A method of communication between a power supply station and an electric vehicle is provided. In the method, the electric vehicle prepares a first information represented by a numerical value to be transmitted to the power supply station and transmits the first information by causing an AC power, which the electric vehicle draws from the power supply station, to have a current value corresponding to the first information based on a predetermined correspondence relationship. The power supply station receives the first information based on a magnitude of the current drawn by the electric vehicle and the first predetermined correspondence relationship.
