Abstract :
Move-and-charge technology is an emerging technology for the Electric vehicle (EV) charging. It can charge the EV wirelessly even when the EV is in motion. Therefore, the short driving range and long charging time of EVs can be satisfactorily solved. In this paper, two main move-and-charge technologies, namely the inductive power transfer (IPT) and the magnetic resonance coupling (MRC), are quantitatively analyzed and compared. By using 3-D finite element method and the equivalent circuit models, the magnetic modeling of IPT and MRC systems are established. Based on magnetic models of the two systems, the output power of primary side/transmitter, received power of secondary side/receiver, transmission characteristics and efficiencies at different situations, especially for the misalignment conditions, are obtained. Finally, based on the transmission performances, two technologies are discussed and summarized.
