“…Another critical aspect is the misalignment of the WPT coils due to an imprecise landing of the drone that can lead to a reduction of the coupling factor between coils, and therefore of the electrical performance. These two aspects have been investigated in the recent past, and several solutions have been presented [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. All the proposed solutions were mainly derived by previous WPT applications in other fields such as automotive or consumer electronics, and the main focus was on adapting these techniques to drones.…”

“…Here, a completely innovative solution is proposed. The major issues to recharge drone batteries by WPT systems are described in several past works [14][15][16][17][18][19]. In [15], a simple charging system is realized using two circular planar spiral coils, the transmitting one placed on the charging pad and the receiving one on-board the drone.…”

A near-field wireless power transfer (WPT) technology is applied to recharge the battery of a small size drone. The WPT technology is an extremely attractive solution to build an autonomous base station where the drone can land to wirelessly charge the battery without any human intervention. The innovative WPT design is based on the use of a mechanical part of the drone, i.e., landing gear, as a portion of the electrical circuit, i.e., onboard secondary coil. To this aim, the landing gear is made with an adequately shaped aluminum pipe that, after suitable modifications, performs both structural and electrical functions. The proposed innovative solution has a very small impact on the drone aerodynamics and the additional weight onboard the drone is very limited. Once the design of the secondary coil has been defined, the configuration of the WPT primary coil mounted in a ground base station is optimized to get a good electrical performance, i.e., high values of transferred power and efficiency. The WPT design guidelines of primary and secondary coils are given. Finally, a demonstrator of the WPT system for a lightweight drone is designed, built, and tested.

“…For example, in Xu et al, 19,20 the mechanisms for defining the optimal path for a drone featuring RF-based WPT were proposed. The real-life solutions for transferring the energy from a UAV to the sensors were instrumented and evaluated in-field in Chen et al 21 The practical drone-based simultaneous wireless power and information transfer (SWIPT) solution for battery-less sensors was reported in He et al 22 Finally, to the best of our knowledge, the combinations of WPT and LPWANs have been addressed by only a few studies. Danish et al 23 investigated how the in-band RF-based WPT toward LoRaWAN EDs affects the communication performance of the network.…”

Supported by the remarkable progress across many technological domains, the Internet of Things (IoT) ecosystem demonstrates steady growth over the few past years. This growth enables a number of new exciting applications. Nonetheless, hardly one can say today that the utility of the IoT is used to its full potential. This fact is especially notable for the monitoring applications deployed in remote areas. To address the needs of these use cases, in the article we propose a solution based on the combination of three key technologies: the low-power wide area networks, the unmanned aerial vehicles, and the wireless power transfer. In the article, we first detail the novel concept of a wireless power transfer-enabled unmanned aerial vehicle employed to charge the LoRaWAN sensor nodes. Then, via extensive simulations and analysis of an illustrative LoRaWAN application, we investigate both technical and, notably, business performance indicators, and compare them against the ones for a baseline scenario with no unmanned aerial vehicle. Our results illustratively demonstrate that in the long-term perspective, the inclusion of a wireless power transfer-enabled drone may drastically reduce the system's operating expenses. At the very same time, our results highlight the limits, bottlenecks, and trade-offs related to the proposed concept, thus providing the basis and calling for further investigation.

“…The main disadvantage is the complexity of the positioning system that could lead to reliability issues. Finally, a charging system based on radio frequency (RF) transmission was presented in [17]. This solution allows to improve the distance between transmitter and receiver but with a significant reduction of the efficiency and transferred power.…”

Wireless Power Transfer Technology Applied to an Autonomous Electric UAV with a Small Secondary Coil

This study deals with the design and the optimization of a wireless power transfer (WPT) charging system based on magnetic resonant coupling applied to an electric vertical take-off and landing Unmanned Aerial Vehicle (UAV). In this study, a procedure for primary and secondary coil design is proposed. The primary circuit in the ground station consists of an array of coils in order to mitigate the negative effects on the coupling factor produced by the possible misalignment between the coils due to an imperfect landing. Key aspects for the design of the secondary coil onboard the UAV are the lightness and compactness of the WPT system components. A demonstrative prototype of the WPT system is applied to a commercial drone. The WPT electrical performances are calculated and measured. Finally, an automatic battery recharge station is built where the drone can autonomously land, recharge the battery and take off to continue its flight mission.
