Add-on communication apparatus attached to cable installment type charging control apparatus and method thereof
First Claim
1. An add-on communication device attached to a cable-mounted charging control device attached to a cable assembly for charging an electric vehicle, the add-on communication device comprising:
- a charging control device communication unit configured to communicate with the cable-mounted charging control device, wherein the charging control device communication unit comprises an infrared light-emitting diode and an infrared light-receiving diode;
a terminal device communication unit configured to communicate with a terminal device wherein the terminal device communication unit comprises a plurality of communication modules including an infrared communication module, a BLUETOOTH communication module, a wireless local area network (WLAN) communication module, and a wireless wide area network (WWAN) communication module; and
a control unit configured to;
control the charging control device communication unit and the terminal device communication unit;
assign priority orders to the plurality of communication modules in order of the infrared communication module, the BLUETOOTH communication module, the WLAN communication module, and the WWAN communication module such that the infrared communication module is assigned with a highest priority order and the WWAN communication module is assigned with a lowest priority order among the plurality of communication modules;
generate a message;
determine a first communication module for transmitting the message from among the plurality of communication modules;
determine a second communication module for transmitting the message from among the plurality of communication modules other than the first communication module when it is determined that transmitting the message via the first communication module will be unsuccessful; and
transmit the message to the terminal device via the determined one of first communication module and second communication module,wherein the first communication module and the second communication module are determined on the basis of the priority orders assigned to the plurality of communication modules.

Abstract
An add-on communication device attached to a cable-mounted charging control device integrated with a cable assembly for charging an electric vehicle includes a control unit and a plurality of communication modules for communicating with a terminal device. The control unit determines a first communication module for transmitting a message, from among the plurality of communication modules. The control unit determines a second communication module for retransmitting the message, from among the plurality of communication modules excepting the first communication module, when reception of an acknowledgement message indicating normal reception of the message by the terminal device is abnormal.
