The battery pack testing device is used to test battery packs on a flow production line. Specifically, the battery pack testing device may include: a housing 10, a driving mechanism, and a plugging mechanism. The driving mechanism and the plugging mechanism are both disposed inside the housing 10.

[0039] The housing 10 is used to cover the battery pack.

[0040] The driving mechanism is movably connected to the housing 10.

[0041] The plugging mechanism is movably connected to the driving mechanism.

[0042] When the flow production line conveys the battery pack into the housing 10, the housing 10 covers the outer periphery of the battery pack, and the driving mechanism drives the plugging mechanism to plug into the battery pack, so as to test the battery pack through the plugging mechanism.

[0043] In the embodiment of the present application, when testing the battery pack, the housing 10 can be covered on the outer periphery of the battery pack to prevent other external structures from affecting the structure of the battery pack and the testing process of the battery pack, playing a protective role for the battery pack. Then, by the movement of the driving mechanism relative to the housing 10, the relative position between the driving mechanism and the battery pack is adjusted, so that the plugging mechanism connected to the driving mechanism and the battery pack can be relatively arranged. Furthermore, the driving mechanism drives the plugging mechanism to move towards the battery pack, so that the plugging mechanism can be accurately plugged into the battery pack, and performance tests such as the communication function or electrical function of the battery pack are carried out, improving the testing stability. Specifically, the battery pack testing device can be arranged on the flow production line of the battery pack. The housing 10 covers the outer periphery of the battery pack to be tested, eliminating the need for manual placement of the battery pack on the battery pack testing device, improving production efficiency, and avoiding moving the battery pack, thereby avoiding frictional damage to the battery pack and improving the yield rate of the battery pack.

[0044] Specifically, in the embodiments of the present application, the battery pack testing device can be used to perform EOL offline testing on the battery pack, including battery charge and discharge testing, battery safety regulations detection, battery parameter testing, auxiliary function testing, etc., so that the battery pack has better performance after offline, improving the yield rate of the product. After completing the EOL test on the battery pack, the driving mechanism can drive the plugging mechanism to move away from the battery pack, disconnect the connection between the plugging mechanism and the battery pack, and the driving mechanism moves upward relative to the housing 10 to return to the initial position, facilitating the movement of the speed chain on the flow production line to convey the tested battery pack to the next station, enabling the next battery pack to be tested to be located within the housing 10 of the battery pack testing device, and realizing the sequential testing of multiple battery packs on the flow production line, improving production efficiency.

[0045] Exemplarily, in the embodiments of the present application, a speed chain is provided on the battery pack flow production line. The speed chain can be provided with a tooling plate, and the battery pack is connected to the tooling plate, so that the battery pack has better stability during the testing process and during the movement along with the speed chain, reducing the risk of the battery pack being unstable and prone to shaking. In some optional embodiments of the present application, a lifting mechanism can also be provided on the battery pack flow production line. The tooling plate is connected to the lifting mechanism, and the lifting mechanism is used to lift the tooling plate so that the battery pack is lifted to a preset height. After completing the EOL test on the battery pack, the lifting mechanism can descend to the initial position, enabling the battery pack to return to the initial position for conveying it to the next station. A positioning structure can also be provided on the lifting mechanism to position the position of the tooling plate through the positioning structure, thereby achieving a relatively accurate positioning effect on the battery pack on the tooling plate and avoiding damage to the external structure of the battery pack.

The control panel is electrically connected to the driving mechanism and the plugging mechanism. In this way, motion parameters and the like can be set through the control panel to control the driving mechanism to perform relatively precise motion, and to control the plugging mechanism to be plugged into the battery pack more precisely. For example, a control switch may be provided on the control panel to control the start or stop of the motion of the driving mechanism and the plugging mechanism through the control switch, thereby improving the test accuracy of the battery pack testing device.

[0049] Optionally, in the embodiments of the present application, the driving mechanism includes a first driving member 20 and a second driving member 30; the first driving member 20 is movably connected to the housing 10 in the vertical direction, the second driving member 30 is connected to the first driving member 20, and the plugging mechanism is movably connected to the second driving member 30 in the horizontal direction; the first driving member 20 drives the second driving member 30 to move in the vertical direction, and the second driving member 30 drives the plugging mechanism to be plugged into the battery pack in the horizontal direction. In this way, the driving structure is movably connected to the housing 10 through the first driving member 20, and the driving mechanism drives the plugging mechanism through the second driving member 30.

[0050] Specifically, in the embodiments of the present application, the first driving member 20 drives the second driving member 30 to move in the vertical direction, so that the plugging mechanism connected to the second driving member 30 moves in the vertical direction, realizing the lifting function of the plugging structure connected to the second driving member 30, that is, adjusting the relative position between the plugging mechanism and the battery pack in the vertical direction, so that the plugging position of the plugging mechanism and the battery pack is at the same height in the vertical direction. Then, the second driving member 30 drives the plugging mechanism to move in the horizontal direction, so that the plugging mechanism is plugged into the plugging position of the battery pack, and the plugging mechanism is electrically connected to the battery pack, realizing the EOL offline test of the battery pack.

[0051] In the embodiments of the present application, for example, the specific value of the first driving member 20 driving the second driving member 30 to move in the vertical direction can be set according to the placement position of the battery pack and the specific size of the battery pack, etc. The embodiments of the present application may not limit this. Also, the specific value of the second driving member 30 driving the plugging mechanism to move in the horizontal direction can also be set according to the placement position of the battery pack and the specific size of the battery pack, etc. The embodiments of the present application may not limit this either.

[0052] Exemplarily, in the embodiments of the present application, the first driving member 20 may be a first cylinder, and the first cylinder may move in the vertical direction. The first cylinder provides a relatively stable and reliable driving force for the movement of the first driving member 20 in the vertical direction. In addition, the first driving member 20 may also be a first electric cylinder, etc. The embodiments of the present application may not limit the specific type of the first driving member 20. The second driving member 30 may be a second cylinder, and the second cylinder may move in the horizontal direction. The second cylinder provides a relatively stable and reliable driving force for the movement of the second driving member 30 in the horizontal direction. In addition, the second driving member 30 may also be a second electric cylinder, etc. The embodiments of the present application may not limit the specific type of the second driving member 30 either.

[0053] In the embodiments of the present application, optionally, the first driving member 20 includes a fixed portion 21 and a movable portion 22 movably connected to the fixed portion 21. A fixed plate 11 and a movable plate 12 are spaced apart in the housing 10; the fixed portion 21 is connected to the fixed plate 11, the movable portion 22 is connected to the movable plate 12, and the second driving member 30 is connected to the side of the movable plate 12 away from the movable portion 22; the fixed portion 21 drives the movable portion 22 to move in the vertical direction, and the movable portion 22 drives the movable plate 12 and the second driving member 30 to move in the vertical direction. In this way, a relatively firm connection between the first driving member 20 and the fixed plate 11 of the housing 10 is achieved through the fixed portion 21, so that the driving mechanism has better stability, and the movement of the first driving member 20 in the vertical direction is achieved through the movable portion 22. Moreover, the movable portion 22 of the first driving member 20 and the second driving member 30 are connected to both sides of the movable plate 12. Through the movable plate 12, the connection area between the movable portion 22 and the second driving member 30 is increased, and the connection firmness is improved, so that the movement of the movable portion 22 drives the movable plate 12 to move, and then the movable plate 12 drives the second driving member 30 to move in the vertical direction, so that the movable portion 22 and the second driving member 30 have a relatively stable and reliable connection, that is, a relatively stable and reliable setting basis is provided for the movable portion 22 and the second driving member 30 through the movable plate 12.

[0054] Optionally, in the embodiments of the present application, the battery pack testing device further includes a guiding member extending in the vertical direction. The guiding member is connected to the movable plate 12 and passes through the fixed plate 11, and the guiding member is slidably connected to the fixed plate 11; the movable plate 12 drives the guiding member to move, and the guiding member slides relative to the fixed plate 11 in the vertical direction. In this way, during the process of the movable portion 22 of the first driving member 20 driving the movable plate 12 to move, the movable plate 12 drives the guiding member to slide relative to the fixed plate 11 in the vertical direction, so that the movable plate 12 drives the second driving member 30 to maintain a movement in the vertical direction relative to the fixed plate 11, avoiding the problem that the movement of the movable portion 22 driving the second driving member 30 causes deviation and misalignment between the plugging mechanism and the battery pack.

[0055] In an embodiment of the present application, optionally, the guiding member includes a first guiding post 13 and a second guiding post 14 which are spaced apart. The first guiding post 13 and the second guiding post 14 extend in the vertical direction. The first guiding post 13 is connected to the movable plate 12 and penetrates through one end of the fixed plate 11, and the second guiding post 14 is connected to the movable plate 12 and penetrates through the other end of the fixed plate 11. In this way, through the first guiding post 13 located at one end of the fixed plate 11 and the second guiding post 14 located at the other end of the fixed plate 11, the guiding member acts on both ends of the fixed plate 11 simultaneously, so that the first guiding post 13 and the second guiding post 14 have good guiding stability for the movement of the movable plate 12 and the second driving member 30 in the vertical direction, avoiding the deflection of a single guiding post which may affect the guiding effect of the guiding member on the movable plate 12 and the second driving member 30 in the vertical direction. For example, the first guiding post 13 and the second guiding post 14 can be symmetrically distributed relative to the central axis of the fixed plate 11, further improving the guiding stability of the first guiding post 13 and the second guiding post 14 for the movable plate 12 and the second driving member 30.

A second opening is provided at the other end of the fixed plate 11, and the second guiding post 14 penetrates through and is slidably connected to the second opening.

In this way, the connecting plate 15 limits the movement of the first guiding post 13 and the second guiding post 14 in the vertical direction, avoiding the first guiding post 13 and the second guiding post 14 from disengaging from the fixed plate 11 when sliding in the vertical direction. Moreover, through the connecting plate 15, the relative positions between the first guiding post 13 and the second guiding post 14 are relatively stable, further improving the guiding stability of the guiding member.

[0058] In an embodiment of the present application, optionally, the battery pack testing device further includes a grounding member 40, and the grounding member 40 is connected to the movable plate 12. The grounding member 40 is used to abut against the battery pack to ground the battery pack. In this way, during the process of performing an EOL test on the battery pack, since it is necessary to energize the battery pack for testing the electrical performance of the battery pack, the grounding member 40 abuts against the battery pack to ground the battery pack, avoiding the end potential of the battery pack deviating from the zero potential point due to the battery pack not being grounded, and avoiding affecting the performance of the battery pack.

[0059] Exemplarily, in the embodiments of the present application, the grounding member 40 can be abutted against the tooling plate of the battery pack to achieve the grounding function of the battery pack. Exemplarily, the grounding member 40 can be a grounding post made of a metal material, such as a copper post or a steel post, etc. The embodiments of the present application can not limit the specific type and material of the grounding member 40.

[0060] Optionally, in the embodiments of the present application, the movable plate 12 is provided with a weight-reducing hole 121. In this way, on the basis of enabling the movable plate 12 to have good structural strength, the weight of the movable plate 12 is reduced through the weight-reducing hole 121, the driving force required for the fixing part 21 to drive the movable part 22 to drive the movable plate 12 to move is reduced, the energy consumption is reduced, which is beneficial to energy conservation and emission reduction, and is also beneficial to the lightweight design of the product.

[0061] Exemplarily, in the embodiments of the present application, as Figure 2 shown in the number of the weight-reducing holes 121 is 2, and the 2 weight-reducing holes 121 are symmetrically distributed relative to the central axis of the movable plate 12. In this way, the weight distribution of the movable plate 12 is relatively uniform, and it has good structural stability. In addition, the number of the weight-reducing holes 121 can also be 1 or 3, 4, etc. The embodiments of the present application can not limit the specific number of the weight-reducing holes 121. The shape of the weight-reducing hole 121 can be oval, circular or rectangular, etc. The embodiments of the present application can not limit the specific shape of the weight-reducing hole 121 either.

The connecting part 51 is slidably connected to the second driving member 30; the battery pack is provided with a plugging part. The second driving member 30 drives the connecting part 51 to move in the horizontal direction, and the connecting part 51 drives the plugging port 52 to move towards the plugging part, so that the plugging port 52 is plugged into the plugging part. In this way, the second driving member 30 is driven to drive the plugging mechanism to move in the horizontal direction through the connecting part 51. The movement of the connecting part 51 drives the plugging port 52 to be plugged into the plugging part of the battery pack, so as to realize the EOL test function of the battery pack through the plugging port 52. Exemplarily, the number of the plugging ports 52 can be 2, 3 or 4, etc. The embodiments of the present application can not limit the specific number and specific type of the plugging ports 52.

[0063] Exemplarily, in the embodiment of the present application, the insertion interface 52 includes at least one of a communication insertion interface 52 and a test insertion interface 52. Exemplarily, the communication insertion interface 52 and the test insertion interface 52 may be spaced apart. In this way, the communication function test of the battery pack is realized through the communication insertion interface 52, and the test of the electrical performance of the battery pack, etc. is realized through the test insertion interface 52. Exemplarily, the number of communication insertion interfaces 52 may be 1, 2, 3, etc., and can be set according to actual needs.
