“The 100-person electric car in China will pay attention to the safety of electric vehicles. It is to prevent problems before they happen.†The head of the China Electric Vehicle 100-member Secretariat at the Summer Forum of the 100-person Summer Forum (2016) and electric vehicle safety on August 12, 2016 The report media exchange said. This media exchange meeting is also a large-scale warm-up meeting of the Summer Forum of the 100-members. Tire Patch is used for nail hole repairs of tires and tubes.

The person in charge believes that the fundamental way to actively solve the safety problem of electric vehicles is innovation. The core driving force for the development of the electric vehicle industry is technological innovation and technological breakthroughs, which provide better safety and convenience for electric vehicles. He also pointed out that security needs to rely on a sound industry management system, and China also needs to establish a management system that is suitable for the development stage of the industry and can ensure the sound development of the industry.
What are the safety problems of electric vehicles? How to solve them? How to achieve active safety? How to adjust the policies of the post-subsidy era in the electric vehicle industry? In the China Electric Vehicles 100-member Summer Forum (2016), we will conduct in-depth discussions on these hot issues. communicate with.
According to the person in charge, the electric vehicle safety report will be released at the Summer Forum of the 100-members (2016). The report will start with four major aspects: vehicle collision safety, high-voltage power safety, waterproof and dustproof safety, and charging facility safety. It will solve the breakdown of battery technology, vehicle structure and policy standards. Drawing on global experience, it puts forward suggestions on technological innovation and policy standards, and comprehensively sorts out the safety of electric vehicles in China.
Ouyang Minggao, executive vice president of the China Electric Vehicle 100-member Association and professor of Tsinghua University, introduced the main contents of the upcoming electric vehicle safety report and conducted in-depth exchanges.
Ouyang Minggao first introduced the safety of electric vehicles from the perspective of battery safety. He pointed out that battery thermal runaway is a major cause of battery safety, which can easily lead to burning accidents in electric vehicles. However, battery thermal runaway can prevent heat transfer between battery systems through strict thermal management, ensuring the safety of drivers and electric vehicles by isolating thermal energy or extending the propagation time of thermal energy. It is understood that the technical team of Tsinghua University, led by Ouyang Minggao, is currently conducting a series of tests and expansion experiments on thermal runaway, and plans to propose relevant standards for heat propagation.
According to Ouyang Minggao, the poor quality of the charging infrastructure is also one of the reasons for the safety accidents of electric vehicles. However, the development of charging infrastructure is more mature than the battery from a technical point of view, so the safety of the charging infrastructure is not difficult to solve. As long as the high quality of the product is guaranteed, the charging of the electric vehicle can be ensured. At present, China has issued corresponding policy standards for the quality and compatibility of charging infrastructure. However, due to the current transition period between new and old standards, there will be a delay period for the implementation and implementation of standards.
In addition, most of the high-voltage systems for electric vehicles are not standardized. In this regard, Ouyang Minggao pointed out that the quality of Chinese cars is good, and a series of policies and regulations are basically the same as those of foreign countries. Therefore, the gap between product quality and foreign products is small. However, due to the excessive number of enterprises and models in China's bus industry, the development cycle of the vehicle is too short, and it is not in place in the high-voltage system of the whole vehicle. Therefore, the bus is one of the key monitoring vehicles of the government.
The head of the 100-member secretariat said that the summer forum (2016) chose the theme of electric vehicle safety as the theme. Electric vehicles are emerging industries, and they are facing a period of transformation and development, and there are many places for improvement. As a new type of industry, it needs innovation and social tolerance. It cannot be suppressed by one or two safety accidents. However, in order to prevent problems before they occur and prevent security accidents from hindering the development of the electric vehicle industry, the Summer Forum (2016) of the Hundred People's Association will focus on safety as a theme, hoping to cause the society to pay more attention to the safety of electric vehicles and find solutions to safety problems. The safety of hundreds of thousands of electric vehicles and the healthy development of the industry are particularly important.
