Proposal for the System of Dynamic Wireless Power Transfer Connected with Photovoltaic in the Off-Grid Environment

Electric Vehicles (EVs) are becoming increasingly popular as we move toward carbon neutrality. Dynamic Wireless Power Transfer (DWPT), which wirelessly supplies power to EVs while they are running, is being actively researched by organizations in various countries as a technology to solve the shortcomings of EVs. In addition, by obtaining the energy needed for EVs to run from renewable energy sources such as solar power, it can make a significant contribution to the achievement of carbon neutrality. Few studies have been conducted on systems that install Photovoltaic (PV) cells on the shoulder of a DWPT road and connect them directly to the DWPT system, and few of them are practical. In this paper, we propose a PV+DWPT system that combines a PV system and a DWPT system in an off-grid condition without being connected to the grid. Experiments with equipment simulating a DWPT confirmed that the proposed system works properly and demonstrated the effectiveness of the system.
