Title:
NON-CONTACT ELECTRICAL TRANSMISSION AND RECEPTION SYSTEM, VEHICLE, AND ELECTRICAL TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/088488
Kind Code:
A1
Abstract:
This non-contact electrical transmission and reception system is provided on an electrical transmission device (200A or 200B) and equipped with: a transmitter (220) for transmitting power to a vehicle without contact; a receptor (110) provided to the vehicle, for receiving power from the transmitter (220) without contact; and a control device (240, 300) for controlling the transmitter (220) and/or the receptor (110). The control device (240, 300) performs control so that power is transmitted and received if the reception efficiency of the receptor for electric power transmitted from the transmitter (220) is greater than a threshold value. This threshold value is able to be variably set by the control device (240, 300). Preferably, the control device sets the threshold value at the higher value between a first threshold value determined in accordance with the transmitter device and a second threshold value determined in accordance with the vehicle.
