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 the response of a charging action of a charging part in charge during travel.SOLUTION: A wireless power reception device 200 is to be mounted on a movable body. The wireless power reception device 200 comprises: a power reception inductor 211 and an auxiliary power reception inductor 221 which receive a power through a magnetic field; a rectification part 240 operable to rectify a power received by the power reception inductor 211 and the auxiliary power reception inductor 221; and a charging part 250 connected with the rectification part 240, and charging a power-storage part 320 mounted on a movable body 500. The auxiliary power reception inductor 221 is located ahead of the power reception inductor 211 in a progressive direction of the movable body 500. The amount of power that the auxiliary power reception inductor 221 receives per unit time is smaller than the amount of power that the power reception inductor 211 receives per unit time. The charging part 250 starts the activation by a power received by the auxiliary power reception inductor 221.SELECTED DRAWING: Figure 1

    【課題】走行中充電において、充電部の充電動作の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】ワイヤレス受電装置200は、移動体に搭載されるワイヤレス受電装置200であって、磁界を介して電力を受電する受電コイル211および補助受電コイル221と、受電コイル211および補助受電コイル221が受電した電力を整流する整流部240と、整流部240に接続され、移動体500に搭載される蓄電部320を充電する充電部250と、を備え、補助受電コイル221は、受電コイル211よりも移動体500の進行方向前側に位置し、補助受電コイル221の単位時間当たりに受電する電力量は、受電コイル211の単位時間当たりに受電する電力量よりも小さく、充電部250は、補助受電コイル221が受電した電力によって起動を開始する。【選択図】図1
