Originální abstrakt

This work presents a digital-twin framework for second-life nickel–manganese–cobalt (NMC) Li-ion pouch cells that fuses physics-based and data-driven modeling. A thermal model captures temperature dynamics, while HPPC-derived measurements inform a semi-empirical equivalent-circuit model of the electrical behavior. Both are reduced to a computationally efficient reduced-order model for real-time use. The twin interfaces with hardware to stream voltage, current, and temperature, enabling continuous health monitoring and embedded safety actions, including grid disconnection to mitigate thermal runaway. Targeting cells with 20–30% capacity fade, the system detects anomalies, forecasts degradation trends, and supports predictive maintenance, improving operational reliability and extending usable lifetime in stationary second-life applications.
