PROBLEM TO BE SOLVED: To provide a non-contact power transmission and reception system, including a power reception apparatus which receives electric power from a power transmission apparatus in a non-contact manner and which is capable of charging a battery, that suppresses the power reception apparatus and peripheral apparatuses thereof from becoming relatively hot temperature while suppressing enlargement of the power reception apparatus or the like and increase in the number of parts.SOLUTION: A non-contact power transmission and reception system calculates a loss Plo as power difference between transmission power Ptr of a transmission unit of a power transmission apparatus and reception power Pre of a reception unit of a power reception apparatus (S130) and, when the calculated loss Plo is higher than a threshold value Ploref, a value smaller than a value when the loss Plo is not higher than the threshold value Ploref is set to target transmission power Ptr* (S140-S170) to control a high-frequency power supply circuit by using the target transmission power Ptr* (S180).SELECTED DRAWING: Figure 3

    【課題】送電装置から非接触で受電してバッテリを充電可能な受電装置を備えるものにおいて、受電装置などの大型化や部品点数の増加を抑制しつつ、受電装置やその周辺が比較的高温となるのを抑制する。【解決手段】送電装置の送電ユニットの送電電力Ptrと受電装置の受電ユニットの受電電力Preとの電力差として損失Ploを計算し(S130)、計算した損失Ploが閾値Plorefより大きいときには、損失Ploが閾値Ploref以下のときに比して小さな値を目標送電電力Ptr*に設定し(S140〜S170)、目標送電電力Ptr*を用いて高周波電源回路を制御する(S180)。【選択図】図3
