MANAGING DEVICE AND MANAGING METHOD FOR POWER-STORING DEVICE OF MOVING BODY

WIPO Patent Application WO/2019/155781

A1

This management device comprises: a degradation-state-estimation means that estimates the state of degradation of a power storage device installed in a moving body and outputs power-storage-device-degradation-state information that includes the degradation-estimation date and time when the degradation state of the power storage device was estimated as well as the degradation-state-estimation value for the power storage device on the degradation-estimation date and time; a reference-degradation-pattern-calculation means that performs management by calculating a reference degradation pattern in association with one or more assembly operations allocated to the moving body, the reference degradation pattern being calculated for each of the operations; and a degradation-state-assessment means that assesses the state of degradation of the power storage device on the basis of the output of the reference-degradation-pattern-calculation means. The reference degradation pattern indicates the change over time in the degree to which the state of degradation of the power storage device has decreased when the device is driven according to one operation allocated to the moving body, the reference degradation pattern being set on the basis of at least one degradation-rate-setting value and the time required for one operation.
