The embodiment of the invention provides a stator winding end immersion cooling driving motor, a power assembly and an electric vehicle. The driving motor comprises a stator core, a stator winding and a cooling cover. The stator core is used for fixing the stator winding. One winding end part of the stator winding in the axial direction of the driving motor is exposed out of one end of the stator iron core, and the inner diameter of one winding end part of the stator winding in the radial direction of the driving motor is larger than that of the stator iron core. The cooling cover is used for accommodating cooling liquid and a winding end part. The cooling cover comprises a first annular wall, and the outer diameter of the first annular wall in the radial direction of the driving motor is smaller than or equal to the inner diameter of one winding end of the stator winding. The end, facing the stator core in the axial direction of the driving motor, of the first annular wall is used for enclosing the end of the stator core to form an accommodating structure. And the cooling liquid accommodated in the accommodating structure is used for immersing and cooling one winding end part of the stator winding. According to the embodiment of the invention, good heat dissipation can be carried out on the stator winding.
