● Realize the platform, lightweight, compact design concept, to meet the requirements of a variety of new energy vehicle space adaptation;

● Combined with the operating conditions of the vehicle, complete the coupling between the engine assembly and the high-efficiency and low-fuel consumption zone of the extended range motor system, improve the efficiency of the extended range system and realize industrialization.

Unique advantages

● Study endurance test method of range extender to realize engineering application and improve product reliability :

● Based on the platform design concept,the whole machine has realized multiple layout forms,which meets the requirements of various vehicle space,among them ,it is the first case that the inclined model carries new energy vehicle in China.

● The connection between the crankshaft end of the special engine for extender and the split-type extended range motor assembly is realized, which significantly reduces the axial size of the whole machine and achieves compact and lightweight.

● Research and develop the sealing structure of the joint surface of the engine and generator for dedicated to the range extender,which makes the high voltage system of the range extender reaches the IP67 protection level.

● The range extender test bench was developed,and the reliability and durability test methods were formulated and applied in engineering.

Application

Passenger vehicles ,commercial vehicles,green logistics vehicles and so on.

Prospect

According to the automobile industry investment managment regulations issued by the National Development and Reform Commission,range-extended electric vehicle investment projects,so as to promote the development of new energy vehicles in China has been transformed from government-driven to market-driven,and most automobile enterprises have carried out the development of range-extended models,indicating a huge market potential for range-extended power.
