A failure detection method in a charging connector locking system includes transmitting, by the main controller, an initial command that is received from the charge controller to the locking device; monitoring, by the main controller, whether the initial command is normally executed by the locking device; and determining, by the main controller, whether a failure occurs in the locking device by monitoring whether the initial command is executed while transmitting, to the locking device, a lock command and an unlock command alternately at predetermined time intervals within a predetermined number of times when the initial command is not normally executed, thereby determining the failure of the locking device with high accuracy.

Failure detection method in charging connector locking system

A method is provided for controlling engagement between a vehicle and a charging device includes: attempting to discover a charging device; when the charging device is discovered, identifying the discovered charging device on a list of charging equipment stored in the vehicle; determining a charging history count of the discovered charging device according to the stored list of charging equipment; when the charging history count of the discovered charging device is greater than or equal to a predetermined number, performing a charging operation with the discovered charging device; and when the charging history count of the discovered charging device is less than the predetermined number, performing a Signal Level Attenuation Characterization (SLAC) procedure against the discovered charging device.

Apparatus and method for charging electric vehicle

A method and charging system for effectively performing measurement of a pulse width modulation (PWM) signal for selection of a charging mode between an electric vehicle and a charger are disclosed. The method for determining a charging mode of an electric vehicle includes measuring a duty ratio of a control signal applied to a communication line of a charger connector by a first controller for controlling slow charging and a second controller for controlling quick charging, transmitting measurement results obtained from each of the first controller and the second controller to a third controller in charge of a battery, determining a final duty ratio using the measurement results by the third controller, transmitting the determined final duty ratio to the first controller and the second controller, and starting charging in a mode corresponding to the final duty ratio.
