The present invention relates to a hybrid electric vehicle capable of charging a battery using engine heat during high-speed driving. The hybrid electric vehicle according to the present invention includes: a driving unit for driving a driving wheel; a motor for supplying a driving force to the driving unit when driving at a low speed; an engine for supplying a driving force to the driving unit when driving at a high speed; a battery for supplying current to the motor; a generator for charging the battery using power generated by the engine; a controller for controlling the motor, the engine, and the generator; a cooling jacket mounted on the engine; a radiator for receiving cooling water drawn from the cooling jacket through a cooling water drawing tube and cooling the cooling water, and then returning the cooling water to the cooling jacket through a cooling water supply tube; and a thermoelectric element including a heating unit for receiving high temperature cooling water flowing through the inside of the cooling water drawing tube and a cooling unit which is cooled by external air, in which the thermoelectric element generates electricity when the high temperature cooling water flows into the cooling water drawing tube to charge the battery.
