1. A method of operation in an electric-vehicle charging station, the method comprising:
- determining respective maximum rates of charge to be delivered to a plurality of electric vehicles connected to the charging station, wherein the charging station has a total charging capacity; and
allocating respective portions of the total charging capacity of the charging station to each of the plurality of electric vehicles, the respective portions being non-uniform and determined based, at least in part, on the respective maximum rates of charge to be delivered to the plurality of electric vehicles, wherein at least one of the plurality of electric vehicles is allocated a nonzero charging rate that is less than a requested vehicle charging rate of the at least one of the plurality of electric vehicles in response to a sum of requested vehicle charging rates of the plurality of electric vehicles exceeding the total charging capacity of the charging station.

14. A method of operation in an electric-vehicle charging station, the method comprising:
-
receiving a request to charge a first vehicle at a first charging rate while charging a second vehicle at a second charging rate, wherein a sum of requested charging rates of vehicles charging at the electric-vehicle charging station, including the first charging rate and the second charging rate, exceeds a total charging capacity of the electric-vehicle charging station; and reducing the second charging rate to a third, nonzero, charging rate to enable allocation of a portion of the total charging capacity of the electric-vehicle charging station to the first vehicle without exceeding the total charging capacity of the electric-vehicle charging station. - View Dependent Claims (15, 16, 17, 18, 19, 20)
