A method for delivering energy to an electric vehicle is provided, wherein the electric vehicle is associated with a customer account. The method includes identifying the electric vehicle at an energy delivery point, and determining a current balance of the customer account, wherein the current balance includes at least a portion of a prepayment amount based on a predetermined amount of energy to be delivered to the electric vehicle at the energy delivery point. The method also includes delivering energy to the electric vehicle, metering an actual amount of energy delivered to the electric vehicle, and determining a transaction amount based on the actual amount of energy delivered to the electric vehicle at the energy delivery point.

1. A method for delivering energy to an electric vehicle, said method comprising: identifying, by an energy point server system, the electric vehicle at an energy delivery point, wherein the electric vehicle is associated with a customer account;determining, by the energy point server system, a current balance of the customer account, wherein the current balance includes at least a portion of a prepayment amount based on a predetermined amount of energy to be delivered to the electric vehicle at the energy delivery point;delivering energy to the electric vehicle;metering, by the energy point server system and the electric vehicle, an actual amount of energy delivered to the electric vehicle;comparing the amount of delivered energy metered by the energy point server system and the electric vehicle;determining, by the energy point server system, a transaction amount based on a first billing rate for the actual amount of energy delivered to the electric vehicle at the energy delivery point;determining, by the energy point server system, whether the transaction amount exceeds the current balance of the customer account; andapplying, by the energy point server system, a second billing rate for the actual amount of energy delivered to the electric vehicle when the transaction amount exceeds the current balance of the customer account. 2. The method in accordance with claim 1, further comprising receiving the prepayment amount in response to a bill corresponding to the predetermined amount of energy to be delivered. 3. The method in accordance with claim 1, wherein identifying the electric vehicle at an energy delivery point comprises reading a unique identifier from a passive tag embedded in the electric vehicle and associated with the customer account using a scanner. 4. The method in accordance with claim 1, wherein identifying the electrical vehicle at an energy delivery point comprises receiving a unique identifier associated with the electric vehicle and the customer account via an actively powered wireless link. 5. The method in accordance with claim 1, wherein identifying the electric vehicle at an energy delivery point comprises receiving a unique identifier associated with the electric vehicle and the customer account via a physical connection between the electric vehicle and the energy delivery point. 6. The method in accordance with claim 1, further comprising denying service at the energy delivery point when the current account balance is less than a threshold amount. 7. The method in accordance with claim 1, wherein when the current balance is less than the transaction amount, said method further comprises crediting the customer account with the difference between the transaction amount and the current balance. 8. The method in accordance with claim 7, wherein crediting the customer account with the difference between the transaction amount and the current balance further comprises applying a second billing rate for the difference between the actual amount of energy delivered to the electric vehicle and the current balance of the customer account. 9. The method in accordance with claim 1, further comprising generating a confirmation, by a meter within the electric vehicle, that the amount of energy delivered was received by the electric vehicle. 10. The method in accordance with claim 1, wherein applying a second billing rate comprises applying a second billing rate for the difference between the actual amount of energy delivered to the electric vehicle and the current balance of the customer account when the transaction amount exceeds the current balance of the customer account. 11. A system for providing energy to an electric vehicle, said system comprising: an energy delivery point configured to receive a unique identifier embedded in the electric vehicle, deliver energy to the electric vehicle, meter, by the energy point and the electric vehicle, an actual amount of energy delivered to the electric vehicle, and compare the amount of delivered energy metered by the energy point and the electric vehicle; anda server coupled to said energy delivery point, said server configured to:receive the unique identifier from said energy delivery point;identify the electric vehicle based on the unique identifier, wherein the electric vehicle is associated with a customer account;determine a current balance of the customer account, wherein the current balance includes at least a portion of a prepayment amount associated with a predetermined amount of energy to be delivered to the electric vehicle by said energy delivery point;determine a transaction amount based on a first billing rate for the actual amount of energy delivered to the electric vehicle;determine whether the transaction amount exceeds the current balance of the customer account; andapply a second billing rate for the actual amount of energy delivered to the electric vehicle when the transaction amount exceeds the current balance of the customer account. 12. The system in accordance with claim 11, wherein said server is configured to receive the prepayment amount in response to a bill corresponding to the predetermined amount of energy to be delivered. 13. The system in accordance with claim 11, wherein said energy delivery point is configured to receive the unique identifier from the electric vehicle via one of a wireless link and a physical connection. 14. The system in accordance with claim 11, wherein said server is configured to deny service at said energy delivery point when the current account balance is less than a threshold amount. 15. The system in accordance with claim 11, wherein said server is configured to credit the customer account with the difference between the transaction amount and the current balance when the current balance is less than the transaction amount. 16. The system in accordance with claim 11, wherein a confirmation that the amount of energy delivered was received by the electric vehicle is generated by a meter within the electric vehicle. 17. A system comprising: a controller coupled to an energy delivery point and a database, said controller programmed to: receive a unique identifier from the energy delivery point, wherein the unique identifier is acquired by the energy delivery point from an electric vehicle;identify the electric vehicle based on the unique identifier, wherein the electric vehicle is associated with a customer account;determine a current balance of the customer account, wherein the current balance includes at least a portion of a prepayment amount associated with a predetermined amount of energy to be delivered to the electric vehicle by the energy delivery point;receive, from the energy delivery point, an actual amount of energy delivered to the electric vehicle, wherein the amount of energy delivered is metered by the energy delivery point and by the electric vehicle;compare the amount of delivered energy metered at the energy delivery point and at the electric vehicle;determine a transaction amount based on a first billing rate for the actual amount of energy delivered to the electric vehicle;determine whether the transaction amount exceeds the current balance of the customer account; andapply a second billing rate for the actual amount of energy delivered to the electric vehicle when the transaction amount exceeds the current balance of the customer account. 18. The controller in accordance with claim 17, wherein said controller is further programmed to receive the prepayment amount in response to a bill corresponding to the predetermined amount of energy to be delivered. 19. The controller in accordance with claim 17, wherein said controller is further programmed to determine the customer account associated with the unique identifier using said database. 20.
