Abstract: An assessment for loss of isolation in a rechargeable energy storage systems (RESS). The assessment may include collecting isolation resistance data for a plurality of RESSs operating onboard a fleet of vehicles, applying statistical methods and engineering rules to remove erroneous peaks and duplicate values from the isolation resistance data, generating one or more isolation rules based on the isolation resistance data to represent thresholds for determining whether a loss of isolation has occurred for the RESS associated therewith, and identifying an isolation issue type for the RESSs determined to have the loss of isolation.

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.
