Design and Estimation Point Transfer for Dynamic Wireless Power Transfer Disc Coil for Electric Vehicle

One effort research topic in the electric vehicle is wireless power transfer (WPT). The advantage of using WPT is allowing the electric vehicle to charge while running (dynamic wireless power transfer). This is because, the transfer power method not involve a plug-in process. Therefore, in this research, an estimation of the number of transfers point from electric vehicles will be made to find the required electrical energy transfer for electric vehicles. In addition, the estimation is calculated in one hour based on the classification of the light and heavy electric vehicle power based on SAE J2954 standard. In this research, the disc coil is developed for transmitter and receiver, then it followed by creating a couple magnetic based on series-series topology method. The resonance frequency in this study is set to be constant at 100 kHz. Meanwhile, a constant gap between the transmitter and receiver is set to be 9 cm. To illustrate the dynamic movement of vehicle, e velocity and the distance of the electric vehicle are also set to be constant at 3.6 km/hour and 0.3 m. As a result, in the heavy electric vehicle, 22 kW and 200 kW to generate an electric vehicle in one hour are required 4,552,440 and 41,386,517 transfer points respectively. For the light electric vehicle with the size 3.7 kW, 7.7 kW and 11.1 kW need 765,600 1,593,333 and 2,296,667 transfer points respectively.
