Battery Pack Capacity
The chart below shows the reported battery capacity versus miles driven for each of the vehicles in the Model S survey. Battery capacity is measured by doing a full charge and reading the "rated range" from the car, which is the estimated range if the car were driven in the same conditions and parameters as used for the vehicle's official range rating. Cars in the US and Canada are rated using the EPA standard. Other countries use the NEDC standard. Values in the chart are adjusted to be equivalent to the EPA standard and reports in kilometers are converted to miles.
The vehicles are grouped by their battery pack size. Note that different models with the same battery pack size may have slightly different EPA ratings for their full nominal range (dual vs. single drive and performance versions).
Trend lines are shown for models with sufficient data available. This gives an idea of what the data suggests is the average Model S experience. Note that the data includes some vehicles which have had battery pack replacements (see the chart below) which may have extended their capacity lifetime, so a more careful analysis is required to extract the best model for battery pack longevity.
