Will Advanced Public Charging Infrastructure Speed Up Electrification of Future Transportation?

This study focuses on evaluating impacts of advanced, urban public charging infrastructure on the battery electric vehicle (BEV) adoption in the U.S market. Under various infrastructure scenarios (e.g., current and developed conditions), we investigate the infrastructure impacts on the near-term BEV adoption using a consumer-choice based market simulation approach. Our results suggest that current public charging infrastructure has continuous and significant impacts on the near-term BEV adoption. Additional infrastructure investment could further stimulate the public acceptance of BEVs. We also find that the actual infrastructure impact may vary depending on the assumption of how charging deployment could affect consumers' access of chargers and consumers' daily available charging time. However, this impact variability could be reduced when infrastructure is getting mature.
