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: Presented are charging systems for provisioning vehicle grid integration (VGI) demand-response (DR) activities, methods for making/using such systems, and vehicles with bidirectional charging and VGI DR capabilities. A method of controlling VGI operations for a host vehicle includes a resident/remote vehicle controller receiving user-specific data input by the host vehicle's operator and crowd-sourced data output by third-party vehicles deemed comparable to and located within a predefined region of the host vehicle. A predicted battery life of the battery pack resulting from the host vehicle performing VGI operations is estimated using a non-iterative, non-recursive closed-form battery life model based on the user-specific and crowd-sourced data. The controller uses the predicted battery life to determine a value proposition indicating a predicted value and battery capacity for performing VGI operations, and commands a resident subsystem of the host vehicle to execute a control operation for the VGI operation based on the value proposition.

Abstract: Preemptively charging rechargeable energy storage systems (RESSs) in advance of an electrical grid outage. The preemptive charging may include generating a weather map of a geographical area anticipated to be impacted with a storm or a natural event of a severity predicted to induce a power outage, which may include generating a distribution map of an electrical power distribution network within the geographical area, generating an outage map by overlaying the weather map relative to the distribution map to identify one or more intersections where the power outage is predicted, and scheduling or otherwise implementing preemptively charging of one or more the RESSs downstream of the intersections in advance of the power outage.
