The invention provides a fault diagnosis method for a current interrupting device and a power storage device. A fault diagnosis method for a current interruption device (21A) provided in a power supply system (12) of a vehicle (1) includes: a supply step in which a power supply device (14) supplies power to a first electrical load (11) and a first power storage device (13); an instruction step for instructing the current interruption device (21A) to interrupt in a state in which power is supplied from the power supply device (14) to the first electrical load (11) and the first power storage device (13); and a determination step in which the charging current of the secondary battery (20A) is measured by the current sensor (21B) in a state in which the current interruption device (21A) is instructed to be interrupted, and the presence or absence of a failure in the current interruption device (21A) is determined on the basis of the measured current value.

    本发明提供一种电流切断装置的故障诊断方法以及蓄电装置。车辆(1)的电源系统(12)具备的电流切断装置(21A)的故障诊断方法包括:供给步骤,电力供给装置(14)向第1电气负载(11)以及第1蓄电装置(13)进行电力供给;指示步骤,在从电力供给装置(14)向第1电气负载(11)以及第1蓄电装置(13)进行电力供给的状态下,向电流切断装置(21A)指示切断;和判断步骤,在向电流切断装置(21A)指示了切断的状态下,由电流传感器(21B)测量二次电池(20A)的充电电流,基于测量出的电流值来判断电流切断装置(21A)有无故障。
