The present invention discloses a power system of an electric vehicle, capable of installing reducers, axle different reduction gear ratios, in two motors and then connecting the reducers to the same shaft, and improving demand performance by selecting or combining first and second motors according to driving demand torque. The present invention includes first and second motors, comprising a power source; first and second reducers connected to the first and second motors, and having different reduction gear ratios; an operating axle connecting the output of the first and second reducers with the same axle; a vertical motion gear delivering power, delivered through the operating axle, to right and left wheels; and a motor controller controlling the output torque of the first and second motors by determining a driving point corresponding to the first and second motors according to a driving demand and a driving situation. |
