Summary

• What is new: Introduces a novel, hypergraph-based approach to model active battery equalization systems, offering a unified mathematical model for the first time.
• Why this is important: Lack of a unified mathematical model for analyzing, comparing, and optimizing lithium-ion battery pack equalization systems.
• What the research proposes: A hypergraph-based approach creating a unified model that correlates battery cells and equalizers, facilitating analysis and optimization of equalization systems.
• Results: Demonstrated that equalization time is inversely related to the second smallest eigenvalue of the hypergraph’s Laplacian matrix, simplifying system selection and design.
