Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] The battery balancing device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, a battery balancing device includes: a fixed base 10, a telescopic assembly 20, a support arm 30 and a probe assembly 40; the battery balancing device has a first direction X and a second direction Y intersecting each other; the telescopic assembly 20 is mounted on the fixed base 10, and the support arm 30 is connected to the telescopic assembly 20. The telescopic assembly 20 can be telescopically moved along the second direction Y to adjust the position of the support arm 30; the probe assembly 40 is slidably connected to the support arm 30. The probe assembly 40 can move relative to the support arm 30 along the first direction X so that the probe assembly 40 contacts the battery 50 to balance the battery 50.

[0034] In an embodiment of the present application, the support arm 30 is connected to the telescopic assembly 20, and the probe assembly 40 is slidably connected to the support arm 30, so that the battery 50 can be placed under the support arm 30. By adjusting the telescopic movement of the telescopic assembly 20 and adjusting the sliding of the probe assembly 40 on the support arm 30, the probe assembly 40 can be precisely contacted with the electrodes of the battery 50 to perform a balancing operation on the battery 50. This facilitates precise adjustment of the relative position between the probe assembly 40 and the battery 50 to ensure stable contact between the probe assembly 40 and the battery 50, thereby improving the balancing quality of the battery 50 and improving the safety and reliability of the operation. In addition, the battery balancing device of the present application has a simple structure and is easy to operate.

[0035] It is understandable that in the field of battery manufacturing, multiple batteries 50 need to be connected in series or in parallel to form battery packs with different voltages and capacities. The differences in voltage and capacity of each battery 50 in the battery pack will affect the overall performance of the battery pack. For this reason, during the battery processing process, each battery 50 needs to be energy balanced to ensure that the performance of different batteries 50 is consistent.

[0036] In traditional battery balancing processes, manual balancing is typically performed. One end of a power cord is connected to a power source, and a clamp is provided at the other end of the power cord. During battery balancing, the clamp is manually held and clamped onto the positive and negative terminals of the battery 50. This method is not only inefficient but also prone to connection errors and loose clamps that can cause short circuits, posing safety hazards.

[0037] To this end, an embodiment of the present application provides a battery balancing device, in which a telescopic assembly 20 is mounted on a fixed base 10, a support arm 30 is connected to the telescopic assembly 20, and a probe assembly 40 is slidably connected to the support arm 30. Furthermore, when performing a balancing operation on a battery 50, the position of the probe assembly 40 along a first direction X can be adjusted by sliding the probe assembly 40, that is, the horizontal position of the probe assembly 40 can be adjusted so that the probe assembly 40 is positioned above the battery 50. Simultaneously, the position of the probe assembly 40 along a second direction Y can be adjusted by adjusting the telescopic state of the telescopic assembly 20, that is, the vertical position of the probe assembly 40 can be adjusted, so that the probe assembly 40 contacts the positive and negative electrodes of the battery 50.

[0038] The first direction X may be a horizontal direction, and the second direction Y may be a vertical direction.

[0039] In specific applications, the probe assembly 40 can be electrically connected to an external balancing power supply via a power cord, and then the balancing power supply energizes the battery 50 through the probe assembly 40 to perform battery balancing operations. This not only facilitates operation, but also ensures that the positive and negative poles of the probe assembly 40 and the battery 50 are accurately connected, which is safer, faster and more efficient.

[0040] Alternatively, as Figure 1 As shown, the telescopic assembly 20 includes a slide rail 21 and a telescopic sleeve 22; one end of the slide rail 21 is connected to the fixed base 10, and the other end of the slide rail 21 extends along the second direction Y toward the direction away from the fixed base 10, the telescopic sleeve 22 is slidably connected to the slide rail 21, and the support arm 30 is fixedly connected to the telescopic sleeve 22.

[0041] In an embodiment of the present application, the telescopic sleeve 22 is slidably connected to the slide rail 21, and the support arm 30 is fixedly connected to the telescopic sleeve 22. By moving the telescopic sleeve 22, the position of the support arm 30 along the second direction Y can be adjusted, and thus when performing battery balancing operations, the relative positions of the probe assembly 40 and the battery 50 along the second direction Y can be flexibly adjusted so that the electrodes of the probe assembly 40 and the battery 50 can be precisely contacted.

[0042] In some embodiments, the telescopic assembly 20 may include a slide rail and a slider. One end of the slide rail is connected to the fixed base 10, and the other end of the slide rail extends away from the fixed base 10 along the second direction Y. The slide rail is provided with a slide groove, and the slider is slidably connected to the slide groove. The support arm 30 is fixedly connected to the slider. The position of the probe assembly 40 on the support arm 30 along the second direction Y can be adjusted by moving the slider.

[0043] It should be noted that the telescopic component 20 may also use other adjustable structures, and those skilled in the art may flexibly select them according to actual conditions, and no limitation is made here.

[0044] Alternatively, as Figure 1 As shown, the telescopic assembly 20 further includes a first locking structure 23 . The first locking structure 23 is provided between the slide rail 21 and the telescopic sleeve 22 and is used to lock the relative positions of the slide rail 21 and the telescopic sleeve 22 .

[0045] In an embodiment of the present application, a first locking structure 23 is provided between the slide rail 21 and the telescopic sleeve 22 so that after the relative positions of the slide rail 21 and the telescopic sleeve 22 are adjusted, the positions of the slide rail 21 and the telescopic sleeve 22 are locked to prevent the telescopic sleeve 22 from moving during subsequent operations.

[0046] Alternatively, as Figure 1 and Figure 2As shown, the first locking structure 23 includes a tensioning bolt 231 . A threaded hole is provided in the telescopic sliding sleeve 22 . The tensioning bolt 231 passes through the threaded hole and abuts against the slide rail 21 . The tensioning bolt 231 is threadedly connected to the threaded hole.

[0047] In the embodiment of the present application, a locking structure is formed by threaded cooperation between the tensioning bolt 231 and the threaded hole in the telescopic sleeve 22. Then, by turning the tensioning bolt 231, the abutment force between the tensioning bolt 231 and the slide rail 21 can be adjusted, thereby achieving locking or unlocking between the telescopic sleeve 22 and the slide rail 21. The structure is simple and easy to operate.

[0048] Of course, the first locking structure 23 can also adopt a pin locking structure, a lock locking structure, etc. Those skilled in the art can flexibly select them according to actual needs, and this application does not limit them here.

[0049] Alternatively, as Figure 1 and Figure 2 As shown, there are at least two probe assemblies 40 , and the at least two probe assemblies 40 are respectively slidably connected to the support arm 30 .

[0050] In the embodiment of the present application, at least two probe assemblies 40 are provided on the support arm 30 to match the different electrodes of the battery 50. Furthermore, by slidably connecting the at least two probe assemblies 40 to the support arm 30, the position of each probe assembly 40 can be individually adjusted so that each probe assembly 40 can precisely connect with the electrode of the battery 50. Furthermore, the spacing between two adjacent probe assemblies 40 can be flexibly adjusted to match batteries 50 of different specifications, thereby improving the applicability of the battery balancing device.

[0051] For example, Figure 2 As shown, two probe assemblies 40 can be set on the support arm 30. When performing a battery balancing operation, one of the probe assemblies 40 can be adjusted to make contact with the positive electrode of the battery 50, and the other probe assembly 40 can be adjusted to make contact with the negative electrode of the battery 50. Thus, the balancing operation of the battery 50 is achieved through the two probe assemblies 40.

[0052] Furthermore, the number of probe assemblies 40 on the support arm 30 can be set to be greater than two, so that the battery balancing device of the present application can simultaneously perform balancing operations on multiple batteries 50, which can improve processing efficiency.

[0053] Alternatively, as Figure 1 and Figure 3 As shown, the probe assembly 40 includes a sliding member 41 and a probe 42 . The sliding member 41 is slidably connected to the support arm 30 along a first direction X, and the probe 42 is connected to the sliding member 41 .

[0054] In the embodiment of the present application, the sliding piece 41 is slidingly connected to the support arm 30, and the probe 42 is connected to the sliding piece 41. By sliding the sliding piece 41 on the support arm 30, the position of the probe 42 along the first direction X can be adjusted, so that the relative position between the probe 42 and the electrode of the battery 50 can be accurately adjusted during the battery equalization operation, and the probe 42 can be accurately connected to the electrode of the battery 50.

[0055] Optionally, as shown in Figure 4 and Figure 5 , the probe 42 comprises a probe body 421, an elastic piece 422 and a probe head 423. The probe body 421 is connected to the sliding piece 41, and the probe body 421 is provided with a mounting hole 4210. The elastic piece 422 is arranged in the mounting hole 4210, and the probe head 423 at least partially extends into the mounting hole 4210 and is connected to the elastic piece 422.

[0056] In the embodiment of the present application, the probe head 423 is elastically connected to the probe body 421 through the elastic piece 422. When the probe head 423 abuts against the electrode of the battery 50, the elastic piece 422 can be elastically deformed to provide a certain pre-tightening force for the probe head 423, so as to ensure that the probe head 423 always maintains close contact with the electrode of the battery 50 during the equalization operation, which helps to improve the equalization effect. In addition, by elastically connecting the probe head 423 to the probe body 421, the elastic piece 422 can also play a buffering role when the probe 42 is adjusted to contact the battery 50, so as to avoid rigid impact of the probe head 423 on the battery 50, and play a role in protecting the probe head 423 and the battery 50.

[0057] The elastic piece 422 can be selected from a metal spring, a rubber spring, a structural member made of an elastic material, etc., and can be flexibly set according to actual needs, which is not limited herein.

[0058] Optionally, as shown in Figure 4 and Figure 5 , the probe 42 further comprises an adjusting piece 424. The adjusting piece 424 is movably connected to the probe body 421, and a clamping space 401 is formed between the adjusting piece 424 and the probe body 421 for clamping and fixing a power line. The adjusting piece 424 can move relative to the probe body 421 to adjust the size of the clamping space 401.

[0059] In the embodiment of the present application, the adjusting member 424 is arranged on the probe body 421 to form the clamping space 401 between the adjusting member 424 and the probe body 421, and then the power cord can be clamped and fixed in the clamping space 401, so as to electrically connect the probe 42 and the external balancing power supply by the power cord. Meanwhile, the adjusting member 424 can also move relative to the probe body 421, so as to adjust the size of the clamping space 401 formed between the adjusting member 424 and the probe body 421, facilitating the fixing and dismounting of the power cord.

[0060] In a specific application, the adjusting member 424 can be a fixing bolt, the top end of the probe body 421 is provided with a threaded hole, the fixing bolt is threadedly connected with the threaded hole, and the clamping space 401 is formed between the fixing bolt and the end face of the probe body 421, so that one end of the power cord can be placed in the clamping space 401 when connected, and the power cord is clamped and fixed by tightening the fixing bolt.

[0061] Alternatively, as shown in Figure 3 The probe assembly 40 further comprises a second locking structure 43 arranged between the sliding member 41 and the support arm 30, for locking the relative position of the sliding member 41 and the support arm 30.

[0062] In the embodiment of the present application, the second locking structure 43 is arranged between the sliding member 41 and the support arm 30, so that after the relative position of the sliding member 41 and the support arm 30 is adjusted, the position of the sliding member 41 and the support arm 30 is locked by the second locking structure 43, avoiding the movement of the position of the probe assembly 40 during the balancing operation, thereby affecting the balancing effect of the battery.

[0063] In some embodiments, the second locking structure 43 can comprise a bolt and a threaded hole arranged in the support arm 30, so that the bolt is threadedly connected with the threaded hole in the support arm 30 through the sliding member 41, and then the sliding member 41 and the support arm 30 are locked or unlocked by screwing the tightening bolt 231.

[0064] Of course, the second locking structure 43 can also be other locking structures, which can be selected flexibly by those skilled in the art according to actual needs, and the present application does not make any limitation here.

[0065] In some embodiments, as shown in Figure 1 The support arm 30 is an insulating rod. By arranging the support arm 30 as an insulating rod, the support arm 30 has insulation performance, thereby improving the safety performance of the battery balancing device.

[0066] In other embodiments, as shown in Figure 1As shown, the slider 41 is an insulating slider. By setting the slider 41 as an insulating slider, the slider 41 can slide along the support arm 30 while having insulating properties, thereby providing insulation between the probe assembly 40 and the support arm 30, thereby improving the safety performance of the battery balancing device.

[0067] Exemplarily, the support arm 30 or the sliding part 41 can be made of insulating materials such as insulating plastic, insulating rubber, and insulating composite materials. The support arm 30 and the sliding part 41 can be made of the same material or different materials. Those skilled in the art can flexibly select the materials of the support arm 30 and the sliding part 41 according to actual needs, and this application does not limit this.
