  • ELECTRIC VEHICLE, AND DEVICE AND METHOD FOR CHARGING SAME
    Publication number: 20150210175
    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.
