Measuring electric vehicle owners’ willingness to participate in smart charging programs
As power systems transition to renewable energy, integrating battery electric vehicles (BEVs) into grid operations presents new opportunities and challenges for managing electricity demand and the associated environmental impacts from BEV charging. This study examines two grid-integration strategies: supplier-managed charging (SMC), which gives utilities control over charging timing, and vehicle-to-grid (V2G), which transforms BEVs into distribut…
Battery-powered bargains? Assessing electric vehicle resale value in the United States
The resale market will play a critical role in expanding plug-in electric vehicle (PEV) adoption to middle- and lower-income households. Understanding PEV depreciation trends in comparison to those of conventional gasoline vehicles (CVs) is critical for assessing PEV affordability and informing relevant policy, such as subsidies for used PEVs. We deliver comprehensive, high-resolution estimates of value retention rates at the make-model level in …
Not all subsidies are equal
Financial incentives, such as purchase subsidies, have been found to increase plug-in electric vehicle (PEV) adoption, but how these incentives are designed can impact their effectiveness as well as how equitably they are distributed. Using a national conjoint survey ( N = 2170 respondents), we quantify how U.S. vehicle buyers value different features of PEV financial incentives. Participants overwhelmingly prefer immediate rebates, on average va…
Electric vehicle adoption
Plug-in electric vehicles (PEVs) offer a promising pathway to decarbonizing the personal transportation sector, but PEV sales remains low. Prior research has found that direct experience with PEVs increases consumers’ stated purchase consideration, but these studies have used relatively long exposure times (days to months) with a PEV. To assess the effect of shorter exposure times (e.g. minutes) on stated purchase consideration, we conducted an e…
Choice at the pump
A decarbonized future will require a transition to lower carbon fuels for personal transportation. We study consumer preferences for combustion fuels including gasoline, diesel, natural gas, and E85 (85% ethanol and 15% gasoline) using consumer choice survey data from two settings: online ( n = 331) and in-person at refueling stations ( n = 127). Light-duty vehicle owners were asked in a series of choice tasks to choose among fuels that varied in…
