The open circuit voltage (OCV) is of essential importance for accurate estimation of the state of charge (SoC) in lithium-ion battery (LiB). The OCV-SoC relationship is typically predetermined by fitting offline OCV data. Commonly used two OCV tests are compared in few literatures. Moreover, they only focus on the middle SoC region (i.e., 20% and 90%) of LiNiMnCoO2 (NMC) LiBs, the performances of...
In order to ensure the safety and reliability of electric vehicles (EVs), the accurate center of gravity (CG) position estimation is of great significance. In this study, a novel approach based on combined H∞–extended Kalman filter (H∞–EKF) is proposed. Utilizing the characteristics of the wheel torque controlled independently, the estimation method only requires the longitudinal stimulus of vehicles...
