The invention belongs to the technical field of automobile heat management, and relates to an electric automobile integrated heat management system and a control method thereof.The heat management system comprises a refrigerant loop and a cooling liquid loop, and the refrigerant loop comprises a first refrigerant loop, a second refrigerant loop, a third refrigerant loop and a fourth refrigerant loop; the cooling liquid loop comprises a first cooling liquid loop, a second cooling liquid loop and a third cooling liquid loop. Through correlation coupling of the refrigerant loop and the cooling liquid loop, waste heat of equipment such as a motor is fully utilized, different function scenes of independent or correlation operation of passenger compartment heat management, battery heat management and motor heat management can be achieved, the cooling and heating function requirements of the heat management system are met, the function application scenes are comprehensive, and the application range is wide. The problem that the balance among the driving range, comfort and safety of the electric vehicle in the actual environment cannot be well achieved due to the fact that the existing whole vehicle thermal management function scenes are relatively few is solved.
