POST-DETERIORATION PERFORMANCE ESTIMATING APPARATUS AND POST-DETERIORATION PERFORMANCE ESTIMATING METHOD FOR ENERGY STORAGE DEVICE, AND ENERGY STORAGE SYSTEM
First 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 configured to electronically estimate the post-deterioration performance value at a deterioration point usinga relation between a cumulative operating period and a resistance value,a relation between the resistance value and energy storage capacity,andthe cumulative operating period at the deterioration point,wherein the resistance value is a value of direct current resistance or alternating current resistance of the energy storage device, andwherein the energy storage capacity indicates discharge capacity of the energy storage device that is discharged at a first current.

Abstract
A post-deterioration performance estimating apparatus wherein a post-deterioration performance value indicates performance of an energy storage device. The apparatus includes a post-deterioration performance estimator is configured to electronically estimate the post-deterioration performance value at a deterioration point using (1) a relation between a cumulative operating period and a resistance value, (2) a relation between the resistance value and energy storage capacity, and (3) the cumulative operating period at the deterioration point. Alternatively, the post-deterioration performance estimator is configured to electronically estimate the post-deterioration performance value at a deterioration point using (1) a relation between an equilibrial capacity decreased amount, (2) a kinetic capacity decreased amount, and (3) a cumulative operating period at the deterioration point.
