Prototype design of energy management system for mobile device via Wireless Charging Robot

In recent years, energy management of the mobile device is researched in two approaches; energy saving and energy charging. In terms of energy charging, though the wireless charging and the energy harvesting technologies have been proposed, these technologies could not satisfy all of the criteria; location-free, connection-free, reliable and human-safe. In response, the authors are proposing a new energy management method for mobile device based on the Wireless Charging Robot (i.e., mobile robot with wireless charging function via magnetic coupled resonances). It operates in the combination of two charging tasks; charging the mobile device from robots (i.e., mobile device charging task), and charging the robot from charging stations connected to power system (i.e., self charging task). In this manner, robots mediate the energy delivery from the power system to the mobile devices, and consequently, the system satisfies all of these criteria. This paper introduces the abstract architecture and procedure of the overall system with the basic method for designing the wireless charging function in the energy management system.
