Title:
ELECTRIC MOTOR SYSTEM OF ELECTRIC VEHICLE, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/089107
Kind Code:
A1
Abstract:
The present disclosure provides an electric motor system of an electric vehicle, and an electric vehicle, relating to the technical field of electric vehicles. The electric motor system comprises a housing, a first electric motor, and a first three-phase copper bar. The first electric motor and the first three-phase copper bar are located in the housing, and an end of the first three-phase copper bar is electrically connected to a three-phase line of the first electric motor. The first three-phase copper bar is low cost, has a simple structure and a small volume, can be easily fixed, and requires less layout space in a front compartment of the vehicle, thereby avoiding the problem in which three-phase high-voltage wiring harnesses are used to connect two electric motors to an electric motor controller, and thus result in high costs, a large occupied space, and high layout space requirements for a front compartment of a vehicle.
