According to the present invention, a battery heater for an electric vehicle comprises: an extrusion molding (10); a heating pad (20) wherein a heating wire (22) is fixed and arranged on felt fabric (24) in a prescribed pattern; an adhesion means (30) to fix the heating pad (20) on the extrusion molding (10); a terminal wire (40) connected to both ends of the heating wire (22) to be connected to a power supply; and a sealing material (50) to seal a connection portion of the heating wire (22) and the terminal wire (40). The battery heaters for an electric vehicle are arranged on a lower portion of a battery cell in a battery pack for a vehicle at regular intervals and are electrically connected in series to directly heat the battery cell to stably maintain battery performance.

    본 발명은 전기차용 배터리 히터로, 압출 몰딩(10); 열선(22)이 펠트 원단(24)상에 소정의 패턴으로 고정 배치된 발열패드(20); 상기 발열패드(20)를 상기 압출 몰딩(10)에 고정하기 위한 접착수단(30); 상기 열선(22)의 양단에 접속되어 전원으로 연결되는 단자선(40); 및 상기 열선(22)과 단자선(40)의 접속부위를 밀봉하기 위한 실링재(50)를 포함하여 이루어지며, 전기차용 배터리 팩 내부에 배터리 셀 하부에 일정 간격으로 배치되고 전기적으로 직렬연결되어 직접적으로 배터리 셀을 가열하는 것에 의해 배터리 성능을 안정적으로 유지할 수 있도록 되어 있다.
