A method including a remaining charge capacity determination step to determine a first remaining charge capacity from the first open circuit voltage and a second remaining charge capacity from the second open circuit voltage, a change in remaining charge capacity computation step to compute the change in remaining charge capacity from the difference between the first remaining charge capacity and the second remaining charge capacity, and a full-charge capacity computation step to compute the battery full-charge capacity from the change in remaining charge capacity and the change in charge capacity. The method computes battery full-charge capacity from the change in charge capacity and the change in remaining charge capacity when at least one of the values, namely the change in charge capacity, the change in remaining charge capacity, and the difference between the first open circuit voltage and the second open circuit voltage, is greater than a preset value. |
