METHOD AND SYSTEM FOR CHARGING A PLUG-IN ELECTRIC VEHICLE
First Claim
1. A method of charging a battery in a plug-in electric vehicle, comprising the steps of:
- (a) determining if a delayed charging feature is active;
(b) determining if a pre-charge battery parameter satisfies a priority charging threshold; and
(c) when the delayed charging feature is active and the pre-charge battery parameter satisfies the priority charging threshold, then using a control module to enable a priority charging feature that temporarily overrides the delayed charging feature and charges the battery according to a priority charging process.

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.

12. A method of charging a battery in a plug-in electric vehicle, comprising the steps of:
-
(a) determining if the battery is connected to an external power source; (b) determining if the battery is severely depleted; (c) when the battery is connected to the external power source and the battery is severely depleted, then using a control module to bypass a delayed charging process and to charge the battery according to a priority charging process; and (d) when the battery is still connected to the external power source and the battery is no longer severely depleted, then using the control module to stop the priority charging process and to begin the delayed charging process. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A system for charging a battery in a plug-in electric vehicle, comprising:
-
one or more battery sensor(s) coupled to the battery, the battery sensor(s) provide battery parameters; a control module coupled to the battery sensor(s) for receiving the battery parameters, the control module is configured to; determine if a delayed charging feature is active; determine if the battery parameters satisfy a priority charging threshold; and provide command signals when the delayed charging feature is active and the battery parameters satisfy the priority charging threshold; and a battery charger coupled to the control module for receiving the command signals, wherein the command signals cause the battery charger to charge the battery according to a priority charging process.
