The present invention relates to a portable generator for an electric vehicle. The portable generator produces electric power by receiving running wind generated when an electric vehicle travels in a state of being detachably mounted in the electric vehicle. The portable generator comprises: a power generation unit including a front housing and a rear housing which are mutually coupled to each other so as to form an internal space, a stator which is fixed to the internal space, and a rotor assembly which is rotatably provided at the center of the stator and axially rotates by an external force so as to generate electric power; an impeller unit including an impeller casing which is coupled to the front casing and provides an accommodating space opened to the outside, and an impeller which is mounted inside the impeller casing and rotates by the running wind flowing into the accommodating space so as to axially rotate the rotor assembly; and a fixing device fixing the power generation unit to a vehicle. According to the present invention, the portable generator for an electric vehicle as described above frequently charges a battery by utilizing the running wind generated during running of the vehicle such that the charged amount of the battery can be maintained well and the travelable distance can be increased accordingly. In addition, the structure is simple and compact, and power of a desired voltage can be outputted, thereby being versatile.

    본 발명은 전기차용 포터블 발전기에 관한 것이다. 전기차에 착탈 가능하게 장착된 상태로 전기차의 주행시 발생하는 주행풍을 받아들여 전력을 생산하는 것으로서, 상호 결합하여 내부공간을 형성하는 전방하우징 및 후방하우징과, 상기 내부공간에 고정되는 스테이터와, 상기 스테이터의 중심부에 회전 가능하도록 구비되고 외력에 의해 축회전하여 전력을 발생시키는 로터어셈블리를 포함하는 발전부와; 상기 전방케이싱에 결합하며 외부로 개방된 수용공간을 제공하는 임펠러케이싱과, 상기 임펠러케이싱의 내부에 장착되고 수용공간 내부로 유입한 주행풍에 의해 회전하여 상기 로터어셈블리를 축회전 시키는 임펠러를 구비하는 임펠러부와; 상기 발전부를 차량에 고정시키는 고정장치를 포함한다. 상기와 같이 이루어지는 본 발명의 전기차용 포터블 발전기는, 차량의 주행 중 발생하는 주행풍을 활용해 배터리를 수시로 충전시키므로, 배터리의 충전량을 양호하게 유지할 수 있어 그만큼 주행 가능거리를 늘일 수 있다. 또한, 구조가 간단하며 컴팩트하고 원하는 전압의 전력을 출력할 수 있어 다목적으로 사용 가능하다.
