The use of electric vehicles in the world is increasing from year to year. However, electric vehicles have several drawbacks, one of which is that the charging time for electric vehicles is much longer than refueling the Internal Combustion Engine Vehicles (ICEV). One solution to this problem is by charging electric vehicles while the vehicles are moving. The charging or power transfer method that can be applied is EV Moving Wireless Charging using the Wireless Power Transfer (WPT) method. The Wireless Power Transfer method that will be used in this study is the Inductive Power Transfer (IPT) system. The designed WPT system consists of an AC Voltage Source, Transmitter Rectifier, Inverter, LCC Compensation Circuit, Transmitter Coil arrangement, Receiver Coil, Receiver Rectifier, and battery load. From the overall circuit simulation results, an efficiency of around 70% is obtained for each coil pair. The static charging tests carried out are testing the whole system, experimenting with a signal generator, lateral and longitudinal misalignment, testing the air-gap variation, and testing the frequency variation. The dynamic charging test that is carried out is tested by varying the distance between the coils. The results of testing the system as a whole have not been able to produce the maximum power output. While experimenting with a signal generator produces an efficiency of 87%, namely on transmitter coil 1. Meanwhile, lateral and longitudinal misalignment tests obtain maximum efficiency when they are in the perfect misalignment position. Furthermore, for air gap and frequency variations, maximum efficiency is obtained according to the design that was designed, namely at 20 mm and 100 kHz. In the last test related to dynamic charging, the most optimal results were obtained when the distance between the coils was 2 cm with an efficiency of 10.02%.
