SUB-NETWORK LOAD MANAGEMENT FOR USE IN RECHARGING VEHICLES EQUIPPED WITH ELECTRICALLY POWERED PROPULSION SYSTEMS
First Claim
1. A system for controllably providing power to recharge a plurality of vehicles, each of which includes a propulsion system powered, at least in part, by electric power, at least some of which is stored onboard the vehicle in an electric power storage apparatus, comprising:
- an Electric Grid Interconnect which is connected to a source of electric power for providing electric power to an electric power storage apparatus which is located in each vehicle;
a plurality of electric outlets, each of which is connected to said Electric Grid Interconnect via a conductive path and to one of said plurality of vehicles, to enable a flow of electric power from said source of electric power to said electric power storage apparatus located in said one vehicle;
an electric outlet identification, which uniquely identifies said electric outlet to said vehicle when said vehicle is connected to said electric outlet; and
wherein said Electric Grid Interconnect comprises;
a load manager, responsive to receipt of said electric outlet identification and electric power load data from said vehicles, for enabling a subset of said plurality of vehicles to receive a flow of electric power from said source of electric power.

Abstract
The E-Grid Sub-Network Load Manager operates to regulate the demands presented by the vehicles to the associated Sub-Network thereby to spread the load presented to the service disconnect over time to enable the controllable charging of a large number of vehicles. The load management can be implemented by a number of methodologies, including: queuing requests and serving each request in sequence until satisfaction; queuing requests and cycling through the requests, partially serving each request, then proceeding to the next until the cyclic partial charging service has satisfied all requests; ordering requests pursuant to a percentage of recharge required measurement; ordering requests on an estimated connection time metric; ordering requests on a predetermined level of service basis; and the like. It is evident that a number of these methods can be concurrently employed thereby to serve all of the vehicles in the most efficient manner that can be determined.
