与传统汽车相比,节能与新能源汽车最大的不同在“动力”上:新能源汽车要么动力来源是汽柴油之外的新能源燃料,要么动力装置不再单纯依靠内燃机技术。简单地说,新能源汽车绝大多数是不烧油的车,包括了混合动力汽车、纯电动汽车、燃料电池电动汽车、氢发动机汽车等几大类。目前,全球能源和环境系统面临着不断加剧的巨大挑战,汽车作为石油消耗和有害气体排放的大户,亟须革命性变革,因而发展能够节能减排的新能源汽车成为广泛共识。近些年来,世界各国都在大力发展新能 Compared with traditional cars, the biggest difference between energy-saving and new energy vehicles is on the “power”: the new energy vehicles are either powered by new energy sources other than gasoline and diesel, or the powerplant no longer relies solely on internal combustion engine technology. Simply put, the vast majority of new energy vehicles are not burning oil vehicles, including hybrid vehicles, pure electric vehicles, fuel cell electric vehicles, hydrogen engine cars and other categories. At present, the global energy and environment system is facing a tremendous challenge. As a major player in oil consumption and harmful gas emissions, the automobile industry is in urgent need of revolutionary change. As a result, it is widely agreed that the development of new energy vehicles that can save energy and reduce emissions should be achieved. In recent years, all countries in the world are vigorously developing new energy
