1. A plug-in series hybrid electric vehicle, comprising:
a powertrain including an engine and a motor/generator (MG);
an energy storage device coupled to the MG; and
a controller coupled to the powertrain to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold power value, wherein the controller maintains an aftertreatment temperature associated with the engine above a threshold temperature during one or more of: a blended mode, a battery recharging mode, or a charge sustaining mode of the vehicle.
