A computer-implemented method of brake management in an electric or hybrid electric heavy-duty vehicle that has batteries which are configured to absorb energy from regenerative braking is provided. Topographic data containing information about an upcoming downhill slope is obtained. A state of charge target (SOC target) below 100% for said batteries is determined. Based on the obtained topographic data, a total brake power required for maintaining the speed of the heavy-duty vehicle at or below a selected speed limit of the heavy-duty vehicle throughout the travel in the downhill slope is determined. The determined total brake power is in the form of at least one of regenerative braking, auxiliary braking and service braking of the heavy-duty vehicle. The speed of the heavy-duty vehicle when travelling in said downhill slope is controlled by applying said determined total brake power such that the state of charge of the batteries remains below or equal to said SOC target throughout the travel in the downhill slope.
