Power battery opportunities and challenges coexist, cost and core technology are the key

　　Ye Shengji, deputy secretary-general of the China Association of Automobile Manufacturers, believes that at present, my country’s automobile industry is not strong. Although the annual production and sales of new energy vehicles have reached the goal of over 700,000 vehicles, they still need to work hard on product upgrades and core technology upgrades. .

　　On April 21, the "2018 China New Energy Power Battery and Energy Storage Industry Conference" was held in Taizhou, Jiangsu. In the sub-forum with the theme of "Opportunities·Innovation·Breakthrough", many power battery experts, scholars and representatives of power battery companies talked freely about the opportunities and challenges currently faced by the power battery industry.

　　Ye Shengji, deputy secretary-general of the China Association of Automobile Manufacturers, believes that at present, my country’s automobile industry is not strong. Although the annual production and sales of new energy vehicles have reached the goal of over 700,000 vehicles, they still need to work hard on product upgrades and core technology upgrades. . Ye Shengji said that my country's new energy automobile industry is not yet mature, and there is still a lot of room for development of key core technologies, and there is still a long way to go for infrastructure and environmental construction.

　　Wang Fang, chief expert of China Automotive Technology Research Center, introduced her research and views on power battery standards and test evaluation to the guests. Statistics show that the energy density and group efficiency of power batteries have been greatly improved. In terms of packaging structure, the group efficiency of soft pack batteries is higher than other packaging structures. In terms of the full life cycle performance of the power battery, she divided the test evaluation into three aspects: usable, controllable and disaster hazard evaluation, in order to better evaluate the power battery.

　　Liu Yanlong, secretary general of China Chemical and Physical Power Supply Industry Association, introduced some of the development of the power battery industry to the guests. In 2017, the domestic lithium battery market reached about 113 billion yuan, of which the power lithium battery scale was about 60 billion yuan, and the assembly volume reached about 10.5 billion watt-hours. He said that since 2015, first-line companies in the power battery industry have expanded their market share through technological advantages, and some companies with no advantages are facing the danger of being eliminated. The power battery industry has entered a period of rapid reshuffle, and this trend will be further accelerated in the future. Companies must not only have strong technical and financial support, but also continue to invest in rational market positioning and rapid market response capabilities in order to win market.

　　Li Xiaoping, chief scientist of Nandu Power Lithium Battery, also explained the relationship between the new energy industry and power batteries from the perspective of systems engineering. He pointed out that every part of the system is excellent, but the entire system is not necessarily optimal. On the contrary, if the system is to be optimized, some sacrifices must be made locally.

　　Zhang Chunyu, Director of the Second Division of BYD Battery Business Group, introduced BYD's development route in power batteries. She said that due to the increase in the price of raw materials, it can affect the choice of end consumers for electric vehicles. In order to reduce such impact, BYD will continue to develop lithium iron phosphate batteries.

　　Qiu Zeyou, chairman of Miaosheng Power Technology Co., Ltd., introduced Miaosheng Power’s experience in subcontracting power replacement; Li Bingjiang, director of the R&D Center of Jiangsu Zhihang New Energy Co., Ltd., introduced the development of Zhihang New Energy in power battery products. ; Wu Hui, Research Director of Ivey Economic Research Institute, shared his mid-to-long-term outlook for China's automotive power battery industry.

　　In the high-end dialogue session, industry representatives from the fields of power battery upstream materials, battery manufacturing, manufacturing equipment, industrial investment and energy storage shared their expectations for the future development of the power battery industry.
