AI Technical Summary

Technical Problem

In the existing technology, the electrical isolation effect at the positioning holes of the insulation structure and the isolation structure is poor, which leads to safety risks in individual battery cells. In addition, the design of the positioning holes is complex and difficult to be compatible with different battery models.

Method used

The positioning requirements are met by using the protrusions of the insulating structure and the through holes of the isolation structure, eliminating the need for positioning holes. The electrical isolation between the electrode assembly and the housing is improved by heat-sealing the insulating and isolation structures. A CCD camera is used to identify and match the protrusions and through holes, simplifying the assembly process.

Benefits of technology

It improves the safety of individual battery cells, simplifies the assembly process, enhances compatibility with different battery models, and saves tooling costs and time.
