Electric Vehicles: Charging Infrastructure

Charging Infrastructure

Developing Infrastructure to Charge Plug-In Electric Vehicles, Alternative Fuels Data Center, U.S. Department of Energy (DOE).

This resource page summarizes charging terminology and charging equipment, with links to additional resources throughout.


Alternative Fuel Corridors, Federal Highway Administration (FHWA), updated April 2021.

The national network of alternative fuel corridors identifies alternative fueling and charging infrastructure along National Highway System corridors. Established through the Fixing America's Surface Transportation (FAST) Act of 2015, the network facilitates strategic deployment of electric vehicle charging infrastructure across the country. For the fifth round of corridor designations, announced in 2020, a highway segment must have public direct current (DC) fast charging sites with both connector types at least every 50 miles, no more than 5 miles off the highway.


Federal Funding Is Available for Electric Vehicle Charging Infrastructure on the National Highway System, FHWA, April 2022.

This 16-page brochure outlines funding and financing programs available to help states, tribes, metropolitan planning organizations and others build out electric vehicle chargers along the National Highway System.   

 


Alternative Fuel Toolkit, FHWA and Oregon Department of Transportation, 2018.

Developed through a multistate pooled fund study led by Oregon DOT, this resource includes fact sheets, maps and five online toolkits developed in conjunction with a series of workshops held around the nation from 2015 to 2018. Toolkits include:

Pooled fund research brief, Caltrans, 2019.


Best Practices for Electric Vehicle Supply Equipment Installations in the National Parks, National Renewable Energy Laboratory (NREL), December 2019.

This report captures challenges, lessons learned, and best practices from recent National Parks Service (NPS) installations of electric vehicle supply equipment for light-duty plug-in electric vehicles. Based on interviews with NPS employees and project stakeholders, the report summarizes notable takeaways and makes recommendations to help ensure the success of future charging installation projects. 


Research in Progress

NCHRP Synthesis: Strategies and Programs for Electric Vehicle ChargingNational Cooperative Highway Research Program (NCHRP), start date: April 2021.

This synthesis will document current strategies and practices in use by state DOTs to facilitate and coordinate the provision and operation of EV charging facilities. The synthesis will also include current plans to address the future maturity of EV charging, such as preparation for medium- and heavy-duty electrification. Topics include practices for EV charging infrastructure deployment, delineation of operating and maintenance responsibilities, public/private partnerships, procurement and contracting, and pricing strategies; planning and prioritizing charging infrastructure; working with utilities; navigating funding complexities; evaluating program effectiveness; providing guidance or technical assistance to local governments; and policies for EV charging stations along state-owned roadways or in public rights of way.

California

Quantifying the Tangible Value of Public Electric Vehicle Charging Infrastructure, California Energy Commission and National Renewable Energy Laboratory, July 2020.

This report helps inform decisions on investing in public charging infrastructure by estimating consumers’ willingness to pay for access to it. Researchers developed a set of three functions that can be used to calculate the willingness to pay for public charging infrastructure as a function of vehicle range, existing charging infrastructure, energy prices, income and annual vehicle travel. 


Colorado

Colorado Energy Office: EV Fast Charging Corridors Grant Program, case study, Alternative Fuels Data Center, U.S. Department of Energy (DOE), June 2019.

This case study details Colorado's experience with setting up a grant program to fund the installation of direct current (DC) fast charging stations along main travel corridors in the state.


Delaware

Expanding the UC Davis GIS Electric Vehicle Planning Toolbox Beyond California: The Delaware Valley Regional Planning Commission Case Study, National Center for Sustainable Transportation, July 2021.

This project created an ArcGIS toolkit that allows users to project where EV owners will live, work and charge. Three modules focus on market analysis, workplace charging and home charging.


Pennsylvania

Electric Vehicle Planning GIS Toolkit for Greater Philadelphia, National Center for Sustainable Transportation, October 2019.

At the census block group level, this toolkit predicts the spatial distribution of plug-in electric vehicles (PEVs) and the workplace charging demand of those vehicles.


Tennessee

Fast Charge TN Network, Tennessee Department of Environment and Conservation (TDEC).

The TDEC and the Tennessee Valley Authority are partnering to develop a statewide electric vehicle fast charging network to power the growth of EVs across Tennessee and reduce barriers to transportation electrification.

Texas

Technology Utilization Plan, Texas Department of Transportation, June 2021.

As the culmination of a three-stage effort to identify and prioritize promising transportation technologies, this plan provides information on lessons learned from technology deployments in other agencies and recommendations for implementation in Texas. Electric vehicles are addressed on page 26 of the plan (page 36 of the PDF). Case studies include:

  • Dallas Area Rapid Transit's deployment of seven electric buses.
  • Use of EV municipal fleet vehicles in Denton, Texas.
  • San Francisco Municipal Transportation Agency's partnership with ChargePoint to support the agency's transition to an electric bus fleet.
