Abstract: A method for adjusting state of charge (SOC) limits aboard a motor vehicle having a propulsion battery pack includes receiving a pre-drive information set via a host computer and identifying, from the pre-drive information set, a probability that the motor vehicle is about to embark on a road trip. The road trip is a drive event in which the motor vehicle will travel outside of a predetermined area. The method further includes expanding the SOC limits of the propulsion battery pack when the motor vehicle is about to embark on the road trip, such that a total SOC window of the propulsion battery pack is increased for a duration of the road trip.
