THE SOH AND THE SOC ASSESSMENT OF NCR18650 PANASONIC CYLINDRICAL BATTERY THROUGH THE ENTROPYMETRY

Abstract

As the demand for the li-ion batteries increases in various areas, the precise and reliable assessment of the state of health (SOH) and the state of charge (SOC) of the battery become more important in the battery management system (BMS). The main goal of this research work is to create the model for the assessment of the SOH and SOC of the NCR18650 PANASONIC cylindrical battery based on thermodynamics parameters such as, enthalpy and entropy.
