Abstract: In an in-motion power supply system with a plurality of power supply segments to supply power to a vehicle, a vehicle position detection unit detects a position of the vehicle relative to each segment. An electrical characteristic acquisition unit acquires electrical characteristics in the segment involved in power transfer, and an abnormality determination unit uses the electrical characteristics to determine whether there is an abnormality in the segment involved in power transfer. The abnormality determination unit shares the electrical characteristics between a subject segment subjected to abnormality determination and at least one of a previous segment previous to the subject segment and a subsequent segment subsequent to the subject segment, and compares the electrical characteristics in the subject segment with at least either the electrical characteristics in the previous segment or the electrical characteristics in the subsequent segment to determine whether the electrical characteristics in the subject segment are abnormal.

Abstract: A contactless power supply system is provided for supplying electric power to a vehicle in a contactless manner during traveling of the vehicle. The contactless power supply system includes a plurality of primary coils installed along a traveling direction in a road and a secondary coil mounted to the vehicle. Each of the primary coils is a single-phase coil with the secondary coil being a multi-phase coil, or is a multi-phase coil with the secondary coil being a single-phase coil.
