Title:
CONTACTLESS ELECTRICITY SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/157094
Kind Code:
A1
Abstract:
In this contactless electricity supply system, which provides power between the electricity transmission coil (11) of an electricity supply device (1) and the electricity reception coil (21) of a vehicle (2): the vehicle (2) is provided with a vehicle-side communication means, which transmits a permission signal that permits electricity transmission from the electricity transmission coil (11) to the electricity reception coil (21) with respect to one electricity supply device (1) among a plurality of electricity supply devices (1) and contains identification information for the one electricity supply device (1), a power detection means, which detects received power, and a determination means, which determines whether paired communication has been established between the vehicle (2) and the electricity supply device (1); the electricity supply device (1) is provided with an electricity-supply-device-side communication means, which receives the permission signal, and a control means, which causes the electricity transmission coil (11) to output power to the electricity reception coil (21); the control means outputs power from the electricity transmission coil (11) to the electricity reception coil (21) when the identification information of the electricity supply device (1) matches the identification information contained in the permission signal received by the electricity-supply-device-side communication means; and the determination means determines that paired communication has been established between the vehicle (2) and the one electricity supply device (1) when power has been detected by the power detection means.
