Abstract: A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG 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. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

Abstract: A system for charging a battery is provided, in which the system includes a plurality of sensors coupled with the battery, at least one battery charger coupled with the battery, and a processing unit coupled with the sensors and the battery charger. The processing unit includes a battery degradation modeling module and an aging-aware battery charging strategy module. The processing unit receives sensor information from the sensors, uses the battery degradation modeling module to detect aging phenomena or mechanisms that cause aging effect of the battery with a degradation model of the battery based on the sensor information, uses the aging-aware battery charging strategy module to calculate a charging profile for the battery based on the aging effect of the battery and the sensor information, and controls the battery charger to charge the battery based on the charging profile.

Abstract: A series or range extender hybrid vehicle drive system is disclosed having a combustion engine with an exhaust aftertreatment device, a motor/generator, an electrical energy storage and a traction motor. The traction motor is driven using power from the energy storage and/or the engine. A controller of the system is operable to receive input data representative of a requested power from the drive system, a state of charge indication of the electrical energy storage and at least one of the oxygen level in exhaust gas from the engine and temperature in the exhaust gas. The controller is also operable to provide output signals to control torque and speed of the engine and motor/generator to minimize exhaust emissions output and any tracking error of the state of charge of the energy storage to a desired target.
