What are the energy sources for new energy vehicles?

[MilaAnn]

New energy vehicles utilize various energy sources including fuel cells, hydrogen energy, solar power, and alcohol ethers. New energy vehicles refer to automobiles that employ unconventional vehicle fuels as their power source (or use conventional vehicle fuels but incorporate new onboard power devices), integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and innovative structures. New energy vehicles encompass four main types: Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEV, including solar-powered vehicles), Fuel Cell Electric Vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). The promotion of new energy vehicles aims to address environmental protection and petroleum crisis concerns by reducing or abandoning the current mainstream models that rely on burning traditional gasoline or diesel to power internal combustion engines.
