NON-CONTACT POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device capable of detecting foreign objects mixed into between a power transmission coil and a power reception coil.

SOLUTION: A non-contact power supply device includes: a second coil for transmitting or receiving an electric power to/from a first coil in non-contact fashion by means of at least magnetic coupling; a plurality of sensors for detecting displacement between the first coil and the second coil; position detection means for detecting relative position between the first coil and the second coil on the basis of each of the output values of the sensors; and foreign object detection means for comparing each of the output values of the sensors and detecting foreign objects between the first coil and the second coil on the basis of the comparison result.
