How to use the EV Battery Health & Degradation Estimator
The Formula
Calendar aging, cumulative miles, and frequent DC fast charging all contribute to capacity fade. Thermal management and chemistry vary widely by model.
Practical Example
This is a simplified model for curiosity—not a diagnostic. For warranty or resale, use dealer scans or OBD SoH reports.
