An intelligent multiple-loop electric vehicle cooling system includes a battery pack, an electric drive module, a battery radiator, an electric drive module radiator, electric pumps, pass-through valves, three-way valves, a PTC heater, a heat exchanger. The cooling system is provided with two electric pumps, two pass-through valves, and three three-way valves that are connected through pipelines to form multiple loops. Compared with the prior art, by means of the present invention, multiple three-way valves and pass-through valves are disposed, to connect pipelines to form loops meeting different cooling or heating requirements. These loops are selectively opened or closed according to features and working states of a battery pack and an electric drive module of an electric vehicle, to ensure temperature balance of the electric vehicle and efficient operation of the electric vehicle.
