Projects Funded by the Joint Office

The Joint Office of Energy and Transportation (Joint Office) is funding projects across the United States whose outcomes aim to improve and expand zero-emission and electric vehicle (EV) charging infrastructure for all Americans.

As the nation experiences the biggest transportation transformation in a century, more research and understanding are essential to support a convenient, accessible, equitable, and reliable charging experience. The Joint Office is dedicated to partnering with National Laboratories, including the National Renewable Energy Laboratory (NREL), Argonne National Laboratory, Idaho National Laboratory, Lawrence Berkeley National Laboratory, Pacific Northwest National Laboratory, Sandia National Laboratory, and Volpe National Transportation Systems Center to ensure a successful transition to a clean transportation system through projects informing the advancement of such technologies across the United States.

The electric vehicle grid integration (EVGI) team at NREL performs evaluations of medium- and heavy-duty electric vehicles to support the development of EV connectors.

Ongoing Projects

Below are descriptions and resources for ongoing Joint Office funded projects ranging from soft costs related to building infrastructure to equity best practices.

The BILD-AQ Framework is creating a tool to estimate location-specific benefits of Bipartisan Infrastructure Law funded EV infrastructure deployment. The model can estimate impacts on EV adoption, EV utilization, and air pollutant emissions from both the electric grid and on-road vehicle travel. These emissions are used to estimate changes in PM2.5 concentration and premature mortality. The tool is able to estimate national, or state-by-state, impacts of EV infrastructure deployment. This project began in April 2023, with tool documentation and example analysis results expected in early 2025.

CalderaCast is a website tool that provides electrical-load and utilization forecasts for potential future EV charging station locations based on the types of chargers and the expected EV adoption. The tool relies on traffic volume data along designated Alternative Fuel Corridors (AFCs) in the United States and is most accurate for locations along these corridors. CalderaCast can be used to help plan for public charging station projects, including National Electric Vehicle Infrastructure (NEVI) charging station locations along AFCs.

This tool is designed to aid potential funding applicants, local distribution utilities, state agencies, and other critical stakeholders in their efforts to plan and prepare for the installation of new charging stations. It requires basic information about charging station location, the types of chargers to be installed, and a date of operation (to account for future increased EV adoption). CalderaCast will then compute a forecast of the frequency of vehicles stopping to charge at the proposed station, and the expected electrical load on the power grid. This capability allows interested parties to estimate the appropriate size, scope, and supply equipment types for a proposed charging station to best meet the need of the proposed location. As of late 2024, CalderaCast is nearing completion and will soon be available to the public.

The National Charging Experience (ChargeX) Consortium convenes industry, national labs, consumer advocates, and other stakeholders to measure and improve public charging reliability in North America by 2025. Multiple task forces are developing technical solutions and recommended practices for improving charging and EV communications; hardware design, testing and diagnostics; and performance measurement. These solutions will be implemented by industry and codified into standards to improve the EV charging customer experience. The project began in June 2023, with an estimated completion date of June 2025.

Project Resource

Pacific Northwest National Laboratory (PNNL) and Idaho National Laboratory completed a project to improve cybersecurity risk mitigations within EV charging systems, and further the adoption of EVs across America. This effort resulted in a national approach for EV Charging Protocols and Security Provisions for ISO 15118, OCPP, and OCPI, which can be found in the National Electric Vehicle Infrastructure Standards and Requirements (23 CFR 680) published in March 2023. PNNL also released Sample Cybersecurity Procurement Language Clauses for Request For Proposals and Electric Vehicle Service Provider Contracts in April 2023. This guidance has been used by NEVI funding recipients to develop robust contracts to last throughout their lifecycle. PNNL continues to work with the NASEO-AASHTO subcommittee on cybersecurity to transition this guidance to federal electric vehicle charging infrastructure grant recipients.

This project delved into the various business model archetypes in the EV infrastructure charging space, the barriers in manufacturing and deployment of EV infrastructure, and how policies at the local, state, and federal level can be used to enhance the visibility of these models. It helps stakeholders understand the drivers and sensitivities of each charging model, guiding state government and others in their electrification plans. The project ran from August 2023 to November 2023.

This project is analyzing the cybersecurity implications of the EV charging system standards required by the National Electric Vehicle Infrastructure (NEVI) Formula Program. The work aims to allow both government and industry to be aware of, and quickly begin to address, foundational public key infrastructure (PKI), cybersecurity, and other related limitations inherent to the NEVI buildout. The project began in September 2023 with simulation work ongoing.

Argonne National Lab developed and is maintaining an internal EV dashboard to show regional and national trends in Plug-in EV adoption, technology evolution, EV/battery supply chain, investments, fuel savings, and petroleum reduction. It aims to provide facts about EVs and EV batteries for use by the White House, the U.S. Departments of Transportation and Energy, and the Joint Office. The project launched in October 2022, with a project completion date of September 2024.
