1. A device comprising:
- an interface configured to receive information for a parameter indicative of a status of a battery; and
a processor, coupled to said interface, configured to calculate a remaining capacity of said battery and calculate a capacity ratio of the calculated remaining capacity to a capacity reference of said battery, configured to compare said parameter with a parameter reference to generate a first comparison result, configured to compare said capacity ratio with a ratio reference to generate a second comparison result, configured to set an amount according to said first and second comparison results, and configured to change said calculated remaining capacity by said amount.

Abstract
A device includes an interface and a processor. The interface receives information for a parameter indicative of a status of a battery. The processor calculates a remaining capacity of the battery, calculates a capacity ratio of the calculated remaining capacity to a capacity reference of the battery, compares the parameter with a parameter reference to generate a first comparison result, compares the capacity ratio with a ratio reference to generate a second comparison result, sets an amount according to the first and second comparison results, and changes the calculated remaining capacity by the amount.

10. A method for estimating a remaining capacity of a battery, said method comprising:
-
calculating, using a processor, a capacity ratio of a calculated remaining capacity of said battery to a capacity reference of said battery; comparing a parameter indicative of a status of said battery with a parameter reference to generate a first comparison result; comparing said capacity ratio with a ratio reference to generate a second comparison result; setting an amount according to said first and second comparison results; and changing said calculated remaining capacity by said amount. - View Dependent Claims (11, 12, 13)
