<p><P>PROBLEM TO BE SOLVED: To provide a power supply controller equipped with a main power supply and a power supply for supplying power to other apparatuses, which complements, when a main power supply is turned on after turned off, electric power information for the time from when the electric power information is stored in a non-volatile storage medium to when the main power supply is turned on. <P>SOLUTION: The power supply controller which includes a power supply 22 for supplying power to a power port, and prevents power supplied to other apparatuses from being interrupted even when a main power supply 30 is disconnected, includes: a measurement unit 26 that measures electric power information on electric power supplied to other apparatuses; a storage control unit that stores the measured electric power information and measurement time in an SDRAM 12, and stores the electric power information and the measurement time stored in the SDRAM in a flash ROM 14 in a desired timing; and a complementing unit that, when a main power supply is turned on after turned off, stores to the SDRAM the complementary electric power information assumed to be supplied to the other apparatuses between the last measurement time stored in the flash ROAM and the time when the main power supply is turned on, and the time corresponding thereto. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
