Abstract
Provided is a method and a battery management system for smoothing the power limit when charging or discharging a battery. The method according to an embodiment of the present disclosure includes determining a first weighting factor based on a maximum charge voltage and a terminal voltage of the battery, determining a second weighting factor based on a previous smoothed charge power limit, a current charge power limit and a current instantaneous power, setting a smaller one of the first weighting factor and the second weighting factor as a first reference weighting factor, and smoothing the current charge power limit based on the previous smoothed charge power limit and the first reference weighting factor.
