Abstract

The invention relates to a centralized multi-operating-condition thermal management system of a new energy vehicle. The centralized multi-operating-condition thermal management system comprises a refrigerant circuit and a cooling liquid circuit; the refrigerant circuit comprises a compressor, a condenser connected with the compressor, a passenger compartment refrigerant branch circuit and a power battery pack refrigerant branch circuit, wherein the passenger compartment refrigerant branch circuit and the power battery pack branch circuit are connected to the two ends of the compressor and the condenser in parallel; the passenger compartment refrigerant branch circuit comprises an electromagnetic valve and an evaporator for heating a passenger compartment; the power battery pack branch circuit comprises an electromagnetic valve and a heat exchanger for lowering the temperature of cooling liquid; the cooling liquid circuit comprises a PTC heater, a passenger compartment cooling liquid branch circuit and a power battery pack cooling liquid branch circuit, wherein the passenger compartment cooling liquid branch circuit and the power battery pack cooling liquid branch circuit are connected to the two ends of the PTC heater in parallel; the passenger compartment cooling liquid branch circuit comprises a pump and a heater for heating the passenger compartment; the power battery pack cooling liquid branch circuit comprises an electromagnetic valve, a pump, a heat exchanger, a power battery pack, a reflux valve and a one-way valve. According to the centralized multi-operating-condition thermal management system of the new energy vehicle, one set of refrigerating/heating elements can be used for conducting independent thermal management on the passenger compartment and the power battery pack of the new energy vehicle.
