Zusammenfassung:A computer implemented method for controlling energy or power utilization of a battery pack in a rechargeable energy storage system is described. The battery pack is configured to be operated within an operating window defined by its state-of-charge, SOC, according to normal predetermined SOC limits, and extended predetermined SOC limits. The method includes determining a battery pack condition level; comparing the battery pack condition level with a first threshold; providing predicted energy or power utilization of the battery pack; comparing the predicted energy or power utilization with a second threshold. In response of determining that the predicted energy or power utilization is above the second threshold, and that the battery pack condition level is below the first threshold, operating the battery pack within the operating window defined by the extended predetermined SOC limits.
