Abstract
SummaryWireless power transfer network (WPTN) can provide efficient, timely, and dynamic charging service for multiple devices wirelessly by adopting mobile chargers. However, there are still urgent requirements to reduce the cost and improve the charging performance of WPTN. Therefore, this paper proposes the charging scheduling strategy for linear WPTN in which devices are distributed linearly or approximately linearly. An improved energy consumption model of the WPTN node is discussed firstly. Then, considering the charging capability of the wireless power transfer module, a charging threshold is selected to improve energy use efficiency. Moreover, the regional charging of mobile chargers is realized, so the distribution of carried energy on mobile chargers could be balanced and the maximum required energy that a single mobile charger carried could be reduced. Meanwhile, the processes of charging scheduling and energy delivery are analyzed in detail. Finally, simulation analysis and experimental data verify the effectiveness of the proposed charging scheduling strategies.
