PROBLEM TO BE SOLVED: To provide a power receiving device for a vehicle capable of appropriately charging a battery even when a communication abnormality occurs between a power supply unit and a power receiving unit.SOLUTION: A power receiving device for a vehicle includes: a power receiving unit 11 that receives power from a power feeding unit F installed in a power feeding lane LS; a requested power supply amount determination section 12 that determines a power supply amount requested from the power receiving unit 11 side to the power feeding unit F; and a difference calculation section 13 that calculates a difference power supply amount Γ obtained by subtracting the power supply amount determined by the requested power supply amount determination section 12 from a power transmission amount actually transmitted from the power feeding unit F to the power receiving unit 11, in which, when a communication abnormality occurs between the two units F, 11, the difference calculation section 13 calculates the difference power supply amount Γ while this communication abnormality occurs, and when the communication state returns to a normal state, the requested power supply amount determination section 12 corrects the required power supply amount determined based on the power supply amount necessary for driving the vehicle 1 by increasing or decreasing the correction value based on the difference power supply amount Γ and calculates the required power supply amount.SELECTED DRAWING: Figure 1
【課題】給電ユニットと受電ユニットとの間で通信異常が生じたときにおいても、バッテリを適切に充電することができる車両用受電装置を提供する。【解決手段】給電レーンLSに設置された給電ユニットFから受電する受電ユニット11と、受電ユニット11側から給電ユニットFに対して要求する給電量を決定する要求給電量決定部12と、給電ユニットFから受電ユニット11に実際に送電された送電量から、要求給電量決定部12によって決定された給電量を引いた差分給電量Γを算出する差分算出部13と、を備え、両ユニットF、11間に通信異常が生じた際に、差分算出部13が、この通信異常が生じている間の差分給電量Γを算出し、通信状態が正常に戻った際に、要求給電量決定部12が、その差分給電量Γに基づいて、車両1の駆動に必要な給電量に基づいて決定された要求給電量を増減補正した補正要求給電量を算出する車両用受電装置を構成する。【選択図】図1
