PROBLEM TO BE SOLVED: To provide an electric power management device and an abnormality detection method for detecting an abnormality of a switch that connects a secondary battery with a vehicle.SOLUTION: A power supply management device 16 provided in a vehicle mounted with an engine and a secondary battery 13 includes: a communication section 21 for acquiring control information on the vehicle; a switch section 18 for opening/closing an electric power supply line for supplying output electric power from the secondary battery 13 to the vehicle; an electric current detection section 20 for detecting an electric current flowing in the electric power supply line; and a control section 23. When detecting starting of the engine on the basis of the control information acquired by the communication section 21, the control section 23 performs control to switch the switch section 18 to a closed state, determines whether or not an absolute value of the electric current detected by the electric current detection section 20 is less than a threshold value, and determines opening fixation of the switch section 18 when the absolute value of the electric current is less than the threshold value.SELECTED DRAWING: Figure 1
【課題】二次電池と車両とを連結するスイッチの異常を検出する電力管理装置及び異常検出方法を提供する。【解決手段】エンジン及び二次電池13が搭載された車両に備えられる電源管理装置16であって、車両の制御情報を取得する通信部21と、二次電池13の出力電力を車両に供給するための電力供給線を開閉するスイッチ部18と、電力供給線を流れる電流を検出する電流検出部20と、制御部23と、を備える。制御部23は、通信部21が取得した制御情報に基づいてエンジンの始動を検出した場合、スイッチ部18を閉状態に切り替えるように制御し、電流検出部20が検出した電流の絶対値が閾値未満であるか否か判定し、電流の絶対値が閾値未満である場合、スイッチ部18の開固着と判定する。【選択図】図1
