How to ensure the safety of new energy vehicles from various perspectives PK

Domestic new energy vehicles have also experienced burning events. Hangzhou is a pilot city for new energy vehicles. On the afternoon of April 11, 2011, an electric rental car burns down the street on Wulin Road. In 8 minutes, the car burns only one. Empty shell. The Zhejiang Provincial Institute of Quality Technology and Testing determined that the leakage of the battery electrolyte is the main cause of fire. In this regard, Wu Jianzhong, chairman of the accident automobile production party Zhongtai Automobile, also stated that the safety issue is also their most concern.

Wu Jianzhong: New energy vehicles are still a new thing. There is still much room for improvement in electric technology, business models, and infrastructure. At the same time, during the demonstration operation, safety issues are a top priority. I believe that with new energy vehicles, With the gradual deepening of the marketization process, new energy vehicle standards and safety mechanisms will also be more complete.

According to Yang Yusheng, an academician of the Chinese Academy of Engineering and a researcher at the Institute of Chemical Protection of the General Armament Department, it is a misunderstanding to pay attention to research and development of vehicles and not pay attention to battery R&D.

Yang Yusheng: The battery is the first factor that determines the performance of an electric vehicle. The battery or vehicle input position is reversed, the battery input is small, and the investment in the vehicle is high, which is a point of departure that is eager for quick success.

The United States introduced its own safety standards for electric vehicles, while the electric vehicle has caused a spontaneous combustion accident. For China, the relevant technical standard system from the vehicle to the core key components is still in the limelight. The industry is puzzled by this.

Commentator Jing Yiming also believes that the use of new energy vehicles, especially pure electric vehicles, is still controversial on a global scale.

Jing Yiming: The overall global new energy vehicle is not particularly clear about the direction it is currently looking at globally. The question of whether or not pure electric vehicles are environmentally friendly is also discussed at a relatively enthusiastic level. The vast majority of electricity supply is accomplished by thermal power transmission. Its loss during the process is still relatively large. Reusing it on electric vehicles, including the cost of its batteries, and the cost of disposing and disassembling them after use, is not environmentally friendly enough.

For Chinese companies interested in producing new energy vehicles, the biggest confusion is that the "Energy-saving and New Energy Vehicle Industry Planning (2011-2020)" has not been introduced, there is no direction, there is no standard, companies can only wait, Hefei Guoxuan Hi-Tech Power Co., Ltd. General Manager Fang Jianhua.

Fang Jianhua: If in 2009 or 2010, a new energy car or a pure electric car might be just a concept car, then this year's Frankfurt Auto Show, the Tokyo Motor Show, and all the mainstream electric cars All the depots were introduced. Why? Because they have long coveted China as a huge market.

However, the wait is also culminating. It is reported that after the new energy automobile industry plan was further revised and improved, it was submitted to the State Council executive meeting for review before the “two sessions,” and this was the first data conference of the China Association of Automobile Manufacturers this year. Dong Yang, Secretary-General of China Automobile Association, also stated that this industrial planning is not far behind.

Dong Yang: As far as I understand, energy-saving new energy vehicles are becoming more complete and written, and they will be introduced soon. I feel that it is normal for such a large policy to use months of research and review.
