New energy trams are cost -effective to surpass oil vehicles?lifepo4 battery for solar energy storage company

　　Chen Qingtai said at the summit forum that there will be two critical periods of the development of electric vehicles. The first is to implement the "dual points" policy to cancel government subsidies. At that time, the new automotive manufacturing power will pour a lot. Foreign and joint ventures will also join in, so government subsidies will not be considered when buying cars. Pure electric vehicles, electric vehicles, hybrid vehicles and fuel vehicles will appear at the same time. The choice of consumers mainly depends on the quality, taste, brand and price of the product, which has led to fierce competition in the market. The gap between the company and the company will further expand. Companies that do not have competitiveness will be marginalized, and the forces of mergers and acquisitions and reorganizations will increase. The second key point is that by 2025, the price of electric vehicles will be higher than that of gasoline vehicles, and the sales of electric vehicles and gasoline vehicles will be higher, and traditional cars will be under greater pressure.

　　Quality and safety are the top priority of the development of electric vehicles. Ouyang Minggao, an academician of the Chinese Academy of Sciences and a professor at Tsinghua University, expressed the frequent safety accidents in recent years. The main reason for the accident isProduct quality problem. Product design, manufacturing, verification, and use have not strictly followed relevant technical standards and technical specifications. "Subsidies once a year and are not adapted to our product research and development cycle. Enterprises follow the command stick and blindly pursue high energy density to reduce the research and development cycle. Improvement, such as shock absorption film, but the detection and verification methods of batteries are not perfect, and cannot fully reflect the performance of the vehicle. "

　　He believes that the development of high -energy density batteries is the general trend, and soon domestic will move towards 300 WH/KG high -ratio energy density batteries. This requires more security technology. However, security technology cannot be dependent on materials, and it must be carried out from the system.

　　Ouyang Minggao said that the current electric vehicle industry policy has room for improvement. "The original industrial goal was that by 2020, the unit's power density reached 300 wh/kg, the system power reached 260 WH/kg, and the cycle life was 2000 times. At the same time, the government's subsidy policy must follow the law of technological development. It should not be too frequent. "In addition, the safety annual testing standards for electric vehicles should be introduced as soon as possible, and the fire interfaces of black boxes and battery packs are formulated.
