Method and apparatus for recharging an energy storage device on a vehicle
First Claim
1. A method for controlling a vehicle including an energy storage device and a powertrain system including regenerative braking capability, the method comprising:
- determining an anticipated next trip of the vehicle;
determining an expected increase in the state of charge achieved through opportunity charging of the energy storage device employing regenerative braking during the anticipated next trip of the vehicle;
determining a desired setpoint for the state of charge of the energy storage device prior to the anticipated next trip of the vehicle based upon the expected increase in the state of charge achieved through the opportunity charging of the energy storage device during the anticipated next trip of the vehicle; and
controlling charging of the energy storage device during a remote charging event prior to the anticipated next trip of the vehicle based upon the desired setpoint for the state of charge of the energy storage device.

Abstract
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.
