A Unified Model for Active Battery Equalization Systems

no code implementations6 Mar 2024 Quan Ouyang, Nourallah Ghaeminezhad, Yang Li, Torsten Wik, Changfu Zou

Lithium-ion battery packs demand effective active equalization systems to enhance their usable capacity and lifetime.

Analysis of potential lifetime extension through dynamic battery reconfiguration

no code implementations21 Jul 2023 Albert Skegro, Changfu Zou, Torsten Wik

Due to factors such as cell position in the pack and variations in the manufacturing process, the packs exhibit variations in the performance of their constituent cells.

MINN: Learning the dynamics of differential-algebraic equations and application to battery modeling

no code implementations27 Apr 2023 Yicun Huang, Changfu Zou, Yang Li, Torsten Wik

The concept of integrating physics-based and data-driven approaches has become popular for modeling sustainable energy systems.

Battery Capacity Knee-Onset Identification and Early Prediction Using Degradation Curvature

no code implementations23 Apr 2023 Huang Zhang, Faisal Altaf, Torsten Wik

A curvature-based identification of a knee and its onset is proposed, which relies on the discovery of a distinctly fluctuating behavior in the transition between an initial and a final stable acceleration of the degradation.

Interpretable Battery Cycle Life Range Prediction Using Early Degradation Data at Cell Level

no code implementations26 Apr 2022 Huang Zhang, Yang Su, Faisal Altaf, Torsten Wik, Sebastien Gros

For that reason, various data-driven methods have been proposed for point prediction of battery cycle life with minimum knowledge of the battery degradation mechanisms.
