Characterize the Demand and Energy Characteristics of Direct Current Fast Chargers
6/1/2015
The EV Project partnered with city, regional and state governments, utilities, and other organizations in 18 cities to deploy about 12,500 public and residential charging stations. It also demonstrated 8,650 plug-in electric vehicles. The focus of this paper is to identify the impact of direct current (DC) fast chargers charging on the total system load. It also identifies the characteristics of the aggregated group of DC fast chargers and a single typical DC fast charger and its charge profile or load duration curve.

Effects of Regional Temperature on Electric Vehicle Efficiency, Range, and Emissions in the United States
2/11/2015
We characterize the effect of regional temperature differences on battery electric vehicle (BEV) efficiency, range, and use-phase power plant CO2 emissions in the U.S. The efficiency of a BEV varies with ambient temperature due to battery efficiency and cabin climate control. We find that annual energy consumption of BEVs can increase by an average of 15% in the Upper Midwest or in the Southwest compared to the Pacific Coast due to temperature differences. Greenhouse gas (GHG) emissions from BEVs vary primarily with marginal regional grid mix, which has three times the GHG intensity in the Upper Midwest as on the Pacific Coast. However, even within a grid region, BEV emissions vary by up to 22% due to spatial and temporal ambient temperature variation and its implications for vehicle efficiency and charging duration and timing. Cold climate regions also encounter days with substantial reduction in EV range: the average range of a Nissan Leaf on the coldest day of the year drops from 70 miles on the Pacific Coast to less than 45 miles in the Upper Midwest. These regional differences are large enough to affect adoption patterns and energy and environmental implications of BEVs relative to alternatives.

Workplace Charging: Comparison of Sustainable Commuting Options
11/18/2014
Reducing greenhouse gas emissions (GHG) from employees' commutes, also known as Scope 3 emissions, is a top priority for many organizations interested in minimizing their carbon footprint. Scope 3 emissions are indirect GHG emissions from sources not owned or directly controlled by the organization but are related to their activities, including emissions from an employee's commute. Employers interested in investing in GHG emissions reduction efforts may want to compare the benefits of workplace charging to other commuter emission reduction investments such as subsidized public transportation or carpooling. The GHG emissions reduction benefit of workplace charging per dollar is comparable to, and in some cases greater than, other commuting options.

ADA Requirements for Workplace Charging Installation
11/3/2014
The Americans with Disabilities Act (ADA) is a federal civil rights law that prohibits discrimination in public places against individuals with disabilities. As an employer installing plug-in electric vehicle (PEV) charging stations, also known as electric vehicle supply equipment (EVSE), you need to follow special design guidelines to accommodate people with disabilities, as required by the ADA.

Geography of Existing and Potential Alternative Fuel Markets in the United States
11/3/2014
When deploying alternative fuels, it is paramount to match the right fuel with the right location, in accordance with local market conditions. We used six market indicators to evaluate the existing and potential regional market health for each of the five most commonly deployed alternative fuels: electricity (used by plug-in electric vehicles), biodiesel (blends of B20 and higher), E85 ethanol, compressed natural gas (CNG), and propane. Each market indicator was mapped, combined, and evaluated by industry experts. This process revealed the weight the market indicators should be given, with the proximity of fueling stations being the most important indicator, followed by alternative fuel vehicle density, gasoline prices, state incentives, nearby resources, and finally, environmental benefit. Though markets vary among states, no state received 'weak' potential for all five fuels, indicating that all states have an opportunity to use at least one alternative fuel. California, Illinois, Indiana, Pennsylvania, and Washington appear to have the best potential markets for alternative fuels in general, with each sporting strong markets for four of the fuels. Wyoming showed the least potential, with weak markets for all alternative fuels except for CNG, for which it has a patchy market. Of all the fuels, CNG is promising in the greatest number of states--largely because freight traffic provides potential demand for many far-reaching corridor markets and because the sources of CNG are so widespread geographically.

Clean Cities 2013 Annual Metrics Report
10/20/2014
Each year, the U.S. Department of Energy asks its Clean Cities program coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online database that is maintained as part of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions. They also submit data about sales of alternative fuels, deployment of alternative fuel vehicles (AFVs) and hybrid electric vehicles (HEVs), idle-reduction (IR) initiatives, fuel economy activities, and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use reduction impacts, which are summarized in this 2013 Annual Metrics Report.

Distributed Solar Photovoltaics for Electric Vehicle Charging: Regulatory and Policy Considerations
9/1/2014
Increasing demand for EV charging provides an opportunity for market expansion of distributed solar technology. A major barrier to the current deployment of solar technology for EV charging is a lack of clear information for policymakers, utilities, and potential adopters. This paper introduces regulatory and policy options available to policymakers and regulators wanting to incentivize solar EV charging. Additionally, it summarizes considerations regarding EV charging during the day versus at night and benefits and grid implications of combining solar and EV charging technologies.
