ELECTRIC VEHICLE, AND DEVICE AND METHOD FOR CHARGING SAME
First Claim
1. A device for charging an electric vehicle, comprising:
- a charger cable communication unit configured to receive encrypted electric vehicle charging information from an electric vehicle;
a charger security unit configured to decrypt the encrypted electric vehicle charging information; and
a control unit configured to determine whether the decrypted electric vehicle charging information is identical with charger charging information by comparing the decrypted electric vehicle charging information with the charger charging information;
wherein the charger security unit encrypts the charger charging information if the control unit of the device for charging an electric vehicle determines that the decrypted electric vehicle charging information is not identical with the charger charging information;
wherein the charger cable communication unit sends the encrypted charger charging information to the electric vehicle; and
wherein the control unit charges the electric vehicle when an acknowledgement message is received from the electric vehicle in response to the encrypted charger charging information.

Abstract
An electric vehicle and a device and method for charging the electric vehicle are disclosed. The device for charging an electric vehicle includes a charger cable communication unit, a charger security unit, and a control unit. The charger cable communication unit receives encrypted electric vehicle charging information from an electric vehicle. The charger security unit decrypts the encrypted electric vehicle charging information. The control unit determines whether the decrypted electric vehicle charging information is identical with charger charging information. The charger security unit encrypts the charger charging information if the control unit of the device for charging an electric vehicle determines that the decrypted electric vehicle charging information is not identical with the charger charging information. The charger cable communication unit sends the encrypted charger charging information to the electric vehicle. The control unit charges the electric vehicle when an acknowledgement message is received from the electric vehicle.
