second part 34 is bent away from the lower clamping seat 10 to form a working cavity 33 at an interval from the lower clamping seat 10. The conductive member 20 is disposed on the surface of the lower clamping seat 10 within the working cavity 33. The adjusting assembly 40 is connected to the second part 34. At this time, the pressing plate 43 and the limiting member 44 are located within the working cavity 33 and are used to abut against the electrode tab 210 of the battery 200 located within the working cavity 33. The battery body 220 is clamped between the first part 32 and the lower clamping seat 10 and is fixed by the clamping force of the first part 32 and the lower clamping seat 10.
[0065] Further, as Figure 1 and Figure 6 shown, Figure 6 is Figure 1 a schematic cross-sectional view of the battery fixture 100 in another cross-section. The battery fixture 100 includes a plurality of connecting components 50, and the plurality of connecting components 50 are respectively connected to the upper clamping seat 30 and the lower clamping seat 10. The plurality of connecting components 50 are used to hold the battery 200 fixed between the upper clamping seat 30 and the lower clamping seat 10, facilitating subsequent electrical performance testing of the battery 200.
[0066] Specifically, in this embodiment, the number of the connecting components 50 is four, and the four connecting components 50 are arranged at intervals in pairs on the periphery of the upper clamping seat 30 and the lower clamping seat 10, so that the connection between the upper clamping seat 30 and the lower clamping seat 10 is more stable, and the pressing force on the battery 200 is more uniform.
[0067] Further, some of the connecting components 50 in this embodiment are arranged at positions of the upper clamping seat 30 and the lower clamping seat 10 close to the working cavity 33, so as to prevent the battery body 220 from shaking relative to the electrode tab 210 of the battery 200, thereby causing damage to the electrode tab 210 due to force pulling.
[0068] In a specific embodiment, as Figure 6 shown, the connecting component 50 may include a screw 51 and a nut 52. The screw 51 passes through the upper clamping seat 30 and the lower clamping seat 10 in sequence, and the nut 52 is threadedly connected to the screw 51 to tightly connect the upper clamping seat 30 and the lower clamping seat 10.
[0069] Specifically, assembly holes 53 are respectively provided on the upper clamping seat 30 and the lower clamping seat 10. After the screw 51 passes through the assembly holes 53 on the upper clamping seat 30 and the lower clamping seat 10, it is connected to the nut 52. By setting the conventional screw 51 and nut 52 as the connecting structure, the structural complexity of the components can be reduced, and the production cost brought by using more non-standard components can be avoided.
[0070] Based on the above battery fixture 100, on the other hand, the present utility model also provides a battery testing device 00, as Figure 7 shown, Figure 7 which is a schematic structural diagram of the battery testing device 00 in another embodiment of the present utility model. The battery testing device 00 includes a charge and discharge device 01 and a battery fixture 100, and the charge and discharge device 01 is electrically connected to the conductive member 20 of the battery fixture 100.
[0071] Specifically, the charge and discharge device 01 can adopt an existing charge and discharge device 01 for battery electrical performance testing. By directly connecting the wire harness of the charge and discharge device 01 to the conductive member 20, the conductive connection between the charge and discharge device 01 and the ear 210 of the battery 200 can be achieved, so as to facilitate the electrical performance testing of the battery 200.
[0072] Compared with the prior art, in the embodiment of the present utility model, by providing an adjusting component 40 that elastically holds the ear 210 of the battery 200 against the conductive member 20 and connecting the conductive member 20 to the charge and discharge device, since the positive and negative ears 210 of the battery 200 are elastically held against the conductive member 20 by the adjusting component 40, and the positive and negative ears 210 of the battery 200 are not directly connected to the charge and discharge device, therefore, the electrical connection between the positive and negative ears 210 and the charge and discharge device is stable, which is not likely to cause a test interruption, nor will it cause the positive and negative ears 210 of the battery 200 to fall off due to being pulled by the charge and discharge wire harness. Moreover, the structure of the ear 210 is complete, and the installation of the battery fixture 100 is relatively convenient, thereby improving the test efficiency and test stability. In addition, the battery fixture 100 in the embodiment of the present utility model can be applicable to batteries 200 of various sizes, ears 210 of various sizes, and ears 210 with various spacings, and has strong applicability.
[0073] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indication will also change accordingly.
[0074] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or can also be indirectly connected to the other element through an intermediate element.
[0075] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0076] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
