A method for managing power in a charging station for charging electric vehicles, the charging station including several charging points, the method is used to predict accurately a consumption of the charging station, with satisfaction of clients. The method includes determining a statistic model of occupation of the charging station, determining some scenarios of occupation of the charging station, take into account the statistic model, determining, for each power profile among many power profiles, some scenarios which are valid and some other scenarios which are non-valid, taking in account client satisfaction rate, selecting an optimum power profile among said many power profiles for which a number of non-valid scenarios does not exceed a predefined threshold.
