Public perceptions of dynamic wireless power transfer technology: A case study of Greater Lafayette, Indiana

• Investigates public perceptions of Dynamic Wireless Power Transfer in Indiana. • Employs a mixed-methods approach and the Social Acceptability Framework. • Identifies three main themes of public concern regarding transportation electrification. • Proposes DWPT outreach strategies based on target demographics. The widespread adoption of electric vehicles (EVs) faces three main challenges: purchase price, lack of charging infrastructure, and long charging time. Dynamic Wireless Power Transfer (DWPT) is a promising solution because it maintains the level of charge of the EV while in motion, potentially reducing battery size, vehicle cost, and charging inconvenience. This study investigates public perceptions of DWPT in Indiana, where the Indiana Department of Transportation is piloting the technology. It also provides policy recommendations to increase acceptance of DWPT technology, especially through public education and engagement. Using a mixed-methods approach and based on the Social Acceptability Framework, we analyzed data from a stated preference survey (n = 275) disseminated during the DWPT testbed construction in the Greater Lafayette area in Indiana. Our analyses identified three major thematic categories of interest to respondents: economics, health and the environment, and barriers to EV adoption. Our results suggest that some respondents thought the technology can improve the availability of EVs and expand charging networks. Others looked forward to more affordable EVs through new government incentives or reduced battery sizes and costs enabled by DWPT. Respondents also raised questions about funding, emphasizing that infrastructure investments should benefit all the local population. Cost concerns were statistically related to party affiliation and EV ownership status. While respondents recognized the public health benefits of EVs, others expressed skepticism about DWPT’s environmental footprint, citing concerns over lifecycle emissions and construction-related impacts. This research enhances our understanding of local perspectives on DWPT and highlights the importance of public education and engagement. Findings inform outreach strategies to broaden support for roadway electrification.
