A system and method for charging a battery in a plug-in electric vehicle. In an exemplary embodiment, the present method uses a charging profile and a scheduled departure time to develop a charging scheme for a plug-in electric vehicle that balances battery life with electricity costs. The charging scheme attempts to reduce the amount of time at which the battery is maintained at elevated state-of-charge (SOC) levels before a scheduled departure time, while still satisfying the electricity rate preferences established by the user. Reduced time spent at elevated SOC levels can, over the long term, improve battery life by increasing the capacity and performance of the battery.

Method for charging a plug-in electric vehicle

Methods and systems are provided for determining a desired yaw rate for a vehicle. The vehicle has a plurality of handling states and comprises a yaw rate sensor for determining an actual yaw rate. The method comprises selecting one of the plurality of handling states, determining the desired yaw rate for the vehicle based on the road wheel angle, the velocity, and the selected one of the plurality of handling states, and activating one or more vehicle stability control measures if the difference between the desired yaw rate and the actual yaw rate for the vehicle exceeds a predetermined threshold.
