Title:

NON-CONTACT ELECTRIC POWER TRANSFER DEVICE, NON-CONTACT ELECTRIC POWER RECEPTION DEVICE, AND NON-CONTACT ELECTRIC POWER RECEPTION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2013/124977

Kind Code:

A1

Abstract:

A non-contact electric power transfer device is capable of transferring electric power to an electric power reception device (100) without contact, and is provided with an electric power transfer unit (220) configured to be capable of transferring electric power to the electric power reception device without contact, and a communication part (230) for transmitting, to the electric power reception device, information relating to a magnetic flux distribution of the electric power transfer unit during transfer of electric power. Preferably, this information is used to determine whether the electric power reception device (100) is to receive electric power from the non-contact electric power transfer device (200). More preferably, the communication part (230) transmits information before the electric power transfer unit (220) begins transferring electric power to the electric power reception device (100).
