Claim:
1. A post-deterioration performance estimating apparatus wherein a post-deterioration performance value indicates performance of an energy storage device, the apparatus comprising: a post-deterioration performance estimator apparatus configured to electronically apply a first relational expression to electronically estimate the post-deterioration performance value at a deterioration point, the first relational expression includes a first capacity decreased amount and a second capacity decreased amount, wherein equilibrial capacity indicates discharge capacity of the energy storage device that is discharged at a second current of a current value smaller than a first current, wherein the post-deterioration performance estimator apparatus is configured to electronically obtain the first capacity decreased amount by electronically subtracting the equilibrial capacity at the deterioration point from an initial capacity of the energy storage device, wherein energy storage capacity indicates discharge capacity of the energy storage device that is discharged at the first current, wherein the post-deterioration performance estimator apparatus is configured to electronically obtain the second capacity decreased amount by electricity subtracting the energy storage capacity at the deterioration point from the equilibrial capacity, and wherein replacement of the energy storage device is carried out at a timing based on the post-deterioration performance value.
