As of April 2014, there were 630 plug-in passenger cars in the state, a small but quickly growing fraction of the overall fleet. Approximately 1/3 of these vehicles were registered in Chittenden County. EV owners are generally expected to charge their vehicles at home overnight, but away-from-home charging will be needed to allow longer trips and increase the suitability of EVs for a variety of users. Availability of public charging affects consumer willingness to consider EV purchases, particularly in the case of all electric vehicles which do not use gasoline to extend range.
Priority locations for public EVCEs include areas with concentrations of retail, recreation, and public administration services. These destinations commonly have parking durations long enough to allow time for appreciable charging. This technical report examines a series of factors related to potential demand for public charging locations and provides a listing of suggested Chittenden County locations to further explore EV charging with property owners.
