Computer implemented method for controlling energy storage of a battery pack

A computer-implemented method, comprising:

• determining, by a processor device of a computer system, the temperature of the service brakes of an electric vehicle,
• determining, by the processor device, 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;
• comparing, by the processor device, the determined temperature of the service brakes with a predetermined temperature threshold,
• in response of the determined temperature of the service brakes being above the predetermined temperature threshold, operating, by the processor device, the battery pack of the electric vehicle within the operating window defined by extended predetermined voltage limits.

An energy storage system of a vehicle, the energy storage system comprising a battery pack connectable to regenerative braking system configured to charge the battery pack by regenerative braking of the vehicle, and a control unit connectable to service brakes of the vehicle, the control unit being configured to:

• determine the temperature of the service brakes of an electric vehicle,
• determine operating windows of the battery pack 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 voltage predetermined limits;
• compare the determined temperature of the service brakes with a predetermined temperature threshold,
• 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 predefined operating window defined by extended predetermined voltage limits.
