Broadly speaking, a hybrid vehicle (Hybrid Vehicle) refers to a vehicle whose drive system is composed of two or more single drive systems that can operate at the same time. The driving power of the vehicle is based on the actual driving state of the vehicle. Provide together.
Generally speaking, hybrid vehicles generally refer to hybrid electric vehicles (Hybrid Electric Vehicles, HEV), which use traditional internal combustion engines (diesel or gasoline engines) and electric motors as power sources, and some engines have been modified to use other alternative fuels. Such as compressed natural gas, propane and ethanol fuels.
As the environmental protection measures of countries around the world become more and more stringent, hybrid vehicles have become a focus of automotive research and development due to their energy-saving and low-emission characteristics, and they have begun to be commercialized.
The electric power system used in hybrid vehicles includes highly efficient and enhanced electric motors, generators and batteries. Lead-acid batteries, nickel-manganese-hydrogen batteries, and lithium batteries are used for storage batteries. In the future, hydrogen fuel cells should also be used.
