It is aimed to provide an energy management system for an BEV vehiclescomprising an electric powertrain powered by an electric battery, said energy management system comprising a state of charge (SOC) setpoint controller, said SOC setpoint controller arranged to control, when charging the battery, a maximum charge level of the battery in dependence of an orthometric altitude, in order to free up battery capacity to compensate for potential energy to be stored in the battery due to regenerative braking, wherein the SOC setpoint is controlled in dependence of a lookup map that couples the actual vehicle orthometric altitude to a SOC setpoint, wherein the lookup map is provided with a lookup function that determines the maximum charge level at 100 % when the vehicle is in range below a first altitude level; wherein the lookup function lowers the SOC setpoint dependent on the altitude of the vehicle when the vehicle is above the first altitude level; and wherein the lookup function keeps the SOC setpoint at a constant value, when the vehicle is above a second altitude level the SOC setpoint, the second altitude determined by a maximum altitude descent that is available for the BEV vehicle.
