SOC Estimation of Lithium-Ion Batteries Based on Multi-Frequency Impedance Feature Point Extraction and Whale-Optimized Backpropagation Neural Network

Accurate estimation of the state of charge (SOC) of lithium-ion batteries is essential for energy management and safety control in battery management systems (BMSs). Conventional methods, such as Coulomb counting and open-circuit voltage methods, are constrained by error accumulation and slow response. This study propo...
