This report quantifies the gap in charging infrastructure to power more than 3 million expected electric vehicles by 2025. Based on the expected growth across the 100 most populous U.S. metropolitan areas, we estimate the amount of charging of various types that will be needed to power these vehicles.
The figure illustrates the deployment of public and workplace charging infrastructure through 2017 as a percentage of what will be needed by 2025 across the 100 most populous U.S. metropolitan areas (the 50 most populous are labeled). Shades of red indicate that less than 50% of the needed charging has been installed through the end of 2017, while blues indicate that more than 50% of charging needed in 2025 was in place by 2017. Of the 100 areas, 88 had less than half of the total needed charging infrastructure in place, based on their expected electric vehicle growth.
The widespread distribution of electricity offers the potential for highly convenient charging of electric vehicles if the right ecosystem of charging outlets is matched to complex driver charging behavior. While the vast majority of electric vehicle charging is and will continue to be at home, public and workplace charging options allow drivers to take advantage of the times and places where electric vehicles are parked. Our analysis leads us to three high-level conclusions.
