摘要： The present invention relates to a computer implemented method for controlling energy or power utilization of a battery pack (114) in a rechargeable energy storage system, RESS (112), of a vehicle (1). The battery pack (114) 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 comprises: determining a battery pack condition level; comparing the battery pack condition level with a first threshold value; providing predicted energy or power utilization of the battery pack (114); comparing the predicted energy or power utilization with a second threshold value. In response of determining that the predicted energy or power utilization is above the second threshold value, and that the battery pack condition level is below the first threshold value, the method comprises the step of operating the battery pack (114) within the operating window defined by the extended predetermined SOC limits.
