What Are Some Tips About New Energy Vehicles?

[CamilaFitz]

New energy vehicles refer to automobiles that utilize new power systems and rely entirely or primarily on new energy sources for propulsion, mainly including pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles. Types of New Energy Vehicles: New energy vehicles mainly include hybrid electric vehicles, compressed natural gas and liquefied natural gas vehicles, coal-driven vehicles, and biomass energy-driven vehicles. Currently, the main models in mass production are pure electric vehicles, plug-in hybrid electric vehicles, and non-plug-in hybrid electric vehicles. Principles of New Energy Vehicles: Generally, traditional vehicles rely on internal combustion engines to convert the chemical energy of gasoline or diesel into kinetic energy. However, the thermal efficiency of internal combustion engines, i.e., automobile engines, is only 0.2-0.4. When combined with processes such as crude oil extraction, refining, and processing, the average energy utilization rate of crude oil is only about 0.14. If the electrical energy converted from new energy sources is utilized, pure electric vehicles can save up to 70% more energy than fuel vehicles, and costs can also be reduced by about 0.5.
