The invention relates to the technical field of electric vehicle heat management, in particular to an indirect heat pump type heat management system. Comprising an electric drive cooling liquid loop, a battery cooling liquid loop, a heating cooling liquid loop and a refrigerant loop. The heating cooling liquid loop comprises a first heating loop and a second heating loop; the first heating loop is connected in series with a warm air core body; the second heating loop exchanges heat with the battery cooling liquid loop through the battery heating heat exchanger; the refrigerant loop comprises a first refrigerating loop, a second refrigerating loop and a third refrigerating loop; the first refrigerating loop exchanges heat with the heating coolant loop through the water-cooled condenser; the second refrigerating loop exchanges heat with the battery cooling liquid loop through the battery cooling heat exchanger; an evaporator used for cooling the passenger compartment is connected to the third refrigeration loop in series. And the battery cooling liquid loop and the electric drive cooling liquid loop are mutually coupled and communicated. The indirect heat pump type heat management system can well meet the heating requirements of a battery pack and a passenger compartment.
