With the fast development of magnetic coupling resonant-dynamic wireless power transfer (MCR-DWPT), it is more likely that high-efficiency wireless charging between unmanned ground vehicles (UGVs) will be practically realized, especially in desolate places that are far away from a city center or charging depot and always experiencing large load fluctuations, varying operating conditions, and complex working targets. Based on this, the wireless charging of UGVs demands higher reliability and efficiency. This paper reviews the MCR-DWPT system of UGVs, and the basic structure and key technologies are introduced. Then, the key technologies, which include the coupling device design, compensation topology design, and system control strategy, are discussed in detail. After that, by considering the current research, the main challenges of the MCR-DWPT of UGVs are investigated and its developing prospects are explored.

The agriculture sector has witnessed a transformation with the advent of smart sensing devices, leading to improved crop yield and quality. However, the management of data collection from numerous sensors across vast agricultural areas, as well as the associated charging requirements, presents significant challenges. This paper addresses the major research problem by proposing an innovative solution for charging agricultural sensors. The introduction of an energy-constrained device (ECD) enables wireless charging and transmission of soil data to a centralized server. The proposed ECDs will enable enhanced data collection, precision agriculture, optimized resource allocation, timely decision-making, and remote monitoring and control. A bidirectional wireless charging drone is employed to efficiently charge the ECDs. To optimize energy usage, a prioritized Dijkstra algorithm determines the ECDs to be charged and plans the shortest route for the drone. The wireless charging drone landing-charging station achieves an efficiency of 91.3%, delivering 72 W of power within a 5 mm range. Furthermore, the ECD possesses a data transmission range of 100 m and incorporates deep sleep functionality, allowing for a remarkable 30-day battery life.

“…However, in the event of relative motion between the transmitter and receiver, especially in the case of wireless charging between two traveling EVs, the transmitting coil and receiving coil are prone to be in random relative motion, causing the position between these two coils to randomly change. Such cases have been investigated by many scholars, showing that the relative position between the transmitting coil and receiving coil strongly affects the power level and transfer efficiency of the WPT [5][6][7]. Several works on WPT for EVs have been proposed.…”

This paper proposes a novel coupling structure wireless power transfer (WPT) technology for improving the charging and recharging efficiency between electric vehicles (EVs) in the case that the transmitting and receiving coils are not exactly aligned. During the process of wireless power transmission, if the relative position of the coils located on each objective is randomly changed, a change in the mutual inductance occurs, which critically leads to fluctuation in the WPT system output. In order to improve the tolerance of the EV WPT system, considering coupling structure misalignment and the deflection caused by relative location changes, a double-layer coupling structure with solenoid pads and double-D pads (SP-DDP coupling structure) is designed for deployment on the side of EVs. Then, the coupling structure is developed through parametrized optimization. Finally, the established coupling structure is evaluated through simulations and an experiment using a prototype, the results of which demonstrate that the proposed coupling structure can achieve good anti-misalignment and anti-deflection performance, realizing a system efficiency of 92.65% and an output power of 192.02 W for the designed EV WPT system.
