Electrification control systems and methods for electric vehicles
A system is provided for performing an automated electrification operation for an electric vehicle ( 102 ) using a processor ( 122 ). An electrification controller ( 126 ) communicates with a model generation unit ( 128 ). The model generation unit ( 128 ) generates a model representative of a power consumption trend of the electric vehicle ( 102 ). The electrification controller ( 126 ) sets a target power margin for the electric vehicle ( 102 ) based on the model such that the target power margin is close to a minimum state-of-charge (SOC) threshold of an energy storage supply ( 124 ) of the electric vehicle ( 102 ). The target power margin represents a difference between the minimum SOC threshold and an ending power level of the energy storage supply ( 124 ) after completion of a mission associated with the electric vehicle ( 102 ). The processor ( 122 ) performs the automated electrification operation for the electric vehicle ( 102 ) based on the target power margin.
