Battery Cycle Degradation Estimator

Estimate battery capacity fade based on cycles, load, temperature and depth of discharge. This is a heuristic tool — calibrate with manufacturer data for more accuracy.

Tip: calibrate kBase to a datasheet point (e.g., "1000 cycles to 80% at 25°C and 80% DoD").

Model notes:

Simplified empirical model for planning; not a substitute for lab data.
Temperature and deeper DoD accelerate degradation.
Calibrate with manufacturer cycle-life curves when available.
