An intelligent battery charge depletion system for an electrified powertrain of a range-extended electrified vehicle (REEV) determines a modified state of charge (SOC) setpoint based on an estimated road load and an estimated gross combined vehicle weight (GCCW) of the REEV. The modified SOC setpoint is different than a charge sustaining SOC setpoint and is for a battery system having an SOC and that is configured to power an electric motor of the electrified powertrain. The estimated road load is for a road segment that the REEV is traversing. The system also controls the electric motor based on the modified SOC setpoint and the battery system SOC to maintain a torque reserve that the electric motor and the battery system can use when needed; and controls an engine of the electrified powertrain to selectively recharge the battery system.
