A Model-Based Virtual Sensor for Condition Monitoring of Li-Ion Batteries in Cyber-Physical Vehicle Systems

OCV estimations with a semiphysical fuzzy model and Xu et al.’s method. The fitting is less accurate for charges below 8 Ah (20% SoC) or over 40 Ah (89% SoC), and the extrapolation to charges over the sampled data is not as regular as semiphysical model.
