METHOD FOR CHARGING A PLUG-IN ELECTRIC VEHICLE
First Claim
1. A method for charging a plug-in electric vehicle with an external power source, comprising the steps of:
- (a) determining an overall available power that is available from the external power source;
(b) determining an overall requested power that is requested by a plurality of vehicle systems; and
(c) determining if the overall requested power exceeds the overall available power, and if the overall requested power does exceed the overall available power then allocating the overall available power from the external power source to the plurality of vehicle systems.

Abstract
A system and method for charging a plug-in electric vehicle with an external power source, even when the overall power requested by the plug-in electric vehicle exceeds the overall power available from the external power source. In an exemplary embodiment, a method determines the overall power requested by one or more vehicle systems, and then compares that to the overall available power from the external power source. If the overall requested power exceeds the overall available power, then the power from the external power source is allocated or apportioned to the different vehicle systems according to an allocation process that may consider factors like predetermined priorities and current vehicle conditions.

-
(a) determining an overall available power that is available from the external power source; (b) determining an overall requested power that is requested by a plurality of vehicle systems, wherein the plurality of vehicle systems includes a high voltage battery unit and a battery thermal system; and (c) determining if the overall requested power exceeds the overall available power, and if the overall requested power does exceed the overall available power then distributing the overall available power to the plurality of vehicle systems, wherein the amount of power that is distributed to each of the plurality of vehicle systems is influenced by a predetermined priority and/or a current vehicle condition. - View Dependent Claims (13, 14, 15, 16, 17)
