Abstract

Disclosed is an add-on communication apparatus attached to an in-cable charging control device integrated with a cable assembly to charge an electric vehicle. The add-on communication apparatus includes a first communication module to make wireless communication with a terminal, a second communication module to make wireless communication with the in-cable charging control device, and a control module. The control module receives a command from the terminal through the first communication module, generates a first control command based on the command, and transmits the first control command to the in-cable charging control device through the second communication module.

Claims

1. A communication apparatus attached to an in-cable charging control device, the in-cable changing control device integrated with a cable assembly for charging an electric vehicle, the apparatus comprising:

a first communication module to perform wireless communication with a terminal;

a second communication module to perform wireless communication with the in-cable charging control device; and

a control module

to receive a command from the terminal via the first communication module, to generate a first control command based on the received command, and to transmit the generated first control command to the in-cable charging control device via the second communication module.

2. The apparatus of claim 1, wherein the control module is further to:

receive configuration information from the terminal via the first communication module;

generate a second control command corresponding to the first control command based on setting information; and

transmit the second control command to the in-cable charging control device via the second communication module.

3. The apparatus of claim 2, wherein:

the configuration information is related to an acceptable amount of charging of the electric vehicle;

the received command

and the first control command represent starting of the charging of the electric vehicle;

the second control command represents stopping of the charging of the electric vehicle; and

the control module is further to generate the second control command when a quantity of power supplied to the electric vehicle reaches the acceptable amount of charging.

4. The apparatus of claim 3, wherein:

the configuration information is related to the acceptable amount of charging for a home area and a public area; and

the control module is further to;

generate the second control command when a present location is the home area and the quantity of the power supplied to the electric vehicle reaches the acceptable amount of charging for the home area; and

generate the second control command when the present location is the public area and the quantity of the power supplied to the electric vehicle reaches the acceptable amount of charging for the public area.

5. The apparatus of claim 1, wherein the received command represents starting of the charging of the electric vehicle.

6. The apparatus of claim 5, wherein the control module is further to:

obtain a present location of the electric vehicle; and

generate the first control command based on the received command and the obtained present location.

7. The apparatus of claim 6, wherein the present location is either a home area or a public area.

8. The apparatus of claim 7, wherein:

the first control command represents starting of the charging of the electric vehicle; and

the control module is further to;

generate the first control command representing starting of the charging in a low-speed charging mode if the present location is the home area; and

generate the first control command representing starting of the charging in a high-speed charging mode if the present location is the public area.

9. The apparatus of claim 1, wherein the control module is further to:

receive a response to the first control command from the in-cable charging control device via the second communication module; and

transmit the received response to the terminal via the first communication module.

10. The apparatus of claim 9, wherein:

the received command represents a request for charging-related information related to the electric vehicle; and

the response comprises the charging-related information.

11. The apparatus of claim 10, wherein the charging-related information comprises information related to at least the electric vehicle or the cable assembly.

12. The apparatus of claim 11, wherein the information related to the cable assembly comprises information related to at least a charging operation of the cable assembly, a use history of the cable assembly, a state of the cable assembly, or a failure of the cable assembly.

13. The apparatus of claim 12, wherein the information related to the state of the cable assembly comprises information related to at least a state of a relay in the cable assembly, a fusion state of the relay, a temperature of the cable assembly, electric leakage of the cable assembly, disconnection of the cable assembly, or a surrounding environment of the cable assembly.

14. The apparatus of claim 11, wherein the information related to the electric vehicle comprises at least an initial charging state, a present charging state, a charging start time, an estimated charging finish time, an actual charging finish time, charging status information about the electric vehicle, charging error information about the electric vehicle, information related to a quantity of power supplied to the electric vehicle, or information related to an intensity of a current supplied to the electric vehicle.
