Assessing Preferences for Dynamic Wireless Power Transfer in Public Charging Choices Among Experienced and non-Experienced EV Users

This paper explores preference for dynamic wireless power transfer (DWPT) technology in public charging choices. DWPT can alleviate range anxiety and charging time as barriers to electric vehicle (EV) use. Using the case of Indiana, this study designed a stated choice (SC) experiment, presenting respondents with various scenarios for extended electric vehicle (EV) trips. Integrated choice latent variable (ICLV) model was estimated to determine the factors influencing public charging decisions, particularly from the perspectives of experienced and non-experienced EV users. In general, DWPT is a more suitable option for experience users, however, the result remains inconclusive due to insignificant estimation. Conversely, nonexperienced users exhibit a negative perception towards DWPT relative to Level 2 charging. Moreover, experienced users are more sensitive to charging cost which make it necessary to make sure DWPT charging fee is competitive among other options. The non-experienced female also finds DWPT an unsuitable option, which corresponds to the charging preference distribution where DWPT is the least chosen option. Recognizing these nuanced preferences can assist policymakers in formulating targeted strategies to optimize public charging utilization and attract a broader spectrum of EV adopters, with DWPT emerging as a central focus in this endeavor.
