According to a US Energy Department study concocted with charging station maker Ecotality, plug-in vehicle owners are, on average, driving more than gas-powered vehicle owners are driving their cars. Plug-in vehicle drivers are also getting more comfortable charging those vehicles outside of their homes.
Chevy Volt drivers are, on average, logging over 41 miles per day in their cars. Nissan Leaf owners are logging 30 miles per day in their cars. Compare this to the 28.9 miles a day for the average vehicle powered by an internal combustion engine.
Of course, this has something to do with plug-in vehicles being purchased as commuter vehicles because the more someone used to drive in an ICE vehicle, the more they can save with a plug-in vehicle.
Plug-in vehicle drivers charged their vehicles away from home about 33% of the time in the third quarter of 2012, compared to only about 22% of the time earlier in the year.
