To develop a predictive lithium-ion battery degradation model based on crack propagation mechanics for variable use in electric vehicles and vehicle-to-grid systems.
Derived a mechanical battery aging formulation based on crack propagation theory to describe exponential degradation as a function of stress parameters such as depth of discharge.
Integrated the stress-based aging formulation with an empirical equivalent circuit model to determine state of charge, charge/discharge rates, and temperature dependencies under arbitrary cycling histories.
Demonstrates that battery degradation exhibits an exponential dependence on stress metrics calculated from arbitrary, mixed charge and discharge profiles.
Enables cycle life predictions across diverse operating temperatures and charging rates using minimal cell-specific parameter fitting.
