The invention discloses a power assembly system and an electric automobile. The structure size of the power assembly system is reduced. The power assembly system comprises two subsystems, the two subsystems are arranged side by side in the first direction and are symmetrical to each other, each subsystem comprises a motor, a speed reducing mechanism and an output shaft, a rotating shaft of each motor is arranged in the second direction, each speed reducing mechanism comprises a cylindrical gear pair and a bevel gear pair, each cylindrical gear pair comprises a driving cylindrical gear and a driven cylindrical gear, and the bevel gear pair comprises a bevel gear. The driving cylindrical gear is connected with a rotating shaft of the motor; the driven cylindrical gear is located on the side, away from the other subsystem, of the driving cylindrical gear. The bevel gear pair comprises a driving bevel gear and a driven bevel gear, the driving bevel gear is located on the side, close to the motor, of the driven cylindrical gear, the small end of the driving bevel gear is arranged close to the motor, and the driving bevel gear is connected with the driven cylindrical gear; the driven bevel gear is located on the side, away from the other subsystem, of the motor and is in transmission connection with the output shaft.
