The invention discloses a power train for an electric vehicle. The power train may include a planetary gear set including three rotation elements having a first rotation element, a second rotation element and a third rotation element, wherein the first rotation element is connected to a first shaft, the second rotation element is connected to a second shaft, and the third rotation element is connected to a third shaft; a first motor mounted to selectively supply power to the first shaft in two or more gear ratios; and a second motor mounted to selectively supply power to the first shaft in two or more gear ratios. The third shaft is configured to be fixed to a transmission housing, and any two of the first shaft, the second shaft, and the third shaft are configured to be coupled to each other.
