CONTACTLESS POWER TRANSMISSION DEVICE AND VEHICLE INCLUDING ITSELF, CONTACTLESS POWER TRANSMISSION DEVICE AND CONTACTLESS POWER TRANSMISSION SYSTEM

摘要

1. A contactless power receiving device configured to receive power transmitted from a power transmission device (100) in a contactless manner, comprising: a power receiving module (210, 220) configured to receive AC power transmitted from said device in a contactless manner power transmission at the first frequency; and - a communication device (290) configured to wirelessly communicate with said power transmission device via a radio wave having a second frequency, said first frequency and said second frequency being determined so that the relationship between said first frequency and said second frequency is non-integer multiple. 2. The non-contact power receiving device according to claim 1, wherein said power receiving module receives in a non-contact manner said AC power transmitted from a power transmission module (140, 150) in said power transmission device through resonance with said power transmission module through an electromagnetic field. 3. The contactless power receiving device according to claim 1 or 2, wherein said second frequency is defined above said first frequency. The contactless electric power receiving device according to claim 1 or 2, wherein said first frequency is determined based on a transmission state of said alternating current power, and said second frequency is determined so that the relationship between the determined first frequency and said second frequency is non-integer multiple. .
