ECOtality North America, OnStar, and the Idaho National Laboratory have partnered to collect and analyze electronic data from Chevrolet Volts enrolled in The EV Project, which is a large-scale plug-in electric vehicle infrastructure demonstration being conducted in 21 metropolitan areas across the United States. This paper presents results of an early analysis of these data. The data set analyzed came from 923 privately owned vehicles, which logged over 4.7 million driving miles from October 2011 to October 2012. These data are used to identify the potential of electric vehicle (EV) mode driving, based on driver and charging behavior. Driving and charging behavior is quantified with metrics such as daily vehicle miles traveled, number of charging events performed per day, and distance driven between consecutive charging events. Drivers averaged 40.7 miles per day, with a median of 31.6 miles per day.

In 2010, a large-scale plug-in electric vehicle (PEV) infrastructure demonstration was launched to deploy an unprecedented number of PEVs and charging infrastructure. This demonstration, called The EV Project, is funded by the U.S. Department of Energy and led by ECOtality North America. ECOtality has partnered with Nissan North America and General Motors to deploy up to 8,300 Nissan LEAF™ battery electric vehicles and Chevrolet Volt extended-range electric vehicles, along with approximately 14,000 AC Level 2 and DC fast-charging units in 18 metropolitan areas across the United States. ECOtality and the Idaho National Laboratory partnered to collect and analyze electronic data from EV Project vehicles and charging units. An early analysis of data from Nissan LEAFs enrolled in The EV Project was performed. The data set analyzed came from 2,903 privately owned vehicles, which logged over 10 million driving miles in 2011.
