Inductive Coupling Characteristics of Nano-Crystalline Alloy for Electric Vehicle PLC

In this paper, we presents the characteristics of an inductive coupling unit (ICU) made of a nano-crystalline alloy for contactless electric vehicle power line communication (EV PLC). An ICU contains a toroidal transformer consisting of a circular nanocrystalline core and two wires sharing a magnetic field caused by an electric signal. An average channel bandwidth of 48 Mbps was measured when the proposed ICUs were installed on the high power line between EV and EV charger. EV PLC using a miniaturized nano-crystalline ICU will contribute to simplification and weight reduction of electric vehicle wiring.
