The invention discloses a dual-motor power device for an electric vehicle. The dual-motor power device comprises a controller, a main driving motor, an auxiliary motor, a planet gear train and a clutch. A rotating shaft of the main driving motor is connected with a sun wheel of the planet gear train, and a planet frame of the planet gear train serves as a power output end; a driving portion of the clutch is connected with a gear ring of the planet gear train, and a driven portion of the clutch is connected with the sun wheel of the planet gear train; and a rotating shaft of the auxiliary motor is connected with the gear ring of the planet gear train, and a brake is used for braking a rotating shaft of the auxiliary motor and the gear ring. The dual-motor power device for the electric vehicle is simple in structure and achieves a torque coupling driving manner and a rotating speed coupling driving manner.
