A ground fault detection device (10) is used in an in-vehicle system (100). An in-vehicle system (100) is provided with a power supply unit (90), a power storage unit (91), a conductive path (80), and a cutoff unit (74). The conductive path (80) has a first conductive path (81), a second conductive path (82), and a third conductive path (83). The cutting section (74) has a first cutting section (75) and a second cutting section (76). The second load (72) is connected to one of the second conductive path (82) and the third conductive path (83), and the third load (73) is connected to the other of the second conductive path (82) and the third conductive path (83). The grounding detection device (10) is provided with a detection unit (a current detection unit (13) and a control circuit (14)) for detecting grounding of at least one of the second conductive path (82) and the third conductive path (83).

    接地检测装置(10)在车载系统(100)中使用。车载系统(100)具备电源部(90)、蓄电部(91)、导电路(80)和切断部(74)。导电路(80)具有第一导电路(81)、第二导电路(82)和第三导电路(83)。切断部(74)具有第一切断部(75)和第二切断部(76)。将第二负载(72)连接于第二导电路(82)和第三导电路(83)中的一方的路径,将第三负载(73)连接于另一方的路径。接地检测装置(10)具有检测第二导电路(82)和第三导电路(83)中的至少一方的接地的检测部(电流检测部(13)和控制电路(14))。
