<p><P>PROBLEM TO BE SOLVED: To provide an electronic apparatus capable of precisely calculating and managing a remaining capacity of a battery pack while taking into account of temperature characteristics of the battery pack during discharge. <P>SOLUTION: In the electronic apparatus 301, an actual power consumption amount is calculated from an operation time of an operation mode and a power consumption data table, and a discharge temperature load correction coefficient is calculated from an operation temperature value of the electronic apparatus and a discharge temperature load characteristic data table. A correction power consumption amount is calculated from the actual power consumption amount and the discharge temperature load correction coefficient, and a present remaining capacity value is calculated by subtracting the correction power consumption amount from the remaining capacity value of the battery pack 128. The calculated present remaining capacity value is written in a nonvolatile memory 133 to update the remaining capacity value. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
