The present invention relates to an electric motorcycle with improved battery efficiency and, more specifically, to a technology which can enhance available mileage through enhancement of efficiency in accordance of a battery storage space and can increase use period of a battery by preventing the complete discharge of a main battery which supplies power in a motorcycle using electricity as a driving force. The electric motorcycle comprises: a main body unit in which a saddle and a handle are installed on a frame in which a steering front wheel and a driving rear wheel are installed; power generation units installed at the steering front wheel and the driving rear wheel of the main body unit, respectively, to generate electricity; an electricity storage unit applied with a lithium ion battery so as to store the electricity generated by the power generation units therein; and a driving unit receiving the electricity of the electricity storage unit to rotate the driving rear wheel, wherein the electricity storage unit comprises the main battery and an assistant battery. The electric motorcycle further comprises: a residual power check unit checking residual electric power of the main battery; and a power supply control unit performing a control operation for switching to the assistant battery when the residual electric power of the main battery reaches 10%.

    본 발명은 배터리 효율이 개선된 전동 오토바이에 관한 것으로서, 더욱 구체적으로는 전기의 힘을 구동력으로 사용하는 오토바이에서 전원을 공급하는 메인배터리가 완전히 방전되는 것을 방지하여, 배터리 저장공간에 따른 효율성을 높여 주행가능거리를 향상시키고, 배터리의 사용기한을 늘릴 수 있는 기술에 관한 것이다. 즉, 본 발명은 조향용 전륜 및 구동용 후륜이 설치되는 프레임의 안장과 핸들이 설치되는 본체부와, 상기 본체부의 조향용 전륜 및 구동용 후륜에 각각 설치되어 전기를 생성하는 발전부와, 상기 발전부의 생성된 전기가 저장되도록 리튬이온전지로 적용되는 축전부와, 상기 축전부의 전기를 제공받아 구동용 후륜을 회전시키는 구동부;로 이루어지며, 상기 축전부는 메인배터리와 보조배터리로 구성되고, 상기 메인배터리의 전원 잔량을 체크하는 잔량체크부와, 상기 메인배터리의 전원 잔량이 10%에 도달하였을 때 보조배터리로 전환되도록 제어하는 전원공급 제어부;를 포함하여 이루어지는 것을 특징으로 한다.
