Abstract
The remaining capacity of a battery obtained by integrating current and that obtained from the estimated open circuit voltage of the battery are weighted with a weight which varies depending on the operating conditions of the battery as needed and the weighted remaining capacities are combined into the final remaining capacity. Thus, the disadvantages of the remaining capacity based on current integration and those of the remaining capacity based on the estimated open circuit voltage cancel each other out and the advantages of the respective remaining capacities can be fully utilized. The uniform calculation accuracy can be ensured and the final remaining capacity can always be obtained with accuracy.
