To resume a power transmission while reducing the power consumption of a power receiving device when the power transmission from a power transmitting device is stopped due to the abnormality of the power transmitting device in a non-contact power transmission system in which an electric power is transmitted non-contact from the power transmitting device to the power receiving device.SOLUTION: A non-contact power transmission system comprises a power transmitting device and a power receiving device. The power transmitting device stops a power transmission when an abnormality of the power transmitting device occurs during the power transmission to the power receiving device. The power receiving device is shifted to a sleep state having a lower power consumption than that of an operational state when the power transmission is stopped. The power receiving device automatically starts and transmits a request for resuming the power transmission to the power transmitting device when a first sleep time elapses after being shifted to the sleep state. The power transmitting device resumes the power transmission on the trigger of the request for resuming the power transmission from the power receiving device when the power transmission is stopped due to the abnormality of the power transmitting device.SELECTED DRAWING: Figure 3

    【課題】送電装置から受電装置へ非接触で電力を伝送する非接触電力伝送システムにおいて、送電装置の異常によって送電装置が送電を停止した場合に、受電装置の消費電力を抑制しつつ、送電を再開させる。【解決手段】非接触電力伝送システムは、送電装置と、受電装置とを備える。送電装置は、受電装置への送電中に送電装置の異常が生じた場合、送電を停止する。受電装置は、送電が停止された場合、作動状態よりも消費電力の小さいスリープ状態に遷移する。受電装置は、スリープ状態に遷移してから第1スリープ時間が経過した場合に自動的に起動して送電装置に送電再開要求を送信する。送電装置は、送電装置の異常によって送電を停止している場合、受電装置からの送電再開要求を受信したことをトリガーとして送電を再開する。【選択図】図3
