A hybrid electric vehicle according to the present invention includes: a driving unit for driving a driving wheel; a motor configured to supply a driving force to the driving unit during low-speed driving; an engine configured to supply a driving force to the driving unit during high-speed driving; a battery configured to supply a current to the motor; a generator configured to charge the battery by using power generated by the engine; a control unit configured to control the motor, the engine, and the generator; an exhaust pipe configured to discharge exhaust gas generated by the engine to the outside; a cooling jacket mounted on the engine; a radiator configured to receive cooling water extracted from the cooling jacket through a cooling water extraction pipe and returning the cooling water to the cooling jacket through a cooling water supply pipe after cooling the cooling water; and a thermoelectric element including a heating part configured to receive heat of the exhaust gas flowing through the inside of the exhaust pipe and a cooling part cooled by the cooling water flowing through the inside of the cooling water supply pipe, and charging the battery by generating electricity when the exhaust gas flows through the inside of the battery and the cooling water flows through the cooling water supply pipe. Accordingly, the battery is charged through a regenerative breaking mode during low-speed driving and can be charged by using heat of the exhaust gas during high-speed driving.
