This article introduces the reader to wireless charging comes alive for more than a hundred years, the beginning of the Tesla transformer, and today it is actually used by small electronics to charge electric vehicles (EV). Wireless Charging Station (WCS) is based on inductive power transmission (IPT) of electrical energy. The station is divided into a docking station and a charger. Includes a coil for a transmitting coil operating up to 108 kHz, a circular spiral coil on the receiving and transmitting side, rectifier with step-down converter and controllers. Efficiency of Wireless power transfer (WPT) will be calculated. The magnetic field of the coils is simulated using the CST simulation program specifically in the CST EM studio. This behavior of field is shown for different coil positions. Wireless modules communicate in the ISM band with GFSK modulation, and are used for voltage and current monitoring in the charger, which can determine the insufficient position of the coils. This is also a way to enable accurate landing for unmanned aerial vehicles (UAV) instead of landing with camera and quick response (QR) code detection. Nevertheless for precise guidance UAV towards station is necessary global position system (GPS). A minor problem occurs with the transferring energy, between coils is generated by an electromagnetic field (EMF), which needs to be eliminated due to electromagnetic interference (EMI). This may adversely affect the guidance and information systems and a serious error may occur in the electronic system. The station design is designed to charge low voltage and low power devices such as Separated Extra Low Voltage (SELV).
