Technical Field

[0002] Automated lithium battery testing equipment is closely related to the rapid development of the global new energy industry. With the increasing demand for high-performance lithium batteries in fields such as electric vehicles, smartphones, and energy storage systems, the quality and safety of lithium batteries have become critical issues. Therefore, automated lithium battery testing equipment has emerged as a key tool for improving production efficiency, ensuring product quality, and guaranteeing safe use.

[0003] Existing lithium battery testing equipment generally does not have the capability to test internal resistance. Internal resistance testing of lithium batteries is a key indicator for evaluating battery performance and health status. Excessive internal resistance may lead to battery overheating, reduced efficiency, and even affect battery safety.

[0004] Therefore, we propose an automated lithium battery testing device to solve this problem. Utility Model Content

The knob 19 is rotatably connected to the right side of the side plate 15, thus realizing the installation and disassembly functions of the equipment box 10.

[0025] In this embodiment, rectangular plates 26 are fixedly connected to the left side of both clamping plates 11, and a bidirectional threaded rod 23 is rotatably connected inside the equipment box 10.

The two trapezoidal plates 24 are slidably connected to the outside of the same guide post 25, thereby realizing the guiding function of the trapezoidal plates 24.

[0026] In this embodiment, a mounting column 20 is fixedly connected to the front side of the equipment box 10, an arc plate 21 is fixedly connected to the front end of the mounting column 20, a second motor 22 is fixedly connected to the rear side of the arc plate 21, and the output end of the second motor 22 is fixedly connected to the front end of the bidirectional threaded rod 23, thereby realizing the power drive function of the bidirectional threaded rod 23.
