SYSTEM AND METHOD FOR SENDING/RECEIVING DATA AT CHARING EV

摘要

PURPOSE: A system and method for transmitting and receiving data when charging an electric vehicle are provided to charge the vehicle, to transmit the various kinds of available information for the vehicle through power line communication, and to receive available information in the vehicle through the communication. CONSTITUTION: A system for transmitting and receiving data when charging an electric vehicle includes an estimated charging time analyzing module (100), a data determining module (200), communication equipment (300), a first data storing part (400), a second data storing part (500), and an outputting part (600). When starting to charge the vehicle, the estimated charging time analyzing module calculates an estimated charging time based on a state of charge (SOC) value obtained shortly before through controller area network (CAN) communication. Based on information from the estimated charging time analyzing module, the data determining module is capable of transmitting and receiving the data, and sorts the size of the transmittable data considering a transmitting speed. The communication equipment facilitates data transmission/reception between the vehicle and a center. The first data storing part inside the vehicle stores information about telematics. The second data storing part inside the center stores the information about the telematics. The outputting part outputs data information determined by the data determining module.
