Electric vehicle charging system and method thereof for providing diagnostic services
The present invention presents a method providing an additional service during electric vehicle charging by (a) the electric vehicle charger ( 200 ) detecting connection with an electric vehicle ( 100 ) via a charging cable; (b) the electric vehicle charger ( 200 ) exchanging charging messages through a charging port in a PLC modem, when the connection is detected in step (a); and (c) the electric vehicle charger ( 200 ) providing an additional service for the electric vehicle once the charging begins, and therefore, providing additional services such as software updates, vehicle contents updates requested by a driver during the charging of the electric vehicle, and thus providing convenience for the car owners without visiting car diagnostic service center.
1. A method of charging an electric vehicle and providing an additional service by an electric car charger comprising:
a) detecting a connection between the electric vehicle and the car charger via the charging cable of the electric car charger;
b) exchanging charging messages between the electric vehicle and the electric car charger through a charging port in a PLC modem, when the connection is detected in step a);
c) providing an additional service for the electric vehicle once the charging begins;
(c-1) detecting connection attempts by the electric vehicle via a port for an additional service in PLC modem;
(c-2) opening the additional service port and connecting to the electric vehicle;
(c-3) notifying the connection of the electric vehicle to a back-end server when connection to the electric vehicle is completed;
(c-4) receiving a vehicle diagnostic script from the back-end server and a request for an additional service from a customer;
(c-5) diagnosing the electric vehicle based on the vehicle diagnostic script, collecting multiple information from the electric vehicle to form a diagnostic log, and saving the diagnostic log in the back end server; and
(c-6) providing the diagnostic log and a task performing report of the requested additional service from the back end server to a driver terminal.
2. The method of claim 1 , wherein step (c-2) comprises:
(c-2-1) the electric vehicle finding the PLC modem of the electric vehicle charger;
(c-2-2) the electric vehicle charger operating as a TCP server to detect the electric vehicle as a customer and requesting a UDP after the progressing of slack; and
(C-2-3) the electric vehicle charger receiving a TCP/IP message from the electric vehicle and connecting with the electric vehicle through TCP/IP.
3. The method of claim 1 , wherein the electric vehicle charger receives a request from a driver in step (c-4), performs the request in step (c-5), and generates the task performing report.
