Abstract
A powertrain for an electric vehicle includes: a planetary gear including a first rotating element, a second rotating element, and a third rotating element, where the first rotating element is connected to a first shaft, the second rotating element is connected to a second shaft, and the third rotating element is connected to a third shaft; a first motor selectively supplying power to the first shaft at two or more gear ratios; and a second motor selectively supplying power to the first shaft and the second shaft. The third shaft is fixedly disposed on a transmission housing, and any two shafts among the first, second and third shafts restrain each other.
