The trend of new energy heavy-duty trucks

With the development and research of new energy heavy-duty trucks in the industry, considering the main factors of economy, integration, safety, and lightweight, high-speed, high efficiency, high reliability, and good NVH of the electric drive system, the trend of new energy heavy-duty trucks mainly has the following aspects.

1) Low production cost and low maintenance cost. During the daily use of new energy heavy-duty trucks, charging piles, vehicle maintenance, and battery life all require certain financial investment. In order to meet the economic requirements, pursuing lower costs and maintenance costs is one of the main goals of promoting new energy vehicles.

2) Lightweight body and modular electric control system. The greater the vehicle’s own weight, the higher the battery energy consumption during operation. The electric drive system needs to control more complex and more parts, and modularization is a way to divide a complex system into better manageable modules. In addition to lightweight and optimizing the structure, it is also necessary to meet the strength requirements and improve the utilization rate of raw materials. This makes the system run at high speed, reduce the motor torque; improve efficiency, reduce the overall energy consumption.

3) Greater climbing ability and stronger power performance. The power provided by the electric drive system is limited by factors such as motor power and battery size. Heavy-duty trucks have a heavy weight and high load, and often have insufficient power when climbing hills or encountering poor road conditions (muddy, potholes, etc.).

4) Low energy consumption and high reliability. Range is one of the important performance indicators of new energy vehicles, and it is even more important in the operation of new energy heavy-duty trucks. The remaining mileage, energy consumption in complex road conditions, all put higher demands on reliability. Conduct in-depth load spectrum research to identify vulnerable components, increase the service life of the entire system. Strengthen the simulation analysis and experimental verification capabilities in extreme working conditions.

5) Good driving experience. Achieve better acceleration, complex road conditions, uphill, and overtaking performance with high power and torque density. Optimize the NVH of the electric drive system itself to improve
