Comparison of characteristics of main types of new energy vehicles in China.

Type	Hybrid electric vehicle	Blade electric vehicles	Fuel cell vehicle
Driving mode	Internal combustion engine + motor drive	Motor drive	Motor drive
Energy system	Battery, internal combustion engine power generation unit	Battery	Fuel cell
Use energy	Fuel, electric energy	Electric energy	Hydrogen, formaldehyde or gasoline, etc.
Infrastructure	Gas station, grid charging facility (optional)	Grid charging facilities	Storage and loading equipment of fuel cell raw materials
Main features	The emission is very low, the energy conversion efficiency is related to the mixing degree and mixing mode, the driving range is long, the vehicle function is not limited, and part of it depends on crude oil, so the structure is complex	Zero emission, high energy conversion efficiency, short driving range, limited vehicle function, independent of crude oil, relatively simple structure	Zero emission or ultralow emission, high energy conversion efficiency, long driving range, unlimited vehicle functions, can not rely on crude oil, poor adaptation to the working environment
Key points of technological development	Multi-energy management, optimal control	Storage battery and its management, charging facilities	Fuel cell life and cost, hydrogen storage, hydrogenation facilities
