EV
Depth of Discharge (DoD)
How deeply an EV battery is regularly discharged — a key driver of degradation.
Routinely running an EV from 100% to 0% accelerates degradation. Best-practice is the 20–80% window for daily use, with occasional full charges for long trips. A used EV that's spent its life on DC fast chargers and run flat regularly will show worse SoH than one charged AC at home.
