Abstract

See full text

Intelligent battery depletion techniques for a range-extended electrified vehicle (REEV) include receiving at least (i) a state of charge (SOC) of a battery system of the REEV and (ii) a distance for a trip of the REEV, controlling an electrified powertrain (engine and electric motor) of the REEV to generate a drive torque to satisfy a driver torque request, based on at least the battery system SOC and the trip distance, determining, an optimized charge depletion or allocation profile for the trip for powering the electric motor/battery system, and controlling the electrified powertrain based on the blended charge depletion or allocation profile until the trip distance has been reached or the battery system SOC reaches a desired minimum level, and then transitioning to a charge sustaining mode where the engine generates the drive torque and maintains the battery system SOC at the desired minimum level.
