Smart grid architectures for dynamic wireless EV charging

摘要

Technologies are rapidly evolving in the area of Emobility. For example, dynamic wireless charging is a concept that aims at increasing vehicle range and decreasing battery size. In this case, vehicles charge as they move over the road surface in urban or highway environments. Due to in motion charging, journey idle time decreases whereas mileage and comfort increase. Moreover, smaller Electric Vehicle (EV) batteries are feasible due to such a mileage increase. However, the dynamic charging process has a severe impact on the power grid. In contrast to static charging that lasts for minutes up to hours, dynamic wireless charging is a much more variable process. Switching due to the layout of charging lanes can occur. When considering energy consumption, EVs can enable the utilization of unpredictable renewable energy sources such as wind and sun, thus decreasing environmental impact and in the long term, the associated energy production cost. In this paper, strategies to address the aforementioned issues with intelligent energy management will be presented.
