Title:
BATTERY AUTHENTICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/090215
Kind Code:
A1
Abstract:
The present invention comprises: a data acquisition unit (103a) that acquires, as time series data, battery data which includes a signal value indicating the state of a secondary battery (101) and a physical value indicating a physical quantity of the secondary battery; a data standardization unit (201b) that performs standardization of the signal value and the physical value; a code generation unit (201c) that generates a classification code for classifying the secondary battery on the basis of the standardized signal value; a deterioration state calculation unit (201d) that calculates the deterioration state of the secondary battery on the basis of the standardized physical value; a deterioration state integration unit (201e) that integrates the classification code and the deterioration calculation result of the secondary battery so as to generate a calculation result-equipped classification code; and a deterioration state provision unit (201g) that, when there has been a request for the deterioration calculation result using the classification code, compares the classification code and the calculation result-equipped classification code and provides the deterioration calculation result.
