Electric drive system and vehicle

Abstract

To improve the cooling efficiency of an electric drive system.SOLUTION: In an electric drive system, an electric motor includes a housing with a stator and a rotor, and the housing includes a first electrical connector located at an outlet terminal of the stator and electrically connected to a controller, and a second electrical connector located at the outlet terminal of the stator and electrically connected to the stator. A cooling system of an electric motor includes a cooling channel located in the housing and a coolant distribution assembly connected to the cooling channel, the coolant distribution assembly includes at least one first hole provided therein such that a coolant flows through the at least one first hole toward the first electrical connector, and the coolant distribution assembly further includes at least one second hole provided therein such that coolant flows through the at least one second hole toward the second electrical connector.SELECTED DRAWING: Figure 3
