1. A method for charging a plurality of hybrid vehicles connected to a utility network, said method comprising:
- determining a number of hybrid vehicles connected to said utility network, said hybrid vehicles being positioned in separate locations;
determining an electrical power characteristic of said utility network to deliver electrical power to at least one location;
determining an off-peak period based on an electrical demand profile for said utility network;
scheduling charge times for each of said hybrid vehicles during said off-peak period, wherein said scheduling is based on said electrical power characteristic, said electrical demand profile and said number of said hybrid vehicles; and
,activating charging of each of said hybrid vehicles during said scheduled charge times.

Abstract
A system and method for recharging a plug-in hybrid vehicle. The system includes a controller that schedules the recharging of the vehicles on local electrical distribution networks. The system arranges the schedule to minimize the demand loading on the local distribution network to more efficiently operate power plants providing electrical power to the distribution networks. A system for collecting charges associated with the recharging of plug-in hybrid vehicles is also disclosed providing for prepaid utility accounts.
