AI Technical Summary

⚠Technical Problem

In existing technologies, when disassembling end-of-life electric vehicle batteries by relying on large language models, geometric interference in the real physical space is ignored, resulting in an undesirable disassembly sequence.

⚗Method used

Based on the three-dimensional model of the retired power battery, a Boolean six-way interference matrix is ​​constructed to generate an initial disassembly sequence. The initial disassembly sequence is also generated through a large language model. Geometric constraints are applied in conjunction with the Boolean six-way interference matrix to correct disassembly steps that do not meet the interference constraints, thus ensuring the feasibility of the disassembly sequence.

🎯Benefits of technology

It significantly improves the feasibility and safety of battery disassembly sequences, ensures that the disassembly process can be performed in a real physical space, and enhances the level of automation and economic benefits of disassembly.

Abstract

This invention relates to a method and apparatus for generating a dismantling sequence for retired power batteries. The method includes constructing a Boolean six-way interference matrix; inputting a structured prompt template into a large language model to generate an initial dismantling sequence; determining whether each dismantling step in the initial dismantling sequence satisfies interference constraints based on the Boolean six-way interference matrix, and retaining the first dismantling step that satisfies the interference constraints; when there is a second dismantling step that does not satisfy the interference constraints, retrying the second dismantling step in a different direction or backtracking to the nearest branchable part node in the initial dismantling sequence to obtain a third dismantling step that satisfies the interference constraints; and obtaining the battery dismantling sequence based on the first and third dismantling steps. This invention constructs a Boolean six-way interference matrix based on the three-dimensional model of the battery, and constrains the initial dismantling sequence through the Boolean six-way interference matrix, combining the actual physical space of the battery with the dismantling process, thereby increasing the feasibility of the battery dismantling sequence.
