Abstract

A method and system is provided in which multiple Slave Charge Stations are connected to a Master Charge Station which contains the single point metering method or power utility “smart meter” required by power utilities to access the power grid. This method describes the use of a plurality of Slave Charge Stations attached to the Master Charge Station using a daisy chain or hub and spoke attachment means.

Claims

1. ) A system comprising:

a. A Master Charge Station including;

a smart utility meter, control module with a Micro-Processor, WireLine Radio, Electric Vehicle Charge Switch, Electric Vehicle power connection, Slave power distribution connections. PowerLine Network Connection, Utility power Connection.

b. A Slave Charge Station including;

a Slave control module with the unique ID, PowerLine Network Connection to a Master Charge Station, Electric Vehicle Charge Switch, WireLine radio, Wireline or Wireless Radio, Electric Vehicle power cable.

c. PowerLine Network

2. ) System of claim 1 wherein utility power is connected to the Master Charge Station by the Utility Power Connection.

3. ) System of claim 1 wherein each communication packet from an Electric Vehicle connected to a Slave Charge Station is received by a WireLine Radio on a point to point Electric Vehicle Power Connection.

4. ) System of claim 1 wherein the received communication packet is appended with the Slave Charge Station unique ID number.

5. ) System of claim 1 wherein the appended communication packet by the Slave Charge Station is transmitted by a Wireless or WireLine radio that is attached to the PowerLine Network or over the air to the Master Charge Station

6. ) System of claim 1 wherein the Slave Charge Station generates a Status packet by using its unique ID in the address field and appending the packet by its unique ID and transmitted by a WireLine radio that is attached to the PowerLine Network or a wireless Radio to the Master Charge Station.

7. ) System of claim 1 wherein the Master Charge Station receives a communication packed from a Slave Charge Station by a WireLine Radio attached to the PowerLine Network or a wireless radio.

8. ) System of claim 1 wherein the Master Charge Station Pairs the Slave Charge Station unique ID with the attached Electric Vehicle'"'"'s Unique ID by means of appending the Slave Charge Station Unique ID to the communication packet.

9. ) System of claim 1 wherein the Master Charge Station receives status from the Slave Charge Station by comparing the Communication Packet Address with the appended Unique ID number.

10. ) System of claim 8 Wherein the Master Charge Station directs transactions to a Slave Charge Station attached Electric Vehicle by appending the paired Slave Charge Station'"'"'s unique ID to the communication packet.

11. ) System of claim 9 Wherein the Master Charge Station directs commands to a Slave Charge Station by appending the Slave Charge Station'"'"'s unique ID to the communication packet.

12. ) A Secure Distributed Point of Sale system comprising in combination:

a. A Master Charge Station comprised of;

a smart utility meter, control module with a Micro-Processor, WireLine Radio, Electric Vehicle Charge Switch, Electric Vehicle power connection, Slave power distribution connections. PowerLine Network Connection, Utility power Connection.

b. A plurality Slave Charge Stations comprised of;

a Slave control module with the unique ID, PowerLine Network Connection to a Master Charge Station, Electric Vehicle Charge Switch, One WireLine Radio, One Wireline or Wireless Radio second electric vehicle power cable.

c. PowerLine Network

d. A plurality of Electric Vehicles comprised of;

an Electric Vehicle Authentication Control Module, a Wireline Radio, a Wireless Radio.

13. ) The system of claim 12 wherein an encrypted communication session between the Electric Vehicle Authentication Control Module and the Master Charge Station control module by means of a Slave Charge Station that is connected to the Electric Vehicle.

14. ) The system of claim 13 wherein the unique address of the Slave Charge Station that is connected to the Electric Vehicle requesting a charge is inserted in communication between the Electric Vehicle and the Master Charge Station.

15. ) The system of claim 14 wherein control messages are sent from the Master Charge Station to the Slave charge Station which is connected to the Electric Vehicle requesting a charge using the inserted unique address.

16. ) The system of claim 14 wherein the Master Charge Station appends all communication responses by the unique address received from the Slave Charge Station which is connected to the Electrical Vehicle requesting a charge which is repeated to the Electric Vehicle by the Slave Charge Station repeater.

17. ) The system of claim 14 wherein status to a command sent from the Master Charge Station to the Slave Charge Station that is connected to the Electric Vehicle is sent from the Slave Charge Station that is connected to the Electric Vehicle to the Master Charge Station by using the unique address of the Slave Charge Station that is connected to the Electric Vehicle.
