The invention provides an electrically driven rear axle assembly for an electric vehicle. The electrically driven rear axle assembly for the electric vehicle comprises a rear axle sub assembly and a secondary cylindrical gear transmission; a differential mechanism of the rear axle sub assembly does not contain a differential mechanism driving bevel gear and a driven bevel gear; an outer shell in the differential mechanism is fixedly connected with a driven cylindrical gear; an output gear of the secondary cylindrical gear transmission is directly meshed with the driven cylindrical gear; the secondary cylindrical gear transmission is driven by virtue of a first driving motor and a second auxiliary motor, and a hub of the rear axle sub assembly is fixedly connected with a wheel-side reducer. The electrically driven rear axle assembly for the electric vehicle has the advantages that the structure of the differential mechanism is optimized, and power is output to the differential mechanism in a cylindrical gear drive manner, so that transmission efficiency is improved; large transmission ratio output is realized, and total transmission ratio can be more than 22; two motors are arranged, large torque output is realized without increasing motor power, and transmission efficiency is improved; and the first driving motor and the second auxiliary motor can work simultaneously and also can work alone.
