The invention relates to a highly integrated motor shell, an electric drive assembly and an electric vehicle, and belongs to the technical field of electric vehicles. The motor shell comprises: a water-cooled motor casing body which comprises a motor casing body and a casing rear end cover, wherein the motor casing body is of a hollow tubular structure, and the casing rear end cover is positionedat one end of the motor casing body and is integrally cast with the motor casing body to form a structure; a controller shell which is connected to the outer wall of the motor shell body, wherein thecontroller shell and the motor shell body are of an integrally cast structure, and the controller shell is of a hollow structure with one end open and the periphery closed; and a cooling channel whichcomprises a cooling water channel and a cooling chamber, wherein the cooling water channel is located in the motor shell body, and the cooling chamber is located in the controller shell body. The electric drive assembly is integrated with a motor shell, a motor and a reduction gearbox, and the electric vehicle is integrated with the electric drive assembly. The device is compact in structure andhigh in reliability. The cooling water channel of the cooling channel is communicated with the cooling cavity in the motor shell, so that the heat dissipation performance is good.
