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.

Abstract: A method for determining an optimal state-of-charge (SOC) operating window for a battery for use in an electric vehicle includes learning a pattern of periodic charging of the battery for a plurality of time periods and a pattern of periodic usage of the battery for the plurality of time periods, determining a periodic energy requirement for the battery for the plurality of time periods based on the learned patterns using a statistical model, and setting a maximum SOC level and a minimum SOC level for the SOC operating window based on two or more of the periodic energy requirement, the learned patterns and a battery chemistry of the battery.

Abstract: Methods and systems are provided for calibrating one or more limits of a battery of a vehicle, the battery having state of charge limits and power limits. A history of environmental conditions for the vehicle is obtained and stored in a memory. One or more of the state of charge limits, one or more of the power limits, or both are adjusted based on the history of environmental conditions and usage severity using a processor.
