Battery degradation

SOH estimate by age, mileage and usage

Usage

Car age, years

Mileage, k km

DC charging share, %

Climate

Typical modern EV degradation: 2–3% in year one (calibration), then ~1–2%/yr. Accelerators: frequent 100% DC fast-charging, storage at 100%/0%, heat. LFP batteries degrade slower than NMC. Warranty is usually 8 yr/160k km at SOH>70%. When buying used — ask for a LeafSpy/diag scan or a real-world range test.
