Abstract
The present invention relates to a powertrain for an electric vehicle, which can include: an input shaft and an output shaft mounted parallel to each other; a first power transmission mechanism and a second power transmission mechanism provided to transmit power from the input shaft to the output shaft at two different transmission ratios from each other; a one-way clutch included in the first power transmission mechanism; a friction clutch included in the second power transmission mechanism; and a bypass mechanism provided to form a power transmission path bypassing the one-way clutch and a power transmission path bypassing the friction clutch.
