Vehicle-to-vehicle wireless power transfer: Paving the way toward an electrified transportation system

摘要

To date, three major hurdles have hindered widespread adoption of electric vehicles (EVs): the high cost of batteries, insufficient public charging infrastructure, and the limited driving range of EVs. This study overcomes these three hurdles by introducing a new concept of vehicle-to-vehicle wireless power transfer (V2V WPT) between EVs to facilitate frequent, real-time, and on-demand charging. V2V WPT is enabled by the connected and automated vehicle technology and the sharing economy, and facilitates transfer of power between peer EVs. We formulate the problem of routing, scheduling, and matching vehicles in a V2V WPT platform on a energy-time expanded network, and devise a dynamic programming solution methodology to find the solution efficiently. We quantify the impact of adopting this technology in terms of system-wide energy savings, charging infrastructure requirements, and travel times, and investigate the possibility of reducing battery capacity in EVs as a result of this technology.
