Abstract
Disclosed is a method and a battery management system for periodically determining at least one of charge power limit and discharge power limit of a battery. The method according to an embodiment of the present disclosure includes predicting the terminal voltage and the net resistance of the battery after a predefined time from the current time using an equivalent circuit model for the battery, and determining the charge power limit or the discharge power limit of the battery from the predicted terminal voltage and net resistance.
