Similar to the evolution from the wired Internet to mobile Internet (MI), the growing demand for power delivery anywhere and anytime appeals for power grid transformation from wired to mobile domain. We propose here the next generation of power delivery network -- mobile power network (MPN) for wireless power transfer within a mobile range from several meters to tens of meters. At first, we present the MPN's concept evolution and application scenarios. Then, we introduce the MPN's supporting technology, namely resonant beam charging (RBC). As a long-range wireless power transfer (WPT) method, RBC can safely deliver multi-Watt power to multiple devices concurrently. Meanwhile, the recent progress in RBC research has been summarized. Next, we specify the MPN's architecture to provide the wide-area WPT coverage. Finally, we discuss the MPN's features and challenges. MPN can enable the ultimate mobility by cutting the final cord of mobile devices, realizing the "last-mile" mobile power delivery.
翻译：我们在此提议下一代电力传输网络 -- -- 移动电网,用于在几米至数十米范围内的移动范围内无线电力传输。我们首先介绍MPN的概念演变和应用设想。然后,我们引入MPN的支持技术,即共振波束充电(RBC)。作为远程无线电传输(WPT)方法,RBC可以安全地同时向多个设备传输多瓦电。与此同时,我们总结了RBC研究的最新进展。接下来,我们指定了MPN的架构,以提供广域WPT覆盖。最后,我们讨论了MPN的特征和挑战。MPN能够通过切断移动设备的最后电线,实现“最后一英里”移动电源的传输,实现最终的流动性。
