What is a Hybrid Electric Vehicle?

[Pete]

Hybrid Electric Vehicle: 1. Broad definition. Refers to a vehicle whose propulsion system consists of two or more individual drive systems that can operate simultaneously. The vehicle's driving power is provided by either one of the drive systems alone or jointly, depending on the actual driving conditions. 2. Fuel introduction. Generally refers to a Hybrid Electric Vehicle (HEV), which uses a traditional internal combustion engine (diesel or gasoline) and an electric motor as power sources. Some engines are modified to use alternative fuels such as compressed natural gas, propane, and ethanol. Additional information: 1. As environmental protection measures become increasingly stringent worldwide, hybrid vehicles have become a key focus in automotive research and development due to their energy-saving and low-emission characteristics, and they have already entered commercialization. 2. The electric power system used in hybrid vehicles includes highly efficient and enhanced electric motors, generators, and batteries. 3. The batteries used include lead-acid batteries, nickel-metal hydride batteries, and lithium batteries, and in the future, hydrogen fuel cells may also be utilized.
