A Hierarchical Multi-Timescale Method with Aging-Aware Capacity Correction for Low-Temperature State-of-Charge Estimation of Lithium-Ion Batteries

Accurate state-of-charge (SOC) estimation is essential for range prediction, power allocation, and operational safety in electric vehicles. Low-temperature operation introduces coupled effects of capacity degradation and polarization dynamics, which challenge conventional fixed-capacity models and single-timescale esti...
