Estimation of State of Charge for Lithium-Ion Battery Based on Finite Difference Extended Kalman Filter

An accurate estimation of the state of charge (SOC) of the battery is of great significance for safe and efficient energy utilization of electric vehicles. Given the nonlinear dynamic system of the lithium-ion battery, the parameters of the second-order RC equivalent circuit model were calibrated an...
