Description

Technical Field

[0001] The utility model belongs to the field of CT equipment, in particular to a battery automatic rotation angle CT detection system. Background Art

[0002] Lithium-ion power batteries are widely used in portable electronics, new energy vehicles, energy storage, and many other fields. Power batteries are generally divided into three types: prismatic, soft-pack, and cylindrical. "Lamination" and "winding" are the two processes used to produce these batteries. Compared to wound batteries, laminated batteries offer advantages in performance, integrity, and space utilization. Current inspection methods, industrial CT and X-rays, are the most powerful tools for detecting failures in new energy batteries. These solutions not only observe the internal structure of the battery in a non-destructive manner, but also magnify battery samples by hundreds of times to identify subtle defects. To address battery safety risks, industrial CT scans samples and analyzes the characteristics of issues such as electrode fracture, electrode wrinkles, electrode alignment, and internal foreign matter in CT images. This allows analysis of the internal structure of batteries after safety testing.

[0003] The current battery testing equipment has a single adjustment method, which cannot perform thorough testing on some small batteries, resulting in inaccurate test data. Utility Model Content
