Electric Vehicle Charger Deployment Optimization
8/1/2022
As consumers begin to purchase electric vehicles (EVs) in greater volumes, the need for charging stations will increase. A one-size-fits-all deployment strategy of EV charging stations will not satisfy all needs or economic considerations. This study investigates how many charging stations and outlets may be required at various stages of the EV market development in different regions of the United States to satisfy actual demand and to instill within end users the confidence that availability will be sufficient. In addition, this study aims to better understand what types of chargers will be required at different locations to optimize deployment while reducing overall infrastructure costs and accelerating the business case for charger installation.
Grand Teton National Park Federal Fleet Tiger Team EVSE Site Assessment
8/1/2022
In developing and implementing federal zero-emission vehicle (ZEV) fleet strategy, agencies should focus on evaluating electric vehicle (EV) 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 (EVSE) deployment strategies. This site report supports the development of a ZEV deployment plan for the Grand Teton National Park that can ultimately be incorporated into the overall U.S. Department of the Interior ZEV fleet strategy.

Charged Up! TLC Electrification Report
7/1/2022
The New York City Taxi & Limousine Commission (TLC) is committed to transitioning the majority of its licensed fleet to electric vehicles (EVs) by 2030. Charged Up! is TLC’s roadmap to support this movement, outlining ways to support TLC’s EV drivers, incentivize more EVs, and support the for-hire industry’s charging needs. New York City’s for-hire transportation landscape presents distinct challenges to electrification, with high daily mileage driven due to high trip volumes, drivers living in the outer boroughs and in environmental justice communities, as well as the various charging needs of industry stakeholders. Given these considerations, the report identifies policy levers and formulates recommendations to address three major barriers that currently impede the expansion of for-hire EVs.
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.

Electric Vehicles for Fleets
5/17/2022
Electric vehicles can fulfill many daily driving needs, making them a great solution for fleets. They offer several benefits and can fill roles in light-duty, medium-/heavy-duty (MD/HD), and even off-road applications. The unique fleet environment presents considerations beyond those that consumers must address before going electric. For example, fleet managers must understand the impacts of charging multiple vehicles while maintaining fleet operations. Larger MD/HD vehicles bring additional factors to consider.

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.
