A powertrain includes a motor, a reducer, an oil pan, and a cooling system. The cooling system includes at least one heat exchanger and at least two oil pumps. The at least two oil pumps are configured to deliver, to the heat exchanger, cooling oil sucked from the oil pan. The heat exchanger is configured to cool the cooling oil sucked by the at least two oil pumps. An oil outlet port of the heat exchanger is connected to an oil passage in the motor and an oil passage in the reducer, so that a part of the cooling oil cools the motor through the oil passage in the motor, and another part of the cooling oil cools the reducer through the oil passage in the reducer. The embodiments can improve a cooling effect of the cooling system for the powertrain.
