Thermal Load Analyzer
Estimate per-cell and pack heat load under continuous, pulse, and WLTC-like duty cycles.
How this works
P_heat = I^2 * R, Delta T ~= Q * t / (m * c_p)
Methodology
Based on Joule heating: P_heat = I² × R. Temperature rise uses lumped thermal capacity: ΔT = Q / (m × c_p). Duty cycles model continuous (1C), pulse (3C 10s), and WLTC-derived current profiles.
