Title:
BATTERY RESIDUAL VALUE MANAGEMENT SYSTEM AND BATTERY RESIDUAL VALUE MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/139684
Kind Code:
A1
Abstract:
The present disclosure discloses a technique for more accurately evaluating the residual value of secondary batteries. Thus, the present disclosure provides a battery residual value management system that manages the residual value of batteries and comprises: at least one storage device which, in a multidimensional vector space configured by at least three indicators for evaluating the residual value of batteries, stores multidimensional vector space information having a plurality of regions for determining residual value-specific ranks of the batteries and defined by one or more threshold values set for each of the indicators; and at least one processor which acquires the multidimensional vector space information from the storage device and determines the residual value-specific rank of the battery undergoing residual value assessment by determining the specific region to which the battery undergoing residual value assessment belongs, among the plurality of regions in the multidimensional vector space, on the basis of the at least three indicators for the battery undergoing residual value assessment.
