SOC Estimation of Lithium Iron Phosphate Battery Based on Kalman Filtering Algorithm

In order to improve the estimation accuracy of the state of charge (SOC) of electric vehicle, a second-order RC equivalent circuit model considering the battery capacity time-variation is proposed. Combining the nonlinear characteristics of lithium iron phosphate battery and the second- order RC equ...
