Development trend of new energy heavy truck electric drive system At present, the main configurations of new energy electric drive system are low-speed high-torque single motor or low-speed high-torque dual-motor direct drive type, low-speed motor with AMT gearbox type, high-speed motor with reducer type, etc.
The development trend of new energy heavy trucks With the development and research of new energy heavy trucks in the industry, taking into account the main factors such as economy, integration, and safety, and electric drives with light weight, high speed, high efficiency, high reliability, and good NVH Combined with the future development trend of the system, the development trend of new energy heavy trucks mainly includes the following aspects. Low production cost and low maintenance cost. In the daily use of new energy heavy trucks, a certain amount of capital investment is required for charging piles, vehicle maintenance, and battery life. In order to ensure economical requirements, the pursuit of lower costs and maintenance costs is one of the main goals of promoting new energy vehicles. The weight of the body is reduced, and the electronic control system is modularized. The greater its own mass, the higher the battery energy consumption during work. Electric drive systems need to control more and more complex components, and modularization is a way to decompose complex systems into better manageable modules.
