I'm trying to figure out which car I should take to El Dorado Hills from San Jose tomorrow. 308 miles round trip. multiplied by 1.3 means I need about 400 rated miles. I'll start tomorrow with 260, so that means I need to get about 140 from the charger. How long will I likely have to spend in Folsom to get from 60 rated miles to 200? thanks, Derek actually, let's say 60 to 220 to be safe.
