Nowadays, lithium-ion is among the most used chemistry for batteries and shows an increasing market growth rate. However, to reduce failure or safety risks, battery State-of-Charge (SoC) must be accurately monitored predicted by a suitable Battery Management System (BMS). Artificial Intelligence (AI) techniques have been extensively applied this field with good results. Typically, AIs are trained on dynamic profile data, emulating charging discharging cycles related application under test....
