PROBLEM TO BE SOLVED: To detect an abnormality in a vehicle charge cable as early as possible.SOLUTION: An abnormality detection device detects an abnormality in a vehicle charge cable for supplying power from a power feeder on the outside to an electric vehicle. The abnormality detection device includes: an electrostatic capacitance measurement section for obtaining a measurement value corresponding to an electrostatic capacitance between the core wires of at least two electric wires among multiple electric wires of the vehicle charge cable; and an abnormality detection control section for determining existence of an abnormality in the vehicle charge cable on the basis of the measurement value obtained by the electrostatic capacitance measurement section.
【課題】車両用充電ケーブルの異常をなるべく早期に検知できるようにすることを目的とする。【解決手段】異常検知装置は、外部の給電装置から電動車両に向けて電力を供給するための車両用充電ケーブルの異常を検知する。異常検知装置は、車両用充電ケーブルの複数の電線のうち少なくとも2つの電線の芯線間の静電容量に応じた測定値を求める静電容量測定部と、静電容量測定部によって求められた測定値に基づいて車両用充電ケーブルの異常の有無を判定する異常検知制御部と、を備える。【選択図】図2
