Description

Technical Field

[0001] This utility model belongs to the field of devices for maintaining or repairing batteries, and in particular relates to a battery balancing device and battery balancing equipment. Background Technology

[0002] When battery modules or battery packs are stored for extended periods, one or more batteries within the module or pack may experience issues such as excessively low capacity, low voltage, or excessively high voltage. In such cases, it is necessary to adjust the load on the batteries exhibiting abnormal capacity and / or voltage. In the original technology, this was generally achieved using the following two methods: Method 1: Use alligator clips to clamp the battery terminals. On the one hand, alligator clips have weak clamping force and are difficult to establish a firm connection. On the other hand, alligator clips have low overload capacity and generate a lot of heat. Method 2: Welding conductive busbars onto the battery terminals. However, the battery module may be damaged due to the welding process.

[0003] To overcome the above problems, a Chinese utility model patent with the authorization announcement date of July 8, 2022, authorization announcement number CN216928690U, and patentee AVIC Lithium Battery (Luoyang) Co., Ltd., discloses a battery pack charge regulation device.

[0004] The aforementioned device includes a length adjustment mechanism, a width adjustment mechanism, and a probe adjustment mechanism. The length adjustment mechanism is capable of extending and retracting along the length of the battery pack. The width adjustment mechanism is capable of extending and retracting along the width of the battery pack, and both ends of the width adjustment mechanism have positioning holes. A long screw passes through the positioning holes and connects to the end plate positioning holes on the end plate of the battery pack to fix the aforementioned device onto the battery pack. The probe adjustment mechanism includes a sliding connecting seat that is slidably engaged with the length adjustment mechanism and a probe (equivalent to a terminal block) connected to the sliding connecting seat. By moving the sliding connecting seat, the probe can be aligned with the busbar (equivalent to a conductive busbar) of the battery pack.

[0005] The probe includes a charging connection part, a middle part, and a busbar connection part. The charging connection part has a threaded hole for connecting to the charger / discharger using bolts. The busbar connection part is used to connect to the busbar of the battery pack to achieve electrical connection between the busbar connection part and the battery terminals of the battery pack. The sliding connector has a through hole for the probe to pass through. The outer diameter of the charging connection part is larger than the diameter of the through hole. A spring is sleeved on the middle part. One end of the spring abuts against the busbar connection part, and the other end abuts against the sliding connector, so that the spring force holds the busbar connection part against the busbar.

[0006] When using the above device, because the size of the sliding connector is constant, the spacing between the probes connected to both ends of the sliding connector is constant, which makes the above device unable to adapt to batteries of different specifications. Utility Model Content

[0032] In this utility model, for the convenience of those skilled in the art, the sliding direction of the horizontal moving platform is defined as the x-direction, the direction perpendicular to the x-direction in the horizontal plane is defined as the y-direction, and the up-down direction is defined as the z-direction.

[0033] To address the problems in the background technology, the core inventive concept of this utility model is to place one or both of the two terminals on a separate horizontal moving platform, so as to adjust the distance between the two terminals using the horizontal moving platform, thereby accommodating batteries of different specifications.

[0034] Furthermore, both clamps, which are positioned opposite each other, can move along the y-direction to adjust the initial y-direction position of the battery held by the clamps, thereby adjusting the relative y-direction position of the terminals and the battery.

[0035] Furthermore, a positioning plate that can move along the x-direction is provided to adjust the initial position of the battery in the x-direction, thereby adjusting the initial position of the terminal block and the battery in the x-direction. In particular, when one of the terminals cannot move horizontally, this method can be used to adjust the relative position of the immovable terminal block and the battery in the x-direction.

[0036] Furthermore, similar to existing technologies, a spring is used to transform the hard contact force between the terminal and the battery into an elastic contact force. However, unlike existing technologies, the compression of the spring can be adjusted by raising and lowering the lifting platform, thereby adjusting the pressure between the terminal and the battery. This prevents damage to the battery due to excessive pressure or disconnection due to insufficient pressure.

[0037] The present invention will be further described in detail below with reference to the embodiments.

[0038] An embodiment of the battery equalization device provided by this utility model: like Figures 1-4 As shown, in a first basic embodiment, the battery equalization device includes a base plate 3, a first terminal and a second terminal for electrically connecting the battery's conductive busbar to the equalization power supply. A lifting mechanism 1 and a clamping plate for holding the battery are installed on the base plate 3. The lifting mechanism 1 has a lifting platform 1-1, and a horizontal moving platform 6-1 is installed on the lifting platform 1-1. There is one horizontal moving platform 6-1. The first terminal is installed on the horizontal moving platform 6-1, and the second terminal is directly installed on the lifting platform 1-1.

[0039] In use, the first terminal slides horizontally along the x-axis while the second terminal remains stationary, so as to adjust the horizontal distance between the first and second terminals to accommodate batteries of different specifications.

[0040] Reference Figures 1-4 As shown, as a second basic embodiment, the difference between it and the first basic embodiment is that: the number of horizontal moving platforms 6-1 is two and the two horizontal moving platforms 6-1 are used to slide on the same straight line, and the first terminal and the second terminal are respectively installed on different horizontal moving platforms 6-1.

[0041] In use, both the first and second terminals can be slid horizontally along the x-axis to adjust the horizontal distance between them, thus accommodating batteries of different specifications.

[0042] In this utility model, both the lifting mechanism 1 and the horizontal moving platform 6-1 can be purchased directly. In one embodiment, the lifting platform 1-1 is directly provided with a horizontal rail, and the horizontal moving platform 6-1 is guided and moved in cooperation with the lifting platform 1-1 through the horizontal rail. In this case, the position of the horizontal moving platform 6-1 is adjusted by manually pushing the horizontal moving platform 6-1. In other embodiments, the horizontal moving mechanism 6 with the horizontal moving platform 6-1 can also be directly installed on the lifting platform 1-1. The horizontal moving mechanism 6 can also be purchased as a whole.

[0043] In use, first, connect terminal 7 to the equalizing power supply; then, use the horizontal moving platform 6-1 to adjust the distance between the two terminal 7 and align the two terminal 7 with the corresponding conductive busbars; then, lower the lifting platform 1-1 so that the terminal 7 contacts the corresponding conductive busbars; finally, turn on the equalizing power supply to adjust the load.

[0044] To further enhance the applicability of the battery balancing device, in a preferred embodiment, the clamping plate includes a y-direction clamping plate 4 for clamping both sides of the battery in the y direction. The y-direction clamping plate 4 is movably mounted on the base plate 3 in the y direction, and the y-direction clamping plate 4 is configured with a locking structure for locking the y-direction clamping plate 4 after it is in place.

[0045] The core of this embodiment is that both y-direction clamps 4 can move along the y-direction, thereby adjusting the initial position of the battery and thus adjusting the relative position of the terminal 7 and the battery in the y-direction.

[0046] To facilitate understanding by those skilled in the art, the following examples illustrate this type of embodiment.

[0047] In a preferred embodiment, such as Figures 1-4 As shown, the y-direction clamping plate 4 is provided with a y-direction elongated hole 4-1, and the base plate 3 is provided with a threaded hole corresponding to each y-direction elongated hole 4-1. After the bolt passes through the corresponding elongated hole, it is connected to the corresponding threaded hole. The bolt constitutes the locking structure. At this time, the length of the y-direction elongated hole 4-1 in the y direction is the adjustment amount of the y-direction clamping plate 4. The structure is simple.

[0048] In another preferred embodiment, the y-axis clamping plate 4 may also be equipped with a servo linear motor. The output end of the servo linear motor is connected to the y-axis clamping plate 4 to drive the y-axis clamping plate 4 to move along the y-axis. The servo linear motor has a self-locking structure, which constitutes the locking structure described above. The servo linear motor is a prior art technology.

[0049] In other embodiments, the y-axis clamp 4 may also be equipped with a linear power source such as an electric telescopic rod or an electric cylinder with a self-locking function, so that the y-axis clamp 4 can be locked by the self-locking of the linear power source.

[0050] In other embodiments, the positions of the two clamps can remain unchanged. After the battery is placed on the base plate 3, the clamps are fixed to the base plate 3 with bolts. In this case, the battery equalization device is only applicable to batteries with one y-direction width. Alternatively, one of the clamps can move along the y-direction. In this case, the distance between the two clamps is adjustable, which can accommodate batteries with different y-direction widths, but the relative position of the battery terminal 7 and the battery y-direction cannot be adjusted.

[0051] For the first basic embodiment, the initial relative position of the battery and the second terminal must be predetermined during use to ensure that the second terminal contacts the corresponding conductive bar. Operators typically determine the relative position of the second terminal and the corresponding conductive bar by lowering the lifting platform 1-1. Then, the lifting platform 1-1 is raised, and the initial position of the battery is adjusted. This process is repeated until the second terminal contacts the corresponding conductive bar. This process requires repeated raising and lowering of the lifting platform 1-1, making it relatively cumbersome.

[0052] To overcome the above problems, in a preferred embodiment, such as Figures 1-4 As shown, the base plate 3 is also provided with an x-direction positioning plate 5 for positioning the battery in the x-direction. The x-direction positioning plate 5 is provided with an x-direction elongated hole 5-1. The base plate 3 is provided with a threaded hole corresponding to the x-direction elongated hole 5-1. After the bolt passes through the corresponding elongated hole, it is connected to the corresponding threaded hole. The length of the x-direction elongated hole 5-1 along the x-direction is the adjustment amount of the x-direction positioning plate 5.

[0053] During adjustment, the initial position of the x-direction positioning plate 5 can be determined by measuring the relative position of the bolt and the x-direction long hole 5-1 (measuring the distance between the bolt and the two ends of the x-direction long hole 5-1 in the x direction). Alternatively, the lifting platform 1-1 can be lowered, and the initial position of the x-direction positioning plate 5 can be determined by measuring the distance between the lifting platform 1-1 and the x-direction positioning plate 5. Afterward, the initial position of the battery can be determined by adjusting the position of the x-direction positioning plate 5, thereby determining the relative position of the second terminal and the battery. The operation is convenient.

[0054] Of course, when both terminals 7 are set on the horizontal moving platform 6-1, an x-direction positioning plate 5 can also be set.

[0055] In another embodiment, the clamping plate also includes an x-direction clamping plate for clamping the battery on both sides in the x direction. The x-direction clamping plate is provided with x-direction elongated holes 5-1. The base plate 3 is provided with threaded holes corresponding to each x-direction elongated hole 5-1. After the bolt passes through the corresponding elongated hole, it is connected to the corresponding threaded hole. The length of the x-direction elongated hole 5-1 along the x direction is the adjustment amount of the x-direction clamping plate.

[0056] At this time, the clamping plates include the x-axis clamping plate and the y-axis clamping plate 4, which can arbitrarily determine the initial horizontal position of the battery.

[0057] Preferably, in one embodiment, the clamping plate and / or positioning plate is an L-shaped plate, which includes a horizontal plate and a vertical plate. Each elongated hole is provided on the corresponding horizontal plate, and the vertical plate and the horizontal plate are detachably connected by bolts or snap-fits. The horizontal plate is used to clamp or position the bottom of the battery, and the vertical plate is used to clamp or position the upper middle part of the battery.

[0058] In other embodiments, the clamping plate can also be a rectangular plate, in which case long bolts are needed to connect the clamping plate to the base plate 3; the horizontal plate and the vertical plate can also be integrally formed.

[0059] The first and second terminals are described below.

[0060] like Figures 1-4 As shown, the terminal block 7 includes, from top to bottom, a charging / discharging connection section 7-1, a transition section 7-2, and a conductive busbar connection section 7-3; both the lifting platform 1-1 and the horizontal moving platform 6-1 are provided with through holes for the transition section 7-2 to pass through, or both horizontal moving platforms 6-1 are provided with through holes for the transition section 7-2 to pass through; the outer diameter of the charging / discharging connection section 7-1 is larger than the diameter of the through hole, and the transition section 7-2 is fitted with a compression spring 8, one end of which is used to directly or indirectly press against the lifting platform 1-1 or the horizontal moving platform 6-1, and the other end is used to directly or indirectly press against the conductive busbar connection section 7-3.

[0061] The charging / discharging connection section 7-1 is provided with a connection hole 7-4 for connecting to the equalizing power supply. The connection hole 7-4 can be a threaded hole, so that the conductive bus can be connected to the charging / discharging connection section 7-1 with bolts, and the conductive bus can be connected to the equalizing power supply. At this time, it is not necessary to weld the conductive bus to the charging / discharging connection section 7-1.

[0062] exist Figures 1-4 In the illustrated embodiment, the outer diameters of the transition section 7-2 and the conductive busbar connection section 7-3 are equal. Therefore, a groove 7-5 is provided at the junction of the transition section 7-2 and the conductive busbar connection section 7-3. A retaining ring 9 is fitted into the groove 7-5, and another retaining ring 9 is fitted onto the transition section 7-2. The compression spring 8 is compressed between the two retaining rings 9 and is used to apply a downward elastic force to the terminal 7 through the retaining rings 9. At this time, one end of the compression spring 8 indirectly abuts against the lifting platform 1-1 or the horizontal moving platform 6-1, and the other end indirectly abuts against the conductive busbar connection section 7-3.

[0063] In other embodiments, one end of the compression spring 8 can also directly press against the lifting platform 1-1 or the horizontal moving platform 6-1; the outer diameter of the conductive busbar connecting section 7-3 is larger than the outer diameter of the transition section 7-2, and the conductive busbar connecting section 7-3 is provided with a threaded hole, and the lower end of the transition section 7-2 is provided with an external thread, so that the conductive busbar connecting section 7-3 and the transition section 7-2 can be detachably connected by a threaded connection, ensuring that the terminal 7 can be properly assembled. At this time, the other end of the compression spring 8 can directly press against the conductive busbar connecting section 7-3.

[0064] The terminal block 7 is made of conductive material. To prevent leakage, in a preferred embodiment, the lifting platform 1-1 or the horizontal moving platform 6-1 is provided with a mounting plate (i.e., the first mounting plate 1-2 and the second mounting plate 6-2) for mounting the terminal block 7. The mounting plate is made of insulating material, and perforations for the transition section 7-2 to pass through are provided on the mounting plate.

[0065] In other embodiments, an insulating sleeve may also be provided between the hole wall of the perforation and the transition section 7-2.

[0066] In this utility model, both the lifting mechanism 1 and the horizontal moving platform 6-1 can adopt conventional structures in mechanical design. For ease of understanding by those skilled in the art, the following description is provided in conjunction with... Figures 1-3 A brief explanation is provided.

[0067] The lifting mechanism 1 is a screw and nut lifting mechanism. The lifting platform 1-1 constitutes the output end of the screw and nut lifting mechanism. The screw and nut lifting mechanism is equipped with a locking device for locking the corresponding screw.

[0068] The screw nut lifting mechanism includes a track plate fixed on the base plate 3, a reinforcing plate 2 to strengthen the connection between the track plate and the base plate 3, a vertically extending track on the track plate and a lifting seat that slides with the track guide, the lifting seat being threadedly connected to the lifting screw, a handwheel and a bearing (connected to the smooth section of the lifting screw) connected to the upper end of the lifting screw to prevent it from moving up and down, the bearing being installed on the upper surface of the track plate. The first locking device 1-3 includes a set screw, a handle and a fixed seat, the fixed seat being fixed on the bearing seat of the bearing, the set screw being threadedly connected to the fixed seat, and the set screw being tightened by turning the handle to lock the lifting screw.

[0069] The lifting seat is fixedly connected to the lifting plate via an L-shaped adapter plate. The first mounting plate 1-2 is mounted on the lifting plate, and a reinforcing plate 2 is provided at the corner of the adapter plate. The lifting seat, adapter plate, lifting plate, and first mounting plate 1-2 work together to lift and form the lifting platform 1-1.

[0070] Of course, the lifting mechanism 1 can also be a commonly used lifting mechanism 1 such as a worm gear lifting mechanism or a linear motor lifting mechanism, and the output end of the lifting mechanism 1 constitutes the lifting platform 1-1.

[0071] Similarly, a screw and nut horizontal sliding mechanism (i.e., horizontal moving mechanism 6) is installed on the lifting platform 1-1. The horizontal moving platform 6-1 (or horizontal slide) constitutes the output end of the screw and nut horizontal sliding mechanism. Both the screw and nut lifting mechanism and the screw and nut horizontal sliding mechanism are equipped with a second locking device 6-3 for locking the corresponding screw.

[0072] The horizontal sliding mechanism of the lead screw and nut also includes a corresponding track plate, a horizontal lead screw, bearings, a handwheel, and a horizontal sliding seat. The track plate is mounted on the lifting plate, and a second mounting plate 6-2 is mounted on the horizontal sliding seat. The horizontal sliding seat and the second mounting plate 6-2 together constitute the horizontal moving platform 6-1. The second locking device 6-3 also includes a corresponding set screw, handle, and fixed seat.

[0073] Of course, the horizontal moving mechanism 6 can also be a commonly used horizontal moving mechanism 6 such as an electric push rod moving mechanism or a linear motor moving mechanism, and the output end of the horizontal moving mechanism 6 constitutes the horizontal moving table 6-1.

The battery balancing unit is any one of the embodiments of the battery balancing device of this utility model, and will not be described in detail here.

[0075] The equalization power supply is preferably a constant voltage source, but it can also be a charge / discharge machine.

[0076] The battery equalization device and the equalization power supply can be electrically connected via wires or busbars.

[0077] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
