Zusammenfassung:	The present invention relates to a method for transmitting battery state information of an electric vehicle. The method for transmitting the battery state information of the electric vehicle comprises the following steps of: selecting a certain region among an amplitude of a pulse width modulation (PWM) signal for pilot communication transmitted from the electric vehicle (13) to a charger; mapping the selected region to a battery state; and transmitting the PWM signal, of which the selected region is converted, to the charger (12). According to the present invention, the battery state of the electric vehicle is detected and transmitted through the PWM signal for pilot communication. 본 발명은 전기 자동차의 배터리 상태 정보 전달 방법에 관한 것이다. 전기 자동차의 배터리 상태 정보 전달 방법은 전기 자동차(13)로부터 충전기로 전송되는 파일럿 통신을 위한 PWM(Pulse Width Modulation) 신호의 진폭 중 일정 영역을 선택하는 단계; 선택된 일정 영역을 배터리 상태와 매핑을 시키는 단계; 및 선택된 영역이 변환된 PWM 신호를 충전기(12)로 전송하는 단계를 포함한다.
