Has anyone made an effort to separate out speed, AC and heating, temperature and age as factors in range? I find it a little frustrating that people seem to want to produce a single number (73, 100, etc.) when range clearly depends on several factors. Ideally it would be nice to have a series of ranges or distance per kW for a number of common speeds with AC and heating off, and then some kW/hour at various AC/heating settings.
My commute is 48km/30miles each way, which is well short of even the 73mile range from the EPA, but 41km/25miles of it, each way, is highway driving at 100kph/62mph. The "70 miles at a steady 55 mph on the highway on a hot 95-degree day with the air conditioning on" example from Nissan says I would probably be ok in spring, summer, and fall, although not with a very large margin. On a cold day in winter (say 20 degrees below freezing) it seems I might not make it without a recharge at work.
It's hard to know from the various figures I've seen whether I'll be able to commute that comfortably or whether I need to arrange charging at work, or, failing the "double the range you think you need" rule I should wait for the next generation of EV. Any thoughts?
Has anyone figured out the relative energy costs of the various factors, even roughly?
