Title:
ELECTRICITY STORAGE DEVICE MANAGEMENT DEVICE AND MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/276910
Kind Code:
A1
Abstract:
A BMU 31 of an electricity storage device 1 executes: third processing (S303) for measuring a temperature during discharge; fourth processing (S304) for estimating an internal resistance value of the electricity storage device 1; fifth processing (S307) for obtaining a temperature correction coefficient corresponding to the measured temperature, on the basis of the internal resistance value estimated by the fourth processing and the internal resistance value at a reference temperature; and sixth processing (S309) for updating the temperature correction coefficient stored in a storage unit 37B in association with the measured temperature, using the temperature correction coefficient obtained by the fifth processing.
