PROBLEM TO BE SOLVED: To provide a power transmission apparatus transmitting electric power to a power reception apparatus in a non-contact manner and a power transmission system having the same, capable of avoiding continuous power transmission under such a condition that foreign matter has been detected.SOLUTION: A power reception apparatus 10 is configured so that a charging ECU 500 detects foreign matters included between a power reception unit 100 and a power transmission unit 700, using a camera 510. A communication unit 520 transmits a communication state determination signal for determining a communication state between communication units 520, 810 to the communication unit 810 by making variations at a shorter interval than a predetermined time regardless of a detection result of a foreign matter. A power transmission apparatus 20 is configured so that a power supply ECU 800 controls a power supply unit 600 to stop power supply from the power supply unit 600 to the power transmission unit 700 when a communication state determination signal does not vary for over the predetermined time.SELECTED DRAWING: Figure 1

    【課題】受電装置へ非接触で送電する送電装置及びそれを備える電力伝送システムにおいて、異物が検知されているにも拘わらず送電が継続されるのを回避する。【解決手段】受電装置10において、充電ECU500は、カメラ510を用いて、受電部100と送電部700との間に介在する異物を検知する。通信部520は、異物の検知結果に拘わらず、所定時間よりも短い時間間隔で変動することによって通信部520,810間の通信状態を判定するための通信状態判定信号を通信部810へ送信する。送電装置20において、電源ECU800は、通信状態判定信号が所定時間以上変動しない場合に、電源部600から送電部700への電力供給を停止するように電源部600を制御する。【選択図】図1
