To detect an abnormality in a non-contact power supply system without providing any sensor in power transmission coils.SOLUTION: An abnormality detecting device 300 detects an abnormality in a non-contact power supply system including a plurality of power transmission units 100 having respective power transmission coils 112, and a vehicle 200 having a power reception coil 212 that receives power from the plurality of power transmission units 100. The abnormality detecting device includes an information reception unit 310 that receives power transmission unit information transmitted from each of the power transmission units 100 and vehicle power reception information transmitted from the vehicle 200, and a diagnosis executing unit 350 that identifies a plurality of power transmission units 100 having transmitted power to the vehicle 200 from current position information and current position acquisition time information about the vehicle 200 included in each of the plurality of received vehicle power reception information sets, and diagnoses an abnormality in a power transmission state of each of the power transmission units 100 by comparing power transmission amount information included in the power transmission unit information about the identified power transmission units 100.SELECTED DRAWING: Figure 1
【課題】各送電コイルにセンサを設けずに非接触給電システムの異常を検知する。【解決手段】それぞれが複数の送電コイル112を有する複数の送電ユニット100と、複数の送電ユニット100から電力を受電する受電コイル212を有する車両200とを備える非接触給電システムの異常を検知する異常検知装置300は、複数の送電ユニット100のそれぞれから送信される送電ユニット情報、及び、車両200から送信される車両受電情報を受信する情報受信部310と、受信した複数の車両受電情報のそれぞれに含まれる車両200の現在位置情報及び現在位置取得時刻情報から車両200に対して送電を行なった複数の送電ユニット100を特定し、特定した複数の送電ユニット100のそれぞれの送電ユニット情報に含まれる送電量情報を比較することで、複数の送電ユニット100のそれぞれについて、送電状態の異常を診断する診断実行部350と、を備える。【選択図】図1
