While reducing weight and optimizing its own structure, it also needs to meet the strength requirements and improve the utilization rate of raw materials. Make it high speed, reduce motor torque; high efficiency, reduce vehicle energy consumption. Larger grade 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 a high load capacity and often experience insufficient power when climbing slopes or when road conditions are poor (mud, pits, etc.). Low power consumption and high reliability.

The cruising range is one of the important performance indicators of new energy vehicles, especially in the operation of new energy-heavy trucks. The amount of remaining mileage and the energy consumption under complex road conditions all put forward higher requirements for reliability. Conduct in-depth load spectrum studies to identify vulnerable components and increase the working life of the overall system.

Strengthen the simulation analysis and test verification capabilities under extreme working conditions. Good driving experience. Use high power and torque density to obtain better acceleration, complex road conditions, uphill, and overtaking performance. Optimize the NVH of the electric drive system itself, so as to improve the NVH quality of the whole vehicle.
