Implementation of Unscented Kalman Filter-Based Online State-of-Charge Estimation in LiFePO4 Battery-Powered Electric Vehicle Applications

This paper proposes an online state-of-charge (SoC) estimation method based on a 2nd-order RC model. The open circuit voltage (OCV) of the battery is calculated through two adaptive filtering stage, which is then used to determine the SoC via a dynamic OCV-SoC curve. In the first stage a variable st...
