Electric Vehicle Inventory and Use Survey (eVIUS)

The Electric Vehicle Inventory and Use Survey (eVIUS) is a United States Department of Transportation (USDOT) program aimed at gaining a deeper understanding of electric vehicle characteristics, usage levels, and charging patterns in the United States. The methodology for the eVIUS program will be an extension of the methodology used in the Vehicle Inventory and Use Survey (VIUS) program, which has run from 1997 to present and the Truck Inventory and Use Survey (TIUS) program, which ran from 1967 to 1992. The eVIUS survey will specifically target battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), surveying a sufficient number of respondents to enable the publication of relevant estimates on a national scale. Electric Vehicles (EVs) are a small proportion of the total US vehicle fleet (1% ), and they are primarily concentrated in the passenger vehicle classes but are also represented across all Gross Vehicular Weight Rating (GVWR) up to, and including, Class 8 vehicles. A separate survey, focused on the EV population, is needed to adequately analyze EV usage and charging patterns. The Bureau of Transportation Statistics (BTS) is seeking approval to conduct a voluntary survey from a sample of registered EVs. These will include both personal and commercial EV registrations. This survey will be administered to a random sample of registered EVs. A set of the questions focus on collecting data for usage during 2023, while other questions ask about general or typical use. BTS will reach out to the individual or business identified on the registration to obtain responses. BTS will maintain both the survey responses and the administrative data associated with the sample frame (e.g., vehicle make, model, year). BTS will keep the data private and secure in accordance with Confidential Information Protection and Statistical Efficiency Act of 2002 (Title 5 of Public Law 107-347) (CIPSEA) and the Foundations for Evidence-Based Policymaking Act of 2018 (Title 3 of Public Law 115-435). The data will be used to provide aggregate national statistics as well as breakdowns by state and GVWR if the data allows.
