IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishA general state of charge (SOC) and state of health (SOH) evaluation algorithm is described and implemented in this paper for an electrochemical cell that exhibits voltage hysteresis. The algorithm is based on evaluating the parameters of an equivalent electric circuit model of the cell and then using an extended Kalman filter (EKF) for runtime evaluation of the SOC and SOH using the terminal current and voltage measurements as inputs. The behaviour of the model algorithm is validated to examine its effectiveness and robustness for a lithium iron phosphate cell
