Community Impacts: Accessible Electric Vehicle Carshare Programs
6/6/2022
Having abundant and affordable access to transportation affects an individual’s ability to live a healthy and fulfilling life. To date, a majority of carshare models have been implemented in urban, affluent areas, and have not focused on electric vehicles (EVs). A variety of EV carshare programs were evaluated with the goal of identifying and understanding best practices and challenges associated with implementing these programs in underserved locations, specifically in low-income and rural areas. This paper shares the design and results to date of several of these programs, as well as a framework for designing a carshare program.

Review of Electric Vehicle Charger Cybersecurity Vulnerabilities, Potential Impacts, and Defenses
5/26/2022
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
5/21/2022
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.

Golden Gate National Recreation Area Federal Fleet Tiger Team EVSE Site Assessment
5/2/2022
The U.S. Department of Energy Federal Energy Management Program helps federal agencies reduce petroleum consumption and increase alternative fuel use through its resources for the Sustainable Federal Fleets program. A key element of this assistance involves supporting agencies in the transition to zero-emission vehicles (ZEVs). In developing and implementing their ZEV fleet strategies, agencies should focus on evaluating electric vehicle deployment opportunities at individual fleet locations, which have unique site, vehicle operating, and utility service characteristics. This is best achieved through site assessments to evaluate opportunities for ZEV acquisitions, identify optimal ZEV candidates, and determine optimal electric vehicle supply equipment deployment strategies. This site report supports the development of a ZEV deployment plan for the Golden Gate National Recreation Area, which can ultimately be incorporated into the overall U.S. Department of the Interior ZEV fleet strategy.

Charting the Course for Early Truck Electrification
5/2/2022
Trucks in the United States produce 25% of transportation greenhouse gas emissions even though they only make up 10% of vehicles on the road. Across the United States, fleets have already committed to deploying over 140,000 electric vehicles. Although this trend is enabled by technology, regulation is also encouraging electric truck adoption. California now requires truck builders to sell an increasing percentage of electric trucks in the state. And 15 additional states signed a joint memorandum of understanding to follow California’s path. This report uses real-world observed trucking telematics data from Geotab to investigate which trucks in California and New York can electrify the fastest based on currently available electric truck models. The report also examines the amount of energy and charging infrastructure that these early electrifiable trucks need, in addition to emissions from the grid under various charging schedules.

2021 Zero Emission Vehicle Market Study: Volume 2: Intra-California Regions Defined by Air Districts
4/14/2022
California set a goal to transition new light-duty vehicle sales to 100% zero emissions vehicles (ZEVs) by 2035. To assist California and the other ZEV states to monitor and manage the success of policies promoting ZEVs and ZEV fueling infrastructure deployment, this research assesses car-owning households’ responses to these new technology vehicles and new fueling behaviors. This report assesses the readiness of household consumers in California to support state goals, i.e., as goals become more ambitious and requirements on manufacturers increase, are more car-owning households poised to become ZEV buyers? The analysis explores differences within California, based on boundaries of air quality districts. This study question is addressed via comparison of two large sample surveys of car-owning households. These surveys were completed in first calendar quarters of 2019 and 2021. Both questionnaires measure consumer awareness, knowledge, assessments, and consideration of ZEVs. Note:
