5. A powertrain for an electric vehicle, the powertrain comprising:
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 configured to supply power to the first shaft at all times; and
a second motor configured to selectively supply power to the first shaft and the second shaft,
wherein the third shaft is fixedly connected to a transmission housing, and
two shafts among the first, second, and third shafts are configured to restrain each other,
wherein a first shift assembly is provided between the second motor and the first shaft and configured to switch between a state in which power of the second motor is directly transmitted to the first shaft and a state in which the power of the second motor is transmitted to the second shaft by shifting of a gear train.
