The invention discloses a heat pump type heat management system and method for an electric automobile. The heat pump type heat management system comprises a heat supply ventilation and air conditioning assembly, cooling liquid loops connected to nine different connectors of a multi-way valve and a refrigerant loop capable of conducting heat exchange with the cooling liquid loops. The cooling liquid loop comprises an electric drive loop, a heat dissipation loop, a battery loop, a coupling loop for connecting the electric drive loop and the heat dissipation loop with the multi-way valve, a first heat exchange cooling liquid loop connected with the warm air core body and the first heat exchanger, and a second heat exchange cooling liquid loop connected with the second heat exchanger; the refrigerant loop comprises a first refrigerant series loop for connecting the compressor, the first heat exchanger and the second heat exchanger in series and a second refrigerant loop for connecting the compressor, the first heat exchanger and the evaporator in series; circulating flow of various cooling liquids can be achieved by controlling communication or cut-off of all the connectors, and control and switching of various heat management can be achieved through heat exchange of the cooling liquid loop and the refrigerant loop.
