ABSTRACT:
A power supply apparatus11and a storage device12that stores power supplied by the power supply apparatus11interpose a power supply control circuit10. The circuit has a charging current detector13to detect charging current IC flowing from the power supply apparatus11to the storage device12; a blocking unit15to interrupt the backflow current IR that flows from the storage device to the power supply apparatus on the basis of an inputted blocking control signal SH; and a backflow monitoring unit14to monitor by sampling for the presence of the charging current IC until the charging current IC is detected, constantly to monitor for the presence of the charging current IC after the charging current IC has been detected, and to output a blocking control signal SH for cutting off the backflow current IR when the charging current IC is not flowing.
