Abstract

A power supply controlling apparatus including: a measurement portion that measures electric power information concerning electric power supplied to another apparatus, a storing control portion that stores the electric power information measured by the measurement portion and measurement time when the electric power information is measured, into a volatile storage, and stores the electric power information and the measurement time stored into the volatile storage, into a nonvolatile storage in desired timing; and a supplement portion that, when a first power supply is turned off and turned on again, supplements to the volatile storage electric power information and time concerning electric power assumed to be supplied to the another apparatus between final measurement time in a plurality of pieces of measurement time stored in the nonvolatile storage and time when the first power supply is turned on again.

Claims

1. A power supply controlling apparatus comprising:

a first power supply that supplies electric power to another apparatus;

a second power supply that supplies electric power to the another apparatus even when the first power supply is turned off;

a measurement portion that measures electric power information concerning electric power supplied to the another apparatus;

a storing control portion that stores the electric power information measured by the measurement portion and measurement time when the electric power information is measured, into a volatile storage, and stores the electric power information and the measurement time stored into the volatile storage, into a nonvolatile storage in desired timing; and

a supplement portion that, when the first power supply is turned off and turned on again, supplements to the volatile storage electric power information and time concerning electric power assumed to be supplied to the another apparatus between final measurement time in a plurality of pieces of measurement time stored in the nonvolatile storage and time when the first power supply is turned on again.

2. The power supply controlling apparatus according to claim 1, wherein the supplement portion supplements electric power information measured immediately after the first power supply is turned on again, to the volatile storage.

3. The power supply controlling apparatus according to claim 1, wherein the supplement portion supplements electric power information finally measured in a plurality of pieces of electric power information stored into the nonvolatile storage, to the volatile storage.

4. The power supply controlling apparatus according to claim 1, wherein the supplement portion supplements electric power information indicating that the electric power supplied to the another apparatus is “

0”

, to the volatile storage.

5. The power supply controlling apparatus according to claim 1, wherein the supplement portion supplements electric power information calculated from a plurality of pieces of electric power information stored into the nonvolatile storage, to the volatile storage.

6. The power supply controlling apparatus according to claim 5, wherein the supplement portion supplements the electric power information acquired by averaging the plurality of pieces of electric power information stored into the nonvolatile storage, to the volatile storage.

7. The power supply controlling apparatus according to claim 1, wherein a measurement interval of the electric power information by the measurement portion is the same as a supplement interval of the electric power information and the time by the supplement portion.

8. The power supply controlling apparatus according to claim 1, further comprising a restoring portion that restores the electric power information and the measurement time stored into the nonvolatile storage to the volatile storage when the first power supply is turned off and turned on again.

9. A non-transitory computer readable recording medium causing a power supply controlling apparatus to execute a process, the power supply controlling apparatus including a first power supply that supplies electric power to another apparatus, and a second power supply that supplies electric power to the another apparatus even when the first power supply is turned off, the process comprising:

measuring electric power information concerning electric power supplied to the another apparatus;

storing the measured electric power information and measurement time when the electric power information is measured, into a volatile storage, and storing the electric power information and the measurement time stored into the volatile storage, into a nonvolatile storage in desired timing; and

supplementing, when the first power supply is turned off and turned on again, to the volatile storage electric power information and time concerning electric power assumed to be supplied to the another apparatus between final measurement time in a plurality of pieces of measurement time stored in the nonvolatile storage and time when the first power supply is turned on again.
