The research team introduces the principle of electric drive system and its main classification, explains the advantages and disadvantages of various electric drive system types, analyzes the main product types of domestic and foreign electric drive systems related to them, discusses the performance characteristics and application models of each product, and discusses the electric drive system solutions for related new energy commercial vehicles and the future development trend, aiming to provide reference for technical research in this field. Commercial vehicles such as buses, trucks and semi-tractors play an important role in daily production. They can be seen everywhere in daily life, such as transportation of goods, transfer of people, strategic resources and express logistics transportation, and spring transportation. In recent years, with the shift of national strategic policies and the emphasis on the living environment, the field of new energy vehicles has been changing rapidly. The subsidies, encouragement and support for new energy vehicles have led major automobile manufacturers to enter this field. New energy vehicles have the advantages of high efficiency, zero emission, environmental friendliness and control state without external influence, and their possession is increasing. New energy commercial vehicles also came into being in this process. The main difference between new energy vehicles and traditional modern vehicles is that the driving method 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 whole new energy vehicle, which directly affects its economy, safety, reliability and other performance.
1. Introduction of electric drive system
The structure of a new energy vehicle is mainly composed of the electric drive system, the chassis, the body frame and various related auxiliary devices. Except for the electric drive system, the functions and structural components of the rest of the vehicle are generally similar to those of a conventional vehicle, but some components have been simplified or replaced due to differences in the selected drive mode. The composition of the electric drive system can be divided into three major parts: auxiliary module, on-board power module, and main electric drive module.
2. The arrangement classification of electric drive system and its characteristics
(1) The central electric drive assembly integrates the drive motor and transmission together, replacing the traditional engine and transmission, but still requires the driveshaft and the traditional axle. It is similar to the traditional vehicle powertrain in terms of arrangement form. And the drive line is long, energy loss is large, system efficiency is low; the bottom space is occupied by a lot, resulting in power battery arrangement difficulties . For example, ZF AG's CeTrax central electric drive assembly system solution is suitable for low and high level buses. Based on a "plug-and-drive" design approach, CeTrax can be integrated into current vehicle platforms without major changes to the chassis, front and rear axles or differentials. The maximum output and peak torque are 300 kW and 4,400 N-m respectively, and the electric drive products of Shaanxi Faster Automotive Transmission Group Co.
