This application discloses a power assembly and an electric vehicle. The power assembly includes a rotor iron core, a gear set, a rotating shaft, and an oil-pumping system. The rotating shaft is fixedly connected to the rotor iron core and a driving gear in the gear set. The housing has an oil storage pool at a bottom and an oil collection tank at a high location, a part of a structure of a first gear in the gear set is located in the oil storage pool, and the first gear rotates to drive cooling oil in the oil storage pool to be raised and collected by the oil collection tank. The rotating shaft has a cooling oil channel inside. The cooling oil in the oil collection tank flows to the cooling oil channel, to dissipate heat from the rotor iron core. The oil-pumping system includes an oil pump. The oil pump pumps the cooling oil in the oil storage pool into the cooling oil channel. In this solution, two oil paths may be used to dissipate heat from the rotor iron core. This application includes two oil paths for dissipating heat from the rotor iron core, so that cooling requirements of the rotor iron core during high-speed operation and low-speed operation of the power assembly both may be met, to improve a cooling effect of the rotor iron core of the power assembly.
