Abstract: An off-board charging device disposed to electrically charge an electric energy storage system via an electrical charging system on-board a vehicle is described. This includes an electric machine electrically connected to the electric energy storage system and is disposed to supply propulsion effort to the vehicle. A method for controlling the off-board charging device includes determining severity of a drive cycle that occurs prior to a charging event for the electric energy storage system. A charging profile is determined based upon the severity of the drive cycle. A controller commands operation of the off-board charging device based upon the charging profile.

Abstract: A method and system for manipulating, adjusting or otherwise controlling a state-of-charge (SOC) operating range for a high voltage vehicle battery, such as the type used for hybrid or electric vehicle propulsion. By providing a dynamic SOC operating range that changes in response to changing battery conditions, the battery performance may be improved so that the battery life is extended. Depending on the particular embodiment, the dynamic SOC operating range may have different combinations of hard and/or soft boundaries or limits.
