Abstract: A power supply system includes a storage battery and first and second current sensors for detecting electric current flowing to the storage battery. The second current sensor has a wider current detection range than the first current sensor. A storage battery control apparatus includes: an abnormality determination unit that determines whether an abnormality has occurred in the first current sensor; a first charging control unit that performs, when no abnormality has occurred in the first current sensor, a charging completion determination based on the electric current detected by the first current sensor; and a second charging control unit that performs, when an abnormality has occurred in the first current sensor, the charging completion determination based on the electric current detected by the second current sensor. The first charging control unit and the second charging control unit have different determination criteria for determining completion of the charging of the storage battery.
