Title:
BATTERY DIAGNOSTIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/127319
Kind Code:
A1
Abstract:
A battery diagnostic system (100) for estimating the SOH which indicates the degree of deterioration of a secondary battery (110) comprises a model unit (172), an SOH calculation unit (173), and an SOH estimation unit (174). The model unit acquires usage history data which indicates the usage state of the secondary battery, and calculates the SOH on the basis of the usage history data. The SOH calculation unit acquires, as sensing data, a physical quantity which changes according to the degree of deterioration of the secondary battery, and calculates the SOH on the basis of the sensing data. On the basis of the SOH which has been calculated by the model unit and the SOH which has been calculated by the SOH calculation unit, the SOH estimation unit estimates an optimized SOH by synthesizing both of the calculation results.
