The results of a study of induction wireless charging methods for batteries of unmanned aerial vehicles (UAVs) are presented. An experimental simulation of energy transfer using inductive coupling has been carried out. The main factors influencing the efficiency of the system are determined: the distance between the coils, the accuracy of their alignment, and heat losses. It is shown that energy losses with increasing distance reach 45%, and when the coils are shifted by 3 cm, the transmission efficiency decreases by more than 45%. Recommendations have been developed to improve efficiency, including optimizing coil materials, increasing the frequency of energy transmission, automating coil alignment, and introducing active cooling. The results obtained form the basis for further improvement of UAV wireless charging systems.
