Contactless electric power transfer device, contactless electric power receiving device, and contactless electric power receiving system

摘要

A contactless power transmission device capable of transmitting contactless power to a power receiving device (100), the contactless power transmission device comprising: a power transmission unit (220) configured to be able to transmit contactless power to the power receiving device (100); and characterized by: a communication unit (230) configured to send, before the power transmission unit (220) begins to transmit power to the power receiving device (100), information, which refers to a distribution of magnetic flux of the power transmission unit (220) during power transmission, to the power receiving device (100), to identify the compatibility of the power transmission unit (220) and the receiving device (100) of power
