With the development of science and technology, the development of new energy is imminent. China's new energy vehicles are supported by the national government. However, in today's new energy vehicles, charging piles and battery safety are still the main problems, and this problem is not solved. The development of new energy is bound to be hindered.
Being in the reshaping of the global automotive industry, new energy vehicles are considered to be an important opportunity for China's auto industry to achieve industrial upgrading. When electric vehicles and intelligent networked vehicles become the country's established development goals, the industry's upstream and downstream began to turn their attention to the core issues of cost and efficiency.
Recently released the "White Paper on the Development of New Energy Vehicle Industry in 2017" (hereinafter referred to as "White Paper"), since 2014, the production and sales volume of new energy vehicles in China has experienced a leap-forward growth, with production and sales volume from 79,000 and 7.5 respectively. Ten thousand vehicles have grown to 517,000 vehicles and 507,000 vehicles in 2016. At present, China has become the world's largest new energy vehicle production and sales market, of which sales account for about 45% of the global new energy vehicle market.
In April 2015, the Ministry of Finance issued the Notice on the Financial Support Policy for the Promotion and Application of New Energy Vehicles in 2016-2020, including the Notice on Printing and Developing the Infrastructure for Electric Vehicle Charging Infrastructure (2015-2020) and New A series of new energy vehicle related policies, such as the Energy Vehicle Carbon Quota Management Measures (Draft for Comment) and the Notice on Adjusting the Financial Subsidy Policy for the Promotion and Application of New Energy Vehicles, have been introduced. In March of this year, the Ministry of Industry and Information Technology, the Ministry of Development and Reform, the Ministry of Science and Technology, and the Ministry of Finance jointly issued the Action Plan for Promoting the Development of Automotive Power Battery Industry, aiming to accelerate the development of China's automotive power battery industry and promote new energy vehicles. The industry is healthy and sustainable.
The white paper analysis pointed out that the trend of China's new energy vehicle national policy orientation is mainly reflected in strengthening the standardized management of the new energy automobile industry, highlighting the safety management of new energy vehicle products and strengthening the standardization of new energy vehicles.
The technology-oriented trend covers three dimensions of power battery, fuel cell and charging facility.
Among them, the state requires to enhance the international competitiveness of the power battery industry chain, promote the use of power battery ladders, establish a power battery recycling system linked by upstream and downstream enterprises; at the same time increase the research and development of power battery technology, strive to break through high security and long in the field of power battery Technical bottlenecks such as longevity and high energy density lithium-ion batteries break through high-capacity positive and negative materials, high-safety separators and functional electrolyte technologies in key materials.
Promote the development of fuel cell vehicles, improve the overall engineering level of fuel cell vehicles from fuel cell stacks, key components of systems, and related materials; promote the development of hydrogenation and hydrogen storage technologies, promote the construction of hydrogen refueling stations, and make up for the fuel cell industry. Chain related weaknesses.
The performance of charging facilities is to increase the R&D of science and technology and encourage the innovation of business models to promote the industry forward. In research and development, we will accelerate the development of new power-on-replacement technologies and equipment such as high power density, high conversion efficiency, high applicability, wireless charging, and mobile charging.
The main problems of China's new energy vehicles are concentrated on the safety hazards of new energy auto parts, the slow layout of charging infrastructure and the professional qualifications of new energy auto practitioners.
In response to the safety hazards of new energy auto parts, the white paper lists many items of mandatory safety standards for new energy vehicles, including energy storage devices, operational safety and fault protection, personnel electric shock protection, collision safety, EMC (electromagnetic compatibility), and Low speed sounds, etc.
The main high-voltage system components inside the new energy vehicle include inverters with drive motors, on-board chargers, DC/DC and AC/DC converters, electric heaters and high-voltage battery packs. EMC testing of the above components is combined with high voltage. The wire environment, the high-voltage wiring harness inside the car and the related tests of the battery will provide a guarantee for eliminating the safety hazards of new energy auto parts.
As for the professional qualifications of new energy vehicles, there are no corresponding standards and requirements in China. In April 2012, Germany established the qualification standard for new energy vehicle technology practitioners - BGI/GUV - I8686E. According to the scope of work and risk level of the practitioners, the training is divided into non-high voltage electric working and high voltage without electric environment. The system works, the high-voltage system of the charged environment works three levels, or it will be of reference.
