The present invention relates to a four wheel steering-available electric vehicle, which can increase power efficiency by having a high-efficient generator mounted therein. According to an embodiment of the present specification, an electric vehicle comprises: an electric motor for driving front wheels; a battery for storing electric energy for driving the electric motor; a generator for converting the rotational energy of rear wheels into electric energy and supplying the electric energy to the battery or the electric motor; a flywheel connected to the rear wheels by a first pulley and connected to the generator by a second pulley; and a controller for monitoring and controlling the charge/discharge state of the battery, monitoring the required power of the electric motor, and performing control so that the battery is charged with the electric energy generated by the generator, or the electric energy is directly supplied to the electric motor. The rear wheels and the flywheel have substantially the same gear ratio and are connected by the first pulley. The flywheel has a higher gear ratio than the generator, and the flywheel and the generator are connected by the second pulley.

    본 발명은 고효율의 발전기를 탑재하여 전력효율이 향상된 4륜 조향이 가능한 전기자동차에 관한 것이다. 본 명세서의 일실시예에 따른 전기자동차는 전륜휠을 구동하는 전동기; 상기 전동기를 구동하기 위한 전기에너지가 저장되는 배터리; 후륜휠의 회전에너지를 전기에너지로 변환하여 상기 배터리 또는 상기 전동기로 전기에너지를 공급하는 발전기; 상기 후륜휠과 제1 풀리로 연결되며, 상기 발전기와 제2 풀리로 연결되는 플라이휠; 및 상기 배터리의 충방전 상태를 모니터링하여 제어하며, 상기 전동기의 요구 전력을 모니터링하여 상기 발전기에서 생성된 전기에너지를 상기 배터리로 충전하거나 상기 전동기로 직접 공급되도록 제어하는 제어기를 포함하며, 상기 후륜휠과 상기 플라이휠은 실질적으로 동일한 기어비로 구성되어 상기 제1 풀리로 연결되며, 상기 플라이휠과 상기 발전기는 상기 플라이휠의 기어비가 더 높게 구성되어 상기 제2 풀리로 연결되는 것을 특징으로 한다.
