[0002] With the development of technology, countries have begun to focus on environmental protection and promote green and environmentally friendly transportation. Analysis of the current state of fuel economy in Chinese automobiles, compared with the CO2 emission standards of Japan and the EU, and the US CAFC standard, reveals a significant gap. Electric vehicles have not yet been industrialized globally. However, due to my country's gradual and intensive research and development of electric vehicles, Chinese electric vehicle technology has secured a place in the global automotive market. This is also key to improving the core competitiveness of the Chinese automotive industry.
