Reports & Resources

Electric vehicle (EV) research in Vermont is rapidly evolving to match the speed of vehicle and technology innovations. Several recent reports on EVs in Vermont are highlighted below, including information on EV interactions with utility infrastructure and how public entities can support increased public charging stations. Please contact us if you are aware of materials which should be added to this listing.

Regional Planning for Electric Vehicles

The Chittenden County Regional Planning Commission (CCRPC) has EV resources for communities working to reduce greenhouse gas emissions from the transportation sector and increase the energy efficiency of Vermont’s motor vehicle fleet.

SUMMARY: CCRPC recognizes electric vehicles are an important factor in realizing energy efficiency improvements and greenhouse gas reductions detailed in the 2013 Chittenden County ECOS Plan and the Chittenden County Climate Action Guide, as well as climate action plans across all levels of government.  The Chittenden County Climate Action Guide prioritizes the promotion of electric vehicle infrastructure for electric vehicle charging as a key action to meeting greenhouse gas reduction targets established by the State legislature. Electric Vehicle (EV) technology supports these goals by providing low carbon, highly efficient and cost effective transportation.  As such, CCRPC collaborated with Vermont Energy Investment Corporation (VEIC) to develop studies on future EV adoption and EV charging equipment locations, a how-to guide for installing EV charging equipment, and model bylaw language for streamlining permitting for new EV charging installations.

Planning for an electric vehicle infrastructure

Vermont Energy Investment Corporation identifies criteria for optimal locations for electric vehicle public charging, options for funding, and charging equipment for Chittenden County, Vermont.

SUMMARY: As electric vehicle sales continue to grow in Vermont, it is imperative that we begin to plan for widespread use of these vehicles and understand potential need for public charging facilities. Availability of away-from-home charging is one of the primary factors thought to affect consumers’ decisions regarding the purchase of an EV (along with vehicle price, vehicle range, and gasoline costs). In this report we consider needs for public vehicle charging in Chittenden County in the coming decade (2013-2023) as well as business models, optimal electric vehicle charging equipment (EVCE) location criteria in keeping with the ECOS planning goals and explore the different types of EVCE available.

Using US EIA projections of EV sales, we estimate that by 2023 approximately 5,800 EVs will be registered in Vermont, requiring 79 charging stations in Chittenden County. Cost estimates to install these charging stations varied from $553,000 to $1.66 million.We identify priority destination-types for public EVCE as those locations offering retail, recreation, and public administration services. These destinations commonly have dwell times long enough to allow an appreciable amount of charging. Future research may consider specific locations to serve as optimal sites for public EVCE in Chittenden County.

What's the most efficient way to charge electric vehicles?

Vermont Energy Investment Corporation presents data that shows level 2 electric vehicle charging to be consistently more efficient than level 1 charging.

SUMMARY: Uncontrolled EV charging may create the need for additional infrastructure and result in longer and higher peak demand. In order to meet this increased load without substantial expansion of generation capacity, it is critical that EV charging be performed as efficiently as possible. 

Identifying opportunities for applying efficiency measures to EVs requires analysis of energy usage from the point it flows from the grid to its release in the wheels of the vehicle. This includes the following two primary processes:

  • Charging: Storage of electrical energy in the EV battery system
  • Driving: Transformation of electrical energy into motion

This study analyzes one aspect of EV charging: the differences between Level 1(120V) and Level 2(240V) charging efficiency.

How will electric vehicles affect Vermont's electric grid?

The University of Vermont Transportation Research Center has completed several research studies investigating how the electric grid may respond under widespread use of EVs in Vermont.

SUMMARY: In this study, funded by the US DOT and Vermont utilities, volunteer drivers will use the PHEV for their regular daily travel, and from these trips, data will be collected about carbon emissions, electricity use, local variations in the electrical supply, and performance over differing distances and driving styles. The research also includes an on-going effort to determine the capacity of Vermont's electric grid to handle 50,000, 100,000 or 200,000 plug-in hybrids.
