The invention discloses a cooling circulation system for electric vehicles, and an electric vehicle with the cooling circulation system. The cooling circulation system of the electric vehicle comprises a driving motor, a power electronic unit, a first cooling branch, a second cooling branch, a third cooling branch, a first branch switching unit and a second branch switching unit. According to the cooling circulation system for electric vehicles, and the electric vehicle with the cooling circulation system, which are disclosed by the embodiment of the invention, the first branch switching unit and the second branch switching unit are arranged in the cooling circulation system, and the switching between the first branch switching unit and the second branch switching unit is controlled, so that the switching of cooling loops under different modes can be realized; only parts in a working state under a corresponding mode need to be cooled, and the cooling of all parts is not needed, so that unnecessary consumption is reduced; besides, a cooling pipeline is shortened, and the cooling flow is increased, so that the working efficiency of the cooling circulation system is improved.
