China’s relevant standards for lithium-ion power batteries
At the Copenhagen Climate Conference, China clearly stated that carbon emissions per unit of GDP will be reduced by 40% to 45% in 2020.
In 2001, the country launched the largest technology project in history and established the “three horizontal and three vertical” (fuel cell vehicle, hybrid electric vehicle, and pure electric vehicle three vehicle technologies are three horizontal, powertrain system, drive motor, and power battery. One of the key technologies is the R&D layout of three verticals.
In 2006, in accordance with the “Outline of the National Medium and Long-term Science and Technology Development Plan” and the “Eleventh Five-Year Development Outline of the National High-Tech Research and Development Plan (863 Program),” combined with the “Tenth Five-Year Plan”, “Electric Vehicle Major Science and Technology Special Project” and the “Tenth Five-Year Plan”. The “Five” Clean Vehicle Action has achieved results, and the Ministry of Science and Technology has set up the “863 Program Energy-saving and New Energy Vehicle Major Special Project”. The key tasks of the regulations are: to promote the research and development and demonstration of fuel cell vehicles, realize the large-scale industrialization of hybrid electric vehicles, expand the application range of pure electric vehicles, and further expand the promotion and application of alternative fuel vehicles; promote energy-saving and new energy vehicle industry policies and regulations Research and formulation of relevant standards, improve relevant testing and evaluation capabilities, form intellectual property protection and investment and financing service systems, build a public service platform for energy-saving and new energy vehicles, and establish China’s energy-saving and new energy vehicle industry alliances; grasp the transformation of transportation energy power systems This is a major opportunity for the establishment of an independent R&D and innovation system that combines production, education and research with enterprises as the main body.
On October 6, 2008, BYD acquired the semiconductor manufacturing company Ningbo Zhongwei, which has the R&D and production capabilities of electric vehicle drive motors. On December 15, 2008, BYD F3DM, as the world’s first dual-mode electric vehicle that does not rely on professional charging stations, was officially launched in Shenzhen.
In January 2009, the Ministry of Finance and the Ministry of Science and Technology jointly issued the “Notice on Carrying out the Pilot Work for Demonstration and Promotion of Energy-saving and New Energy Vehicles”, and decided to launch in Beijing, Shanghai, Chongqing, Changchun, Dalian, Hangzhou, Jinan, Wuhan, Shenzhen, Hefei , Changsha, Kunming, and Nanchang have carried out pilot projects for demonstration and promotion of energy-saving and new energy vehicles, and proposed a “thirteen cities with 1,000 vehicles” plan within three years.
In February 2009, the State Council issued the “Automotive Industry Adjustment and Revitalization Plan”, the policy is towards the development of electric vehicles, and proposed to form a production capacity of 500,000 new energy vehicles by 2011.
In February 2009, the “Interim Measures for the Management of Financial Subsidy Funds for the Demonstration and Promotion of Energy-saving and New Energy Vehicles” was promulgated. Public service passenger vehicles and light commercial vehicles have a minimum subsidy of 4,000 yuan and a maximum subsidy of 50,000 yuan; pure electric passenger vehicles and light commercial vehicles have a subsidy of 60,000 yuan, and fuel cell passenger vehicles and light commercial vehicles have a maximum subsidy of 25 Ten thousand yuan.
In July 2009, the “New Energy Vehicle Manufacturing Enterprise and Product Access Management Rules” was formally implemented.
In March 2010, at the 2010 China Automotive T10 Summit led by the China Association of Automobile Manufacturers, officials from the Ministry of Industry and Information Technology and the Ministry of Science and Technology who once had differences on the path of new energy vehicles finally reached a consensus with China’s six major automobile groups. Regardless of whether electric vehicles, hybrid vehicles or alternative fuel vehicles such as methanol, ethanol, natural gas, etc., as long as they can achieve the goal of energy saving, the state will provide policy support. Four standards related to new energy technologies-“Electric Vehicle Conductive Charging Interface”, “General Requirements for Electric Vehicle Charging Stations”, “Communication Protocol between Electric Vehicle Battery Management System and Off-board Chargers” and “Light Hybrid Electric Vehicles” The “Test Methods for Energy Consumption” has been reviewed by the Ministry of Industry and Information Technology and other relevant departments, and these standards will be issued one after another.
On May 26, 2010, the Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology jointly issued the “Energy-saving Products Benefiting People Project” Energy-saving Vehicles (16L and below Passenger Vehicles) Promotion and Implementation Rules. Gasoline and diesel passenger vehicles (including hybrid and dual-fuel vehicles) that have an engine displacement of 1.L or less and whose comprehensive operating conditions are about 20% lower than the current standard will receive a one-off fixed subsidy based on the standard of 3,000 yuan per vehicle. It is paid directly to consumers by the manufacturer at the time of sale.
On May 31, 2010, the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, and the National Development and Reform Commission jointly issued the “Notice on Carrying out the Pilot Subsidy for Private Purchase of New Energy Vehicles”, which was determined to be in Shanghai, Changchun, Shenzhen, Hangzhou, and Hefei. Wait for 5 cities to start the pilot work of subsidies for private purchase of new energy vehicles. New energy vehicles mainly refer to plug-in hybrid passenger vehicles and pure electric passenger vehicles. For new energy vehicles that meet the support conditions, a subsidy of 3,000 yuan/kWh will be given. The maximum subsidy for plug-in hybrid passenger cars is 50,000 yuan per vehicle; the maximum subsidy for pure electric passenger vehicles is 60,000 yuan per vehicle. The financial subsidy adopts a retreat mechanism. During the pilot period (2010-2012), after each company sells 50,000 plug-in hybrid and pure electric passenger vehicles, the central government will appropriately lower the subsidy standard.
In June 2010, the National Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Finance announced the “Energy-saving Products Benefiting the People Project” Energy-saving Vehicles (1.6L and below Passenger Vehicles) Promotion Catalog.”
In August 2010, the Central Enterprise Electric Vehicle Industry Alliance was established. The alliance is led by the State-owned Assets Supervision and Administration Commission of the State Council and initiated by 16 large central enterprises including FAW Dongfeng, Ordnance Group, Guodian, Nandian, PetroChina, and Sinopec.
In 2011, in the “Twelfth Five-Year Plan” of China’s auto industry, new energy vehicles were listed as the top priority for the development of China’s auto industry in the next five years. Target.
