Claim 8:
9. A powertrain for an electric vehicle, the powertrain comprising:
a planetary gear having a first rotating element, a second rotating element, and a third rotating element, wherein the first rotating element is connected to a first shaft and the second rotating element is connected to a second shaft;
a first motor configured to selectively supply power to the first shaft at two or more gear ratios;
a first shift assembly configured to transfer power of the first motor to the first shaft through one of two or more external engagement gear trains having different gear ratios; and
a second motor configured to selectively supply power to the first shaft and the second shaft,
wherein:
a seventh gear is connected to the first shaft such that rotation of the seventh gear is restrained;
an eighth gear is connected to the second shaft such that rotation of the eighth gear is restrained;
a ninth gear in external engagement with the seventh gear and a tenth gear in external engagement with the eighth gear are disposed coaxially with each other; and
the second motor is disposed to be connectable to the first shaft and the second shaft via a second shift assembly disposed between the ninth gear and the tenth gear.
