First Claim
Patent Images
1. A method of charging a hybrid vehicle, comprising:
- receiving electrical power from a utility network at a receptacle coupled to a hybrid vehicle;
measuring an amount of said electrical power transmitted to said receptacle with a meter;
using a controller external to the vehicle to control said flow of electrical power to said vehicle with said meter, the flow being about 1.5 kW or more;
storing said electrical power received by said receptacle in a battery;
transmitting a first signal to a network controller indicating said amount of electrical power measured by said meter; and
receiving a second signal from said network controller at said meter indicating a charging parameter.

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.

10. A method of charging a hybrid vehicle, comprising:
-
receiving electrical power from a utility network at a vehicle, said vehicle having a battery; measuring an amount of said electrical power transmitted to said vehicle with a meter; using a controller external to the vehicle to control said flow of electrical power at about 1.5 kW or more to said vehicle; storing said received electrical power in said battery; transmitting a first signal to a network controller operably coupled to said utility network, said first signal indicating said amount of electrical power measured by said meter, a utility account to which fees are charged for said electrical power received from said utility network, and an amount of charge remaining in said battery; determining with said network controller a vehicle electrical demand from said amount of charge remaining in said battery; and receiving a second signal from said network controller at said meter indicating a charging time period. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
