The invention discloses an electric vehicle transmission. The electric vehicle transmission comprises a transmission shell, a driving motor rotor, a driving motor stator, a sun gear II, a driving motor output shaft and a sun gear I; a shaft extension end of the driving motor rotor is fixedly connected with the driving motor output shaft; the sun gear I sleeves the left end of the driving motor output shaft; a first planet row planet gear is mounted on a planet carrier; a wedged brake I is mounted on the inner wall of the transmission shell, and cooperates with a first planet row planet gear ring; and the sun gear II sleeves the right end of the driving motor output shaft. The electric vehicle transmission has two gears, meets the demands of vehicle acceleration, climbing and the like through reasonable matching of speed ratios, and prolongs the driving range; through integral design of a driving motor and a transmission, a control system is simplified, the number of control elements isreduced, the control difficulty is reduced, and the vehicle NVH performance and the sitting comfort are improved; and through the integral design scheme, the axial size of a power assembly is shortened, and the mounting space is saved.
