What it supports
Fleet-average battery health decline on the order of 1.5-2.5 %/yr; heavy DC fast-charging use and hot climates associated with faster decline.
Limitations
Aggregate telematics; BMS-reported SOH; mixed models; methodology not peer-reviewed; figures summarised from public statements.
Conclusions that should NOT be drawn
Predictions for an individual vehicle; causal attribution of mechanisms.
