Conclusion This paper proposed a Battery Phase Space Warping (BPSW) algorithm as a means to monitor the aging process of lithium-ion batteries (LIBs). The BPSW algorithm reconstructs a phase space (PS) that is qualitatively equivalent to the original battery system using the voltage signals from battery discharge.
Volume 624, 30 December 2024, 235607 BPSW monitors battery aging by reconstructing voltage signals into phase space. Trajectory warping in phase space reflects changes in battery parameters. BPSW uses local polynomial regression for reference trajectories of health. BPSW separates fast and slow variables, minimizing interference from discharge.
The theory of phase space warping originates from the qualitative analysis of slowly time-varying dynamic systems. The slow degradation phenomenon during the charge and discharge cycles of LIBs is characterized by slowly varying parameters, while the corresponding voltage and current signals are considered fast-varying.
Trajectory warping in phase space reflects changes in battery parameters. BPSW uses local polynomial regression for reference trajectories of health. BPSW separates fast and slow variables, minimizing interference from discharge. BPSW aids in battery health management and predicting remaining useful life.
As LIB degradation alters the internal system parameters, reflected as trajectory warping in the reconstructed PS, the BPSW algorithm captures these changes to monitor battery degradation.
Experimental validation demonstrates that the BPSW algorithm can use battery cycle discharge voltage signals to track battery aging. Moreover, the HIs extracted by the BPSW algorithm have a strong linear correlation with battery capacity.
