The invention discloses an electric vehicle power assembly and an electric vehicle, belongs to the technical field of electric vehicles, and aims to solve the technical problem of how to provide an electric vehicle drive which is simple in structure, low in energy consumption and high in gradeability. Comprising a starting motor, a running motor and a power mechanism composed of a gear ring, a brake and a planetary gear mechanism. The transmission mechanism comprises a planetary gear mechanism and a gear ring, the gear ring is in meshing transmission connection with the outer diameters of a plurality of planetary gears in the planetary gear mechanism through the inner diameter of the gear ring, and a planet carrier in the planetary gear mechanism and the gear ring serve as transmission ends of the transmission mechanism. Wherein one transmission end is locked by a brake, and the other transmission end is in transmission connection with an output shaft gear. A motor shaft of the starting motor is in transmission connection with a sun gear in the planetary gear mechanism, and a motor shaft of the operation motor is in meshing transmission connection with an output gear in the output shaft gear through an operation gear.
