A charging control device of an electric vehicle can include a charge sequence port to which a charging sequence signal is input; a first controller configured to periodically operate in a wake-up state and a sleep state, and to output a wake-up signal when the charging sequence signal is input in the wake-up state; a second controller configured to operate in a wake-up state when the wake-up signal is output during maintaining of a sleep state; a first power supply configured to supply a first driving voltage to the first controller; and a second power supply disposed configured to supply a second driving voltage to the second controller when the wake-up signal is generated. Also, the second controller is configured to control a charging operation of the electric vehicle in the wake-up state.

Charging control device for electric vehicle

A device for charging an electric vehicle includes a charging inlet for receiving charging information and power from electric vehicle supply equipment (EVSE); a control module for determining a charging mode on the basis of the charging information, and outputting a control signal according to the determined charging mode; and a charging unit for charging a battery of the electric vehicle according to the control signal from the control module.

Device and method for charging electric vehicle with different charging standards

Provided is an apparatus for detecting malfunction, the apparatus detecting malfunction of a display device for displaying a charging state of a vehicle battery according to a control signal. The apparatus for detecting malfunction according to an embodiment of the present invention comprises: an interrupt generation unit for generating an interrupt signal if the control signal satisfies a preset event; a voltage detection unit for detecting a voltage value of the control signal by converting an analog value of the control signal into a digital value; and a determination unit for detecting at least one among whether or not the display device has malfunction and a malfunction type on the basis of at least one among whether or not the display device operates, whether or not the interrupt signal is generated, and the voltage value of the control signal.

Apparatus for detecting malfunction and method therefor

The embodiment relates to a charging control device for an electric vehicle. An electric vehicle charging control device according to an embodiment includes: a charge sequence port to which a charging sequence signal is input from a connector of a charging cable; a first power supply for supplying a first driving voltage; a first controller which is driven on the basis of the first driving voltage, repeats a wake-up state and a sleep state periodically, and generates a wake-up signal when the charging sequence signal is input to the charge sequence port in a wake-up state; a second controller for maintaining a sleep state and operating in a wake-up state when the wake-up signal is generated during the maintaining of the sleep state, and for controlling a charging operation of the electric vehicle in the wake-up state; and a second power supply, disposed between the first controller and the second controller, for providing a second driving voltage to the second controller when the wake-up signal is generated, wherein the charging sequence signal is selectively received in the wake-up state of the first controller.

A device for charging an electric vehicle according to an embodiment of the present invention comprises: a charging inlet for receiving charging information and power from electric vehicle supply equipment (EVSE); a control module for determining a charging mode on the basis of the charging information, and outputting a control signal according to the determined charging mode; and a charging unit for charging a battery of the electric vehicle according to the control signal from the control module.

Device and method for charging electric vehicle

A charging control device for charging an electric vehicle according to one embodiment of the present invention comprises: a first switch unit for receiving a first control signal from the outside; a first control unit for receiving the first control signal through the first switch unit; a second switch unit for receiving a second control signal from the outside; a second control unit which is woken up by the first control unit and receives the second control signal through the second switch unit; and a motor control unit which is controlled by the second control unit and controls driving of a motor for a charging flap, wherein the second control unit disables the first switch and enables the second switch when the second control unit is woken up by the first control unit.
