State-of-Charge Estimation of Lithium-Ion Batteries in Parallel for Electric Vehicles Using Improved Square Root Unscented Kalman Filter

An accurate state of charge (SOC) estimation is crucial for battery applications. Traditional model-based methods have difficulty addressing parameter mismatches and measurement errors, whereas the Kalman filter method faces challenges in handling non-Gaussian noise. In this paper, an improved squar...
