Abstract
Provided is an estimation device for estimating an actual capacity of an energy storage device or a total reduction amount of the actual capacity. The estimation device includes a processor which is configured to calculate the actual capacity of the energy storage device or the total reduction amount of the actual capacity based on approximation data where a capacity change curve indicative of a transition of the actual capacity or a transition of the total reduction amount of the actual capacity with respect to an elapsed time is approximated by a plurality of straight lines.
