Document Type and Number:
WIPO Patent Application WO/2015/102113
Kind Code:
A1
Abstract:
A wireless power transmission device equipped with: a power-feeding module that supplies electric power to a power-receiving module by causing a resonance phenomenon with the power-receiving module under a condition wherein a magnetic field space having a lower magnetic field intensity than the magnetic field intensity in the vicinity is formed; a magnetic field detector that is disposed at the position where the magnetic field space is formed and detects a magnetic field intensity; and a determination control instrument that determines an abnormality of the supplying of electric power to the power-receiving module on the basis of the value of the magnetic field intensity detected by the magnetic field detector.
