That's something we're considering, but no it's not an easy thing to add. Our site is designed to help you calculate Miles/Gallon. A gallon is a liquid fuel with a certain volume. So it's fairly easy to translate between other liquid fuel measurements such as litres. But how does a kilowatt per hour translate into a litre? I'm not sure there's an obvious answer or an accepted standard of translation. If there is, please let me know.
Without being able to come up with MPG or L/100km for a vehicle, how do we compare it with other vehicles? How are other services like ours tackling this problem? Is the EPA tracking electric vehicles in the same way? I don't think these are easy questions to answer.
Personally I think MPG or L for an electric vehicle is meaningless and confusing, so I hope you don't do it that way
A gallon of fuel has a certain volume but the density of it changes with temperature, and the energy it contains varies according to the refinery processes and summer/winter blends, addition of biofuels, whether it's petrol or diesel or LPG, etc etc. So it's actually a pretty unprecise measure.
A kWh is a kWh, a precise, unvarying unit of energy. You'd actually be better off converting all the liquid fuel quantities into average kWh values (a litre of petrol is about somewhere around 11kWh IIRC).
Anyway, I don't see the issue with reporting kWh per mile - most EVs do between 0.2 and 0.5 (or 200 and 500Wh/mile)
Anyway, I don't see the issue with reporting kWh per mile...
Yeah, I'm sorry the site isn't designed to report that. We're set up to share and compare MPG. kWh/mile doesn't fit in with that scheme, and we're not going to completely reshape the site for a couple of vehicles. At our current moment in history people use MPG to compare the fuel economy of vehicles, so we're going to stick with that.
