CAPACITY ESTIMATING APPARATUS FOR SECONDARY BATTERY |
摘要 |
A capacity estimating apparatus for a secondary battery includes a current-detecting section configured to detect a value of current flowing in the secondary battery; a voltage-detecting section configured to detect a voltage value of the secondary battery; a first estimating section configured to calculate a first estimate value of a remaining capacity of the secondary battery on the basis of an accumulated value of the current values detected by the current-detecting section; and a second estimating section configured to calculate a second estimate value of the remaining capacity of the secondary battery on the basis of the voltage value detected by the voltage-detecting section. The first estimating section is configured to calculate a difference between the first estimate value and the second estimate value, and to correct the first estimate value by correcting the accumulated value so as to gradually reduce the difference. |
