Computer implemented method for controlling energy storage of a battery pack

A computer system includes a processor device configured to determine the temperature of the service brakes of an electric vehicle, determine operating windows of a battery pack of the electric vehicle defined by its operating voltage according to default predetermined voltage limits, and according to extended predetermined voltage limits in which the upper limit exceeds the corresponding upper limit of the default predetermined voltage limits; compare the determined temperature of the service brakes with a predetermined temperature threshold, and in response of the determined temperature of the service brakes being above the predetermined temperature threshold, operate the battery pack of the electric vehicle within the operating window defined by extended predetermined voltage limits.
