According to the present invention, a hybrid electric vehicle comprises: a driving unit to drive a driving wheel; a motor supplying a driving force to the driving unit in case of low speed driving; an engine supplying the driving force to the driving unit in case of high speed driving; a battery supplying a current to the motor; a generator charging the battery with power generated in the engine; a control unit controlling operation of the motor, the engine, and the generator; an exhaust pipe discharging exhaust gas generated in the engine to the outside; and a thermoelement having a heating unit receiving heat of the exhaust gas flowing at an internal side of the exhaust pipe and a cooling unit cooled by external air, and charging the battery by generating electricity when the exhaust gas flows at an internal side of the exhaust pipe. According to the present invention, hybrid electric vehicle can improve a charging rate of the battery by charging the battery through a regenerative braking mode in case of low speed driving and charging the battery with exhaust heat in case of high speed driving, prevent back pressure from being generated by interrupting the flow of the exhaust gas, and constantly maintain a generation rate to provide excellent stability even though a flow rate and a temperature of the exhaust gas are changed.

    본 발명에 의한 하이브리드 전기자동차는, 구동휠을 구동시키기 위한 주행부; 저속 주행 시 상기 주행부에 구동력을 공급하는 모터; 고속 주행 시 상기 주행부에 구동력을 공급하는 엔진; 상기 모터에 전류를 공급하는 배터리; 상기 엔진에서 발생된 동력을 이용하여 상기 배터리를 충전시키는 발전기; 상기 모터와 엔진과 발전기의 동작을 제어하는 제어부; 상기 엔진에서 발생된 배기가스를 외부로 배출시키는 배기관; 및 상기 배기관 내측을 흐르는 배기가스의 열을 전달받는 가열부와, 외기에 의해 냉각되는 냉각부를 구비하여, 상기 배기관 내측으로 배기가스가 흐를 때 전기를 발생시켜 상기 배터리를 충전시키는 열전소자;를 포함하여 구성된다. 본 발명에 의한 하이브리드 전기자동차는, 저속 주행시에는 회생제동 모드를 통해 배터리를 충전시키고 고속 주행시에는 배기열을 이용하여 배터리를 충전시킴으로써 배터리 충전율을 높일 수 있고, 배기가스의 유동에 저해를 주지 아니하여 배압 발생이 방지되며, 배기가스 유량 및 온도가 변경되더라도 발전율을 일정하게 유지시킬 수 있어 안정성이 우수하다는 장점이 있다.
