[0021] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0022] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the outlines of the corresponding components themselves; the directional words used, such as "upper", "lower", "top", "bottom", "horizontal" and "vertical", are defined based on the usage habits of the battery stack provided by the present disclosure. Specifically, refer to Figure 1 In the direction of the drawings shown, the side indicated by the Z arrow is the top and the top, and the opposite side is the bottom and the bottom. In addition, the X and Y directions refer to the horizontal direction, and the Z direction refers to the vertical direction. The terms used in this disclosure, such as "first" and "second", are used to distinguish one element from another element and do not have order and importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements.

[0023] Reference Figure 1The present disclosure provides a leveling device for a battery stack body, which can be used to adjust the horizontal inclination and height of the battery stack body 1 relative to the installation base surface according to the installation environment of the battery stack body 1, so that the battery stack body 1 can always meet the installation requirements on the installation base surface. It should be noted that the horizontal inclination angle in the present disclosure refers to the angle between a reference surface of the battery stack body 1 and the installation base surface in the X direction, Y direction or Z direction. The reference surface can be, for example, the bottom surface or side surface of the battery stack body 1. The installation base surface can be the sea surface or the road surface. The present disclosure does not limit this. The installation base surface can be set in the XY plane, or in the YZ plane, or in the XZ plane. The present disclosure does not limit this. In the embodiment provided in the present disclosure, the installation base surface is set in the XY plane as an example for expansion. The leveling device may include a detection unit 2, a control unit and an adjustment unit 3. The detection unit 2 can be used to analyze the installation environment, battery stack characteristics, and detect the current values ​​of the horizontal inclination and height of the battery stack body 1. In the present disclosure, the battery stack characteristics refer to the quality information of the battery stack, the dynamic information of the battery stack life value, SOH (State Of Health), etc., to improve the versatility and applicability of the adjustment device. The control unit can be connected to the detection unit 2, and is used to determine the adjustment value of the horizontal inclination and height of the battery stack body 1 according to the detection signal of the detection unit 2, so as to ensure the calculation accuracy of the required adjustment angle and height of the battery stack body 1. The adjustment unit 3 may include a plurality of support rods, which extend in a vertical direction and are supported in parallel to each other at the bottom of the battery stack body 1. The control unit can control the plurality of support rods separately, so as to be able to flexibly adjust the height of each support rod according to actual needs, so that the battery stack body 1 can be used to maintain a horizontal state and be located at a preset height, that is, Figure 1 It should be noted that the preset height in the present disclosure refers to a fixed position selected by the battery stack body 1 according to installation and working requirements. When the support height of one or several support rods can meet the preset height for the battery stack body 1, it is only necessary to adjust the support height of the remaining support rods. In this way, the battery stack body 1 can be kept in a horizontal state while meeting the height requirements of the battery stack body 1.

[0024] Through the above technical scheme, the control unit and the detection unit 2 analyze the installation environment and stack characteristics of the battery stack body 1 in real time, and monitor the current values ​​of the horizontal inclination and height of the battery stack body 1 in real time, and the adjustment unit 3 automatically adjusts the preset horizontal inclination and height of the battery stack body 1 in real time, so that the battery stack body 1 can adapt to different installation base surfaces and environmental conditions, effectively improves the stability of the battery stack body 1 during operation and installation, reduces the risk of performance degradation or failure caused by tilt, and avoids frequent and unnecessary adjustments to the battery stack body 1, preventing the battery stack from becoming unstable, having performance degradation or failing due to adjustment.

[0025] Further, the installation environment may include the levelness and slope of the installation base surface, the levelness refers to the flatness of the installation base surface in the XY plane, the YZ plane, or the XZ plane, and the slope refers to the degree of inclination of the installation base surface relative to the XY plane, the YZ plane, or the XZ plane. The detection unit 2 may be configured to determine the preset values ​​of the horizontal inclination angle and height of the battery stack body 1 according to the installation environment and the characteristics of the battery stack, and the control unit may be configured to determine the adjustment value according to the preset value. Thus, the leveling device can monitor and evaluate the horizontal inclination angle and height of the battery stack body in real time through the detection unit 2. By analyzing the characteristics of the installation environment and the design parameters of the battery stack body 1, the detection unit 2 can determine an ideal preset value of the horizontal inclination angle and height, and accordingly, the control unit can receive data from the detection unit 2 and calculate the adjustment value according to the preset value. In the embodiment provided in the present disclosure, the preset value may be a specific value, such as 5°, or a certain range of values, such as 3°~7°, and the present disclosure does not limit this, so as to enable the battery stack body 1 to make corresponding adjustments under different working conditions. When the inclination angle of the battery stack body 1 exceeds the range defined by the preset value, the control unit will automatically start the adjustment unit 3 to adjust the inclination angle of the battery stack body 1 to ensure that the battery stack body 1 returns to the preset working state, so as to effectively avoid frequent adjustments of the battery stack body 1 due to small tilts, thereby helping to prevent instability and repeated shaking of the battery stack body 1, and effectively improving the overall operating efficiency and safety of the battery stack.

[0026] According to some embodiments provided by the present disclosure, the control unit may include a first expert controller and a second expert controller. In the embodiments provided by the present disclosure, the first expert controller and the second expert controller may be respectively composed of an expert control system (ECS). The first expert controller may be used to determine the adjustment value according to the current value to drive the adjustment unit 3, that is, the first expert controller may receive the current value of the horizontal inclination and height of the battery stack body 1 in real time, and calculate the adjustment value of the battery stack body 1 according to the difference between these current values ​​and the preset value, and generate corresponding adjustment instructions to adjust the support rod, so as to ensure that the battery stack body 1 is restored to the preset working state. The second expert controller may be used to determine the adjustment value according to the characteristics of the battery stack and the installation environment to drive the adjustment unit 3, that is, the second expert controller is used to receive the analysis data of the characteristics and design parameters of the installation environment and the battery stack by the detection unit 2, and determine the support rod suitable for the required adjustment and the adjustment value of the support rod based on the analysis data, so that the corresponding support rod is adjusted in a targeted manner. In the embodiments provided by the present disclosure, the first expert controller and the second expert controller may work independently, but the outputs of the first expert controller and the second expert controller may be integrated to select the best adjustment value. For example, the output of one of the controllers can be selected according to the priority, or the outputs of the two controllers can be weighted averaged to obtain a more balanced adjustment instruction. In the embodiment provided by the present disclosure, the detection unit 2 can be configured with a feedback mechanism, and the feedback mechanism can be the inclination sensor mentioned below, so as to monitor the effect of the adjustment unit 3 on the battery stack body 1 in real time. The feedback mechanism can feed back the results to the two controllers, thereby facilitating real-time monitoring of the battery stack body 1 and performing dynamic adjustment and optimization. Such a design can effectively implement a flexible and accurate adjustment strategy for the battery stack body 1, ensure that the battery stack body 1 maintains stable and efficient operation in a complex working environment, improve the response speed of the leveling device, and enhance its adaptability and intelligence level.

[0027] Reference Figure 1 The number of support rods may be at least two, and the two support rods are supported at two corners of the bottom surface of the battery stack 1 in a one-to-one correspondence. Figure 1, the number of support rods can be four, and the four support rods can be supported one by one at the four corners of the bottom surface of the battery stack body 1, so as to effectively disperse the weight of the battery stack body 1 and reduce deformation or damage caused by excessive local force. At the same time, the four support rods can be generally constructed to support the frame relatively stably, enhance the stability of the support of the battery stack body 1, and reduce the risk of tilting or overturning of the battery stack body 1. For example, when the installation base is a slope or an uneven ground, the support height of each support rod can be independently adjusted to achieve accurate horizontal adjustment of the battery stack body 1 on the slope or uneven ground, ensuring that the working performance of the battery stack body 1 is not affected. It should be noted here that the present disclosure does not limit the number of support rods, as long as the adjustment and support needs are met, and can be arranged according to the specific structure of the battery stack body 1. For example, when the bottom surface of the battery stack body 1 is triangular, the number of support rods can be three, and the three support rods can be supported one by one at the three corners of the bottom of the battery stack body 1.

[0028] Reference Figure 1 The support rod can be constructed as a telescopic rod 31 that can be telescoped in the vertical direction to adjust the support height of the battery stack body 1 by telescoping. When the adjustment unit includes the first driving component mentioned below, the telescopic rod 31 is electrically connected to the first driving component, and the first driving component can be connected to the control unit, for example, it can be a signal connection, so that the telescopic rod 31 can quickly adjust the support height according to the adjustment needs to adapt to different ground conditions, and achieve precise horizontal adjustment of the battery stack body 1, thereby avoiding the tilting or tipping of the battery stack body 1 due to improper support of the telescopic rod 31. In addition, the design of the telescopic rod 31 makes it more convenient to adjust the height, improves the adjustment efficiency, and reduces the complexity of the adjustment and the demand for labor.

[0029] Reference Figure 1 The adjustment unit 3 may also include a support base 32 that is fitted on the installation base surface, so as to effectively disperse the load of the battery stack body 1 through the support base 32, enhance the stability of the battery stack body 1 in various environments, and reduce the risk of tilting or tipping. One end of the telescopic rod 31 can be fixedly connected to the battery stack body 1, and the other end of the telescopic rod 31 can be slidably connected to the support base 32 in the horizontal direction. When the installation base surface is deformed or settled, the sliding design allows the telescopic rod 31 to appropriately adjust the installation position of the battery stack body 1 in the horizontal direction. At the same time, during the installation process, it can also ensure the accurate positioning of the battery stack body 1, reducing the difficulty of installation. In addition, when the battery stack body 1 needs to be maintained or repaired, the sliding connection makes it more convenient to adjust and move the battery stack body 1, saving time and manpower.

[0030] Reference Figure 1 and Figure 2The telescopic rod 31 may include a first rod 311 and a second rod 312. The top support of the first rod 311 may be at the bottom of the battery stack body 1, the top of the second rod 312 may be coaxially sleeved on the outside of the first rod 311, and the bottom end of the second rod 312 may be supported on the top surface of the support base 32. Such a design can effectively enhance the strength of the telescopic rod 31 itself and the stability of the connection with other components, reduce the risk of shaking or tilting caused by external forces, and ensure the safety in the process of adjusting the battery stack body 1 and supporting the battery stack body 1. The adjustment unit 3 may include a first driving component, such as a driving motor, and the output shaft of the first driving component may be connected to one of the first rod 311 and the second rod 312, such as the first rod 311, so that the first rod 311 can reciprocate in the vertical direction relative to the second rod 312, thereby realizing extension or retraction in the vertical direction, so as to be able to quickly and accurately adjust the height of the battery stack body 1 to meet the needs of different working scenes. Furthermore, since the first driving component is connected to the control unit, it not only realizes the automatic adjustment of the supporting height of the telescopic rod 31, thereby improving the operating efficiency and the control height, but also effectively prevents the battery stack body 1 from tilting or overturning due to improper support, thereby enhancing the overall safety.

[0031] Reference Figure 1 and Figure 2 The adjustment unit 3 may also include a guide rail 33, a slide bar 34 and a second driving component. The guide rail 33 may extend in the horizontal direction and be fixedly mounted on the side of the support base 32 that is away from the mounting base surface, so as to provide stable support for the support rod and the slide bar 34, thereby effectively reducing the shaking of the slide bar 34 during movement and improving the stability of the overall structure. The bottom end of the slide bar 34 may be slidably connected to the guide rail 33 in the horizontal direction, and the top end of the slide bar 34 may be fixedly connected to the telescopic rod 31, so as to be able to move along the slide bar 34 with the telescopic rod 31, and then be adjusted at different positions, and be able to adapt to different working environments and requirements, thereby improving the flexibility of the adjustment device operation. The output end of the second driving component (not shown in the figure) may be connected to the slide bar 34 to drive the slide bar 34 to reciprocate in the horizontal direction relative to the guide rail 33. Through the control of the second driving component, the slide bar 34 may be accurately moved to ensure the accurate positioning of the battery stack body 1 during installation and reduce errors. Refer to Figure 2 In the embodiment provided in the present disclosure, the guide rail 33 can be constructed as an integrally formed structure with the support base 32 to further improve the overall effect of the leveling device and the stability of the movement of the battery stack body 1 driven by the slide bar 34.

[0032] Furthermore, in the embodiment provided by the present disclosure, the second driving component may include a cylinder body disposed on a support base 32 and a piston rod that can be extended and retracted in the cylinder body, and the slide bar 34 may be connected to the piston rod so as to be driven by the piston rod to reciprocate in the horizontal direction along the guide rail 33, so that the position of the slide bar 34 can be adjusted during the smooth reciprocating movement of the piston rod on the guide rail 33, so that the support rod can support the battery stack body 1 at different positions in the horizontal direction, thereby ensuring the stability and flexibility of the horizontal position adjustment of the battery stack body 1. The specific working principle of the piston rod and the cylinder body is well known to those skilled in the art and will not be repeated here.

[0033] Reference Figure 1 , the detection unit 2 may include a tilt sensor 21 embedded in the end plate of the battery stack body 1. In the embodiment provided in the present disclosure, the tilt sensor 21 may be, but is not limited to, a gravity type, a liquid pendulum type, a laser type, etc. For example, it may be a gyroscope or a gravimeter, etc., to measure the horizontal tilt angle of the battery stack body 1 in real time, and to timely feedback the working state of the battery stack body. The control unit may include a data transmission module, which may be the first expert controller and the second expert controller mentioned above or one of them. The data transmission module may be connected to the tilt sensor 21 signal to receive the angle signal detected by the tilt sensor 21, and can accurately calculate the required adjustment angle. When the tilt angle exceeds the set range, the data transmission module transmits an electrical signal to the first drive motor mentioned above, and starts the first drive motor to drive the corresponding support rod to adjust to the appropriate support height, so that the battery stack body 1 always maintains a horizontal state. In addition, by embedding the tilt sensor 21 inside the end plate, it is possible to save external space, reduce installation complexity, and improve the overall effect of the leveling device.

[0034] Reference Figure 1 , the detection unit 2 in the present disclosure may also include a laser level 22 and a camera (not shown in the figure). The laser level 22 can be set on one side of the horizontal direction of the battery stack body 1 to emit a horizontal laser beam, providing a clear reference line, so that the measurement of the tilt angle is more accurate. The camera can collect the horizontal laser beam, and the camera can be configured to send an electrical signal to the control unit when an angle is observed between the battery stack body 1 and the horizontal laser beam, so as to ensure the continuity and timeliness of the monitoring process. Specifically, when the control unit receives the signal, data analysis can be performed to calculate the tilt angle and tilt direction of the battery stack body 1, so as to adjust the support rod accordingly. In the embodiment provided in the present disclosure, the four support rods can be driven to extend or retract to the same height at the same time to adjust the setting height of the battery stack body 1 in the vertical direction.

[0035] Reference Figure 3 and Figure 4, accordingly, the present disclosure also provides a method for leveling a battery stack body, which can be applied to the leveling device provided by the present disclosure, and the leveling method includes step S200, analyzing the installation environment and battery stack characteristics of the battery stack body 1, and detecting the current values ​​of the horizontal inclination and height of the battery stack body 1. Before step S200, the method may also include step S100, setting the battery stack body 1 on the installation base surface by the adjustment device, when the bottom surface contour of the battery stack body 1 is configured as a quadrilateral, the number of support rods may be four, and the four support rods are respectively supported at the four vertices of the bottom surface of the battery stack body 1. After step S200, it also includes step S300, determining the adjustment values ​​of the horizontal inclination and height of the battery stack body 1 according to the installation environment, battery stack characteristics and current values. In this step, the control unit can calculate the required adjustment angle of the battery stack body 1 and the required adjustment support height of each support rod, that is, the adjustment value, according to the preset value of the battery stack body 1. After step S300, step S400 is also included, in which a plurality of support rods are controlled according to the adjustment value to adjust the horizontal inclination angle of the battery stack body 1, and a control unit separately controls a plurality of support rods arranged at the bottom of the battery stack body 1 to adjust the horizontal inclination angle of the battery stack body 1. After step S400, step S500 is also included, in which the detection unit 2 feeds back the adjusted position and angle to the control unit in real time to determine whether the battery stack body 1 meets the placement requirements, that is, whether the current value of the battery stack body 1 meets the preset value. When the battery stack body 1 meets the placement requirements, it is determined that the adjustment is completed. If not, steps S300-S500 are repeated. This leveling method has all the beneficial effects of the above-mentioned leveling device, which will not be repeated here. In addition, the specific operation process of the leveling method provided in the present disclosure can be completed using the above-mentioned leveling device.
