PROBLEM TO BE SOLVED: To provide a wireless power reception device and a wireless power transmission system which enable the efficient charging action by improving an activation response of a charging part in power supply during travel.SOLUTION: A wireless power reception device 200 is to be mounted on a movable body. The wireless power reception device comprises: a power reception part 210 operable to receive a power by wireless; a rectification part 220 operable to rectify a power received by the power reception part 210; a charging part 230 operable charge a power-storage part B0 with a power output by the rectification part 220; a capacitor part C1 connected between the rectification part 220 and the charging part 230, and charged with an output power of the rectification part 220; and a control part 240 operable to control a charging action of the charging part 230. The control part 240 causes the charging part 230 to start the charging action when a detection value based on a voltage arising in the power reception part 210 or a current passing through a detection value the power reception part 210 is equal to or larger than a reference value. When the detection value is under the reference value, the control part causes the charging part 230 to stop the charging action and supplies a power from the capacitor part C1 to the charging part 230.SELECTED DRAWING: Figure 1

    【課題】走行中給電において、充電部の起動レスポンスを向上させ、効率的な充電動作が可能なワイヤレス受電装置およびワイヤレス電力伝送システムを提供すること。【解決手段】移動体に搭載されるワイヤレス受電装置200であって、ワイヤレスにて電力を受電する受電部210と、受電部210が受電した電力を整流する整流部220と、整流部220が出力する電力を蓄電部B0に充電する充電部230と、整流部220と充電部230との間に接続され、整流部220の出力電力によって蓄電されるコンデンサ部C1と、充電部230の充電動作を制御する制御部240と、を備え、制御部240は、受電部210に生じた電圧または受電部210に流れる電流に基づく検出値が基準値以上のとき、充電部230の充電動作を開始させ、検出値が基準値を下回ったとき、充電部230の充電動作を停止させてコンデンサ部C1から充電部230に電力を供給する。【選択図】図1
