The ANSI Electric Vehicles Standards Panel (EVSP) is a cross-sector coordinating body whose objective is to foster coordination and collaboration on standardization matters among public- and private-sector stakeholders to enable the safe, mass deployment of electric vehicles (EVs) and associated infrastructure in the United States with international coordination, adaptability, and engagement. The ANSI EVSP does not develop standards; rather, it serves as a forum for facilitating coordination among standards developing organizations (SDOs) and others.

On June 15, 2023, ANSI announced the publication of the Roadmap of Standards and Codes for Electric Vehicles at Scale developed by the EVSP. The roadmap’s primary focus is on light-duty, on-road plug-in EVs that are recharged via a connection to the electrical grid, as well as the supporting charging infrastructure needed to power them. Medium and heavy-duty EVs are also covered, as is wireless charging. A total of 37 standardization gaps are identified with corresponding recommendations across the topical areas of vehicle systems, charging infrastructure, grid integration, and cybersecurity. It is hoped that the roadmap will see broad adoption by the user community and will facilitate a more coherent and coordinated approach to the future development of standards for EVs.

Some 80 individuals from 130 public- and private-sector organizations supported the roadmap’s development, including U.S. federal government agencies and national laboratories, standards developing organizations (SDOs), industry, academia, and others. The document represents the culmination of the EVSP’s work over the past year to identify key safety, performance, and interoperability issues for EVs and charging infrastructure, relevant published standards and standards in development, and to assess gaps. A “gap” means no published standard, code, regulation, policy, etc. exists that covers the particular issue in question.

Of the 37 gaps, 14 gaps/recommendations are identified as high priority, 20 as medium priority, and 3 as low priority. In 23 cases, additional pre-standardization research and development (R&D) is needed. The roadmap also provides prioritized timeframes for when standards work should occur, and identifies SDOs or others that may be able to develop the standards or perform the R&D. It is envisioned that a mechanism will be established to assess progress to implement the roadmap’s recommendations. The target audience for the roadmap includes vehicle manufacturers; entities that will be installing and operating charging infrastructure; SDOs; U.S. federal, state, and municipal government agencies; electric utilities; and others.

The impetus to develop the roadmap came about following a June 2021 lab call funding opportunity announcement issued by the U.S. Department of Energy (DOE) Office of Energy Efficiency & Renewable Energy (EERE) Vehicle Technologies Office (VTO), to help advance the Biden Administration’s goal for a clean energy future. The lab call’s codes and standards pillar sought to “identify and address challenges and barriers to the integration of EVs@Scale charging with the grid created by uncoordinated development of codes and standards and the rapid advances in vehicle and charging technologies.” In response, the EVs@Scale lab consortium was formed with Argonne National Laboratory (ANL) having the lead for the codes and standards pillar supported by other national labs. The consortium reached out to ANSI, as administrator and coordinator of the U.S. private-sector voluntary standardization system, to facilitate developing a roadmap similar to earlier ones developed by the ANSI EVSP in the 2011-14 timeframe. The EVs@Scale effort supports funding initiatives associated with deploying a nationwide EV charging infrastructure, including the National Electric Vehicle Infrastructure (NEVI) Formula Program, which provides $5 billion in federal money to that end. As part of the Bipartisan Infrastructure Law, the Federal Highway Administration was directed to release a set of minimum standards and requirements for the implementation of the NEVI program. The NEVI Final Rule was issued on February 28, 2023, and appropriate references are included in the EVSP roadmap.


The EVSP provides a forum for the development of the public-private partnership needed to facilitate the large-scale introduction of electric vehicles into the market. Participation in the EVSP is open to EV stakeholders that have operations in the U.S. Participants include representatives of the automotive, electrotechnical and utilities industries, relevant trade associations, standards development and conformity assessment organizations, government agencies, and academia, providing a range of perspectives. ANSI membership is encouraged but is not a prerequisite and there is no fee to participate at this time.

To develop the roadmap, the EVSP established three working groups that typically held online meetings twice a month: WG1 on vehicle systems, WG2 on charging infrastructure, and WG3 on grid integration and cybersecurity. Since the roadmap has now been published, the working groups are not currently meeting.

As a general matter, ANSI undertakes to coordinate standardization activity for emerging technologies and national/global priorities on behalf of the community of interest with the expectation that those who benefit will provide funding to support the Institute’s engagement. Direct sponsorships include appropriate recognition benefits. All sponsorship revenue is directly applied to help offset the Institute’s costs of operating the activity.
