The utilization of electric vehicle (EV) charging equipment is a key driver of charging station economics, but current trends and factors related to the utilization of public charging infrastructure in the United States are not well understood. This study analyzes EV charging data from 3,705 nationwide public Level 2 and direct current fast charging stations over 2.5 years (2019–2022), observing utilization patterns over time. This study fills a critical research gap by reporting updated public charging station utilization statistics and analysis for the U.S. market.

Demand for electric vehicles (EVs) is increasing. Electricity is cheaper and cleaner than conventional fuel, and EV maintenance costs are low. Also attractive are EVs' instant torque and quiet operation. In addition to advantages for individual drivers and for fleets, the multiple fuel sources used to generate the electricity that powers EVs create more energy resilience for the transportation sector, which supports national security. With this uptick in EV demand comes questions about their batteries, how they are made, their safety, and what happens to them at the end of a vehicle's life.

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.

The Propane Education and Research Council (PERC) has engaged with the National Renewable Energy Laboratory (NREL) to develop information that is critical to understanding the current and future landscape for renewable propane (RP) and the value proposition for recovery of RP from existing and planned HEFA biorefineries. In summary the following outcomes are identified from this study: (1) production of incremental RP by increasing the severity of the hydroisomerization step is insignificant to the overall propane yield from a HEFA biorefinery, however production of renewable butane (or LPG2) is quite significant thus suggesting alternate strategies for valorizing these fractions; (2) the value proposition for recovering RP and renewable LPG is quite strong, with capital recovery payback periods of 14 months for a small biorefinery producing 3.5 million gallons per year RP to as short as 2 months for a large biorefinery producing 87 million gallons per year RP. Paybacks for renewable LPG are as much as 50% shorter; and (3) current and projected expansions of renewable diesel will greatly expand the potential availability of RP as a by-product. Several promising new pathways are under development but will not significantly increase production of RP for the next decade.

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.

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.
