Communication Method
First Claim
1. A method of communication between a power supply station and an electric vehicle, the method comprising:
- performing a first preparation in which the electric vehicle prepares a first information represented by a numerical value to be transmitted to the power supply station;
performing a first transmission in which the electric vehicle 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 first correspondence relationship; and
performing a first reception in which the power supply station receives the first information based on a magnitude of the current drawn by the electric vehicle and the first correspondence relationship.
