Entropy-driven online open circuit voltage identification for precise state estimation in lithium-ion batteries

Summary: The open circuit voltage (OCV)—state of charge (SOC) curve of lithium-ion batteries is affected by battery inconsistency and degradation. Compared to lab methods, which are time-consuming, using operation data of electric vehicles (EVs) to identify OCV-SOC curve online attracts increasing a...
