Abstract

An electric charge fee calculation and collection system for an electric vehicle includes a charge control unit that receives power from a power supply means and charges a battery of the vehicle; a power usage amount and cost calculation unit that measures a power usage amount supplied to the battery from the power supply means and calculates an electricity rate corresponding to the measured power usage amount; and a collection means that collects the electricity rate from a user.

Claims

1. A system for calculating and collecting an electric charge fee for an electric vehicle, the system comprising:

a charge control unit that receives power from a power supply means and charges a battery;

a power usage amount and cost calculation unit that measures a power usage amount supplied to the battery from the power supply means and calculates an electricity rate corresponding to the measured power usage amount; and

a collection means that collects the electricity rate from a user.

2. The system of claim 1, wherein the charge control unit comprises:

a plug that is to be electrically connected to the power supply means; and

a charge unit which charges the battery by using power supplied from the power supply means while being connected with the plug.

3. The system of claim 1, wherein the power usage amount and cost calculation unit comprises:

a power usage amount measuring unit that measures a power usage amount supplied from the power supply means to the battery;

a database that stores information about electricity rate according to power usage amount; and

an electricity rate calculation unit that calculates an electricity rate for a preset time period or at each charge from a power usage amount for a preset time period or at each charge, on the basis of the information stored in the database.

4. The system of claim 3, further comprising a double metering blocking unit which delivers a metric prohibition request signal to the power supply means.

5. The system of claim 4, wherein the metric prohibition request signal includes a power usage amount of a vehicle and specific information of the vehicle.

6. The system of claim 5, wherein the power supply means comprises:

an outlet that is to be electrically connected to the plug of the charge control unit;

a power supply unit that supplies power to a power use device through the outlet;

a metering unit that measures a power usage amount supplied to the power use device from the power supply unit;

a data receiving unit that receives the metric prohibition request signal from the double metering blocking unit;

a database which stores the power usage amount and the specific information of the vehicle included in the metric prohibition request signal; and

a power usage amount calculation unit which deducts the power usage amount included in the metric prohibition request signal from the power usage amount measured in the metering unit.

7. The system of claim 4, wherein the collection means comprises:

a data transmission unit that delivers an electricity rate generated in a preset time period or at each charge to an electronic payment means of a user for payment request;

a data receiving unit that receives an electricity rate payment success signal or an electricity rate payment failure signal from the electronic payment means; and

a controller that updates the electricity rate record for a preset period stored in the database 24 with the newly paid electricity rate if the payment success signal is received from the electronic payment means, while delivering a charge prohibition request signal to the charge control unit if the payment failure signal is received from the electronic payment means.

8. The system of claim 4, wherein the collection means comprises:

a data transmission unit that delivers an electricity rate generated in a preset time period or at each charge to a cellular phone center or a vehicle information center for payment request;

a data receiving unit that receives an electricity rate payment success signal or an electricity rate payment failure signal from the cellular phone center or the vehicle information center; and

a controller that updates the electricity rate record for a preset period stored in the database 24 with the newly paid electricity rate if the payment success signal is received from the cellular phone center or the vehicle information center, while delivering a charge prohibition request signal to the charge control unit if the payment failure signal from the electronic payment means.

9. The system of claim 8, wherein the cellular phone center or the vehicle information center delivers a power usage amount by preset period of a particular vehicle to a power supply company center, and the power supply means delivers a power usage amount and the metric prohibition request signal including the specific information of the vehicle to the power supply company center such that the power supply company center may determine whether the two power usage amounts.
