Abstract

A method determines and/or predicts a maximum power capacity of a battery by using a model of the battery based on an electric equivalent circuit diagram that predicts the maximum power capacity of the battery. The maximum power of the battery is prognosticated for a defined prognosis period and for the different operating modes with respect to the charging or discharging operation, considering the maximum allowable operating voltage and the maximum allowable operating current.
