POWERTRAIN ARRANGED ALONG POWER FLOW, AND ELECTRIC VEHICLE

A powertrain including an integrated housing, a motor, and a motor controller. The integrated housing includes a motor accommodating cavity, a controller accommodating cavity, a direct-current input interface mounting hole, and an alternating-current output interface mounting hole. The motor includes a motor shaft and a motor winding. The alternating-current output interface mounting hole and a wiring terminal of a winding of the motor are arranged on one side along a first direction. The direct-current input interface mounting hole and an output end of a shaft of the motor are arranged on the other side along the first direction. A projection of the direct-current input interface mounting hole, a projection of the alternating-current output interface mounting hole, and a projection of the motor shaft do not overlap along a third direction. The powertrain in this application has a compact layout to implement miniaturization.
