Abstract

The present disclosure provides a motor system of an electric vehicle and an electric vehicle, belonging to the technical field of electric vehicles. The motor system includes a power assembly, a connection assembly and a motor controller; the connection assembly includes a terminal block, a first three-phase copper busbar, a second three-phase copper busbar, a first three-phase connector, and a second three-phase connector; the terminal block It is connected with the inner wall of the casing of the transmission; one end of the first three-phase copper bar is fixed on the wiring seat, and the other end is connected with the first three-phase connector; one end of the second three-phase copper bar is fixed on the wiring seat, and the other end is connected to the wiring seat. The second three-phase connector is connected; the motor controller is located outside the casing of the transmission and is connected with the first three-phase connector and the second three-phase connector. Copper bars and connectors have low cost, simple structure and small volume, and are easy to fix. They require less space for the layout of the front cabin of the vehicle, avoiding the high cost and occupying a large space caused by the use of three-phase high-voltage wiring harnesses to connect the motor controller and the motor. The problem of high requirements on the layout space of the front cabin of the whole vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of electric vehicles, in particular to a motor system of an electric vehicle and the electric vehicle. Background technique [0002] Electric vehicles are one of the representatives of new energy vehicles, usually including pure electric vehicles and hybrid vehicles. Pure electric vehicles are only driven by electricity, and the power source is only the motor, while hybrid vehicles can be driven by electricity and fuel, and the power sources include motors and engines. [0003] At present, there is an electric vehicle equipped with two motors, both of which are connected to the transmission. Both electric motors are connected to a motor controller located outside the transmission housing. Both motors are three-phase motors, that is, three-phase power supply is used. [0004] The two motors and the motor controller are connected by a three-phase high-voltage wire harness. The three-phase high-volt...
