Charging Infrastructure Required to Support U.S. Electric Vehicle Deployment: A Cost Estimate through 2025

Although U.S. policies encourage adoption of plug-in electric vehicles (PEVs), they make up a small share (less than one percent) of U.S. vehicle sales. There are many challenges to increasing PEV market share-one of which is the lack of public charging infrastructure, which may reduce consumer acceptance and confidence in PEVs. This paper highlights issues surrounding new charging infrastructure, documents existing infrastructure, and discusses the role of policy in supporting installation of new infrastructure. Eight states have set a goal of having 3.3 million registered Zero Emissions Vehicles (ZEVs)-most of which will be PEVs-in operation by 2025; this target is used to estimate the cost of expanding infrastructure in those states over the next decade.
