The invention provides a heat pump heat management system for a new energy automobile and a working method of the heat pump heat management system. The heat pump heat management system comprises a passenger compartment heat management loop and a battery heat management loop. The passenger compartment heat management loop comprises an electric compressor, an indoor condenser, an outdoor heat exchanger and an indoor evaporator which are connected in sequence, and a refrigerant circularly flows through the passenger compartment heat management loop to refrigerate/heat a passenger compartment; the battery thermal management loop comprises a battery cooling liquid circulation loop, and the battery cooling liquid circulation loop comprises a first water tank, a dual-core battery cooler and a battery pack which are connected in sequence; and the output end of the outdoor heat exchanger is also connected with the double-core battery cooler, so that the refrigerant passing through the outdoor heat exchanger flows through the double-core battery cooler and exchanges heat with the cooling liquid flowing through the double-core battery cooler in the battery cooling liquid circulation loop to cool the battery pack. The low-temperature mileage anxiety of the new energy automobile can be solved while the low-temperature heating energy efficiency and the system cost are considered.
