1. A method for automatically selecting a recharging mode of an electric vehicle, the method comprising:
- identifying a first recharging mode by an onboard charger corresponding to a duty cycle of a pulse width modulation signal received from a control pilot port of an external charger;
activating, by the onboard charger, a power line communication controller of a vehicle to perform power line communication with the external charger;
performing, by the onboard charger, a first recharge process corresponding to the identified first recharging mode;
identifying, by the onboard charger, a second recharging mode according to the duty cycle of the pulse width modulation signal received from the external charger when the first recharge process fails; and
automatically selecting, by the onboard charger, a second recharge process corresponding to the second recharging mode when the second recharging mode is identified.

Abstract
A method for automatically selecting a recharging mode of an electric vehicle includes: identifying a first recharging mode corresponding to a duty cycle of a received pulse width modulation signal, performing a first recharge process corresponding to the identified first recharging mode, identifying a second recharging mode according to the duty cycle of the received pulse width modulation signal when the first recharge process fails; and performing a second recharge process corresponding to the second recharging mode when the second recharging mode is identified.

7. A method for automatically selecting a recharging mode of a charger, the method comprising:
-
displaying a predetermined recharging mode selection image for receiving a selection of a recharging mode; displaying a predetermined automatic recharging conversion mode selection image for checking whether a current mode is automatically converted into a second recharging mode when a recharging mode selected via the recharging mode selection image is a first recharging mode; generating and transmitting a pulse width modulation signal by a communication unit having a duty cycle corresponding to the first recharging mode when automatic recharging conversion is activated via the automatic recharging conversion mode selection image; and generating and transmitting a pulse width modulation signal having a duty cycle corresponding to the second recharging mode when a first recharge process corresponding to the first recharging mode fails. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. An electric vehicle recharging system comprising:
-
an onboard charger identifying a recharging mode based on a duty cycle of a pulse width signal received from a control pilot port of an external charger; a power line communication controller of a vehicle being activated by the onboard charger, performing power line communication with the external charger when the identified recharging mode by the onboard charger is a quick recharging mode; and a battery being recharged by the onboard charger with power received from the external charger according to the identified recharging mode, wherein, upon determining, by the power line communication controller, that a predetermined quick recharge process corresponding to the quick recharging mode fails, the onboard charger automatically switches the quick recharging mode into a slow recharging mode based on a duty cycle of the pulse width modulation signal. - View Dependent Claims (15, 16, 17, 18)

19. A charger for automatically selecting a recharging mode, comprising:
-
a display unit displaying a predetermined recharging mode selection image for receiving a selection of a recharging mode and a predetermined automatic recharging conversion mode selection image for determining whether a first charging mode is automatically converted into a second recharging mode when a recharging mode selected via the recharging mode selection image is the first charging mode; a communication unit transmitting and receiving a power line communication signal to and from an electric vehicle, generating a pulse width modulation signal, and transmitting the pulse width modulation signal to the electric vehicle; and a controller controlling the communication unit so as to generate and transmit a pulse width modulation signal having a duty cycle corresponding to the first recharging mode when automatic recharging conversion is activated via the automatic recharging conversion mode selection image, and controlling the communication unit so as to generate and transmit a pulse width modulation signal having a duty cycle corresponding to the second recharging mode when a first recharge process corresponding to the first recharging mode fails. - View Dependent Claims (20, 21, 22, 23, 24)
