The power supply system includes a first current sensor (22) having a first range as a current detection range, and a second current sensor (23) having a second range wider than the first range as a current detection range, as current sensors for detecting a current flowing through a storage battery (21). The battery control device (70) is provided with: an abnormality determination unit that determines whether or not an abnormality has occurred in the first current sensor; a first charging control unit that, when it is determined that there is no abnormality in the first current sensor, performs charging completion determination on the basis of the current detected by the first current sensor; and a second charging control unit that, when it is determined that an abnormality has occurred in the first current sensor, uses the second current sensor instead of the first current sensor, and performs the charging completion determination on the basis of the current detected by the second current sensor. In addition, the first charging control unit and the second charging control unit are different from each other in terms of determination criteria for performing the charging completion determination.
电源系统包括将第一范围设为电流检测范围的第一电流传感器(22)和将比上述第一范围宽的第二范围设为电流检测范围的第二电流传感器(23),以作为对流过蓄电池(21)的电流进行检测的电流传感器。蓄电池控制装置(70)包括:异常判定部,其判定上述第一电流传感器是否发生异常;第一充电控制部,其在判定为上述第一电流传感器未发生异常时,基于第一电流传感器的检测电流实施充电完成判定;以及第二充电控制部,其在判定为上述第一电流传感器发生了异常时,使用上述第二电流传感器代替上述第一电流传感器,基于该第二电流传感器的检测电流实施上述充电完成判定。另外,在上述第一充电控制部和上述第二充电控制部中实施上述充电完成判定的判定基准各不相同。
