Abstract
Official abstract text for this publication.
An apparatus for calculating a residual capacity of a secondary battery is provided. The apparatus calculates the residual capacity of energy in the secondary battery which is charged/discharged. The apparatus includes an arithmetic unit which estimates and calculates a first residual capacity based on a charge/discharge voltage corresponding to a residual capacity of the secondary battery, calculates a second residual capacity based on an integrated value of a charge/discharge current of the secondary battery, weights the charge/discharge voltage of the secondary battery with the first residual capacity or the second residual capacity according to the voltage changing rate, and combines the results of the weighting to obtain the residual capacity of the secondary battery.
