State of charge (SoC) estimation is vital for battery management systems in electric vehicles (EVs). Lithium-iron phosphate (LFP) batteries, known for their power density, cycle life, and thermal stability, present unique challenges due to flat voltage and hysteresis effects. This study employs a pu...
