New energy vehicles have the advantages of high efficiency, zero emissions, environmental friendliness, and the control state will not be affected by the outside world, and their share is increasing. New energy commercial vehicles also emerged in this process. The main difference between new energy vehicles and traditional modern vehicles is that the drive mode of new energy vehicles has been changed to electric drive. The electric drive system is mainly divided into four parts: drive motor, transmission, power converter, and controller. The electric drive system is the core of the entire new energy vehicle, which directly affects its economy, safety, reliability and other performances.
Introduction to electric drive system The structure of new energy vehicles is mainly composed of electric drive system, chassis part, body frame and various related auxiliary devices. Except for the part of the electric drive system, the functions and structural composition of the other parts are generally similar to those of traditional cars, but some parts are simplified, modified or replaced due to different driving methods. The composition of the electric drive system can be divided into three parts: auxiliary module, vehicle power supply module, and electric drive main module.
