The invention belongs to the technical field of electric vehicles, and particularly relates to a motor waste heat utilization system for an electric vehicle. The motor waste heat utilization system comprises an air inlet module and an air outlet module. The air inlet module comprises a first ring, the first ring is of a cavity structure, and two or more first pipes are arranged on the side wall ofthe first ring at equal intervals in the circumferential direction of the first ring. The first pipes communicate with an inner cavity of the first ring, an annular first groove is formed in the outer circle of the first ring, a through hole is formed in the bottom face of the first groove and leads to the inner cavity of the first ring, a second ring is rotationally installed in the first groove, a gap is formed between the second ring and the bottom face of the first groove, and an air inlet pipe is arranged on the outer circle of the second ring. Hot air in the inner cavity of the motor ispumped out to preheat and preserve heat of a battery, so that the battery is in a normal working environment, and the battery life is prolonged; and meanwhile, important parts of a user can be kept warm, and the user is prevented from catching a cold in cold weather.
