Title:
NON-CONTACT POWER RECEPTION DEVICE, VEHICLE COMPRISING SAME, NON-CONTACT POWER TRANSMISSION DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/164744
Kind Code:
A1
Abstract:
AC power for a power transmission frequency (f1) is transmitted from a resonance coil (140) in a power transmission device (100) to a resonance coil (210) in a power reception device (200). In addition, communications occur between a communications device (170) for the power transmission device and a communications device (290) for the power reception device, using wireless radio waves of a communications frequency (f2). The power transmission frequency (f1) and the communications frequency (f2) are determined here such that that relationship between the power transmission frequency (f1) and the communications frequency (f2) is a non-integer factor.
