Powering Progress: Advancing Transportation Electrification in Rural Southeastern Communities
7/1/2024
This report follows up on a 2022 Electrification Coalition report, Electric Vehicles (EVs) in Rural Communities, in addressing common roadblocks to transportation electrification in the rural, Southeast U.S. by providing case study examples of how communities have overcome these challenges. As rural communities are particularly susceptible to the effects of oil-dominated transportation systems, examples of successful electrification pathways are critical to wide-reaching EV deployment.
Advancing NEVI: Recommendations from State NEVI Funding Applicants
7/1/2024
This report from the National Association of State Energy Officials (NASEO) offers guidance to future applicants to the National Electric Vehicle Infrastructure (NEVI) funding program. NASEO uses information gleaned from candid, in-depth interviews of first-round NEVI awardees to offer seven key recommendations for future NEVI program leads. These recommendations focus on various aspects of the NEVI award process, including how to enhance proposal quality, streamline application reviews, and accelerate the deployment of NEVI-funded stations. The recommendations also come paired with action items to help applicants get their proposals off the ground.
Customer-Focused Key Performance Indicators for Electric Vehicle Charging
6/18/2024
Electric vehicles (EVs) are a rapidly growing portion of the light-duty vehicle market, but their sustained success is closely linked to the reliability and ease-of-use of public EV chargers. To mitigate issues such as long wait times, difficulties starting charging sessions, and slow charging speeds, this report recommends two sets of numerically defined key performance indicators (KPIs) based on customer pain points that will help streamline the transition to clean vehicles. These KPIs target the following: charger access, starting and completing a charge, and charger-related safety and comfort.

Navigating Options for Transportation Electrification and Solar Charging: Steps and Lessons Learned in Montana Communities
6/1/2024
Drawing on analysis and outreach in three Montana communities (Missoula, Bozeman, and Whitefish), this report provides guidance and best practices for other towns and cities across the country on how to effectively implement electric vehicle (EV) transportation options into their communities. The report incorporates logistical considerations—vehicle types, chargers, electricity generation—and useful strategies—effective stakeholder engagement, coordinating EV charging and renewable energy generation, and more—to cover the technological, economic, and environmental aspects of the transition to EVs.

Physical Safety and Security at Electric Vehicle Charging Sites
6/1/2024
As electric vehicle (EV) demand grows, so does the need for more robust EV charger safety and security. EV charger host sites must work to uplift driver and passenger confidence by incorporating design elements that promote greater safety and security. This help sheet outlines various best practices for public EV chargers. While the help sheet indicates the higher monetary costs attributed to greater safety and security measures, it also clarifies the greater repeat customers rates that result from these improvements.
Battery Energy Storage for Electric Vehicle Charging Stations
6/1/2024
This help sheet from the Department of Energy Joint Office of Energy and Transportation provides information on how battery energy storage systems can benefit electric vehicle (EV) fast charging infrastructure across the U.S. Specifically, the help sheet provides an overview of battery-buffered fast charging, as well its benefits, risks, and relevant use cases. The help sheet also provides guidance on how to begin implementing battery-buffered fast charging.
Grid-Constrained Electric Vehicle Fast Charging Sites: Battery-Buffered Options
6/1/2024
America’s electric vehicle (EV) charging network is growing quickly, but many rural regions across the country experience electrical grid restraints that complicate the EV charger build-out. Government agencies must still devise strategies for deploying chargers in these locations where electrical grid capacity is more limited. This technical assistance case study provides guidance on battery-buffered options for EV charging sites with limited grid capacity, including infrastructure solutions, project economics, energy specification methods, technical considerations, and other relevant strategies.
Best Practices for EV Carsharing Programs
6/1/2024
Carsharing programs are common throughout the U.S., but few so far have focused on electric vehicles (EVs). Over the past six years, Forth Mobility has developed and trialed several EV carshare programs to identify and better understand the best practices and roadblocks to implementing these programs in underserved areas, such as in low-income and rural communities. This paper shares lessons learned by analyzing the following subject areas: revenue planning; site host, technology platform, and vehicle type selection; educational outreach; marketing strategies; and community organization partnerships.

Solar Power + Electric Vehicle Charging: Capturing Synergies in Minnesota
6/1/2024
A suite of aggressive climate action legislation, including a series of solar development commitments, has contributed to Minnesota reducing the carbon intensity of its power sector by 29% over 2013 levels. However, the carbon footprint of each sector has not dropped equally. In 2018, the transportation sector overtook power generation as the leading emissions producer statewide. The same focus on solar energy—combined with electric vehicle (EV) use—offers a vital opportunity for Minnesota to decrease transportation emissions. The analysis in this report examines the underdeveloped synthesis between solar production and EV charging, presenting seven key findings paired with relevant recommendations to transform the market and decrease transportation-based emissions.

SiLVERS: St. Louis Vehicle Electrification Rides for Seniors Final Report
5/1/2024
Program-specific electric vehicle (EV) use cases can be particularly helpful towards nationwide EV adoption, as they prove EVs can perform as well, if not better, than their internal combustion counterparts. This case study highlights the successes, challenges, and lessons learned from a 3-and-a-half-year pilot program that employed EVs to deliver and transport senior citizens around the St. Louis area. The study demonstrates how electrifying social services not only maintains performance, but simultaneously reduces carbon emissions and saves on operating costs, the latter being a particularly significant factor for programs receiving little funding.

Study of Electric Vehicle Range Loss Associated with Replacement Tires
4/1/2024
This technical report from Oak Ridge National Laboratory (ORNL) examines how replacement tires affect the range of EVs, with a goal of supplementing the EV information made available to consumers on the FuelEconomy.Gov website. The report analyzes the change in range from worn tires versus replacement tires, paying particular attention to how tire friction impacts range losses. The report also compares worn, replacement, and original equipment manufacturer (OEM) tires across five EV models from different EV manufacturers. ORNL concludes that, compared to OEM tires, tire replacements reduce estimated EV range whereas worn tires increase estimated range.
