COMMUNICATION SYSTEM, COMMUNICATION METHOD, RELAYING DEVICE, AND RECORDING MEDIUM

摘要

A communication system between a vehicle and a communication device is disclosed. The vehicle transmits electricity supply information in an A-method to a relaying device like an electricity supply device through an electricity supply line. The electricity supply device receives the electricity supply information in the A-method, then, based on the electricity supply information in the A-method, generates electricity supply information in a B-method, and transmits to the communication device the electricity supply information obtained by conversion into the B-method. The communication device transmits electricity supply information in the B-method to the electricity supply device. The electricity supply device receives the electricity supply information in the B-method, then, based on the received electricity supply information in the B-method, generates electricity supply information in the A-method, and transmits the electricity supply information obtained by conversion into the A-method, to the vehicle through the electricity supply line.
