| description | A residual capacity calculation apparatus for a battery includes a current detection device to detect a charge/discharge current of the battery and a voltage detection device to detect an open circuit voltage of the battery, and a controller. The controller is configured to calculate a first residual capacity based on an integrated value of the charge/discharge current of the battery, calculate a second residual capacity based on the open circuit voltage of the battery, determine a blend rate of the second residual capacity based on a deviation between the first residual capacity and the second residual capacity, calculate a post-combination residual capacity by subjecting the first residual capacity and the second residual capacity to weighted combination with use of the blend rate, and increase the blend rate as the deviation between the first residual capacity and the second residual capacity increases. |
