To provide a contactless electric power transmission system capable of performing appropriate power transmission by independent communication control and power control on the power reception side.SOLUTION: A contactless electric power transmission system 1 comprises an electric power reception device 4 and a controller 17. The electric power reception device 4 receives electric power transmitted contactlessly between itself and an electric power transmission device 2. In a coupling section in which a degree of coupling between a primary side coil of the electric power transmission device 2 and a secondary side coil of the electric power reception device 4 is equal to or larger than a predetermined degree, the controller 17 sets communication sections in which the degree of coupling is relatively small and electric power transmission sections in which the degree of coupling is relatively large. When the secondary side coil exists in the first communication section of the coupling section, the controller 17 transmits information on electric power transmission in the electric power transmission section from the electric power reception device 4 to the electric power transmission device 2 by using communication between the electric power transmission device 2 and the electric power reception device 4.SELECTED DRAWING: Figure 1

    【課題】受電側の独立的な通信制御及び電力制御によって適切な電力伝送を行うことができる非接触電力伝送システムを提供する。【解決手段】非接触電力伝送システム1は、受電装置4と、制御装置17とを備える。受電装置4は、送電装置2との間にて非接触で伝送される電力を授受する。制御装置17は、送電装置2の一次側コイルと受電装置4の二次側コイルとの結合度合いが所定以上である結合区間において、結合度合いが相対的に小さい通信区間と、結合度合いが相対的に大きい電力伝送区間とを設定する。制御装置17は、二次側コイルが結合区間の最初の通信区間に存在する場合に送電装置2と受電装置4との通信により、電力伝送区間での電力伝送に関する情報を受電装置4から送電装置2に送る。【選択図】図1
