Document Type and Number:
Japanese Patent JP2020010491
Kind Code:
A
Abstract:
To provide a non-contact power transmission system capable of detecting a phase coil angle at high accuracy using an imaging device in alignment of a primary coil and a secondary coil.SOLUTION: A non-contact power transmission system 10 comprises: a power transmission unit 100 containing a primary coil 101; and a power reception unit 200 containing a secondary coil 201. Power transmission is performed from the primary coil of the power transmission unit to the secondary coil to the power reception unit in a non-contact manner. At least one of the power transmission unit and the power reception unit includes at least one of an imaging device and a linear light emitter and two or more point-shaped light emitters. The non-contact power transmission system further comprises a correction unit (a power transmission ECU 150) that recognizes at least one of a line formed by the linear light emitter and the line connecting the two or more point-shaped light emitters by using the imaging device, and corrects a deviation of an attachment angle of the imaging device using the line recognized by the imaging device.SELECTED DRAWING: Figure 1
