The invention relates to the technical field of vehicle heat management, in particular to an electric vehicle cooling liquid distribution system. The electric vehicle cooling liquid distribution system comprises a multi-way valve and a heat exchange pipeline system. The multi-way valve comprises four runners which are not crossed with one another; a plurality of interfaces are formed in the periphery of the multi-way valve; every two interfaces are communicated through the runners; the heat exchange pipeline system comprises a battery heat exchange pipeline, a water cooling device pipeline, a heat exchange device pipeline and a power system heat exchange pipeline; two ends of the battery heat exchange pipeline, two ends of the water cooling device pipeline, two ends of the heat exchange device pipeline and two ends of the power system heat exchange pipeline are respectively connected with different interfaces; and the multi-way valve rotates to switch the communicated interfaces so as to switch the pipeline communication mode in the heat exchange pipeline system. According to the cooling liquid distribution system of the electric vehicle, the problems that an overall pipeline switching device is large in size, inconvenient to use, complex in operation and high in air leakage risk in the prior art can be solved.
