论文摘要
物联网（IoT）通过连接各种电子设备来为智能城市提供动力。 IoT设备的电源问题由于电池耐力差以及麻烦的电缆部署而构成了当前物联网开发的重大挑战。无线功率传输（WPT）技术最近已成为一种有前途的解决方案。但是，现有的WPT进展无法像Wi-Fi通信一样支持免费和移动充电。为此，提出了移动能源传输（MET）的概念，该概念依赖于共振光束充电（RBC）技术。自适应（a）RBC技术建立在RBC上，但旨在通过在设备首选电流和电压水平的设备充电设备进行自适应以提高充电效率。依靠自适应源功率控制开发了移动ARBC方案。使用1,000mAh锂离子电池的大量数值模拟表明，移动ARBC的表现优于简单的充电方案，例如恒定功率充电，配置自动充电和节省能源的距离自动充电。
Internet of things (IoT) is powering up smart cities by connecting all kinds of electronic devices. The power supply problem of IoT devices constitutes a major challenge in current IoT development, due to the poor battery endurance as well as the troublesome cable deployment. The wireless power transfer (WPT) technology has recently emerged as a promising solution. Yet, existing WPT advances cannot support free and mobile charging like Wi-Fi communications. To this end, the concept of mobile energy transfer (MET) is proposed, which relies critically on an resonant beam charging (RBC) technology. The adaptive (A) RBC technology builds on RBC, but aims at improving the charging efficiency by charging devices at device preferred current and voltage levels adaptively. A mobile ARBC scheme is developed relying on an adaptive source power control. Extensive numerical simulations using a 1,000mAh Li-ion battery show that the mobile ARBC outperforms simple charging schemes such as the constant power charging, the profile-adaptive charging, and the distance-adaptive charging in saving energy.
