Abstract:
A system and method for charging a battery in a plug-in electric vehicle. In an exemplary embodiment, the method determines if a delayed battery charging feature is active and if the battery is severely depleted. If both conditions are satisfied, the method enables a priority charging feature that temporarily overrides the delayed charging feature and begins charging the battery according to a priority charging process until it reaches a level where it is no longer severely depleted. At this point, the method may terminate the priority charging process and initiate the delayed charging process, which is designed to take advantage of off-peak electricity rates, anticipated times of vehicle use, etc.
