Many counties and cities in Florida are developing resilience plans to help them minimize damage from hurricanes and accelerate recovery. Fuel diversification can add to Florida’s transportation resilience because if the supply of one fuel gets disrupted during a hurricane, there is a good chance that the supplies of other fuels are still available. The Florida Alternative Transportation Fuel Resilience Plan aims to address these factors and create a strategy for how three alternative fuels (natural gas, propane, and electricity) can best be employed to improve transportation resilience in Florida. It does this through a combination of literature review and stakeholder engagement for best practices, vehicle technology recommendations, the creation of three tools (with descriptions and brief guides included), and charting how stakeholders coordinate to overcome these hurdles.

Review of Electric Vehicle Charger Cybersecurity Vulnerabilities, Potential Impacts, and Defenses Johnson, J.; Berg, T.; Anderson, B.; Wright, B. 5/26/2022 Journal Articles & Abstracts

Sandia National Laboratories, Albuquerque, New Mexico

Worldwide growth in electric vehicle use is prompting new installations of private and public electric vehicle supply equipment (EVSE). EVSE devices support the electrification of the transportation industry but also represent a cornerstone for power systems and transportation infrastructures. Cybersecurity researchers have recently identified several vulnerabilities that exist in EVSE devices, communications to electric vehicles (EVs), and upstream services, such as EVSE vendor cloud services, third party systems, and grid operators. The potential impact of attacks on these systems stretches from localized, relatively minor effects to long-term national disruptions. Fortunately, there is a strong and expanding collection of information technology and operational technology cybersecurity best practices that may be applied to the EVSE environment to secure this equipment. This paper summarizes publicly disclosed EVSE vulnerabilities, the impact of EV charger cyberattacks, and proposed security protections for EV charging technologies.

A Framework to Analyze the Requirements of a Multiport Megawatt-Level Charging Station for Heavy-Duty Electric Vehicles Mishra, P.; Miller, E.; Santhanagopalan, S.; Bennion, K.; Meintz, A. 5/21/2022 Reports

National Renewable Energy Laboratory, Golden, Colorado; Department of Energy, Washington, D.C.

Widespread adoption of heavy-duty (HD) electric vehicles (EVs) will soon necessitate the use of megawatt (MW)-scale charging stations to charge the high capacity HD EV battery packs. While higher throughput will maximize revenue-generating operations, at high rates of charging, the station design needs to anticipate possible station traffic, average and peak power demand, and charging/waiting time targets to meet. High-voltage direct current fast charging (DCFC) is an attractive candidate for MW-scale charging stations at the time of this study but there are no precedents for such station design. We present a modeling and data analysis framework to elucidate the dependencies of a MW-scale station operation on vehicle traffic data and station design parameters and how that impacts vehicle electrification. This framework integrates an agent-based charging station model with vehicle schedules obtained through real-world, long-haul vehicle telemetry data analysis to explore the station design and operation space. We present a case study showing the application of this framework to: (i) choose optimal locations for charging infrastructure to enable vehicle electrification, (ii) simulate vehicle charging behavior to create charge demand schedules for MW-scale charging locations, (iii) analyze power/energy requirements for these stations, and (iv) optimize station design and control to increase vehicle throughput. Real-world vehicle travel data is used to generate distributions of vehicle arrival time and state of the charge (SOC) for hypothetical MW-scale charging stations. Monte Carlo simulation is used to explore various design considerations associated with MW-scale charging stations and electric vehicle battery technologies.

Impacts of Increasing Electrification on State Fleet Operations and Charging Demand Booth,S.; Bennett, J.; Helm, M., Arnold, D.; Baker, B.; Clay, R.; Till, M.; Sears, T. 2/1/2022 Reports

Sawatch Labs, Denver, Colorado; National Renewable Energy Laboratory, Golden, Colorado

State fleets represent an enticing opportunity to explore the near-term feasibility of fleet electrification. In many instances, state fleet operations encompass a wide geographic area with fleet locations for many vehicles. Serving these wide areas will require a significant amount of energy and, in the case of electric vehicles (EVs), a significant level of charging power. The peak demand as a result of this charging demand is of interest for fleets, with impacts on both utility bills and installation costs ranking among some of the greatest concerns. The combination of a wide operational area and multiple fleet locations positions state fleets as ideal candidates to understand the impacts of vehicle charging on fleet operations. As the availability of electric drivetrains expands beyond light-duty sedans, fleets need to understand when it will be appropriate operationally and financially to start adding electric drivetrains to their fleets. Throughout this process, it will also be important to understand the charging implications of fleet electrification and the resulting impacts to facility electrical systems. To better understand these considerations, NREL contracted Sawatch Labs to analyze the role that increasing state fleet electrification may have on the charging demand at fleet parking facilities.

Identifying Electric Vehicles to Best Serve University Fleet Needs and Support Sustainability Goals Booth, S.; Bennett, J.; Helm, M.; Arnold, D.; Baker, B.; Clay, R.; Till, M.; Sears, T. 2/1/2022 Reports

Sawatch Labs, Denver, Colorado; National Renewable Energy Laboratory, Golden, Colorado

University fleets represent an enticing opportunity to explore the near-term feasibility of achieving net-zero-carbon emissions in transportation. In many instances, universities operate much like a small, self-contained ecosystem with all the same transportation needs as a larger municipality, but with a smaller geographic footprint. Their fleets often include a wide variety of vehicle types serving the campus, including low-speed vehicles (e.g., golf carts), light-duty sedans, SUVs, and pickups, as well as medium-duty trucks and delivery vehicles. The mix of vehicle and operational needs combined with broader activities related to net-zero campuses makes universities and colleges unique microcosms to determine the feasibility of and path to achieving net-zero fleets. As the availability of electric drivetrains expands beyond light-duty sedans, fleets need to understand when it will be operationally and financially appropriate to start adding electric drivetrains to their fleets. To better understand these opportunities, NREL contracted Sawatch Labs to analyze the role electric vehicles (EVs) can have in helping universities meet net-zero emissions and fleet sustainability goals they have instituted.

Electric Vehicle Supply Equipment Standards Technology Review 2/1/2022 Reports

California Air Resources Board, Sacramento, California

Zero-emission transportation is critical to achieving California’s air quality and climate goals. To support the adoption and use of zero-emission vehicles, the California Air Resources Board (CARB) adopted the Electric Vehicle Supply Equipment (EVSE) Standards Regulation in 2019 to reduce barriers to accessing public charging stations. The EVSE Standards Regulation establishes minimum requirements for payment methods an EVSE must allow, facilitates roaming agreements between electric vehicle service providers, creates a more complete database of location and pricing information for consumer use, and ensures clarity in the cost of a charging session. To assess barriers drivers may face and understand whether the requirements of the Regulation, particularly the requirement that EVSE must accept both chip payment cards and contactless, “tap” cards, CARB staff conducted a Technology Review. The Technology Review included an evaluation of the availability and use of different payment methods and a survey of drivers’ experiences accessing public charging stations. This report presents the findings and recommendations from that work.

Assessing the Value of EV Managed Charging: A Review of Methodologies and Results Anwar, M.; Muratori, M.; Jadun, P.; Hale, E.; Bush, B.; Denholm, P.; Ma, O.; Podkaminer, K. 1/7/2022 Journal Articles & Abstracts

National Renewable Energy Laboratory, Golden, Colorado; U.S. Department of Energy, Washington, D.C.

Driven by technological progress and growing global attention for sustainability, the adoption of electric vehicles (EVs) is on the rise. Large-scale EV adoption would both disrupt the transportation sector and lead to far-reaching consequences for energy and electricity systems, including new opportunities for significant load growth. Unmanaged EV charging can stress existing grid infrastructure, possibly leading to operational, reliability, and planning challenges both at the bulk and distribution levels. However, effective management of EV charging can resolve these challenges and provide additional value. This report summarizes the benefits of managed EV charging, provides an overview of the landscape of existing implementations and costs of managed charging in the United States, critically reviews the state of the art of methodologies in analysis/modeling studies, and quantifies the cost and benefits of managed charging as reported in the reviewed studies. Additionally, it distills several key insights outlining the factors affecting the value of managed EV charging and identifies critical gaps and remaining challenges to fully realize effective EV-grid integration.

EV Charging at Multi-Family Dwellings Lepre, N. 1/3/2022 Reports

Atlas Public Policy, Washington, DC

Approximately 30% of U.S. households are multi-family dwellings (MFDs), such as apartments and condos, and almost 75% of MFD households have at least one vehicle. Therefore, it is essential for electric vehicle (EV) charging to be available to MFD residents in order to make EVs an option for a large portion of the population. This paper draws on case studies, other research, and charging use data from the Columbus, Ohio area and New York state to summarize the key drivers and barriers for MFD building managers to install EV charging.

Clean Cities Coalitions 2020 Activity Report Singer, M.; Johnson, C. 12/29/2021 Reports

National Renewable Energy Laboratory, Golden, Colorado

Clean Cities coalition activities resulted in an EUI of nearly 1 billion GGE, comprised of net alternative fuels used and energy savings from efficiency projects, in 2020. Clean Cities coalition and stakeholder participation in vehicle and infrastructure development projects remained strong, although transportation activity and resulting EUI decreased in 2020 due to the COVID 19 pandemic. Coalition-reported activities prevented nearly 5 million carbon dioxide-equivalent tons of emissions (only GHG emissions are reported here; criteria pollutants and other emissions are not included in this report). The GHG benefits increased in 2020 despite a decrease in EUI because coalitions focused more on technologies with higher GHG benefits per GGE reduced and because the lifecycle of many alternative fuels such as electricity or biofuels is becoming less carbon intense. Coalitions were successful in securing project grant awards from numerous outside (non-DOE) sources. The 90 project grant awards in 2020 generated $151 million in funds from coalition members and project partners in addition to $12.8 million in DOE grant funds. Coalitions also collected $1.1 million in stakeholder dues and $3.1 million in operational funds from host organizations. In macro terms, this non-DOE supplemental funding represents a 4:1 leveraging of the $38 million that was included in the VTO Technology Integration budget in 2020. Clean Cities coordinators spent nearly 135,700 hours pursuing their coalitions’ goals in 2020. The average coordinator is quite experienced and has held the coordinator position for nearly eight years. Coordinators logged more than 3,290 outreach, education, and training activities in 2020, which reached an estimated 31 million people. Activities that reached underserved communities were tracked for the first time in 2020 and accounted for 17% of all activities.

Electric Vehicle Charging Infrastructure Trends from the Alternative Fueling Station Locator: Second Quarter 2021 Brown, A.; Levene, J.; Schayowitz, A.; Klotz, E. 12/16/2021 Reports

National Renewable Energy Laboratory, Golden, Colorado; ICF, Washington, D.C.

The U.S. Department of Energy’s Alternative Fueling Station Locator contains information on public and private non-residential alternative fueling stations in the United States and Canada and currently tracks ethanol (E85), biodiesel, compressed natural gas, electric vehicle (EV) charging, hydrogen, liquefied natural gas, and propane stations. Of these fuels, EV charging continues to experience rapidly changing technology and growing infrastructure. This report provides a snapshot of the state of EV charging infrastructure in the United States in the second calendar quarter of 2021. Using data from the Station Locator, this report breaks down the growth of public and private charging infrastructure by charging level, network, and location. Additionally, this report measures the current state of charging infrastructure compared with the amount projected to meet charging demand by 2030. This information is intended to help transportation planners, policymakers, researchers, infrastructure developers, and others understand the rapidly changing landscape for EV charging.

Electric Ride-Hailing Charging Infrastructure: Needs Assessment and Equitable Siting in Houston Hsu C.; Slowik, P. 10/21/2021 Reports

International Council on Clean Transportation, Washington, D.C.

The reach and use of ride-hailing services have greatly expanded in major urban areas in the United States and globally. As ride-hailing continues to grow as an important pillar of the mobility ecosystem, such fleets raise questions related to their environmental and mobility impacts, and electrification offers an opportunity to eliminate the vehicles’ local emissions. This paper quantifies the number of ride-hailing direct current fast chargers needed in Houston to support a growing electric ride-hailing fleet from 2021 through 2030. It identifies priority sites that expand infrastructure equity and access in the city, with a focus on city-owned properties. The paper also summarizes best practices in equitable clean mobility investments and discusses the policies and actions that can facilitate ride-hailing electrification and contribute to equitable outcomes.

There's No Place Like Home: Residential Parking, Electrical Access, and Implications for the Future of EV Charging Infrastructure Ge, Y.; Simeone, C; Duvall, A.; Wood, E. 10/1/2021 Reports

National Renewable Energy Laboratory, Golden, Colorado

The current foundation of U.S. charging infrastructure has been built upon charging at residential locations, where vehicles tend to be parked for long durations overnight. As the electric vehicle (EV) market expands beyond early adopters (typically high-income, single-family homes that have access to off-street parking) to mainstream consumers, planners must consider developing charging infrastructure solutions for households without consistent access to overnight home charging. In situations where residential off-street charging access is unattainable, a portfolio of solutions may be possible, including providing access to public charging in residential neighborhoods (on street), at workplaces, at commonly visited public locations, and (when necessary) at centralized locations via high power fast charging infrastructure (similar to existing gas stations). This report identifies charging access trends with respect to residence type and infers national residential charging access scenarios as a function of the national EV fleet size.
