Title:
REMAINING CAPABILITY EVALUATION METHOD FOR SECONDARY BATTERY, REMAINING CAPABILITY EVALUATION PROGRAM FOR SECONDARY BATTERY, COMPUTATION DEVICE, AND REMAINING CAPABILITY EVALUATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/171688
Kind Code:
A1
Abstract:
A degradation diagnosis unit 21a of a computation device 20 composing this remaining capability evaluation system 3 uses measured values to diagnose the degree of degradation of a secondary battery 5 that has been used in a primary way. A degradation speed update unit 21b updates a degradation speed for the secondary battery 5 on the basis of the diagnosis of the secondary battery 5. On the basis of the updated degradation speed and how the secondary battery 5 will be used in a secondary way, a remaining capability estimation unit 21c estimates what the remaining capability of the secondary battery 5 will be after the same starts being used in the secondary way.
