ybrid electric vehicle refers to combining the internal combustion engine with electric motor hybrid car.
Today the development of cleaner cars is the world automotive trends. Fuel Cell Vehicles are defined by their hydrogen fuel cell-powered energy to drive motor so as to direct-drive electric vehicles. Hybrid electric vehicle refers to combining the internal combustion engine with electric motor hybrid car.
We researched and developed prototyping of electric motor of HEV, whose parameters are in the following table:
Peak torque | 120Nm |
Max current | 240A |
Continuous torque | 42Nm |
Continuous power | 21kW |
Peak efficiency | 93% |
Peak electric power | 60kW |
Power | 300VDC |
Speed | 0~4580 r/min~10000 r/min |
Weight | 70kg |
Diameter | 250mm |
Length | 370mm |
This year, we signed with the institute of electrical engineering of Chinese Academy of Sciences for jointly developing hybrid electric vehicle motor drive system and industrial production research. We has manufactured HEV motor drive system for public buses.
We also cooperate with Shanghai University for develop this technology. Which has following data:
