The invention belongs to the technical field of electromobiles, and discloses a high-reliability electromobile adopting a low-voltage large-torque coaxial motor power system. The power system mainly comprises a main controller and 2 to 6 coaxial motor power units which output power separately or synchronously via one power output spindle; and each motor power unit comprises a permanent magnet brushless DC (direct current) single-body motor sharing the same power output spindle, a corresponding single-body motor driver and a corresponding lithium ion battery pack, wherein the rated power of the single-body motor is between 5 and 25 KW, the rated voltage is between 60 and 150 V DC, and the rated speed is between 500 and 1500 RPM (Revolutions Per Minute). The power system and the electromobile adopting the system provided by the invention have the advantages of good reliability and safety.
