Abstract: This application provides a control apparatus for a power system of an electric vehicle and a related device thereof. The control apparatus obtains a driving mode of the electric vehicle, a running parameter of the electric vehicle, and a running parameter of the power system, and in response to an accelerator signal or a brake signal of the electric vehicle, outputs a torque allocation ratio of a front drive motor to a rear drive motor based on the driving mode of the electric vehicle, the running parameter of the electric vehicle, and the running parameter of the power system. During implementation of this application, the motor is flexibly controlled by considering impact of a plurality of factors, to achieve good reliability.

Abstract: A powertrain and a vehicle. The powertrain includes an enclosure, a separator, a motor, a first liquid return channel, and a second liquid return channel. The separator separates an interior of the enclosure into a first cavity and a second cavity. The motor is located in the first cavity. The first liquid return channel is located on an outer side of the enclosure and communicates with the first cavity and the second cavity. The second liquid return channel is located on the outer side of the enclosure and communicates with the first cavity and the second cavity. In the embodiments, with two liquid return channels provided, a liquid return requirement can be met when the powertrain is installed or disposed at any angle or used on a slope, improving adaptability and safety of the powertrain.
