A coupled electrochemical–thermal battery simulator — equivalent circuit modeling, SOC/SOH estimation, CC-CV charge curves, and degradation analysis across 6+ cell chemistries. In your browser, no install.
Every model is grounded in peer-validated electrochemistry — OCV lookup tables, Arrhenius degradation rates, and coupled thermal dynamics.
I²R₀ + exothermic reaction heat. Convective cooling boundary conditions. Temperature feeds back into ECM parameters.OCV curves, capacity, and thermal parameters sourced from experimental datasets — not synthetic averages.
Degradation and thermal behavior come from the same equations used in battery management system design — not a linear approximation.
k as a function of temperature T. This is why a pack running 15°C hotter can degrade 2-3× faster — the exponential term dominates, not a linear derating.
That same thermal model couples to Joule heating from internal resistance — the dominant heat source during fast charging and high-current discharge:
