Summary: | A distributed battery management system, for managing a plurality of battery management units, wherein each of the battery management units, includes: a first battery cell, forming a charge-discharge connection at least with a second battery cell in a second battery management unit; a monitor circuit, monitoring a discharge process of the first battery cell via the charge-discharge connection, to record a discharge voltage time history of the first battery cell; and a calculation unit, calculating a real-time maximal energy storage capacity of the first battery cell, by an electrochemical equation calculated based on the discharge voltage time history and an electrical current time history of the first battery cell during the discharge process. The history of the real-time maximal energy storage capacity of the battery cell may be stored as an identity resume of the battery cell, in a battery resume record device. |
