Abstract: A powertrain includes a reservoir configured to store coolant; a first drive motor, where the first drive motor includes a first stator and a first rotor; a second drive motor, where the second drive motor includes a second stator and a second rotor; a first pump and a second pump, where an inlet of the first pump is coupled to the reservoir, and an inlet of the second pump is coupled to the reservoir; a heat exchanger, where the heat exchanger is coupled to the first pump; a first flow path, where the first flow path is coupled to an outlet of the first pump, and the first flow path is used to supply the coolant to the first stator and the second stator through the heat exchanger.
