To provide a relay failure detection system that enables charging to be started or ended accurately at a date and time desired by a user.SOLUTION: In a relay failure detection system housed in charging equipment for an electric vehicle and mounted on a power switching module, a relay is arranged in a power switching module on a power line between the AC input and the outlet output to the electric vehicle, and the relay failure detection system includes a conversion unit that switches between outputting a HIGH signal or a LOW signal when the absolute value of the relay output that is output to the outlet output is greater than or equal to a predetermined threshold value or less than the threshold value depending on the open/closed state of the relay, and a determination unit that determines whether the operation of the relay is normal or abnormal on the basis of an opening/closing command signal to the relay and the output signal of the conversion unit.SELECTED DRAWING: Figure 3

    【課題】ユーザの所望の日時において正確に充電を開始または終了することを可能とするリレー故障検知システムを提供する。【解決手段】電動移動体用の充電設備内に収納され、電力開閉モジュールに搭載されるリレー故障検知システムにおいて、リレーは、電力開閉モジュールにおいて、交流入力と、電動移動体へのコンセント出力の間の電力線に配置され、リレー故障検知システムは、リレーの開閉状態に応じてコンセント出力に出力されるリレー出力の絶対値が所定の閾値以上の場合と、閾値未満の場合とで、HIGH信号とLОW信号を切り替えて出力する変換部と、リレーへの開閉指令信号と、変換部の出力信号とに基づいて、リレーの動作の正常と異常とを判定する判定部と、を備える。【選択図】図3
