Title:

SYSTEM FOR CONTACTLESSLY SUPPLYING POWER TO MOVING BODY

Document Type and Number:

WIPO Patent Application WO/2012/121184

Kind Code:

A1

Abstract:

Provided is a system for contactlessly supplying power to a moving body, capable of detecting which direction the center axes of a power transmission side coil and a power reception side coil are shifted from each other and reducing the time required for controlling the alignment of the center axes of the coils. The magnetic field intensity distribution generated by the power transmission side coil is detected at multiple positions around the power reception side coil, and the positions of the power transmission side coil and the power reception side coil are adjusted so that the magnetic field intensity values at the multiple positions match each other.
