Document Type and Number:
WIPO Patent Application WO/2023/106166
Kind Code:
A1
Abstract:
In the present invention, information pertaining to factors that affect battery longevity characteristics is presented. This analysis device comprises: an acquisition unit configured to acquire longevity data from cycle measurement data of a target battery; a calculation unit configured to calculate factor strength trend data, which indicates the change in strength of each factor that affects current capacity, and factor data, which represents the relationship of voltage and current capacity of each factor, by factorizing the relationship between the voltage and current capacity of the target battery calculated from the cycle measurement data; and an output unit configured to output the longevity data, the factor data, and the factor strength trend data.
