TECHNIQUES FOR MANAGING POWER DISTRIBUTION BETWEEN ELECTRIFIED VEHICLE LOADS AND HIGH VOLTAGE BATTERY SYSTEM DURING LOW STATE OF CHARGE CONDITIONS

Electrified vehicle energy management techniques include determining when a state of charge (SOC) of a high voltage (HV) battery system is below an SOC threshold and, in response, determining whether an electric motor is operating as a generator or a consumer, when the electric motor is operating as a consumer, calculating a power offset value based on a difference between an available power of the HV battery system and a set of HV loads, when the electric motor is operating as a generator and its generated power is less than the set of HV loads, calculating the power offset value based on a difference between the generated power and the set of HV loads, and controlling the set of HV loads using a final output power calculated based on the power offset value and a minimum power for the set of HV loads.
