Title:
NON-CONTACT POWER TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2018174691
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact power transmission system capable of more exactly positioning a primary coil and a secondary coil.SOLUTION: A vertical distance estimation unit 62 estimates a vertical distance Z to the centers of a primary coil 28 and a secondary coil 44 on the basis of a voltage value V_LPE detected by a voltage detector 50. A horizontal distance estimation unit 64 estimates a horizontal distance D between the centers of the primary coil 28 and the secondary coil 44 on the basis of the vertical distance Z estimated by the vertical distance estimation unit 62, the voltage value V_LPE detected by the voltage detector 50 and voltage value-distance information stored in a memory 66.SELECTED DRAWING: Figure 1
