NON-CONTACT POWER FEEDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power feeding device that detects a foreign matter above the coil axis direction of a power transmission coil.SOLUTION: The non-contact power feeding device includes: a power transmission coil 12 provided on the ground for transmitting electric power in a non-contact manner by magnetic coupling at least to a power reception coil 22 provided in a vehicle; a foreign matter detection coil 13 disposed above the coil axis direction of the power transmission coil 12. The foreign matter detection coil 13 detects foreign matter above the coil axis direction of the power transmission coil 12 on the basis of a change in an induction voltage caused by a change in magnetic flux above the coil axis direction of the power transmission coil 12.SELECTED DRAWING: Figure 2
