[0023] To address the problem of cumbersome operation and low testing efficiency caused by frequent plugging and unplugging of test cables during battery testing in existing technologies, such as... Figures 1 to 3 As shown, this application provides a battery testing device, which includes a testing platform 1, a power supply component 3, and a nut removal and installation component 4.

[0024] The testing station 1 is used to support the battery 2 to be tested, providing a stable physical platform for subsequent testing operations.

[0025] The power-conducting component 3 includes a wire fixing member 31 and multiple wires 32. One end of each wire 32 is electrically connected to the detection device, and the other end is used to form an electrical connection with the cell terminal of the battery 2 under test. Each wire 32 is fixedly installed on the wire fixing member 31. The number of wires 32 is adapted to the number of cell terminals to be connected on the battery 2 under test. When the wire fixing member 31 is connected to the battery 2 under test, each wire 32 can be electrically connected to the corresponding cell terminal on the battery 2 under test, thereby achieving stable transmission of the detection signal.

[0026] The nut removal and installation assembly 4 is set on the test table 1 and located on the side of the battery 2 under test with the cell terminal. It is used to fasten the nut to the cell terminal of the battery 2 under test, or to remove the nut from the cell terminal of the battery 2 under test, so as to facilitate reliable connection or separation between the cell terminal and the wire 32, and improve the operation efficiency and automation of the test process.

[0027] like Figure 4 As shown in a specific embodiment of this application, the wire fixing member 31 is provided with multiple wire grooves 311, and each wire 32 is sequentially snapped into the corresponding wire groove 311 to achieve orderly fixing and positioning of the wire 32 on the wire fixing member 31. Each wire groove 311 is also provided with a through hole 312, the position of which corresponds to the cell terminal of the battery 2 to be tested, so that the cell terminal can pass through the through hole 312 and make electrical connection with the wire 32 located in the wire groove 311, thereby ensuring accurate docking between the wire 32 and the cell terminal, improving the reliability of the connection and the convenience of operation.

[0028] like Figure 4 As shown, in a specific embodiment of this application, the power-conducting component 3 further includes a wire clamping plate 33, which is connected to the wire fixing member 31 and presses against the wire 32 to press the wire 32 tightly in the wire groove 311, preventing the wire 32 from loosening, shifting or falling off during the operation of the device, thereby ensuring a reliable electrical connection between the wire 32 and the battery cell terminal, and improving the structural stability and electrical connection reliability of the power-conducting component 3 during the detection process.

[0029] like Figures 1 to 3 As shown in a specific embodiment of this application, a wire rack 5 is also provided on the testing table 1. The wire rack 5 is used to support and place the power-conducting component 3, so that the power-conducting component 3 can be stably placed on the testing table 1 in the non-working state or standby state, avoiding damage or connection failure of the wire 32 due to dragging, tangling or accidental contact. At the same time, it is convenient for operators to install, adjust or remove the power-conducting component 3, which helps to improve the overall ease of use and operational safety of the device.

[0030] like Figure 5 As shown in a specific embodiment of this application, the nut removal and installation assembly 4 includes a guide base 41, a slide 42, and a nut removal and installation device 43. The guide base 41 is fixedly mounted on the testing platform 1, and its extension direction is parallel to the arrangement direction of the battery cell terminals on the battery to be tested 2, providing a stable guide and movement path for the slide 42. The slide 42 slidably engages with the guide base 41 and can reciprocate along the extension direction of the guide base 41, thereby adjusting its position in the battery cell terminal arrangement direction. The nut removal and installation device 43 is mounted on the slide 42 and moves synchronously with the slide 42, used to perform tightening or loosening operations on the nuts on the battery cell terminals of the battery to be tested 2. By adjusting the position of the slide 42 on the guide base 41, the nut removal and installation device 43 can accurately correspond to the battery cell terminals at different positions, improving the positioning accuracy and work efficiency of the nut removal and installation operation. The nut removal and installation device 43 can specifically be an electric wrench, etc.

[0031] like Figure 5As shown, in a specific embodiment of this application, the slide 42 includes a first slide 421 and a second slide 422. The first slide 421 is slidably fitted onto the guide base 41 along the extending direction of the guide base 41, and is used to drive the nut removal / installation device 43 to adjust its position parallel to the direction of the battery cell terminals. The second slide 422 is slidably fitted onto the first slide 421 along the direction closer to or further away from the battery 2 to be tested, and is used to drive the nut removal / installation device 43 to adjust its position relative to the axial direction of the battery cell terminals. The nut removal / installation device 43 is fixedly installed on the second slide 422. Through the relative movement of the first slide 421 and the second slide 422, the position of the nut removal / installation device 43 can be adjusted in two directions, enabling it to accurately correspond to the battery cell terminals at different positions and spacings on the battery 2 to be tested, thereby improving the positioning accuracy and operational adaptability of the nut removal / installation operation.

[0032] like Figures 1 to 3 As shown, in a specific embodiment of this application, the nut removal and installation assembly 4 is configured as at least a pair and is respectively arranged on opposite sides of the battery 2 to be tested. It is used to perform tightening or loosening operations on the nuts on the cell terminals from both sides of the battery simultaneously or independently, thereby improving the balance, operational stability and adaptability to the battery structure of the nut removal and installation process, and ensuring that the cell terminals and wires can be reliably connected during the testing process.

[0033] like Figures 1 to 3 As shown, in a specific embodiment of this application, the testing platform 1 includes a support base 11, which serves as the direct support structure for the battery 2 to be tested. Multiple rolling elements 111, such as rollers, are mounted on the upper surface of the support base 11. These rolling elements 111 are spaced apart on the bearing surface of the support base 11 to reduce the frictional resistance between the battery 2 to be tested and the support base 11 during placement or movement. When the battery 2 to be tested is placed on the support base 11, its bottom surface forms rolling contact with the multiple rolling elements 111. This ensures stable support of the battery while facilitating fine-tuning or movement of the battery by the operator, improving the positioning flexibility and operational convenience of the battery on the testing platform 1.

[0034] like Figures 1 to 3 As shown, in a specific embodiment of this application, the extension direction of the testing platform 1 is parallel to the arrangement direction of the cell terminals on the battery 2 to be tested. The battery 2 to be tested is placed or removed from one end of the testing platform 1 to facilitate the loading and unloading of the battery by the operator. At least one limiting pin 112 is provided at the other end of the testing platform 1. The limiting pin 112 is fixed on the support base 11 and is used to limit the movement direction of the battery 2 after it is placed in, so as to prevent the battery from being displaced along the extension direction of the testing platform 1 or from falling off the support base 11 during the testing process, thereby improving the positioning stability and operational safety of the battery during the testing process.

[0035] like Figures 1 to 3 As shown, in a specific embodiment of this application, the testing table 1 further includes a height-adjustable table 12, which serves as an adjustment support platform for the testing table 1. A support base 11 and a nut disassembly and assembly assembly 4 are fixedly installed on the table. Through the height adjustment function of the height-adjustable table 12, the relative height of the support base 11 and the nut disassembly and assembly assembly 4 relative to the operator can be adjusted to adapt to the testing requirements of batteries of different specifications and improve the applicability and operational comfort of the device in different application scenarios.

[0036] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
