Implementing Workplace Charging within Federal Agencies
4/19/2017
This case study, prepared for the U.S. Department of Energy Vehicle Technologies Office, draws from available information and lessons learned from federal agencies that have piloted plug-in electric vehicle (PEV) workplace charging programs. It can be challenging for organizations to involve all the key stakeholders needed to develop a charging program, but engaging them at an early stage can simplify the process of setting an adequate plan for the workplace. Key stakeholders may include workplace charging managers, facilities managers, parking managers, employee PEV drivers, legal counsel, employee benefits managers, and union representatives.
Multiple PEV charging stations are available on the GSA schedule. Agencies will need to select the charging station type and design that is most appropriate for each specific worksite - Level 1, Level 2, or DC Fast Charging. In addition, the GSA Blanket Purchase Agreement (BPA) can help reduce upfront costs, which will help keep the reimbursement fees within the threshold of what employees are willing to pay.

Field Evaluation of Medium-Duty Plug-in Electric Delivery Trucks
12/16/2016
This report focuses on medium-duty electric delivery vehicles operated by Frito-Lay North America (FLNA) at its Federal Way, Washington, distribution center. The 100% electric drive system is an alternative to conventional diesel delivery trucks and reduces both energy consumption and carbon dioxide (CO2) emissions. The vehicles' drive cycles and operation are analyzed and compared to demonstrate the importance of matching specific electric vehicle (EV) technologies to the appropriate operational duty cycle. The results of this analysis show that the Smith Newton EVs demonstrated a 68% reduction in energy consumption over the data reporting period compared to the conventional diesel vehicles, as well as a 46.4% reduction in CO2 equivalent emissions based on the local energy generation source. In addition to characterizing the in-use performance of the EVs compared to the conventional diesels, detailed facility load data were collected at the main building power feed as well as from each of the 10 EV chargers to better understand the broader implications associated with commercial EV deployment. These facility loads were incorporated into several modeling scenarios to demonstrate the potential benefits of integrating onsite renewables.

12/12/2016
In June 2016, the Workplace Charging Challenge distributed its third annual survey to 295 partners with the goal of tracking partners' progress and identifying trends in workplace charging. This document summarizes findings from the survey and highlights accomplishments of the EV Everywhere Workplace Charging Challenge.
National Economic Value Assessment of Plug-in Electric Vehicles: Volume I
12/1/2016
The adoption of plug-in electric vehicles (PEVs) can reduce household fuel expenditures by substituting electricity for gasoline while reducing greenhouse gas emissions and petroleum imports. A scenario approach is employed to provide insights into the long-term economic value of increased PEV market growth across the United States. The analytic methods estimate fundamental costs and benefits associated with an economic allocation of PEVs across households based upon household driving patterns, projected vehicle cost and performance attributes, and simulations of a future electricity grid. To explore the full technological potential of PEVs and resulting demands on the electricity grid, very high PEV market growth projections from previous studies are relied upon to develop multiple future scenarios.

Protecting Public Health: Plug-In Electric Vehicle Charging and the Healthcare Industry
10/10/2016
In 2014, the U.S. transportation sector consumed more than 13 million barrels of petroleum a day, approximately 70% of all domestic petroleum consumption. Internal combustion engine vehicles are major sources of greenhouse gases (GHGs), smog-forming compounds, particulate matter, and other air pollutants. Widespread use of alternative fuels and advanced vehicles, including plug-in electric vehicles (PEVs), can reduce our national dependence on petroleum and decrease the emissions that impact our air quality and public health. Healthcare organizations are major employers and community leaders that are committed to public wellbeing and are often early adopters of employer best practices. A growing number of hospitals are offering PEV charging stations for employees to help promote driving electric vehicles, reduce their carbon footprint, and improve local air quality.

Utilities Power Change: Engaging Commercial Customers in Workplace Charging
6/29/2016
As stewards of an electric grid that is available almost anywhere people park, utilities that support workplace charging are uniquely positioned to help their commercial customers be a part of the rapidly expanding network of charging infrastructure. Utilities understand the distinctive challenges of their customers, have access to technical information about electrical infrastructure, and have deep experience modeling and managing demand for electricity. This case study highlights the experiences of two utilities with workplace charging programs.

Drive Electric Vermont Case Study
3/21/2016
The U.S. Department of Energy's EV Everywhere Grand Challenge is working to identify barriers and opportunities to plugin electric vehicle (PEV) adoption. The Department of Energy developed a case study with Drive Electric Vermont to identify the lessons learned and best practices for successful PEV and charging infrastructure deployment in small and midsize communities. This is a snapshot of the findings.

Workplace Charging Challenge, Mid-Program Review: Employees Plug In
12/1/2015
This Program Review takes an unprecedented look at the state of workplace charging in the United States -- a report made possible by U.S. Department of Energy leadership and valuable support from our partners as they share their progress in developing robust workplace charging programs. Through the Workplace Charging Challenge, more than 250 participants are accelerating the development the nation's worksite PEV charging infrastructure and are supporting cleaner, more convenient transportation options within their communities. Challenge partners are currently providing access to PEV charging stations at more than 440 worksites across the country and are influencing countless other organizations to do the same.

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.
