A power transmission apparatus of an electric vehicle includes a motor shaft fixed to a drive motor and receiving the torque of the drive motor, a first input shaft disposed on a same axis with and selectively connectable to the motor shaft, a second input shaft coaxially disposed with the first input shaft, and selectively connectable to the motor shaft, front and rear wheel driving devices for driving front and wheels, a first shifting section for shifting a torque of the first input shaft and selectively transmit the shifted torque to the front wheel driving device, a second shifting section for shifting a torque of the second input shaft and selectively output the shifted torque, and a mode conversion unit of transferring an output torque of the second shifting section to at least one of the front wheel driving device and the rear wheel driving device.
