Abstract: An electric vehicle including the Rankine cycle in which a circulation system of working fluid is formed is proposed. The Rankine cycle includes a pump configured to circulate the working fluid along the circulation system, a heat source comprising a battery unit, a motor unit, and a solar panel unit to transmit thermal energy to the working fluid circulated by the pump, a power generating unit provided on a path of the circulation system to generate electric energy through the thermal energy of the working fluid passing through the heat source, and a radiator configured to perform a heat exchange process between the working fluid passing through the power generating unit and outside air. The Rankine cycle further includes a flow distributor to distribute the working fluid circulated by the pump to at least any one of the battery unit, the motor unit, and the solar panel unit.
