ABSTRACT Battery Management System (BMS) requires an indefinite accurate model. With an aging model, the lifetime of a battery can be precisely predicted with respect to the State- of-Charge (SoC) of a battery. The mathematical model in terms of state variables involving 

Integrating State of Charge (SOC) Dependent Material Properties Into Li-Ion Battery Failure Modeling
