| Popis: | Electric vehicles (EV) are expected to solve the environmental problems, since high-efficiency operation without CO2 and NOx emissions. In order to create a charging infrastructure by installing equipment in such as locations as carports in private homes, the wireless battery charging system is very suitable. Furthermore, the wireless EV charger is suitable for autonomous vehicles and is expected to contribute to the spread of electric vehicles. However, misalignment between the power feeding and the power receiving coils causes decreases in transmission power and efficiency. In this paper, proposed is a new method of position detection by analyzing voltage difference of search coils which can obtain the required accuracy with a simple configuration. |
