The effect of dynamic wireless charging systems on electric vehicle activation and sustainability

To address climate change, achieving carbon neutrality is imperative. Electric vehicles (EVs) stand out as the primary solution for achieving carbon neutrality in the transportation sector. However, the inconvenience associated with charging impedes widespread adoption of EVs. Dynamic wireless charging system (DWCS) present a promising solution to enhance charging convenience due to their greater accessibility compared to traditional charging infrastructure, along with reduced charging durations. Consequently, DWCS holds significant potential for promoting EV adoption and ensuring sustainability, yet this potential remains underexplored. In this study, a discrete choice model was developed to analyze the impact of charging convenience on vehicle choice through stated preference surveys and to evaluate the effect of enhancing charging convenience through the introduction of DWCS on the activation of EVs. Furthermore, it investigated the spatial distribution of EV activation effects concerning DWCS accessibility and estimated environmental benefits, such as reduced air pollutant emissions and associated economic gains. The introduction of DWCS in Seoul could potentially increase the market share of EVs by approximately 14% and result in air pollution reduction benefits amounting to 140.82 B KRW ($106.06 M) over a period of 10 years. These results underscore the significant potential of DWCS in promoting EV adoption and sustainability, hinting at its pivotal role in advancing toward widespread EV adoption.
