Disclosed are a driving device using a dual motor and an electric vehicle using the same. The driving device comprises: a first motor operating in a first driving mode; a second motor operating together with the first motor in a second driving mode; a battery providing power to the first motor and the second motor; a first gear coupled to an end of a rotating shaft of the first motor; a second gear coupled to an end of a rotating shaft of the second motor; a first gear unit provided at one end of an output shaft; a second gear unit provided at the other end of the output shaft; a first pulley coupled to the first gear and the first gear unit to transmit a rotational force of the first motor to the output shaft; and a second pulley coupled to the second gear and the second gear unit to transmit a rotational force of the second motor to the output shaft. The distance between the first pulley and the second pulley corresponds to the distance between the first gear and the second gear. Since the dual motor can be driven independently or in combination according to driving modes, the battery can be efficiently operated. 듀얼 모터를 이용한 구동 장치 및 이를 이용한 전기자동차를 개시한다. 본 구동 장치는 제1 구동 모드에서 동작하는 제1 모터, 제2 구동 모드에서 제1 모터와 함께 동작하는 제2 모터, 제1 모터 및 제2 모터로 전력을 제공하는 배터리, 제1 모터의 회전축의 끝단에 결합된 제1 기어, 제2 모터의 회전축의 끝단에 결합된 제2 기어, 출력축의 일단에 구비된 제1 기어 장치, 출력축의 타단에 구비된 제2 기어 장치, 제1 기어와 제1 기어 장치에 결합되어 제1 모터의 회전력을 출력축으로 전달하는 제1 풀리 및 제2 기어와 제2 기어 장치에 결합되어 제2 모터의 회전력을 출력축으로 전달하는 제2 풀리를 포함한다. 제1 풀리 및 제2 풀리 간의 거리는 제1 기어 및 제2 기어 간의 거리에 대응한다.
