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 them, 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.
