Notice of Request for Information (RFI) on Medium- and Heavy-Duty 
Electric Charging Technologies and Infrastructure Needs

AGENCY: Federal Highway Administration (FHWA), Department of 
Transportation (DOT).

ACTION: Notice; request for information (RFI).

-----------------------------------------------------------------------

SUMMARY: The FHWA, along with the Joint Office of Energy and 
Transportation (Joint Office), invites public comment on this request 
for information (RFI) regarding the Medium- and Heavy-Duty Electric 
Charging Technologies and Infrastructure Needs. This RFI seeks input in 
four areas to support medium and heavy-duty (MHD) battery electric 
vehicles (EV) (DOT vehicle classes 4 through 8) including: unique EV 
charger and station needs; vehicle charging patterns; MHD EV charger 
technology and standardization; and workforce, supply chain, and 
manufacturing to support charging of MHD battery EVs. The goal is to 
inform appropriate future Federal Government activities to support the 
development and deployment of EV chargers to support the anticipated 
needs of MHD EV original equipment manufacturers, fleet operators, 
drivers, charging station operators, and electric utilities. Comments 
should also address how to balance advances in technology with the need 
to expeditiously build out the national EV charging infrastructure, 
including support for MHD segments.

Background

    Vehicle manufacturers and operators are deploying MHD EVs at an 
increasing rate with a recent report citing the availability of over 
160 models and over 17,500 zero emission trucks in operation--a nearly 
10-fold increase from just 3 years ago.\1\ This trend in MHD EV 
adoption is driven by a combination of factors, including declining 
battery costs, improvements in vehicle performance and range, and 
growing recognition of the economic and environmental benefits 
associated with electrification.
---------------------------------------------------------------------------

    \1\ https://calstart.org/wp-content/uploads/2024/01/ZIO-ZET-2024_010924_Final.pdf.
---------------------------------------------------------------------------

    The regulatory landscape governing MHD EVs (DOT vehicle classes 4 
through 8) is evolving rapidly as well, driven in part by imperatives 
to reduce greenhouse gas emissions and criteria pollutants. Examples of 
such regulations include performance-based emission standards by the 
U.S. Environmental Protection Agency \2\ and the Advanced Clean Trucks 
rule through the California Air Resources Board,\3\ which other States 
may elect to adopt consistent with Section 177 of the Clean Air Act (42 
U.S.C. 7507).

---------------------------------------------------------------------------

[[Page 74357]]

    Fleet operators, cognizant of the long-term sustainability and cost 
advantages offered by electric propulsion, are increasingly embracing 
EVs as viable alternatives to conventional diesel-powered vehicles. The 
momentum toward electrification is further propelled by corporate 
sustainability goals, regulatory compliance pressures, and the 
emergence of innovative business models that prioritize operational 
efficiency and environmental stewardship.
    Increased adoption by fleets, the need to address the climate 
crisis, and the compelling total cost of EV ownership create a well-
timed backdrop for federal investments in the Bipartisan Infrastructure 
Law \4\ and the Inflation Reduction Act.\5\ These investments will 
support the buildout of the electrical generation, distribution, and 
charging network needed to provide clean, affordable, and reliable 
energy to a sector that accounts for 23 percent of transportation 
emissions despite accounting for only five percent of vehicles on the 
road.\6\ These investments will help meet U.S. federal goals of 100 
percent new zero-emission truck and bus sales by 2040, with an interim 
goal of 30 percent new zero-emission vehicle sales by 2030.\7\

---------------------------------------------------------------------------

    Stakeholders across the public and private sectors are mobilizing 
efforts to accelerate the expansion of charging infrastructure 
networks, enhance interoperability standards, and facilitate strategic 
investments in key infrastructure corridors. For example, the Joint 
Office of Energy and Transportation, in collaboration with the U.S. 
Department of Energy, Department of Transportation, and the 
Environmental Protection Agency, released in March of 2024 an all-of 
government National Zero-Emission Freight Corridor Strategy.\8\ The 
Strategy provides a phased approach to prioritizing planning, 
investment and deployment of MHD vehicle charging and hydrogen 
refueling infrastructure within freight hubs and along corridors to 
realize a complete zero-emission freight network by 2040. The privately 
led Powering America's Commercial Transportation Coalition \9\ (PACT) 
brings together vehicle and infrastructure manufacturers, fleets, 
utilities and other key stakeholders to collaborate on solutions to 
accelerate the pace of transportation electrification for MHD EVs. By 
proactively addressing the need for robust charging infrastructure, 
stakeholders can catalyze the transition to a cleaner, more sustainable 
transportation ecosystem, while positioning the industry for long-term 
success in an increasingly electrified future.
---------------------------------------------------------------------------

    \8\ https://driveelectric.gov/files/zef-corridor-strategy.pdf.
    \9\ https://www.pactcoalition.org/.
---------------------------------------------------------------------------

    The charging requirements for MHD EVs vary widely, reflecting the 
diverse operational profiles and energy demands within this sector.\10\ 
This spectrum ranges from vehicles engaged in on-demand operations with 
structured schedules, such as urban delivery trucks and transit buses, 
to inter-city and regional transit vehicles, like coaches and tractor 
trailers that cover longer distances between urban centers. In 
addition, fleet operators can often use vehicles to meet multiple use 
cases and duty cycles (e.g., municipal sanitation trucks that double as 
snowplows in the winter months). Shorter haul vehicles can often use 
centralized charging depots with the opportunity for lower power 
charging. At the other end of the spectrum, long-haul and over-the-road 
applications, exemplified by heavy-duty trucks engaged in Interstate 
freight transportation, may require ultra-fast charging capabilities to 
allow trucks to quickly get back on the road. These vehicles operate 
continuously for extended periods, necessitating strategically located 
charging stations along major transportation corridors to facilitate 
rapid turnaround times or provide parking facilities with charging. 
Developing a charging infrastructure ecosystem entails addressing this 
spectrum of use cases comprehensively, ensuring that solutions are 
scalable, adaptable, and aligned with the evolving needs of the 
transportation industry.

Purpose

    This RFI seeks input in four areas to support charging of MHD EVs: 
(1) unique EV charger and station needs; (2) vehicle charging patterns; 
(3) MHD EV charger technology and standardization; and (4) workforce, 
supply chain, and manufacturing. The information received from this RFI 
will inform government activities to support the development and 
deployment of EV chargers to meet the anticipated needs of MHD EV 
original equipment manufacturers, fleet operators, drivers, charging 
station operators, and electric utilities. This RFI also seeks to 
understand MHD EV charging as a whole, rather than through 
transportation and electricity-specific lenses. Increasing 
understanding and awareness across all relevant sectors is key to 
ensuring that electric MHD vehicle fleet operators and charging 
networks:
    <bullet> Support a modern electric grid and create widespread 
benefits for fleet operators, communities, and all ratepayers; and
    <bullet> Are served by energy regulatory environments and public 
policies that reflect the wide variety of vocational needs, use cases, 
and duty cycles for electric medium and heavy-duty buses and trucks.
    Though hydrogen refueling can provide a zero-emission fuel option 
for commercial MHD vehicles, this RFI only seeks information on 
electric charging considerations for MHD EVs.
