The invention provides an oil cooling power assembly and an electric vehicle, the oil cooling power assembly comprises a speed reducer, a motor and an oil pipe, the speed reducer comprises a speed reducer input shaft, the motor comprises a motor shaft, the speed reducer input shaft is fixedly connected with the motor shaft, and the motor shaft is used for transmitting power to the speed reducer input shaft. The speed reducer input shaft comprises a speed reducer shaft cavity, the speed reducer shaft cavity is used for containing the oil pipe and part of the motor shaft, the oil pipe and the speed reducer input shaft are relatively fixed, the motor shaft comprises a motor shaft cavity, and the oil pipe is used for conveying cooling oil to the motor shaft cavity. In the axial direction of the motor, the reducer shaft cavity penetrates through the reducer input shaft, and the motor shaft cavity penetrates through the motor shaft. The oil pipe and the motor shaft are arranged in the axial direction of the motor, and the oil pipe is communicated with the motor shaft cavity. The oil passing pipe is arranged in the shaft cavity of the speed reducer, cooling oil is conveyed to the motor from the speed reducer, the coverage range of the cooling oil in the oil cooling power assembly is enlarged, and the cooling efficiency can be improved.
