Abstract

An apparatus to provide controlled electrical energy in a substantially public setting includes a power control unit. The unit includes credential entering circuitry which, upon authentication, provides access to a supply of AC-type electrical energy which can be used to recharge batteries of a vehicle. Authentication can be carried out locally, or at a displaced access control system. An access credential can be entered via a card reader or a wires receiver.

Claims

1. An outlet control unit comprising:

a housing;

a device to receive an access requesting input, carried by the housing; and

control circuitry, carried by the housing, and responsive to the access requesting input to switch electrical energy to an output port carried by the housing.

2. A unit as in claim 1 which includes a port to communicate with a displaced access control system.

3. A unit as in claim 1 where the device includes at least one of a card reader, or a wireless receiver.

4. A unit as in claim 3 where the card reader responds to at least one of a magnetic input, an optical input or an RF input.

5. A unit as in claim 3 where the control circuitry includes a programmed processor and associated control programs to activate energy switching circuits to coupled electrical energy from a source to the output port.

6. A unit as in claim 3 where the control circuits include current monitoring circuitry.

7. A unit as in claim 2 where the control circuitry transmits the access requesting input to the access control system for authentication.

8. A unit as in claim 7 where the control circuitry responds to a received authentication signal, from the access control system to switch electrical energy to the output port.

9. A unit as in claim 8 where the device includes at least one of a card reader, or a wireless receiver.

10. A unit as in claim 9 where the control circuitry monitors current flow from the output port and terminates that flow in response to at least one selected condition.

11. A unit as in claim 10 where the selected condition is from a class which includes current flow from the output port terminating, or, current flow from the output port dropping to a pre-selected value.

12. A unit as in claim 11 which includes a meter of current flow from the output port.

13. An energy dispensing apparatus comprising:

an outlet control unit with energy monitoring circuitry and an energy dispensing outlet; and

an access control system, wherein the control unit transfers access requesting information to the control system for authentication, and, in response to authentication, the control system transfers a dispensing indicium to the control unit, wherein the control unit, in response to the received dispensing indicium, activates the outlet to dispense electrical energy, and wherein dispensing is terminated in response to the energy monitoring circuitry detecting a predetermined condition.

14. An apparatus as in claim 13 where the control unit includes at least one of a card reader, or, a wireless receiver.

15. An apparatus as in claim 13 where the predetermined condition includes at least one of detecting termination of a current flow, detecting a current flow above a predetermined value, or, detecting a current flow below a different predetermined value.

16. A method comprising:

providing an access credential;

authenticating the credential, and responsive thereto, providing access by initiating a current flow;

monitoring the magnitude of the current flow, and responsive thereto, terminating access in response to at least one of, the current flow terminating, the current flow exceeding a predetermined value, or the current flow declining to a different predetermined value.
