    The pressure to grow without the pressure of policy subsidies New energy vehicles have a relatively free period of competition Newspaper news (reporter Wang Yali) new energy car does not have policy subsidy, can still live well? Recently, at the new energy vehicle development forum held in Jimo, Li Wei, vice president of Changan automobile, put forward a speech on the new energy market, suggesting that the new energy vehicle market will enter a relatively free competition in the future, causing great repercussions. At present, China's new energy market is obviously driven by policy, and its sales are mainly concentrated in limited purchase cities. After 2020, the market will enter the state of relative free competition. The form of products, especially the pure electric vehicles, will also change from the traditional vehicle based on the traditional platform to the new energy exclusive product developed on the platform of pure electric special platform.

    In general, the lithium ion battery in the battery life made the moment has been decided, the battery life is decided by the specific characteristics of the materials and structures, only according to the material and structure to calculate the battery life is called the theory of life, but in the work of lithium batteries is often expressed as the actual life. The general theory of life will be less than. In general, the lithium ion battery in the battery life made the moment has been decided, the battery life is decided by the specific characteristics of the materials and structures, only according to the material and structure to calculate the battery life is called the theory of life, but in the work of lithium batteries is often expressed as the actual life. The general theory of life will be less than. The extent to which the actual life span does not reach the theoretical life is caused by the non working loss of the capacity.

    Recently, the China Automotive Engineering Society and China Fire Protection Association jointly held a seminar on fire safety of electric vehicles in Beijing. They launched the strategic cooperation research in the field of automotive fire safety, and put the research on fire safety into the working schedule. Fire safety of electric vehicles is particularly important The output of automobiles in China has increased rapidly. In 2002, the annual output of cars in China was only 300. But by 2012, the annual output of cars has exceeded 19 million, which is nearly 6 times higher than that of ten years ago. At the same time, the quality of the car has been exposed. According to the data, from 2008 to 2012, there are more than 10 thousand car fire accidents in China. In 2012, it has reached 14091 cases, with a daily average of 39. This is a new high this year. This shows that the situation of automobile fire is very serious in China. In response, Wu Zhixin, deputy director of China Automotive Technology Research Center, expressed his high approval: "electric vehicle as a new industry, it is more important to ensure its fire safety."
