“…The results confirm that the wireless power transfer distance in the seawater environment is more than 10 meters. [18] confirms underwater WPT over 10 meters through multi-coil experiments. The above researches are all methods to improve transfer efficiency and increase transfer distance by different methods at present, and certain achievements have achieved, however, these two issues cannot be resolved simultaneously.…”

In this work, particular and general solutions to Airy’s inhomogeneous equation are obtained when the forcing function is one of Airy’s functions of the first and second kind, and the standard Nield-Kuznetsov function of the first kind. Particular solutions give rise to special integrals that involve products of Airy’s and Nield-Kuznetsov functions. Evaluation of the resulting integrals is facilitated by expressing their integrands in asymptotic series. Corresponding expressions for the Nield-Kuznetsov function of the second kind are obtained.

“…e system transmission efficiency is 50%, and it is found that eddy current loss is the main form of energy loss [17]. Not only does the eddy current loss exist in the marine but also the huge water pressure, ocean current disturbance, seawater composition, and water temperature in the deep sea will affect the performance of the wireless power transmission.…”

ICPT is one of the most influential solutions in the field of wireless power transmission, but it is also very susceptible to the working environment. The complicated marine environment has a great influence on the performance of ICPT. In the deep-sea high-pressure environment, due to the piezomagnetic effect, the magnetic core in the coupling structure will suddenly change the permeability, and the coupling coefficient, self-inductance, and other parameters will also change accordingly. At the same time, changes in ocean currents in the ocean will cause the ICPT coils to be misaligned, thereby affecting the magnetic field distribution between the coils and the transmission efficiency of the system. In order to provide theoretical support for optimum design of ICPT system in ocean environment, the influence of core performance changes and ICPT coil misalignment on system transmission efficiency is studied.

“…However, wireless charging with high power should take certain safety measures into consideration, e.g., protecting human bodies from radiation exposure. Recently, a company named LaserMotive successfully beamed a 17.5pound drone and kept it airborne for at least 48 h (i.e., about 46 h longer than a conventional drone), and that research is ongoing with the aim of expanding to applications for fighter jets [102], [103]. However, these far-field charging technologies cannot achieve maximum power utility.…”

The increasing emissions created by the large-scaled number of automobiles around the world pose severe threats to modern life by causing global warming issues and deteriorating air quality. These serious issues stimulate the essential demand for cleaner, safer, and more efficient vehicles, such as battery electric vehicles (BEVs). Unlike other studies on the charging technologies of BEVs, this paper gives a comprehensive state-of-the-art review on the charging technologies available for BEVs: wired charging and wireless charging technologies. First, the wired charging technologies are systematically classified into AC charging (indirect charging) and DC charging (direct charging) methods based on how the BEVs batteries are fed from the grid. Next, the configurations and commonly used topologies of wireless charging technologies for BEVs are thoroughly discussed. The leading institutes/companies driving advancements in both technologies are also acknowledged. Finally, this paper extensively highlights the recent and future research trends along with the industrial applications. INDEX TERMS AC charging, battery electric vehicles (BEVs), DC charging, off-board charger, on-board charger (OBC), wired charging, wireless charging.
