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.

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.
