To provide a power reception device, a power transmission device, and a power transmission and reception device which can reliably transmit a required amount of power in a non-contact manner while having a degree of freedom in movement of a mobile body.SOLUTION: According to an embodiment, a power reception device includes: a first power reception coil; a second power reception coil; and a power reception circuit. The first power reception coil is provided at a position where power acquired from the first transmission coil increases when a position of a cart deviates in a first direction from a reference position. The second power reception coil is provided at a position where power received from the second power transmission coil installed at a position different from the first power transmission coil decreases when the position of the cart deviates in the first direction from the reference position. The power reception circuit outputs the power received by the first and second power reception coils.SELECTED DRAWING: Figure 1

    【課題】 移動体の移動に自由度が持たせながらも必要な電力量を確実に非接触で伝送できる受電装置、送電装置および送受電システムを提供する。【解決手段】 実施形態によれば、受電装置は、第1の受電コイルと、第2の受電コイルと、受電回路と、を有する。第1の受電コイルは、カートの位置が基準位置から第1の方向にずれると第1の送電コイルから取得する電力が増加する位置に設ける。第2の受電コイルは、カートの位置が基準位置から第1の方向にずれると第1の送電コイルとは異なる位置に設置した第2の送電コイルから受電する電力が減少する位置に設ける。受電回路は、第1の受電コイルと第2の受電コイルとが受電する電力を出力する。【選択図】図1
