Beschreibung
Zusammenfassung:	A vehicle including an energy storage device and a powertrain system configured to effect regenerative braking is described. A method for controlling the vehicle includes determining an expected increase in a state of charge of the energy storage device achieved through opportunity charging by employing regenerative braking during an anticipated next trip of the vehicle. A preferred setpoint for the state of charge of the energy storage device is determined based upon the expected increase in the state of charge achieved through opportunity charging, and charging of the energy storage device is controlled during a remote charging event based upon the preferred setpoint for the state of charge of the energy storage device.
