100 miles doesn't sound like enough, how will this vehicle be used?
The Nissan Leaf, and any BEV, is intended to operate as a normal vehicle. While 100 miles may not be sufficient for long trips, 100 miles is much more than most people drive in any given day. The 2009 National Household Travel Survey results show that the average vehicle drives 25 miles a day. If you're worried about running out of juice in an EV, consider the purchase of a PHEV. With consistent charging, a number of gasoline starts and engine warm-ups can be eliminated. There are of course financial benefits as well, with increased charging there will be less of a need to visit the gas station. Additionally, the DOE is investing in installing public charging infrastructure.
Those who have purchased electric vehicles can contact their utility company for information on how to maximize the benefits, including when and how to charge.
