VEHICLE PLUG-IN ADVISORY SYSTEM AND METHOD
First Claim
1. A control system for a vehicle comprising:
- a controller configured to receive input signals indicative of transmission mode, charger connectivity status and ambient temperature, and output a plug-in advisory signal based upon the input signals; and
a user interface in communication with the controller and configured to output a plug-in advisory message in response to the plug-in advisory signal.

Abstract
Many plug-in electric vehicles include a high voltage battery for outputting electrical power to a traction motor in order to propel the vehicle. Storing a plug-in electric vehicle in cold or hot ambient temperatures can cause the high voltage battery to become performance limited. If the vehicle has a battery thermal system, then plugging in the vehicle to an external power supply when not in use can help keep the battery at a temperature where performance will not be limited. To educate a driver and increase the probability of avoiding performance limits, a user interface may convey a reminder message advising or alerting the driver to plug the vehicle in to an external power supply at the end of a drive when the ambient temperature is extreme.
