Wireless power transfer (WPT) technologies have now reached a commercial stage in applications going from consumer electronics, biomedical implants and domestic applications. For electrical cars, WPT offers some new opportunities compared to classical wired charging. Although there exist some commercial cars equipped with wireless charging system, improving design procedures needs to address various domains including power electronics, components and electromagnetics. The magnetic coupling system is a key component of wireless power transfer: the coils and surrounding materials have a great impact on the efficiency of the transfer as well as the level of the stray field near the system. The paper aims to present three essential features regarding the inductive power transfer dedicated to electric vehicles. The first one addresses the topology and efficiency of the coupling system, the second one underlines the human exposure considerations and the third one deals with the impact of uncertainties regarding system parameters.
