Abstract

A combined parking meter and electric energy dispensing apparatus and method can automatically provide, in response to receiving a payment, either parking time or electric energy. When electric current is being consumed by a connected electric vehicle, the invention operates in an electric energy dispensing mode and allocates a received payment thereto. When no electric current flows from the apparatus, then the invention functions in a parking meter mode and allocates the received payment thereto.

Claims

1. Combined parking meter and electric energy dispensing apparatus, comprising:

means for receiving a payment;

means for conducting electric current from a primary electric power source to an electric energy storage device;

means for sensing when electric current is conducted through said means for conducting to the electric energy storage device; and

means for allocating a received payment as an electric energy dispensing fee in response to said means for sensing sensing electric current through said means for conducting, and as a parking time fee in response to said means for sensing not sensing electric current through said means for conducting.

2. An apparatus as defined in claim further comprising a housing having all said means disposed therein, said housing disposed at a parking space for an electric motorized vehicle.

3. Combined parking meter and electric energy dispensing apparatus, comprising:

conductor means for connecting to an electric energy storage device in a vehicle;

means for receiving from a user of said apparatus a specific payment which is at the time of receipt indeterminate to said apparatus as to whether said payment is for parking time or for electric power;

means for converting the amount of said payment to both an equivalent parking time amount and an equivalent electric power amount;

means, responsive to said means for converting, for defining both an unused total parking time amount and an unused total electric power amount;

means for sensing when electric current is conducted through said conductor means; and

means for decreasing said unused total parking time amount by an actual elapsed time amount in response to said means for sensing not sensing electric current through said conductor means and for decreasing said unused total electric power amount by an actual consumed electric power amount in response to said means for sensing sensing electric current through said conductor means.

4. An apparatus as defined in claim 3, wherein said means for decreasing also decreases said unused total electric power amount by a predetermined amount in response to said means for sensing not sensing electric current through said conductor means and further wherein said means for decreasing also decreases said unused total parking amount to zero in response to said means for sensing sensing electric current through said conductor means.

5. An apparatus as defined in claim 4, further comprising a housing having all said means disposed therein, said housing disposed at a public parking space for the vehicle.

6. A method of automatically providing either parking time or electric power for an electric vehicle at a public parking space, comprising:

receiving at the public parking space a payment to be allocated automatically either as a fee for parking time or as a fee for electric power for the vehicle;

connecting at the public parking space a primary electric power source to an electric conductor adapted to be connected to an electric energy storage device in the vehicle;

sensing at the public parking space whether electric current is conducted through the electric conductor;

allocating at the public parking space a received payment as an electric energy dispensing fee in response to electric current being conducted through the electric conductor; and

allocating at the public parking space a received payment as a parking time fee in response to electric current not being conducted through the electric conductor.

7. A method as defined in claim 6, wherein:

at the time of receiving the payment, it is indeterminate as to whether the payment is for parking time or for electric power; and

said allocating includes;

converting the amount of the payment to both an equivalent parking time amount and an equivalent electric power amount;

defining, in response to the equivalent parking time amount and the equivalent electric power amount, respectively, both an unused total parking time amount and an unused total electric power amount; and

decreasing the unused total parking time amount by an actual elapsed time amount in response to not sensing electric current and decreasing the unused total electric power amount by an actual consumed electric power amount in response to sensing electric current.

8. A method as defined in claim 7, wherein said allocating further includes decreasing the unused total electric power amount by a predetermined amount in response to not sensing electric current and decreasing the unused total parking amount to zero in response to sensing electric current.

9. A method as defined in claim 8, further comprising performing said steps in response to operating a programmed computer disposed in a housing at the parking space.

10. A method as defined in claim 6, further comprising performing said steps in response to operating a programmed computer at the parking space.
