Charge Up Your Town: Best Management Practices to Ensure Your Town is EV Ready
11/1/2023
With a goal of reducing statewide greenhouse gas emissions by 80% below 2006 levels by 2050, the State of New Jersey is making a concerted effort to electrify its transportation sector, which currently produces over 40% of the state’s emissions. This paper provides a case study on how state governments can support local municipalities in successfully converting to light-duty electric vehicle (EV) fleets and installing adequate electric vehicle supply/service equipment (EVSE). As municipalities are often in charge of installing EVSE across New Jersey, local government understanding of statewide ordinances, EV charging station installation requirements, and available financial incentives is imperative towards achieving statewide emissions reduction targets. Other state and local governments can adapt this guide to meet their own parameters.
Grid Capacity – What is it, What Determines it, Does One Number Work, and How Does it Relate to Electric Vehicles?
11/1/2023
Electrical power is used in many facets of modern life and electricity demand continues to grow. The adoption of electric vehicles (EVs), migration from natural gas to electric heat pumps, and other decarbonization efforts are expected to grow this demand even further. With this increased demand, questions arise on if the power grid can handle this load and questions of “grid capacity” emerge. This report discusses common questions about what grid capacity is and how EVs impact grid capacity.

Electric Vehicle Charging Infrastructure Trends from the Alternative Fueling Station Locator: Second Quarter 2023
10/16/2023
Electric vehicle (EV) charging infrastructure continues to rapidly change and grow. Using data from the U.S. Department of Energy’s Alternative Fueling Station Locator, this report provides a snapshot of the state of EV charging infrastructure in the United States in the second calendar quarter of 2023 by charging level, network, and location. Additionally, this report measures the current state of charging infrastructure compared with a federal infrastructure requirement scenario. This information is intended to help transportation planners, policymakers, researchers, infrastructure developers, and others understand the rapidly changing landscape of EV charging infrastructure. This is the fourteenth report in a series.

Recommendations for Minimum Required Error Codes for Electric Vehicle Charging Infrastructure
9/13/2023
This report proposes a set of Minimum Required Error Codes (MRECs) for electric vehicle (EV) chargers and recommends that the industry implement these uniformly across the North American EV charging ecosystem to streamline error reporting, interpretability, and diagnostics. The purpose of this document is to simplify the troubleshooting process and increase charging reliability for all EV users. This report serves as a recommendation for industry stakeholders, encouraging a unified methodology to define and classify a minimum required set of error codes.
Fast Charging Infrastructure for Electrifying Road Trips to and from National Parks in the Western United States
9/12/2023
National parks in the Western United States draw over 80 million visitors every year, and most visitors rely on personal cars for their road trips (or long-distance travels). Travel to national parks represents distinct travel demand, as they are typically located in remote areas necessitating long-distance trips. This study investigates the quantity and locations of on-route fast charging infrastructure needed by 2030 to enable seamless travel to/from national parks using electric vehicles in seven target states in the region, employing unprecedented high-resolution spatial and temporal analysis.

Customer Experience at Public Charging Stations and Its Effects on the Purchase and Use of Electric Vehicles
9/1/2023
This report evaluates how consumer experiences at public fast charging stations influence electric vehicle (EV) adoption, including how it impacts the likelihood of current EV drivers purchasing EVs in the future. This report discusses how a better understanding about how the customer experience impacts the adoption of EVs could help create performance metrics for public EV charging stations and ensure that EV adoption meets federal and state goals in coming years.
At A Glance: Electric Vehicles
8/29/2023
Electric-drive vehicles use electricity as their primary fuel or to improve the efficiency of conventional vehicle designs. With the range of styles and options available, there is likely one to meet your needs. Electric vehicles (EVs) include all-electric vehicles and plug-in hybrid electric vehicles (PHEVs). Access this publication in Spanish here and French here.
Notes: This document is intended to be printed double-sided on an 8-1/2 X 11 piece of paper, then folded in half once to present as a brochure.
Electric Vehicle Basics
8/29/2023
Electric vehicles use electricity as their primary fuel or to improve the efficiency of conventional vehicle designs. These vehicles can be divided into two categories: All-electric vehicles and plug-in hybrid electric vehicles (PHEVs). Together, EVs and PHEVs can also be referred to as electric vehicles (EVs). Access this publication in Spanish and in French.
Streetlight Charging in the City Right-of-Way: A Community Perspective
8/1/2023
The Streetlight Charging in the City Right-of-Way project seeks to substantially increase access to electric vehicle (EV) charging in Kansas City, Missouri by combining charging stations with existing streetlight infrastructure. This report is an account of the community research conducted by the project team to engage residents in decision-making for charging station siting. The report details the current transportation concerns among residents, feedback from community members on the proposed charging sites, and community recommendations for additional sites.

Electric Vehicle Managed Charging: Estimating the Potential Bulk Power System Value
8/1/2023
Numerous studies have estimated the potential value of EV managed charging. In this study, NREL leveraged more detailed modeling of EV adoption, use, charging, and bulk power system operations to understand the potential value. Unique to this study, NREL modeled different charging flexibility types and dispatch mechanisms—as well as participation rates among drivers in having their EV charging managed—starting from vehicle-specific descriptions of charging flexibility.

Multi-Unit Dwelling Plug-in EV Charging Innovation Pilots
7/1/2023
Nearly one-third of residences in the U.S. are multi-unit dwellings (MUDs), e.g., apartments and condominiums, and multi-family housing buildings with five or more units account for approximately 45% of rental households. While 80% of electric vehicle (EV) charging takes place at home, less than 5% of home charging takes place at multi-family housing buildings. With public EV charging still underdeveloped, lack of access to reliable home charging is a major barrier to EV adoption for multi-family housing residents. Project partners led a three-year project to address barriers to EV charging at MUDs by developing an online toolkit geared toward residents, homeowner associations (HOAs), and property managers. The project engaged stakeholders across the country to identify real and perceived barriers to EV charging at multi-family housing buildings and explored innovative technologies that attempt to alleviate the identified barriers, which are discussed in this report.
