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.

Claims

1. A method for recharging a plurality of hybrid vehicles connected to a local utility network, said method comprising:

determining a number of hybrid vehicles connected to said local electrical distribution network;

determining electrical power characteristics of said local electrical distribution network;

determining an off-peak period based on an electrical demand profile for said local electrical distribution network;

scheduling recharge times for each of said plurality of hybrid vehicles, wherein said scheduling is based on a balancing of said electrical power characteristics, said demand profile and said number of said hybrid vehicles; and

,

activating recharging of each of said hybrid vehicles at predetermined times during said off-peak period.

2. The method for recharging a plurality of hybrid vehicles connected to a local electrical distribution network of claim 1 wherein said electrical power characteristics includes a maximum power delivery threshold of said local electrical distribution network.

3. The method for recharging a plurality of hybrid vehicles of claim 2 further comprising:

determining availability of electric power to said local electrical distribution network; and

,

scheduling said recharge times of said hybrid vehicles to maximize the number of said vehicles being recharged without exceeding said maximum power delivery threshold of said local electrical distribution network.

4. The method for recharging a plurality of hybrid vehicles of claim 3 further comprising:

determining a base electrical demand for said electrical loads on said local electrical distribution network; and

,

determining a hybrid vehicle demand for said plurality of hybrid vehicles on said local electrical distribution network.

5. The method for recharging a plurality of hybrid vehicles of claim 4 further comprising:

deactivating said recharging of one or more hybrid vehicles if a combination of said base electrical demand and said hybrid vehicle demand exceeds said maximum power delivery threshold of said local electrical distribution network.

6. The method for recharging a plurality of hybrid vehicles of claim 4 further comprising:

deactivating said recharging of one or more hybrid vehicles if a combination of said base electrical demand and said hybrid vehicle demand exceeds said maximum available power from a utility distribution network to said local electrical distribution network.

7. A method for recharging a plurality of vehicles comprising:

determining a number of vehicles electrically coupled for recharging batteries associated with said vehicles;

determining a capacity for recharging said vehicles;

determining a first time period for recharging said vehicles, wherein said time period corresponds to a higher capacity time period;

determining a second time period for each of said vehicles, wherein each of said second time periods is during said first time period; and

,

recharging each of said vehicles during said respective second time periods

8. The method of claim 7 wherein said capacity includes a maximum electrical power delivery parameter.

9. The method of claim 8 wherein said maximum electrical power delivery parameter is for a local electrical distribution network.

10. The method of claim 9 further comprising:

determining an amount of electrical power available to be delivered to said local electrical distribution network; and

,

scheduling said second time periods of said vehicles to maximize a number of said vehicles being recharged without exceeding said maximum electrical power delivery parameter.

11. The method of claim 10 further comprising scheduling said second time periods of said vehicles to maximize a number of said vehicles being recharged without exceeding said amount of available electrical power.

12. The method of claim 11 further comprising:

determining a base level of electrical demand for said local electrical distribution network; and

,

determining a demand from said vehicles on said local electrical distribution network,

13. The method of claim 12 further comprising stopping said recharging of one or more vehicles when a combined demand of said base level of electrical demand and said vehicle demand exceeds a threshold.

14. The method of claim 13 wherein said threshold is said maximum electrical power delivery parameter.

15. The method of claim 13 wherein said threshold is said amount of available electrical power.
