Similar to traditional automobiles, many of the core technologies of new energy vehicles are actually in the hands of key component suppliers. Taking the battery as an example, each auto company has one alliance with battery manufacturers. One of its goals is to hope that these new core suppliers can participate from the product development stage, in order to promote breakthroughs in key battery technologies and provide more Automotive demand for battery components.

Therefore, in addition to the investment in vehicle development and market subsidies, the government of many countries also pays close attention to the core components of new energy vehicles. This is also the core competitiveness of the new industry. The relevant support policies are also introduced. In reasonable terms. Taking Europe, the United States, and Japan as the three major global automobile production and consumption regions as examples, the relevant policies of various governments are worth studying.

In October 2008, the European Parliament passed a proposal in Strasbourg, France, to encourage the development of cleaner cars. The bill requires the public sector and companies engaged in public passenger transport services to use the energy consumption of cars and carbon dioxide when purchasing vehicles in the future. And other pollutant emission indicators were included in the screening scope.

In March 2009, the European Investment Bank (EIB), an EU-affiliated financing agency, announced that it will release a €7 billion loan to automakers in the first half of the year for the development and promotion of environmentally friendly vehicles. In the second half of the year, the agency may add a loan for this project.

In January 2009, the German government passed a 50 billion euro economic stimulus plan, a large part of which was used for research and development of electric vehicles, network construction of car charging stations and renewable energy development. The German government recently stated that by 2020, the number of new energy vehicles in Germany will exceed 1 million.

In October 2008, French President Nicolas Sarkozy announced at the Paris International Motor Show that the French government will invest 400 million euros in the development of clean energy vehicles. In addition to investing heavily in research and development, France is also preparing to take complementary measures to ensure the smooth operation of environmentally friendly vehicles such as electric vehicles, such as increasing the number of charging stations in the workplace, supermarkets and residential areas, so that charging is as easy as refueling. The government will give a high subsidy of 5,000 Euros to the purchase of "super green cars" with carbon dioxide emissions below 60 grams per kilometer. This policy will continue until 2012 and will expand to more models.

The British Department of Transportation has announced plans to allocate 250 million pounds (US$373 million) in funds to encourage the promotion of low-emission vehicles such as electric vehicles. Consumers who buy the first pure electric car and plug-in hybrid car will receive a reward of £2,000 to £5,000. It is expected that such vehicles will be available for sale in 2011. The strategy also includes £20 million in funding for charging stations and related infrastructure to promote the formation of a network of “electric car cities”.

The United States In December 2008, the United States announced a new comprehensive energy plan, which will focus on investing 150 billion U.S. dollars in support of clean vehicle technology R&D in the next 10 years. The plan proposes the following goals: By 2015, the number of plug-in hybrid vehicles in the United States will reach 1 million, and these vehicles will have a mileage of 150 miles per gallon and be guaranteed production in the United States.

In March 2009, U.S. President Barack Obama announced that US$2.4 billion will be used to fund U.S. manufacturers and related organizations to produce next-generation plug-in electric vehicles and advanced battery components. Americans buying plug-in hybrids can apply for up to $7,500 in tax benefits. The U.S. Department of Energy will provide US$1.5 billion in U.S. battery manufacturers’ production of high-efficiency batteries and their components; US$500 million in U.S. manufacturers’ production of other parts for electric vehicles, such as motors; and 400 million U.S. dollars for plug-ins Demonstration operation and evaluation of hybrid vehicles and other electrical facilities - such as truck parking station charging stations, electrical tracks, training of electric vehicle assembly and maintenance technicians. The Ministry of Energy will also support the market-oriented promotion of advanced electric vehicles, such as demonstration operations, technology assessment and education projects.

In April 2009, U.S. President Barack Obama said that the federal government will purchase 17,600 energy-saving vehicles, including new energy vehicles, which will be manufactured by the top three automakers in the United States.

In April 2009, the U.S. Department of Energy’s National Laboratory and the Battery Manufacturing Alliance established a research and development and manufacturing center in Kentucky with the goal of providing high performance lithium battery packs for plug-in hybrid vehicles. According to reports, the University of Kentucky has an advantage in automotive engineering technology. At the same time, the state’s automobile production ranks third in the United States, which provides a good basis for the research and development of new energy vehicles.

In 1974, Japan proposed a new energy technology development plan, and later in 1978 and 1989 respectively put forward the "energy-saving technology development plan" and "environmental technology development plan." In 1993, the Japanese government merged the above three plans into a large-scale "New Sunshine Project." The main purpose of the “New Sunshine Project” is to adopt a joint model of the government, the enterprise, and the university under the leadership of the government to work together to overcome various problems encountered in energy development. In order to ensure the smooth implementation of the “New Sunshine Project”, the Japanese government will allocate more than 57 billion yen each year for the plan, of which approximately 36.2 billion yen will be used for research and development of new energy technologies.

In April 2009, Japan began implementing a one-year "green taxation system" to eliminate the vehicle purchase tax for consumers purchasing environmentally-friendly cars. The target of the application is the next-generation automobiles recognized by the Japanese government, including electric vehicles, natural gas vehicles, and clean diesel. Cars and certified low-emission vehicles. At the same time, it is required that government agencies purchase vehicles must all be low-emission vehicles. According to the plan of the Japanese government, there will be 50,000 fuel cell vehicles in Japan in 2010. Japan also announced that it will increase the number of hybrid and fuel cell vehicles from the current 600,000 to 10 million in 2010.

In April 2009, the Japanese government introduced a new large-scale economic stimulus policy, including: investing approximately 370 billion yen, further increasing subsidies for the purchase of environmentally friendly vehicles. This is Japan's policy of encouraging redemption of cars by reference to the major western countries. It is necessary to spread energy-saving and environmentally-friendly cars at the fastest speed in the world. The Japanese government wants to increase the sales of about 1 million environmentally-friendly cars and create 120,000 jobs.
