The invention relates to a simplified pure electric vehicle thermal management system and method with waste heat recovery, and the system comprises a built-in refrigerant circulation structure which comprises an air blower, a high-voltage PTC electric heater, and a compressor, an evaporator and an inner condenser which are disposed on a refrigerant circulation pipeline. The external heat exchanger is connected to the refrigerant circulating pipeline in parallel through a heat exchange pipeline; the water path circulating structure is connected in series between the built-in refrigerant circulating structure and the external heat exchanger, is connected in series with water path circulating pipes of the motor and the battery, and is used for recovering waste heat so as to realize cooling and heat dissipation of the motor and the battery. Waste heat of the battery and the electrodes is recycled through the water path circulation structure, high-efficiency heat exchange can be achieved under refrigeration and multiple heating modes of the built-in refrigerant circulation structure, and the application prospect is high.
