Abstract

Disclosed are an in-cable control box for charging an electric vehicle and a scheduled charging method thereof. The in-cable control box includes an input unit that receives selection of a charging mode and settings according to the charging mode; a display unit that displays a charging state; a warning unit that outputs a warning sound corresponding to change in the charging state; a power supply that supplies electric power to an on-board charger of an electric vehicle; and a controller that regulates electric power from the power supply to the on-board charger according to the charging mode and settings received through the input unit, controls the display unit to display a charging state, and controls the warning unit to output a warning sound corresponding to change in the charging state.

Claims

1. An in-cable control box comprising:

an input unit that receives selection of a charging mode and settings according to the charging mode;

a display unit that displays a charging state;

a warning unit that outputs a warning sound corresponding to change in the charging state;

a power supply that supplies electric power to an on-board charger of an electric vehicle; and

a controller that regulates electric power from the power supply to the on-board charger according to the charging mode and settings received through the input unit, controls the display unit to display a charging state, and controls the warning unit to output a warning sound corresponding to change in the charging state.

2. The in-cable control box according to claim 1, wherein the controller regulates the electric power supplied from the power supply to the on-board charger according to scheduled settings when a scheduled mode is input through the input unit, and cuts off the electric power supplied from the power supply to the on-board charger when charging of the on-board charger becomes impossible before a termination time according to the scheduled settings is reached.

3. The in-cable control box according to claim 1, further comprising:

a sensing unit for sensing failure of the in-cable control box,

wherein the controller cuts off the electric power supplied from the power supply to the on-board charger, controls the display unit to display the kind of failure, and controls the warning unit to output a warning sound corresponding to the kind of failure, when the sensing unit senses failure of the in-cable control box.

4. The in-cable control box according to claim 1, further comprising:

an emergency power unit for supplying emergency power to the in-cable control box,

wherein the controller controls the emergency power unit to supply electric power to the in-cable control box, and controls the warning unit to output a warning sound, when supply of the electric power to the in-cable control box is stopped.

5. The in-cable control box according to claim 1, further comprising:

a communication unit for communicating with a user terminal,

wherein the controller transmits information about the charging state to the user terminal through the communication unit.

6. The in-cable control box according to claim 5, wherein the controller regulates the electric power supplied from the power supply to the on-board charger according to the charging mode and the settings received from the user terminal, when the selection of a charging mode and the settings according to the charging mode are received from the user terminal through the communication unit.

7. A scheduled charging method of an in-cable control box, comprising:

by a controller, receiving a scheduled mode and settings including at least one of a charging start time, a charging termination time and a charge amount according to the scheduled mode;

by the controller, checking a state of an on-board charger of an electric vehicle and determining whether charging is possible when the charging start time according to the settings is reached; and

by the controller, supplying electric power to the on-board charger until the charging termination time according to the settings is reached.

8. The scheduled charging method according to claim 7, further comprising:

displaying a charging state; and

outputting a warning sound corresponding to change in the charging state.

9. The scheduled charging method according to claim 7, further comprising:

sensing failure of the in-cable control box; and

by the controller, cutting off electric power supplied to the on-board charger, displaying the kind of failure, and outputting a warning sound corresponding to the kind of failure, when the failure is sensed.
