Radio waves are managed in the world that frequencies can be used effectively and mainly in telecommunications, which are a limited resource. Since Wireless Power Transfer (WPT) transmits power in the air using electromagnetic fields, a WPT system interference with telecommunications equipment and other devices. This report investigates the electromagnetic environmental effects of the DWPT system. Two types of electromagnetic field evaluations were conducted to ensure that the system does not affect other electrical equipment (Electro-Magnetic Compatibility: EMC), and the human body (Electro-Magnetic Force: EMF). The results of the EMC evaluation indicate to keep the EMC limits even when 50 kW of power is transmitted per vehicle. The maximum value of EMF estimates within the EMF reference even when 25 kW of power is transmitted per coil by placing near a wheel.
