Abstract: An electric drive train for a pure electrically operated vehicle includes an electric motor with a motor shaft and a start-up support unit mechanically connected to the motor shaft configured to convert a motor speed and a motor torque of the motor shaft into an output speed and an output torque such that the output speed is lower than the motor speed and/or the output torque is higher than the motor torque. Also, a method of operating an electric drive train during a start-up process includes increasing a start-up motor speed and a start-up motor torque of a motor shaft of an electric motor, converting the start-up motor speed and the start-up motor torque into a start-up output speed and a start-up output torque with a start-up support unit, and closing a lock-up clutch of the start-up support unit.
