Abstract: A coupling thermal management system of a pure electric vehicle based on phase change heat storage. The system includes a refrigerant circuit and a coolant circuit, where heat exchange can be achieved between the refrigerant circuit and the coolant circuit through a plate type heat exchanger. The refrigerant circuit includes an electric compressor, an inside-vehicle heat exchanger, an outside-vehicle heat exchanger, a bidirectional electronic expansion valve, a four-way directional valve, a gas-liquid separator, first three-way valve, a first gate valve, a second gate valve, a plate type heat exchanger and a refrigerant tube. The coolant circuit includes a battery pack, a phase change material, a heat storage heat exchanger, a water pump, a second three-way valve, a third three-way valve, a fourth three-way valve and a coolant tube. The plate type heat exchanger is also included in the coolant circuit.
