Title:
WIRELESS POWER FEEDING SYSTEM AND POSITION DETECTION METHOD OF POWER FEEDING COUPLER OF THE SAME
Document Type and Number:
Japanese Patent JP2019176590
Kind Code:
A
Abstract:
To provide a wireless power feeding system capable of detecting a position of a power feeding coupler based on electrical information of the power feeding coupler.SOLUTION: The wireless power feeding system includes: a power feeding coupler of an electric field resonance or magnetic field resonance type for wirelessly transmitting power from a power transmission coupler to a power reception coupler; a detection unit for measuring electrical information of at least one of the power transmission coupler or the power reception coupler; an estimation unit for estimating at least one of a relative position or a relative angle between the power transmission coupler and the power reception coupler based on a measurement result of the detection unit. The electrical information has an extreme value with respect to a change of the relative position or the relative angle between the power transmission coupler and the power reception coupler.SELECTED DRAWING: Figure 1
