Abstract

Claims (50)

1 . A method, comprising:

determining, by a charging station, that a vehicle requests approval to perform a charging operation;

accessing, by the charging station, information stored on the vehicle which includes a charging profile unique to the vehicle;

storing the information accessed from the vehicle at the charging station;

determining, by the charging station, an identity of the vehicle based on the information stored on the vehicle and to approve the charging operation based on the identity of the vehicle;

charging the vehicle at different charging currents based on the charging profile;

determining the charging operation is completed; and

deleting, by the charging station, the information accessed from the vehicle based on the charging operation being completed.

2 . The method of claim 1 , comprising:

prior to the accessing, concealing, by the vehicle, at least a portion of the information.

3 . The method of claim 1 , wherein the charging comprises transmitting a charge, by the charging station to the vehicle, wherein the transmitting is commenced at a first amount of current, and the transmitting progresses to a second amount of current greater than the first amount of current based on the charging profile.

4 . The method of claim 1 , wherein the charging comprises:

processing, by the charging station, an electronic payment for charging the vehicle; and

responsive to the processing, transmitting a charge, by the charging station, to the vehicle.

5 . The method of claim 1 , wherein the information comprises payment account information and personal identification information, and the determining comprises granting approval of the charging operation in response to the payment account information being associated with the personal identification information.

6 . The method of claim 1 , wherein the information comprises a vehicle identification number for the vehicle, the method further comprises encrypting, by the charging station, the vehicle identification number.

7 . The method of claim 1 , further comprising exchanging certificates between the charging station and the vehicle, wherein the determining comprises determining to approve the charging operation based on the certificates.

8 . A system, comprising:

a processor; and

a hardware memory, wherein the processor and the hardware memory are communicably coupled, wherein the processor is configured to:

determine, by a charge station, that a vehicle requests approval to perform a charging operation;

access, by the charge station, information stored on the vehicle which includes a charging profile that is unique to the vehicle;

store the information accessed from the vehicle at the charging station;

determine, by the charge station, an identity of the vehicle based on the information stored on the vehicle and to approve the charging operation based on the identity of the vehicle;

charge the vehicle at different charging currents based on the charging profile;

determine the charging operation is completed; and

delete, from the charge station, information accessed from the vehicle based on the charging operation being completed.

9 . The system of claim 8 , wherein the processor is configured to conceal at least a portion of the information.

10 . The system of claim 8 , wherein the processor is configured to transmit a charge to the vehicle, wherein the processor controls charge to be transmitted at a first amount of current and subsequently progress to a second amount of current greater than the first amount of current.

11 . The system of claim 8 , wherein the processor is configured to process an electronic payment for charging the vehicle, and in response, transmit a charge to the vehicle.

12 . The system of claim 8 , wherein the information comprises payment account information and personal identification information, and the processor is configured to determine comprises granting approval of the charging operation in response to the payment account information being associated with the personal identification information.

13 . The system of claim 8 , wherein the information comprises a vehicle identification number for the vehicle, and the processor is configured to encrypt the vehicle identification number.

14 . The system of claim 8 , wherein the processor is configured to exchange certificates between the charge station and the vehicle, and determine to approve the charging operation based on the certificates.

15 . A non-transitory computer-readable storage medium comprising instructions that, when read by a processor, cause the processor to perform:

determining, by a charging station, that a vehicle requests approval perform a charging operation;

accessing, by the charging station, information stored on the vehicle which includes a charging profile unique to the vehicle;

storing the information accessed from the vehicle at the charging station;

determining, by the charging station, an identity of the vehicle based on the information stored on the vehicle and to approve the charging operation based on the identity of the vehicle;

charging the vehicle at different charging currents based on the charging profile;

determining the charging operation is completed; and

deleting, by the charging station, the information accessed from the vehicle based on the charging operation being completed.

16 . The non-transitory computer-readable storage medium of claim 15 , wherein the processor is further configured to perform:

concealing, by the vehicle, at least a portion of the information.

17 . The non-transitory computer-readable storage medium of claim 15 , wherein the processor is further configured to perform transmitting a charge, by the charging station to the vehicle, wherein the transmitting is commenced at a first amount of current, and the transmitting progresses to a second amount of current greater than the first amount of current based on the charging profile.

18 . The non-transitory computer-readable storage medium of claim 15 , further comprising instructions for:

processing, by the charging station, an electronic payment for charging the vehicle; and

responsive to the processing, transmitting a charge, by the charging station, to the vehicle.

19 . The non-transitory computer-readable storage medium of claim 15 , wherein the information comprises payment account information and personal identification information, and the determining comprises granting approval of the charging operation in response to the payment account information being associated with the personal identification information.

20 . The non-transitory computer-readable storage medium of claim 15 , wherein the processor is further configured to perform:

exchanging certificates between the charging station and the vehicle, wherein the determining comprises determining to approve the charging operation based on the certificates.
